609慣例是關于為冷卷鋼鐵面板的塗料,光澤面,反塗層,及相關塗層產品測試.D

膠紙測試5.儀器與材料5.1切割模具-----鋒利的剃刀刃,解剖刀,水果刀或其它的切割器具.且刀刃是否鋒利尤其重要.5.2切割指導-----用尺于鋼鐵與硬金屬上畫直線以確保垂直切割.5.3膠紙------供應商與用戶需要而達成協議的帶有強粘性的一英寸(25-mm)寬的半透明膠紙.因為這種強粘著力卷與卷不同時間段也有差異.當在不同的實驗室里進行測試時,用于批量的膠紙要相同,這點非常重要.如果此測試方法權用于少放一系列的測試烤漆層,那么是不可能的. 5.4橡皮擦位于鉛筆的末端.5.5照明度-----足夠的光源有助于判斷划割是否已深入底層.6.測試樣本6.1當用至此測試方法時,樣本須是可估計附著力的已噴漆結構或部件.6.2.為試驗之用,把這種期望得到表面條件和各成分的附著力的面板用于測試當中.注意3----在慣例D609與慣例D1730與D2092里有所給出的可應用的測試面板規格與表面預備方法.注意4----塗層的應用應符合慣例D823,或根據買賣雙方達成的協議來決定.注意5----若有要求或有規定,在執行膠紙測試之前,已塗裝的測試面板也應進行例如:沉浸入水,鹽霧噴濺,或高溫度放置等一系初步的處理,進行初步處理的時間和各種條件應根據最終使用者或根據買賣雙方的協議進行調整.7.步驟7.1選取一塊沒有瑕疵的部位來測試它的不完整性.要求所測試部位干淨且干燥.特別是溫度或相關濕度可能會影響膠紙的附著力或烤漆層.7.2在膜層上划兩個大約1.5英寸(40mm)長且在30到45º之間的小角交叉的划割線.切割時,用尺畫直線且切除烤漆層,在一穩定動作情況下露出底層.7.3利用自金屬底層的光的反射現象來檢查切口,如果沒有透過底層,那么在另外一個不同的位置再划一個切口.不要加深以前的切口,這樣可能影響切口的附著力.7.4 把強粘著力膠紙兩頭重疊的部分找到并把多余的一小部分丟掉,均勻用力(不是猛拉)把另外長端拉出且切出約3in/75mm的一片.7.5把膠紙的中端位置在切口交叉處并在最小(較小)的角度以相同的方向(把膠紙壓平)用手指把切口位置的膠紙壓平,然后用橡皮擦壓牢,當貼粘很好時,從透明膠紙下的顏色則可以看得出來.7.6在應用的90±30s時間里,抓住膠紙未粘住的末端來移除膠紙,并以一個接近180°角來快速拉起(不要猛拉).7.7檢查X切割區域塗裝脫落狀況,根據以下等級來判定塗裝測試的附著力:5A 表面塗裝無脫落.4A 切口或交叉處有少量脫落3A 切口任一邊有達1.6mm參差不齊之脫落2A 切口任一邊有達超過3.2mm參差不齊之脫落1A 膠紙下面可見X大部分區域有塗裝脫落0A 塗裝脫落現象超過了X區域之外7.8在每個測試面板上另外選取兩個不同的位置重復測試.大結構的部件也要測試以確保附著力評估對整個表面具有代表性.7.9做几次測試后應檢查刀具的刃口,如有必要,在再次使用之前把刀具在砂紙上輕輕地打磨,丟掉那些刃口被磨掉的刀具或會給被覆造成額外損傷的有其它缺陷的刀具.8.匯報8.1匯報應寫明測試的次數,及每次的具體現象及描述,若是多層塗裝還應寫明脫落(或未通過測試)的發生時機,是在第一層烤漆與底層之間,還是在第一層或第二層塗層之間,等.8.2匯報測試時的結構或測試部件,位置與環境狀況.8.3為測試面板匯報測試時所測試底層,烤漆類型,凝固方法,及環境狀況.8.4如果所測定的膠紙附著力強度符合測試方法D 1000或D3330,那么匯報附著力比率結果.如果沒有測定膠紙的粘性強度,那么匯報使用的具體膠紙與它的制造商.9.精確度與偏差9.1用三個面板上三種不同的膜層在一個interlaboratory里用此測試方法,在六個實驗室里的操作員在三個面板上三種不同的膜層塗上大範圍的粘膠然后做一附著力測量,在實驗室內的標准偏差為0.33,而在實驗室之間的標准偏差為0.44.基于這些偏差,以下標准使用于以一個95%可信度水平來判斷結果的可接受性:9.1.1重復性-----在大面積的表面附著力應一致,在兩次測量時通過相同的操作員來獲得的結果不同,且超過1個比率單位的話,那么就值得懷疑.9.1.2再生性-----兩種測試結果,每種結果都有三次相同的測試,如果它來自于不同的操作者,所造成的偏差超過1.5個單位的話,那么我們就可以認為這兩種測試結果也是不可信的.方法B------十字切割膠紙測試10.儀器與材料10.1切割工具-----剃刀,手術刀(解剖刀),小刀或其它在15°--30°之間有一切割邊角度且能立即切割一個切口或多個切口的切割器具,特別重要的是必須有好的刃口(刃角).10. 2 划割指導----手工切割鋼鐵或直線切割其它硬金屬或某金屬都要確保直線切割.10.3慣例----調整鋼尺刻度在0.5mm用于測量單個的切口.10.4膠紙,見5.3中描述.10.5橡皮擦位于鉛筆末端.10.6照明度,見5.5中描述.10.7放大鏡-----放大鏡可用于當切單個的切口和檢查測試區域時.11.測試樣本11.1測試樣本應如Section 6中所述,然而還須注意,百格刀的使用效果雖好,但僅用在測試十分平整的區域上,且這樣區域的平整性應使百格刀的所有刃口在划割底層時能保持相同的划割程度,檢查平面直角刃口諸如10.3所述用鋼尺(調節的).12.步驟12.1在進行膠紙測試之前,何地要求或何時同意樣本屬于一個預補測試(見注釋3).除非同意要求D3924標准中所述溫度,在干燥或檢查塗層后,應在如D3924所述(定義的)室溫中執行膠紙測試.CLASSIFICATION

Results12.2選擇一個無臟污,理想的主要表面作為測試面,放置于一穩定底座上,在放大鏡下,按以下描述的方法划割平行的切口.12.2.1除非另行規定,那么對于膜層的厚度達到2.0mils且包括2.0mils(50μm)的應划割11條,且每條相隔距離為1mm.12.2.2對于已干燥的塗裝膜厚在50—125μm,划割6條且每條相隔距離2mm,對于大于5mils 的膜厚測試用方法A.12.2.3所有划割條應約長3/4in(20mm),划割時用力適度,手法穩定并使切口深及底層,當你在使用直尺或其它輔助工具划單個一條方格時,應把直尺或其它輔助工具放在沒有划割的地方.12.3划完方格后應用柔軟的刷子或棉紙輕輕刷掉方格表面的雜質.12.4檢查刀具的刃口,如有必要,對刀口已卷或已平的地方在好的砂紙上輕輕打磨.以90°角在原切口的中心切割額外的切口.12.5刷所划割區域之前應首先利用自底層的光的反射作用來檢查切口,如果切口未深及鐵底,那么就選擇在另外一不同的地方重新再划百格.12.6剪一段長3in(75mm)的膠紙(與所划百格處大小相仿),并移除/丟棄兩端多余的部份.12.7放這段膠紙于中間位置貼緊百格并用手把它壓平,為確保膠紙與百格接角緊密還須用橡皮來回磨擦表面壓牢,如果膠紙粘貼很好時,膠紙下的顏色則可以判斷出來.12.8約過90±30s的時間,然后抓起膠紙未粘住的一端,盡量保持180°夾角迅速拉起(不可猛拉).12.9用放大鏡來檢查百格區域是否掉漆脫落,根據下面圖示1描述來判斷附著力的等級.5B:切口完全平滑,百格無任何脫落現象.4B:切口交叉處塗裝(層)有少許脫落,少許5%區域受到影響.3B:切口邊緣和交叉處塗裝(層)有少許脫落,5%--15%之間的百格區域受到影響.2B:百格的部分和切口邊緣塗層有薄片剝落,15%--35%的百格區域受到影響.1B:切口處邊緣有帶狀塗層剝落,且有整個柵格脫落現象,35%—60%的百格區域受到影響.0B:脫落現象比Grade1更差.13匯報13.1匯報應含有測試的次數,它們的意思和範圍,對于多層塗裝,還應匯報是在哪一層塗層發生了脫落,是第一層塗層與底層之間,還是第一層塗層與第二層塗層之間.13.2匯報應用的底層,塗裝類型及加工處理的方法.13.3若膠紙粘著力已根據D1000或D3330中所規定的使用,就可直接匯報附著力等級結果.若使用膠紙的粘著力沒有決定,還應匯報它的規格及生產廠商.14.精確性和偏差性8操作員在其中的六個實驗室里對塗有三層塗層的三個面板所進行的附著力的測試,與其它操作員在六個實驗室里的對塗有四種不同的兩個面板所進行的附著力的測試的基礎上,它們所共有的標准偏差在實驗室之內是0.37、之間是0.7.基于這些標准偏差,以下標准可使用為以95%的可信度水平來判斷結果的可接受性.14.1.1重復性-----如果整個大的表面附著力是統一的,同一個操作者在兩次測試中之間的偏差超過了1個等級,那么這個測試結果就是不可信的.14.1.2再生性-----兩個測試結果,每一種測試結果都有兩個或三個同樣的測試數據,如果它來自于不同的操作者所造成的偏差大于兩個等級的話,那么這兩種結果都是不可信的.14.2這些測試方法不能有偏差.15.關鍵字15.1附著力,膠紙,橫切附著力,測試方法,膠紙附著力測試方法,X形切口附著力測試方法.附錄(參考信息)X1 注釋X1.1緒論X1.1.1附著力測試步驟的已有的復雜性,附著力能測試出來嗎?附件參考Mittal(1)12已有指出來,答案是和否并存.合理的講,目前還沒有任何現存的測試能精確地鑒定一種粘著結合物的實際物理粘著力,但是我們卻可以說我們能夠獲得粘著性能的一種相關跡象去詮釋它.X1.1.2實際的附著力測試方法,一般有兩種類型:暗指的和直接的.”暗指的”測試包括鑒別或描述技術,磨擦測試,磨損測試.當把他們用于量化粘著結合物的附著力的時候,就出現了對這些測試方法的批判.但是實際上這不是他們的目的.在實際工作環境下,一種”暗指的”測試方法用于鑒定塗裝性能.這種類型富有意義的測試有很高的探索價值.首先,因為這種測試結果是用一個單個的不連續量來表示,其次割裂塗層/底層的力度是在規定的條件下.直接測試包括Hesiometer與塗粘計(2).一般直接測試方法是剝落,lapshear(重剪切),與拉力測試.X1.2測試方法X1.2.1在實踐中,測試的數據類型已用于試圖評估通過不同模型來減少結合物的破裂.為一測試認為標准的重要性是保証大規模的可接受性是:用易懂的,明確的步驟:適當預期的應用,重復性和再生性,和可量化,包括鑒定性能有意義的等級範圍.X1.2.2用于金屬塗裝的測試方法有:剝落附著力或膠紙測試;加德納衝擊彈性測試;與包括剪切的附著力混合測試和直接抗拉力測試.雖然這些測試不能確實地滿足所列出的標准,但他們吸引人的地方是在使用設置/儀器方面很容易被接受,并(或)能夠獲得在合理的成本上.X1.2.3在附著力測試方面,隨著時間的推移,這些測試方法的廣泛差異性及多樣性已得到發展(1-5),然而,普遍的問題和困難是相關這些測試以粘著現象為判定基礎.(一般來說,在相關這些測試的基礎的粘著現象方面存在困難).X1.3膠紙測試X1.3.1到目前為止鑒定塗裝附著力最普遍的方法是膠紙和脫落測試,其從20世紀30年代開始就已經使用.在它最簡單的版本中,用一片粘著膠紙貼緊塗層觀察膠紙何時脫落以判定它的粘著力和粘著程度.直到可評估附著力的完整塗層不再頻繁脫落,在使用和移走膠紙之前,這種測試的嚴格性通常被划割塗層的x形切口或交叉切口模式所加強.然后,附著力就是脫落的皮膜與已規定的等級範圍做比較而被評估出來的.若一個完整的塗層被膠紙粘著脫得很干淨,或者如果是無使用膠紙僅僅是划破塗層的情況下就脫落.我們就可以很單純地判斷這種附著很糟糕或非常糟糕,如此塗層更精確的評估不在這種測試的能力之內.X1.3.2目前普遍使用的版本第一次出版是1974年,在這個標准中涵蓋了兩種測試方法,這兩測試方法過去都用于確定一種底材塗層的附著力是否在一個足夠的級別上;然而,他們不去辨別對于被要求更加精密的測試方法的附著力的較高等級.膠紙測試的主要局限性是它的低敏感性,僅適用于低粘著力的相關塗裝,以及當我們單獨地測試原始塗裝時或在多層塗裝中各塗層之間或塗法之內,這種底材的塗裝附著力是不能確定的.X1.3.3這兩種方法的鐵材塗裝的再現性(重復性)通過觀察,一般結果是在1個等級單位以內,再生性一般在1-2個等級之間.膠紙測試廣泛普及且觀察簡單成本低廉!通過數十年的運用之后,人們感覺很舒適,把此種方法應用于鐵,很經濟的完成了它在的工作場所的應用且最具重要性.X1.3.4當把一種彈性附著力膠紙應用于一種鋼性底材表面的塗裝時,爾后移除,這個移除的步驟已經被描述在”脫落現象”術語中,見圖x1-1.X1.3.5以鋸齒狀的主要邊開始脫落,沿著塗層粘性/分界面或塗層/襯底分界面繼續脫落,且取決于相關結合力度.假設當拉力沿著后分界面產生的時候,出現塗層移除,此后分界面是襯背的流變學特性的一種功能與粘性塗層物料,是比塗層襯底分界面(或塗層的粘著強度)上結合強度還要大.實際上此拉力應用于連續距離(O-A)見Fig.X1.1,直接相關于所述的特性,而不是根據在理論案例里,在Fig.X1.1里以一點(O)來集中--------盡管原來的兩者的拉力最大.一重要壓縮力出現是從膠紙襯背物料的回應到伸展,因此,拉力與壓縮力都包括附著力測試.X1.3.6關于所使用的膠紙的自然性與程序本身的一定的方面所顯露出來的因素,停止膠紙測試的詳細審查,每個或任何結合體都會據(6)里所述戲劇性地影響測試結果(6).X1.4在塑膠底材上做附著力測試(粘著脫落測試)X1.4.1膠紙測試除了用于金屬底材以外,就不適用于其它的襯底,如塑膠襯底就不行.這個中心問題是塑膠底材測試缺乏再生性并且沒有聯系到應有的應用.兩者的關系有以下發現:糟糕的精確性是這種應用材料的几個內在的特征的一個直接結果和它本身的步驟.較重要的是在這些情況下,這種測試超過了他的應用範圍,這些測試方法是為了應用于鐵底材相關柔軟的塗裝而設計的.不是為應用于塑膠件的塗裝(通常較脆)(7).在實踐中,塑膠底材塗裝的獨特功能要求導致在做附著力測試中,一般/通常的膠紙測試不能達到滿意的效果.X1.5膠紙的選用FIG.X1.1

method to lower levels of adhesion (see 1.3)should be recognized before using it.The intra-and inter-laboratory precision of this test method is similar to other widely-accepted tests for coated substrates (for example,Test Method D 2370and Test Method D 4060),but this is partly the result of it being insensitive to all but large differences in adhesion.The limited scale of 0to 5was selected deliberately to avoid a false impression of being sensitive.TEST METHOD A—X-CUT TAPE TEST5.Apparatus and Materials5.1Cutting Tool —Sharp razor blade,scalpel,knife or other cutting devices.It is of particular importance that the cutting edges be in good condition.5.2Cutting Guide —Steel or other hard metal straightedge to ensure straight cuts.5.3Tape —25-mm (1.0-in.)wide semitransparent pressure-sensitive tape 7with an adhesion strength agreed upon by the supplier and the user is needed.Because of the variability in adhesion strength from batch-to-batch and with time,it is essential that tape from the same batch be used when tests are to be run in different laboratories.If this is not possible the test method should be used only for ranking a series of test coatings.5.4Rubber Eraser ,on the end of a pencil.5.5Illumination —A light source is helpful in determining whether the cuts have been made through the film to the substrate.6.Test Specimens6.1When this test method is used in the field,the specimen is the coated structure or article on which the adhesion is to be evaluated.6.2For laboratory use apply the materials to be tested to panels of the composition and surface conditions on which it is desired to determine the adhesion.N OTE 3—Applicable test panel description and surface preparation methods are given in Practice D 609and Practices D 1730and D 2092.N OTE 4—Coatings should be applied in accordance with Practice D 823,or as agreed upon between the purchaser and the seller.N OTE 5—If desired or specified,the coated test panels may be subjected to a preliminary exposure such as water immersion,salt spray,or high humidity before conducting the tape test.The conditions and time of exposure will be governed by ultimate coating use or shall be agreed upon between the purchaser and seller.7.Procedure7.1Select an area free of blemishes and minor surface imperfections.For tests in the field,ensure that the surface isclean and dry.Extremes in temperature or relative humidity may affect the adhesion of the tape or the coating.7.1.1For specimens which have been immersed:After immersion,clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating.Then dry or prepare the surface,or both,as agreed upon between the purchaser and the seller.7.2Make two cuts in the film each about 40mm (1.5in.)long that intersect near their middle with a smaller angle of between 30and 45°.When making the incisions,use the straightedge and cut through the coating to the substrate in one steady motion.7.3Inspect the incisions for reflection of light from the metal substrate to establish that the coating film has been penetrated.If the substrate has not been reached make another X in a different location.Do not attempt to deepen a previous cut as this may affect adhesion along the incision.7.4Remove two complete laps of the pressure-sensitive tape from the roll and discard.Remove an additional length at a steady (that is,not jerked)rate and cut a piece about 75mm (3in.)long.7.5Place the center of the tape at the intersection of the cuts with the tape running in the same direction as the smaller angles.Smooth the tape into place by finger in the area of the incisions and then rub firmly with the eraser on the end of a pencil.The color under the transparent tape is a useful indication of when good contact has been made.7.6Within 90630s of application,remove the tape by seizing the free end and pulling it off rapidly (not jerked)back upon itself at as close to an angle of 180°as possible.7.7Inspect the X-cut area for removal of coating from the substrate or previous coating and rate the adhesion in accor-dance with the following scale:5A No peeling or removal,4A Trace peeling or removal along incisions or at their intersection,3A Jagged removal along incisions up to 1.6mm (1⁄16in.)on either side,2A Jagged removal along most of incisions up to 3.2mm (1⁄8in.)on either side,1A Removal from most of the area of the X under the tape,and 0ARemoval beyond the area of the X.7.8Repeat the test in two other locations on each test panel.For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface.7.9After making several cuts examine the cutting edge and,if necessary,remove any flat spots or wire-edge by abrading lightly on a fine oil stone before using again.Discard cutting tools that develop nicks or other defects that tear the film.8.Report8.1Report the number of tests,their mean and range,and for coating systems,where the failure occurred that is,between first coat and substrate,between first and second coat,etc.8.2For field tests report the structure or article tested,the location and the environmental conditions at the time of testing.8.3For test panels report the substrate employed,the type of coating,the method of cure,and the environmental conditions at the time of testing.8.4If the adhesion strength of the tape has been determined in accordance with Test Methods D 1000or D 3330,report the7Permacel 99,manufactured by Permacel,New Brunswick,NJ 08903,and available from various

this subcommittee that the properties of these tapes were ers of it should,therefore,check whether current material gives comparable results to previous suppliedmaterial.results with the adhesion rating(s).If the adhesion strength of the tape has not been determined,report the specific tape used and its manufacturer.8.5If the test is performed after immersion,report immer-sion conditions and method of sample preparation.9.Precision and Bias89.1In an interlaboratory study of this test method in which operators in six laboratories made one adhesion measurement on three panels each of three coatings covering a wide range of adhesion,the within-laboratories standard deviation was found to be0.33and the between-laboratories0.44.Based on these standard deviations,the following criteria should be used for judging the acceptability of results at the95%confidence level:9.1.1Repeatability—Provided adhesion is uniform over a large surface,results obtained by the same operator should be considered suspect if they differ by more than1rating unit for two measurements.9.1.2Reproducibility—Two results,each the mean of trip-licates,obtained by different operators should be considered suspect if they differ by more than1.5rating units.9.2Bias cannot be established for these test methods.TEST METHOD B—CROSS-CUT TAPE TEST 10.Apparatus and Materials10.1Cutting Tool9—Sharp razor blade,scalpel,knife or other cutting device having a cutting edge angle between15 and30°that will make either a single cut or several cuts at once.It is of particular importance that the cutting edge or edges be in good condition.10.2Cutting Guide—If cuts are made manually(as opposed to a mechanical apparatus)a steel or other hard metal straight-edge or template to ensure straight cuts.10.3Rule—Tempered steel rule graduated in0.5mm for measuring individual cuts.10.4Tape,as described in5.3.10.5Rubber Eraser,on the end of a pencil.10.6Illumination,as described in5.5.10.7Magnifying Glass—An illuminated magnifier to be used while making individual cuts and examining the test area.11.Test Specimens11.1Test specimens shall be as described in Section6.It should be noted,however,that multitip cutters10provide good results only on test areas sufficiently plane that all cutting edges contact the substrate to the same degree.Check forflatness with a straight edge such as that of the tempered steel rule (10.3).12.Procedure12.1Where required or when agreed upon,subject the specimens to a preliminary test before conducting the tape test (see Note3).After drying or testing the coating,conduct the tape test at room temperature as defined in Specification D3924,unless D3924standard temperature is required or agreed.12.1.1For specimens which have been immersed:After immersion,clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating.Then dry or prepare the surface,or both,as agreed upon between the purchaser and the seller.12.2Select an area free of blemishes and minor surface imperfections,place on afirm base,and under the illuminated magnifier,make parallel cuts as follows:12.2.1For coatings having a dryfilm thickness up to and including2.0mils(50µm)space the cuts1mm apart and make eleven cuts unless otherwise agreed upon.12.2.2For coatings having a dryfilm thickness between2.0 mils(50µm)and5mils(125µm),space the cuts2mm apart and make six cuts.Forfilms thicker than5mils use Test Method A.1112.2.3Make all cuts about20mm(3⁄4in.)long.Cut through thefilm to the substrate in one steady motion using just sufficient pressure on the cutting tool to have the cutting edge reach the substrate.When making successive single cuts with the aid of a guide,place the guide on the uncut area.12.3After making the required cuts brush thefilm lightly with a soft brush or tissue to remove any detachedflakes or ribbons of coatings.12.4Examine the cutting edge and,if necessary,remove anyflat spots or wire-edge by abrading lightly on afine oil stone.Make the additional number of cuts at90°to and centered on the original cuts.12.5Brush the area as before and inspect the incisions for reflection of light from the substrate.If the metal has not been reached make another grid in a different location.12.6Remove two complete laps of tape and discard.Re-move an additional length at a steady(that is,not jerked)rate and cut a piece about75mm(3in.)long.12.7Place the center of the tape over the grid and in the area of the grid smooth into place by afinger.To ensure good contact with thefilm rub the tapefirmly with the eraser on the end of a pencil.The color under the tape is a useful indication of when good contact has been made.12.8Within90630s of application,remove the tape by seizing the free end and rapidly(not jerked)back upon itself at as close to an angle of180°as possible.12.9Inspect the grid area for removal of coating from the substrate or from a previous coating using the illuminated magnifier.Rate the adhesion in accordance with the following scale illustrated in Fig.1:8Supporting data are available from ASTM International Headquarters.Request

three coatings covering a wide range of adhesion and in the other operators in six laboratories made three measurements on two panels each of four different coatings applied over two other coatings,thepooled standard deviations for within-and between-laboratories were found to be0.37and0.7.Based on these standard deviations,the following criteria should be used for judging the acceptability of results at the95%confidence level:14.1.1Repeatability—Provided adhesion is uniform over a large surface,results obtained by the same operator should be considered suspect if they differ by more than one rating unit for two measurements.14.1.2Reproducibility—Two results,each the mean of du-plicates or triplicates,obtained by different operators should be considered suspect if they differ by more than two rating units.14.2Bias cannot be established for these test methods.15.Keywords15.1adhesion;crosscut adhesion test method;tape;tape adhesion test method;X-cut adhesion testmethodFIG.1Classification of Adhesion TestResultsAPPENDIX(Nonmandatory Information)MENTARYX1.1IntroductionX1.1.1Given the complexities of the adhesion process,can adhesion be measured?As Mittal (1)12has pointed out,the answer is both yes and no.It is reasonable to state that at the present time no test exists that can precisely assess the actual physical strength of an adhesive bond.But it can also be said that it is possible to obtain an indication of relative adhesion performance.X1.1.2Practical adhesion test methods are generally of two types:“implied”and “direct.”“Implied”tests include inden-tation or scribe techniques,rub testing,and wear testing.Criticism of these tests arises when they are used to quantify the strength of adhesive bonding.But this,in fact,is not their purpose.An “implied”test should be used to assess coating performance under actual service conditions.“Direct”mea-surements,on the other hand,are intended expressly to measure adhesion.Meaningful tests of this type are highly sought after,primarily because the results are expressed by a single discrete quantity,the force required to rupture the coating/substrate bond under prescribed conditions.Direct tests include the Hesiometer and the Adherometer (2).Com-mon methods which approach the direct tests are peel,lap-shear,and tensile tests.X1.2Test MethodsX1.2.1In practice,numerous types of tests have been used to attempt to evaluate adhesion by inducing bond rupture by different modes.Criteria deemed essential for a test to warrant large-scale acceptance are:use of a straightforward and unam-biguous procedure;relevance to its intended application;re-peatability and reproducibility;and quantifiability,including a meaningful rating scale for assessing performance.X1.2.2Test methods used for coatings on metals are:peel adhesion or “tape testing;”Gardner impact flexibility testing;and adhesive joint testing including shear (lap joint)and direct tensile (butt joint)testing.These tests do not strictly meet all the criteria listed,but an appealing aspect of these tests is that in most cases the equipment/instrumentation is readily avail-able or can be obtained at reasonable cost.X1.2.3A wide diversity of tests methods have been devel-oped over the years that measure aspects of adhesion (1-5).There generally is difficulty,however,in relating these tests to basic adhesion phenomena.X1.3The Tape TestX1.3.1By far the most prevalent test for evaluating coating “adhesion”is the tape-and-peel test,which has been used since the 1930’s.In its simplest version a piece of adhesive tape is pressed against the paint film and the resistance to and degreeof film removal observed when the tape is pulled off.Since an intact film with appreciable adhesion is frequently not removed at all,the severity of the test is usually enhanced by cutting into the film a figure X or a cross hatched pattern,before applying and removing the tape.Adhesion is then rated by comparing film removed against an established rating scale.If an intact film is peeled cleanly by the tape,or if it debonds just by cutting into it without applying tape,then the adhesion is rated simply as poor or very poor,a more precise evaluation of such films not being within the capability of this test.X1.3.2The current widely-used version was first published in 1974;two test methods are covered in this standard.Both test methods are used to establish whether the adhesion of a coating to a substrate is at an adequate level;however they do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.Major limitations of the tape test are its low sensitivity,applicability only to coatings of relatively low bond strengths,and non-determination of adhesion to the substrate where failure occurs within a single coat,as when testing primers alone,or within or between coats in multicoat systems.For multicoat systems where adhesion failure may occur between or within coats,the adhesion of the coating system to the substrate is not determined.X1.3.3Repeatability within one rating unit is generally observed for coatings on metals for both methods,with reproducibility of one to two units.The tape test enjoys widespread popularity and is viewed as “simple”as well as low in cost.Applied to metals,it is economical to perform,lends itself to job site application,and most importantly,after decades of use,people feel comfortable with it.X1.3.4When a flexible adhesive tape is applied to a coated rigid substrate surface and then removed,the removal process has been described in terms of the “peel phenomenon,”as illustrated in Fig.X1.1.X1.3.5Peeling begins at the “toothed”leading edge (at the right)and proceeds along the coating adhesive/interface or the coating/substrate interface,depending on the relative bond strengths.It is assumed that coating removal occurs when the tensile force generated along the latter interface,which is a function of the rheological properties of the backing and adhesive layer materials,is greater than the bond strength at the coating-substrate interface (or cohesive strength of the coat-ing).In actuality,however,this force is distributed over a discrete distance (O-A)in Fig.X1.1,which relates directly to the properties described,not concentrated at a point (O)in Fig.X1.1as in the theoretical case—though the tensile force is greatest at the origin for both.A significant compressive force arises from the response of the tape backing material to being stretched.Thus both tensile and compressive forces are in-volved in adhesion tape testing.X1.3.6Close scrutiny of the tape test with respect to the12The boldface numbers in parentheses refer to the list of references at the end of this testmethod.nature of the tape employed and certain aspects of the procedure itself reveal several factors,each or any combination of which can dramatically affect the results of the test as discussed (6).X1.4Peel Adhesion Testing on Plastic SubstratesX1.4.1Tape tests have been criticized when used for substrates other than metal,such as plastics.The central issues are that the test on plastics lacks reproducibility and does not relate to the intended application.Both concerns are well founded:poor precision is a direct result of several factors intrinsic to the materials employed and the procedure itself.More importantly,in this instance the test is being applied beyond its intended scope.These test methods were designed for relatively ductile coatings applied to metal substrates,not for coatings (often brittle)applied to plastic parts (7).The unique functional requirements of coatings on plastic sub-strates cause the usual tape tests to be unsatisfactory for measuring adhesion performance in practice.X1.5The Tape ControversyX1.5.1With the withdrawal from commerce of the tape specified originally,3M No.710,current test methods no longer identify a specific tape.Differences in tapes used can lead to different results as small changes in backing stiffness and adhesive rheology cause large changes in the tension area.Some commercial tapes are manufactured to meet minimum standards.A given lot may surpass these standards and thus be suitable for general market distribution;however,such a lot may be a source of serious and unexpected error in assessing adhesion.One commercially available tape test kit had in-cluded a tape with adhesion strength variations of up to 50%claimed by the manufacturer.Also,because tapes change on storage,bond strengths of the tape may change over time (7,8).X1.5.2While there are tapes available that appear to deliver consistent performance,a given tape does not adhere equally well to all coatings.For example,when the peel removal force of the tape (from the coating)used earlier by Task Group D01.23.10to establish precision of the method,by 3M No.710was examined with seven different electromagneticinterference/radio frequency interference (EMI/RFI)coatings,it was found that,while peel was indeed consistent for a given coating,the value varied by 25%between the highest and lowest ratings among coatings.Several factors that contribute to these differences include coating composition and topology:as a result,no single tape is likely to be suitable for testing all coatings.Further,the tape test does not give an absolute value for the force required for bond rupture,but serves only as an indicator that some minimum value for bond strength was met or exceeded (7,8).X1.6Procedural ProblemsX1.6.1The tape test is operator intensive.By design it was made as simple as possible to perform,and requires a mini-mum of specialized equipment and materials that must meet certain specifications.The accuracy and precision depend largely upon the skill of the operator and the operator’s ability to perform the test in a consistent manner.Key steps that directly reflect the importance of operator skill include the angle and rate of tape removal and the visual assessment of the tested sample.It is not unexpected that different operators might obtain different results (7,8).X1.6.2Peel Angle and Rate :The standard requires that the free end of the tape be removed rapidly at as close to a 180°angle as possible.If the peel angle and rate vary,the force required to remove the tape can change dramatically.Nearly linear increases were observed in peel force approaching 100%as peel angle was changed from 135to 180,and similar large differences can be expected in peel force as peel rate varies.These effects are related as they reflect certain rheological properties of the backing and adhesive that are molecular in origin.Variation in pull rate and peel angle can effect large differences in test values and must be minimized to assure reproducibility (9).X1.6.3Visual Assessment :The final step in the test is visual assessment of the coating removed from the specimen,which is subjective in nature,so that the coatings can vary among individuals evaluating the same specimen (9).X1.6.3.1Performance in the tape test is based on the amount of coating removed compared to a descriptive scale.The exposure of the substrate can be due to factors other than coating adhesion,including that arising from the requirement that the coating be cut (hence the synonym“cross-hatch adhesion test”).Justification for the cutting step is reasonable as cutting provides a free edge from which peeling can begin without having to overcome the cohesive strength of the coating layer.X1.6.3.2Cutting might be suitable for coatings applied to metal substrates,but for coatings applied to plastics or wood,the process can lead to a misleading indication of poor adhesion due to the unique interfacial zone.For coatings on soft substrates,issues include how deep should this cut penetrate,and is it possible to cut only to the interface?X1.6.3.3In general,if adhesion test panels are examined microscopically,it is often clearly evident that the coating removal results from substrate failure at or below the interface,and not from the adhesive failure

油漆附着力试验标准是对油漆附着力进行定量评定的方法，也是油漆行业中常用的检测标准之一。

一、试验标准的选择。

在进行油漆附着力试验时，首先需要选择适合的试验标准。

常用的油漆附着力试验标准有ASTM D3359、ISO 2409、GB/T 9286等。

不同的试验标准适用于不同的油漆类型和应用场景，选择合适的试验标准对于准确评定油漆附着力至关重要。

二、试验方法。

油漆附着力试验通常采用划格法、划十字法、拉伸法等不同的方法。

其中，划格法适用于平整的涂层表面，通过在涂层上划格并用胶带进行剥离来评定附着力；划十字法适用于粗糙或不规则的涂层表面，通过在涂层上划十字纹并用胶带进行剥离来评定附着力；拉伸法则通过在试验机上施加拉力来评定涂层与基材之间的结合强度。

选择合适的试验方法对于得到准确的附着力评定至关重要。

三、试验设备。

进行油漆附着力试验需要使用相应的试验设备，如划格仪、十字划格仪、拉伸试验机等。

这些设备需要经过校准和检验，确保其测试结果的准确性和可靠性。

四、试验操作。

在进行油漆附着力试验时，需要严格按照试验标准和试验方法进行操作。

在进行划格法和划十字法试验时，需要确保划痕的深度和间距符合标准要求，使用胶带进行剥离时要保持一定的速度和角度，以确保测试结果的准确性。

在进行拉伸法试验时，需要确保试验机的拉伸速度和加载方式符合标准要求，以得到可靠的测试结果。

五、试验结果的评定。

根据试验标准的要求，对试验结果进行评定。

通常情况下，根据涂层表面剥离的程度和面积大小来评定附着力等级，从而判断涂层的附着力是否符合要求。

六、结论。

油漆附着力试验是评定油漆涂层质量的重要手段，通过选择合适的试验标准、方法和设备，并严格按照标准要求进行操作和评定，可以得到准确可靠的试验结果。

这对于保证油漆涂层的质量，提高涂层的使用性能具有重要意义。

钢结构油漆涂层附着力的测试方法下面是本店铺给大家带来的关于钢结构油漆涂层附着力的测试方法相关内容，以供参考。

测定附着力的方法有：划圈法、划格法、拉开法、扭开法及美国ASTM中的划X法等数种，国家标准标准GB1720-89（79）规定了划圈法测定漆膜附着力的方法，而GB9286-88规定了采用划格法测定附着力，GB5210-85规定了采用拉开法测定涂层附着力的方法。

其中应用最简便的是划圈法测定漆膜附着力，现场最为常用的是划格法。

（1）、划圈法测定附着力划圈法所采用的附着力测定仪是按照划痕范围内的钢结构油漆的漆膜完整程度进行评定，以级表示。

是按照制备好的马口铁板固定在测定仪上，为确保划透漆膜，酌情添加砝码，按顺时针方向，以80-100r/min均匀摇动摇柄，以圆滚线划痕，标准圆长7.5cm，取出样板，评级。

实验中需要注意以下几点：（a）测定仪的针头必须保持锐利，否则无法分清1，2级的分别，应在测定前先用手指触摸感觉是否锋利，或在测定若干块试板后酌情理换。

（b）先试着刻划几圈，划痕应刚好划透漆膜，若未露底板，酌情添加砝码；但不要加得过多，以免加大阻力，磨损针头。

（c）评级时可以7级（最内层）开始评定，也可以1级（最外圈）评级，按顺序检查各部位的漆膜完整程度，如某一部位的格子有705以上完好，则认为该部位是完好的，否则认为坏损。

例如，部位1漆膜完好，附着力最佳，定为1级；部位1漆膜坏损而部位2完好的，附着力次之定为2级。

依据类推，7级附着力最差。

通常要求比较好的底漆附着力应达到1级，面漆的附着力可在2级左右。

（2）、划格法测定附着力划格法附着力测试标准主要有ASTMD3359、ISO-2409和GB9286-98。

其测试方法和描述基本相同，只是对于附着力级别的说明次序刚好相反。

ASTMD3359是5B-OB级由好到坏，而ISO-2409是0-5为由好到坏。

实验工具是划格测试器，它是具有6个切割面的多刀片切割器，切刀间隙1mm、2mm和3mm（刀头可以更换）。
