分为四个等级分别为Sa1、Sa2、Sa2.5、Sa3，具体如下：Sa1级——相当于美国SSPC—SP7级。
采用一般简单的手工刷除、砂布打磨方法，这是四种清洁度中度最低的一级，对涂层的保护仅仅略好于未采用处理的工件。
Sa1级处理的技术标准：工件表面应不可见油污、油脂、残留氧化皮、锈斑、和残留油漆等污物。
Sa1级也叫做手工刷除清理级（或清扫级）。
Sa2级——相当于美国SSPC—SP6级。
采用喷砂清理方法，这是喷砂处理中最低的一级，即一般的要求，但对于涂层的保护要比手工刷除清理要提高许多。
Sa2级处理的技术标准：工件表面应不可见油腻、污垢、氧化皮、锈皮、油漆、氧化物、腐蚀物、和其它外来物质（疵点除外），但疵点限定为不超过每平方米表面的33%，可包括轻微阴影；少量因疵点、锈蚀引起的轻微脱色；氧化皮及油漆疵点。
如果工件原表面有凹痕，则轻微的锈蚀和油漆还会残留在凹痕底部。
Sa2级也叫商品清理级（或工业级）。
Sa2.5级——是工业上普遍使用的并可以作为验收技术要求及标准的级别。
Sa2.5级也叫近白清理级（近白级或出白级）。
Sa2.5级处理的技术标准：同Sa2要求前半部一样，但疵点限定为不超过每平方米表面的5%，可包括轻微暗影；少量因疵点、锈蚀引起的轻微脱色；氧化皮及油漆疵点。
Sa3级——级相当于美国SSPC—SP5级，是工业上的最高处理级别，也叫作白色清理级（或白色级）。
Sa3级处理的技术标准：与Sa2.5级一样，但5%的阴影、疵点、锈蚀等疵点不得存在了。
注意：保护层法在金属表面覆盖保护层，使金属制品与周围腐蚀介质隔离，从而防止腐蚀。
如：（1）在钢铁制件表面涂上机油、凡士林、油漆或覆盖搪瓷、塑料等耐腐蚀的非金属材料。
（2）用电镀、热镀、喷镀等方法，在钢铁表面镀上一层不易被腐蚀的金属，如锌、锡、铬、镍等。
这些金属常因氧化而形成一层致密的氧化物薄膜，从而阻挡水和空气等对钢铁的腐蚀。
（3）用化学方法使钢铁表面生成一层细密稳定的氧化膜。

环氧磷酸锌底漆施工方法
以下就是环氧磷酸锌底漆施工方法，仅供参考：
1.基面处理：施工前需要将被施工的基面处理干净，如果使用在钢材基面，可以采取喷砂的方式处理达到Sa
2.5级别，有油污的部位使用专用试剂处理干净，清水冲洗掉杂质，干净干燥后即可上漆使用，避免有残渣影响油漆附着。
2.油漆混合：双组份的油漆在使用上漆前，需要将其两个组份进行混合，根据施工面积大小确定使用量，避免不必要的浪费，先将成分一加入到搅拌容器中，混合，颜色一致后在常温下熟化10-20min后即可上漆使用。
3.施工方式：施工上漆的方式有多种，可以选择喷涂，刷涂以及滚涂的施工方式，在上漆前，需要将油漆的粘度调节适宜，这样比较容易产生均匀平整的涂层，使用哪一种施工方式都要注意不要有漏涂现象，这样能够保障油漆的性能体现。

SSPC-Paint 20November 1, 1982Editorial Changes August 1, 1991 SSPC: The Society for Protective CoatingsPAINT SPECIFICATION NO. 20Zinc-Rich Primers (Type I, "Inorganic," and Type II, "Organic")1. Scope1.1 This specification covers one group of highly pig-mented zinc-rich coatings that are uniquely defined by their capability of galvanically protecting steel exposed at discontinuities such as narrow scratches and holidays. While the major pigment component in this coating is zinc dust, the vehicle may be inorganic (Type I) or organic (Type II).1.2 This specification does not cover all types of zinc-rich coatings. For example, it is not a straight performance specification, nor does it pertain to extended zinc-rich coatings, nor to weldable pre-fabrication zinc-rich primers, which are applied at low thicknesses (approximately one mil [25 micrometers] or less). Further information regarding these and other zinc-rich coatings can be found in SSPC-PS Guide 12.00, "Guide to Zinc-Rich Painting Systems," and other SSPC specifications.1.3 This specification defines the minimum composi-tional and laboratory performance requirements for identi-fying a group of zinc-rich paints. It is to be used in conjunc-tion with SSPC-PS Guide 12.00, "Guide to Zinc-Rich Paint-ing Systems"; and with other SSPC specifications covering surface preparation, applications, thickness, inspection, and safety.1.4 This primer, when applied over properly prepared steel surfaces, is suitable for use on parts or structures exposed in Environmental Zones 1A (interior, normally dry), 1B (exterior, normally dry), 2A (frequently wet by fresh water), and 2C (fresh water immersion). They may be used in Environmental Zones 2B (frequently wet by salt water), 2D (salt water immersion), 3A (chemical, acidic), and 3C (chemical, alkaline) with proper topcoating.1.5 This primer is intended for application by spray and is to be applied in accordance with SSPC-PA 1, "Shop, Field, and Maintenance Painting of Steel."2. Description2.1 The zinc-rich coatings described in this specifica-tion consist of zinc dust, an organic or inorganic vehicle, and selected additives as required.2.2 PIGMENTATION:2.2.1 The major pigment component in these coatings is zinc dust of the type described in ASTM D 520, "Zinc Dust (Metallic Zinc Powder)."2.2.2 Other pigment components may include curing aids, tinting colors, suspension and pot life control agents, but should constitute only a minor part of the total pigment portion so as not to detract from the ability of these coatings to protect galvanically.2.3 VEHICLE TYPES:2.3.1 Type l-A, inorganic post-curing vehicles—water soluble, include alkali metal silicates, phosphates, and modifications thereof which must be subsequently cured by application of heat or a solution of a curing compound.2.3.2 Type l-B, inorganic self-curing vehicles—water reducible, include water soluble alkali metal silicates, quarternary ammonium silicates, phosphates, and modifi-cations thereof. These coatings cure by crystallization after evaporation of water from the coating.2.3.3 Type l-C, inorganic self-curing vehicles—solvent reducible, include titanates, organic silicates, and poly-meric modifications of these silicates. These systems are dependent upon moisture in the atmosphere to complete hydrolysis, forming the polysilicate.2.3.4Type II, organic vehicles—include phenoxies, catalyzed epoxies, urethanes, chlorinated rubbers, sty-renes, silicones, vinyls, and other suitable resinous bind-ers. The organic vehicles covered by this specification may be chemically cured or may dry by solvent evaporation. Under certain conditions heat may be used to facilitate or accelerate hardening.3. Reference Standards3.1 The standards referenced in this specification are listed in Sections 3.4 through 3.7 and form a part of this specification.3.2The latest issue, revision, or amendment of the referenced standards in effect on the date of invitation to bid shall govern unless otherwise specified.SSPC-Paint 20November 1, 1982Editorial Changes August 1, 19913.3 If there is a conflict between the requirements of any of the cited reference standards and this specification, the requirements of this specification shall prevail.3.4 SSPC STANDARDS AND JOINT STANDARDS:PA 1Shop, Field, and MaintenancePainting of SteelPA Guide 3 A Guide to Safety in Paint Appli-cationPS 12.01One-Coat Zinc-Rich PaintingSystemPS Guide 12.00Guide to Zinc-Rich Coating Sys-temsSP 5/NACE No. 1White Metal Blast Cleaning3.5 AMERICAN SOCIETY FOR TESTING AND MA-TERIALS (ASTM) STANDARDS:A 36Specification for Carbon Structural SteelB 117Practice for Operating Salt Spray (Fog)ApparatusD 56Test Method for Flash Point by Tag ClosedTesterD 185Test Methods for Coarse Particles in Pig-ments, Pastes, and PaintsD 521Test Methods for Chemical Analysis ofZinc Dust (Metallic Zinc Powder)D 562Test Method for Consistency of PaintsUsing the Stormer ViscometerD 1200Test Method for Viscosity by Ford Viscos-ity CupD 1308Test Method for Effect of HouseholdChemicals on Clear and Pigmented Or-ganic FinishesD 2369Test Method for Volatile Content of Coat-ingsD 2371Test Method for Pigment Content of Sol-vent-Reducible PaintsD 3359Test Methods for Measuring Adhesion byTape TestD 3925Practice for Sampling Liquid Paints andRelated Pigmented Coatings3.6 FEDERAL STANDARDS:PPP-P-1892Paint, Varnish, Lacquer, andRelated Materials; Packaging,Packing and Marking ofFED-STD-141 Paint, Varnish, Lacquer and Related Materials: Methods of Inspection, Sampling and TestingMethod 4331Spraying PropertiesMethod 4541Working Properties and Appear-ance of Dried Film3.7 AMERICAN NATIONAL STANDARDS INSTITUTE (ANSI) STANDARD:Z129.1Hazardous Industrial Chemicals—Precautionary Labeling4. Composition4.1 The paint shall conform to the composition (analy-sis) requirements of Table 1. This table defines the mini-mum compositional requirements of these zinc-rich paints without specifying the vehicle.5. Qualitative Requirements5.1 The paint shall meet the qualitative requirements Sections 5.2 through 5.10.TABLE 1REQUIREMENTSMINIMUM REQUIREMENTS STANDARDSCHARACTERISTISCS1 Inorganic Organic ASTMTotal Solids, % by weight of paint78 70 D 2369 Pigment, % by weight of total solids85 83 D 2371Total zinc dust2, % by weight of pigment87 93 D 521Total zinc dust2, % by weight of total solids74 77 —1The minimum composition requirements of a zinc-rich paint is controversial. It is recognized that zinc-rich primers containing extenders, although having less total zinc dust than specified, may be able to pass all other requirements of this specification. However, these compositional requirements arenecessary, as certain non-zinc containing coatings may also be able to pass all other requirements of this specification.2Zinc dust shall meet ASTM D 521.SSPC-Paint 20November 1, 1982 Editorial Changes August 1, 19915.2 MIXING: The raw materials of the liquid portion of either the inorganic or organic multi-component paints shall be mixed and dispersed as required to produce a product which is uniform, stable, free from grit, and conforms to the requirements of this specification.The pigment portion of multi-component paints, prior to mixing, shall be dry and loosely packed.The ready-mixed paint shall be capable of being bro-ken up with a paddle to a smooth, uniform consistency and shall not liver, thicken, curdle, gel, or hard settle, nor show any other objectionable properties in a mixed, freshly opened container.After mixing, all types of coarse particles and skins as residue retained on a standard 60 mesh screen shall be no more than 0.5% by weight of total paint, regardless of type, in accordance with ASTM D 185.5.3 POT LIFE: The pot life of the zinc-rich paint, when mixed and ready for application in accordance with manufacturer's instructions, shall be a minimum of four hours at 70°F (2°C) and 50% relative humidity. Although physical properties (viscosity, etc.) may not change, loss of pot life is indicated by lack of adhesion when tested in accordance with Section 5.8. Good practice has been that multicomponent zinc-rich paint be used within 12 hours after mixing.5.4 STORAGE LIFE: Neither the vehicle of the multi-component paint nor the ready-mixed paint shall show thickening, curdling, gelling, gassing, or hard caking after being stored unmixed for six months from date of delivery in a tightly covered unopened container at a temperature of 50-90°F (10-32°C).5.5 WORKING PROPERTIES: The mixed paint shall spray easily, and show no streaking, running, sagging, or other objectionable features when tested in accordance with FED-STD-141, Methods 4331 and 4541.5.6 TEST PANEL PREPARATION: Steel test panels (ASTM A 36 hot rolled steel or equivalent), measuring 4"x 6"x 1/16" (10 cm x 15 cm x 1.5 mm) or greater, shall be white metal blast cleaned (SSPC-SP 5) with a nominal anchor profile from 1.5-3.5 mils (38-88 micrometers) (Section 10.4) and coated with the zinc-rich paint. The panels shall be blast cleaned and coated on both sides and all edges. The paint shall be spray applied and hardened in accordance with manufacturer's recommendations. The dry film thick-ness shall be 2.5-3.5 mils (64-88 micrometers) unless otherwise designated. Prior to any exposure testing, all panels shall be aged for 14 days at 75-79°F (24-26°C) and 45-55% relative humidity.5.7 MUDCRACKING: The coating when applied in accordance with Section 5.6 to a five to six mil (125-150 micrometers) dry film thickness, shall show no mudcracking when viewed under 10X magnifications.5.8 ADHESION: The coating when applied and hard-ened in accordance with Section 5.6, shall adhere to the steel substrate when subjected to the "Cross-Cut/Tape Test" (ASTM D 3359, Method B).There shall be no separation of the paint film, or delamination of an entire square. Spalling loss of adhesion around the perimeter due to cutting of each square is acceptable.Adhesion rating should be no less than 4B grading when evaluated according to the procedure of ASTM D 3359, Method B.5.9 SALT FOG RESISTANCE:The coating, when applied and hardened in accordance with Section 5.6 and scribed as described below, shall pass 1,000 hours mini-mum exposure to salt fog (ASTM B 117) without any blistering or rusting of the coated portion, with no undercut-ting from the scribe. (Slight rusting in the scribe mark will be permissible and resulting staining should be ignored.) Strips 1/4" (6 mm) wide along the edges of the panel may be ignored. Testing shall be done in triplicate.The scribe mark shall be centrally positioned in the lower half of the panel and shall consist of an "X" comprising the diagonals of a 2" x 2" (5 x 5 cm) square. To insure proper positioning, cleanliness and depth of scribe mark, a tem-plate and scriber or cutting tool having a cutting edge at least 1 /32" (0.8 mm) wide shall be used. The operator shall bear down hard and go over each arm of the cut twice to insure a clean scribe of sufficient depth to remove any zinc particles from the scribe and to expose clean steel.5.10 ADDITIONAL RESISTANCE TESTS: Additional screening qualification tests may be required by the user (Section 10.8).6. Material Quality Assurance6.1 In order to determine the acceptability of a lot or batch of a qualified product, the paint shall meet the re-quirements of Sections 6.2 through 6.4.6.2 Viscosity of the mixed paint shall be determined in accordance with ASTM D 562. Variance shall be within ±5 Krebs Units or equivalent units of another viscometer of the viscosity of the previously qualified paint.For viscosities lower than 55 K.U., a 4 Ford Cup shall be used in accordance with ASTM D 1200. Variations shall be within ±5 seconds of the viscosity of the previously qualified paint.6.3Weight per gallon of the mixed paint shall be determined in accordance with ASTM D 1475. Variance shall be within ±0.4 pounds (180 g) of the nominal weight per gallon of the previously qualified paint.SSPC-Paint 20November 1, 1982Editorial Changes August 1, 19916.4 Solids percent by weight of the mixed paint shall be determined in accordance with ASTM D 2369. The percent solids by weight shall be no less than that specified in Table 1. Variance shall be within ±2% of the nominal percent solids by weight of the previously qualified paint.6.5 Other tests may be used to determine the accept-ability of a lot or batch of a qualified product at the discretion of the user.7. Labeling7.1 Refer to ANSI Standard Z129.1, "Industrial Hazard-ous Chemicals—Precautionary Labeling." Other guidelines can be found in the National Paint and Coating Association (NPCA) "Paint Industry Labeling Guide."7.2 MARKING OF CONTAINER: Each container shall be legibly marked with the following information:Name: Zinc-Rich PrimerSpecification: SSPC-Paint 20, TypeComponent:Color:Lot Number:Stock Number:Date of Manufacture:Quantity of Paint in Container:Information and Warnings as may be required byFederal and State Laws:Manufacturer's Name and Address:7.3 PACKAGING: The pigment portion of multicompo-nent zinc-rich paints shall be packaged separately to be mixed with the liquid portion shortly before use. Each container of liquid shall be packaged and labeled in accor-dance with the requirements of Federal Specification PPP-P-1892 and shall include directions showing correct propor-tions of liquid to pigment along with necessary mixing instructions. The packaging of single component zinc-rich paints, Types I and II, shall also comply with the above Federal Specification.7.4 DIRECTIONS FOR USE: The manufacturer shall supply complete instructions covering uses, surface prepa-ration, mixing, thinning, application method, application conditions, pot life, wet and dry film thicknesses, tempera-ture and humidity limitations, drying times, etc. with each container of paint.8.

The user of this specification, as well as the user of all products or practices described herein, is responsible for instituting appropriate health and safety practices and for insuring compliance with all governmental regulations.10. NotesNotes are not requirements of this specification.10.1 The procurement documents should establish the responsibility for samples, testing, and any required affida-vit certifying full compliance with the specification.10.2 COVERAGE: Except for special cases, most zinc-rich primers are formulated to apply at nominal dry film thicknesses of 2.5-3.5 mils (64-88 micrometers). In actual practice a coverage of 150 to 300 square feet per gallon (3.7- 7.4 square meters per liter) will be expected over flat blast cleaned surfaces.10.3 FLASH POINT:The minimum flash point, as determined by the Tag closed cup (ASTM D 56) should be "none" for inorganic water base zinc-rich coatings, and a minimum of 55°F (13°C) for solvent base inorganic zincs (Type l-C) and 50°F (10°C) for organic zincs (Type II).SSPC-Paint 20November 1, 1982 Editorial Changes August 1, 1991Specific applications, such as the interior of tanks, holds, and other confined spaces normally require a minimum flash point of 100°F (38°C).10.4A Surface Profile Comparator is available from SSPC for sand, grit, and shot blast cleaned surfaces. Alternatively, replica tape, depth micrometer, stylus, micro-scopic measurement methods, or other suitable techniques may be used.10.5 Inorganic zinc-rich paints Types l-A and l-B should not be stored at temperatures below 40°F (4°C). Further-more, storage of all zinc-rich paints above 90°F (32°C) should be avoided.10.6Inorganic zinc-rich primers (Types l-A and l-B) should not be applied at surface temperatures below 40°F (4°C). Type l-C should not be applied at relative humidities below 50%, without specific instructions from the paint manufacturer.10.7Multiple component zinc-rich paints should be applied within four hours after mixing and should be con-tinuously agitated during application.10.8 ADDITIONAL RESISTANCE TESTS: Because of the diversity of potential service environments, this specifi-cation may require the zinc-rich primer be further exposed and qualified by at least one additional test relating to the intended exposure. For example, if the intended service is a petroleum tanker cargo hold which is ballasted with sea water, appropriate test requirements other than those al-ready specified might be:•Salt Water Immersion (1,000 hours) ASTM D 1308•Oil Immersion (1,000 hours) ASTM D 1308 or a cycling combination of bothComparative testing of all candidate zinc-rich primers will be more meaningful than individual testing of each primer.Standard tests which may be useful for further qualifi-cation are available from a number of organizations, includ-ing ASTM, U.S. Government Federal Specifications (TT-P; MIL-P, etc.), Federal Test Method Standards (141), and Canadian Government Specifications Board. A partial list-ing of public zinc-rich specifications requiring qualification testing is presented in the Notes of SSPC-PS Guide 12.00, "Guide for Selecting Zinc-Rich Painting Systems."However, it should be emphasized that a well designed non-standard test may often provide more meaningful infor-mation for a given service condition than one or more standard tests.SSPC规范－油漆20美国钢结构涂装协会标准1总则1.1技术规范涵盖的两个种类的富锌漆，只有一个定义：在露底和细小擦损部位涂层漆膜不连续的情况下也能保护裸露金属。
