聚氯乙烯工艺流程概述英文回答：Polyvinyl Chloride (PVC) Process Overview.Polyvinyl chloride (PVC) is a versatile thermoplastic material with a wide range of applications, including pipes, flooring, windows, and medical devices. The PVC production process involves several key steps:1. Raw Material Preparation: The raw materials for PVC production are ethylene and chlorine. Ethylene is typically obtained from natural gas or petroleum, while chlorine is extracted from salt.2. Ethylene Dichloride (EDC) Production: Ethylene and chlorine react in the presence of a catalyst to form ethylene dichloride (EDC). EDC is a volatile liquid that is purified by distillation.3. Vinyl Chloride Monomer (VCM) Production: EDC undergoes thermal cracking in a reactor to produce vinyl chloride monomer (VCM). VCM is a gas that is purified by distillation.4. PVC Polymerization: VCM is polymerized in a reactor to form PVC resin. The polymerization process involves the addition of free radicals to the VCM molecules, which causes them to bond together to form long chains.5. Additives and Compounding: Various additives, such as plasticizers, stabilizers, and fillers, are added to the PVC resin to improve its properties and performance. The resin is then compounded into pellets or powder form.6. Extrusion or Molding: The PVC compound is melted and extruded into various shapes, such as pipes, profiles, or sheets. Alternatively, it can be molded into specific products using injection molding or other techniques.7. Cooling and Finishing: The extruded or molded PVC is cooled and then undergoes finishing processes such ascutting, printing, or surface treatment to prepare it for its intended use.中文回答：聚氯乙烯工艺流程概述。

硬聚氯⼄烯（PVC－U）门窗异型材是由PVC、稳定剂、抗冲击改性剂、加⼯助剂、填料等按⼀定的配⽅配混、挤出成型的，PVC及助剂的选⽤对制品的性能有很⼤影响。

随着挤出硬PVC-U门窗异型材及塑料门窗⾏业的⾼速发展，相关的PVC及助剂⾏业也有了新的进展。

1　树脂及助剂的选择1.1　PVC⽣产PVC-U门窗异型材的，⼀般都使⽤悬浮法⽣产的疏松型PVC(SG-5)。

特别需要指出的是，⽣产PVC原料的⼄烯宜选⽤⽯油裂解法⽣产的，不⽤电⽯法⽣产的。

1.2　热稳定剂(1)热稳定剂的常⽤品种铅类热稳定剂　在铅类热稳定剂中，三盐基硫酸铅的热稳定性，应⽤最⼴;⼆盐基亚磷酸铅的热稳定性和耐初期着⾊性显著，同时赋予制品良好的耐候性，⽽⼆盐基硬脂酸铅和硬脂酸铅热稳定性稍差，但润滑性强，铅盐的缺点是有毒性，且外观易变⾊。

铅类热稳定剂的发展重点在于消除粉尘污染，开发复合型铅盐。

南京、温州、重庆是国内三⼤⽆尘复合盐⽣产基地，制造时⼤多是配合脂类润滑剂，产品有粒状、⽚状，可较好地解决粉尘污染问题。

⾦属皂类稳定剂　依其功能和机理分为主辅两类。

主⾦属皂以CdZn为主，辅助⾦属皂类稳定剂以Ba.Ca为主，主辅助⾦属皂配合使⽤，具有协同效应，具有代表性的是Ba-Cd，Ba-Zn和Ca-Zn。

国内常⽤的为Ba-Zn和Zn-Ca体系。

有机锡稳定剂　有机锡类稳定剂主要分为含硫有机锡和有机锡羧酸盐两类。

有机辅助稳定剂　有机辅助稳定剂通常与⾦属盐稳定剂并⽤，具有协同效应，主要包括亚磷酸脂、环氧化合物、多元醇、含硫辅助稳定剂、β－⼆酮辅助稳定剂。

稀⼟稳定剂　稀⼟稳定剂是我国新近开发出的新型热稳定剂，具有价廉、⽆毒、性能⾼、透明性好、储存稳定、耐候性优良等优点。

实际使⽤的稀⼟稳定剂通常是稀⼟与⾦属钙或锌的有机配混复合物。

(2)热稳定剂的选⽤不同国家和地区使⽤热稳定剂的种类差别较⼤。

pvc塑窗用异型材工艺流程PVC塑窗用异型材工艺流程呀，这可挺有趣的呢。

一、原料准备。

PVC树脂可是这个工艺流程里的主角哦。

它就像盖房子的砖头一样重要。

除了PVC 树脂，还得有稳定剂、润滑剂、填充剂、着色剂这些小配角呢。

稳定剂就像一个小保镖，防止PVC在加工过程中分解。

润滑剂就更有趣啦，它就像是在PVC分子之间抹上了一层油，让它们可以顺滑地动起来。

填充剂嘛，有点像往蛋糕里加面粉，能让这个异型材更有料。

着色剂呢，就像给这个型材穿上漂亮衣服，想要什么颜色就有什么颜色。

把这些原料按照一定的比例配好，就像搭配食材做一道美味佳肴一样，可不能乱了比例哦。

二、混合。

原料配好后就来到混合这个环节啦。

把它们一股脑儿地放进高速混合机里，这个混合机就像一个超级大的搅拌机。

一开动，里面就热闹起来啦，各种原料就开始欢快地跳起舞来，互相拥抱融合。

这个过程要把温度控制好，就像我们洗澡的时候调节水温一样，不能太热也不能太冷。

温度合适了，原料们才能更好地混合在一起，形成均匀的物料。

这个均匀的物料就像一团有魔法的面团，等着下一步的变身呢。

三、挤出。

混合好的物料就被送到挤出机这里啦。

挤出机就像一个神奇的大嘴巴，把物料慢慢吞进去。

在挤出机里，物料会被加热，就像被放在小火炉上烤一样。

这个加热过程让物料变得软软的，就像棉花糖一样。

然后，在螺杆的推动下，软软的物料就从模具里挤出来啦，这个时候就初步有了异型材的形状。

就好像从一个魔法模具里变出了一个小物件一样，是不是很神奇呢？四、定型冷却。

刚挤出来的异型材还是软软的呢，就像刚出锅的面条。

这时候就需要定型冷却啦。

有专门的定型装置，就像一个特制的小笼子，把异型材框住，让它保持住形状。

同时，冷却系统开始工作，冷风呼呼地吹着，就像给异型材扇扇子一样。

在这个过程中，异型材慢慢地变硬，形状就固定下来啦。

这就好比把一块软软的泥巴捏成一个形状后，让它晾干变硬一样。

五、牵引切割。

定型冷却后的异型材就可以被牵引着往前走啦。

pvc生态木生产工艺流程英文回答：PVC ecological wood production process involves several steps to transform PVC materials into eco-friendly wood-like products. Let me walk you through the process.1. Material Preparation: The first step is to gather the necessary materials, which include PVC resin, stabilizers, pigments, and additives. These materials are carefully selected to ensure the final product meets the desired quality and appearance.2. Mixing: The PVC resin is mixed with the stabilizers, pigments, and additives in a high-speed mixer. This process ensures that all the components are evenly distributed and well blended. The mixture is then heated to a specific temperature to achieve the desired consistency.3. Extrusion: The mixed PVC material is fed into anextruder, which is a machine that melts the material and pushes it through a die. The die is designed to give the PVC material the desired shape and size. As the material passes through the die, it is cooled down to solidify and maintain its shape.4. Embossing: After the extrusion process, the PVC material is embossed with a wood-like texture to enhanceits appearance and mimic the natural grain of real wood. This is achieved by using embossing rollers or plates that imprint the desired pattern onto the surface of the material.5. Cutting and Shaping: Once the PVC material is embossed, it is cut into the desired lengths and shapes. This can be done using a variety of cutting tools, such as saws or routers. The cut pieces are then further shaped and finished to achieve the final product.6. Surface Treatment: To enhance the durability and aesthetics of the PVC ecological wood, a surface treatment is applied. This can include processes such as sanding,polishing, or coating with protective layers. The surface treatment also helps to seal the material and protect it from moisture, UV rays, and other environmental factors.7. Quality Control: Throughout the production process, strict quality control measures are implemented to ensure that the PVC ecological wood meets the required standards. This includes checking for defects, testing the strengthand durability of the material, and verifying the color and texture consistency.中文回答：PVC生态木的生产工艺包括几个步骤，将PVC材料转化为环保的类似木材的产品。

塑制法的制备工艺流程英文回答：Plastic molding is a manufacturing process that involves shaping plastic materials into specific forms or shapes. It is a widely used method in various industries, such as automotive, electronics, and consumer goods. The process typically involves the following steps:1. Design and Prototyping: The first step in plastic molding is to create a design or prototype of the desired product. This can be done using computer-aided design (CAD) software or by creating a physical prototype using 3D printing or other methods.For example, when designing a new smartphone case, I would use CAD software to create a 3D model of the case, including all the necessary features and dimensions.2. Mold Creation: Once the design is finalized, a moldis created based on the desired shape of the product. The mold is usually made of steel or aluminum and consists of two halves, the cavity and the core. The mold is precision-machined to ensure the accuracy of the final product.To continue with the smartphone case example, I would work with a mold maker to create a mold that matches the design of the case. The mold would have the shape of the case, including any intricate details or textures.3. Material Preparation: The next step is to prepare the plastic material for molding. This involves selecting the appropriate type of plastic resin and melting it down to a liquid state. The plastic resin can be in the form of pellets or granules.For instance, if I am manufacturing the smartphone case using ABS plastic, I would need to melt down ABS resin pellets in a specialized machine called an injection molding machine.4. Injection Molding: Once the plastic material ismelted, it is injected into the mold cavity under high pressure. The molten plastic fills the entire cavity and takes on the shape of the mold. After a cooling period, the plastic solidifies and can be ejected from the mold.In the case of the smartphone case, I would place the melted ABS plastic into the injection molding machine, which would then inject the plastic into the mold cavity. The plastic would cool and solidify, and I would then remove the finished smartphone case from the mold.5. Finishing and Assembly: After the plastic parts are ejected from the mold, they may require additionalfinishing processes, such as trimming excess material, removing any imperfections, or adding surface treatments like painting or printing. The finished plastic parts can then be assembled with other components to create the final product.To complete the smartphone case, I would trim any excess plastic, remove any imperfections, and add any necessary surface treatments, such as painting or applyinga logo. Finally, I would assemble the plastic case with other components, such as buttons or a screen protector.中文回答：塑制法是一种将塑料材料塑造成特定形状的制造工艺。

塑料异型材挤出生产的工艺过程一、塑料异型材挤出生产的工艺过程塑料异型材最终挤出制品生产的一般过程如下：配方设计购料-→主辅料配混(混料机)购料-→挤出加工(挤出机)连续-→冷却定型(模具、定型台)连续-→牵引计长、切割(牵引切割机)连续-→翻料检验、入库贮运-→组装、焊接等(组装、焊接等设备)检验-→贮运最终用户制品在以上生产工艺过程中，塑料异型材挤出生产工艺只包括配方设计、主辅料的配混、挤出加工、冷却定型、牵引计长切割及贴膜打印与翻料过程。

挤出生产的异型材最终还需组装、加工、焊接等若干专用工序处理才能作为门窗等最终制品进行应用。

因而从异型材的应用角度而言，塑料异型材的挤出生产类似于木制品的半成品材料生产(伐木后对木材的锯解保存处理)。

从以上异型材生产工艺的一般要求同样也说明了对异型材生产装备的功能要求和技术路线，即在配方设计(反复实验)和物料配混工序完成后，异型材挤出装备必须连续和全自动的完成上料、塑化、排气、挤出、成型、冷却定型、牵引、计长切割、堆料的全过程。

而要连续高效的完成每一步工序并最终生产出合乎标准的异型材，其中涉及的技术关联程度是相当高的，装备技术与加工对象具体工艺要求的科学匹配往往成为目前挤出技术工作中最具体实践意义的工作。

与切削加工无机金属材料的机床不同，作为对有机高分子聚合物(塑料异型材)成型加工的异型材装备，其异型材的性能特性和成型精度不仅与装备精度有关，更与加工对象的物性和加工的各种历程(热历程、流变历程、相变历程等)及其匹配程度有关。

因此，从装备技术的创新发展和异型材生产工艺的更深入研究两方面的提高将推动异型材挤出技术向更高层次飞跃。

二、塑料异型材挤出技术系统塑料异型材挤出技术包含三大相互关联密切相关的关键技术系统，即配方(工艺)设计与原料配混技术、挤出设备技术、挤出模具技术。

这三大技术系统有机地结合在一起，构成塑料异型材挤出技术的核心。

(一)配方(工艺)设计与原料配混技术系统配方(工艺)设计是对最终制品起决定性作用的技术因素之一，配方设计的好坏关系到挤出生产的稳定性及制品是否合格。

塑料成型工艺流程及条件介绍（中英文）塑料模具成型技术流程及参数介绍Molding technique procedure and parameter introduction 第一節成型工艺Section 1 molding technique.1.成型工艺参数类型Sorts of molding parameter.(1). 注塑参数Injection parameter.a.注射量Injection rate.b.计量行程Screw back positionc.余料量Cushiond.防诞量Sucking back ratee.螺杆转速Screw speedf.塑化量Plastic0 rateg.预塑背压Screw back pressureh.注射压力和保压压力Injection pressure and holding pressurei.注射速度Injection speed(2)合模参数Clamping parameterClamping forceb.合模速度Clamping speedc.合模行程.Clamping stroked.开模力Opening forcee.开模速度Opening speedf.开模行程Opening positiong.顶出压力Ejector advance pressureh.顶出速度Ejector advance speedi.顶出行程Ejector advance position2.温控参数Temperature parametera.烘料温度Dry resin material temperatureb.料管与喷嘴温度Cylinder temperature and nozzle temperature c.模具温度Mold temperatured.油温Oil temperature3.成型周期Molding cycleCycle timeb.冷却时间Cool timec.注射时间Injection timed.保压时间Holding pressure timee.塑化时间Plant timef.顶出及停留时间Knocking out and delay timeg.低压保护时间Mold protect time成型工艺参数的设定须根据产品的不同设置.Molding technique parameter setting differs depending on type of product第二节成型条件设定Section 2 Molding parameter Setting按成型步骤:可分为开锁模,加热,射出,顶出四个过程.Molding steps: mold opening/closing, heating injection and knocking out.开锁模条件:Mold opening parameter:快速段中速度低压高压速度High-speedmid-speedLow pressure high pressure speed锁模条件设定:Mold closing parameter setting1锁模一般分: 快速→中速→低压→高压Mold closing: high-speed →low-speed →low pressure→high pressure2.快锁模一般按模具情况分,如果是平面二板模具,快速锁模段可用较快速度,甚至于用到特快,当用到一般快速时,速度设到55-75%,完全平面模可设定到80-90%,如果用到特快就只能设定在45-55%,压力则可设定于50-75%,位置段视产品的深浅(或长短)不同,一般是开模宽度的1/3.In high-speed section, Mold closing speed depends on type of mold. For two –plate mold it can set quick andeven especially quick usually, it set speed within 55-75%. For full-plate mold it set speed within80-90%while using especially high speed it set speed within 45-55% and pressure within 50-75% position distancesetting differs depending on the volume of product and usually it can be set 1/3 of mold opening position.3.中速段,在快速段结束后即转换成中速,中速的位置一般是到模板(包括三板模,二板模)合在一块为止,具体长度应视模板板间隔, 速度一般设置在30%-50%间,压力则是20%-45%间.In mid-speed section: Mold closing speed changes into mid-speed after high-speed section finish. Mid-speed start position is where two plates meet (include three-plate mold and two-plate mold ) Distance of mid-speed is up to distance of two plates plate it speed within 30-50% and pressure 20-45%.4.低压设定,低速设定一般是在模板接触的一瞬间,具体位置就设在机台显示屏显示的一瞬间的数字为准,这个数字一般是以这点为标准, ,即于此点则起不了高压,高于此点则大,轻易起高压.设定的速度一般是15%-25%,视乎不同机种而定,压力一般设定于1-2%, 有些机则可设于5-15%,也是视乎不同机种不同.Low-pressure section: Mold closing sets low-pressure when plates meeting. This position is set to the data ofmachine screen on this time. This point is the gage of the data. Data lower the point there is no high-pressure.Data higher the point there is high-pressure easily. It set speed within 15-25% and pressure within 1-2%depending on type within 1-2% depending on type of injection molding machine.5.高压设定,按一般机台而言,高压位置机台在出厂时都已作了设定,相对来讲,是不可以随便更改的,比如震雄机在50P.速度相对低压略高,大约在30-35%左右,而压力则视乎模具而定,可在55-85%中取,比如完全平面之新模,模具排气良好,甚至于设在55%即可,如果是滑块较多,原来生产时毛边也较多,甚至于可设在90%还略显不足.High-pressure section: T o normal injection molding machine, high-pressure position had been set beforethey were sent to customer. It can not be modified. For example high-pressure position of CHENHSONG machine is 50P.The speed of high-pressure section is about 30-35% and higher than that of low-pressure.The pressure is up to mold, it can set within 55-85% For full-plate mold, it’s eject air well,it can set pressure 55% .If mold has a lot of slides and flash rate high in production, pressure can set 90%.二.熔胶段工艺Plastic Technique1.再复杂的熔胶旋转过程最多不会超过三段,因为熔胶本身就是存在于把胶熔进料筒的过程,如果原料粘度大,熔胶压力则大,但速度则应取决于原料的分解温度,熔胶速度越快,原料中的剪切力则会越大,料管温度则越高,局部原料产生分解的可能性则会越大, 故一般熔胶会采用中速为宜,如45%-75%,熔胶同时会碰到一个比较重要的环节,那就是背压的使用,产品精度要求越大,背压的使用则更大,背压可使原料分子间结构更紧密,成型出的产品则尺寸更稳定,外观越好.当然,背压太大,则会产生流涎,所以背压的使用又应考虙到其它原因.Plastic should lower 3 steps, because plastic is a step to add melt resin material to cyclinder ,Higher stick of resin material ,higher screw back pressure. Screw speed differs dependingon decomposing temperature of resin material ,Higher screw speed ,Higher trim force of resin,higher cyclinder temperature. Some resin material may decomposes so it set screw speed in mid-speed such as 45-75%, In plastic step setting screw back pressure is very important, Higher screw back pressure ,higher quality of product screw back pressure make resin structure order,Molding product is beautiful and volume stable. But ,it maybe flow if screw back pressure too high .So all factors should be considered when using screw back pressure.2.熔胶过程还有一个比较重要的环节,那就是松退,松退分前松退和后松退,其作用一般是为了防止流涎和抽丝,设定值速度和压力都在20%-50%间,设定的行程一般在2-5cm间,太长的行程可能会使料筒里面贮存空气,导致下一模出现不期望的气泡.In plastic step sucking back is very important too. Suckingback include front sucking backand back sucking back It setting sucking back to prevent flow and line.It sets sucking back speed and pressure within 20-50% and distance within 2-5cm.TOO long distance make cyclinder reserve air and cause bubble at next molding.顶出的工艺设定knocking out technique setting产品经冷却定型后则有一个开模的过程,开模基本上是合模的反过程.开模的未段则有一个慢速设置,开模完成后,产品必须顶出的过程.There is a mold opening step after product cooling taking shape.Mold opening is a reverse step of mold closing. The last step of mold opening speed set slow.Product should be knocked out after mold opened.一.顶前:Knocking out顶前最好分两个阶级,第一阶可分为中压慢速,即是把产品轻轻顶出一部分,然后是中压中速顶,中压中速一般指的是35%-55%, 而低速则有可能低到5%,这需视产品不同而言,顶出行程设定是顶出长度稍比产品垂直深度大1-2cm即可.Knocking out includes two steps, Step1 section setting mid-speed,knocks product out partly step2 section setting mid-pressure and mid-speed .Depending on different product, mid-pressure and mid-speed sets within 35-55% but low-speed can set 5%.Distance of knocking out longer 1-2cm than the verticalthickness of product.二.退针Back顶退包括两个过程与顶落的过程基本一致,顶退的终点应预留1-3cm的空间,以保护顶针油管不被顶坏.The same as knocking out, ejector back includes 2 steps. To protect the ejector oil jar,it should make a 1-3mm distance in the ending point of ejector back.三.顶针方式还包括一个多次顶,单次顶及顶针停留的选择,机械手取产品,脱模顺利的情况都采取多项,为了顶针油缸寿命的延长,多次顶就以不超过三次为宜,顶针停留一般用在顶针带着产品退回有可能对增品产生损伤的模具,同时为配合机械手使用,有时也需要较短的顶针停留.The way of knocking out includes knocking out once, Knocking out repeat and ejector delay.Take product by manipulator or take product easy, it should select knocking out once.To longer the work time of ejector oiljar, times of knocking out lower 3 times.Ejector delay used when product will be damaged if ejector back or suitmanipulator.成型时间的设定Molding time setting在保证产品质量的前提下,周期时间是越短越好,周期时间又包括如下几项:射胶时间,保压时间,熔胶时间,冷却时间,顶出时间,锁模低压时间,甚至乎关系到时间因素的还有还开模与锁模,及顶出的快慢.Cycle time should shorter on condition that product quality well. Cycle time includes: injection time ,holding pressure time, plastic time, cure time, knocking out time and mold protect time.Even mold opening closing sopeed and knocking out speed affect cycle.1. 射胶时间包含保压时间,一般看起来,射胶时间越长,产品越饱和,但我们在讲求质量时,同时也须考虑产能更何况,射胶时间过长,有可能会造成产品过于饱满而导致粘模顶的变形呎寸偏大等一系列问题,故我们在设置射胶时间时应综合考虑,尽量在合乎质量要求时缩短射胶时间.Injection time consists holding pressure time. Longer injection time, fuller product,we should consider production quantity when we suit for quality. If injection time too long,it may cause a series of defects suck as flash strain. So all sorts of factors should be considered,injection time should be shout if quality suit for requirement.2. 熔胶时间的长短取决于熔胶速度设定的快慢,背压设定的大小,但有一点,熔胶时间控制的长短一定要比冷却时间短.Plastic time depends on plastic speed and screw back pressure, but plastic time must shorter than cure time.3. 冷却时间:冷却时间的长短直接影响到成型的周期,冷却时间越长,成型时间就越长,造成产能就越低,故我们在设定高压冷却时间时,只要能保证到产品成型顺利,不会直接影响到变形等问题,设定的时间也是越短越好.Cure time: Cure time affects molding cycle. Longer cure time, longer molding cycle, lower production quantity.So it sets cure time short on condition that product moldingsucced and can’t deformation..4. 在大量使用机械手的塑胶公司,我们的顶出时间一般是与机械手配合为宜,全自动使用机械手时顶出停留时间一般保持1.5-2秒, 半自动生产,如因顶针退回会导致产品掉落或卡紧,而取不下产品,停留时间则应保持5秒左右.In PCE company, for using manipulator in abundence , knocking out time suits manipulator,Knocking out delay keeps 1.5-2 second when using manipulator full-manipulator,knocking out delay keeps about 5 second when using manipulator semi-manipulator and product will fallor can’t be taken off if ejector back.5. 低压保护时间对保护我们人身安全,模具安全起很大作用,配合好模具低压位置和低压压力的调整,低压保护的时间应取1-3秒,保护时间越短,可能造成的危害则越小.Low-pressure protect is very important for safety and protect mold, Mold protect time should adjustwithin 1-3 second suit low pressure and position of mold protect, shorter protect time, make damaged.。
