f）螺桿轉(zhuǎn)速和背壓：在滿足塑化質(zhì)量的前提下，應(yīng)盡量低，防止產(chǎn)生解降的可能；g）模具溫度：制品的冷卻好壞，對(duì)質(zhì)量影響極大，所以模溫一定要能精確控制其過程，有可能的話，模溫宜高一些好。5、其他方面的問題由于為要防上表面質(zhì)量惡化，一般注塑時(shí)盡量少用脫模劑；當(dāng)用回用料時(shí)不得大于20％。對(duì)于除PET外的制品都應(yīng)進(jìn)行后處理，以消除內(nèi)應(yīng)力，PMMA應(yīng)在70－80℃下熱風(fēng)循環(huán)干燥4小時(shí)；PC應(yīng)在清潔空氣、甘油、液體石臘等保護(hù)下加熱至110－135℃，時(shí)間按產(chǎn)品而定，**高需要10多小時(shí)。而PET必須經(jīng)過雙向拉伸的工序，才能得到良好機(jī)械性能。四、不同透明塑料的注塑成型工藝除了以上的共同問題，透明塑料亦各有一些工藝特性，現(xiàn)分述如下：1、PMMA的工藝特性PMMA粘度大，流動(dòng)性稍差，因此必須高料溫、高注射壓力注塑才行，其中注射溫度的影響大于注射壓力，但注射壓力提高，有利于改善產(chǎn)品的收縮率。PMMA注射溫度范圍較寬，熔融溫度為160℃，而分解溫度達(dá)270℃，因此料溫調(diào)節(jié)范圍寬，工藝性較好；故改善流動(dòng)性，可從注射溫度著手。但其沖擊性差，耐磨性不好，易劃花，易脆裂，故應(yīng)提高模溫，改善冷凝過程，以克服這些缺陷。2、PC的工藝特性PC粘度大，融料溫度高，流動(dòng)性差。常州優(yōu)惠的PC塑膠材料PC

由于塑料具有重量輕、韌性好、成型易、成本低等優(yōu)點(diǎn)，因此在現(xiàn)代工業(yè)和日用產(chǎn)品中，塑料被越來越多的用來代替玻璃，特別是在光學(xué)儀器和包裝工業(yè)的應(yīng)用方面發(fā)展尤為迅速。但是這往往要求所用的塑料必須具有透明性要好，耐磨性高，抗沖擊韌件好等特點(diǎn)，因此對(duì)塑料的成份，注塑整個(gè)過程的工藝、設(shè)備、模具等，都提出了很高的要求，以保證這些用于代替玻璃的塑料（以下簡稱透明塑料），表面質(zhì)量良好，從而達(dá)到使用的要求。目前市場上一般使用的透明塑料有聚甲基丙烯酸甲酯（即俗稱亞克力或有機(jī)玻璃，代號(hào)PMMA）、聚碳酸酯（代號(hào)PC）、聚對(duì)苯二甲酸乙二醇脂（代號(hào)PET）、透明尼龍、AS（丙烯睛一苯乙烯共聚物）、聚砜（代號(hào)PSF）等，其中我們接觸得**多的是PMMA、PC和PET三種塑料，由于篇幅有限，下面就以這三種塑料為例，討論透明塑料的特性和注塑工藝。一、透明塑料的性能透明塑料首先必須有高透明度，其次要有一定的強(qiáng)度和耐磨性，能抗沖擊，耐熱性要好，耐化學(xué)性要優(yōu)，吸水率要小，只有這樣才能在使用中，滿足透明度的要求而性能穩(wěn)定，PMMA、PC和PET的性能對(duì)比如下表所示。注：因品種繁多，這只是取平均值，實(shí)際不同品種數(shù)據(jù)有異。PET數(shù)據(jù)（機(jī)械方面）為經(jīng)拉伸后的數(shù)據(jù)。連云港化工原料PCGE</p><p
