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(lái)越多的用來(lái)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(guò)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(jiǎn)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(chǎng)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)。泰州**PC**奇美PC

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(guò)程，有可能的話，模溫宜高一些好。5、其他方面的問(wèn)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(guò)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(wèn)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(guò)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。</p><p> 其次由于透明塑料大多熔點(diǎn)高、流動(dòng)性差，因此為保證產(chǎn)品的表面質(zhì)量，往往要在較高溫度下進(jìn)行注塑，注射壓力、注射速度等工藝參數(shù)也均需作細(xì)微調(diào)整，使注塑時(shí)既能充滿模，又不會(huì)產(chǎn)生內(nèi)應(yīng)力而引起產(chǎn)品變形和開裂。下面就其在原料準(zhǔn)備、對(duì)設(shè)備和模具要求、注塑工藝和產(chǎn)品的原料處理幾方面，談?wù)剳?yīng)注意的事項(xiàng):1、原料的準(zhǔn)備與干燥由于在塑料中含有任何一點(diǎn)雜質(zhì)，都可能影響產(chǎn)品的透明度，因此和儲(chǔ)存、運(yùn)輸、加料過(guò)程中，必須注意密封，保證原料干凈。特別是原料中含有水分，加熱后會(huì)引起原料變質(zhì)，所以一定要干燥，并在注塑時(shí)，加料必須使用干燥料斗。還要注意一點(diǎn)的是干燥過(guò)程中，輸入的空氣**好應(yīng)經(jīng)過(guò)濾、除濕，以便保證不會(huì)污染原料。其干燥工藝如下表所示：2、機(jī)筒、螺桿及其附件的清潔為防止原料污染和在螺桿及附件凹陷處存有舊料或雜質(zhì)，特別是熱穩(wěn)定性差的樹脂存在，在使用前、停機(jī)后都應(yīng)用螺桿清洗劑清洗干凈各附件，使其不得粘有雜質(zhì)，當(dāng)沒(méi)有螺桿清洗劑時(shí)，可用PE、PS等樹脂清洗螺桿。當(dāng)臨時(shí)停機(jī)時(shí)，為防止原料在高溫下停留時(shí)間過(guò)長(zhǎng)，引起降解，應(yīng)將干燥機(jī)和機(jī)筒溫度降低，如PC、PMMA等機(jī)筒溫度都要降至160℃以下（料斗溫度對(duì)于PC應(yīng)降至100℃以下）。PC
