注塑工藝PC通稱聚碳酸酯，由于其優(yōu)良的機(jī)械性能，俗稱防彈膠。PC具有機(jī)械強(qiáng)度高、使用溫度范圍廣、電絕緣性能好（但防電弧性能不變）、尺寸穩(wěn)定性好、透明等特點(diǎn)。PC的工藝特性：熔融粘度對(duì)剪切率的敏感性小，而對(duì)溫度的敏感性大，無(wú)明顯熔點(diǎn)，熔融體粘度較高，高溫下樹脂易水解，制品易開(kāi)裂。針對(duì)這些特性，我們特別要注意區(qū)別對(duì)待：要增加熔體的流動(dòng)性，不是用增大注射壓力而應(yīng)采用提高注射溫度的辦法來(lái)達(dá)到;要求模具的流道、澆口短而粗，以減少流體的壓力損失，同時(shí)要較高的注射壓力;樹脂在成型加工之前需進(jìn)行充分的干燥處理，使其含水量控制在此外，在加工過(guò)程中對(duì)樹脂還應(yīng)采取保溫措施，以防重新吸濕;不*需要合理的制品設(shè)計(jì)，還應(yīng)正確掌握成型工藝，如提高模具溫度，對(duì)制品進(jìn)行后處理等可以減少或消除內(nèi)應(yīng)力，視產(chǎn)品的不同狀況及時(shí)調(diào)整工藝參數(shù)。11個(gè)黃金技巧1.原料干燥PC類塑膠，即使遇到非常低之水份也會(huì)產(chǎn)生水解而斷鍵、分子量降低和物性強(qiáng)度降低之現(xiàn)象。因此在成型加工前，應(yīng)嚴(yán)格地控制聚碳酸酯之水份在，以避免成型品的機(jī)械強(qiáng)度降低或表面產(chǎn)生氣泡、銀紋等之異常外觀，無(wú)錫優(yōu)惠的PC科思創(chuàng)。PC對(duì)水極其敏感，所以注塑前必須充分干燥，使其含水量降低到，PC一般干燥條件：100~120℃。韓國(guó)樂(lè)天，抗紫外線，無(wú)錫優(yōu)惠的PC科思創(chuàng)，透明，高剛性，無(wú)錫優(yōu)惠的PC科思創(chuàng)，高抗沖，**度。無(wú)錫優(yōu)惠的PC科思創(chuàng)</p><div

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(kāi)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）。麗水哪家PC日本三菱PC
