特別是力學(xué)性能可以成倍的提升。增強改性不僅使力學(xué)性能有了飛躍，同時還賦予材料優(yōu)異的性能，其特點如下：1、比強度高：所謂比強度高是指材料的強度與相對密度之比值。通過增強有些塑料的比強度與金屬相當(dāng)。2、減震性好，過載安全性好。3、抗疲勞性好：即抗重復(fù)應(yīng)力的性能好。4、耐熱性好：通過增強，熱變形溫度可大幅提高。5、線膨脹系數(shù)小：由于纖維類材料的加入，增強材料的線膨脹系數(shù)比塑料本體低很多，因而制品成型收縮率小，可用于制造尺寸精密度要求高的產(chǎn)品。增韌改性PC在塑料中加入增韌劑以提高塑料的耐沖擊性。增韌在改性PC塑料的特點的沖擊強度大幅提高，但同時拉伸強度、彎曲強度、耐熱性有所下降。阻燃改性PC指向塑料中添加阻燃劑以提高其耐燃燒性。大多數(shù)塑料屬于易燃燒材料，用于電氣、電子設(shè)備的安全性較低，通過阻燃改性使材料的安全性有所提高。當(dāng)然阻燃改性使得材料的大多數(shù)性能有所降低。合金由兩種或兩種以上的不同塑料共混所得的體系稱為塑料合金。制備合金的目的主要是讓不同塑料的組分達到較好的互補。當(dāng)然有些性能也超過了任一單獨組分的性能。汽車外飾用耐候PC材料的開發(fā)及應(yīng)用汽車外部燈具在使用中直接受到太陽光的照射。</p><p> 其次由于透明塑料大多熔點高、流動性差，因此為保證產(chǎn)品的表面質(zhì)量，往往要在較高溫度下進行注塑，注射壓力、注射速度等工藝參數(shù)也均需作細微調(diào)整，使注塑時既能充滿模，又不會產(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:1、原料的準(zhǔn)備與干燥由于在塑料中含有任何一點雜質(zhì)，都可能影響產(chǎn)品的透明度，因此和儲存、運輸、加料過程中，必須注意密封，保證原料干凈。特別是原料中含有水分，加熱后會引起原料變質(zhì)，所以一定要干燥，并在注塑時，加料必須使用干燥料斗。還要注意一點的是干燥過程中，輸入的空氣**好應(yīng)經(jīng)過濾、除濕，以便保證不會污染原料。其干燥工藝如下表所示：2、機筒、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)沒有螺桿清洗劑時，可用PE、PS等樹脂清洗螺桿。當(dāng)臨時停機時，為防止原料在高溫下停留時間過長，引起降解，應(yīng)將干燥機和機筒溫度降低，如PC、PMMA等機筒溫度都要降至160℃以下（料斗溫度對于PC應(yīng)降至100℃以下）。PC

注塑工藝PC通稱聚碳酸酯，由于其優(yōu)良的機械性能，俗稱防彈膠。PC具有機械強度高、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。PC的工藝特性：熔融粘度對剪切率的敏感性小，而對溫度的敏感性大，無明顯熔點，熔融體粘度較高，高溫下樹脂易水解，制品易開裂。針對這些特性，我們特別要注意區(qū)別對待：要增加熔體的流動性，不是用增大注射壓力而應(yīng)采用提高注射溫度的辦法來達到;要求模具的流道、澆口短而粗，以減少流體的壓力損失，同時要較高的注射壓力;樹脂在成型加工之前需進行充分的干燥處理，使其含水量控制在此外，在加工過程中對樹脂還應(yīng)采取保溫措施，以防重新吸濕;不僅需要合理的制品設(shè)計，還應(yīng)正確掌握成型工藝，如提高模具溫度，對制品進行后處理等可以減少或消除內(nèi)應(yīng)力，視產(chǎn)品的不同狀況及時調(diào)整工藝參數(shù)。11個黃金技巧1.原料干燥PC類塑膠，即使遇到非常低之水份也會產(chǎn)生水解而斷鍵、分子量降低和物性強度降低之現(xiàn)象。因此在成型加工前，應(yīng)嚴格地控制聚碳酸酯之水份在，以避免成型品的機械強度降低或表面產(chǎn)生氣泡、銀紋等之異常外觀。PC對水極其敏感，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℃。金華老牌的PC銷售廠家</p><p
