時(shí)間至少4小時(shí)以上;2.注射溫度注射溫度必須綜合制品的形狀、尺寸、模具結(jié)構(gòu)、制品性能、要求等各方面的情況加以考慮后才能作出。一般在成型中選用溫度在270~320℃之間，過(guò)高的料溫如超過(guò)340℃時(shí)，PC將會(huì)出現(xiàn)分解，制品顏色變深，表面出現(xiàn)銀絲、暗條、黑點(diǎn)、氣泡等缺陷，同時(shí)物理機(jī)械性能也下降。PC溫度很敏感，熔體粘度隨溫度升高而明顯下降，料筒溫度250~320℃.(好不要超過(guò)350℃)，適當(dāng)提高料筒溫度對(duì)PC塑化有好處。必要時(shí)內(nèi)應(yīng)力退火，烘爐溫度125~135℃，時(shí)間2小時(shí)，自然冷卻到常溫。3.注射壓力對(duì)PC制品的物理機(jī)械性能，內(nèi)應(yīng)力、成型收縮率等有一定的影響對(duì)制品的外觀及脫模性有較大的影響，過(guò)低或過(guò)高的注射壓力都會(huì)使制品出現(xiàn)某些缺陷。一般注射壓力控制在80-120MPa之間，對(duì)薄壁，長(zhǎng)流程，形狀復(fù)雜，澆口較小的制品，為克服熔體流動(dòng)的阻力，以便及時(shí)充滿模腔，才選用較高的注射壓力(120-145MPa)，從而獲得完整而表面光滑的制品。流動(dòng)性差，需用高壓注射，但需顧及膠件殘留大的內(nèi)應(yīng)力(可能導(dǎo)致開(kāi)裂)注射速度：壁厚取中速，壁薄取高速。4.保壓壓力及保壓時(shí)間保壓壓力的大小及保壓時(shí)間的長(zhǎng)短對(duì)PC制品的內(nèi)應(yīng)力有較大的影響，保壓壓力過(guò)小。舟山專業(yè)的PC是什么沙伯基礎(chǔ)（原GE）**度，家用電器，透明，耐候，薄膜級(jí)，電線電纜，尺寸穩(wěn)定性良好，抗沖擊性，照明工具。</p><div
