6、制品后處理：對于形狀復(fù)雜、帶有金屬嵌件、使用溫度極低或很高的制品有必要進行后處理——消除或減少內(nèi)應(yīng)力。方法：制品置于烘干箱后開始升溫，由室溫升至100—105時保溫10—20min，繼續(xù)升溫至120—125時保溫30—40min，然后緩慢冷卻至60以下取出。粘接問題根據(jù)不同需要，可以選擇以下粘合劑：：單組分常溫固化軟彈性防震粘合劑，耐高低溫，不同粘度粘接速度幾秒至幾個小時固化完畢，固化后膠層透明無痕跡；，可以數(shù)秒鐘或數(shù)十秒鐘快速粘合PC塑料，但膠層硬脆，不耐60度以上熱水浸泡；，雙組分膠，膠層柔軟，適合PC塑料大面積粘接或復(fù)合。但耐高溫性能較差；：雙組分膠，耐高溫；，固化后是彈性體具有***的防水，防震粘合劑，耐高低溫，1-2mm厚度的話，15分鐘左右初固，5-6小時基本固化，有一定的強度。完全固化的話需要至少24小時。單組份，不需要混合，擠出后涂抹靜置即可，無需加溫[2]注意事項成型過程問題產(chǎn)生原因及解決辦法1、銀絲a、原材料受潮————干燥原料b、樹脂過熱分解————減低成型溫度c、螺桿壓縮比小。</p><p> ABS則能改進可成型性，表觀質(zhì)量，降低密度。聚碳酸酯的性能以及成型參數(shù)見表：（*供參考）密度一、原料的干燥1、原料烘干：普通烘干箱溫度110—130，時間2—4小時，機頂料斗烘干箱溫度100—120，要求水分含量低于。2、判斷水含量是否合格：看空***的料條情況，物料通過塑化后由噴嘴流出來的料條應(yīng)是均勻無色、無銀絲和無氣泡的細條；否則則是烘干不徹底。二、***工藝1、注塑機調(diào)整成型參數(shù)（視原料分子量高低調(diào)整）：料筒溫度：前部250—310，中部240—280，后部230—250。噴嘴溫度：比后部低10。模具溫度：70—120。***壓力：70—140MPa。螺桿轉(zhuǎn)速：30—120r/min。成型周期：***1—25s，冷卻5—40s。三、注意事項1、***溫度視原料的分子量、制品的形狀和尺寸、注塑機的類型而相應(yīng)調(diào)整。2、***速度**好采取多級***，采用慢-快-慢的方法。3、***壓力視制品的形狀和尺寸而定，柱塞式注塑機一般為100—160MPa，螺桿式注塑機為70—140MPa。4、成型周期視制品壁厚和***量而定，一般情況下充模時間較短，保壓時間較長，冷卻時間以脫模時不引起制品變形為原則。5、模具溫度視制品的形狀、厚薄而定，適當(dāng)提高模具溫度有利于脫模，提高產(chǎn)品質(zhì)量。沙伯基礎(chǔ)（原GE）**度，家用電器，透明，耐候，薄膜級，電線電纜，尺寸穩(wěn)定性良好，抗沖擊性，照明工具。</p><div

pc材料就是聚碳酸酯材料，Polycarbonate，是一種無色透明的無定性熱塑性材料。機械強度非常高，聚碳酸酯無色透明，耐熱，抗沖擊，阻燃，不需要添加劑就具有UL94V-0級阻燃性能。PVC材料就是聚氯乙烯材料，是目前產(chǎn)量居第二位的通用塑料，也是用途廣的塑料，PVC本身也是無色透明的硬質(zhì)材料，但比PC脆的多，透明度也不如PC，其它的機械性能也與PC相差很遠。但PVC可以加入很多增塑劑，加入后就可以做成軟質(zhì)PVC。所謂硬PVC就是100公斤PVC樹脂粉里增塑劑添加量少于5公斤的聚氯乙烯PVC塑料，象建筑用下水管、落水管、塑鋼窗、之類的都是屬于硬PVC。增塑劑添加量大于5公斤叫半硬PVC，大于25公斤叫軟PVC，象普通電線外皮、一次性輸液管、一些充氣玩具、軟門簾、超市賣的那種叫軟玻璃的透明塑料桌墊等都是軟PVC的。PVC還可以任意著色，做成各種透明不透明的彩色制品，所以PVC是目前用途范圍廣的塑料，價格只有PC的1/2到1/4左右。3.工業(yè)合成PC是雙酚義型、結(jié)晶度，而無鹵環(huán)保磷系阻燃劑會明顯降低PC的熱變形溫度和沖擊強度，因此比較適宜的是有機硅系阻劑是以聚氯乙烯樹脂為主要原料，加入適量的抗老化劑、改性劑等，被運用于生產(chǎn)和生活中。譬如PVC水管、PVC塑料門窗。韓國樂天，PC-1100U,耐候，抗紫外線，高剛性，高抗沖，**度。嘉興口碑好的PC行情</p><p
