我們?nèi)粘Ｉ钪须S處可見到PC塑膠原料制品的身影，給我們的生活帶來了很多便利。要想生產(chǎn)出高質(zhì)量的PC塑膠原料制品，都會很重視PC塑膠原料造粒這一步驟的，現(xiàn)介紹下PC塑膠原料造粒的工藝技巧。一、看顆粒表面光澤度和密實(shí)度塑化不良，顆粒疏松：表面無光澤是因?yàn)樵炝囟群屠鋮s水溫度控制不當(dāng)，這就要求調(diào)解PC塑膠原料造粒工藝過程中的造粒溫度。二、學(xué)會聽聲音進(jìn)料速度的快慢和溫度高低的變化，機(jī)器所發(fā)出的聲響都有很大的不同。這需要在實(shí)踐中不斷摸索，要盡力讓機(jī)器保持在運(yùn)轉(zhuǎn)比較好時的聲音狀態(tài)中，這樣可以保證塑料造粒工藝更加完美。三、學(xué)會看料看從機(jī)頭出來的PC塑膠原料非常重要，因?yàn)檫@是查找原因的關(guān)鍵。有生料，則溫度過低，須加溫;有焦料，則溫度過高，須降溫等等。要想提高PC塑膠原料造粒工藝的技巧，就要在PC塑膠原料造粒過程中一定得多聽多看多摸索，才能發(fā)現(xiàn)問題并及時糾正。</p><p> 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(jìn)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(qiáng)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(xiàng)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。韓國樂天，PC-1100U,耐候，抗紫外線，高剛性，高抗沖，**度。</p><div
