style="text-indent:25px">pp塑膠原料等規(guī)度對(duì)于紡制丙綸纖維時(shí)的成絲性能和纖維的質(zhì)量有明顯的影響。等規(guī)度高，結(jié)晶性好，對(duì)成絲性能和絲的質(zhì)量有益。pp塑膠原料等規(guī)度除了影響制品性能外，還影響樹(shù)脂的加工性能。等規(guī)度低，產(chǎn)品發(fā)粘，流動(dòng)性差，包裝儲(chǔ)存時(shí)易板結(jié)成塊、團(tuán)，加工時(shí)加料困難，甚至無(wú)法加工。pp塑膠原料等規(guī)度過(guò)低還會(huì)影響pp塑膠原料的正常生產(chǎn)和操作。一般等規(guī)度低于90%時(shí)，產(chǎn)品就會(huì)出現(xiàn)發(fā)粘現(xiàn)象。當(dāng)?shù)纫?guī)度低于85%時(shí)，產(chǎn)品發(fā)粘厲害，會(huì)在環(huán)管反應(yīng)器內(nèi)壁、出料口、閃蒸罐及管線內(nèi)等處造成嚴(yán)重的粘壁現(xiàn)象，影響操作和正常生產(chǎn)。pp塑膠原料的沖擊強(qiáng)度隨著乙烯含量的增加而增大。浙江透明pp塑膠原料廠</p><p

style="text-indent:25px">pp塑膠原料要與顏色配合,因此塑膠原材料可分為:抽粒料,色粉料,色種料,還有近期出現(xiàn)的加液體在塑膠原材料中著色.抽粒原料是已經(jīng)把顏料混合進(jìn)原料中,每一粒塑料料均已著色,所以形成產(chǎn)品顏色穩(wěn)定均勻.色粉料及色種料是把色種或色粉混合原料使用,成本低,而且不用儲(chǔ)存大量的有色原料.但是顏色不穩(wěn)定,較難在生產(chǎn)中控制統(tǒng)一性。pp塑膠原料擠出的基本機(jī)理很簡(jiǎn)單—一個(gè)螺桿在筒體中轉(zhuǎn)動(dòng)并把塑料向前推動(dòng)。螺桿實(shí)際上是一個(gè)斜面或者斜坡，纏繞在中心層上。其目的是增加壓力以便克服較大的阻力。就一臺(tái)擠出機(jī)而言，有3種阻力需要克服：固體顆粒（進(jìn)料）對(duì)筒壁的摩擦力和螺桿轉(zhuǎn)動(dòng)前幾圈時(shí)（進(jìn)料區(qū)）它們之間的相互摩擦力；熔體在筒壁上的附著力；熔體被向前推動(dòng)時(shí)其內(nèi)部的物流阻力。吹塑管材級(jí)RB240ppp塑膠原料直銷價(jià)格</p></p><br
