PVC管材的生产工艺与设备操作介绍

PVC管材的生产工艺与设备操作介绍 PVC塑料是一种多组分材料,根据不同的用途可加入不同添加剂,因组分不同,PVC制品呈现不同的物理力学性能,针对不同场合应用。而PVC塑料管在塑料管中所占的比例比较大。 PVC管材分为硬软两种,RPVC管是将PVC树脂与稳定剂、润滑剂等助剂混合,经造粒后挤出机成型制得,也可采用粉料一次挤出成型。RPVC管耐化学腐蚀性与绝缘性好,主要输送各种流体,以及用作电线套管等。RPVC管易切割、焊接、粘接、加热可弯曲,因此安装使用非常方便。SPVC管材具有优良的化学稳定性,卓越的电绝缘性和良好的柔软性和着色性,此种管常用来代替橡胶管,用以输送液体及腐蚀性介质,也可用作电缆套管及电线绝缘管等。 一、PVC硬管 1、原料配方及选择 硬管生产中树脂应选用聚合度较低的SG-5型树脂,聚合度愈高,其物理力学性能及耐热性愈好,但树脂流动性差,给 ...
