(一)工作原理
1,相对回转---两个相邻的辊筒在有速比或等速情况下相对回转;
2,胶料在摩擦力作用下被拉入辊隙中,
3,由于辊隙截面的逐渐减少,三辊压延机订购,使胶料受到强烈的挤压与剪切,完成延展成型(压片);或把胶料挤压在钢丝帘布上(双面贴胶);胶胚表面压花(压型);多层胶片的贴合等.由于辊隙截面的逐渐减少,使胶料受到强烈的挤压与剪切,完成延展成型(压片);或把胶料挤压在钢丝帘布上(双面贴胶);胶胚表面压花(压型);多层胶片的贴合等.
化学工业上什么是辊速比相关论述
辊速比
英文名称: roll speed ratio;friction ratio CAS号: 分 子 式:
相关内容概述: 指相邻两个辊筒线速度之比,是压延机操作中使用的术语。压延机在加工塑料薄膜或片材的时候,利用相邻压延辊线速度的不同和辊距的变化等,使塑料在压延1时能更好地进行剪切、塑化,使料片顺利地从一个压辊转移到另一压辊上,从而获得规定厚度和满意质量的成品,压延机就是根据辊筒配置情况,分别称L型三辊压延机、Z型四辊压延机等。开炼机的辊速比一般为1:1.2~1:1.3。压延机擦胶时的三辊筒的速比一般为1:1.3~1.5:1(上辊:中辊:下辊)。辊筒速比的大小表示两辊间的剪切力与摩擦力的大小。密炼机的辊筒转速较快,故速比较低,一般为1:1.14~1:1.19
