【摘要】 聚氯乙烯托辊在非金属托辊中具有一定的代表性,其轴承座与辊筒的连接是生产中较难解决的工艺问题。本文在研究非金属托辊结构的工艺特点及塑料焊接性能的基础上,对新型聚氯乙烯托辊的连接采取热气焊接的措施,并对具体工艺做了说明。更多还原

【Abstract】 The PVC idlers have an important representativeness in the turn-metallic PVC rollers. The technological problems of the connection between the bearing chock and idler roll is more difficult to solve in production. On the basis of the research on the technological features of the non-metallic roller structure and the plastic welding performance, a measure is taken on the connection of a new-type PVC rollers by hot air welding. And the specific process is described.更多还原
