空心绝缘管注射后缩短原因分析

The Reason Study of Insulating Hollow Tube Shortening after Injection

复合绝缘管在注射后长度出现缩短现象。其主要原因包括以下三个方面:固化程度不完全、绝缘管内应力未完全释放、环境湿度大导致固化剂甲基四氢苯酐水解;且外,本文对绝缘管注射后缩短给出了有效的解决方案。

The reasons for the contraction of the tube after injection are as follows: incomplete curing degree, not-fully-released internal stress of the tube, and MTHPA hydrolysis because of the environmental humidity. Furthermore, this paper gives effective solutions for the above problem.
