聚氨酯泡沫保温管的缺陷分析

Defect Analysis of Polyurethane Foam Insulation Pipes

在介绍了聚氨酯泡沫夹克保温管现有生产工艺和技术要求的基础上,对聚乙烯夹克管生产过程中出现的成型缺陷,泡沫保温管生产过程中出现的偏心缺陷和聚氨酯泡沫的性能及质量缺陷等进行了分析和探讨,通过调整原材料及工艺参数,对设备进行改进等,进一步完善了"一步法"生产线,较好地解决了保温管生产中出现的缺陷问题。

The existing production processes and techniques of polyurethane foam insulation pipes are introduced,then the molding defects produced in polyethylene jacket pipe production,the eccentric defects produced in insulation pipe production as well as the performance of polyurethane foam and quality defects are investigated.By adapting raw and processed materials and process parameters as well as improving equipment,the'one-step method'production line is consummated to solve various defect problems in the insulation pipe production.
