聚乙烯溜槽聚乙烯溜槽自从1963年在加拿大首次安装后,已很为普遍,并且已做了一些新的改进。对于材料厚度和规格的选用不当,支撑系统的设计错误及安装方面的缺陷,都已经取得了经验。但是,这种错误的使用,主要是由于现场人员在对溜槽端部处理的疏忽,以及由于矿业工程技术人员仍对于塑料的缺乏知识。下面关于材料性能及加工技术的介绍,目的是避免进一步产生错误的应用,并且使之获得最低的费用和实现其最好的性能。 Polyethylene chute Polyethylene chute has been very popular since it was first installed in Canada in 1963 and some new improvements have been made. Insufficient experience has been gained with the improper use of material thickness and specifications, design errors in support systems, and installation defects. However, this erroneous use was mainly due to the negligence of field personnel at the end of the chute and the lack of knowledge of plastic still held by mining engineers. The following description of material properties and processing techniques is intended to avoid further false application and to achieve the lowest possible cost and the best possible performance.
