PE燃气管材

PE燃气管材
  PE管目前中国的市政管材市场，塑料管道正在稳步发展，PE管、PP-R管、UPVC管都占有一席之地，其中PE管强劲的发展势头令人瞩目。PE管的使用领域广泛。其中给水管和燃气管是其两个大的应用市场。PE树脂，是由单体乙烯聚合而成，由于在聚合时因压力、温度等聚合反应条件不同，可得出不同密度的树脂，因而又有高密度聚乙烯、中密度聚乙烯和低密度聚乙烯之分。在加工不同类型PE管材时，根据其应用条件的不同，选用树脂牌号的同，同时对挤出机和模具的要求也有所不同。PE燃气管执行标准：GB 15558.1-2003
  PE pipe in China at present municipal pipe plastic pipe market, develop steadily, PE pipe, PP-R pipe, UPVC pipe occupy a space for one person, in which the characteristics of strong development momentum most attract people's attention. PE pipe in the wide field of use. The water supply pipe and the gas pipe is the two largest application market. PE resin, is composed of monomer ethylene polymerization, the polymerization temperature, polymerization reaction, because of the pressure of different conditions, may obtain different density of the resin, thus it has high density polyethylene, low density polyethylene and low density polyethylene branch. In the processing of different types of PE pipe, according to the application conditions of different brands of the same, the selection of resin, while the extruder and the die requirements vary.
