PPR管为什么会有低温脆性的特点？它是由单体和少量乙烯单体在加热、加压和催化剂作用下无规共聚得到的。乙烯单体随机地分布到长链中，PVC水管电话，其中乙烯单体一般控制在3-5%之间。乙烯含量和乙烯与的聚合方式决定了其具有低温脆性的特点。
Why does PPR pipe h***e the characteristics of low temperature brittleness? It is obtained by random copolymerization of monomer and a ***all amount of ethylene monomer under heating，PVC水管品牌， pressure and catalyst. Ethylene monomer is randomly distributed in long chain， and ethylene monomer is generally controlled between 3-5%. The content of ethylene and the polymerization of ethylene determine its low temperature brittleness.
Uk Gafloon Pipe Group Ltd 提醒您水电安装预埋管线注意事项给排水部分
·外墙雨水管、空调冷凝水管预留洞时要考虑外墙保温的厚度，避免二次修洞。
·室内排污管的标高比设计标高可以高出5-10cm，PVC水管，这样可避免室外排水管网的坡度太小 。
Uk Gafloon Pipe Group Ltd reminds you for water and electricity installation and water supply and drainage
·The thickness of external wall insulation chould be regarded when reserving holes for external wall rainwater pipe and air conditioning condensate pipe to ***oid secondary hole repair.
·The elevation of indoor sewage pipe can be 5-10cm higher than the design elevation，PVC水管咨询， as to ***oid too ***all slope of outdoor drainage pipe network.
根据耐腐蚀性能来参考?
具体来说，PPR管材耐腐蚀与防结垢性能则施工项目管道的基本需求，优良的PPR管材的耐化学腐蚀性能更好，其能够抵抗水中的化学元素的腐蚀，与此同时，其表面则可避免水垢的形成，以此可以促使输送的水更加洁净与卫生。
According to the corrosion resistance
Specifically，Corrosion resistance and anti scaling performance of PPR pipe are the basic requirements of building project pipeline. Excellent PPR pipe has better chemical corrosion resistance， which can resist the corrosion of chemical elements in water. At the same time， its surface can ***oid the formation of scale， which can promote the tran***ission of water more clean and sanitary.
