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,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 have the characteristics of low temperature brittleness? It is obtained by random copolymerization of monomer and a small amount of ethylene monomer under heating, pressure and catalyst. Ethylene monomer is randomly distributed in long chain,十堰PVC管业, and ethylene monomer is generally controlled between 3-5%. The content of ethylene and the polymerization of ethylene determine its low temperature brittleness.由于那些普通的(未添加其他的材质的)PPR管的刚性并不是很好的,明装ppr水管道会发生变形的情况,PVC管业咨询,造成不美观的现象,而且还不具有阻氧的能力,PVC管业电话,一些生产厂家在PPR水管的外面加了一层铝皮(称之为稳态管)。ppr水管在熔焊前,需要用的剥皮工具将管端插入到管件的那一段铝皮剥去,其余的连接操作步骤和注意事项与普通PPR管一样。
现在,PVC管业加工,一些小的宾馆或一些建筑物的部分商业、办公区域也需要用到采暖和生活热水,他们的热负荷或生活热水用量要比家庭大许多(即并联安装若干台燃气壁挂炉);因此热水管的管径比较大,在与集分水器、隔离罐、控制附件等连接时需要用到法兰连接。
Now, some small hotels or some commercial and office areas of some buildings also need heating and domestic hot water, and their heat load or domestic hot water cost is much larger than that of families (that is, several gas-fired wall mounted boilers are installed in parallel); Therefore, the diameter of the hot water pipe is relatively large, and flange connection is needed when connecting with the water distributor, isolation tank, control accessories, etc.
