早在1912年德国就研究成功了用盐酸与乙炔在催化剂作用下生产PVC树酯的方法。但是直到1935年,PVC树脂的质量问题以及生产管材过程中所用的热稳定剂得到解决之后,才生产出PVC管。1914年德国制定了第一个关于uPVC管的工业标准。第二次世界大战以后,塑料管的制造商和用户共同进行了大量的研究工作,并将uPVC管用作饮用水管道。但当时还有许多问题没有解决,例如冷脆性、配套管件的生产和连接、安装技术等问题。直到五十年代这些问题得到解决之后,uPVC管才被广泛地使用。同时,有关uPVC管在使用初期管
As early as 1912, Germany successfully developed a method for producing PVC resin with hydrochloric acid and acetylene under the action of a catalyst. However, PVC pipes were not produced until 1935 when the quality of the PVC resin and the heat stabilizers used in the production of the pipes were solved. In 1914 Germany established the first industrial standard for uPVC pipes. After the Second World War, plastic pipe manufacturers and users jointly conducted a lot of research work and used uPVC pipes as drinking water pipes. However, there were still many problems that were not solved at the time, such as cold brittleness, production and connection of fittings, and installation technology. Until these problems were solved in the fifties, uPVC pipes were widely used. At the same time, related to the use of uPVC tubes in the early stages of use
