The list of water and electricity materials given by the master uses Cai Zhong brand plastic water pipes. There are two problems. 1 Can plastic water pipes be used for home decoration? 2 What is the quality of pipelines in Cai Zhong? PPR tube is nontoxic, but it can be used for home decoration. I use PPR tube for home decoration. Now many pipe manufacturers have PPR pipes for home decoration. My home is decorated with Cai Zhong PPR pipes. At that time, my friend recommended to me that the steel pipes of Cai Zhong PPR were of very good quality, and I personally inspected them. Cai Zhong has no negative news, and the test tube has no smell. Don't worry.

The following are the answers of other netizens:

Zhongcaiguan is a famous brand in China and a well-known trademark in China. It has a good reputation in the industry and a good reputation. No negative news. Zhongcaiguan relies on large enterprises, especially group enterprises. At present, it has many subsidiaries and production bases all over the country. PPR tube: The official name of PPR is random polypropylene, which is a random polymer of propylene and other olefin monomers, and there are no other functional groups in the olefin monomers.

As a new type of water pipe, Cai Zhong PPR pipe has the following characteristics:

1. It is sanitary and nontoxic, and can be directly used in the pipeline system of pure water and drinking water.

2. Corrosion resistance, difficult scaling, eliminating the secondary pollution caused by corrosion and scaling of galvanized steel pipes.

3. Heat resistance, long-term delivery of hot water below 70℃ and instantaneous high temperature of 95℃.

4. Good thermal insulation performance. The thermal conductivity at 20℃ is only about 1/200 of steel pipe and11400 of red copper pipe.

5. Light weight and high strength. The density of PPR is 0.89 ~ 0.9 1g/cm3, which is only 1/9 for steel pipe and1/0 for copper pipe.

6. The fluid resistance in the pipeline is small, the inner wall of the pipeline is smooth, and it is not easy to scale. The fluid resistance is much lower than that of the metal pipeline.

7. Hot melt socket connection is adopted, which is simple and reliable to install and has long service life.
