This message is for homeowners in the process of home renovation. When it comes to the water and electricity phases of construction, how should you choose PP-R pipes? Are imported PP-R pipes always better than domestically produced ones? Many companies in this province also produce PP-R pipes; what is the quality of their products? Answers to these questions can be found at the press conference on the comparative quality of Zhejiang Province's PP-R pipe materials, to be held on the morning of November 8th, hosted by the Zhejiang Chemical Building Materials Association. This comparative quality activity was jointly conducted by Zhejiang Fangyuan Testing Group Co., Ltd. and the Zhejiang Chemical Building Materials Association. A total of 44 companies in the province were randomly checked during this event.

What tools are needed to clean PPR pipes?
When cleaning PPR pipes, what tools are needed? Which tool is essential? 1. When cleaning PPR pipes with a cleaning machine, a floor heating cleaning machine is used for thorough cleaning. Floor heating cleaning machines are held by professional pipe cleaning personnel and require many interfaces, making it easy for non-professionals to make mistakes. Cleaning PPR pipes is a professional job that is best left to professionals for better results. 2. To clean the exterior of PPR pipes with a cloth, use a soft cloth. First, wipe the PPR pipe body with a clean, dry cloth. If it is not clean enough, you can wipe it with a damp cloth, which usually cleans it. If

Causes and preventive measures for the low-temperature brittleness of PPR pipes in winter
The reasons and preventive measures for the low-temperature brittleness of PPR pipes in winter are well known. PPR pipes are susceptible to low-temperature brittleness and may crack under external impact or heavy pressure. So what causes this phenomenon, and how can it be prevented? 1. Why do PPR pipes exhibit low-temperature brittleness? Answer: PP-R is a random copolymer of polypropylene, also known as Type III polypropylene. It is obtained by the random copolymerization of propylene monomers and a small amount of ethylene monomers under heating, pressure, and catalysis. Ethylene monomers are randomly distributed in the propylene chains, with the ethylene monomer content generally controlled between 3-5%. The ethylene content and the ratio of ethylene to propylene
