1, early stop warming precautions
The heating pressure will change on the day when the heat is stopped. It is best for residents to keep an eye on whether there is any leakage point. Please (especially the user of the radiator packaging) check if the heating facilities in the home are leaking, seepage, and serious corrosion of the facilities (especially Is the kitchen heating take over, indoor pipe through the wall and the bathroom radiator material).
2ã€Whether the water in the heating system needs to be released after it is stopped
Some users believe that after warming, the water inside the heater should be released to prevent the inner wall of the radiator from rusting. In fact, there is water in the heating system that does not rust. This is because the heating water is filled with a large amount of chemicals that can prevent corrosion of the radiators and pipes, and at the same time the full water condition effectively blocks the contact between the air and the inner wall. , Reduced the chance of oxidation corrosion, can extend the service life of radiators and pipes.
3, how to maintain the radiator in the non-heating period
First, it must be filled with water to prevent the radiator from being oxidized and corroded. Second, pay attention to the surface of the radiator. Clean it with a clean rag. Use stubborn dirt to clean it. Use strong soapy water to clean it. Must not use corrosive cleaners. Also, do not scratch with sharp objects to prevent damage to the radiator. For the heating pipe, the filter screen of the filter also needs to be cleaned in time to prevent the contaminated dirt from clogging the pipe during the outage, and it is difficult to clean it when it is used again.
Although it is now in the spring of March, but the spring is still cold, so once you stop warming, the residents will feel uncomfortable. In order to prevent colds, residents should properly add clothes at home, especially in the cold at night, they should be covered with quilts to keep warm.

In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
the Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.
