Polytetrafluoroethylene pipe manufacturers analyze the application prospect of CPVC. PVC is modified by chlorination to obtain high-function CPVC. After modification, the use temperature, chemical stability, aging resistance, flame retardant and smoke suppression of PVC have been greatly improved. Its comprehensive function exceeds the general ABS. Especially suitable for some of the temperature and fire have special needs of the occasion, its development prospects are very broad.
At present, the use of CPVC in China is still in the development stage, but in the following areas, CPVC rod has shown obvious advantages:
The thermal conductivity of CPVC pipes for crude oil gathering and transportation in 1. oilfield is only 1/200 of that of steel pipes. The thermal insulation function of crude oil in the gathering and transportation process is excellent, which can save a lot of energy. Other CPVC pipes have small friction coefficient, and their flow rate is at least 1.25 times that of steel pipes under the same conditions, and they are light in weight and convenient to install. Its excellent chemical stability and temperature resistance, coupled with the inherent wear resistance and non-scaling advantages of plastic pipes, make it show obvious advantages in crude oil gathering and transportation, and the service life is at least 8 times that of steel pipes. After glass fiber (GF) winding and cladding enhancement, the use pressure can reach 20 ~ 60MPa, which can basically satisfy the crude oil gathering and transportation under low, medium and high pressure conditions.
2. chemical with temperature resistance, corrosion resistance pipe, plate and sheet CPVC good temperature resistance and chemical corrosion resistance, making it able to withstand strong acid, alkali and salt water corrosion, and the maximum temperature of up to 95~98 ℃, it can also be satisfied with the mechanical strength of chemical equipment in demand. Expected service life of up to 50 years. In addition, the oxygen index of CPVC data is greater than or equal to 50%, and it has excellent flame retardancy and smoke suppression. It is the ambition (ambition store) data of chemical equipment that needs to meet the fire protection requirements. If the processing technology can be properly installed, the CPVC pipe can have a reliable sealing function, and the phenomenon of running, running, dripping and leaking in chemical production can be solved. In short, CPVC functions more than ABS and UPVC, and will be their replacement commodities.
3. water supply and drainage pipes for hot water and warm water should be properly processed and formulated. CPVC can be produced into large diameter pipes, and can be connected by the most reliable and convenient flared socket flexible sealing ring at present, which cannot be realized by PP-R, PE-X and aluminum-plastic composite pipes. Therefore, CPVC has a large use space in occasions where hot water and warm water needs to be transported in industries, mines, construction, electric hot spring baths and other occupations.
4. information for occasions with strict fire protection requirements Because of CPVC's excellent flame retardancy and smoke elimination, this 1 of information has become the first choice for plastic products with strict fire protection requirements. It includes packaging, construction and decoration of electronic and electrical products, and transportation facilities (including aviation). Its prospects are very attractive.
5. the development of modern cities with high-voltage and ultra-high-voltage power transmission cable guards, buried power transmission cables are required, which requires cable guards to have excellent heat resistance, insulation, easy laying of cables and flame retardancy. CPVC pipe precisely has these functions. At present, it has been widely used in these 1 areas by some advanced countries, and China has also begun to try this aspect, and has been selected by the power grid transformation of some large and medium-sized cities. CPVC, a new 1 of plastic materials, has recently been carried out rapidly and has been paid more and more attention in our country. As a new category of plastic occupation, its prospect is immeasurable.
