As a new type of pipeline, CPVC pipe has excellent corrosion resistance. In recent years, it has been widely used in steel, metallurgy, petroleum, chemical, fertilizer, dye, pharmaceutical, electric power, environmental protection and sewage treatment industries. It is a metal anticorrosive material The ideal substitute.
Due to the increase of the chlorine content in the material, the irregularity of the CPVC molecules in the structure increases (the crystallinity decreases and the polarity of the molecular chain increases), which increases its thermal deformation temperature.
The use temperature of CPVC products can reach up to 93-100℃, which is 30-40℃ higher than that of PVC. At the same time, it improves the chemical resistance and corrosion resistance of PVC. It can resist strong acids, strong alkalis, salts, fatty acid salts, oxidants and halogens. And other chemical corrosion.
In addition, the tensile strength and bending strength of CPVC are also improved compared with PVC. Compared with other polymer materials, CPVC has excellent aging resistance, corrosion resistance and high flame retardancy. CPVC raw material has a chlorine content of 63-74%, which is higher than PVC (chlorine content 56-59%). The processing viscosity is at least twice as high, and the density of CPVC (between 1450-1650Kg/m ) is greater than that of PVC. The above data determines that CPVC is much more difficult to process than PVC.
