UPVC, also known as hard PVC or PVCU, is composed of an amorphous thermoplastic resin made by the polymerization of vinyl chloride monomer and certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to using additives, the method of blending with other resins is also used to make it have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and so on. UPVC has high melt viscosity and poor fluidity. Even if the injection pressure and melt temperature are increased, the fluidity will not change much. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range that can be molded is very narrow, making it a difficult-to-mold material.
1. Light weight, convenient to handle and unload:
The material of PVC pipe is very light, it is convenient to handle and construct, and it can save labor.
2. Excellent chemical resistance
PVC pipe has excellent acid resistance, alkali resistance, and corrosion resistance, which is very suitable for use in the chemical industry.
3. Small fluid resistance
The wall surface of the PVC pipe is smooth, and the resistance to the fluid is small. Its roughness coefficient is only 0.009, which is lower than other pipe materials. Under the same flow rate, the pipe diameter can be reduced.
4. High mechanical strength
The water pressure resistance, external pressure resistance and impact resistance of PVC pipes are all very good, and it is suitable for piping projects under various conditions.
5. Good electrical insulation
PVC pipe has excellent electrical insulation and is suitable for conduits of wires and cables, and wire piping in buildings.
6. Does not affect water quality
The dissolution test proves that the PVC pipe does not affect the water quality, and it is the best pipe material for tap water piping at present.
7. Easy construction
The joint construction between PVC pipes is quick and easy, so the construction engineering cost is low
