PVC-U what's the plastic tube?
PVC-U plastic pipe is light, easy to handle and load, PVC-U plastic pipe material is light, specific gravity is only iron pipe 1/5, handling, loading and unloading, construction convenience, can save construction cost. PVC-U plastic pipe corrosion resistance, good drug, PVC-U plastic pipe has excellent acid, alkali and corrosion resistance, for the chemical industry, wastewater drainage, sanitary sewage and other purposes is very suitable. The fluid resistance is small, the wall of PVC pipe is smooth, the resistance to fluid is small, the roughness coefficient is only 0.009, which is lower than other pipes. Under the same caliber condition, the flow rate is large, and the scale is not adhered to. PVC-U plastic pipe mechanical strength, PVC pipe water pressure, strength, impact resistance are good, at room temperature, PVC-U plastic pipe applies to various conditions of piping engineering.
PVC-U plastic pipe is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer, with certain additives (such as stabilizers, lubricants, fillers and so on).
Features: PVC-U plastic pipe bending performance, good chemical corrosion resistance, mechanical strength, anti-aging, temperature resistance.Carrying capacity: PVC-U plastic pipe can bear the weight of the foot, not broken.PVC-U plastic pipe application field: wire bushing, decorative casing, for liquid and oil delivery, power line protection, automotive wiring harness protection, machine tools, machinery, automation, instruments and so on.
In addition to additives, the pvc-U plastic pipe also adopts the method of blending and modifying with other resins so as to have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and so on. UPVC has high melt viscosity and poor flowability. Even if the injection pressure and melt temperature are increased, the fluidity is not changed. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the molding temperature range is very narrow. It is a difficult material to be formed.
