UPVC / PVC-U low pressure irrigation pipe irrigation project

First, what is known as PVC-U pipes UPVC rigid PVC, which is an amorphous thermoplastic resin, vinyl chloride monomer plus certain additives prepared by the polymerization (such as stabilizers, lubricants, fillers, etc.). In addition to using the additive, but also by blending with other resins modified approach, it has obvious practical value. These resins have CPVC, PE, ABS, EVA, MBS etc. UPVC high melt viscosity, poor mobility, even with a high injection pressure and melt temperature, liquidity will not change much. In addition, the resin molding temperature and thermal decomposition temperature is very close, can be molded very narrow range of temperatures, is a difficult molding material. Second, the characteristics of PVC-U pipe introduction 1, light weight, convenient transportation and handling: PVC pipe material is very light, convenient transportation, construction, saving labor. 2, excellent chemical resistance PVC pipe has friendship acid, alkali, corrosion resistance, for the chemical industry with very appropriate. 3, fluid resistance PVC pipe wall smooth, fluid resistance, the roughness coefficient of only 0.009, lower than other pipe, at the same flow rate, the diameter can be reduced. 4, water pressure resistance strength of the mechanical strength of PVC pipe, pressure-resistant strength, impact strength etc very good for the plumbing conditions. 5, good electrical insulation properties of PVC pipe has excellent electrical insulation for wire, cable conduits, and wire building on the pipe. 6, does not affect the water quality of PVC pipe by the dissolution test show no affect on water quality, the best current water pipe pipe 7, joining the construction of simple construction PVC pipe quickly and easily, so the low cost of construction projects
