Upvc, also known as hard pvc, can be seen in many of our fields, but is used less in our home improvement. What is upvc ? Next, let's take a look at what material is upvc with . What is upvc It is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer plus certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to additives, methods of blending and modifying with other resins have also been used, which have significant practical value. These resins include CPVC, PE, ABS, EVA, MBS, and the like. UPVC has high melt viscosity and poor fluidity. Even if the injection pressure and melt temperature are increased, the fluidity does not change much. In addition, the molding temperature of the resin is close to the thermal decomposition temperature, and the temperature range in which molding can be performed is very narrow. A difficult-to-shape material. What needs to be known is that UPVC must be modified and granulated before it can be used. Good upvc 1, strong corrosion resistance: Compared with the general cast iron pipe, galvanized pipe, PVC pipe has a very strong corrosion resistance, can resist strong acid, strong alkali, will not rust scaling. Do not worry about the "red water" phenomenon when using it. 2, fluid resistance is small: PVC pipe wall is very smooth. The surface roughness coefficient is only 0.009, and the fluid resistance is very small, and the water pressure is not excessively reduced. 3. High mechanical strength: The UPVC pipe for water supply has good water pressure resistance, impact resistance and tensile strength, and it can withstand 110 atm for 1 hour without rupture at room temperature. 4. Hygienic and non-toxic: UPVC pipe for water supply adopts a unique green lead-free formula system instead of the traditional compound lead salt formula system, so it will not damage water quality and affect human health. 5, light texture, easy installation and construction: PVC pipe density is generally one-fifth of the cast iron, easy handling and handling. And the use of special adhesive paste or elastic seal fitting, the installation is simple and quick. 6, the temperature of the water supply pipe performance: UPVC pipe for water use temperature range, the best room temperature. The temperature is low and the brittleness increases, which is unfavorable for installation and installation; the temperature is low, the tensile strength is decreased, and the water pressure resistance performance is reduced. 7, watertight: adhesive adhesive 15 minutes, the adhesive strength can reach 12.5 / C or more, after many years of use will not be significantly reduced, and the elastic seal sleeve joints, also with PVC pipe Quite a few years of use, there is no concern of aging leaks. What kind of material about the upvc , I introduced to this, I hope to help you, more decoration information, all in this site, so stay tuned.
