Characteristic 1: Rigid PVC is one of the most widely used plastic materials. PVC material is a kind of non crystalline material.
Characteristic 2: PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives in actual use.
Characteristic 3: PVC material has non flammability, high strength, weather resistance and excellent geometric stability.
Characteristic 4: PVC has strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids, such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contacting aromatic hydrocarbons and chlorinated hydrocarbons.
Characteristic 5: The melting temperature of PVC during processing is a very important process parameter. If this parameter is improper, it will lead to the problem of material decomposition.
Strong corrosion resistance: It is most suitable for anti-corrosion equipment in chemical industry. Easy processing: easy to cut, weld and bend. High strength, high stiffness and high hardness; Good electrical insulation; Good chemical stability; Self extinguishing; Low water absorption; Easy to bond and paint. Low price.
The flow characteristics of PVC are quite poor, and its process range is very narrow. In particular, PVC materials with large molecular weight are more difficult to process (such materials usually need to add lubricant to improve flow characteristics), so PVC materials with small molecular weight are usually used.The corrosion resistance and drug resistance are excellent, and the pipeline is not affected by the moisture and soil pH, so no anti-corrosion treatment is required when laying the pipeline
The valve body is light in weight, strong in corrosion resistance, compact and beautiful in appearance, easy to install, strong in corrosion resistance, wide in application, sanitary and non-toxic in material, wear-resistant, easy to disassemble, and easy to maintain. By introducing the raw material requirements, design requirements, manufacturing requirements, performance requirements, test methods, system application requirements and the relationship between operating pressure and temperature in the international standards for plastic PVC valve products and test methods, we can understand the basic quality control requirements for plastic PVC valves, such as sealing test, torque test and fatigue strength test.
