Description

Technical Field

[0001] The utility model relates to the field of processing clamping devices, in particular to a clamping device for processing hard polyvinyl chloride pipes. Background Art

[0002] Rigid polyvinyl chloride, UPVC, also known as hard PVC, is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and certain additives (such as stabilizers, lubricants, fillers, etc.). But strictly speaking, UPVC is hard PVC, and hard PVC is not UPVC. To discuss UPVC rigorously and scientifically, UPVC should not contain or use plasticizers, while hard PVC contains plasticizers. Polyvinyl chloride is polymerized from vinyl chloride monomer (VCM). Because 57% of the mass of its molecules is chlorine. Therefore, compared with other plastics, it consumes less oil in the same mass. However, because this plastic has a large relative density and consumes other energy in the process of generating chlorine, it loses its advantages in many application fields. The most commonly used PVC production process is the suspension polymerization production process. Pure water, liquefied VCM monomer, and dispersant are added to the reactor, and then initiators and other additives are added. After heating to a certain temperature, the VCM monomer undergoes free radical polymerization to generate PVC particles. Continuous stirring makes the particle size uniform and makes the generated particles suspended in the water. Rigid polyvinyl chloride is mainly used in rigid PVC pipes and fittings, profiles, usually with a diameter of 40-100mm, smooth inner wall with low resistance, no scaling, non-toxic, non-polluting, corrosion-resistant, and an operating temperature of no more than 40 degrees, so it is a cold water pipe with good anti-aging performance and flame retardancy. It can be installed with a rubber ring flexibly connected and used for water supply (non-drinking water), drainage pipes, and rainwater pipes.

[0003] According to the patent of a clamping device for processing rigid polyvinyl chloride pipes (publication number: CN217072588U), the utility model belongs to the technical field of clamping devices, especially a clamping device for processing rigid polyvinyl chloride pipes.

The utility model is easy to assemble, can adapt to pipes of different sizes, and has a wide range of applications.
