1. Poor stain resistance, must be waxed and maintained regularly. 2. Contains a certain amount of stone powder, no PVC wear-resistant layer on the surface 3. Fear of cigarette butt burns 4. The texture is hard, and the fo
1. Structural differences: tpe: hydrocarbon polymer; pvc: hydrocarbon polymer containing chlorinated hydrocarbons. 2. The difference in specific gravity: tpe: the specific gravity is 0.84-1.4, which is lighter; pvc: the specifi
1. Pipes: PVC is mainly used for the production of pipes, transporting hot water and corrosive media. It can maintain sufficient strength when the temperature does not exceed 100 ℃, and can be used for a long time under high inter
Polyvinyl chloride, English abbreviation PVC (Polyvinyl chloride), is vinyl chloride monomer (VCM for short) in peroxide, azo compound and other initiators; or under the action of light and heat according to the mechanism of free
The tube extruded from the die of the machine head is cooled to make it hard and set. There are generally two ways of setting the outer diameter and inner diameter by using the sizing sleeve. Among them, the outer diameter shaping
The screw of the extruder is divided into 3 sections: feeding section (feeding section), melting section (compression section), metering section (homogenization section), these three sections correspond to the material to form 3 f
When mixing at high speed, the additive penetrates into the voids of the PVC resin, so that the additive is evenly dispersed in the resin. Considering that the temperature above 100°C is conducive to the evaporation of water v
Polyvinyl chloride is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization.
Polyvinyl chloride, referred to as PVC, is a polymer made of vinyl chloride as a monomer through free radical polymerization. Because the electron-withdrawing substituent of the chlorine atom on vinyl chloride is p-π conjugated
paracords is not only one piece of versatile survival gear, but also a fun way to pass the time. Anything that paracords can do, ordinary rope can do too. However, the versatility of paracords is something it doesn&
