PVC, a thermoplastic resin that is polymerized by chloroethylene under the action of initiator.
It's the homopolymer of vinyl chloride.
Vinyl chloride and vinyl chloride copolymer are collectively referred to as chloroethylene resin.
PVC is the white powder of amorphous structure, the brandization degree is small.
The PVC molecular weight of industrial production is generally in the range of 50, 000 to 120,000, with greater dispersion, and the molecular weight increases with the decrease of polymerization temperature.
No fixed melting point, 80 ~ 85 ℃ began to soften, 130 ℃ is a viscoelastic state, 160 ~ 180 ℃ began to change for the viscous flow;
Good mechanical properties, tensile strength of 60MPa, impact strength 5 ~ 10kJ/m squared;
Excellent dielectric properties.
But poor stability to heat and light, in more than 100 ℃ or the sun for a long time, will decompose and produce hydrogen chloride, and further automatic catalytic decomposition, cause discoloration, physical and mechanical properties also fell rapidly, must be added in the practical application of stabilizers in order to improve the stability of heat and light.
PVC is very hard, also have a poor solubility, can only dissolve in cyclohexanone, dichloroethane and tetrahydrofuran few solvents, such as the organic and inorganic acid, alkali, salt are stable, chemical stability and decreased with the temperature increasing of use.
PVC is dissolved in acetone - disulphide or acetone - benzene mixed solvents, used in dry spinning or wet spinning to form fibers, called polychloroprene.
It has the hard burning, acid and alkali resistance, anti-microbial, wear-resisting and good heat preservation and elasticity.
According to the application range, PVC can be divided into: general type PVC resin, high polymerization PVC resin, crosslinked PVC resin.
Universal PVC resin is formed by polymerization of vinyl chloride monomer in the action of initiator;
High polymerization degree PVC resin is a resin added into the polymerization system of vinyl chloride monomer.
Crosslinked PVC resin is a resin composed of crosslinking agent containing diene and polyene in the polymerization system of vinyl chloride monomer.
According to the method of obtaining the polyvinyl chloride monomer, it can be divided into two categories: calcium carbide method, ethylene method and imported (EDC, VCM) monomer method (ethylene method is used as ethylene method).
According to the polymerization method, polyvinyl chloride can be divided into four types: suspension method polyvinyl chloride, emulsion method polyvinyl chloride, body method polyvinyl chloride, solution method polyvinyl chloride.
Suspension method polyvinyl chloride is the largest variety of production, accounting for about 80% of PVC production.
The suspension method is divided into six models with absolute viscosity: xs-1, xs-2...
XS - 6;
XJ - 1, XJ - 2...
, XJ - 6.
The meaning of each letter in the model: X - suspension method;
J - tight type.
According to the amount of plasticizer, PVC plastic is often divided into: no plasticized PVC, the content of plasticizer is 0;
Rigid PVC, the plasticizer content is less than 10%;
Semi-rigid PVC, plasticizer content is 10-30%;
Soft PVC, the plasticizer content is 30-70%;
Polyvinyl chloride paste plastic, the plasticizer content is more than 80 %.
