PVC Wall Of Small Knowledge

   With the advent of the decoration season, more and more pro who are engaged in the decoration of their new home. Many pro will come into contact with the term pvc wallboard. So what is pvc? What are the advantages of pvc wallboard? Here is the introduction of pvc wallboard, do not understand the pro who may follow Xiaobian together to understand the next pvc wall panels.PVC Wall Panels

    A thermoplastic resin obtained by polymerizing vinyl chloride under the action of an initiator. Is the homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer collectively referred to as vinyl chloride resin. PVC is an amorphous structure of the white powder, the degree of branching is small. Industrial production of PVC molecular weight is generally in the range of 50,000 to 12 million, with a large polydispersity, molecular weight increases with the reduction of polymerization temperature; no fixed melting point, 80 ~ 85 ℃ began to soften, 130 ℃ into a viscous state , 160 ~ 180 ℃ began to change to viscous flow; have good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ / m2; excellent dielectric properties.

    But the stability of light and heat is poor, above 100 ℃ or prolonged sun exposure, it will decompose and produce hydrogen chloride, and further automatic catalytic decomposition, causing discoloration, physical and mechanical properties are rapidly declining, in practice must be added to the stability To enhance the stability of heat and light. PVC is very hard, the solubility is also very poor, can only be dissolved in cyclohexanone, dichloroethane and tetrahydrofuran and a few solvents, the organic and inorganic acids, alkali, salt are stable, chemical stability with the use of temperature And lower. PVC dissolved in acetone - carbon disulfide or acetone - benzene mixed solvent for dry spinning or wet spinning from fiber, called polyvinyl chloride. With flame retardant, Naisuan Jian, anti-microbial, wear and has a good warmth and flexibility.PVC Wall Panels
