PVC wallpaper—PVC profile
PVC is polychlorinated (same as “green”) ethylene, and English is abbreviated as PVC (Pol*vin*l chloride), and is a vinyl chloride monomer (Vinyl chloride monomer, VCM for short) initiated in peroxides, azo compounds, etc. Agent; polymerized by a free-radical polymerization reaction mechanism under the action of light and heat. Chloroethylene homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. Its material is a non-crystalline material. In practice, PVC materials often include stabilizers, lubricants, auxiliary processing agents, colorants, impact agents, and other additives. With non-flammability, high strength, weather resistance and excellent geometric stability. PVC is very resistant to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, and is not suitable for applications in contact with aromatic hydrocarbons and chlorinated hydrocarbons.
PVC Wallpaper - Kind of PVC Wallpaper
A. Common type: 80g/m2 paper is used as paper base, and 100g/m2 PVC resin is applied on the surface. The surface decoration method is usually a combination of printing, embossing, or printing and embossing.
B. Foaming type: 100 g/m2 paper is used as paper base, and the surface is coated with 300-400 g/m2 PVC resin. According to the size of the expansion ratio, there are low foaming and high foaming, respectively. The surface of high-foaming wallpaper is elastic and has a certain sound-absorbing effect.
C. Functional type: Among them, water-resistant wallpaper is made of glass fiber cloth as the base material, which can be used to decorate the walls of bathrooms and bathrooms; fireproof wallpaper is made of 100-200g/m2 asbestos paper and mixed in PVC face material. Into the flame retardant.
