What are the characteristics of PVC, the role?
PVC (polyvinyl chloride), the simple structure of its monomer CH2 = CHCl Chemical and physical properties: Rigid PVC is one of the most widely used plastic materials.PVC is actually a vinyl polymer, its material is a non-crystalline material.PVC material in the actual use of often added stabilizer, lubricant, auxiliary processing agent , Colorants, impact agents and other additives. Has a non-flammability, high strength, weather resistance and excellent geometric stability of PVC on oxidants, reducing agents and strong acid has a strong resistance, but it can Strongly oxidized acid such as concentrated sulfuric acid, concentrated nitric acid corrosion and does not apply with aromatic hydrocarbons, chlorinated hydrocarbons in contact with the occasion. PVC melting temperature during processing is a very important process parameter, if this parameter will lead to improper decomposition of the material. PVC flow characteristics are quite poor, its process range is very narrow. Especially large molecular weight PVC material is more difficult to process (this The material is usually added to the lubricant to improve the flow characteristics), so usually used are small molecular weight PVC material PVC shrinkage is quite low, generally 0.2 to 0.6%.
Wardrobe sliding door with health wood and PVC which is good? How big is the price difference? Please list the advantages and disadvantages separately.
Wardrobe sliding door is now very commonly used is the wood-plastic board, wood-plastic board paste pvc can do and the same color of the wardrobe, wood plastic, then mainly as wood raw materials and extrusion additives are environmentally friendly, pvc, then basically The same, the difference is not too big, the key is to paste pvc glue is environmentally friendly.

Aluminum foil, commonly known as foil, aluminum foil, etc., is a flattened metal aluminum manufacturing tools, mainly for kitchen cooking, containing food, or used to make some simple and clean materials. Thousands of tons of aluminum foil are used throughout the world for the protection and packaging of food, cosmetics and chemicals. Most of the aluminum foil is bright and the other side is gray and dumb. Food with aluminum foil can be wrapped in both sides of food, usually recommended to bright side wrapped, enhance the heat conduction effect.

What is the difference between PVC integrated wallboard and wood fiberboard?
First of all their material is not the same. One is PVC, one is bamboo fiber.
PE wood and PVC wood plastic which is cheaper, what is the difference between appearance
PE wood plastic products features: 1, heat is easy to deformation, but the use of thickening or porous hollow results better, in terms of water resistance and corrosion resistance has a good effect 2, the product of a single color, no wooden feel beautiful effect is very poor, antioxidant and Kang light decomposition is poor, that is, adding antioxidant and absorbent effect is not ideal, this can cause product strength and color fastness Is not good, the product of the outdoor life is shorter Pvc wood-plastic products features: 1, pvc can be a variety of secondary surface decoration or paint, the product is beautiful and good color fastness, but also has a waterproof anti-corrosion 2, can be made of foam wood products, so that the lower cost at the same time using the common way, strength and wood texture are very good, the product can be used as a new material or the old material to do, modification is also easier to fill Depends on the quality of the product.
What are the advantages and disadvantages of the pvc wallboard?
PVC material wallpaper can be fully customized according to product design requirements, the output rich color, texture and diverse, colorful. With the wallpaper technology continues to improve, and gradually have a more extensive use. And the price is relatively low, by the vast number of consumers generally welcomed.
