There are many PVC material boards with various effects. Why can PVC hard boards completely replace wood and become the wood of the future? This starts with its advantages. Compared with wood, what are the outstanding advantages of PVC rigid board?

First of all, compared with wood, pvc hard board itself has good chemical stability, corrosion resistance, high hardness, high strength, and high strength. Therefore, in construction, it improves the disadvantages of wood being easy to deform and corrosion, and the use effect is very outstanding. .

Secondly, compared with wooden materials, hardboard has the characteristics of moisture-proof, anti-corrosion, insect-proof, flame-retardant, no need to paint, non-toxic and tasteless, and also anti-termite, so its use can not only save wood, but also effectively improve people's living. The environment is high-quality indoor and outdoor building materials.

Third, the transparent board in the rigid board is mainly used for packaging materials and windows of machinery and equipment, and can replace glass in some occasions, and the colored decorative board is mainly used as electronics, communication and decoration materials. The application of wood is limited by its own physical characteristics and is not wide enough.

Fourth, as a thermoforming material, pvc hard plate can replace some stainless steel and other corrosion-resistant synthetic materials. It is widely used in chemical, petroleum, electroplating, water purification treatment equipment, environmental protection equipment, mining, electronics, communications and decoration industries. .

From the above four advantages, it can be seen that the performance of pvc rigid board is very good, so it is liked by users in various industries, and fortunately its advantages in various aspects allow it to replace wood in a complete sense. This not only improves the efficiency of the industry, increases the performance of products, but also reduces the waste of wood. It is a very good material choice for the economy and society.

PE film, namely polyethylene film. Polyethylene plastics are divided into high density, medium density and low density. Generally linear low density polyethylene Density: 0.91—0.965g/cm3 (g/cm3). The density of low density polyethylene is about 0.92g/cm3. Low-density polyethylene film has good transparency and heat-sealability, and can be waterproof and moisture-proof; low tensile strength, high tensile elongation, easy to wrinkle, film below 0.03mm, the tension control should be small, and the tension everywhere It should be constant, especially when it is heated, it is more likely to be deformed, causing difficulty in color registration. Therefore, when drying, the surface temperature of the film should not be too high (within 550C). According to the different film forming process, it can be divided into blown film (IPE), cast film (CPE), low foaming film and so on. The tensile strength and opening of IPE film are better than CPE film, and it can be used for food bags, clothing bags, etc. with front printing; CPE film has uniform thickness, better surface gloss, transparency and heat sealability than PE, and can be printed on both sides. But the production cost is high. The CPE film is mainly used as the inner layer of the composite bag and the packaging of cosmetics, pickles and cakes; the low-foaming film has good decorative properties, thick texture, and is not easy to be stretched and deformed. The density of medium density polyethylene is about 0.93 ~ 0.94g/cm3, and its performance is between high density and low density polyethylene. The density of high-density polyethylene is 0.94—0.965g/cm3. The heat resistance and mechanical strength of high-density polyethylene film are better than that of low-density polyethylene film, and the tensile elongation is small. The film thickness is generally above 0.03mm, but the transparency is poor. With front printing, it is mainly used as vest bag, garbage bag and liner bag, etc.
