PVC is widely used in building materials industry
PVC is widely used in building materials industryThere are two important reasons why PVC can be widely used in the building materials industry:
One is the unique properties of PVC (rainproof, fire resistant, antistatic, easy to form), and the second is the characteristics of low input and high output of PVC. So, why can PVC have the above two advantages? Let us find the answer from its production process.
The production process of PVC is not complicated. The ordinary production line is generally composed of a roller press, a printing machine, a back coater and a cutting machine. It is mainly produced by the direct motion stirring of the roller press, the rotation of the roller and the high temperature rolling. Films with a thickness of 0.3 mm to 0.7 mm are printed on the front side of the film at the same time of production and by a printing machine, and a layer of back coat is attached to the back of the film by a back coater. Don't underestimate this layer of back coating, it is an important guarantee for the high quality performance of PVC film. The back coating is composed of special materials and is a kind of high-energy affinity agent. It is precisely because of this layer of back coating that the PVC film can be tightly fused with the medium-density board or other boards. It will not be glued for ten or even fifteen years. The biggest problem with ordinary face masks is that they cannot solve the problem of film shedding. Since the entire production process is carried out at high temperature (the temperature in the roller press reaches 220 degrees), this makes the PVC film with high light resistance and fire resistance, ensuring the high quality of the PVC film. Of course, this has high requirements for production machines. Usually, the production cost of a production line is about 39 million marks, which is equivalent to about 160 million yuan. But on the other hand, the production process of PVC film is quite simple, and the output of the machine is also very large, so from a comprehensive perspective, PVC is actually a product with low input and high output.
good prospect forecast
At present, the PVC industry is developing rapidly all over the world, with broad prospects. All countries are optimistic about the potential of PVC and its benefits to the ecological environment. PVC is proving to the world that its role and status are superior to any other product at present with its superior and unique properties. Yes, social development needs it and environmental protection needs it. It is an inevitable trend of the progress of our human social civilization.
As the world's PVC industry is booming, unfortunately, our domestic PVC furniture materials (including cabinets) account for less than 10% of the market. Many consumers have not even heard of PVC as a furniture material, let alone know What is PVC. Why is the domestic market share of German PVC film as a high-grade, non-toxic and non-polluting (without heavy metal materials) environmental protection material still so small? There is of course a problem at the consumer level, but it is mainly related to the lack of correct understanding of PVC by our consumers. It restricts the production volume of PVC membrane furniture, and thus cannot form a scale. I believe that through the joint efforts of our peers and the maturity of the market, the PVC industry will definitely reach a new level in the field of furniture.
PVC foam board: It has the characteristics of anti-corrosion, moisture-proof, mildew-proof, non-absorbent, drillable, sawable, planable, easy to thermoform, hot bending, etc., so it is widely used in furniture, cabinets, bath cabinets, exhibition shelf boards , Cabinet core layer, indoor and outdoor decoration, building materials, chemical industry and other fields, advertising signs, printing, silk screen, inkjet, computer lettering, electronic instrument product packaging and other industries
PVC rigid plastic board: has excellent corrosion resistance, insulation, and has a certain mechanical strength; after secondary processing can be made into sulfuric acid (hydrochloric acid) tank (barrel box); empty needle rack for medicine, chemical rack; Public toilet water tank; all kinds of special-shaped products and containers such as template for processing products, decorative plates, exhaust pipes, equipment lining, etc. It is an ideal material for chemical industry, building materials, decoration and other industries
