PVC Material Advantages
1, the structure of the United States
What is pvc? PVC is a popular, popular and widely used synthetic material in the world today. Its global usage ranks second among all composites. According to statistics, in 1995 alone, PVC production in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC average 1.4 million tons. PVC is being manufactured and applied worldwide at a 4% growth rate. The growth of PVC in Southeast Asia in recent years is particularly significant due to the urgent need of all countries in Southeast Asia to carry out infrastructure construction. Among the materials that can produce three-dimensional surface films, PVC is a coherent material.
2, strict process
(1), PVC unique performance (rain, fire, anti-static, easy to shape). PVC production process is not complicated, the general production line generally by the roller press, printing press, back coating machine and cutting machine composition, mainly through direct rolling mill roller, roller rotation and high temperature rolling to produce only the thickness of 0.3 mm to 0.7 mm film, printed on the front of the film at the same time as it is produced by the printer, and a back coat applied to the back of the film by a back coater. Do not underestimate this layer of back coating, it is an important guarantee of high performance PVC film. Back coating is made of special materials, is a high-energy affinity agent, it is precisely because of this layer of back coating, PVC film can be closely integrated with the plate or other plate together, ten years or even do not open plastic. The general paste mask in the big problem is unable to solve the film off problem. Because the entire production process is carried out at high temperatures (220 degrees Celsius in the roller), this results in high lightfastness and fire resistance of the PVC film, ensuring the high quality of the PVC film.
(2), PVC low input high yield characteristics. pvc on the production machinery demanding, usually a production line equipment cost about 39 million marks, equivalent to about 160 million yuan. But on the other hand, PVC film production process is quite simple, the machine output is also very large, so a comprehensive view, PVC is actually a low input, high yield products.
3, extraordinary performance
PVC film is the application of special vacuum laminator at 110 degrees under high temperature pressure attached to the surface of the sheet, not easy to fall off. pvc is what material? The production of PVC film in Germany is a special extraction of raw materials, toxic substances are completely extracted, so PVC is completely non-toxic and tasteless, no stimulation of human skin or respiratory system, for those on wood and paint Allergic people, the use of PVC film packaging furniture or kitchen is very suitable. Through the use of PVC film as decorative film, people can use a large number of medium density boards, particleboard, plywood and fiberboard, reduce the amount of wood used, thereby reducing the damage to the forest and the environment. From this perspective, PVC membrane has made a great contribution to the protection of the ecological environment.
