Appearance variety
In this sense, the market prospect of PVC film is very promising. Along with the development of the era, PVC is with its good performance, simple process and many other advantages gradually won the favor of people, has been more and more people have accepted and approved, is the darling of the construction industry in the European and American countries PVC, PVC can be found everywhere in People's Daily life. PVC can represent not only the color of nature, but also the color of people's imagination. In Germany, 40% of the furniture are made of PVC for the surface material, see the colour and lustre is natural, colorful, diverse, beautiful patterns, style elegance and luxury desk, bookcase, sofa, hutch ark, who also won't put them and street devastated "white trash" lenovo together, more not think it is PVC blister film give them such beautiful coat.
Process strictly
PVC can be widely used in building materials industry, there are two important reasons: one is the PVC unique performance (waterproof, fireproof, anti-static, easy molding), the second is the characteristics of PVC low investment and high yield. PVC film has high resistance to light and fire, ensuring high quality of PVC film. Therefore, from a comprehensive perspective, PVC is actually a low input and high output product.
Melting temperature: 185 ~ 205 ℃ mold temperature: 20 ~ 50 ℃
Injection pressure: it can be up to 1500bar pressure: it can be up to 1000bar infusion speed: in order to avoid material degradation, it is generally necessary to use a considerable injection speed.
Runner and gate: all conventional gates are available. If smaller parts are processed, it is best to use needle-tip gate or submersible gate. For thicker parts, it is best to use fan gate. The minimum diameter of needle tip gate or submerged gate should be 1mm. The thickness of fan gate should not be less than 1mm.
Performance of the unique
What is the difference between PVC film and ordinary adhesive film? The normal adhesive film is used to stick glue directly to the surface of the board at room temperature, so after one or two years, the film will fall off easily. And PVC film is used special vacuum film press in 110 degrees of high temperature pressure attached to the surface of the plate, so it is not easy to fall off.
PVC is completely non-toxic tasteless, no stimulus to human skin or respiratory system, for those people who are allergic to wood and paint, using PVC membrane packing of furniture or kitchen utensils and appliances is very appropriate. Through the use of PVC film as a decorative film, people can have a lot to avoid using Micronesia board, particle board, plywood and fiberboard, decrease the use of timber, and thus to minimize damage to the forest and environment.
The use of PVC once caused great controversy in western countries. Many people tried to replace PVC with various other materials. But it turns out that the quality of PVC is no less than that of other alternatives, and it's cheaper to make than these materials.
Broad prospects
Wide prospect of PVC industry is developing rapidly all over the world, all countries on the potential of PVC and its benefits to the ecological environment, the performance of the PVC is its superiority, unique to the world that its role and status is any other products can replace, social development needs it, environmental protection need to it, it is the inevitable trend of our human society civilization progress.
