A: Introduction to PVC Materials
PVC and polyvinyl chloride are plastic products made from 43% oil and 57% salt. Compared with other kinds of plastic products, PVC uses raw materials more effectively and reduces fuel consumption. At the same time, the energy consumption of PVC manufacturing is also very low. And in the late use of PVC products, can be recycled and converted to other new products or incineration to obtain energy, PVC will be added in the production of stabilizers, but the stabilizers are non-toxic and toxic, only adding lead salts and the like Toxic stabilizers will cause hidden troubles. However, PVC products are mixed, and some small companies use lead salts as stabilizers, and it is difficult to meet relevant hygiene standards.
Second: PVC material application PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used on the surface of floors, ceilings, and leather. However, since soft PVC contains softener (which is also the difference between soft PVC and hard PVC), it tends to become brittle and difficult to store, so its use range is limited. Hard PVC does not contain softeners, so it has good flexibility, easy molding, is not brittle, non-toxic and non-polluting, and has a long storage time. Therefore, it has great development and application value. The essence of PVC is a vacuum-absorbing film, which is used for surface packaging of various types of panels. Therefore, it is also known as a decorative film, attached film, and is used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for the largest proportion, which is 60%, followed by the packaging industry, as well as other small-scale applications.
In this sense, the market prospect of PVC film is very promising. With the development of the times, PVC is gradually gaining people's favor with its good performance, simple process and many other advantages. It has been accepted and recognized by more and more people. PVC is a construction industry in Europe and the United States and other countries. Beloved, PVC can be seen everywhere in people's daily life. PVC can not only represent the natural color, but also can represent people's fantasy colors. In Germany, 40% of the furniture is made of PVC as the surface material, seeing those desks, bookshelves, sofas, kitchen cabinets with natural colors, gorgeous colors, rich and varied, beautiful designs, and elegant styles, no one It would associate them with the devastated “white trash†on the streets, but it wouldn’t even be thought that it was the PVC blister film that gave them such beautiful coats.
Three: The perfect structure The main component of PVC is polyvinyl chloride, in addition to adding other ingredients to enhance its heat resistance, toughness, ductility and so on. It is a kind of synthetic material that is popular, popular, and widely used in the world today. Its global use ranks second among various synthetic materials. According to statistics, in 1995 alone, PVC produced about 5 million tons in Europe, and its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%. In recent years, the growth of PVC in Southeast Asia has been particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material.
Four: extraordinary performance PVC film and ordinary paste film What is the difference? Ordinary adhesive film is directly glued to the surface of the board at room temperature, so after one or two years, the film will easily fall off. The PVC film is applied on the surface of the sheet by applying a special vacuum laminator at a temperature of 110 degrees, so it is not easy to fall off. PVC is completely non-toxic and odorless, without any irritation to human skin or respiratory system. For those who are allergic to wood and paint, PVC film-packed furniture or kitchen utensils are very suitable. By using PVC film as a decorative film, people can avoid the use of dense plates, particleboards, plywood, and fiberboard in large quantities, reducing the amount of wood used, thereby reducing damage to the forest and the environment. The use of PVC was once caused in Western countries. The big controversy, many people try to use all kinds of other materials instead of PVC. However, it turns out that the quality of PVC is not inferior to other alternatives, but is cheaper than these materials in terms of cost.
V. Good prospects Currently, the PVC industry is developing rapidly in the world and has broad prospects. All countries are optimistic about the potential of PVC and its benefits to the ecological environment. PVC is demonstrating its role and status to the world with its superior and unique performance. No other product can replace it. Social development needs it. Environmental protection needs it. It is an inevitable trend of human civilization progress.
