Introduction of PVC material

A terrible fire

For many years, people believed that PVC was a man-made note in disharmony in nature, and it was believed that it destroyed the environment and was not conducive to ecological development. In 1996, a sensational fire took place in Düsseldorf airport, killing 17 people. Some false public opinion led people to regard PVC as the culprit of the fire. This undoubtedly increased the misunderstanding of PVC. .

Second, beautiful appearance

The surface and shape of the goods will give a first impression. Advertising psychologists believe that this first impression plays a decisive role in the sales of products. In this sense, the market prospect of PVC film is very promising. In fact, 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 used in European and American countries. The darling of the construction industry, 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.

Third, the perfect structure

So what exactly is PVC? PVC, full name is Polyvinylchlorid, the main ingredient is polyvinyl chloride, in addition to adding other ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is lacquer, the main ingredient in the middle is polyvinyl chloride, and the lowest layer is back-coated adhesive. 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 production in Europe was about 5 million tons, while its consumption was 5,300,000 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.

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. Hereinafter referred to as PVC. 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.

Fourth, strict process

The reason why PVC can be widely used in the building materials industry is two important reasons:

One is the unique performance of PVC (rainproof, fireproof, antistatic, and easy to mold), and the second is the low input and high output of PVC. So why can PVC have the above two advantages? Let's look for the answer from its production process.

The production process of PVC is not complicated. The common production line is generally composed of a roller press, a printing machine, a back coater and a cutting machine, and is mainly produced through the direct-acting stirring of a roller press, the rotation of a roller, and the high temperature rolling to produce a thickness of only For a film of 0.3 mm to 0.7 mm, the color is printed on the front surface of the film at the same time and by the printing machine, and a back coat is attached to the back of the film by a back coater. Do not underestimate this layer of back coating, it is an important guarantee for the quality of PVC film. The back coating is composed of special materials and is a kind of high-energy affinity agent. Because of this back coating, PVC film can be tightly integrated with the middle dense plate or other plate materials. It does not open glue in ten years or even fifteen years. The biggest problem with ordinary veil is that it cannot solve the detachment of the film. Because the entire production process is carried out at a high temperature (the temperature inside the roller press reaches 220 degrees), this makes the PVC film have high light resistance and fire resistance, and ensures the high quality of the PVC film. Of course, the requirements for production machines are very high. Usually the production cost for a production line is about 39 million marks, equivalent to about RMB 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. Therefore, in a comprehensive view, PVC is actually a product with low input and high output.

Five, extraordinary performance

What is the difference between the PVC film and the ordinary film? Ordinary film is glued directly to the surface of the board at room temperature, so after one or two years, the film will fall off easily. 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.

Although the PVC film has excellent quality assurance, some people may say that PVC is a chemical product after all. It is inferior to natural materials, and cannot eliminate toxicity and odor, and it will inevitably cause harm to the environment. This is not the case, because Germany's raw materials for the production of PVC film are specially refined, and toxic substances are completely extracted. Therefore, PVC is completely non-toxic and odorless, without any irritation to the human skin or respiratory system. For those who are allergic to wood and paint, PVC film wrapped furniture or kitchen utensils are very suitable. By using a PVC film as a decorative film, people can use a large number of middle plates, particleboards, plywood, and fiber boards to reduce the amount of wood used, thereby reducing damage to the forest and the environment. From this perspective, PVC film has made a great contribution to the protection of the ecological environment.

The use of PVC was once very controversial in Western countries. Many people tried to replace PVC with various other materials. 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. Relevant experts have found through research that in many industries, giving up the use of PVC will generate considerable additional costs. The specific data shows that giving up the use of PVC will increase the additional cost of several billion marks. For specific consumers, this will mean a huge extra expense. In the case of windows with PVC as the surface material, if these windows do not use PVC, but use ordinary wood as the surface layer, then only the cleaning and maintenance of an item will increase the alarming cost. In a small town in the UK, people have used wooden windows for the past two decades. Some people have investigated the cost of cleaning and maintenance of these windows and compared them with the cost of cleaning PVC windows. The results show that wood The cost of cleaning ordinary windows is twice as high as that of PVC windows.

Sixth, a bright future

At present, 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. At present, no other product can replace it. Yes, social development needs it, and environmental protection needs it. It is an inevitable trend of the progress of human civilization in our society.

Note:

Germany is a showcase of PVC products. Its production process has a long history and rich experience, and it is a world leader. In terms of cabinets alone, PVC materials account for 75% of the market. The German company Renolit is one of the largest PVC producers in the world. Renault-Werke, a subsidiary of the Renolit Group, has 16 production sites and more than 2,000 employees worldwide. Its production of PVC film is known for its excellent quality. Shanghai Desil Trading Co., Ltd. is the general agent of Renolit Greater China and is solely responsible for all sales of Renolit in the Greater China Region. The company's unity and unity, work together, strictly pursue the purpose of the supremacy of customer interests, warm and thoughtful, dedicated to serve every customer.

While the PVC industry in the world is booming, unfortunately, in China, the market share of PVC furniture (including cabinets) is less than 10%. Many consumers have not even heard of PVC as a furniture material. What is PVC? Why is the German PVC membrane as a high-grade, non-toxic, non-polluting (excluding heavy metal materials) environmental protection materials still so small in the domestic market? There is of course a problem at the consumer level, but more importantly with our consumers. Lack of proper understanding of this material for PVC. It has limited the production of PVC film furniture and cannot be scaled. It is believed that through the joint efforts of our peers and the maturity of the market, the PVC industry will certainly reach a new height in the furniture field.
