Natural advantages of PVC products1. A terrible fire
For many years, people have considered PVC to be a man-made note that is not harmonious in nature and that it destroys the environment and is not conducive to ecological development. In 1996, there was a sensational fire that killed 17 people at Dusseldorf Airport. Some wrong public opinion made people regard PVC as the culprit of this fire, which undoubtedly increased people's misunderstanding of PVC. .
Second, beautiful appearance
The surface and shape of the goods will leave a first impression. Advertising psychologists believe that this first impression plays a decisive role in product sales. 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. In the European and American countries, PVC is The darling of the construction industry, PVC is everywhere in people's daily lives. PVC can express not only the colors of nature, but also the colors that people imagine. In Germany, 40% of the furniture is made of PVC as the surface material. No one sees those natural colors, gorgeous colors, rich and diverse, beautiful patterns, elegant and elegant high-end desks, bookshelves, sofas, kitchen cabinets. They will be associated with the "white trash" on the streets, and they will not think that it is the PVC blister film that gives them such a beautiful coat.
Three, perfect structure
So what exactly is PVC? The full name of PVC is Polyvinylchlorid, the main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, the production of PVC in Europe in 1995 alone was about one million tons, while its consumption was 6.3 million tons. In Germany, PVC production and consumption averages 1.4 million tons. PVC is being produced and applied worldwide with 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. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for the surface layer of floors, ceilings and leather, but because soft PVC contains softeners (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and not easy to preserve, so its scope of use is limited. Hard PVC does not contain softeners, so it has good flexibility, easy to form, not brittle, non-toxic and non-polluting, and has a long storage time, so it has great development and application value. Hereinafter referred to as PVC. The essence of PVC is a vacuum blister film, which is used for surface packaging of various types of panels, so it is also known as decorative film, adhesive film, and is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounted for the largest proportion of 60%, followed by the packaging industry, as well as several other industries with small scope of application.
Fourth, strict craftsmanship
There 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 other is the 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. A film of 0.3 mm to 0.7 mm is printed at the same time as the production and printed on the front side of the film 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 made 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. The biggest problem with ordinary masks is that they cannot solve the problem of 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.
Five, extraordinary performance
What is the difference between PVC film and ordinary adhesive film? The ordinary adhesive film is directly glued on the surface of the board at room temperature, so after one or two years, the film is easy to fall off. The PVC film is applied to the surface of the board at a high temperature of 110 degrees using a special vacuum film pressing machine, so it is not easy to fall off.
Although PVC film has excellent quality assurance, some people may say that PVC is a chemical product after all, it is inferior to natural materials, it cannot eliminate toxicity and odor, and it will inevitably cause damage to the environment. This is not the case. This is because the raw materials for the PVC film produced in Germany are specially refined, and the toxic substances are completely refined. Therefore, PVC is completely non-toxic and tasteless, without any stimulation to the human skin or respiratory system. For people who are allergic to wood and paint, furniture or kitchen utensils packed with PVC film are very suitable. By using PVC film as a decorative film, people can use a large number of medium-density board, particle board, plywood and fiberboard to reduce the amount of wood used, thereby reducing the 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 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 not inferior to other alternatives, and the cost is cheaper than these materials. Relevant experts have found through research that in many industries, abandoning the use of PVC will incur considerable additional costs. Specific data shows that the abandonment of PVC will increase the additional cost of billions of marks. For specific consumers, this would mean a huge extra expense. Taking windows with PVC as the surface material, for example, if these windows do not use PVC, but ordinary wood is used as the surface layer, then only the cleaning and maintenance items will increase the amazing cost. In a small town in the UK, people have used wooden windows for the past two decades. Someone has investigated the cleaning and maintenance costs of these windows and compared them with the cleaning costs of PVC windows. The cleaning cost of ordinary windows is double that of PVC windows.
Six, a bright future
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 with its superior and unique performance. Yes, social development needs it and environmental protection needs it. It is an inevitable trend of the progress of our 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 (excluding heavy metal materials) environmental protection material so small? Of course, there are problems 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.
