PVC Profile a terrible fire many years, people think PVC is an artificial nature discordant note, that it destroy the environment is not conducive to ecological development. 1996 in Dusseldorf airport there was a hit, so Seventeen people were killed in the fire, some public opinion to make the wrong people to PVC as a culprit in the fire, and it will increase the misunderstanding of the PVC . Second, surfaces and shapes give people the beautiful appearance of the goods first impression. Advertising psychologists believe that this first impression for the marketing of products plays a decisive role. From this layer sense, the market is very optimistic about the prospects for PVC film. In fact, with the development of the times, PVC is also its good performance, simple process and many other advantages of gradually won the hearts and minds of the people, more and more people have been accepted and recognized in the United States and Europe is PVC construction industry darling, PVC in people's daily life everywhere. PVC can be expressed not only the nature of color, you can also show people the illusion of color. In Germany, 40 percent of the furniture is made of PVC to make the surface of the material, see the natural color, color gorgeous, rich and varied, beautiful patterns, elegant and upscale style desk, bookshelves, sofas, cabinets, who do not who will take them and street devastated "white trash" to associate together, would not think it is PVC plastic film gives them such a beautiful coat. Third, the perfect structure that PVC in the end what is it? PVC, full name Polyvinylchlorid, the main component of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top layer mask is painted, the main ingredient in the middle of the PVC, the lower is the adhesive-backed. It is loved by the world, is quite popular and is also widely used as a synthetic material. It ranks second in the global use of a variety of synthetic materials. According to statistics, in 1995 only a year, not in the production of PVC in Europe have about five million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption by an average of 1.4 million tons. PVC is the growth rate of 4% of the production and application worldwide. In recent years, growth in the number of PVC in Southeast Asia is particularly significant, thanks to the Southeast Asian countries have carried out urgent infrastructure needs. In the three-dimensional surface film can produce materials, PVC is the most suitable material. PVC can be divided into soft PVC and rigid PVC. Hard PVC market which accounts for about two-thirds of soft PVC 1/3. Soft PVC are generally used for surface floors, ceilings and leather, but because of soft PVC containing softener (which is soft PVC and rigid PVC difference), easy to become brittle and difficult to save, so its use has been limited. Hard PVC free softener, so flexible, easy molding, hard brittle, non-toxic and pollution-free, save for a long time, so it has great development and application value. Below are referred to PVC. PVC is essentially a vacuum plastic film for packaging various types of panel surface, it is also known as decorative films, with film, used in building materials, packaging, pharmaceutical and other industries. Building materials industry accounted for the largest proportion, 60%, followed by industry, packaging industry, there are a number of other small-scale applications. Fourth, strict process PVC reason can be widely used in building materials industry, there are two very important reasons: First, the unique properties of PVC (rain, fire-resistant, anti-static, easy molding), and second, low investment and high PVC Features production. So, PVC can have these two excellent why it? Let us now find the answers come from the production process. PVC production process is not complicated, general production line generally consists of rolling machines, printing presses, back coating machine and cutting machine components, mainly through direct action stirring rolling machine, roller rotation and high temperature to produce a thickness of only rolling of 0.3 mm to 0.7mm film, produced by the press at the same time and the front color printed film, by back coating machine attached to a layer on the back of the back coating film. Do not underestimate this layer back coating, it is an important guarantee for high-quality PVC film properties. Back coating made of special material, is a high-energy affinity agents, it is precisely because of this layer back coating, PVC film to close tightly and the board or other sheet together, ten or even fifteen years not open plastic. Ordinary paste mask the biggest problem is not solve the problem of falling film. Because the entire production process is at a high temperature (rolling machine inside temperature reaches 220 degrees) carried out, which makes PVC film with high resistance to light and fire resistance, ensuring a high quality PVC film. Of course, this is very high demands on the production machine, usually a set of production line equipment cost about 39 million marks, equivalent to about 160 million yuan. But on the other hand, the production process is quite simple PVC film, machine production is also great, so comprehensive look, PVC is actually a low-input, high-volume products. Five exceptional performance PVC film with ordinary paste film, what difference will it make? Ordinary paste film is directly attached with glue at room temperature on the surface of the plate, so after a couple of years, it is easy to fall off foil. The PVC membrane is application-specific vacuum laminator at a high temperature of 110 degrees pressure plate attached to the surface, so easy to fall off. Although PVC film has excellent quality assurance, but some might say, PVC, after all, a chemical product, it is not as natural materials can not be excluded toxicity and odor, they will inevitably harm the environment. This is not true, because the German production of PVC membrane material is refined through a special, toxic substances are completely extracted, so the PVC is completely non-toxic and tasteless to human skin or respiratory system without any stimulation, for those people allergic to wood and paint, the use of PVC film packaging of furniture or kitchen is very appropriate. By using PVC film for decorative film, people can use a lot of dense, particle board, plywood and fiberboard, reduce the use of timber volume, thereby reducing damage to forests and the environment. From this perspective, PVC film to protect the ecological environment has made a great contribution. The use of PVC in Western countries once caused a great controversy, many people tried to use various other materials instead of PVC. But the fact is, PVC mass ratio favorably compared to other alternatives, but it is cheaper than the cost of these materials. Experts study found that in many industries, renounce the use of PVC will produce a significant number of additional costs. Specific data indicate that the use of PVC will forgo additional cost several billion mark. For specific consumers, this will mean a huge additional expenditure. To use as a surface material PVC windows, for example, if these windows do not use PVC, but the use of wood as a general surface, then just cleaning and maintenance of an alarming number will increase costs. In a small town in England, people in the past two decades are using wooden windows, someone to clean the windows of the maintenance costs were investigated, and to compare it with the cost of PVC windows clean, and the results showed that wood ordinary window cleaning system costs higher than the cost of cleaning the windows PVC double. Six bright future PVC industry is currently developing rapidly in the world, prospects, countries are optimistic about the potential of PVC and its benefits to the ecological environment, PVC is its superior performance prove its unique role and status is currently no Other products can not be replaced, it needs social development, environmental protection need it, it is an inevitable trend of our civilization and progress of human society. As the world when PVC industry flourishing, but unfortunately, in our domestic PVC furniture materials (including cabinet) market share of less than 10%, many consumers have not even heard of PVC as a furniture material, but I do not know PVC are. Why Germany PVC film as a high-grade, non-toxic and pollution-free (non-heavy metal materials) eco-friendly materials in the domestic market share is still so small it? Here, of course there is the problem of consumption levels, but mostly with our consumers PVC lack of proper understanding of this material related. It enables the production of PVC film furniture is limited, and thus can not form scale. I believe that through the joint efforts of our peers, the market matures, PVC industry must at a new level in the field of furniture. PVC foam board: with anti-corrosion, moisture, mold, non-absorbent, drilling, sawing, planing, easy thermoforming, hot bending and other characteristics, it is widely used in furniture, cabinets, Cabinet, exhibition stand with board , box core, interior decoration, building materials, chemical industry panels, advertising labeling, printing, screen printing, printing, computer lettering, electronic instrumentation products and packaging industries PVC hard plastic plate: excellent corrosion resistance, insulation and there is a certain degree of mechanical strength; after secondary processing can be made of sulfuric acid (hydrochloric acid) tank (tank barrels); medicine with an empty needle holder, of the drive frame; public health tank; template processing products, decorative plates, exhaust piping, equipment, and other kinds of special products lining the container. Ideal for material chemicals, building materials, decoration and other industries plexiglass: With good weather resistance, impact resistance, high transmittance, quality easy to install, plasticity strong character. In construction, decoration, advertising and other industries are widely used.
