ZHONGSHAN LINYANG PLASTIC CO.LTD small lecture hall is here today to explain the perfect structure of PVC blister film and its strict process knowledge, hoping to help everyone have a deeper understanding and understanding of PVC blister film. 1. Perfect structure So what exactly is PVC? PVC, the full name is Polyvinylchlorid, the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is a back coating adhesive. It is a well-loved, popular and widely used synthetic material in the world today. Its global usage is the second highest among all synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while 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. 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 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 difficult to store, so its scope of use is limited. Hard PVC does not contain softeners, so it has good flexibility, easy to form, not easy to be brittle, non-toxic and pollution-free, 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 the surface packaging of various panels, so it is also called decorative film and adhesive film, and is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, accounting for 60%, followed by the packaging industry, and several other industries with small-scale applications. 2. Strict craftsmanship The reason why PVC can be widely used in the building materials industry has two important reasons: First, the unique properties of PVC (rainproof, fire-resistant, anti-static, easy to form), and the second is the low investment of PVC and high yield characteristics. So, why does 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 rolling machine, a printing machine, a back coater and a cutting machine. It is a 0.3mm to 0.7mm film, which is produced at the same time and is printed on the front side of the film by a printing machine, and a backcoat is attached to the back side of the film by a backcoater. But 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 composed of special materials and is a high-energy affinity agent. It is precisely because of this back coating that the PVC film can be tightly integrated with the MDF or other boards, and it will not be glued for ten or even fifteen years. The biggest problem of ordinary veneer is that it cannot solve the problem of film falling off. Since the whole production process is carried out at high temperature (the temperature in the rolling machine reaches 220 degrees), this makes the PVC film have 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 cost of production equipment for a production line is about 39 million marks, equivalent to about 160 million yuan. On the other hand, the production process of PVC film is quite simple, and the output of the machine is also large. Therefore, from a comprehensive perspective, PVC is actually a low-input, high-yield product. Zhongshan ZHONGSHAN LINYANG PLASTIC CO.LTD Decorative Materials Co., Ltd. was established in 2003.
