The main component of PVC is polyvinyl chloride, which is yellowish translucent and shiny. Transparency is better than polyethylene, polypropylene, and is different from polystyrene. It is divided into soft and hard polyvinyl chloride according to the amount of additives. The soft products are soft and tough, and the hand feels sticky. The hardness of hard products is higher than that of low density polyethylene. Below polypropylene, whitening occurs at the bend. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace one hydrogen atom in polyethylene.

So what exactly is PVC? PVC, the full name of Polyvinylchlorid, is mainly composed of polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive. It is a well-loved, popular and widely used synthetic material 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, and its consumption was 5.3 million tons. In Germany, the production and consumption of PVC is an average of 1.4 million tons. PVC is being produced and applied worldwide at a rate of 4%. The growth of PVC in Southeast Asia is 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.

The reason why PVC can be widely used in the building materials industry is two important reasons: First, the unique properties of PVC (rain, fire, antistatic, easy to form), and second, 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.

In most cases, bleaching is only a remedy and not a routine step in refurbishment. If the surface of the wood has obvious stains, dark spots or water stains; if the spots on the wood are spotted, it is covered with stains; if the color is uneven; or the old colorant is removed, there are still old spots and fillings on the PVC cabinet film. Agent, then PVC cabinet film needs to be bleached. Let's take the bleaching PVC cabinet film as an example to talk about the bleaching step of the PVC cabinet film.
