Plastic products are very common in our daily life, and our lives are becoming more and more inseparable from plastics. Even the houses we decorate have many plastic windows. PVC material is a kind of plastic product, but this kind of plastic product has the value of recycling, and this kind of product is also widely used in life. Many household appliances are made of it. So is PVC material harmful to the human body? Qualified PVC chairs will not cause harm to your body when used. Products with strong and bad odors are inferior products, so please use them with caution. Generally, plastic products will have some odor, which will usually disappear or decrease after some time of normal use. The harm of PVC mainly occurs during the production process and the waste recycling process, and it does not cause direct harm to consumers.PVC material is polyvinyl chloride, which is one of the world's largest-produced plastic products. It is cheap and widely used. Polyvinyl chloride resin is a white or light yellow powder and cannot be used alone but must be modified. PVC is a white powder with an amorphous structure, a small degree of branching, and poor stability to light and heat. Different additives can be added according to different uses, and polyvinyl chloride plastics can exhibit different physical and mechanical properties. By adding an appropriate amount of plasticizer to polyvinyl chloride resin, a variety of hard, soft and transparent products can be made. PVC, the full name is Polyvinylchloride, the main component 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 back-coated adhesive. It is a synthetic material that is very popular, widespread and widely used in the world today. Its global usage ranks second among various 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, the production and consumption of PVC averages 1.4 million tons. PVC is being produced and used worldwide at a growth rate of 4%. The growth rate 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. PVC is polyvinyl chloride, a plastic product synthesized from 43% oil and 57% salt. Compared with other types of plastic products, PVC uses raw materials more efficiently and reduces fuel consumption. At the same time, the energy consumption of PVC manufacturing is also very low. And at the end of the use of PVC products, they can be recycled and converted into other new products or incinerated to generate energy. |
