You must know plastic? A product that is inseparable from all aspects of our lives. It may be the product's packaging or the product itself. At the beginning, its appearance has been greatly affirmed, convenient and durable, and it is an "excellent" Product, but with the development of the times, its disadvantages gradually began to appear, the most prominent is "white pollution."
Because plastic is an important organic synthetic polymer material, it is widely used. However, the "white pollution" caused by waste plastics is also getting more and more serious. If we can understand the composition and classification of plastics in detail, it will not only help us use plastic products scientifically, but also be helpful for the classification and recycling of plastics, and effectively control and reduce "White pollution".
People are now gradually realizing the importance of environmental protection, so they are slowly beginning to abandon their previous products.
Do you know what Teflon is? This raw material is called "the king of plastics", is it the same thing as traditional plastics, such as its product polytetrafluoroethylene molding material, can this board be directly understood as a plastic board?
Let ’s take a closer look together. This sheet is a polymer compound made from tetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealability, high lubricity and non-stickiness, electrical insulation and good Anti-aging endurance.
These excellent properties are not available in traditional plastics, and this product is used in atomic energy, national defense, aerospace, electronics, electrical, chemical, machinery, instrumentation, instrumentation, construction, textile, metal surface treatment, pharmaceutical, medical, textile, It is widely used in food, metallurgical smelting and other industries as high and low temperature resistant, corrosion resistant materials, insulating materials, anti-stick coatings, etc. It has become an irreplaceable product.
The reason why a product will be widely used and continuously developed is the inevitable factor.
