How To Distinguish Between New Materials And Recycled Materials For Plastic Products
In real life, plastic products have penetrated into all aspects of our lives. Because we are not professional in the material properties of plastic products, we choose some products made of harmful materials, which brings harm to our lives and health. Modern scientific evidence shows that some chemicals in waste plastic products are chronically toxic, and long-term exposure can cause harm to the human body. Mainly polyvinyl chloride monomer, the main component of plastic, will damage the human nervous system, liver and kidneys after being absorbed, so we need to know a simple way to identify plastic products.
1. Through observation, we learned that brand-new plastic products have bright colors, high transparency, and no variegation. As for waste plastic products, the color is darker, the color is darker, and the patterns are more serious.
2. Understand through the sense of smell that products made of new materials have no peculiar smell. Products made from recycled materials have a peculiar smell.
3. Compare the weight and understand that for plastic products of the same size, new plastic products are lighter, while waste plastic products are heavier.
4. Choose regular supermarkets, which are relatively large. The plastic products in regular supermarkets are relatively reliable. The prices at farmers' markets and roadside shops are slightly lower, but the quality is not up to standard.
5. Look at the flexibility of plastic products. New material products have good toughness, are resistant to bending, will not deform, and will not break. The recycled material has poor toughness, is relatively brittle, and is easy to break.
Therefore, we should pay attention when purchasing plastic products in our daily life. First of all, we must understand the performance of the product and use the above methods to identify the quality of plastic products. Secondly, strictly follow the labeling of plastic products for strict implementation and use. Avoid chemical reactions during use that may cause harm to the human body.
