The environment of our lives is constantly being destroyed by us, and it has also led to many problems in our lives. The lack of water resources and the damage of the soil. The development of green products must be developed to take the road without pollution, easy decomposition, and recyclable in order to get the choice of direct users and indirect users. In order to properly solve the problem of protective membrane garbage, chemists are now changing the structure of the protective film, so that the abandoned protective membrane can be completely decomposed in less than a long time.
At present, there are two types of plastics such as decomposed protective films. One type is the type of light decomposition. During the manufacturing process, this type of plastic is added with a light -sensitive group every certain distance on its polymer chain. Such plastic is safe and stable under the irradiation of artificial light, but under the irradiation of sunlight, the light sensitivity group can absorb sufficient energy and break the high molecular chain to break here, so that the plastic can be decomposed. Another type is biological decomposition plastic. This type of decomposed plastic is introduced on the polymer chain to introduce some groups so that the microorganisms in air and soil can break the high molecular chain into fragments and then completely decompose it.
In order to reduce unnecessary waste and improve the advantages of our products in appearance, what are the requirements for choosing a protective film 1. Appropriate viscosity: easy to paste and tear; The smaller the increase, the better; 3. Good weather tolerance: Under the conditions of sunlight, the use period is as long as half a year to one year; 4. The storage period is long: Non -corrosion: The adhesive is inert, and it will not have a chemical reaction with the surface of the adhesive material; 6. Excellent mechanical properties: the anti -tension strength, elastic modulus, and extension rate of the user requirement.
