Children's toys or supplies made of antibacterial plastics can effectively prevent the growth of germs and are healthier for children; plastic raw materials made of coconut shells can be fully degraded, pollution-free and more environmentally friendly ... Yesterday morning, the fifteenth The China Plastics Fair opened in Yuyao. With the increasing application of plastic products, energy saving and environmental protection have become the development trend.
Adding antibacterial agent plastic can also be antibacterial
Children's plastic toys have been playing for a long time, and parents always think about how to sterilize. If antibacterial plastic materials are used, parents will be more at ease. At the Plastics Expo, Sinopec (600028, Share it) Beijing Institute of Chemical Technology displayed baby carriages, toys, etc. made of antibacterial plastics. In order to increase the credibility of customers, an antibacterial test report was also displayed.
"This is a new achievement we developed last year. After testing, the antibacterial rate of antibacterial plastics against Escherichia coli and Staphylococcus aureus reached 99%, and the price was only about 5% higher than ordinary plastics." The staff introduced So it can be antibacterial, because it has added nano-scale nano-composite antibacterial agents, which can be applied to almost all plastic materials, just like MSG, making ordinary plastics become "antibacterial plastics", antibacterial plastics can be used For the production of toys, tableware, household items, etc., it is currently used in washing machine interiors and strollers.
Coconut shell made of plastic can be fully degraded
This year, about 80% of energy-saving and environmentally friendly products were held at the Plastic Expo. A German company introduced a plastic made of coconut shell. The biggest feature is that it is degradable and more environmentally friendly. "This kind of plastic is made of coconut shell or hemp, and it can be made into some bowls, dolls, etc. Even if the child eats the toy in his mouth, he does not have to worry about the harm." The staff introduced, this plastic made of coconut The disadvantage is that it is relatively brittle and can only be made as apparent parts, not as structural parts.
Many degradable disposable tableware is really not completely degraded because of the material relationship. At the Plastics Fair yesterday, the Ningbo Institute of Materials Research of the Chinese Academy of Sciences showed a heat-resistant polylactic acid meal box. The main materials are corn starch and lactic acid. The meal box can be completely degraded in a natural environment for a few months, and it really does not stay. Traces, and can withstand high temperatures of 120 degrees Celsius. The staff introduced that this kind of meal box is more expensive than ordinary, and it is very popular in Europe and the United States, and has market prospects in China.
