Problems solved by technology

[0005] Children's wooden products such as children's tables, chairs, baby carriages, children's wooden toys, building blocks, pencils and other daily necessities, even if children's toys are made of water-based paint, it is not yet environmentally safe
Because it is easy to produce mold, bacteria and air pollution during the use and storage of toys, which is directly harmful to children
At present, antibacterial materials (antibacterial coatings, antibacterial plastics, antibacterial stainless steel, antibacterial paper, etc.) have appeared, but people's research on antibacterial coatings is mainly to realize the sterilization function through bactericides, which are mainly used for indoor walls, toilets, floor coatings, etc. However, for children's toys that children are in close contact with, the use of fungicides is not conducive to the health of children.
