Problems solved by technology

Although existing inorganic metal antibacterial coatings have antibacterial properties, such as using nano-silver as a bactericidal component, the antibacterial time is short, prone to oxidation and loss, and is easy to be stained with dust, easy to absorb water and deteriorate, low in hardness, easy to damage, easy to fall off, and Environmental performance is poor
Traditional fungicides usually contain toxic substances, and formaldehyde, a carcinogen, will be produced after coating
