Problems solved by technology

However, in actual production, it was found that the nano-titanium dioxide solution sol was added to the coating system and then flocculated into a large particle size and precipitated. When the nano-titanium dioxide particles were flocculated, the photocatalytic performance of the nano-titanium dioxide coating was greatly reduced.
In addition, due to the quality of the process of preparing wall paint, although the wall paint sold on the market has a good effect of absorbing and decomposing pollutants, it also has the disadvantages of being easy to absorb dust and difficult to clean.
