Why can the net aldehyde antibacterial core board of Oupai wardrobe be mildew-proof? Is it true or not?

It's true. As far as I know, it is because their pure aldehyde antibacterial core board has a patent on nano-silicon black technology. This substance contains negative charge of 1.8 million units, which can pierce the cell wall of bacteria at high speed and inhibit the growth of six common easy-to-grow molds. However, this "anti-mildew" effect is the result of testing specific strains under specific experimental conditions. In different environments, the mildewproof effect may be different, but generally speaking, it is mildewproof in rainy days.
