How is the effect of photocatalyst?
- 2018-11-12 -

After so many introductions to the photocatalyst by Xiaobian, I believe that everyone knows a little about it. So, do you know the effect of photocatalyst?


First, completely safe, no secondary pollution. Because the photocatalyst has an advanced principle of action, it can form a film on the surface of the decoration materials and furniture. Before formaldehyde and other air contact the human body, it quickly decomposes and removes indoor pollutants such as formaldehyde, benzene, ammonia, TVOC, carbon dioxide and water. Harmful treatment, no secondary pollution, let people use peace of mind.

Second, a spray, more effective for a long time. In theory, if the photocatalyst is not worn, because it only acts as a catalytic platform, it does not react itself, does not wear out, and can be sprayed for a long time.

Third, the photocatalyst can increase the indoor air negative ion concentration. The 100 square meter house is sprayed with photocatalyst, which is equivalent to the amount of negative ions released by 10 birch trees at the same time, so that the homeowner can be born with natural, big seaside and big forest. feel.

In theory, photocatalyst is a kind of high-quality formaldehyde-removing product. In fact, photocatalyst should play a role, it must be stimulated by ultraviolet light, and ultraviolet light can not always exist in the room, especially in some drawers, the back of the cabinet and other formaldehyde release. In a serious place, you can't see the light. This limits the role of the photocatalyst. Secondly, different kinds of photocatalyst effects are different. Even if it is the same kind of photocatalyst, the particle size determines the actual effect. Generally speaking, the smaller the particle, the better the effect. There are countless photocatalyst products on the market. Often, some unscrupulous merchants shoddy and manufacture photocatalyst products with inferior titanium dioxide with a particle diameter larger than 100 nanometers. Such products have virtually no effect. The quality of the photocatalyst should be within 10 nanometers.

In addition, the photocatalyst can produce oxidative properties when it is visible, but only when the harmful gas and the photocatalyst encounter light, it will be oxidized and decomposed, which limits the effect of the photocatalyst. Some adsorbent materials themselves also contain photocatalyst components, which have a better removal effect on harmful gases.
