At present, photocatalyst is the fastest way to remove formaldehyde, many formaldehyde removal companies also use photocatalyst to treat formaldehyde, photocatalyst sprayed on the substrate, will form a protective layer, first seal formaldehyde, in the catalytic decomposition of formaldehyde, the photocatalyst itself does not participate in the reaction, only as a catalyst. However, after a long time of oxidation and wear, formaldehyde will leak, which requires frequent post-processing, and the previous photocatalyst can only work in the case of light, and now the photophyll catalyst will also work in the case of no light at night, but after several treatments, the indoor formaldehyde content will be controlled.

Anonymous users2024-01-23A photocatalyst is a catalyst that only occurs when exposed to light. It does not participate in chemical reactions and is very stable in nature, but under light, it converts light energy into chemical energy, excites the surrounding water and oxygen molecules to ionize, and releases hydroxyl radical intermediates with the highest oxidation potential, thus presenting a valuable photoelectric effect. Harmful gases can be oxidized and decomposed.
There are many types of photocatalysts, including titanium oxide (TiO2), zinc oxide (ZnO), tin oxide (SnO2), zirconium dioxide (ZrO2), cadmium sulfide (CdS) and other oxide sulfide semiconductors. In the field of indoor environmental protection, nano titanium dioxide (TiO2) is the most commonly used one, which has stable properties and good photocatalytic performance. Maya Blue Light Catalyst uses nano titanium dioxide (TiO2).
After the renovation of the house, there will be formaldehyde and other harmful substances, whether there is a peculiar smell is not the basis for judging whether it contains toxic gases and substances. Generally, a renovated house can only be inhabited after a month of ventilation. >>>More
1. Formaldehyde is removed by closed high temperature method, and the characteristic of formaldehyde is rapid release at high temperature. Specific operation: Close the doors and windows, turn on the air conditioner to raise the temperature to about 30 degrees, seal it for about a day, and then open the doors and windows for ventilation for a day. >>>More
Useful. However, photocatalyst film formation takes a certain amount of time (almost a week), during which light is required and ventilation is maintained. In order to prevent the film from being damaged, it is best not to live at home during this time, and do not clean, so as not to affect the effect, in addition to this, you can also choose materials such as photophyll so that you don't have to worry about these problems.
What to do if the photocatalyst formaldehyde remover sprays the furniture with white spots: the best way to use the photocatalyst formaldehyde remover should be sprayed on the wall rather than on the furniture, because the furniture is mostly made of wooden groups, and wooden products are easy to be eroded and deteriorated. Therefore, when spraying, it should be sprayed evenly, too close or too far will cause color changes or white spots, such as wooden furniture will change color, dark furniture, and even light color. >>>More
The best way to use photocatalyst formaldehyde remover should be sprayed on the wall rather than on furniture, because furniture is mostly composed of wood, and wooden products are easy to be eroded and deteriorated, and antique furniture is the same as solid wood furniture. Therefore, when spraying, it should be sprayed evenly, too close or too far will cause color changes or white spots, such as wooden furniture will change color, dark furniture, and even light color. The problem of white spots often occurs, so what should I do if white spots appear on the furniture sprayed with photocatalyst formaldehyde remover? >>>More
