? How to prevent indoor formaldehyde

Indoor formaldehyde will always be produced, and there is no way to completely eliminate formaldehyde in the air, but we can prevent it, and we can control formaldehyde within a reasonable concentration range. Let me talk to you about the prevention and treatment methods of indoor formaldehyde, hoping to help you.

Prevention and control methods of indoor formaldehyde

A, ventilation method

The most traditional indoor air purification method is best used in the early stage after decoration. Most families need ventilation. Whether the house is polluted by air or not, it is always beneficial and harmless to ventilate the room, and this method is completely effortless, just open the window. However, as the original air purification method, ventilation method also has great shortcomings. In the case of southerly wind, ventilation by opening windows will definitely cause indoor humidity and bring more trouble. In addition, this method takes a long time, especially for newly renovated houses, which need to be aired for several months to achieve significant purification effect, which is time-consuming and unbearable for users who urgently need to stay.

Second, the plant planting method

Plant planting is also a primitive method, which can add vitality to the home, can be used for a long time, and has no secondary pollution. According to scientific research, some plants can absorb harmful gases and purify air quality, and plants themselves can absorb carbon dioxide to make air and water, which has certain ornamental value. However, the effect of plant planting method is not obvious, and only some harmful substances can be adsorbed. If indoor pollution is serious, plants may also be poisoned and die. Therefore, the plant planting method is only ornamental.

Third, activated carbon adsorption method

Activated carbon can adsorb all kinds of harmful substances, which belongs to pure physical adsorption and has no secondary pollution. It is widely used in daily disinfection, antivirus and other daily necessities, and the use effect is good, often lasting for 3~6 months. The use of activated carbon is very simple, as long as it is directly placed in drawers and cabinets, which will not affect the normal use of furniture. However, activated carbon also has a saturation period. When saturated, it will lose its activity and need to be replaced frequently. In addition, activated carbon is not omnipotent, which is especially unfavorable when dealing with adsorption in large spaces such as houses. A large number of activated carbon placed at home, but also hindered the indoor beauty, the same position.

Fourth, the air purifier

Air purifier is a relatively scientific purification technology, which can purify all kinds of harmful substances without causing secondary pollution. Nowadays, with the increasing consumption level, it has been favored by people. However, it does not mean that the air purifier is pollution-free, but the purifier has only been treated to a certain extent. Different products have different effects, and the price of the purifier with good purification effect will be relatively high, and the service life of different products will be different.

V. Purification method of photocatalyst

Photocatalyst is an advanced indoor decontamination technology, which can be said to be the longest in all purification methods, and there is no secondary pollution. Photocatalyst has the functions of sterilization, deodorization, anti-pollution, hydrophilicity and anti-ultraviolet. Its effect is thorough, safe, efficient and lasting. It is suitable for indoor and automobile air purification and is known as "the most ideal new sterilization and purification technology". However, this kind of products are mixed in the market, and the effect of inferior products is poor. Photocatalyst construction needs professionals, so you must choose a good brand when buying. Jilin Titanium Hu Ba Purification Technology Co., Ltd. adopts polymer nano-active titanium Hu Ba technology. Under the irradiation of ultraviolet rays or sunlight, the electrons on the catalyst surface absorb enough energy to be excited, and a positively charged hole is formed at the position where the electrons are excited. This hole will release nearby water molecules from hydroxyl groups (OH-) and oxidize them (that is, capture their electrons), making them active ions. Once they encounter organic substances, they will take back electrons and organic molecules will be combined. In fact, polymer nano-active titanium is a kind of semiconductor material "titanium dioxide" (TiO2), which can form nanoparticles or liquids. After being irradiated by ultraviolet light (rapid reaction) or ordinary visible light, it can produce highly oxidized active ions on its surface, which can decompose some harmful substances in our living space.
