First, Ruishi
It can actively adsorb indoor free formaldehyde, and the process will not be affected by any external factors such as temperature, humidity and illumination. The adsorption rate of formaldehyde is also dozens of times that of ordinary adsorption materials. In addition, its unique decomposition function can decompose the adsorbed formaldehyde into harmless carbon dioxide and water, and then discharge it, so that its internal pores are always in an unsaturated state, and the formaldehyde removal rate can reach over 90%. It should be noted that it is an irregular gray ore, not a round particle.
Second, open the window for ventilation.
Window ventilation is a very simple method to remove formaldehyde. The purification principle is indoor and outdoor air circulation replacement, which can release harmful gases such as free formaldehyde in indoor air to the outside and reduce indoor formaldehyde concentration. Its aldehyde removal efficiency is directly related to outdoor wind power. Generally, the greater the outdoor wind, the higher the purification efficiency?
Three. activated carbon
There are a lot of irregular pores in activated carbon, among which pores similar to formaldehyde molecules will adsorb formaldehyde, which can achieve the purpose of purifying the air. However, the number of internal pores is limited, which may cause secondary pollution when saturated, and must be replaced regularly when used.
Four, formaldehyde scavenger
There are many principles of formaldehyde scavenger, including decomposing formaldehyde and blocking formaldehyde. The former only decomposes free formaldehyde, and the bound formaldehyde in the material is still being decomposed and released. The latter uses a protective film to isolate formaldehyde from the air, and formaldehyde still exists. When the protective film is broken, formaldehyde will still gush out in large quantities!
Verb (abbreviation for verb) high temperature
As we all know, formaldehyde is volatile at high temperature. We can use some heating equipment to raise the temperature at home a lot, let a lot of formaldehyde gas evaporate, and then we can achieve the goal of in addition to formaldehyde by opening the window for ventilation. After repeated operations, most of the formaldehyde in the house can be removed, but you must pay attention to safety when using heating equipment to avoid fire.
Formaldehyde has been ranked second in the priority control list of toxic chemicals in China, which shows how toxic formaldehyde is. Therefore, the first step after the renovation of the new home is in addition to formaldehyde, and the efficient method is to carry out several methods at the same time.
