First, Ruishi
It is a very popular purification product in the market in recent years, mainly because it has dual functions of absorption and decomposition, and can actively absorb free formaldehyde in the air without worrying about the influence of external factors such as temperature, humidity and light. The absorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body without air drying and secondary pollution. It should be noted that it is an irregular gray ore, not a round particle.
Second, the fan
As we all know, the easiest way in in addition to formaldehyde is ventilation. Families with poor room ventilation can speed up indoor and outdoor air flow and exhaust formaldehyde-containing air through fans, which can effectively reduce indoor pollutant concentration, but it can only treat the symptoms, not the root cause, and this method may not be practical in the season when it is necessary to keep warm.
Three. activated carbon
Using activated carbon is also a good choice. The surface of activated carbon is rich in pores, which can absorb indoor odor and play a certain role in pollution control. However, the treatment capacity of activated carbon is limited, and it will be saturated after about half a month of use, so it can't continue to work. In order to achieve the purpose of treatment, it is necessary to constantly replace new carbon packs, which invisibly increases the treatment expenditure?
Fourthly, optical contact medium.
At present, most of the photocatalysts mentioned by people are titanium dioxide, which can decompose formaldehyde into carbon dioxide and water by ultraviolet irradiation. However, the work requires the participation of light and ultraviolet rays, which has certain limitations in in addition to formaldehyde.
Verb (abbreviation for verb) high temperature
The release speed of formaldehyde mainly depends on two factors, one is temperature and the other is humidity, so we can make use of this characteristic of formaldehyde and use heaters and humidifiers. To keep the room in a high temperature and humidity state, then we can cooperate with ventilation or adsorption materials to absorb formaldehyde that has been released at home. This method is mainly to control formaldehyde lurking at home, and the effect is very good.
Formaldehyde is a high-grade toxic substance and a potential carcinogen. Before moving into a new house, in addition to formaldehyde is the top priority. According to the above, you can choose a variety of methods at the same time.
