What's the indoor environment like in Wuhan, in addition to formaldehyde?

Its biggest advantage is that it absorbs a large amount of formaldehyde first, and then completely decomposes formaldehyde into harmless substances, which will not be saturated, and has a validity period of more than three years and does not need to be replaced all the time. It can purify formaldehyde for a long time and has the best ventilation effect. On the one hand, ventilation can reduce the concentration, on the other hand, it can absorb and decompose formaldehyde for a long time, which is super simple to use and very suitable for families with heavy pollution or urgent occupancy.

2. Green plants

As we all know, plants make high-quality air in nature. The problem of high formaldehyde content can be well solved by raising plants such as green radish, tiger tail orchid and chlorophytum at home.

3, to aldehyde spray

Nowadays, the popular spray does not directly remove formaldehyde, but a chemical substance that interferes with formaldehyde volatilization and eliminates formaldehyde. But it needs to be used frequently to ensure the effect. However, if used frequently, kitchen utensils or tableware at home will leave a lot of chemical residues, which will have an impact on the human body.

Extended data:

It is reducible, especially in alkaline solution. Can burn, steam and air form an explosive mixture, the explosion limit is 7%-73% (volume), and the ignition point is about 300℃. It can be prepared by dehydrogenation or oxidation of methanol under the catalysis of metals such as silver and copper, and can also be separated from oxidation products of hydrocarbons.

It can be used as raw materials for phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pentaerythritol, dyes, pesticides and disinfectants. Industrial formaldehyde solution generally contains 37% formaldehyde and 15% polymerization inhibitor methanol, and its boiling point is 10 1℃. Formaldehyde itself can undergo condensation reaction. Add 10%- 12% methanol as polymerization inhibitor in general commodities, otherwise polymerization will occur.

It can perform aldol condensation reaction with aldehydes and ketones. It is easy to condense with ammonia or amine compounds, for example, it reacts with ammonia to produce urotropine, and condenses with urea to produce dimethylol urea. Ethylene glycol can be produced by condensation of formaldehyde with synthesis gas.
