What is activated carbon?
Sex charcoal is also called activated carbon black. It is black powder or granular amorphous carbon. The main components of activated carbon are oxygen, hydrogen and other elements except carbon. Activated carbon is a kind of porous carbon with low bulk density and large specific surface area, because microcrystalline carbon is irregularly arranged in structure and there are pores between cross connections, which will produce carbon tissue defects when activated. Activated carbon is odorless, tasteless, sand-free, insoluble in any solvent, has selective adsorption capacity for various gases, and has high capacity adsorption capacity for organic pigments and nitrogen-containing alkali. The total surface area per gram can reach 500 ~ 1000m2. The relative density is about 1.9 ~ 2. 1, and the apparent relative density is about 0.08 ~ 0.45.
How to use activated carbon
In fact, the use of activated carbon is very simple. Open the outer package of activated carbon, take out the small charcoal bag and put it directly near the pollution source, such as drawers, nightstands, wardrobes, bookcases, sofas, beds and other relatively unventilated corners near the pollution source. Put activated carbon without closing doors and windows, and the ventilation effect is better. Don't worry about dust when opening the window. Which is more important, hygiene or human health?
Activated carbon needs to be taken outdoors to dry after being used for a period of time. The purpose of drying is to release the internal space of activated carbon occupied by water through the exposure of the sun, so as to better absorb harmful gases. It is recommended to sunbathe for 3-5 hours every 20 days or so.
