The function and application characteristics of activated carbon

First, the application of activated carbon

1, new housing: used to absorb the indoor air quality of the new house and continue to release into the air decoration formaldehyde, volatile phenol, nitrogen dioxide and radon and other harmful substances, quickly remove furniture odor.

2, furniture: used to absorb furniture continued to release decoration formaldehyde, volatile phenol, and a variety of odors.

3, wardrobe, bookcase, shoe cabinet: to remove odor, silt, moisture, insect prevention, odor, sterilization, storage, etc.

4, bathroom: deodorizing sterilization, fresh gas.

5, wooden floor: to odor, moisture, odor, moth-proof, maintenance and maintenance of wooden floor is not deformed.

6, cars: absorb all kinds of harmful substances in the new car and all kinds of odors in the older car.

7, computers,home appliances,adsorption,reduce the damage of radioactive substances to people.

8, corporate offices, hotel rooms and other public places: purify indoor gas, eliminate odor.

Second, the role and efficacy of activated carbon

Activated carbon is also called active carbon black. It is amorphous carbon in the form of black gray powder or particulate matter. Let's take a look at the role of activated carbon. Activated carbon has a significant "physical adsorption" and "analytical chemical adsorption" effect, which can adsorb some analytical chemical compounds to ensure the removal of the desired effect. Activated carbon is now widely used to clean the air in cars and homes. Activated carbon is a kind of porous material carbon content material, its more prosperous void structure makes it has a very large total area, so it is easy to touch the harmful substances in the air, the strong adsorption force field near the activated carbon hole will immediately inhale the harmful substances molecular formula into the hole, so the activated carbon has a strong adsorption professional ability.

Third, the characteristics and process of activated carbon adsorption

The great feature of activated carbon adsorption is that the color rate is faster, the adsorption work is hard, and the pigment in the potion can be effectively adsorbed, and the sediment of the potion can be reduced, without affecting the concentration value of other components of the potion and the medicine.

When purchasing, please remember that the smaller the particle, the better the effect. Because the greater its total surface area, the more pores it has. However, the particles should not be too fine into powder, so as not to cause inconvenience in use and affect the filtration flow of the filter. Generally, a particle size of about 1MM in diameter is preferable.

Physical adsorption, also known as van der Waals adsorption, is caused by the electrostatic force or van der Waals attraction between the adsorbent and the adsorbent molecules. When the molecular attraction between the solid and the gas is greater than the attraction between the gas molecules, the gas molecules will condense on the solid surface even if the pressure of the gas is lower than the corresponding operating temperature and saturation vapor pressure.
