What Are The Effects Of Activated Carbon? How Long Is The Duration Of The Use Of Activated Carbon?




Activated charcoal is made up of charcoal, many kinds of shell and high quality coal, and then it is made by some physical methods, such as crushing, screening, activating catalyst, rinsing, drying and screening. Then, what are the functions of activated carbon? How long will the activated carbon use?

Activated carbon


1. At the very beginning, activated carbon was used to make gas masks. With the development of society, activated carbon was used for deodorization in water works. Now, activated carbon is not only used to produce gas mask and water plant deodorization, but also used for decolorization of sugar, cigarette filter, air purifier, sobering, pollution of radiation, reducing pesticide residues in soil, regulating soil properties, controlling indoor formaldehyde, fresh vegetables, and so on. The application is very wide.

2, it is well known that activated carbon is a kind of carbon material made of carbon containing material with black appearance, developed internal pore structure and strong adsorption capacity. And there are many micropores that we can't see with our naked eyes. These invisible micropores have very strong uses. Therefore, activated carbon has a good adsorption capacity.

3, activated charcoal is also called "van der Waal gravitation". As we all know, the motion speed of molecules will be affected by temperature and material, but activated carbon molecules are constantly moving in the micro environment. This is because of the interaction between the active carbon molecules, when a molecule is caught in the pores in the activated carbon by the inner pores of the activated carbon, and the attraction of the molecules to each other causes more molecules to be continuously attracted until the pores are filled with activated charcoal.

4. According to the material

Nowadays, there are many kinds of activated carbon on the market. They are different in material selection, so the pore size is large and different. In general, the quality of high quality coconut shell activated carbon adsorbing harmful substances can be close to or even achieve its own quality. Activated charcoal is a physical adsorption principle, which is defined as a passive air purification material in the process of action.

Time limit for activated carbon

The useful life of activated carbon is affected by the total amount of harmful substances and the frequency of desorption. The quality of the harmful gas adsorbed by activated carbon can be close to the quality of its own. In the ordinary household air, the quality of the harmful gas is far less than the use of activated carbon. Therefore, it can be used for a long time as long as the activated carbon is often placed in the sun.
