An activated carbon adsorption capacity and its shape is a great relationship. The smaller the particles, the larger the surface area, the better the adsorption. Conversely, a lump of activated carbon adsorption worst. Therefore, if the use of bulk carbon, preferably spread into a plane. (2) on the use of activated carbon purifier in a long time, get the sun dry in the sun you can continue to use. 3 In addition to the bookcase and drawers outside, activated on bamboo baskets, or spend a cupboard where heating cover will be more convenient. 4 families with high floor for activated carbon, can extend the life of the floor. Comments: activated carbon products are the world's most effective air purification one of the means used during the period of the First World War gas mask, is an internationally recognized drug experts, from last year's "SARS", the activated carbon masks that many people remember . If the size of 0.42 ~ 0.85mm granular activated carbon as the main component of the carrier do, because the country's two on indoor air quality standard GB50325 and GB/T18883 has been clearly defined for adsorption indoor harmful gas is 20 to 40 mesh activated carbon. "Carbon itself water and air purification effect on the present two main sources of air pollution formaldehyde and benzene adsorption effect is very good. And after the renovation period, the main role of activated carbon in order to adjust the air humidity will change." Song Guangsheng introduced, activated carbon can absorb moisture from the air, and thus play a role in regulating the air humidity. In addition, if the home shop is solid wood flooring, below a layer of activated carbon will extend the life of wood flooring. Activated carbon can absorb moisture from the air to ensure a constant humidity of the floor. In the climate is dry, the moisture will be activated gradually released. Comments: Activated carbon structure is characterized by pores, and thus there is a strong adsorption, dehumidification, mold, plus charcoal itself has medicinal sterilization debugging functions (According to "Compendium of Materia Medica" records), so make precious qualities of ancient painting and calligraphy has always maintained, safe and sound. In addition, the home medicine box placed a packet of activated carbon, can also play a moisture-proof, anti-high temperature effect, effectively saving drugs to non-perishable.
