(1) Activated carbon:
   Activated carbon is a black powder, granules or pellets having a porous amorphous carbon mainly composed of carbon, also contain small amounts of oxygen, hydrogen, sulfur, nitrogen, chlorine. Also it has a fine structure as graphite, but the smaller grains, irregularly stacked between layers.
   It has a larger surface area (500 to 1,000 m 2 / g), there is a strong adsorption properties, can absorb a gas, liquid or colloidal solid on its surface; for liquid, gas adsorbing substance quality may close the quality of the activated carbon itself. Which is selective adsorption, non-polar material is more easily adsorbed than the polar substances. In the same series material, higher boiling materials are more easily adsorbed, the lower the temperature the greater the pressure the greater the concentration, the greater the amount of adsorption. On the contrary, under reduced pressure, temperature favor desorption gas.
   Commonly used in gas adsorption, separation and purification, solvent recovery, sugar, oil, glycerol, drug bleaching agent, water and refrigerator deodorant, gas mask canisters agent, also used as a catalyst or a metal salt supported catalyst. Early production of activated carbon materials as wood, hard fruit shell or animal bones, and later mainly coal, dry distillation, after activation get activated carbon production methods are:
① steam, gas activation method. By steam or carbon dioxide at 850 ~ 900 ℃ activated carbon.
② chemical activation. The use of gas released activator, or activator impregnated materials in high temperature treatment can be obtained activated carbon.
   The industrial application of activated carbon also requires mechanical strength, wear resistance, and it sought to stabilize the structure, adsorption energy required is small, in order to facilitate regeneration. Activated carbon for oil, beverages, food, drinking water, bleaching, deodorization, gas separation, solvent recovery and air conditioning, as an adsorbent and catalyst carrier gas masks.
(2) Air filter:
   Acronym filter masks works containing harmful substances in the air before being inhaled through the evolution of the media filter masks.
   Filter masks is our daily work of a large class of the most widely used, the following detailed description of such a mask selection method and conditions of use. A filter mask structure should be divided into two parts, one body mask, we can simply be understood as it is a mask shelf; the other is the filter portion comprises a filter for dust and cotton with antivirus chemical filtration boxes.
   Therefore, the choice to use filtering respirators, the production of some products to your home wide provides the following convenience, that is, you can use the same kind of mask body, when the dust-exposed environment requires dust, coupled with the corresponding cotton filters, so that you wear a dust mask; when the need for anti-virus in a toxic environment, cotton filters replaced, mounted with the corresponding chemical filter cartridge, so it became a respirator, or Depending on your operational needs, to provide you with more combinations.
