According to the performance of the gas mask, pore size distribution must be in the majority with microporous activated carbon, such ability are more suitable for the diameter smaller molecules adsorbed substance (toxic gases), activated carbon adsorption holes sluice or hole width if less than the adsorbate molecule critical diameter, hole is invalid, but too wide pore and can only play the role of diffusion channel.
Therefore, only the critical molecular diameter of the adsorption is smaller than the hole width and can not exceed a certain size requirement (according to the different types of antivirus).
 
The activated carbon agent in the gas mask wants to know what an active carbon agent is, and the first thing is to figure out what is activated carbon.
Activated carbon is a granular porous crystal or powder, often black.
A porous structure is a carbon that has an excellent adsorption capacity for gases.
According to the different materials, the activated carbon is usually divided into two types: wood coal.
Gas masks in the filter cartridge, mostly woodiness active carbon, give priority to with granular shape, according to the performance of the gas mask, pore size distribution must be in the majority with microporous activated carbon, such ability is more suitable for adsorption of molecular diameter smaller substances (toxic gases), activated carbon adsorption holes sluice or hole width if less than the adsorbate molecule critical diameter, hole is invalid, but too wide pore and can only play the role of diffusion channel.
Therefore, only the critical molecular diameter of the adsorption is smaller than the hole width and can not exceed a certain size requirement (according to the different types of antivirus).
Gas mask the maximum efficacy lies in its ability to all sorts of toxic gas decomposition, can also be shown as is associated with some kind of adsorption material has been break down, and to achieve such effect, then must demand gas mask used by activated carbon is up to the related standard.
