Mesh activated carbon, refers to the particle size or thickness of the material. General definition refers to the screen in one inch * 1 inch of the area within the material through the sieve, sieve the number of holes is defined as the mesh. Such as 200 mesh coal activated carbon decolorization rate, that is the material can have a 200 mesh sieve within 1 inch by 1 inch. And so on, for the activated carbon, the mesh size greater, indicating finer granularity shell activated carbon; the smaller the mesh, indicating that the larger the size of activated carbon. Song Xin wood powdered activated carbon manufacturers to produce various heads of granular activated carbon is generally more than 100 projects, powdered activated carbon particles will tend to the activated carbon adsorption values, but it is still smaller particles mesh, then the larger particles of activated carbon, such as 8 mesh -12 mesh activated carbon particles are great. In general, the activated carbon per unit volume in the mesh, the more the area of ??maximum contact with the air, the better the adsorption. This is a limited shell activated carbon filter, such as charcoal. Large hole, small mesh, a small contact area. Coconut shell activated carbon, mesh and more contact area of ??activated carbon, the effect is good. Refined coal into charcoal for industrial use only, home on a free. Take the same 10-24 5-10 mesh and charcoal water purification purposes, the same under the weight of activated carbon 10-24 purpose contact area, good purification effect, but his slow flow, water less, if installed in the net water equipment, small devices with small particles, large equipment with large particles. Tell coconut shell activated carbon coconut shell activated carbon, those methods have much higher costs than coal activated carbon, activated carbon materials and finished products are generally less likely to be recognized by the general public. Often unscrupulous sellers on the market does not recognize the use of consumer material weaknesses, activated carbon from coal sales of fake coconut shell charcoal, whether civil or industrial use in the field, this phenomenon is more serious. How do we distinguish genuine coconut shell activated carbon it? First, everyone concluded the following four points: the first point: Nutshell activated carbon coconut shell activated carbon belongs to the category, and its main feature is the density of small, light touch in his hand weight was significantly lighter than the activated carbon from coal. The same weight of activated carbon, coconut shell activated carbon is generally greater than the volume of activated carbon from coal. The second point: the shape is generally broken coconut shell activated carbon granules, flakes, and molding activated carbon, such as cylindrical, spherical activated carbon, mostly from coal char. The third point: because of the density of small coconut shell activated carbon, feel lighter, so it can be activated into the water, coal carbon sink to the bottom faster in general, and coconut shell activated carbon floating in the water longer, with the active saturated carbon adsorbed water molecules, adding its own weight will gradually sink to the bottom of all, when activated all sink to the bottom, you'll see outside are activated every single bubble wrapped with a small, crystal Ti thoroughly, very interesting. Fourth: coconut shell activated carbon pore structure of small molecules, the activated carbon into the water, when it absorbed water molecules will produce many rows of very small air bubble (just the naked eye can see), dense kept floating to water. The coal quality is generally activated carbon pore structure of macromolecules, bubble phase also produced larger. From the four points above them, we can distinguish good genuine coconut shell activated carbon, so we would not have to buy counterfeit products, and consumers have a protective effect, so that customers are assured.
