 Nutshell Activated Carbon it has a very strong adsorption ability, it is widely used for air purification, anti-virus protection, water, solvents, bleaching and other industrial and civil fields. In recent years, as people gradually realize that the activated carbon, activated carbon market, rapid development, but at the same time in the development of the poor quality of activated carbon products also stepped in, and seriously affected the normal development of the activated carbon market to consumers caused adverse consequences. In order to allow consumers to choose to rest assured that the products here on how to choose high quality activated carbon to make a brief description. Activated carbon although in appearance and use, there are many varieties, but activated carbon has a common characteristic, that is, the adsorption. Activated carbon to produce the adsorption of the reasons is because it has a well-developed pore structure, as we have seen a sponge, under the conditions of the same weight, the sponge can absorb more water than any other object, the reason is also because it has developed pore structure. But the pore structure of activated carbon to the naked eye can not see, because they have only 1 × 10-12mm-10-5mm between, not much bigger than a molecule. Developed the extent of activated carbon pore is difficult to imagine, take 1 gram of activated carbon, to which all the pore wall and launched into a plane, this area will reach 1000 square meters (both specific surface area for 1000g/m2) The main factor of activated carbon adsorption depends on the level of development of the internal pore structure. In the production process, the only way to improve the performance of activated carbon adsorption is to control the production process, the pore structure of activated carbon per unit volume to increase as much as possible. Therefore, the higher the adsorption properties of activated carbon due to contain a large number of pores, makes its own density to become smaller, which is why activated carbon adsorption of the better feel the more light the reason (the premise is to use the same raw material production, does not dip over the water or adsorption of other substances). The same time as the higher cost of production of activated carbon adsorption improve, but it is growing exponentially, which is useful for low adsorption on activated carbon in the market posing as the motive of the activated carbon sales. Uniform standards, so that production can be controlled based calibration of activated carbon adsorption, the higher the adsorption value of iodine adsorption, or adsorption value of carbon tetrachloride (CTC), commonly used in the activated carbon industry, the stronger the adsorption capacity of activated carbon. Understand the above points, it is not difficult to judge the quality of activated carbon performance. The higher the adsorption values ??of activated carbon the better the performance. How easy it is in the testing equipment to identify the level of activated carbon adsorption values? Here are several easy methods for reference. 1, a direct look at the indicators provided by the manufacturer. Commonly used activated carbon adsorption indicators are: iodine value, carbon tetrachloride (CTC) adsorption value and methylene blue adsorption value, iodine adsorption value used to represent the adsorption capacity of activated carbon for liquid substances, carbon tetrachloride adsorption value used to represent activated carbon adsorption capacity for gaseous substances, methylene blue adsorption value is used to indicate the active carbon capacity. The higher the three indicators it has a very strong adsorption ability, it is widely used for air purification, anti-virus protection, water, solvents, bleaching and other industrial and civil fields.
