Physical adsorption properties of activated carbon

A large number of molecules on the pore walls of the activated carbon can generate strong gravitational force, so as to attract impurities in the medium into the pores. It must be pointed out that the molecular diameter of these adsorbed impurities must be smaller than the pore size of the activated carbon, so that it is possible to ensure that the impurities are absorbed into the pores. That's why we create activated carbon with different pore sizes by constantly changing raw materials and activation conditions, making it suitable for a variety of impurity absorption applications.

Activated carbon is a very good adsorbent. It uses charcoal, bamboo charcoal, various shells and high-quality coal as raw materials to crush, sieving, catalyst activation, rinsing, drying and screening of raw materials through physical and chemical methods. It is manufactured by a series of processes. It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in the gas phase and liquid phase to achieve the purposes of decolorization and refining, disinfection and deodorization, and decontamination and purification. Product introduction: This series of activated carbon is made of high quality coal and refined with advanced process equipment. It has remarkable features such as low ash, high strength and high adsorption. Mainly used in water purification, air purification, protection, gas desulfurization and deodorization, solvent recovery and other fields.

1. Its own unique pore structure

Activated carbon is a kind of microcrystalline carbon material which is mainly made of carbonaceous material and has black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity. There are a large number of micropores invisible to the naked eye in the activated carbon material. The micropores in 1 gram of activated carbon material can be expanded to a surface area of ​​800-1500 square meters, and the special purpose is higher. That is, in a rice grain size activated carbon granule, the inner surface area of ​​the micropores may correspond to the size of a living room area. It is these highly developed pore structures such as human capillaries that give activated carbon excellent adsorption properties.

2, the interaction between molecules

Also called "Vandeva Gravity." Although the molecular motion speed is affected by temperature and material, it is always moving in the micro-environment. Because of the mutual attraction between the molecules, when a molecule is captured by the inner pores of the activated carbon into the pores of the activated carbon, more molecules are attracted because of the attraction between the molecules until the activated carbon is filled. The inner pores are up.

Physical adsorption occurs mainly in the process of removing impurities from the liquid phase and the gas phase by activated carbon. The porous structure of activated carbon provides a large amount of surface area, making it very easy to absorb and collect impurities. Like magnetic force, all molecules have mutual attraction

Stainless Steel Twill Dutch Weave Mesh, this kind of Woven Steel Mesh is weaved by a special weave technology, which integrate the Dutch weave and twill weave.  The thicker warp wire and the thinner weft staggered. Each warp wire shuttles up and down with the weft wire.
