Biqing water free samples, technical support after-sales tracking, your satisfaction, my pleasure ......... coconut shell activated carbon is a porous material containing carbon, it has a highly developed pore structure, is a very good adsorbent, activated carbon adsorption per gram more equivalent to a large area of ??eight tennis courts, while its adsorption is constituted by physical adsorption and chemical adsorption. Its composition of the material in addition to carbon elements, still contains a small amount of hydrogen, nitrogen, oxygen and ash, six-ring structure of the carbon material piled formed. The six ring carbon irregular arrangement, resulting in a microporous activated carbon characteristics volume and high surface area. Activated carbon is widely used in domestic water and food industry, chemical industry, electric power and other industrial, domestic water. Due to the large surface area of ??the activated carbon, its surface and covered with an average diameter of 20 to 30 Angstroms (A) pore, therefore, the activated carbon has a high adsorption capacity. In addition a large number of activated carbon surface hydroxyl and carboxyl functional groups on various properties of organic materials into the wash chemical adsorption, and electrostatic attraction effect. Activated carbon adsorption is due to the use of activated carbon surface molecules with a surface discontinuity balanced and remaining energy. When a collision to a solid surface material, are attracted and stay in the activated carbon surface, so as to achieve bleaching, to smell, to remove heavy metals, all kinds of dissolved organic matter, and other radioactive elements. Removal of harmful substances. Purification of the activated carbon filter, iodine value in 1200 after more than pickling, 10-24 mesh particle diameter. It can effectively adsorb residual chlorine. Activated carbon can be made from many kinds of carbon-containing substances, these materials include wood, sawdust, coal, coke, peat, lignin, stone, hard shell, sugar pulp, bone, lignite, petroleum residue and so on. Including coal and coconut shell activated carbon manufacturing has become the most commonly used raw Youdou. The manufacture of activated carbon is basically divided into two processes, the first process including dehydration and carbonization, the raw material is heated at a temperature of 170 至 600 ℃ drying, the original organic matter about 80% charring. The second process is to make the charcoal activated, which is through the use of activators such as water vapor and carbon to complete the reaction, the endothermic reaction is mainly in the mixed gas consisting of CO and H2, for burning charcoals heated to a suitable temperature (800 to 1000 ℃), to burn them all biodegradable material, the resulting well-developed porous structure and huge specific surface area, which has a strong adsorption capacity.
