Supply the food industry with high decolorizing charcoal decolorizing charcoal factory sales

Decolorizing charcoal Profile: decolorizing charcoal is high quality wood as raw material, the use of zinc chloride production, has developed in the pore structure, high adsorption capacity, fast filtering features. Mainly applicable to a variety of amino acid industry bleaching, refined sugar bleaching, MSG industry, glucose industry, starch sugar industry, chemical additives, dyes intermediates, food additives, drugs of high pigment solution, purification, odor, purify. Production of phosphoric acid decolorizing charcoal, has developed in the pore structure and developed specific surface area, adsorption capacity, filtering speed, characteristic of free zinc. Activated carbon bleaching process technology: This series of products use wood, charcoal and other materials as raw materials, the use of chemical or physical methods produce two activation process, powdered activated carbon treated impurity and scientific formula refined. Decolorizing charcoal features: a large surface area, developed micro-crystals, effective pore structure, adsorption capacity, filtration speed and other characteristics. Decolorizing charcoal adapt Uses: Widely used in liquid phase adsorption, gas adsorption, mainly used in the field of chemical industry, dye industry, pharmaceutical industry, food industry, environmental protection industry, the electroplating industry. It can also be used in domestic sewage, industrial wastewater, dioxin gas purification, to smell. Decolorizing charcoal Physical characteristics: Activated carbon is a multi-aperture of carbide, a very rich pore structure, good adsorption properties, adsorption by its physical and chemical adsorption force made its appearance color was black. In addition to its main components carbon, also contains a small amount of hydrogen, nitrogen, oxygen, its structure is similar to a hexagon shape, due to the irregular hexagonal structure, but also to determine its multi orange body and high surface area Features, per gram of activated carbon has a surface area equivalent to 1,000 square meters have many. Decolorizing charcoal Material: decolorizing charcoal which mainly contains high amounts of materials made of carbon, such as wood, coal, nut shell, bone, and other petroleum residues. The wood / coconut shell / coal as the most commonly used raw material, under the same conditions, the wood / coconut shell activated carbon, active mass and other characteristics special is the best, because there is a larger surface area. Decolorizing charcoal production process: decolorizing charcoal production is generally divided into two processes, the first step, carbonization, the material is dried at a temperature of 170 to 600, the same amount to 80% r organic tissue charring. The second step, activation, the first step has been carbonized good carbonized material fed into the reaction, the reaction with the activator and water vapor, to complete the activation process and finished products. In an endothermic reaction, mainly produce CO and H2 gas composition for the carbonized material is heated to the appropriate temperature (800-1000 degrees), remove all of its biodegradable material, to produce a rich pore structure and huge surface area, activated carbon has a strong adhesive force. Different raw materials to produce activated carbon with different pore size, which is the raw material of coconut shell activated carbon smallest diameter, wood activated carbon also generally larger aperture, coal activated carbon pore size ranged between the two. Activated carbon pore size is generally divided into three categories: large hole: 1000-1000000A transition hole: 20-1000A microporous: 20A according to the above characteristics can be seen, for different adsorption objects need to choose the appropriate activated carbon to achieve best value for money Therefore, in the liquid phase adsorption in general, should be used more transition pore diameter and average pore diameter greater activated carbon. Decolorizing charcoal choice: In addition, please keep in mind when buying the smaller the particles, the better the effect. Because of its greater total surface area, the more the porosity. But also not too fine particles from powder, to avoid the inconvenience of use, affecting the filter filtering traffic. Generally preferred particle size of about 1mm diameter. Should be paid: decolorizing charcoal, although available to the removal of suspended solids in water quality, but it will soon be suspended voids clogging, but lost its original function. Therefore, it should be placed under the filter cotton, cotton filters let first dispose of suspended solids in water quality, hazardous substances soluble cotton filter can not handle and then by activated carbon treatment, but to prevent the particles are too small charcoal as filter Tailings water inflow inside the aquarium, as well as to be able to easily replace, it is best as a second layer of filter material to be placed, while the other filter materials, such as: biological filtration balls, ceramic rings and so placed thereon next.
