Powdered activated carbon materials, properties and applications: powdered activated carbon to high-quality wood, coconut shell, coal as raw materials. After steam activation, the refined treatment and crushing, the appearance of fine black powder, non-toxic, tasteless. Powdered activated carbon having a large surface area, filtration speed, high adsorption capacity, filtration speed, bleaching addition to taste strong, durable economic advantages, which are widely used in medicine, food additives, MSG, chemicals, beverages, sugar, oil and other products bleaching, cleaning, fine for water purification. In brewing, sewage treatment, power plants, electroplating and other fields are also more common. Powdered activated carbon alone after separation, recovery, regeneration more difficult, usually in conjunction with the water treatment sludge. Second, the technical indicators: Size (mesh) iodine value mg / g caramel force (%) methylene blue decolorized (m1) iron salts (%) PH value Ash (%) The main purpose ≤80 ≥900 ≤4 bleaching liquor, Refined ≤ 200 ≥100 ≤0.05 3-5 ≤4 sugar bleaching, refining ≤100 ≥950 ≥10 ≤0.05 ≤4 vitamins, monosodium glutamate food, medicines, bleaching ≤100 ≥900 ≥7 ≤12 types of sewage purification treatment ≤ 100 ≥950 ≤5 chemical reagents, fine chemical products bleaching Third, the application areas 1 and beverage products with activated carbon with sawdust as raw materials, a unique phosphoric acid production process is refined, has developed in the pore structure, high adsorption capacity, fast filtration characteristics. Mainly applicable to purification of various cola, fruit juice, wine and other beverages as well as drinking water. 2, water treatment because of its excellent void structure, strong adsorption bleaching ability, in water treatment with activated carbon powder activated carbon, wide field of sewage treatment applications. 3, sugar, oil and other food products and food additives with activated carbon with sawdust as raw materials, a unique phosphoric acid production process is refined, has a larger surface area, with a strong adsorption capacity, stable performance indicators. Mainly used in sugar, fat, food additives, chemical additives, fuel intermediates, pharmaceutical formulations of high pigment solution bleaching, purification, deodorizing, cleaning and so on. 4, the amino acid glutamate (MSG) of the product gap with charcoal reasonable structure, high adsorption capacity, strong bleaching capacity, filtration speed, widely used in a variety of amino acid industry, such as sodium glutamate, an amino acid phenylalanine and other products bleaching, purification, deodorizing, cleaning and so on. 5, injection, medicinal products activated carbon that fewer impurities, high purity, filter fast, with excellent bleaching, purification and properties, mainly used for various injection pharmaceutical bleaching, refining and out of the heat source, but also for vitamins and other bulk drugs, intermediates of bleaching and refining. 6, electroplating with activated carbon products use wood or coconut shell as raw materials, high temperature steam activation physical method is refined, there are two kinds of granular and powdered, having a large surface area, strong adsorption capacity, high mechanical strength, the surface containing Oxygen gene more active and strong advantages, can be used for purification of the plating solution, chromium plating wastewater treatment, with a variety of uses cyanide wastewater treatment and so on. 7, waste incineration The products use wood or charcoal as raw coal quality, reasonable pore structure, dioxins and other polluting gases produced by waste incineration has a good adsorption capacity, widely used in power generation and waste incineration areas of solid waste incineration .
