[Introduction] Sanhe powdered activated carbon powder activated carbon appearance is dark black, has a good adsorption properties, good chemical stability, acid and alkali resistant, can withstand flooding, high temperatures. The specific surface area of ??up to 1000 to 1500 m2 / g, are porous hydrophobic adsorbent. Powdered activated carbon for dissolved organic matter such as: trihalomethanes and precursors, carbon tetrachloride, benzene, phenols chemicals have strong adsorption capacity; for color, smell, odor, methylene blue surface active substances, herbicides, insecticides, pesticides, synthetic detergents, synthetic dyes, amines and other chemicals are used to remove the effect of good; for mercury, aluminum, iron, nickel, zinc, cobalt, also have a strong adsorption capacity; but low adsorption of ammonia nitrogen removal. Many varieties of powdered activated carbon, mainly because a lot of raw material manufacture of powdered activated carbon, for example: wood, coconut shell, powder, coal, coke, bone, and other petroleum residue. Because some charcoal kinds of toxic substances in the water will precipitate, so carbon species in the water treatment industry is mainly used are: wood, coconut shell, coal char. Because different types of activated carbon in different processes, resulting in the distribution of the activated carbon surface elements and non-crystalline parts and various functional groups are different, which have a direct impact on the performance of activated carbon adsorption and surface diffusion rate of different organic compounds. Therefore, powdered activated carbon for water treatment in certain optimal scope. For different water quality, it is impossible to have a unified optimal carbon species, selected only on the basis of carbon analog static tests, taking into account economic factors, the choice of powdered activated carbon in order to choose the right kind of charcoal. After addition of powdered activated carbon used alone separation, recycling, regeneration more difficult, usually in conjunction with the water treatment sludge. [Introduction] Sanhe powdered activated carbon powder activated carbon adsorption can be made of different properties, different decolorization of different fineness grade activated carbon according to user requirements. Sanhe fast powdered activated carbon adsorption, flocculation effect and help filter effects. Less use of units of construction investment, low operating costs, and thus in water plants, sewage treatment plants favorites. In the field of food, medicine, bleaching, crystallization, filtration, purification and other substances with a wide range of uses. Activated carbon filter mat is mainly activated carbon foam material. [Sanhe powdered activated carbon Technical index Analysis Project Test Data Analysis Project Test Data Iodine value> 900mg / g methylene blue adsorption value ≥120mg / g specific surface area of> 1000 m / g water ≤8% PH value 5-7 packaging and storage: 25kg bags, plastic bags, the product should be stored in a dry place indoors, do not place damp. [Features] Sanhe powdered activated carbon is the main component of activated carbon carbon, carbon is about 90%, usually with a variety of plant debris (wood, coconut shell and bagasse, etc.) or the appropriate coal or charcoal as raw material, through a special The processing is made. There are a lot of charcoal inside very fine pores. Small diameter pores, so the total surface area is large, there is a strong adsorption capacity. Due to different materials and manufacturing methods, a considerable number of varieties of activated carbon, respectively, for different purposes. Sanhe powdered microporous activated carbon can adsorb gases and low molecular weight small molecules in solution, but the higher molecular weight molecules can not enter the pores; the hole provided into the pores of the channel, the higher molecular weight per se but also adsorption substance; macroporous channels are both provided and adsorption effect. If the activated carbon adsorption of small molecules, such as certain gases (gas) and low molecular weight organics, more porous products may be used; but if larger molecules to be adsorbed, will have to use products with more mesopores. Status of activated carbon pores, depending on the raw materials used in its composition, manufacturing methods and conditions. [Sanhe powdered activated carbon production methods] Sanhe powdered activated charcoal to high-quality raw materials, with a special production process is refined, there are physical, two chemical methods. First, the chemical method Sanhe powdered activated carbon Appearance: black powder, odorless, tasteless, not dissolved in the solvent in general. Performance: The quality of wood chips and powder as raw material, zinc chloride, phosphoric acid as an activator, after carbonization, activation refined, finished excellent adsorption capacity, low impurity content. Uses: Suitable for glucose sucrose, maltose and other refined carbohydrates bleaching phase, as well as citric acid, cystine, oil, chemical products macromolecular pigment removal, purification and refining. Second, the physical properties of powdered activated carbon Sanhe law: quality and powdery sawdust as raw material, after steam activation, refined handling, crushing, the appearance of fine black powder-like, non-toxic, tasteless, with a large specific surface area, adsorption ability. Sanhe shape powdered activated carbon products are mainly two types of powder and granular. Sanhe powdered activated carbon is a very fine powder, the majority can be passed through a 200 mesh screen, most through 325 mesh screen size powder in 1 ~ 150μm between (an average of about 40μm); typically, the more carbon black Fine, the greater the adsorption rate of its impurities. Gu Chang will be the height of the crushing and screening of activated carbon products, has been fine powder. Disadvantages of powdered charcoal is more difficult to regenerate, usually no more students use, so consumption is greater (in recent years, it also has studied the regeneration). Granular activated carbon regeneration usually use less consumption. It has not stereotypes two granular and columnar particle size between 0.5 ~ 4mm. The former is crushed and screened through appropriate obtained, which sucked raw press molding by a pelletizer. With sawdust as raw materials and the use of chemical activation Sanhe usually made of powdered activated carbon. Most of granular activated carbon from coal or charcoal as raw material, after crushing plus binders (such as coal tar, lignin sulfonate, etc.) is extruded through carbonization and activation treatment is made (or crumbled before activating the appropriate call granularity). [Sanhe powdered activated carbon quality and performance] Sanhe quality powdered activated carbon has a number of physical and chemical indicators, the major such as: moisture, ash, acid-soluble substance, the content of various metals and acid group, and its adsorption performance. For activated carbon, often used for different purposes in different materials and methods to test its adsorption properties, such as methylene blue adsorption, iodine adsorption, caramel adsorption, adsorption, etc. * quinine. Wherein the methylene blue adsorption is most commonly used. Methylene blue is a dark blue dye, it reflects the ability of the activated carbon adsorption of small molecules adsorbed material; activated carbon has a large number of pores, the higher this value. Caramel adsorption (or caramel or molasses adsorption rate) is a reflection on the adsorption properties of activated charcoal colored substance has a high molecular weight, good performance of activated carbon, this value reaches 100 to 110. [Sanhe powdered activated carbon transport and storage Precautions class powdered activated carbon materials are generally different from other activated carbon in the transport, storage and use. Sanhe powdered activated carbon is typically granular, its water, there are strict limitations. Logistics transport to prevent rain, heavy pressure, but also can not pile up too high. What matters specific details Sanhe powdered activated carbon should note the following: 1, Sanhe powdered activated charcoal transport and handling: activated carbon in the transport process, not with an iron hook drag should prevent substance mixed with hard, not strong vibration, friction, step, hit, throw prohibited, should care, and to reduce the fragmentation of carbon particles, affecting. 2, the use of powdered activated carbon Sanhe: first screening should be filled with dust nibs to produce because of transportation. Then the layers evenly spread, not from the feed directly into the hole, so as not to fill uneven particle size, and eventually drift gas, affect the results. Loading end, drove preceded blowing air, blowing carbon surface adhesion of dust, avoid dust after driving into the rear section of normal production. 3, non-flooding Sanhe powdered activated carbon: Activated carbon adsorption are porous substances, so the transport, storage and use of the process, we must absolutely prevent flooding, due to flooding, water filled pore activity, reducing the activated carbon direct contact with the gas surface area, seriously affect the results. 4, Sanhe powdered activated safety Notes: wet activated carbon required to remove oxygen from the air, in a closed container safe consumption of oxygen will cause a toxic environment, if the worker proceeds to contain a suitable low sampling or vessel containing the activated carbon Oxygen space operations, should comply with national standards and job specifications. 5. Fire Sanhe powdered activated carbon: Activated carbon during storage or transport, to prevent direct contact with the fire to prevent fire. Avoid regenerating activated carbon regeneration into oxygen and thorough, must be reduced by steam cooling after regeneration below 800 ℃, otherwise the temperature is high, the case of oxygen, carbon combustion. 6, Sanhe powdered activated carbon to prevent the tar substances: During use, should be banned sticky tar-like substance into the bed of activated carbon, activated carbon to avoid clogging the pores or cover the surface of activated carbon to start, so that gas can not expand the surface in contact with the activated carbon, lost application effects, such as a gas containing such substances, should be cleared of gas into the activated carbon bed (preferably with focal device other) in order to achieve good application effect. 7, Sanhe powdered activated carbon storage: Store in a cool dry place to prevent rupture of the inner and outer bag to prevent moisture absorption and other substances in the air, affect the results. With no toxic gases or volatile substances mix, stored away from sources of pollution.
