The characteristics of the six ring carbon irregular arrangement, resulting in the Coal columnar activated carbon coal columnar micropore volume and surface area. Coal columnar activated carbon can be made from many kinds of material containing carbon, including wood, sawdust, coal, coke, peat, lignin, stone, hard Nutshell, sucrose pulp, bone, lignite, petroleum residues, etc. These substances. Wherein the coal and coconut shell has become the most commonly used raw material for manufacturing columnar activated carbon from coal. QUALITY manufacturing a columnar activated carbon is basically divided into two processes, the first process including dehydration and carbonization of the raw material is heated and dried at a temperature of from 170 to 600 ℃ make about 80% of the original organics carbonization. The second process is the activation of the carbonized product, this is accomplished via an activating agent such as water vapor and carbon reaction, to generate a mixed gas composed of CO and H2 in an endothermic reaction mainly for combustion carbonized product is heated to a proper temperature (800 to 1000 ℃), in order to burn except where all the decomposable material, thereby generating developed porous structure and a great specific surface area, and thus has a strong adsorption capacity. The porosity of coal columnar activated carbon can be divided into three categories according to the size of the aperture. Big hole: Radius 1000 - 1000000 A. Transition hole: Radius 20 - 1000 A. Microporous: radius - 20 A. QUALITY columnar activated carbon made by different materials having a different aperture size. Made by coconut shell coal columnar activated carbon has the smallest pore radius. Wood the QUALITY columnar QUALITY columnar activated carbon typically has a maximum of the pore radius, and they are used for adsorption of larger molecules, and almost exclusively in the liquid phase. Coal columnar activated carbon for the first type of granular coal columnar to use in the field of water treatment in the city that is made of wood, called charcoal. Coal columnar coal columnar activated carbon pore size in between. In on QUALITY columnar QUALITY columnar activated carbon, lignite QUALITY columnar QUALITY columnar activated carbon than anthracite QUALITY columnar QUALITY columnar activated carbon has a transitional porosity and larger average pore size, and therefore can effectively remove the water and organic macromolecules. Usually QUALITY columnar QUALITY columnar activated carbon used in water treatment, its surface area is not necessarily be too large, but should have a transitional porosity and larger average pore size. Japanese market sale of some of the liquid phase 10 QUALITY columnar QUALITY columnar activated carbon having the following characteristics: specific surface area of ??850 to 1000m2 / g, a pore volume of 0.88 to 1.5 ml / g, and an average pore radius of 40 to 50A. Coal columnar activated carbon adsorption performance in the production process, to improve the only way is to control the production process, so that the unit volume is increased as much as possible within QUALITY columnar activated carbon pore structure. So higher adsorptive QUALITY columnar activated carbon contains a large number of pores, so that its density is becoming smaller, which is why adsorbing better feel more light columnar activated carbon from coal reasons (provided using the same kinds of raw materials production, water-soaked or adsorption of other substances). The same time as the higher production costs of coal columnar activated carbon adsorption increased, and is growing exponentially, which is useful for the market low adsorption coal columnar activated carbon posing the high adsorption Coal columnar activated carbon sales motivation. Order to unify the standards, production control, coal columnar activated carbon industry is usually calibrated iodine adsorption value or adsorption value of carbon tetrachloride (CTC) coal columnar activated carbon adsorption value, the higher the adsorption value, coal columnar The adsorption capacity of the activated carbon is the stronger. Understand the above points, it is not difficult to determine the performance quality of the coal columnar activated carbon. The adsorption value the higher the coal columnar activated carbon the better the performance. Then how simple case of testing equipment to identify the level of coal columnar activated carbon adsorption value it? Here are a few relatively easy method for reference. 1, directly see the indicators provided by the manufacturer. QUALITY columnar activated carbon commonly used adsorption indicators are: iodine adsorption value, the absorption value of carbon tetrachloride (CTC), a methylene blue adsorption value, and an iodine adsorption value is used to indicate a columnar activated carbon from coal liquid substance adsorption capacity, tetrachloride Carbon adsorption value is used to indicate the columnar activated carbon from coal for the adsorption capacity of gaseous material, the methylene blue adsorption value is used to indicate the columnar activated carbon from coal decoloring ability. Three higher the index, the stronger that coal columnar activated carbon adsorption capacity. Therefore everyone can buy coal columnar activated carbon combined according to their own use of these indicators provided by the manufacturer to buy coal columnar activated carbon for their own purposes. 2, to see the volume: the same 12 packs * 50g = 1 box why the volume of the original ecological coal columnar activated carbon than other home it? Coal columnar activated carbon has been described above, in order to improve the adsorption properties only as much as possible in the coal columnar activated carbon manufacturing pore structure, porosity more coal columnar activated carbon is more crisp, relative density, there would be more light so good on the feel of coal columnar activated carbon will be relatively light in the case of equal weight, packaging, performance good coal columnar activated carbon than low-grade coal columnar activated carbon volume much bigger. 3, see bubbles. A small QUALITY columnar activated carbon into the water, due to permeation of water, the water will gradually immersed in the the QUALITY columnar activated carbon pore structure, forcing the air in the pores of the discharged, thereby generating a series of extremely fine bubbles in the water Pull a tiny bubble line, will be issued to the slightest sound of bubbles, very interesting. This phenomenon occurs more vigorously, the longer the duration, QUALITY columnar activated carbon adsorption, the better. 4, see decolorization ability. Another manifestation of the coal columnar activated carbon adsorption capacity is bleaching capacity, coal columnar activated carbon has the uncanny ability colored liquid can be turned into light-colored or colorless, which is actually a pigment molecules colored liquid coal columnar activated carbon adsorption causes. Because of this characteristic of coal columnar activated carbon, is widely used in the field of sugar industry in the brown sugar becomes the sugar production process. Take two transparent cups, placed in a cup of pure water, and then drop of red ink (where you can use any kind of easy to observe but does not change the nature of the pigment of the water can be, for example, blue ink color printer ink but you can not use ink and carbon ink), half colored water will pour another cup Stir reserved comparative samples. Half of the coal columnar activated carbon into the colored water, the number should reach water or more, this effect will be more obvious, to stand for 10-20 minutes and contrast water samples were compared, the stronger the effect under the same conditions, the decolorization description Coal columnar activated carbon adsorption, the better. Buy coal columnar activated charcoal should also pay attention to the following points: 1, the best coal columnar activated carbon packaging is sealed packaging. More or less in the air was filled with a variety of organic macromolecules, especially as storage lockers near the store or at home in the newly renovated great concentration of phenolic substances, these substances will be coal columnar activated carbon adsorption can not even use, over time, the coal columnar activated carbon adsorption performance due to adsorption of these substances reduced. Coal columnar activated carbon performance of the more more coal columnar activated carbon adsorption value should be sealed packaging to prevent outside interference. Now appearing on the market of fake coal columnar activated carbon and some coal columnar activated carbon semi "charcoal" posing the carbonized material only after the "activation" process to become a real coal columnar activated carbon activation process precisely coal The most important manufacturing process of the pore structure in the mass columnar activated carbon manufacturing processes. This process is the lack of charcoal can be said that almost no adsorption performance, consumers suffer shallow. Carbonized material not activated pore-forming process, so the surface than coal columnar activated carbon is smooth, and the color white, slightly metallic luster than coal columnar activated carbon hard feel, and the weight is much heavier. A considerable part of the counterfeit QUALITY columnar activated carbon using the inferior material doped celite firing, its carbon content is extremely low, the majority of non-active substances, such carbon color relatively white, feel very heavy particle length longer, the intensity is high, will be issued crisp sound similar ceramic percussion collide with each other, break apart by hand will find the section on the fine white particles, coal columnar activated carbon is an excellent adsorbent, it is the use of charcoal , charcoal, various pericarps and quality coal as a raw material, the raw material is crushed by physical and chemical methods, sieved, catalyst activation, rinsing, drying and screening a series of machining processes is made which has a physical adsorption and adsorption of gas phase, the dual characteristics of chemisorption can choose a variety of substances in the liquid phase, in order to achieve the bleaching refining, disinfection and deodorization and decontamination purification and other purposes. inspection standards in accordance with GB of powdered coal columnar activated carbon usage is as follows: 59.8% for medicine for oral glucose 26.6% for the food industry accounted for 10.8% for the other aspects of the accounting for 2.8 percent of particles coal columnar activated carbon usage is as follows: 51.2% for synthetic fiber carrier 13.0% PVC carrier for air, water purification 23.5% for synthetic the desulfurization accounted for 7.7% to 4.6% other large domestic coal columnar activated carbon manufacturers, coal columnar activated carbon Selection coal the qualitative columnar activated carbon regeneration, coal columnar activated carbon recovery services. leading products - solvent recycling coal columnar activated carbon carrier coal columnar activated charcoal, coconut shell coal columnar activated carbon, wood granular activated carbon, coal columnar coal columnar activated carbon air purifying coal columnar activated carbon, the super capacitor charcoal, gasoline, oil and gas adsorption recovery carbon and other.
