The six ring carbon irregular arrangement, resulting in a characteristics of coal columnar coal activated carbon column microporous volume and high surface area. Coal activated carbon column may be many kinds of carbon-containing material made of these materials, including wood, sawdust, coal, coke, peat, lignin, stone, hard shell, sugar pulp, bone, lignite, petroleum residue. Coal and coconut shell has become the most commonly used raw material for the manufacture of coal columnar activated carbon. Coal columnar activated carbon manufacturing is basically divided into two processes, the first process comprises the dehydration and carbonization, the raw material is heated and dried at a temperature of 170 to 600 ° C. The carbonization, about 80% of the original organic matter. The second process is the activation of the carbonized material, and this is accomplished through the use of activators such as water vapor and carbon reaction, to produce a mixed gas consisting of CO and H2 in the endothermic reaction is mainly used for burning charcoals heated to an appropriate temperature (800 to 1000 ° C), burning all biodegradable material, the resulting developed porous structure and huge specific surface area, which has a strong adsorption capacity. Coal columnar activated carbon pore size of the aperture can be divided into three categories. Macroporous: Radius 1000 - 1000000 A. Transition pore: Radius 20 - 1000 A. Microporous: Radius - 20. Coal columnar activated carbon made from different materials with different pore sizes. Coal columnar activated carbon from coconut shell has the smallest pore radius. The wood coal columnar coal columnar activated carbon having a maximum pore radius Usually, they are used for the adsorption of larger molecules, and is used almost exclusively in the liquid phase. Used in the field of water treatment in the city to the first type of granular coal columnar coal activated carbon column is made of wood, called charcoal. Coal columnar coal columnar activated carbon pore size in between. Coal columnar coal columnar activated carbon, lignite coal columnar coal activated carbon column has more transition pore and larger average pore size than anthracite coal columnar coal columnar activated carbon can effectively remove organic molecules in water. The general coal columnar coal columnar activated carbon used in water treatment, its surface area is not necessarily too large, but should have more transition pore and larger average pore size. Japan Market Complex, sold some of the liquid with coal columnar coal columnar activated carbon has the following characteristics: 850 to 1000m2 / g specific surface area, pore volume of 0.88 to 1.5 ml / g, an average pore radius of 40 to 50A. In the production process, improve coal columnar activated carbon adsorption performance the only way is to control the production process, per unit volume as much as possible to increase the pore structure of coal activated carbon column. Thus, the higher the adsorbing coal columnar activated carbon because it contains a large number of pores, so that its own density becomes increasingly small, which is why the lighter texture better adsorbing coal columnar activated carbon reason (presupposes the use of the same kinds of raw materials, production, soaked in water or other substances adsorption). Coal columnar activated carbon at the same time as the adsorption increased production costs, the higher, and is growing exponentially, which is useful in the market low adsorption coal columnar activated carbon posing high adsorption coal columnar activated carbon sales motivation. Order to unify the standards, the production control, usually coal columnar activated carbon industry with iodine adsorption value or carbon tetrachloride adsorption value (CTC) to calibrate the coal columnar activated carbon adsorption value, the higher the adsorption value, coal columnar the stronger the adsorption capacity of the activated carbon. Understanding of 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 in the case of non-detection equipment how easy it is to identify the level of coal columnar activated carbon adsorption value it? Here are some easy methods for reference. A direct look at the indicators provided by the manufacturer. Coal columnar activated carbon commonly used adsorption index: Iodine adsorption, adsorption of carbon tetrachloride (CTC), methylene blue adsorption, iodine adsorption value used to represent the coal columnar activated carbon adsorption capacity of the liquid substance, tetrachloride carbon adsorption value used to represent the coal columnar activated carbon adsorption capacity of the gaseous substances, methylene blue adsorption value is used to indicate coal columnar activated carbon decolorization. These three indicators are an indication that the stronger coal columnar activated carbon adsorption capacity. So we can buy coal columnar activated carbon combined according to their use of these indicators provided by the manufacturer to buy for their own use coal activated carbon column. 2, see Volume: the same 12 pack * 50g = 1 box why the original ecological coal columnar activated carbon than other stores bulky it? Has been described above, in order to improve the coal columnar activated carbon adsorption performance, only as much as possible in the coal columnar activated carbon manufacturing pore structure, porosity more coal columnar activated carbon is more crisp, the relative density of the more light the feel of a good coal columnar activated carbon will be relatively light, in the case of the same weight packaging, performance coal columnar activated carbon is much larger than the volume of low-grade coal columnar activated carbon. 3, see the bubbles. A small coal columnar activated carbon into the water, due to the infiltration of the water, the water will gradually immersed in the pore structure of coal columnar activated carbon, forcing the air in the pores is discharged, thereby generating a series of extremely fine bubbles, pull in water a small bubble line, and will be issued slightest sound of bubbles, very interesting. This phenomenon occurs more intense, longer duration, coal columnar activated carbon adsorption, the better. 4, see the decolorization ability. Another manifestation of the coal columnar activated carbon adsorption capacity is bleaching ability, coal columnar activated carbon can be colored liquid into a light-colored or colorless magical ability In fact, this is because the coal columnar activated carbon adsorption of colored liquid pigment molecules the causes. Because of the characteristics of the 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, pure water into a cup, and then dropped into a drop of red ink (pigment can be any kind of easy to observe but does not change the nature of the water, for example, in blue ink, the printer color ink, but can not use ink and carbon ink) Stir half of the colored water will pour another cup aside for control sample. Coal columnar activated carbon into the colored water, quantity of water should reach 50% or more, this effect will be more obvious, let stand for 10-20 minutes after contrast water samples were compared under the same conditions, bleaching effect is stronger coal columnar activated carbon adsorption as possible. Buy coal columnar activated carbon should also pay attention to the following points: 1, coal activated carbon column packing is best sealed packaging. More or less in the air was filled with a variety of organic macromolecules, especially as great near shops or at home in the newly renovated cabinets phenolic concentration of the substance, these substances will be coal columnar activated carbon adsorption , over time, coal columnar activated carbon adsorption performance because of the adsorption of these substances reduce or even unusable. More more high adsorption coal columnar activated carbon should be in a sealed package to prevent coal activated carbon column performance outside interference. 2, now appearing on the market of fake and coal columnar activated carbon took the coal columnar activated carbon semi-carbonized material posing carbonized material only after activation process in order to become a real coal columnar activated carbon, the activation process is coal quality columnar activated carbon manufacturing process is the most important manufacturing process of the pore structure. The lack of this process carbonized material can be said that almost no adsorption properties, make consumers suffer not shallow. Carbonized material in the absence of activated pore-forming process, the surface smooth than coal columnar activated carbon, and the color is white, slightly metallic luster and feel than hard coal columnar activated carbon, and the weight of many. There are a considerable part of the fake and coal columnar activated carbon used inferior materials mixed with diatomaceous earth firing, very low carbon content, the majority of non-active substances, carbon color than white, feel very heavy particle length longer, the intensity is high, collide with each other will be issued similar ceramic crisp sound when struck, break apart by hand will find the section on the white fine particles of coal columnar activated carbon is an excellent adsorbent, it is the use of charcoal charcoal, husk and quality coal as the raw material, the raw material by physical and chemical methods was crushed, sieved, activation of the catalyst, rinsing, drying and screening of a series of machining processes is made which has a physical adsorption and the dual characteristics of chemical adsorption, the adsorption of gas and liquid in a variety of substances, in order to achieve the purpose of bleaching refining, deodorization disinfection and decontamination and purification. inspection standards in accordance with Chinese GB of powdered coal columnar activated carbon use as follows: for medicine (59.8%) for oral glucose (26.6%) for the food industry accounted for 10.8% used for other purposes accounted for 2.8% of the particulate coal columnar activated carbon usage is as follows: 51.2% for synthetic fiber carrier with on the PVC carrier accounted for 13.0% for air, water purification for the synthesis of desulfurization 7.7% 4.6% large domestic coal columnar activated carbon manufacturers of 23.5%, coal activated carbon column selection, coal quality columnar activated carbon regeneration, coal columnar activated carbon recovery of its leading products - solvent recovery coal columnar activated carbon carrier coal columnar activated carbon, coconut shell coal columnar activated carbon, wood granular activated carbon, coal columnar coal columnar activated carbon, air purification coal columnar activated carbon, super capacitor charcoal, gasoline oil and gas adsorption recovery carbon.
