Ningxia Huiheng activated carbon Sales Co. Ltd. Anthracite under the conditions of isolated air, heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, solidification, shrinkage and other stages and then made coke, this process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Due to its high mechanical strength, porous structure, good adsorption performance, strong ability to cut pollution, fast filtration speed, long service life and so on. The utility model is suitable for domestic water and industrial water treatment devices. 1.High mechanical strength, broken rate and wear rate of less than 2% (percent by mass). 2. Fixed carbon is greater than 80%, mud content is less than 1.5, the use of long cycle. 3. Product appearance of good gloss, moisture is less than 2.5%, porosity greater than 75%, filtration speed. 4. Chemical stability, non-toxic substances. In the general acidic, alkaline, neutral water are not dissolved. 5. Particles uniform, large gap, low resistance, porous structure is reasonable, good adsorption performance, strong ability to intercept sewage.
