Activated clay (bleaching earth), is made from natural bentonite, attapulgite clay, sepiolite or attapulgite clay mineral powder made by artificial activation. Production of activated clay is generally used inorganic acid activated bentonite, according to the process conditions can be divided into dry, wet and semi-wet. Dry the acid is sufficiently mixed with a small amount of bentonite, a predetermined time, and then dried, pulverized activated clay that is made. The process is simple, low cost, no pollution. Since the hard dispersed bentonite acid, and salts formed by the reaction can not be removed, the product quality is generally poor. Is wet with water, acid, and a certain proportion of bentonite in the reactor were mixed and heated at about 100 ° C 2-6 hours, then washed, dried, pulverized activated clay. The advantages of this process are: reaction uniform, full, product stability, bleaching power, is the main method of making efficient activated clay; their drawbacks: acid consumption volume, high cost and environmental pollution. Now the wet production process of activated clay was studied, that is to cause a high concentration of the appeal disadvantage acid in the reaction solution, washed with difficulty scientific washing process, a large number of acid and aluminum salts and the reaction mixture was washed with water containing no recycling. We fully recovered and the reaction mixture was washed with water, washed with bentonite for activation and product cycle, reproduction, while the production of aluminum sulfate, activated clay, so the utilization of 96% sulfuric acid, 20% water wet process in general usage, production cost reduction of 25%, to solve the water pollution problem. Bentonite is a natural aluminum silicate, formed due to the different conditions, different origin even in the same mine mine bentonite different composition, structure, physical and chemical properties are some differences. That's all about the activated clay cleaner production processes. With more content, please click on the activated clay www.zbzhengtian.com
