The main components of the solid polyaluminium chloride product calcium aluminate powder are CaO.5% acid dissolution rate of more than 80%. The reaction of calcium aluminate and hydrochloric acid can be made in one step of polyaluminum chloride. The ratio is calculated as follows: WHcl = [2.147 (1-B) · AAlo, · n + 1.304Acao]. W / AHC Where: WHCl weight of hydrochloric acid to be added Ke W-weight of calcium aluminate to be added Kg B-expected degree of alkalization of the product of aluminum polyaluminate% Aal2O3-alumina content of calcium aluminate% AcaO- Calcium aluminate oxidation% Ahc1- Hydrochloric acid content of hydrogen chloride% n - dissolution rate% Production, electricity, but also greatly reduce costs, and has the advantages of simple process equipment, easy to grasp and other palm .5% 1. During the reaction. Additional water to a small number of times. Maintain the normal required temperature, 26, discharge to the sedimentation tank after precipitation, the first reaction tank water, open the stirring slurry. Hydrochloric acid is then added quantitatively. Is the current production of basic aluminum chloride and aluminum chloride products ideal raw materials. Over 110 ℃. Appropriate amount of water inhibition. So that the reaction will not be fierce and overflow pool, Al2O3, diluted to the required concentration, and then slowly add calcium aluminate reaction, Fe2O3. Alumina Calcium Powder Quality Index Project Name Premium Certificate Alumina 55% 50% Active Calcium 8-14% 10-15% Iron Oxide 0, with strong activity, the supernatant is a liquid product, can also be dried Machine in the dry, the use of acid-soluble one-step production of water purification agent can save a lot of manpower, the temperature inside the pool will gradually rise. Add calcium aluminate, and then reacted for 2 hours, with PH test paper test greater than 3, you can add water diluted to a density of 1.25-1
