Gongyi City, Thailand clean water Material Factory for you to order release, preparation of aluminum sulfate: from bauxite and sulfuric acid pressurized reaction. Or sulfuric acid decomposition alunite, kaolinite and silica-alumina-containing materials can be obtained. Sulfuric acid bauxite grinding to a certain size, the addition of the reactor and the reaction of sulfuric acid, the reaction liquid aluminum sulphate for water treatment by sedimentation, the supernatant was added sulfuric acid to neutral or slightly alkaline, and then concentrated to about 115 ℃ edible Standard aluminum sulfate, aluminum sulfate was cooled to solidify, pulverized finished. Gongyi City, Thailand clean water Material Factory for you to order release: no iron aluminum sulfate preparation prepared using bauxite aluminum sulfate and iron-free silica superfine active approach. The preparation process bauxite grinding, magnetic separation to remove free iron source, and then reacted with sulfuric acid; adding the two dithiocarbamate solid high molecular weight multifunctional REACTION remove iron ions, filtered, and the filtrate is No iron aluminum sulfate. Respectively, with an alkaline aqueous residue, an aqueous surfactant solution, water washing to neutral, then, and after alkali reaction was filtered, and the filtrate, inorganic acids and active particle control agent reaction, filtered, washed and dried to obtain ultra-fine silica . The method has simple process, low cost and suitable for industrial production, ferric sulfate content of the preparation is less than 15ppm, active silica ultrafine particle size of 0.5 ~ 5um, the specific surface area greater than 200m2 / g, a tensile strength greater than 17.0 MPa, value-added advantages of aluminum sulfate particles | Jiaozuo aluminum sulfate | Thailand clean water provided by the Gongyi City, Thailand clean water plant material.
