Uses of Xintai Group's calcium aluminate powder for water purifier
2022-11-10
What are the basic information and key ingredients of calcium aluminate powder and bauxite of Xintai Group selected by water purifier?
The main ingredients of calcium aluminate powder: alumina trioxide, active calcium, compound
Calcium aluminate powder for water purifier: 50-55% of alumina
Product model: Powder 150-200 mesh.
Water purification agent with calcium aluminate powder product characteristics: Xintai Group's calcium aluminate powder and inorganic strong alkali reaction activity is very high, in the room temperature state can be run to produce. And the heat release is large, the temperature rise is fast, and the dissolution rate of aluminum trioxide can reach above 90%. Uses of Xintai Group's calcium aluminate powder: It is used to produce aluminum chloride, aluminum sulfate, sodium aluminate and other aluminum salt goods. It can be used for the change of alkalinity, and it can also be used for refractory insulation material.
Calcium aluminate powder technical index formula water purifier bauxite information appearance: reddish brown
Bauxite composition: AL2O3, Fe2O3, CaO
Water purifier bauxite AL2O3 composition: 30-35%
Specification: 180-300 mesh
Characteristic: heat resistance, corrosion resistance, stable quality
Water purifier bauxite main use: used for water purification agent convergence sodium cyanate production
Water purification agent with calcium aluminate powder and bauxite combination key production what goods?
One, the raw material of polymeric aluminum chloride is Xintai Group's calcium aluminate powder, sulfuric acid, bauxite cement clinker, which is mainly used in wastewater treatment level. For the treatment of domestic water, there are clear regulations on heavy metal overload, so whether it is raw materials or production and processing process milky white polymeric aluminum chloride is better than dark brown polymeric aluminum chloride. Light yellow aluminum chloride polymerization is generally produced by drum drying or spray tower dry manic production into a block, powder two kinds of solid way.
Second, polymeric aluminum chloride iron dark brown raw materials are calcium aluminate powder, sulfuric acid, bauxite and iron powder. The production and processing process is drum drying method, generally mainly used in wastewater treatment level, it is added with fans so the tone is dark brown, the larger the fan used the heavier the tone, the fan more than a certain amount in many cases is also known as ferric aluminum chloride polymerization, in wastewater treatment waking surface with excellent practical effect.
Through flocculation experiments found that when the alkali base degree of flocculant is around 75% and the pH value of aqueous solution is 7-9, the flocculation performance of iron polymeric aluminum chloride is good. By using low-grade bauxite containing iron as the main raw material and adding appropriate amount of calcium aluminate powder, the flocculant ferric polymerized aluminum chloride was prepared. The factors affecting the preparation of ferric polymerized aluminum, such as hydrochloric acid concentration, hydrochloric acid dosage, temperature and calcium aluminate powder dosage, were systematically studied to obtain the optimized conditions for the preparation of ferric polymerized aluminum, and the flocculant was used in the treatment of actual industrial wastewater.
