Xintai Group: Tell us how to use calcium aluminate powder

2022-08-15

Calcium aluminate powder reacts with hydrochloric acid to make polyaluminium chloride in one step. Before production, add water to the reaction pool and open the stirring pulp. Subsequently, add sulfuric acid in quantitative analysis, dilute the liquid to the specified concentration value, and then slowly add calcium aluminate powder to carry out the reflection. During the reaction process, the ambient temperature in the pool will gradually rise. Beyond 11 ℃, the appropriate water can be added to suppress, so that the reflection will not be violent and overflow pool. Adding water should be small amount and more meals. Maintain the normal ambient temperature needed. Add full calcium aluminate powder, reflect again for 2 hours, and when it exceeds 3 with PH test paper, you can add water to dilute the liquid to a relative density of 1.25~1.26, and after feeding to the sedimentation pond for deposition, the upper clear liquid is the liquid commodity, which can also be dried and manicured by the dryer to obtain solid polyaluminium chloride commodity.

Calcium aluminate powder is mainly used in the production of aluminum salts such as polyaluminum chloride, aluminum sulfate, calcium aluminate and other commodities. It can also be used as the adjustment of alkalinity, and it can also be used as refractory insulation material.

Xintai Group: Storage and transportation of calcium aluminate powder

Because calcium aluminate powder will be chemically changed after contacting with gas, therefore, when transporting and storing, it should make the equipment in a dry and naturally ventilated environment, and be waterproof and moisture-proof. If it has been agglomerated, it needs to be processed and then used.

Xintai Group: Talking about the advantages of calcium aluminate powder and its standard use

Calcium aluminate powder is mainly used in the production and manufacture of aluminum salts such as polyaluminum chloride, aluminum sulfate, sodium aluminate and other commodities. It can be used for the adjustment of alkalinity, and it can also be used for refractory insulation materials. Calcium aluminate powder is grayish white powder. The main component is a mixture of calcium dibasic aluminate (CaO-2A1203) and calcium monoaluminate (CaO-A1203). Slightly soluble in water, the solution is alkaline, PH value is about 11, choose plastic woven bag packaging, each bag net weight 50Kg, transportation and storage should be kept in dry. Moisture-proof and waterproof. If clumped after meeting water, need to be solved before use, calcium aluminate powder and inorganic strong alkali reaction activity is very high, at room temperature state can run to produce. It can be used as raw material to produce liquid or solid polyaluminium chloride to optimize the processing process, control the cost and improve the product quality.

The reaction of calcium aluminate powder with hydrochloric acid can produce polyaluminium chloride in one step, when used, first add water to the reaction pool and open the stirring slurry. Then add sulfuric acid in quantitative analysis, dilute the liquid to the specified concentration value, and then slowly add calcium aluminate powder to carry out the reflection, during the reaction, the ambient temperature in the pool will gradually rise, beyond 110 ℃. Appropriate water can be added to suppress. So that the reflection is not violent and overflow pool, replenish the water to a small amount of more meals. Maintain the normal need for ambient temperature, the application of adding calcium aluminate powder, and then reflect 2 hours, with PH test paper test more than 3, you can add water to dilute the liquid to the relative density of 1.25-1.26, after feeding to the sedimentation pond deposition, the upper clear liquid that is liquid goods, but also by the dryer in dry, to obtain solid polyaluminum chloride goods.
