Shenzhen calcium aluminates

Calcium aluminates powder is gray powder. Main ingredients are two calcium aluminates (CaO · 2 A1203) and a calcium aluminates (CaO · A1203) mixture. Slightly soluble in water, water solution is alkaline, PH value of about 11.

Calcium aluminates powder and inorganic acid reaction activity is very high, in room temperature can start happening. And put large quantity of heat, temperature quickly, the aluminum oxide dissolution rate of 90% above, use it to make raw material to produce liquid or solid polymerization aluminium can simplify process and reduce the cost, improve product quality, is the most manufacturers at home and abroad into the polymerization of raw materials.

Application:

Calcium aluminates powder mainly for the production of polymerization aluminium, aluminium, aluminium acid sodium and aluminium salt products. Can also be used to alkalize degrees adjustment, but also can be used for refractory materials.

Quality standard:

At present, there is no uniform quality standards, its production test and are at my company O/GWDGS001-1999 standard execution.

Method of use:  

Calcium aluminates powder and hydrochloric acid reaction, can step into the polymerization. Mix press type calculation:

WHcl = [2.147 (1-B) · AAlo, · n ten 1.304 Acao]. W/AHC

Production, the first reaction pool water, open mixing paste. And then quantitative join hydrochloric acid, dilute concentrations to requirements, then slowly add calcium aluminates powder was reaction. The reaction process, the temperature will gradually increasing in the pool. More than 110 ℃. But right amount water inhibition. The reaction from intense and excessive pool. Add water to fill a few times. Maintain normal temperature is required. Add the calcium aluminates powder, again reaction 2 hours, with PH dipstick test more than 3 when, can add water dilute to density of 1.25-1, 26, feeding to sediment basins precipitation, the upper clear liquid that is for liquid product, also can be the dryer in dry, get solid polymerization aluminium products.

 Transportation, packaging and storage:
The products using plastic woven bag packaging, the net weight of each bag is 50 + 1 Kg
Transportation and storage should maintain dryness. Waterproof, moistureproof. If encounter water agglomerate, shall be subject to the processing of the reoccupy after.
