【Calcium stearate supply procurement】Does calcium stearate play a big role in cement?

Calcium stearate white powder, insoluble in water, cold ethanol and ether, soluble in organic solvents such as hot benzene, benzene and turpentine, slightly soluble in hot ethanol and ether. When heated to 400 ° C, it decomposes slowly, is flammable, decomposes into stearic acid and corresponding calcium salts in case of strong acid, and is hygroscopic.

Beite Chemical, which supplies calcium stearate, points out that calcium stearate is widely used and plays an important role in cement:

Waterproof agent: the fireproof insulation sheet produced by calcium stearate basically does not absorb water when encountering water, which can reduce transportation costs during the transportation process and save manpower and material resources in the installation stage.

Foam stabilizer: calcium stearate effectively prevents the liquid material of the fireproof insulation board from rising too high and insufficient, and keeps the pore size fine and uniform, there is no large and small bubble holes, so that the cement foam insulation board does not collapse when foaming, and there are no holes or cracks in the semi-finished product after the foaming is completed.

Curing agent: calcium stearate itself also has a large number of calcium ions, it can effectively increase the solid strength of the fire insulation board, prevent the fire insulation board powder from folding out, the fire insulation board produced with calcium stearate in the later stage with the chemical reaction of calcium ions will become more and more firm, more and more solid.

Calcium stearate is mainly used as a foam stabilizer, curing agent and waterproof agent for fireproof insulation boards in cement foaming. At present, the formulas used by various manufacturers to produce cement foaming arson insulation boards are not the same. There are aluminum sulfate cement, there are also ordinary Portland cement, different cement, the production of each cubic meter of fire insulation board for calcium stearate quality and dosage is not the same.
