[Calcium stearate supply and procurement] Calcium stearate plays an important role in cement

1.jpg

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

Supplier of calcium stearate points out: Calcium stearate is widely used, and it also plays an important role in cement:

Waterproofing agent: Fireproof insulation sheets produced with calcium stearate basically do not absorb moisture when exposed to water. It can reduce transportation costs during transportation and save manpower and material resources during 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 diameter fine and uniform, without large or small holes, so that the cement foam insulation board foams There will be no collapse at any time, and there will be no holes or cracks on the surface and inside of the semi-finished product after foaming is completed.

Curing agent: Calcium stearate itself has a large amount of calcium ions, which can effectively increase the strength of the fireproof insulation board and prevent the powder of the fireproof insulation board from folding out. Fireproof insulation produced with calcium stearate In the later stage, the board will become stronger and stronger due to the chemical reaction of calcium ions.

Calcium stearate is mainly used as a foam stabilizer, curing agent and waterproofing agent for fireproof insulation boards in cement foaming. At present, the formulas used by various manufacturers to produce cement foam fire insulation boards are different. There are sulphoaluminate cement and ordinary Portland cement. Different cements require different quality and dosage of calcium stearate per cubic meter of fireproof insulation board produced.
