Cement foaming agent is very important in our production and processing of a kind of product so we commonly used cement related what kinds of the foaming agent, then we can do some simple introduction for you.
Cement foaming agent has the following kinds: azo compound 1.
It is a kind of yellow powder, non-toxic, odorless, not easy to burn, soluble in alkali, and insoluble in gasoline, alcohol, benzene, pyridine and water.
Diisopropyl di-isopropyl (DIPA) orange oil liquid, soluble in almost all organic solvents and plasticizers, insoluble in water.
Azo diisobutyronitrile (ABN or ABIN) colorless, odorless white crystalline powder, soluble in ether, vinyl chloride monomer, slightly soluble in methanol, insoluble in water.
Azo and barium carboxylic acid barium (2) nitrogenous compounds 1.
N, N' - nitro pentamethylenediamine (DPT) light yellow crystalline powder, no stink, but the moisture has the formaldehyde flavor.
This product is flammable and cannot be stored with acidic substances.
DPT insoluble in ether, slightly soluble in water, alcohol, slightly soluble in chloroform, soluble in acetone, ketone, etc.
N, N'- dimethylaminamide (NTA) and 30% mineral oil are mixed with a yellow - green, odorless powder.
Hydrazide foaming agent, toluene sulfonyl hydrazine (TSH) white crystalline powder, non-toxic, specific gravity 1.
Soluble in alkali, soluble in methanol, ethanol and butanone, soluble in water, aldehydes, insoluble in benzene, toluene.
Inorganic foaming agent 1.
Sodium bicarbonate sodium carbonate is an inorganic foaming agent, white powder, specific gravity 2.
Decomposition temperature of about 100-140 ℃, and release of CO2, lose all CO2 to 270 ℃.
Dissolve in water but not in alcohol.
(5) the more commonly used physical foaming agents have low boiling alkanes and fluorocarbon compounds.
Petroleum ether (naphtha)
