Stearic acid mainly plays a waterproofing role in foam boards. Stearic acid can also be used as a waterproofing agent plus ammonia and industrial alkali. . It also has the effect of stabilizing foam!
Introduction to the properties of stearic acid
[English/Latin name]
[Overview]
English name: r - This strain is a solid fatty acid obtained from animal and vegetable oils and fats, mainly The ingredients are stearic acid (3) and palmitic acid (3).
Stearic acid
- Check the particle size
For water-soluble acid, take this product, heat it to melt, add an equal volume of freshly boiled hot water, shake for a few minutes, let cool, filter, and add to the filtrate Add methyl orange indicator droplets, which must not appear red. Take this product as a neutral fat or wax, add anhydrous sodium carbonate and water 3, boil to dissolve, the solution should be clear. Take this product from the ignition residue and inspect it in accordance with the law (Appendix VIII). Do not pass the remaining residue. Heavy metals: Take the residue left under the ignition residue category and check it according to the law (Appendix VIII, second method). The heavy metal content should not exceed 5 parts per million.

Stearic acid is widely used as a basic raw material for surfactants. At present, it is mainly used in the rubber industry as a vulcanization activator in the plastic industry. Used as a lubricant and stabilizer in the textile industry and household detergents, as a softener and bactericide in precision casting, as a wax mold in the grease industry, and as a soap base in the grease industry.
There are many production processes for stearic acid,
the main ones are: normal pressure catalytic hydrolysis, medium pressure catalytic hydrolysis, high pressure countercurrent hydrolysis, saponification hydrolysis, and enzymatic hydrolysis.
Among them, the one with better quality is high-pressure countercurrent hydrolysis. This production process has the best quality at home and abroad. The raw material for hydrolysis is the hydrolysis of fatty acid triesters - fatty acids and distilled fatty acids - the collected components - dusting (turning liquid stearic acid into solid stearic acid).
