FIELD: chemistry.
SUBSTANCE: agent against freezing and sticking in oil and dust-formation of moist granular materials, containing an alkaline runoff from caprolactam production and an additive in the form of glycerine. Also disclosed are versions of said agent, where the additives used are acetic acid and/or low-molecular weight acids from the wood chemical industry or glycerine and acetic acid and/or low-molecular weight acids from the wood chemical industry.
EFFECT: high effectiveness of the antifreeze agent owing to higher strength, flexibility and service life of films formed on metal surfaces, faster and higher degree of wetting carbon and high-strength hydrophobic materials while preserving quality factors of the antifreeze agent, such as low chilling point and homogeneity of the composition.
