To obtain the required grinding of lime enriched with colloidal silver (specific surface area 5000-7000 cm2 / g or more), vibration mills should be used.

According to GOST 9179-77, residues on these screens are allowed up to 1 and 15%, respectively.

  • Silver provides oligodynamic (drying) effect of silver by disabling enzymes containing SH - and COOH - groups. Violation of one of these enzymes leads to the shutdown of the functions of the entire microbial and viral cell system. It is also assumed that one of the reasons for the wide antimicrobial effect of silver ions is the inhibition of the transmembrane transport of Na + and Ca ++ caused by silver.
