FIELD: metallurgy. ^ SUBSTANCE: composition contains, wt %: poly-acryl-amide-gel 0.01-0.02, modified bentonite with contents of montmoryllonite 80 % and over 0.1-0.5 and water - the rest. The procedure for production of inhibitor consists in introducing solution of water suspension of modified bentonite of concentration 2-20 wt % into concentrated water solution of poly-acryl-gel of 0.6-2.5 concentration at operating mixer and at rate of supply not more, than 2 l/min. Calculated amount of water is added into produced mass and is mixed during 3-5 min. If necessary, in field conditions water can be added directly before inhibitor usage. Insignificant concentrations of general access non-toxic components are present in the composition. The finished product is referred to low-hazard bio-de-composed substances. ^ EFFECT: high protective properties of steel items from corrosion. ^ 2 cl, 1 tbl |
