FIELD: fluid medium purification, production of emulsified synthetic rubber. ^ SUBSTANCE: coagulant based on protein component contains as additional ingredients carboxymethyl cellulose, carbamide, alpha- and beta-amylase, fat aminoderivatives, carbamideformaldehyde resin and formalin in the next ratio (mass %): protein component 45.0-46.0; carboxymethyl cellulose 16.0-17.0; carbamide 10.1-10.2; alpha-amylase 9.4-0.5; beta-amylase 9.4-9.5; fat aminoderivatives 8.8-8.9; carbamideformaldehyde resin 0.03-0.04; and formalin 0.02-0.03. 50 % of aminoderivatives may be replaced with alkylbenzyldimethylammonium chlorides. As protein component preferably animal- or plant-origin protein is used. Coagulant is used in 3-8 % aqueous solution form, and consumption thereof in process of fluid medium purification is 0.1-1.0 mass % based on mass of isolating rubber. ^ EFFECT: stabilized coagulation process; reagent of increased coagulating action; isolated rubber of improved quality. |
