发明名称 APPLICATION OF POLYETHYLENE IMINES AS ADDITIVE IN WATER SUSPENSIONS OF MATERIALS, INCLUDING CALCIUM CARBONATE
摘要 FIELD: chemistry.SUBSTANCE: polyethylene imine can be added to water suspension, which has pH between 8.5 and 11 and contains at least one material, including calcium carbonate, in amount from 25 to 62 vol% counted per the total volume of suspension, to increase suspension pH by at least 0.3 pH units. Change of suspension conductivity constitutes not more than 100 mcS/cm per pH unit. Polyethylene imine is added to said suspension in amount from 500 to 15000 mg per litre of water phase of said composition.EFFECT: invention makes it possible to increase stability of electric conductivity of calcium carbonate suspension.23 cl, 3 tbl, 1 ex
