FIELD: chemistry.
SUBSTANCE: to produce water suspension, reducing formation of deposits and/or corrosion, at least, one anionically-charged comb polymer is brought in contact with calcium carbonate-containing material and water. Obtained suspension contains solid phase from 45 to 82 wt % relative to the total weight of water suspension. Anionically-charged comb polymer is present in quantity from 0.01 to 10 wt % and has specific charge from -10 C/g to -250 C/g at pH = 8. Electric conductivity of suspension constitutes less than 500 mcS/cm at 25°C.
EFFECT: invention makes it possible to prevent formation of deposits from suspension on metal surfaces, as well as metal corrosion.
