Abstract:
     The invention deals with the detailed technological scheme and procedure for promoting the formation of stable colloid structure by using calcium naphthenate or calcium sulfonate, sulfonic acid and thiophosphoric acid as a dissolve-promoting dispersing agent of calcium carbonate which is the basic component in high alkaline process without using higher fatty alcohols. The content of calcium in the product is up to 9-10%. The total alkalinity is 240-280 mg KOH/g. The product has good fluidity with viscosity ranging from 130-150 centistokes at 100 deg.C (that of foreign like-product OLOA-219 is 170 ceutistokes.)
