| Abstract: | The technology conditions of polyethylene glycol wet activation treatment of heavy calcium carbonate powder were investigated by single-factor test method.The activation temperature,activation time,activator content on the influence of settlement volume was emphasized.Through the orthogonal experiment,the process conditions was optimized for the heavy calcium carbonate powder activation treatment:activation temperature 70℃,activation time for 43min,activator dosage for 1.6mg/g heavy calcium carbonate powder.Under these conditions,the settlement volume of heavy calcium carbonate powder was 0.78mL/g,viscosity was 140mPa·s,activation degrees was 90.0%,oil absorption degrees was 0.22mL/g,pH was 8.99. |
