摘要

By controlling the concentration of NaOH in solution, the reaction mass ratio in the reaction between HA and NaOH, and the direct contact between the HA and NaOH solutions, various types of partially saponified HA were produced. Scale removal and scale prevention evaluations were performed according to the calcium scale precipitation method and the precipitation weight method. A scheme with optimal effects on scale removal and scale prevention integration was found, wherein the anti-calcium scale rate exceeded 80% and the calcium scale dissolution rate exceeded 70%. The influences brought on by the addition dosage of partially-saponified HA-U, duration of scale removal and scale prevention and temperature on the scale removal and scale prevention effects were investigated.
