| Abstract: | The scale inhibition of poly-aspartic acid is studied with a series of experiments in this paper. The influence of Ca2+ concentration, the lasted time, the temperature and pH on the scale inhibition is investigated by static scale experimental system. The infrared spectrum and TG experiment are employed in character the structure and the quality of PASP. The experiment in sub- cooled boiling equipment validates the scale inhibition of PASP. The research indicates that poly-aspartic acid can be used in water... |
