- Abstract
Amino acid modified polyaspartic acids were evaluated as calcium‐scale inhibitors. Feasibility of scale inhibition experiments was analyzed by molecular dynamics simulation and Gaussian optimization, and the scale inhibition mechanism was theoretically analyzed. Scale inhibition performance was studied by scanning electron microscopy, X‐ray diffraction, X‐ray photoelectron spectroscopy, static scale inhibition experiments, and electrochemical performance testing, which provided an experimental basis for the molecular dynamics simulation. The experimental results showed that Arg‐SA‐PASP has better scale inhibition and corrosion inhibition performance than His‐SA‐PASP. The scale inhibition effect increased with increasing concentration. Electrochemical tests indicated that Arg‐SA‐PASP is an excellent scale and corrosion inhibitor.
