设计了一种LZ复合表面改性剂,旨在抑制硫酸钙晶须的溶解,提高其留着率。考察了不同因素对硫酸钙晶须留着率的影响,得出了最佳改性条件,使晶须留着率由60.50%提高为93.67%。对改性前后硫酸钙晶须的表面性质进行IR表征及SEM观察,结果表明晶须表面发生了多层包覆与吸附,在此基础上建立了改性模型。
A kind of hybrid modify agent LZ was designed to inhibit the dissolution of calcium sulfate whisker(CSW) and improve its retention.Different modification conditions were studied to get an optimal method,by which the retention of CSW was improved from 60.50% to 93.67%.The surface properties changes before/after the modification were analyzed and characterized by IR and SEM.It was found that the CSW was coated and adsorbed multiply by the hybrid agents,and a modification model was set up.
