用矿物质去除脱墨浆中微细胶粘物的可行性

Judgment of Microstickies Removability with Minerals during Paper Recycling

介绍了测定接触角的薄层吸液技术及应用接触角计算表面张力及Gibbs自由能变化的公式。最后以Gibbs自由能变化来判断某种矿物质对某些胶粘物有无粘附作用,从而选择何种矿物质可解决微细胶粘物的沉积问题。

Determination of contact angle with thin layer wicking technique and calculations of surface tension and Gibbs free energy change are introduced in this paper.According to the Gibbs free energy change,positive or negative,high or low,the micro stickies re-movalibility with some minerals can be judged.
