【摘要】 本将通过微电子热天平测定钙矾石对水吸附的等温线，求出不同覆盖率时的吸附热及Freundlich等混吸附经验式=kPn中的经验常数n，并对吸附机理进行探讨，指出钙矾石对水的吸附存在配位场力，氢键力和毛细管凝聚力三种吸附力，揭示了钙矾石吸附术的现律，有助于对钙矾石稳定性的深入研究。更多还原

【Abstract】 In this paper. by dctcrmining the adsorption isothermal line of ettringite to water with themicroelectronic automatic hcat balance the adsorption hcats in diffcrent coverage surfaccs and the empirical constant in FreundIich adsorption isothcrmal empirical cquation F= kp’ are obtained,the adsorption mechanism is probed,the threee existing adsorption forces: Iigand ficId force hydrogen bond forceand capillary condensation force are given and the laws of adsorption water in ettringite are revealed.Thesc results will help the thorough study on ettringite stability.更多还原
