摘要
用微电子热天平测定了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等温吸附经验式Γ＝ｋｐｎ中的经验常数ｎ，并对吸附机理进行探讨。发现存在配位场力、氢键力和ＶａｎｄｅｒＷａａｌｓ力共三种吸附力。
The adsorption isotherm of water in ettringite were determined by use of automatic microelectron thermal-balance to obtain the adsorption heat for different coverages of surface and empirical constant n in Freundlich isotherm adsorption equationΓ =kpn and the adsorption mechanism was discussed. It was find that three adsorption force exist,i.e. ligand field force, hydrogen hond force, and Van der Waals force.
