Abstract

A thermodynamic estimation of the Rebinder effect is analytically constructed upon adsorption of sulfonol from an aqueous solution on a flat surface of limestone. For the constructed function for evaluating the effect (increment of surface tension), conditions for its dome-shaped shape are obtained depending on the volume concentration of sulfonol. Comparison of the experimental curve of the surface hardness of limestone with the function of thermodynamic assessment of the Rebinder effect shows their behavior over the entire range of volume concentration values up to the concentration segment with a dense adsorption layer of a surfactant to be symbiotic. For the subsequent concentration range, a mechanism is proposed that explains the difference between theory and experiment.

粘合剂对石灰石吸附磺酚效果的热力学评价功能的构建

摘要

通过从水溶液在石灰石的平坦表面上吸附磺酚来分析地构造Rebinder效应的热力学估计。对于评价效果(表面张力的增加)的所构建的功能,根据磺酚的体积浓度获得其圆顶状的条件。石灰石表面硬度的实验曲线与Rebinder效应的热力学评估函数的比较表明,它们在整个体积浓度值范围内,直到具有致密的表面活性剂共生吸附层的浓度段为止,都具有行为。对于随后的浓度范围,提出了一种解释理论与实验之间差异的机理。
