煤的表面疏水性与其组成之间的关系

Relationship between Surface Hydrophobicity and Composition of Coal

笔者引用相对原子数概念 ,对表征煤表面疏水性的接触角与煤的工业分析、元素分析结果之间的关系进行了分析探讨。用最小二乘法建立了接触角与煤炭组成关系的多元回归方程和一元的回归方程 ,对影响煤表面疏水性的因素进行了分析 。

Relationship between the surface hydrophobicity contact angle and proximate, ultimate analysis of coal was studied by using relative atomicity concept. The mono-regression equation and poly-regression equation between contact angle and composition of coal were established by using the method of least squares. The main factor to affect coal surface hydrophobicity is containing oxygen function groups in coal.
