free alternant

2 mm were compared using the Lipophilic Hydrophilic Ratio(LHR) concept which was defined on the basis of the Washburn equation, and their surface free energy components were also estimated using the Washburn equation and van Oss-Chaudhurry-Good(vCG) theory with n-hexane,α-bromonaphthalene, formamide and water as probe liquids.

2mm无烟煤、锰砂和石英砂滤料的润湿性;同时以正己烷、1-溴萘、甲酰胺和去离子水为探针液,用Washburn方程和vanOss-Chaudhurry-Good(vCG)理论对滤料表面自由能成分进行了估算。
