摘　　要：重点研究了几种不同的表面活性剂在硬质合金混合料表面的吸附行为。研究表明:表面活性剂在硬质合金粉末/正己烷体系中的吸附过程很快,且不同的表面活性剂对硬质合金粉末的吸附效果各有不同。初步研究了表面活性剂在不同的温度下对试验的影响。在这些表面活性剂中,表面吸附能力由大至小依次为油酸、硬脂酸、十六醇、甲基丙烯酸十八酯、十八胺,其中常温下油酸的最大吸附量为12.94×1019个/g。This paper studies the absorption properties of several different surfactants on cemented carbide powder surface. Preliminary research indicates that the absorption process of surfactant in cemented carbide powder hexane system is very quick and the absorption effects of different surfactants on cemented carbides powder are different. Adding different amounts of cemented carbide powder in the same solution have different effects. The effect of temperature on the absorption properties of surfactants was also studied. The results showed obviously the hierarchic order of the absorption capacity of the common surfactants listed as following, oleic acid, stearic acid, hexadecanol, octadecyl methacrylate and ODA. The absorption capacity of oleic acid is 12.94× 1019 ind/g in room temperature.
