제목 Evaluation of Solid Surface Properties by Analysis of Liquid Penetration Rate into Powder Beds
초록 Evaluation of solid surface properties by analysis of liquid penetration rate into powder beds is very important for application of powder products. The penetration rate was related the surface property in powder beds. So, the contact angle values for several powders to analysis surface property of powder were obtained by Washbun equation and Wicking method. The surface free energy value γS was divided into the polar component, γSp, and the dispersion component, γSd. The inorganic powder such as calcite were used as test samples. The effect of particle size and the kinds of experimental liquid were obtained on penetration rate. It was confirmed that the surface free energy of grinding sample decreased than the classification sample.
