钛白粉—丙烯酸烘干清漆体系润湿性能的研究

An Experimental Study on the Wetting Properties of the Baking Varnish Comprised of TiO_2-propenoic Acid

本文依据浸湿液体重量平方与时间的关系式,测定了在25℃时TiO_2-丙烯酸烘干清漆体系的前进接触角,并计算其粘附张力。实验结果表明,重量平方法能应用于TiO_2-闪烯酸树脂体系润湿性能的研究,具有线性好、重现性较高、数据处理快速简便等特点。

The advancing contact angles in the system ot Baking varnish comprised of Tjo2 ?propenoic acid are measured experimetally at 25癈 according to the time-dependence of weight square of the immersing liquid,and the adhesional tensions are evaluated. The results show that the weight square method has. the features of good linearity ,high reproducibi1ity,and easily processing of data,and thus can be used in the research of wetting properties of the studied.
