The mechanism of the metallic Ca to influence the viscidity of molten aluminum and the infection of different quantity of metallic Ca to the porosity of closed-foam aluminum has been studied.
发现加入金属Ca并搅拌均匀后,主要生成金属间化合物CaAl4和CaAl2,在熔体中弥散存在,且CaAl4熔点(697℃)高于制备泡沫铝的试验温度(680℃),处于半熔化状态,因此增加了铝熔体粘度。
In order to study the rheological properties of three-phase foam,experiments were conducted to research the factors influencing its viscidity in relation to shear rate,expansion of foam,temperature and gaseous medium,and a rheological expression of three-phase foam is set up according to these parameters and its flowing resistance and reduction of pressure is measured in the pipeline.
为了研究三相泡沫的流体特性,采用实验的方法,考察了剪切速率、发泡倍数、温度、气体介质对三相泡沫粘度的影响,构建了三相泡沫流体的本构方程,测定了三相泡沫流体在注浆管路中的流动阻力及管压降。
According to the reflect characteristics of light and viscidity equation of Einstein,the influence of foil shape on the viscidity and luster of new metallic ink were studied.
根据光反射特点和爱因斯坦粘度方程,研究了颗粒形状与油墨的金属光泽和油墨粘度的关系,结果表明,长片状的金属颗粒能得到最好的印刷效果。
