in this paper, the influence of various parameters on suspension shearing dry strength and permeability of epc coating used on steel casting through right angle test was studied.
通过正交试验,研究了各因素对真空实型铸造铸钢件涂料的透气性、干强度、剪切力、悬浮性的影响。
wet breaking strength increased obviously after crosslinking, and the ratio of wet strength to dry strength increased by 16.9%, while there was a little impact on thermostability.
交联使纤维的湿断裂强度明显提高,湿干强度比可提高16.9%,但对纤维的热稳定性影响不大;
the dry strength agents have showed the obvious effect to increase the dry strength.
经过试验,发现该增强剂对纸的干强度有明显的效果。
it is common to use dry strength additive in paper plant. its action mechanism catch much attention all long, but it is not so clear as far as today.
meanwhile, the mechanism of dry strength additives is analyzed according to the theory of paper forming.
同时,结合纸页的成形原理,分析了增干强剂的增干强机理。
this structure and properties of the dry strength agents were characterized by the methods of ir, sem and so on.
并使用了ir、sem等手段对这种增强剂的结构和性能进行了表征。
the linear shrinkage and dry strength of green bodies decreases and the relative density increases with the increasing of solid volume loading.
随固相含量的增加,坯体的线收缩率和干燥强度下降,而坯体的相对密度不断增加;
it points out that the high pressure vacuum extruded forming process with selected glue can increase the dry strength of semi-product.
指出选用粘结剂,采用高压真空挤出成型工艺可提高半成品干燥强度;
guar gum derivatives are used as retention and drainage aids, as well as dry strength agent in the papermaking industry. the potential application in the future is pointed out.
