| 摘 要： | 考察了几种不同类型表面活性剂对一种气相白炭黑的分散效果。经比较研究发现：吐湿－80和六偏磷酸钠的分散效果较类似且较好，对此进行了讨论并选择六偏磷酸钠作为分散剂测试了由硅灰石制制得的多孔SiO2粉体的颗粒粒径。初步确定，该多孔SiO2粉体作为填料可用于反光塑料制品中。

| Abstract: | It is observed and studied the scrattering effect of some different kinds of surfactant on a kind of vapour phase silica white. Through contrustive study, the scattering effect of Tween 80 and calgon is better than others and similar. It is discussed that the particle diameter of porous silica powder made from wollastonite is measured through choosing the calgon as dispension agent. It is decided tentatively that the porous silica powder as filling can be used in the plastic product with reflecting light. |
