摘要
本文选取了十一种吸湿性物质,对它们的吸湿特性进行了实验研究, 对其中一些吸湿性能较好的催化剂开展了云室消雾试验。结果表明,这些物质的吸 湿能力及其随相对湿度变化的分布有较大区别,其他和状态下的平衡增长率也有 较大差异,水泥类物质中,矿渣水泥及普通425#K水泥的吸湿特性与氯化钠类似, 氯化钠、氯化铵及矿渣水泥的云室消雾效果较好,但其作用机理可能有所不同。
There are eleven hygroscopic agents selected in this paper and some experiment study on its specific property have been made. In cloud chamber,an artificial fog dissipation has been tried by method of seeding the catalytic agent of which hygroscopic capability is better. The results show that there are great differences in hygroscopic capability of the catalytic agents along with the alternation of the relative humidity and the equilibrium growth rates of radius of their condensation nucleus are different too. Among the all kinds of cement, only the slag cement and the ordinary 425# strength of cement have a similar characteristic of moisture absorption with the NaCl. It is very effective in artificial fog dissipation by seeding the NaCl and NH4Cl and slag cement and the role mechanism may be different.
