Chromium hydroxide

The result indicates that adsorption of SLS on chromium hydroxide precipitate is physical adsorption .

结果表明，氢氧化铬沉淀主要是以物理吸附的形式吸附SLS。

Straw xanthate was prepared by using straw as raw material and taking effluent from chromium hydroxide reaction unit of metal chromium production as alkali source .

以稻草为原料，用金属铬工业生产中氢氧化铬反应工序排出的废液作碱源，制成稻草黄原酸酯，并用其处理模拟含铬废水和实际含铬废水。

When adding 0.3 % chromium hydroxide colloid into the samples and firing them at 1350 ℃, the apparent porosity decreased sharply from 1.33 % to 0.39 % .

1350℃烧成的试样引入0.3%氢氧化铬胶体时，显气孔率从1.33%迅速下降到0.39%。

The bath is liable to produce muddy chromium hydroxide precipitation without adequate ageing , and if the blank electrolysis is not conducted , the solution will be unstable , affecting the coating quality .

假使熟化不好，镀液容易生成泥浆状的氢氧化铬沉淀，若不进行空白电解则镀液不稳定，影响镀层质量。

But with the further increase of chromium hydroxide colloid addition , the excess colloid might lead to the agglomeration in the sample . The agglomeration separated from the ambient matrix by its sintering shrinkage , which resulted in the formation of big pore space and the decrease of strength .

但随着胶体加入量的增加，过多的胶体在试样中可能引起团聚，其烧结收缩与周围基体发生脱离，造成较大的孔洞，致使强度有所下降。
