磷化钙

薰蒸剂磷化钙成分的研究

Study of components in calcium phosphide as a fumigant

本文探讨了还原脱磷的基本原理，在特定的条件下钙与磷生成磷化钙的脱磷反应；

The basic principles of dephosphorization under reducing atmosphere are discussed .

钙改良的低温低锌磷化，钙的加入有利于镀锌板、铝板、钢板的复合件的磷化，可用于电泳涂装；

The second one is calcium modified low temperature and low zinc phosphating process , which is particularly useful for the phosphatization of the complex of galvanized , aluminum and steel plates in cathode electrocoating due to the addition of calcium .

锌钙系磷化膜层中钙的分光光度法分析

Spectrophotometric Analysis of Calcium in the Phosphate Film

为改善环保，选用污染小的促进剂A和B，研制出环保型单组分低温磷化液，包括锌锰系彩膜磷化液和锌钙系灰膜磷化液。

In order to improve environmental protection , accelerant A and B were adopted with little environmental pollution , environmental protective monocomponent phosphating solutions at low temperature were advanced which include zinc-manganese type color film phosphating solution and zinc-calcium type grey film phosphating solution .
