一、研究内容由于解放后新中国工业建设上之需要,及科学技术工作者爱国之热诚,我国各研究机关及工厂中从事硫酸工业用钒接触剂之研究工作者甚多。①永利宁厂接触剂制造部门对钒接触剂之研究工作已历多年,其情况前已报导,②兹更将近来进展及所得结果,借此篇幅以供各方参考。我们最近之工作着重于解决工业制造中所遭遇之一些困难,在矽藻土精制操作过程中,胶质矽藻土大量悬浮洗液中不易沉降,冲洗困难,我们依据“等电点”(Isoeletricpoint)之原
I. Research As a result of the need for industrial construction in new China after liberation and the patriotic enthusiasm of scientists and technologists, there are many researchers engaged in vanadium contact agents for sulfuric acid industry in various research institutes and factories in China. ① The research department of the contact-making agent in Yongliingning Factory has been studying the vanadium contact agent for many years and its situation has been reported before. More recently, the progress and the results obtained are provided for reference by all parties. Our recent work focuses on solving some of the difficulties encountered in industrial manufacturing, diatomaceous earth refined in the process of operation, a large number of colloidal silica suspension lotion difficult to settle, washing difficult, we based on “Isoelectric point” (Isoelepoint ) Of the original
