山东大学化学系胶体化学组的十九名应届毕业生,以改进活性白土质量为毕业论文的题目。他们兵分两路,在抚顺某工厂和学校实验室内进行实验。在六个多月的实验过程中,他们以毛泽东思想为指针,突破了思想、技术和设备上的重重障碍,终于试制成功了几种活性白土新产品,经过初步鉴定,在脱色能力上赶上和超过了国外某些产品。提高活性白土质量是一项有重要意义的研究课题白土,俗称观音土,是一种粘土矿物。经过化学
Shandong University Department of Chemistry colloidal chemistry group of 19 graduates to improve the quality of activated clay for the thesis topic. They split up in two divisions and conducted experiments in a factory and a school laboratory in Fushun. In the experiment of more than six months, they took the thought of Mao Zedong Thought as a guideline and broke through the obstacles in thought, technology and equipment. Finally, they succeeded in trial production of several new products of activated clay. After preliminary identification, they caught up with the decolorization ability And over some foreign products. To improve the quality of activated clay is an important research topic White clay, commonly known as Guanyin, is a clay mineral. After chemistry
