Silicone oil with hydrogen is all the rage! (III)
Polychlorophenylsilicone oil and branched phenylmethylsilicone oil for military use
Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, located in Lanzhou, northwest of China, has the third research lab specialized in the research of silicone oil and silicone grease with polychlorophenyltrichlorosilane as starting material for aviation industry and military industry departments. The lubricating oil, grease and working fluid for aviation industry based on methyl polychlorophenylsilicone oil developed by researchers such as jindawson, etc. The successful lubricants, greases and working fluids studied by them are produced by the chemical experiment plant and provided to the relevant departments. Many of the silicone products of the Institute have become the model matching products of many types of aircraft.
In the late 1960s, the country urgently needed all-weather sight hydraulic oil used in fighter. Through the Second Bureau of the Ministry of chemical industry, the office of national defense industry issued the task of urgent military scientific research, requiring Shanghai resin factory to provide a new type of silicone oil with very strict requirements for low temperature performance and viscosity temperature coefficient within three months. At that time, Zhang Jikai, who was assigned to the workshop as a worker, took on the task. After 81 days of tackling key problems, he and worker technician Xue Zhiqing and Workshop Engineer Xu Zhihong overcame many difficulties. At last, the branched phenyl methyl silicone oil was synthesized by the method of synthesis and additives, which has excellent low temperature performance and viscosity temperature coefficient change in line with the requirements. In advance, the company produced 80kg of new-type benzene methyl silicone oil with all technical indicators in full compliance with the requirements, and timely guaranteed the demand of fighter for flight to the sky, which was praised by the national defense industry office.
