“DJB—823”(以下简称“823”)保护剂是北京邮电学院彭道儒教授发明研制的,1986年荣获国家发明二等奖。金属表面经过“823”保护剂的涂覆后,具有防潮湿、抗盐雾、防止工业大气、手汗等各种腐蚀介质侵蚀的特点。金属刀具、刃具、模具在涂覆“823”保护剂之后,表面摩擦系数降低,润滑性能提高,明显延长了使用寿命。 “823”保护剂从发明到现在,已经过国家和军队10年的推广和应用。1991年12月国防科工委为这项技术成果制订了国家军用标准,其中10多项指标居世界领先 DJB-823 (hereinafter referred to as “823”) was invented and developed by Professor Peng Dao-ru from Beijing University of Posts and Telecommunications. In 1986, it won the second prize of national invention. Metal surface after “823” protective agent coating, with moisture, salt spray, to prevent the industrial atmosphere, hand sweat and other corrosive media erosion characteristics. Metal cutting tools, cutting tools, mold coating in the “823” protective agent, the surface friction coefficient decreased, improved lubrication performance, significantly prolongs the service life. “823” protective agent from the invention to the present, has been 10 years of national and military promotion and application. In December 1991, the Commission of Science, Technology and Industry for National Defense formulated the national military standard for this technical achievement, of which more than 10 indicators rank the world’s leading
