我国目前橡胶制品年报废量达100万吨以上,积极发展回收废旧橡胶的胶粉生产势在必行。北京航空航天大学将航空高技术成功地运用于橡胶工业,采用空气涡轮的制冷工艺流程,用于制取精细橡胶粉,关键技术是低温冷源、粗胶粉冷冻系统及低温下细碎设备。其特点为:(1)技术路线先进,能替代液氨, At present, China’s annual scrap rubber products amounted to more than 1 million tons, and actively develop the recovery of waste rubber rubber powder production is imperative. Beijing University of Aeronautics and Astronautics successfully applied aviation high technology to the rubber industry. The air turbine cooling process was adopted to prepare fine rubber powder. The key technologies were cryogenic cold source, coarse rubber powder freezing system and fine crushing equipment at low temperature. Its characteristics are: (1) advanced technology route to replace liquid ammonia,
