1983年初,航空工业部批准航空密封材料标准试验方法的十项新航标——HB5241～HB5250,其中七项为新方法,三项有较大改进。为保证今年七月实施新航标,根据部航标审定会及有关厂,所建议,于1983年6月10～20日由六二一所负责,三○一所、一二二厂大力支持,在哈尔滨举办了“航空密封材料标准试验技术培训交流会”.参加培训交流会的有各主机厂及部分辅机厂,空军修理厂,民航一○二厂、一○三厂,兵器工业部八○三厂,化工部沈阳油漆厂和黑龙江省化工研究所等共二十九个单位48人。参加人员以从事密封材料检验和应用的试验员、工艺员为主,也包括从事密封技术的工程师、技术员和军代表。我国航空密封材料研究、生产、使用已有二十多
In early 1983, the Ministry of Aeronautical Industry approved ten new aeroderivative marks - HB5241 ~ HB5250 - of the standard test methods for aviation sealing materials, of which seven were new and three were greatly improved. In order to ensure the implementation of the new beacon in July this year, according to the proposal of the beacon review meeting and the relevant factories, it was conducted by the June 21 to June 20, 1983, with 301 units and 122 plants vigorously supporting Harbin held a “training seminar on aviation seal material standard test technology.” Participated in the training exchange meetings with various OEMs and some auxiliary factory, Air Force repair shop, Civil Aviation Factory No.102, No.103 Factory, Ministry of Weaponry 803 plants, Shenyang Paint Factory Ministry of Chemical Industry and Heilongjiang Institute of Chemical Technology, a total of 29 units 48 people. Participants engaged in sealing material inspection and application of test workers, mainly craftsmen, but also engaged in sealing technology engineers, technicians and military representatives. China’s aviation sealing materials research, production, use more than twenty
