Information

Securities Times Network News On July 30th, Yahua Group completed the expert appraisal of the China Engineering Blasting Industry Association in the scientific and technological achievements declaration project "Yahua Digital Electronic Detonator Technology and Application" in Chengdu.

 

　　The well-known seven experts from the domestic civil explosion industry formed the appraisal committee. Wang Xuguang, academician of the Chinese Academy of Engineering, was appointed as the director of the appraisal committee. Zheng Wei, chairman of the Yahua Group, Gao Xin, president and vice president Liang Yuanqiang attended the appraisal meeting.

 

　　Yahua digital electronic detonator technology from the chip circuit design, packaging, production, testing and detonation system design are independent intellectual property rights, the use of integrated ignition components to replace the traditional hot bridge wire medicine, comprehensively and systematically enhance the digital electronic detonator technology Reliability. At the same time, the digital electronic detonator detonation system developed by Yahua has adopted the APP push detonation terminal mode to realize the rapid setting and optimization design of different delay schemes for engineering blasting.

 

　　The participating experts reviewed the relevant materials and listened to the report of the Yahua Group project team. After questioning and discussion, they fully affirmed the technical research and development achievements of the Yahua Digital Electronic Detonator in terms of quasi-explosiveness and ease of operation. Yahua Digital Electronic Detonator has made high praise for its high safety, high quasi-explosion rate, convenient operation and economic cost of blasting. It has sincerely praised the exploration and effectiveness of Accord to promote new products and technologies in the industry. Continued encouragement and unanimously believe that the technical development and application of the digital electronic detonator by Accord Blasting has a domestic leading level and reached the international level. (Source: China Blasting Network)
