北京矿冶研究总院的四项科研成果,于1991年11月通过了有色总公司主持的技术鉴定。1KDW型抗严寒乳化炸药及RA型抗酸性水散装乳化炸药,是根据有色总公司下达的指示并针对苏方提出的特殊需求,采用苏联提供的部分原料而研制的。KDW型抗严寒乳化炸药在-45～-50℃的严寒条件下,冷冻2天后药体的不结冻、不导电,起爆可靠,自然存放6个月,其炸药爆速可达3600
Beijing Research Institute of Mining and Metallurgy four scientific research achievements, in November 1991 adopted the technical supervision of the colored head office. 1KDW anti-cold emulsion explosive and RA-type anti-acid water bulk emulsion explosive are developed based on the instructions issued by Nonferrous Corporation and in response to the special needs of the Soviet Union, using some of the raw materials provided by the Soviet Union. KDW-type anti-frost emulsion explosives in the -45 ~ -50 ℃ under the conditions of freezing, frozen body 2 days after the drug is not frozen, non-conductive, detonating reliable, natural storage for 6 months, the explosive detonation rate of up to 3600
