火箭推进剂防护材料研究

Study on Protection Materials Against Rocket Propellant

火箭推进剂由于其特殊作用、使用条件和安全要求,需采用多种防护手段对其防护,尤其是防止对人体呼吸器官的损伤。研究了推进剂防护材料和装填方法,结果表明新研制的催化剂对氮氧化物和偏二甲肼均有较好的防护性能。在氮氧化物质量浓度为3.76mg/L时,防护时间>130min;在偏二甲肼质量浓度为4.55mg/L时,防护时间>160min。

Owing to peculiar function, working condition and safety requirement of rocket propellants, multiform protection means are necessary against them, especially preventing respiration organs of human body from hurting. The protection materials against propellants and fill pattern were researched. The results show that newly-prepared catalyst has a considerable protection property against oxides of nitrogen and unsymmetrical dimethyl hydrazine. The protection time is above 130min under the condition of 3.76 mg/L mass concentration of oxides of nitrogen; and the protection time is above 160min under the condition of 4.55mg/L mass concentration of unsymmetrical dimethyl hydrazine.
