化学发泡条件对乳化炸药性能的影响
Research on Impact Factors of Chemical Foaming of Emulsion Explosive

摘要:  
通过试验,对比不同敏化温度、水相pH值、发泡剂用量、促进剂选择与用量以及应该注意的关联因素等对乳化炸药的密度、储存期的影响。结果表明,每生产1 kg乳化炸药,NaNO2的加入量在1.1~1.5 g为宜。在要求的工艺条件下,适当加入46#机油既可增加乳化炸药产率,又不会影响储存期;控制在40~50℃的敏化温度可以满足生产、使用的要求;水相溶液pH值应控制在4.0~5.4之间;使用盐类与有机酸复合配置的促进剂,可以延长产品的储存期;选择适当的装药方式,可使炸药密度达到1.00~1.20g/cm3的理想值。
Abstract:?  
The effects of different sensitizing temperature,pH value of aqueous phase,blowing agent,accelerator selection and dosage period,as well as associated factors to the density and storage of emulsion explosives were examined. Results show that the best addition of NaNO2 was 1.1-1.2g to produce 1kg emulsion explosive.Under required process con-ditions,adding 46#oil could increase the yield of emulsion explosive without compromising the storage period.Sensitizing temperature at 40-50℃meets the production sensitization,use requirements.pH value of aqueous solutions should be con-trolled between 4.0 to 5.4;Through configuring compounds containing salts and an organic acid as accelerator,the storage period of the product can be extended;Selecting the appropriate charge way could make explosive density reach 1 .00-1 .20 g/cm3 .
