乳化炸药复合蜡含油量测定方法分析
|
摘要
含油量对乳化炸药复合蜡的强度、硬度、柔软性、滴熔点等物理性质有很大影响,从而影响乳化炸药的流动性及储存性能。蜡类含油量测定有丁酮-甲苯法(石化行业标准)与丁酮法(国家标准)。采用这2种方法对样品蜡含油量进行测定和分析,结果表明,不同方法的测定结果差别大,测定乳化炸药复合蜡含油量推荐采用丁酮-甲苯法,丁酮-甲苯作溶剂的NB/SH/T 0556—2010《石油蜡溶剂抽出物测定法》是最适宜的乳化炸药复合蜡含油量测定方法。
Oil content poses a great influence on strength,hardness,softness,drop point and other physical properties of the composite wax of emulsion explosive,thus to affect fluidity and storage performance of emulsion explosives.Two methods,butanone-toluene method( petrochemical industry standard) or butanone method( national standard),were used to determine and analyze the oil content of wax samples. The results show major inconsistence between the two methods. NB/SH/T 0556—2010 petroleum wax solvent extract method,in which butanone-toluene is used as solvent,is the superior method for the determination of oil content in compound wax of emulsion explosive and is recommended to test oil content in compound wax of emulsion explosive oil.
