FR型专用复合蜡在粉状乳化炸药中的应用?

以含蜡馏分油为原料,添加FR专用乳化剂和其他添加剂,利用均匀设计技术进行配方优化试验,着重考察复合蜡的滴点、黏度、含油量对粉状乳化炸药储存稳定性及抗水性的影响。试验结果表明,复合蜡适宜的滴点为70~85℃,适宜的黏度为75~85 mm2/s,适宜的含油量(质量分数)为20%~30%。通过工业应用试验结果表明,以FR型专用复合蜡为油相材料生产的粉状乳化炸药,爆炸性能满足WJ9025—2004岩石粉状乳化炸药标准的要求,可完全替代T-155、石蜡和微晶蜡等油相材料。

Application of FR Special Compound Wax in Preparation of Powdery Emulsion Explosive

Waxy distillate was used as the raw material of powdery emulsion explosive, in which FR emulsifying agent and other additives were added. Formula optimization test with uniform design technology was used to study the inf-luence of drop point, viscosity and oil content of composite wax on storage stability and water resistance of powdery emulsion explosive. Experimental results show that the best drop point of compound wax is 70-85 ℃, the most suitable viscosity is 75-85 mm2/ s, and the superior mass fraction of oil is 20%-30%. Experimental results show that, in industrial application, detonation properties of powdery emulsion explosive using FR special compound wax as oil phase materials meet the requirement of WJ9025—2004 standard Rock Powdery Emulsion Explosive. It could completely replace oil phase materials such as T-155, paraffin wax and microcrystalline wax.
