Preparation method of package static crushing agent
The invention discloses a preparation method of a package static crushing agent, and belongs to the technical field of performance optimization of crushing agents. According to the package static crushing agent, a non-woven fabric is used for manufacturing a cloth cylinder, the static crushing agent is contained in the cylinder, the optimal water absorption rate of the static crushing agent is theoretically calculated to be 26%, the non-woven fabric with the density being 40-50 g/m < 2 > is selected for manufacturing the cloth cylinder of the package static crushing agent through a non-woven fabric water absorption rate test, and the package crushing agent is soaked in water for 2-3 min before being used till no bubble is generated on the outer wall of the cloth cylinder and is plugged into a blast hole. The specification of the cloth cylinder is manufactured according to the actual hole diameter of a blast hole, the charge density is about 1.59 g/cm < 3 >, the expansion pressure of the packaged static crushing agent is improved by 16.7-20.1% compared with that of a bulk static crushing agent, operation and use are simpler, the stirring process is omitted, the possibility of hole spraying is reduced, and the problem that the bulk static crushing agent is difficult to use inclined holes, horizontal holes and upward holes is solved. After the reaction, the crushing agent is basically remained in the non-woven fabric barrel, so that the later cleaning work is more convenient, the engineering efficiency is effectively improved, and the harm of dust to a human body is reduced.
本发明公开一种卷装静态破碎剂的制备方法，属于破碎剂性能优化技术领域。所述卷装静态破碎剂利用无纺布制作布筒，筒内装入静态破碎剂，理论计算静态破碎剂的最佳吸水率为26%，经无纺布吸水率测试选择密度为40~50g/m2的无纺布制作卷装静态破碎剂的布筒，卷装破碎剂使用前浸水2~3min至布筒外壁无气泡产生塞入炮孔。布筒规格根据实际炮孔孔径大小制作，装药密度为1.59g/cm3左右，卷装静态破碎剂较散装静态破碎剂膨胀压力提高16.7~20.1%，操作使用更加简单，省略搅拌的过程，降低了喷孔的可能性，解决了散装静态破碎剂对斜向孔、水平孔以及上向孔使用困难的难题。反应后破碎剂基本存留在无纺布布筒内，后期清扫工作更加方便，有效提高工程效率，降低粉尘对人体的危害。
