Description
一 技术领域A technical field
本发明涉及一种单质炸药表面处理方法，特别是一种单质炸药降静电处理方法。The invention relates to a method for treating the surface of simple explosives, in particular to a method for treating static electricity of simple explosives.
二 背景技术Two background technology
单质炸药以其特有作功能力和猛度，广泛应用于军民领域。但是，炸药又是一类不导电物质，电阻率范围在4×1010～5×1012Ω·cm，因而在运动摩擦过程中易产生静电和积累静电，尤其在其干燥、筛选和包装工序，其静电电压可高达5～6万伏，而静电放电火花将会引起炸药的燃烧和爆炸，显然这是重大恶性事故的隐患之一，是潜在的危险因素。同时，单质炸药中存在有一定量的粉尘，致使颗粒间阻力增大，外界的机械挤压、摩擦、碰撞作用很容易引发爆炸反应。历年来由这类危害而导致爆破器材厂的技安事故屡见不鲜。因此，消除静电危害和改善药剂表面性能的措施是当前一项刻不容缓的重要课题。Elemental explosives are widely used in military and civilian fields due to their unique working ability and violent force. However, explosives are also a kind of non-conductive substance, and the resistivity ranges from 4×10 10 to 5×10 12 Ω·cm, so it is easy to generate and accumulate static electricity in the process of moving friction, especially in its drying, screening and packaging processes. , its electrostatic voltage can be as high as 50,000 to 60,000 volts, and electrostatic discharge sparks will cause the combustion and explosion of explosives, which is obviously one of the hidden dangers of major vicious accidents and is a potential risk factor. At the same time, there is a certain amount of dust in the elemental explosive, which increases the resistance between particles, and the external mechanical extrusion, friction, and collision can easily trigger an explosive reaction. It is not uncommon for technical safety accidents in blasting equipment factories to be caused by such hazards over the years. Therefore, measures to eliminate electrostatic hazards and improve the surface properties of pharmaceuticals are an urgent and important issue at present.
三 发明内容Three invention content
本发明的目的在于提供一种能显著降低炸药的静电积累，提高炸药流散性及稳定性以及安全性的单质炸药降静电处理方法。The object of the present invention is to provide a single-substance explosive static reduction treatment method that can significantly reduce the static electricity accumulation of the explosive, improve the fluidity, stability and safety of the explosive.
实现本发明目的的技术解决方案为：一种单质炸药降静电处理方法，其步骤是：将溶剂与抗静电剂混合形成稀溶液，并将此溶液加入到单质炸药中，单质炸药在溶液中经历悬浮浸润过程，达到充分浸润吸附后，经抽滤除去多余溶液，形成的湿态炸药经干燥即得在颗粒表面具有包覆层的抗静电炸药。The technical solution to realize the object of the present invention is: a method for treating single-substance explosives to reduce static electricity. Suspension infiltration process, after sufficient infiltration and adsorption, the excess solution is removed by suction filtration, and the formed wet explosive is dried to obtain an antistatic explosive with a coating layer on the particle surface.
本发明利用静电剂所含基团的自身离子化传导表面电荷，来降低处理后炸药的表面电阻和体积电阻，并适度增加导电性，从而防止静电积累而发挥抗静电效能；同时，依靠吸附包覆和团聚作用，能促使微小颗粒间的相互团聚而减少药剂微粉度。选用的抗静电剂是外部型抗静电剂BKD、HKD和HZ-1，一般用水或乙醇作溶剂配成3‰～5‰的溶液，按液料质量比1～2.5∶1的量，利用炸药制备工艺中的抽滤器，对炸药进行浸润，温度为室温，浸润时间为10min～15min。随后真空抽滤，并干燥脱离除去溶剂，干燥条件：真空度0.06MPa以上、柜温50℃～70℃、时间5h～9h。The present invention uses the self-ionization conduction surface charge of the group contained in the electrostatic agent to reduce the surface resistance and volume resistance of the treated explosive, and moderately increase the conductivity, thereby preventing the accumulation of static electricity and exerting antistatic performance; at the same time, relying on the adsorption package Coating and agglomeration can promote the mutual agglomeration of tiny particles and reduce the fineness of the medicine. The selected antistatic agents are external antistatic agents BKD, HKD and HZ-1. Generally, water or ethanol is used as a solvent to make a solution of 3‰～5‰. The mass ratio of liquid to material is 1～2.5:1. The suction filter in the preparation process soaks the explosive, the temperature is room temperature, and the soaking time is 10 minutes to 15 minutes. Then vacuum filter, and dry to remove the solvent, drying conditions: vacuum degree above 0.06MPa, cabinet temperature 50°C-70°C, time 5h-9h.
本发明与现有技术相比，其显著优点是：静电积累显著降低，流散性提高，有助于提高炸药抵抗外界危害的能力，保证产品质量和提高生产效率，在导爆索的生产中，可克服装药的不稳定性，避免以往时常发生的断药、少药、下药难等问题；而在雷管的生产中，能消除浮药和保证定容装药精度。Compared with the prior art, the present invention has the remarkable advantages of significantly reducing the accumulation of static electricity, improving the fluidity, helping to improve the ability of explosives to resist external hazards, ensuring product quality and improving production efficiency. In the production of detonating cords, It can overcome the instability of the drug, and avoid the problems of broken drug, less drug, and difficulty in dispensing that often occurred in the past; and in the production of detonators, it can eliminate floating drug and ensure the accuracy of constant volume charging.
典型处理样品的性能改善实测值列于下表：Measured performance improvements for typical treated samples are listed in the table below:
经表面处理后，太安的静电积累下降了83％，流散性则有所提高。其它的理化性能均符合GJB552-88《太安》的要求。经拉制导爆索和装配工程雷管，产品性能分别符合GB9786-88《普通导爆索》和GB13230-91《工业火雷管》标准。After surface treatment, Taian's static electricity accumulation decreased by 83%, and its fluidity improved. Other physical and chemical properties meet the requirements of GJB552-88 "Tai'an". The performance of the drawn detonating cord and assembly engineering detonator complies with the standards of GB9786-88 "Ordinary Detonating Cord" and GB13230-91 "Industrial Fire Detonator" respectively.
