Preparation of a Room Temperature Emulsion Matrix with Vibration Resistancein Long-distance Transportation

介绍了一种耐振动、适宜远距离运输、现场装药车装药的乳化基质的研制。经检测,该乳化基质抗振动性好,在振动频率为1 Hz时,振动20 h后仍不破乳、不老化,敏化后爆速稳定;黏度适中,常温黏度为40 000 m Pa·s,不仅有利于现场装药车泵送,且耐储存,储存期达到30 d;敏化后爆速比普通混装乳化基质高,达到5 000 m/s以上;安全性好,摩擦感度和撞击感度均为0。可以满足长距离运输现场装药车装填的需要,适用于各类露天矿山远程配送装填使用。

A kind of shock-resistance mixed loading emulsion explosive favorable for long-distance transportation was developed. By examination, anti-vibration effect of this emulsion matrix is good. When the vibration frequency is 1Hz, neither demulsification noraging occurs after 20 h vibration. Its detonation velocity after sensitization is stable. The viscosity at room temperature is 40 000 mPa · s, which is not only beneficial to the charging pump, but also has a prolonged storage life of more than 30 days. The detonation velocity after sensitization is over 5 000 m/s, which is higher than that of common mixed loading emulsion matrix. Safety is ensured by the fact that both friction sensitivity and impact sensitivity are 0. It could satisfy the need of long-distance transportation packing, and be suitable for remote distribution in all kinds of open mining loading.
