Analysis of External Influence Factors and Hydration Reaction of Static Crushing Agent
-
摘要:
为探究影响爆破用静态破碎剂水化反应过程中膨胀压力与温度变化的外部因素，基于多水平正交实验进行静态破碎剂的配方优化设计，利用“外管法”测试静态破碎剂膨胀压力，使用温度计探针实时监测破碎剂水化反应温度。从不同水灰比、不同环境温度、不同拌合水温三个方面对静态破碎剂进行水化反应分析研究，结果表明：静态破碎剂反应的峰值温度随水灰比的增加而先增加后降低；随环境温度以及拌合水温的升高而升高，整体水化反应温度经历“平缓—急剧升温—快速降温”的过程；静态破碎剂在测试钢管中的峰值压力随水灰比增大而呈现先增大后减小的趋势，随环境温度升高而升高，但温度过高易导致破碎剂喷孔使膨胀压急剧降低直至失去膨胀力。适当提高拌合水温对静态破碎剂水化反应起促进作用，拌合水温不宜高于35 ℃。
Abstract:In order to explore the external factors affecting the expansion pressure and temperature changes during the hydration reaction of static crusher, the formula optimization design of static crusher was carried out based on multi−level orthogonal test, the expansion pressure of static crusher was tested by using the “outer tube method”, and the hydration reaction temperature of crusher was monitored in real time by thermometer probe. The results showed that the peak temperature of the static crusher increased first and then decreased with the increase of the water−cement ratio. With the increase of ambient temperature and mixing water temperature, the overall hydration reaction temperature undergo a process of “gentle−sharp heating−rapid cooling”. The peak pressure of static crusher in the test steel pipe increases first and then decreases with the increase of water−cement ratio, and increases with the increase of ambient temperature, but too high temperature can easily lead to the expansion pressure of the crusher nozzle to decrease sharply until it loses its expansion force. Appropriately increasing the mixing water temperature can promote the hydration reaction of the static crusher, and the mixing water temperature should not be higher than 35 ℃. increase the mixing water temperature on the static crusher hydration reaction to promote the role of mixing water temperature should not be higher than 35 ℃.
