摘要
将有机玻璃颗粒分散在水溶液中,通入不同功率、不同作用时间的超声波处理,观察超声凝聚作用和空化效应,测量水中粒子团的直径,分析超声波对颗粒凝聚的影响。结果发现,在超声波功率为45 W时,超声波的凝聚作用较好,凝聚效果随时间增加而增加;在超声波的作用时间为2 min时,超声波的凝聚效果明显,随着功率的增加,凝聚效果越好。选择合适的超声波功率及合理的超声波处理时间可以起到更好的处理效果。
At present, the method of using ultrasound to remove inclusion from liquid steel has increasingly been valued by people. To explore the mechanism of impurity removal with ultrasonic and obtain the reasonable conditions of ultrasonic impaction is of great academic significance and economic value. The Plexiglas＇s particle will be dispersed in aqueous solution, through ultrasonic treatment with different power and different times. Observing ultrasound cohesion and cavitations effect and measuring the diameter of water particle group as well as analysing the impact of ultrasound on particle cohesion, at the 45 w power of ultrasound, the cohesion of ultrasound is better and cohesion effect increased with the increasing of time. With the time of 2 min, the cohesion effect of ultrasonic is obviously getting better with the increase in power. Choose a suitable ultrasonic power and reasonable processing time can play a better effect.
