摘要
通过两步法制备了氮化硼/乙二醇(BN/EG)纳米流体,研究了超声振荡时间、pH值、分散剂种类及添加量3种因素对其稳定性的影响。结果表明超声分散时间太长或太短都不利于流体的稳定性,实验中取30min最好;酸或碱的加入都会使BN/EG纳米流体稳定性急剧恶化;适量分散剂PVP的加入能够明显改善BN/EG纳米流体的稳定性。
BN/EG nanofluid was synthesized by a two-step method.The influencing factors such as time of ultrasonic agitation,pH value and dispersant on stability was investigated.The experimental results indicate that the optimal ultrasonic agitation time is 30min in current experiment.The addition of acid or alkali will damage the stability of the nanofluids.Proper quantities of PVP can improve the stability of the nanofluids.
