摘要
为探究纳米流体的化学抑尘效果,利用2步法用粒径约为40 nm的氧化铜颗粒、二氧化硅纳米颗粒、2 mg/m L的氧化石墨烯溶液制备不同浓度的纳米流体进行抑尘性能测试。测试并分析所配制溶液的抗蒸发性、吸湿性和抗风蚀性等3种抑尘性能指标。结果表明:纳米流体的抗蒸发性能不明显,10%SiO2-水纳米流体有一定的抑尘效果;不同浓度纳米流体的吸湿率无较大差异,总体偏低;纳米流体的抗风蚀性能突出,风速越高,纳米流体的抗风蚀性能越显著。
In order to explore the chemical dust suppression effect of nanofluids,different concentrations of nanofluids were prepared by using'two-step method'including the particle size of about 40 nm of CuO particles,SiO2 nanoparticles and 2 mg/m L of oxidation graphene.The properties of anti-evaporation,moisture absorption and anti-wind erosion were studied experimentally.The results show that the anti-evaporation performance of nanofluids was not obvious,that 10%SiO2-water nano-fluid has a certain dust inhibition efficiency,that there is no significant difference in the moisture absorption rate of nano-fluid between different concentrations,and the rate is generally low,and that the nanofluids have outstanding anti-wind erosion performance,and the higher the wind speed is,the more significant the wind erosion resistance of nanofluids will be.
