摘要
利用化学刻蚀加氟化的方法,在铝材表面制备具有疏水性能的纳米"乳突"的构造,防止含尘气流中的固体颗粒物在壁面的粘结,而使其易于清除。研究结果表明:氢氧化钠溶液浓度为10mol/L,氢氧化钠溶液刻蚀时间为10min,盐酸浓度4mol/L,盐酸刻蚀时间为7min的工艺条件下,对水的静态接触角为156°,具有较好的疏水性能。
By using chemical etching and fluori^ation, we have made nano ＂papillae＂ construct on the aluminum surface with a hydrophobic properties which can prevent on the bonding wall from solid dust particles in the gas stream so that the wall can be cleaned more easily. The results show that when using the 10mol/L of NaOH solution to etch for 10min and the 4mol/L of HC1 solution to etch for 7min, the static contact angle between the material surface and water reached a maximum of 158 °.Therefore, It is of hydrophobic properties.
