| 摘 要： | 采用氧化镁压痕法,以铁红防锈漆为工质,研究了高压无气喷涂中喷嘴等效孔径、雾化压力等工作参数对涂料雾化效果的影响规律。对不同等效孔径的喷嘴在不同喷涂压力下的涂料雾化特性进行了实验研究,结果表明:涂料雾化颗粒的索特平均直径(SMD)和特征直径随雾化压力增大而减小,随喷嘴孔径增大而增大;雾化压力对雾化颗粒的相对尺寸范围影响较大,压力增大,雾化颗粒相对尺寸范围减小,雾化颗粒分布更均匀。

| Abstract: | The influence laws of high-pressure airless spraying working parameters such as equivalent diameter of nozzle and spray pressure on atomizing characteristics of paint had been studied with magnesium oxide indentation method and iron red antirust paint as working fluid.The experiments had been conducted on different nozzles with different equivalent diameter and different spray pressure.Experimental results show that the Sauter mean diameter and characteristic diameter decrease with the increases of the spray pressure,and increase with the increases of the equivalent diameter of nozzle.The relative size range is influenced greatly by the spray pressure,and it decreases with the increase of spray pressure,which makes the atomizing particle more uniform. |
