标准范围

规定的方法反映了粉末喷涂的商业实践。其原理是在无气流条件下,将规定量的涂层粉末放入容器中,并在大气温度和压力的标准条件下,用清洁干燥的空气使其流态化。测量流态化期间和之后的粉末高度,然后确定流态化粉末流经指定孔口的速率。测量值用于计算流态化系数和粉末流量(流量系数),它们共同定义了粉末的输送和喷涂特性。

The method specified reflects commercial practice in powder spraying. Its principle is placing, under draught-free conditions, a specified quantity of coating powder in a vessel and fluidizing it with clean dry air under standard conditions of atmospheric temperature and pressure. The height of the powder during and after fluidization is measured and the rate at which the fluidized powder flows through a specified orifice is then determined. The measurements are used to calculate the fluidization factor and the powder flow rate (flow factor) which together define the transport and spraying characteristics of the powder.
