Particle size Distribution. The range of particle sizes in the manufactured powder coating.
粉末涂料生产时的粒子尺寸范围。
In general, smaller grain size and greater angularity tend to increase the porosity while an increase in range of particle size tends to decrease porosity.
通常，颗粒越小曲率越大孔隙度越大，而当颗粒尺寸增大时孔隙度会减。
Chronic exposure to more than 65 micrograms per cubic meter of any type of particle in this size range may increase risk for health problems.
长期暴露在含有超过65微克每立方米的任何颗粒的空气中，都会增加健康隐患。
