检测方法
The following is a test method for the common properties of ash calcium powder:
Appearance: Using the visual method, observe the particle shape, color and other characteristics of gray calcium powder.
颜色: The use of color comparator or color meter and other instruments, based on international standard color cards or specific color indicators, to determine the color of gray calcium powder.
Particle size distribution: Using a laser particle size analyzer, the particle size distribution of gray calcium powder is determined by the relationship between the intensity of scattered light and particle size.
亮度: Use a gloss meter to measure the intensity of light reflected from the surface of the gray calcium powder to obtain its brightness value.
