Detection method of white corundum particle size
There are many ways to detect the particle size of white corundum, and the detection methods are different for different particle sizes. The most commonly used methods are screening method, instrument tapping sieve, laser method, and European and American laser particle size analyzer.
1. Screening method.
2. Microscopy (image) method
3. Settlement method (including gravity settlement).
4. Resistance method.
5. Laser method.
6. Electron microscopy.
7. Photoresist method. Advantages: The test is convenient and fast, can measure the number of particles in liquid or gas, and has high resolution.
8. Breathability. Advantages: The instrument is low in price. No need to disperse the sample, material powder can be measured.
9. X-ray small angle scattering method. Used to measure the particle size of nanoscale particles.
10. Photon correlation spectroscopy (dynamic light scattering method). White corundum for particle size measurement of nanoscale particles.
