Particle testing is a common technology, which involves the various sectors of the national economy powder industry, such as coatings, dyes, catalysts, cement, ceramics, refractories, sediment, dust, pesticides, fertilizers, private chat, drugs, food, seasoning Battery, detergent, pulp, rubber, plastic, cosmetics, toothpaste, nano-powder, antibacterial agent, gunpowder and so on.
 
What points of measuring neodymium iron boron particle size distribution by laser particle size analyzer is?
 
Nd2Fe14B is strong magnetic particles, generally use the ventilation method to measure the average diameter, by now it’s mainly use dry laser particle size analyzer to measure particle size distribution. Nd2Fe14B powder is with the characteristics of spontaneous combustion in the air, The ambient temperature is slightly higher or its concentration to a certain extent, spontaneous combustion,often ignite the vacuum cleaner pipe and filter and burn the vacuum cleaner. 
 
The methods of preventing spontaneous combustion: 
(1)High pressure nitrogen and other inert gas as the gas source; 
(2)Change the tube into the polyethylene pipe with a smooth surface,prevent the particles precipitating in the pipeline;
(3)A vacuum cleaner with water filtration
