Application fields
Non-metallic powders: coarse whiting, light calcium, talcum powder, kaolin, graphite, wollastonite, brucite, barite, mica powder, bentonite, kieselguhr, clay, silicon dioxide, garnet, zirconium silicate, zirconium oxide, magnesium oxide, zinc oxide, etc.
Metal powders: aluminum powder, zinc powder, molybdenum powder, tungsten powder, magnesium powder, copper powder, rare earth metal power, alloyed powder, etc.
Other powders: lithium battery material, catalyst, fluorescent powder, cement, abrasive, medicine, agricultural chemical, food, coating, dye, river sediment, ceramic raw materials, chemical materials, nanometer materials, papermaking filler coating, all kinds of emulsions, etc.
Good repeatability
Reasons for good repeatability:
Laser, detector and signal transmission system stable and reliable.
Stable and effective dispersing system.
Automatic alignment system keeps the instrument always in optimum condition.
Sampling rate can reach 3500 times/second, and mass data can effectively reduce the influence of repeatability caused by little abnormal data.
