Application of laser particle size analyzer in alumina (2)

As the particle size of alumina decreases, the oxygen index increases rapidly. The added amount reduces the processing performance and mechanical strength of the polymer. As the added amount increases, indicators such as the elongation at break decrease sharply. Therefore, ultra-fine particle size is pursued one-sidedly. It is also undesirable. In order to improve the processing performance, density and use performance of the final product of the polymer, attention should also be paid to the gradation of the particles and the shape of the particles to be controlled to make the particle size as small as possible under a large filling amount. Therefore, controlling product particle size is of great significance to improving various aspects of properties, and particle size testing becomes particularly important.

For testing the particle size of alumina powder, we recommend the Winner2308 fully automatic laser particle size analyzer. Alumina powder is generally in the range of several microns. The 2308 test range is 0.01-2000 microns. The helium-neon laser has better stability and one-click Operation, automatic centering, built-in dispersion, integrated control and good coordination. It adopts the unconstrained free fitting technology independently developed by Winner to truly reflect the particle distribution state. It is a powerful assistant for alumina powder particle size testing.
