And the particle volume (V) relationship can be represented by an expression D = 1.24V1 / 3 Fig. In addition, particle size and particle size distribution data for a variety of different analytical methods may not be obtained confirm each other, can not be absolutely horizontal comparison. ? Since the particle size of the powder material is widely distributed, from nanometer to millimeter level, so when describing the material particle size, the particles can be divided according to the size of the nano-particles, ultrafine particles, particles, fine, coarse, etc. species. These particles may be based on the type of particle size analysis using the corresponding methods and instruments. One of the important indicators of recent years, with the rapid development of nanoscience and technology, particle size distribution and particle size nanomaterials characterization of nanomaterials has become, in the ordinary material particle size analysis, particle size of their research in general 100nm ~ 1um size range. Faced with nanomaterials research droplets angle outlets, scales the most attention. In real life, there are many areas such as energy, materials, pharmaceutical, chemical, metallurgy, electronics, machinery, light industry, construction and environmental protection are all closely related molecular materials with particle size. In polymer materials such as polyethylene resin is a multi-pores of the powdered substance droplets angle measuring instrument, not only by the nature and properties of the molecular characteristics (molecular weight, molecular weight distribution, a chain structure) on the angle of the water droplets, and the morphological and molecular characteristics (such as surface morphology of the particles, the average particle size, particle size distribution) has a close relationship. Polyethylene molecular and morphological features and products in turn determines the properties of the polymer during molding. Studies have shown that the form of the resin particles is good, moderate average particle size, particle size distribution in favor of a uniform polymer molding, so people often need to PVC resin particle size analysis tests. Nano-modified plastics additives in the sweet side, add nanomaterials as a filler in plastics plastics, not only can increase the mechanical strength of the plastic, airtight plastic can also increase the performance of gas and increased retardant properties. These reflect the performance of direct and shape, particle size and distribution and other factors add nanomaterials are closely related. Therefore, the need for characterization and analysis of these nano-particle additives. In terms of modern ceramic materials, functional ceramics composed of nanoparticles is an important research direction of the ceramic material. By using nano-functional ceramic material can significantly alter the physical and chemical properties of ceramics, such as toughness. Many important properties of ceramic powder materials by the average particle size and particle size distribution and other parameters of the decision. In the field of water droplets coated with a horn manufacturers, pigment particle size determines its coloring ability, particle size determines the film-forming additives strength and wear resistance. In the field of electronic materials, the phosphor particle determined display brightness and definition television, monitor, etc. of the screen. In the field of catalysts, the catalyst particle size, distribution and morphology also partly determine their catalytic activity. Thus, with the development of science and technology, about the particle size analysis technology has been widespread attention, has gradually developed into a measure of an important branch of science.
