用715快速激光粒度仪测定粒度分布西德《Aufbereitungs-Technik》1981年第4期西德的科学仪器经销部销售一种激光粒度仪,它可在几分钟内测出悬浮液中颗粒的粒度分布,有利于质量控制。激光粒度仪运用光运动原理,在凝聚的光束中颗粒引起了折射现象,这种现象表现为原来光束范围之外的光,出现的折射环的直径与粒度成反比,氦、氖激光器的光束从盛有乳浊液或悬浮液状样品的槽中射出,射出来的光束
Particle size distribution measured by a 715 Rapid Laser Particle Sizer “Aufbereitungs-Technik” No 4/1919 1981 Scientific instrument distributor in West Germany sells a laser particle sizer that measures the particle size distribution of particles in suspension in minutes , Is conducive to quality control. The laser particle size analyzer uses the principle of light motion and the particles cause refraction in the condensed beam. This phenomenon appears as light outside the original beam range. The diameter of the refraction ring appears inversely proportional to the particle size. The helium and neon laser beams change from The light beam emitted and emitted from the tank filled with the emulsion or suspension sample
