Particle manufacturing equipment and application thereof

Abstract

The invention belongs to the field of micro-nano processing, and in particular relates to a particle manufacturing device and its application. The invention provides a particle manufacturing equipment, comprising: a laser, a reflector, a convex lens, a carrier and a receiver; after the laser generates laser light, the laser passes through the reflector and the convex lens in turn and reaches the carrier, After the sacrificial layer placed on the bearing member is acted on by the laser, an energy wave is generated, so that the liquid low surface energy material is sputtered to generate particles, and the generated particles reach the receiving member. The present invention also provides an application of the above particle manufacturing equipment in the preparation of low surface energy material particles. In the technical solution provided by the present invention, the types of raw materials are not limited, and particles of different sizes can be obtained by adjusting the laser to generate laser light with different energies, with high precision. The invention solves the technical defects of narrow particle preparation application range and poor particle size precision in the prior art.

Description

technical field [0001] The invention belongs to the field of micro-nano processing, and in particular relates to a particle manufacturing device and its application. Background technique [0002] Micronization preparation technology has a wide range of applications in the fields of powder combustion, spray drying, gas atomization, spray deposition, inkjet printing and rapid prototyping, and has extremely important significance in basic scientific research, such as fluid mechanics, flow mechanism etc. Micronization preparation technology is also widely used in aviation, metallurgy, electronic packaging, chemical industry, medicine and other industries, especially in the field of biological cell culture, because the characteristics of animal cell adherent growth require the carrier to have smooth surface and uniform size. Some biomaterials, such as PDMS (polydimethylsiloxane), have extremely low surface energies. It is difficult for liquid low surface energy materials to nat...
