Abstract

The invention provides a preparation device and preparation technology for polymer-based spherical powder. The preparation device comprises a grinding disc grinding system and an inductive coupling plasma powder nodulizing system, and the grinding disc grinding system of the preparation device achieves material ultrafine grinding under the room temperature condition by exerting strong extruding stress, cutting stress and circumferential stress to materials; and the inductive coupling plasma powder nodulizing system takes high-temperature plasmas as a high-temperature heat source, polymer powder is heated uniformly, the melting and cooling rate is high, and nodulizing treatment can be completed in an ultrashort time. According to the preparation device, the preparation process of the polymer-based spherical powder is integrated and achieves continuous production, the preparation technology is significantly improved, therefore, the polymer-based spherical powder material which has the excellent performance and can be applied to the SLS field is prepared, and large-scale batch production can be achieved.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and in particular relates to a preparation device and a preparation process of a polymer-based spherical powder, which is especially suitable for the preparation of raw materials for selective laser sintering technology. Background technique

[0002] Selective laser sintering (SLS) technology is an important 3D printing technology, which is an advanced manufacturing method based on discrete / stacking principles that has developed rapidly in recent years. SLS technology uses the thermal effect of laser to selectively melt powder materials according to CAD model, and superimpose them layer by layer to form the final product. Compared with traditional processing methods, the technical advantages of SLS processing mainly lie in free forming and integral manufacturing, which can be used to produce parts with arbitrary complex structures, and realize the customized production of complex parts.
