Title: Innovations by Yihui Xu in Polyolefin and Polyester Resin Powders
Introduction
Yihui Xu, a notable inventor based in Beijing, China, has made significant contributions to the field of material science with a particular focus on resin powders. With a total of three patents to his name, Yihui's work prominently features advancements in selective laser sintering, a vital technique in manufacturing and 3D printing.
Latest Patents
Among Yihui Xu's latest innovations is a patent for a polyolefin resin powder suitable for selective laser sintering. This method for preparing the resin powder involves ensuring that the difference between the solubility parameters of the organic solvent and the polyolefin resin falls within a 0-20% range of the polyolefin resin's own solubility parameter. The resulting polyolefin resin powder exhibits excellent antioxidant properties, good powder flowability, moderate particle size, smooth surface texture, appropriate bulk density, and suitable dispersibility.
Another significant patent is for an aliphatic polyester resin powder, also designed for selective laser sintering. The preparation method includes several steps: heat dissolving a crystalline aliphatic polyester resin in an organic solvent, cooling to precipitate a solid, mixing optionally with an adjuvant, and finally conducting solid-liquid separation and drying. The crystalline aliphatic polyester resin powder produced by this method shares similar advantageous properties as the polyolefin variant, making it particularly suited for selective laser sintering applications.
