Title (EN) ALIPHATIC POLYESTER POWDER APPLICABLE FOR SELECTIVE LASER SINTERING, AND PREPARATION METHOD THEREOF
(FR) POUDRE DE POLYESTER ALIPHATIQUE APPLICABLE AU FRITTAGE LASER SÉLECTIF, ET SON PROCÉDÉ DE PRÉPARATION
(ZH) 一种适用于选择性激光烧结的脂肪族聚酯粉末及其制备方法
Abstract:
(EN) The present invention provides a preparation method of an aliphatic polyester resin powder. The crystalline aliphatic polyester resin powder obtained according to the present invention has superior oxidation resistance, superior powder flowability, a moderate size, a smooth surface, a proper bulk density, and a suitable dispersity and particle size distribution. The aliphatic polyester resin powder is particularly suitable for selective laser sintering.
(FR) La présente invention concerne un procédé de préparation d'une poudre de résine polyester aliphatique. La poudre de résine polyester aliphatique cristalline obtenue selon la présente invention a une résistance à l'oxydation supérieure, une coulabilité de poudre supérieure, une taille modérée, une surface lisse, une densité en vrac correcte, et une dispersité et distribution granulométrique convenables. La poudre de résine polyester aliphatique selon l'invention se prête particulièrement bien au frittage laser sélectif.
