Abstract
(EN)
A functional polyester production system, which relates to the technical field of polymer material synthesis. The functional polyester production system comprises a polyester main body production system and a functional powder slurry concentrate preparation system; the polyester main body production system comprises an esterification system, a pre-polycondensation system and a final polycondensation system that are connected in sequence; the functional powder slurry concentrate preparation system comprises an online addition device that is connected to the esterification system or/and to a site between the esterification system and the pre-polycondensation system. By introducing a functional powder slurry concentrate preparation system into a polyester main body production system, a functional powder slurry concentrate having a low hydroxyl value and low pressure filtration value may be continuously prepared, and the prepared functional powder slurry concentrate and a polyester oligomer are uniformly mixed and then undergo a polycondensation reaction to obtain functional polyester in which functional powder is highly uniformly dispersed. The present invention also relates to a functional polyester production method.

L'invention concerne un système de production de polyester fonctionnel, se rapportant au domaine technique de la synthèse de matériaux polymères. Le système de production de polyester fonctionnel comprend un système de production de corps principal en polyester et un système de préparation de concentré de bouillie de poudre fonctionnelle ; le système de production de corps principal en polyester comprend un système d'estérification, un système de pré-polycondensation et un système de polycondensation finale qui sont raccordés dans l'ordre ; le système de préparation de concentré de bouillie de poudre fonctionnelle comprend un dispositif d'ajout en ligne qui est raccordé au système d'estérification et/ou en un endroit entre le système d'estérification et le système de pré-polycondensation. Par introduction d'un système de préparation de concentré de bouillie de poudre fonctionnelle dans un système de production de corps principal en polyester, un concentré de bouillie de poudre fonctionnelle ayant un faible indice d'hydroxyle et une valeur de filtration à basse pression peut être préparé en continu et le concentré de bouillie de poudre fonctionnelle préparé et un oligomère de polyester sont mélangés de manière homogène et subissent ensuite une réaction de polycondensation pour obtenir un polyester fonctionnel dans lequel la poudre fonctionnelle est dispersée de manière hautement homogène. La présente invention concerne également un procédé de production de polyester fonctionnel.
