Description

Technical Field

[0001] The invention relates to the technical field of polymer material processing, in particular to polyetheretherketone polymer reaction equipment. Background Art

[0002] When polyetherketone is crystallized, since it is carried out in a mixture with a solvent such as diphenyl sulfone, the shape of the crystals and the size of the pores between the crystals greatly affect the refining time of polyetherketone.

[0003] The Chinese patent with publication number CN103113574B discloses a method for preparing a nanostructured polyetherketone crystal, wherein a polyetherketone crystal sample preparation device is used to prepare corresponding polyetherketone crystal samples at different temperatures and different constant temperature times, and then the samples are crushed into particles of a certain size using a special crushing device, and then placed in a flooding extractor, diphenyl sulfone is extracted with acetone, and fluoride salt is extracted with water. Finally, the refined polyetherketone material sheet is obtained by drying.

[0004] Although this application solves to some extent the problems in the background technology of long refining time, high energy consumption, excessive pure water consumption and wastewater generation, in this application, after the synthesized polyether ketone mixed product is released, it is directly moved to the material tableting plate for only one tableting, which is time-consuming. During the tableting process, the polyether ketone mixed product is unevenly stacked, and the artificial adjustment prolongs the flattening time of the polyether ketone mixed product, which increases the risk of diphenyl sulfone oxidation.
