Description

Technical Field

[0001] The utility model relates to the technical field of PPS production equipment, in particular to a PPS thermal processing equipment. Background Art

[0002] PPS is a thermoplastic engineering plastic containing phenylthio groups on the main chain of the molecule, belonging to the polyether plastic. It was industrialized in the United States in 1968, and the main industrial production methods are solution polymerization and self-condensation. From the molecular structure of PPS, it can be seen that it is a linear or slightly branched polymer composed of alternating benzene rings and sulfur atoms. The molecular chain has strong integrity, and the main bond connected by the rigid benzene ring and the flexible sulfide chain has the characteristics of both rigidity and flexibility. Therefore, PPS can crystallize and has a high melting point; secondly, because the benzene ring and the sulfur atom form a conjugate. And the sulfur atom is not yet saturated, and after oxidation, the sulfide bond can be converted into a sulfoxide group, or adjacent macromolecules can be formed into oxygen bridge branching or cross-linking, so that the thermal and oxygen stability is very prominent; third, because the polarity of the sulfur atom is bound by the conjugation of the benzene ring and the high crystallinity, PPS presents non-polar or weak polar characteristics, so the electrical insulation, dielectric properties, and chemical resistance of PPS are also very prominent; fourth, because PPS has good compatibility with many polymers and additives, it can be modified by a variety of means to improve its mechanical properties and other properties. The PPS modified material needs to be heated during the production process, so that the PPS modified material can be better processed into plastic particles. The existing Chinese utility model patent, such as patent number CN216658985U, discloses a thermal processing equipment for PPS modified materials, and the heating of the PPS modified material in the thermal processing equipment is not uniform enough, and the heating efficiency is also relatively low.
