Description
技术领域：Technical field:

背景技术：Background technique:
液晶聚酯料粒熔融态时一般呈现液晶性。这类材料具有优异的耐热性能和成型加工性能。聚合方法以熔融缩聚为主，全芳香族LCP多辅以固相缩聚以制得高分子量产品。非全芳香族LCP塑胶原料常采用一步或二步熔融聚合制取产品。连续熔融缩聚制取高分子量LCP的技术得到发展。拉伸强度和弯曲模量可超过发展起来的各种热塑性工程塑料。机械性能、尺寸稳定性、光学性能、电性能、耐化学药品性、阻燃性、加工性良好，耐热性好，热膨胀系数较低。Liquid crystal polyester pellets generally exhibit liquid crystallinity in molten state. These materials have excellent heat resistance and formability. The polymerization method is mainly based on melt polycondensation, and all-aromatic LCP is mostly supplemented by solid-state polycondensation to obtain high molecular weight products. Non-fully aromatic LCP plastic raw materials are often produced by one-step or two-step melt polymerization. The technology of producing high molecular weight LCP by continuous melt polycondensation has been developed. The tensile strength and flexural modulus can exceed that of various thermoplastic engineering plastics developed. Mechanical properties, dimensional stability, optical properties, electrical properties, chemical resistance, flame retardancy, good processability, good heat resistance, and low thermal expansion coefficient.
热致性液晶聚酯的加工过程一般是熔融共聚，然后进行切粒，切粒后需要将不符合颗粒尺寸要求的料粒筛分去除，提高产品合格率，由于切粒后直接进行筛分的过程中，料粒没有经过充分冷却，容易造成粘连，使得产品合格率降低。The processing process of thermotropic liquid crystal polyester is generally melt copolymerization, and then pelletizing. After pelletizing, it is necessary to sieve and remove the particles that do not meet the particle size requirements to improve the product qualification rate. During the process, if the pellets are not sufficiently cooled, it is easy to cause adhesion, which reduces the qualified rate of the product.
为了解决上述问题，中国专利CN201320655181.2提出了一种电缆料粒生产用风冷式电磁振动筛，该专利采用设置鼓风机给电缆料粒降温，避免电缆料粒发生“粘粒”现象，但是鼓风机的设置，导致料粒之间在风力的作用下发生聚团现象，更不利于其分散，粘连现象并没有得到有效解决。In order to solve the above problems, Chinese patent CN201320655181.2 proposes an air-cooled electromagnetic vibrating screen for the production of cable material particles. The setting of the material leads to the agglomeration phenomenon between the material particles under the action of the wind force, which is not conducive to its dispersion, and the adhesion phenomenon has not been effectively solved.
