Description
Technical field
The utility model relates to a kind of polyester solid-phase tack producing serialization production equipment.
Background technology
Advantages such as polyester (PET) industry silk has the modulus height, elongation is little, boiling water shrinkage is low, heat-resisting and fatigue performance is good are the manufacturing tire cords, the ideal material of rubber item skeleton and various industrial spinning product.It processes raw material and is the section of PET tackify.The big polyester of this limiting viscosity height, molecular weight method in common in the world is to adopt process for solid state polycondensation, be that the polyester slice that molecular weight is lower is heated to more than the second-order transition temperature, be less than about under fusing point 20-40 ℃ the method that under vacuum or rare gas element, relative molecular weight is increased greatly through esterification or transesterification reaction solid phase polycondensation.The preparation method that industry silk level PET increases glutinous section mainly contains 4 kinds: direct polymerization method, the method for carrying out polycondensation again after catalyst method, process for solid state polycondensation and the fusion of will cutting into slices of adding.The process for solid state polycondensation production technique is low with its side reaction, product Heat stability is good, color and luster are good etc., and advantage develops into the main flow production technique.At present external solid phase polycondensation continuous device mainly contains U.S. Bepex company, Switzerland Buhler company, German Zimmer company etc.Though its device configurations, operating parameters but present rich diversity, the solid phase polycondensation process main process broadly similar of each company.Its solid phase polycondensation process main process generally is divided into pre-crystallization, drying, crystallization, preheating, solid phase polycondensation, cooling etc., and pairing equipment is pre-crystallizer, drying tower, crystallizer, preheater, solid state polycondensation device, water cooler.
In the solid state polycondensation process is to control degree of crystallinity, the water ratio of section, viscosity by heating, remove moisture content and lower-molecular substance.The effect of pre-crystallizer is in order to make section have higher crystallization velocity, and raising degree of crystallinity, when improving through the degree of crystallinity of cutting into slices behind the drying tower, surface-moisture is also removed effectively, further increase by the section degree of crystallinity that enters behind the crystallizer, water content descends significantly.The section of leaving behind the crystallizer is further heat-treated and crystallization in preheater, improves the temperature of section, for solid state polycondensation is prepared; Section has high-crystallinity, low-water-content through solid state polycondensation, and full-bodied characteristic is also finished whole solid state polycondensation process after cooling.At solid phase polycondensation, enterprise is mostly by transforming equipment of solid-state polycondensation and optimizing technology and finish both at home and abroad." the continous way solid phase polycondensation is produced the high sticking industry silk section pre-test of PET " (" polyester industrial ", 1999,12 (3): 25-33) in the solid phase polycondensation process of being introduced, pre-crystallizer, crystallizer are the moisture content that heats and remove section by air.Because airborne moisture content and other material have produced certain influence to section, and are substituted by nitrogen." technology and the technology of continous way solid phase polycondensation production polyester slice with high viscosity " (" synthetic fiber industry ", 1997,20 (5): what 53-55) introduce is to adopt the deep fat heating, and nitrogen is removed the moisture content of section." optimization of PET Solid-State Polycondensation Process " (" printing during chemical industry ", 2006,20 (10): 9-14) by increasing the effect that a crystallizer improves the section solid phase polycondensation again." PET solid phase polycondensation process technical Analysis " (" synthetic technology and application ", 2006,21 (1): 30-31) removed drying installation in the continous way solid phase polycondensation process flow process of the solid phase polycondensation process flow process of the Bepex company of Jie Shaoing and Buhler, shortened technical process.Will consume a large amount of energy in the solid state polycondensation process, though the improvement that above-mentioned technology has, technical process is still very complicated, and flow process is very long.Equipment is huge, and drying tower, preheater have in use consumed a large amount of energy, cuts into slices in addition and unavoidably bring dust in drying tower stop process, makes intrinsic viscosity inhomogeneous, brings for the section quality and has a strong impact on.
In order to reach purpose of energy saving, keep quality product, the purpose of this utility model is to provide a kind of used cost low, and side reaction is low, Heat stability is good, the high and high polyester solid-phase tack producing serialization production equipment of quality product of production efficiency.
Summary of the invention
The purpose of this utility model provides a kind of polyester solid-phase tack producing serialization production equipment, particularly providing a kind of is the continuous solid-phase tack producing device of flow process with pre-crystallizer, crystallizer, solid state polycondensation device, water cooler, conventional solid-phase tack producing device is economized except drying tower, preheater, simplify operational path, reached purpose of energy saving.
A kind of polyester solid-phase tack producing serialization production equipment of the present utility model, comprise that pre-crystallizer, crystallizer, solid state polycondensation device, water cooler are the continuous solid-phase tack producing device of flow process, more than device connects successively, raw material section e Foerderanlage is being arranged and increasing glutinous section e Foerderanlage before and after the solid-phase tack producing device continuously.
The utility model is achieved in that pre-crystallizer adopts the deep fat heating, and nitrogen is removed the moisture content of section, prolong simultaneously section time, the section temperature is 175 ± 5 ℃, the degree of crystallinity that makes section is greater than 40%, water content is less than 230ppm.Crystallizer also adopts the deep fat heating, and nitrogen is further removed the moisture content of section, increases the residence time of section, and the section temperature is 210 ± 10 ℃, and the degree of crystallinity that makes section is greater than 50%, and water content is less than 50ppm.The section temperature is 220 ± 10 ℃ in the solid state polycondensation device, increases the residence time of section, after cooling, finishes the section solid state polycondensation.
As optimized technical scheme:
The beneficial effects of the utility model are:
