Raws li cov khoom siv zaj duab xis nyias ua ke nrog cov pob tshab siab thiab kev tiv thaiv zoo heev, molding zoo ntawm glossy laminate ncaj qha cuam tshuam rau qhov kawg kho qhov muag kev ua tau zoo thiab kav ntev. Cov txheej txheem molding yog ib kauj ruam tseem ceeb hauv kev hloov ua ntej -formulated multilayer functional cov ntaub ntawv rau hauv ib tug integrated zaj duab xis qauv. Nws suav nrog ntau yam txheej txheem, suav nrog kev npaj substrate, txheej thiab lamination, kho saum npoo, thiab winding thiab shaping. Kev sib koom ua ke ntawm qhov tsis xws li qhov kub thiab txias, siab, thiab ceev yuav tsum tau ua kom lub ntsej muag du, muaj zog interlayer kev sib raug zoo, thiab zoo li gloss.
Ua ntej, txheej txheej substrate feem ntau yog tsim los ntawm extrusion lossis biaxial stretching txheej txheem. Siv polyester los yog polypropylene thermoplastic resin ua raw khoom, nws yog yaj-extruded rau hauv ib daim ntawv tuab, thiab ces ib txhij stretched longitudinally thiab transversely los txhim kho molecular orientation, yog li ua tau zoo txhua yam muaj zog thiab seem stability. Qhov ntsuas kub thiab ncab tus nqi yuav tsum nruj me ntsis tswj nyob rau theem no los tiv thaiv thickness deviations los yog molecular saw breakage, uas yuav cuam tshuam rau cov uniformity ntawm tom ntej lamination.
Tom qab ntawd los ntawm txheej txheej thiab lamination. Cov nplaum nplaum thiab txheej tiv thaiv feem ntau yog siv rau qhov chaw ntawm lub substrate siv microgravure, comma rollers, lossis slit tuag. Cov tshuaj txheej yuav tsum muaj cov viscosity tsim nyog thiab cov khoom khib nyiab thiab kis tau tusyees nyob rau hauv ib puag ncig qhov kub thiab txias kom tsis txhob muaj txheej txheej thickness fluctuations vim qhov sib txawv ntawm cov kuab tshuaj evaporation. Thaum lub sij hawm lamination, coated substrate thiab tso tawm txheej yog stacked ntawm rhuab nias rollers. Kub nias melts cov nplaum txheej thiab tsim interfacial diffusion, tsim ib tug nruam thiab ruaj khov interlayer daim ntawv cog lus. Lub siab tsis txaus tuaj yeem ua rau cov npuas seem, thaum lub siab ntau dhau tuaj yeem ua rau lub ntsej muag microtexture puas tsuaj thiab ua rau cov nyhuv gloss tsis muaj zog.
Yuav kom tau txais qhov zoo tshaj plaws glossy tsos, cov txheej txheem molding kuj suav nrog cov kauj ruam kho saum npoo. Cov txheej txheem muaj xws li online micro-embossing thiab ntshav lossis UV curing polishing. Cov qub siv lub siab chais los tsim microstructures tsis tu ncua los coj kev taw qhia lub teeb pom kev, thaum lub tom kawg txhim kho lub zog saum npoo ntawm txheej thiab tshem tawm me me imperfections, txhim kho specular reflectivity. Cov kauj ruam no yuav tsum muaj cov cuab yeej siab precision thiab kev ua haujlwm ruaj khov thiab yuav tsum tau ua nyob rau hauv qhov chaw huv si kom tsis txhob muaj qhov adhesion los ntawm kev puas tsuaj rau qhov muag pom.
Thaum kawg, qhov txias txias, traction, thiab nro- tswj cov txheej txheem winding thiab shaping kom ntseeg tau tias cov yeeb yaj kiab yob muaj qhov tsim nyog nruj thiab lub ntsej muag zoo huv si, tiv thaiv kev ntxhov siab los yog zaj duab xis nto undulations thaum lub sij hawm cia thiab siv tom ntej. Tag nrho cov txheej txheem molding qhia txog kev sib koom ua ke ntawm ntau yam txheej txheem; deviations nyob rau hauv txhua kauj ruam tuaj yeem ua rau qhov tsis sib xws, adhesion tsis ua haujlwm, lossis txo cov khoom siv tshuab.
Hauv cov ntsiab lus, cov txheej txheem molding ntawm glossy laminated films integrates polymer khoom ua thiab precision txheej tshuab. Los ntawm kev tswj xyuas qhov kub, siab, ceev, thiab qhov chaw morphology, nws ua tiav qhov kev sib koom ua ke ntawm cov txheej txheem ua haujlwm thiab kev nthuav qhia kho qhov muag zoo heev, tso lub hauv paus ruaj khov rau nws txoj kev ntseeg siab thiab kev zoo nkauj hauv kev siv tswv yim.
