Cov yeeb yaj kiab kho qhov muag yog txawv ntawm cov yeeb yaj kiab tiv thaiv zoo tib yam lossis daim kab xev. Nws muaj cov tuab tuab, thiab qhov saum npoo yuav tsum tsis muaj plua plav thiab ob peb cov ntsiab lus siv lead ua. Qhov no tso rau pem hauv ntej cov kev xav tau ntau dua rau cov txheej txheem txheej txheem thiab yuav tsum tau muaj ntau yam yeeb yaj kiab tuab. Yog li dab tsi yog txheej txheej tshuab ntawm optical zaj duab xis, cia cov khoom siv hluav taws xob nrog 10 xyoo kev paub hauv optical PET zaj duab xis piav qhia rau koj:
Optical zaj duab xis txheej tau ib txwm tau npaj los ntawm lub tshuab nqus tsev evaporation, chemical deposition, plasma polymerization, thiab lwm yam. Cov txheej txheem no nyuaj rau kev ua tiav loj ntawm cov yob zaj duab xis substrates; nyob rau hauv cov txheej txheem txheej niaj hnub no, cov txheej txheem txheej txheem muaj xws li dip txheej, Yob txheej, txoj kab nqes extrusion txheej, kab hlau rhuav, thiab lwm yam. Cov txheej txheem txheej no yog tsim rau cov khoom siv sib txawv thiab txheej txheej thicknesses, thiab muaj lawv tus kheej zoo thiab qhov tsis zoo. Cov txheej txheej ntawm cov txheej txheej dip tsis yooj yim los tswj thiab cuam tshuam zoo heev los ntawm cov yam ntxwv thiab kub ntawm cov khoom; Lub thickness ntawm cov txheej txheej siv los ntawm cov menyuam txheej yog yooj yim los tswj, cov txheej txheem yog yooj yim los tswj thiab cov uniformity yog zoo, tab sis nws yog heev cuam tshuam los ntawm cov yam ntxwv ntawm cov khoom Lub viscosity ntau yam ntawm cov khoom adaptable yog nqaim; Txawm hais tias cov txheej txheem ntawm txoj kab nqes extrusion txheej yog yooj yim los tswj, qhov viscosity ntau ntawm cov khoom siv tau yooj yim nqaim, cov txheej txheem me me dhau los ua ib qho yooj yim rau kev thov, thiab nws tsis tuaj yeem siv rau ntawm cov npoo, ua rau cov khoom pov tseg. substrate; Kab hlau rhuav txheej yog ib txoj kev kwv yees txheej txheem. Nws yooj yim rau kev khiav lag luam. Lub thickness ntawm txheej nyob rau hauv longitudinal thiab transverse cov lus qhia yog heev uniform. Cov txheej tsis muaj khawb, streaks, txiv kab ntxwv tev, tab sis cov ntaub thaiv tau yooj yim cuam tshuam los ntawm yam xws li tsheb ceev. Yog li ntawd, daim ntaub ruaj khov yog ib qho teeb meem loj.
