Thermal ntawv, raws li ib tug tshwj xeeb printing nruab nrab, yog dav siv nyob rau hauv lub neej txhua hnub vim nws txoj kev yooj yim luam ntawv thiab cov yam ntxwv ntawm txoj kev loj hlob ntawm lub sij hawm, tshwj xeeb tshaj yog nyob rau hauv cov teb xws li nyiaj ntsuab, daim ntawv lo luam ntawv, thiab nthuav cov ntaub ntawv. Txawm li cas los xij, qhov teeb meem ntawm seb daim ntawv thermal puas yuav ploj mus tom qab cov yas sealing muaj feem xyuam nrog cov qauv duab, cov yam ntxwv ntawm cov khoom, thiab qhov cuam tshuam ntawm cov txheej txheem yas sealing ntawm kev ruaj ntseg ntawm cov duab thermal.
Cov ntsiab cai ntawm Thermal Paper Imaging
Qhov laj thawj yog vim li cas cov ntawv thermosensitive tuaj yeem tso cov duab tom qab ua kom sov yog vim nws qhov chaw yog coated nrog cov thermosensitive txheej uas muaj cov xim tsim thiab tsim tawm (feem ntau yog acidic catalyst). Thaum lub taub hau thermosensitive heats qhov no ntawm cov txheej, cov xim tsim tawm cov tshuaj tiv thaiv nrog tus tsim tawm, tsim cov ntawv dub lossis lwm yam xim thiab cov qauv ntawm daim ntawv. Cov txheej txheem no yog irreversible, txhais tau hais tias ib zaug ib daim duab tsim, nws yuav tsis ploj mus los ntawm txias.
Fading factor tsom xam
1. Lub teeb thiab kub: Cov duab luam tawm ntawm cov ntawv thermosensitive tau yooj yim cuam tshuam los ntawm ultraviolet hluav taws xob thiab kub kub, uas ua rau kom fading. Lub sij hawm ntev raug rau lub hnub ci los yog qhov kub thiab txias ib puag ncig, txawm tias tsis muaj cov ntim yas, yuav maj mam ploj mus.
2. Humidity: Ib puag ncig cov av noo kuj tsis zoo rau kev khaws cia ntawm cov ntawv thermal. Cov dej noo tuaj yeem ua rau daim ntawv nthuav dav, cuam tshuam rau qhov pom tseeb ntawm daim duab, thiab tej zaum yuav ua rau cov duab plooj mus ntev.
3. Yas sealing cov ntaub ntawv: Lub hom phiaj ntawm yas sealing thermosensitive ntawv yog los tiv thaiv cov duab los ntawm ib puag ncig ib puag ncig cuam tshuam thiab ntev lawv lub neej cia. Cov yas yeeb yaj kiab zoo tuaj yeem cais tawm huab cua, noo noo, thiab lub teeb, uas yog qhov zoo rau kev tiv thaiv fading. Txawm li cas los xij, yog tias cov khoom ntim yas muaj qee yam tshuaj lom neeg uas cuam tshuam nrog cov txheej txheem thermosensitive, nws yuav ua rau cov duab fading lossis deformation.
4. Yas sealing txheej txheem: Yog hais tias qhov kub thiab txias heev thaum lub sij hawm cov yas sealing txheej txheem, cov xim tsim nyob rau hauv lub thermosensitive txheej tej zaum yuav reactivated, ua rau cov kev hloov nyob rau hauv cov duab. Tsis tas li ntawd, yog tias cov yas sealing tsis sib npaug thiab ua npuas lossis wrinkles, cov duab hauv cov cheeb tsam no yuav ploj mus sai dua vim yog kev sib cuag nrog huab cua.
Cov nyhuv ntawm cov yas ntim rau ntawm fading ntawm cov ntawv thermosensitive
Zuag qhia tag nrho, seb cov ntawv kub kub puas ploj tom qab tau ntim nrog cov yas loj nyob ntawm kev xaiv cov khoom sib khi thiab qhov zoo ntawm cov txheej txheem sealing. Kev ntim cov yas kom zoo tuaj yeem txhim kho qhov ua tau zoo ntawm cov ntawv thermal, tab sis yog tias ua haujlwm tsis raug lossis ua los ntawm cov khoom siv tsis zoo, nws yuav muaj kev cuam tshuam tsis zoo. Yog li ntawd, xaiv cov yas sealing zaj duab xis uas yog UV resistant, noo noo-pov thawj, thiab sib haum nrog thermosensitive txheej, thiab xyuas kom meej tias qhov kub thiab txias thaum lub sij hawm sealing txheej txheem yog nruab nrab thiab lub sealing yog zoo, yog tus yuam sij rau kev ruaj ntseg mus ntev. thermosensitive ntawv duab.
Hauv cov ntsiab lus, qhov ua tau zoo ntawm thermal ntawv yas sealing hauv kev tiv thaiv fading yog tshwm sim los ntawm ntau yam. Txoj kev sib khi thiab cov ntaub ntawv yas zoo tuaj yeem txhim kho qhov zoo ntawm cov duab khaws cia, tab sis qhov ua tau ntawm fading tsis tuaj yeem txiav tawm tag nrho, tshwj xeeb tshaj yog thaum khaws cia ntev. Txhawm rau kom ua tiav qhov khaws cia ntawm cov ntaub ntawv thermal luam ntawv, nws raug nquahu kom siv cov khoom ntim yas zoo thiab khaws cia rau hauv qhov chaw tsim nyog, zam qhov kub thiab txias, av noo, thiab teeb pom kev zoo, kom ntseeg tau lub sijhawm ntev kom pom tseeb thiab nyeem tau ntawm cov duab.
