Thermal paper yog ib daim ntawv siv dav siv nrog cov tshuaj uas hloov xim thaum rhuab.Cov cuab yeej tshwj xeeb no ua rau nws zoo tagnrho rau siv ntau yam kev siv nrog rau daim ntawv txais nyiaj, daim ntawv lo thiab daim pib.Yuav kom nkag siab txog cov tshuaj muaj pes tsawg leeg ntawm cov ntawv thermal, nws yog ib qho tseem ceeb kom nkag siab txog cov khoom xyaw tseem ceeb uas tso cai rau nws ua nws txoj haujlwm.
Cov tshuaj lom neeg tseem ceeb ntawm cov ntawv thermal yog cov xim kub-sensitive dyes.Cov xim no feem ntau yog cov xim tsis muaj xim uas dhau los ua cov tshuaj tiv thaiv thaum rhuab, ua rau pom xim hloov.Cov dyes feem ntau siv hauv cov ntawv thermal yog leuco dyes, uas paub txog lawv cov xim hloov pauv tau.Thaum cov ntawv thermal yog rhuab, cov xim tsis muaj xim tau dhau los ua cov txheej txheem hu ua thermochromism, ua rau nws hloov ntawm lub xeev tsis muaj xim mus rau lub xeev xim.Qhov kev hloov xim no yog qhov tsim cov duab pom thiab cov ntawv ntawm cov ntawv thermal.
Ntxiv nrog rau cov xim, cov ntawv thermal kuj muaj cov tshuaj tsim tawm.Tus tsim tawm feem ntau yog cov xim tsis muaj kua qaub uas ua rau cov xim pleev xim thaum sov, ua rau cov xim hloov xim.Tus tsim tawm ua lub luag haujlwm tseem ceeb hauv cov txheej txheem luam ntawv thermal, txhawb kev hloov xim ntawm cov dye thiab xyuas kom meej tias cov duab luam tawm thiab cov ntawv luam tawm meej thiab pom tseeb.
Tsis tas li ntawd, cov ntawv thermal muaj cov txheej txheem tiv thaiv uas pab tiv thaiv cov duab luam tawm thiab cov ntawv.Cov txheej no feem ntau yog tsim los ntawm kev sib xyaw ntawm cov tshuaj xws li cov quav ciab thiab cov resins los muab cov txheej txheem tiv thaiv ntawm cov ntawv luam tawm.Cov txheej tiv thaiv tsis tsuas yog pab tiv thaiv cov ntawv luam tawm los ntawm smudging thiab fading, tab sis kuj txhim kho tag nrho cov durability ntawm thermal ntawv.
Nws yog ib qho tsim nyog sau cia tias cov tshuaj muaj pes tsawg leeg ntawm cov ntawv thermal tuaj yeem sib txawv nyob ntawm seb nws xav siv.Piv txwv li, cov ntawv thermal siv rau cov ntawv txais nyiaj yuav muaj cov tshuaj sib txawv dua li cov ntawv thermal siv rau cov ntawv lossis daim pib.Cov neeg tsim khoom tuaj yeem kho cov tshuaj muaj pes tsawg leeg ntawm cov ntawv thermal kom tau raws li cov kev xav tau tshwj xeeb, xws li ploj tsis kam, dej tsis kam, lossis kev sib raug zoo nrog cov tshuab luam ntawv sib txawv.
Thaum cov ntawv thermal muaj ntau yam zoo, nrog rau kev luam ntawv ceev thiab tus nqi qis, nws yuav tsum tau ua tib zoo saib xyuas vim nws cov tshuaj muaj pes tsawg leeg.Kev cuam tshuam rau qee yam tshuaj los yog qhov kub thiab txias tuaj yeem cuam tshuam rau kev ua haujlwm thiab lub neej ntawm cov ntawv thermal.Txoj kev khaws cia thiab tuav kom zoo yog qhov tseem ceeb kom ntseeg tau tias cov ntawv thermal tseem nyob hauv qhov zoo rau kev siv.
Hauv cov ntsiab lus, kev nkag siab txog cov tshuaj muaj pes tsawg leeg ntawm cov ntawv thermal yog qhov tseem ceeb rau kev nkag siab nws cov khoom tshwj xeeb thiab kev siv.Kev sib xyaw ua ke ntawm thermal dyes, cov tshuaj tsim tawm, thiab cov txheej txheem tiv thaiv ua kom cov ntawv thermal xa cov txiaj ntsig zoo, sai sai.Nrog rau kev nkag siab tob txog cov tshuaj muaj pes tsawg leeg ntawm cov ntawv thermal, cov neeg siv tuaj yeem txiav txim siab txog nws txoj kev siv thiab kev khaws cia, thaum kawg ua kom nws cov txiaj ntsig tau zoo hauv ntau yam kev siv luam ntawv.
