Ua ntej ntawm tag nrho cov, peb yuav tsum to taub dab tsi yog thermal ntawv.Thermal paper tseem hu ua thermal fax paper, thermal recording paper, thermal copy paper.Thermal ntawv raws li ib tug ua daim ntawv, nws raug cai yog nyob rau hauv qhov zoo ntawm lub hauv paus ntawv coated nrog ib tug txheej ntawm "thermal txheej" (thermal xim-hloov txheej).Txawm hais tias muaj ntau tshaj li kaum ob hom tshuaj siv nyob rau hauv cov xim-hloov txheej, muaj tsawg kawg yog cov ntsiab lus hauv qab no: cov xim tsis muaj xim, uas muaj ntau yam, feem ntau yog siv rau cov fluorescent compounds;Cov kab mob chromogenic suav txog tsawg dua 20%, feem ntau siv yog bisphenol, hydroxybenzoic acid;Sensitizers suav nrog tsawg dua 10%, uas muaj benzene sulfonamide tebchaw;Cov muab tub lim suav txog li 50% ntawm cov hauv qab no, feem ntau siv calcium carbonate (particles);Adhesives account rau tsawg dua 10%, xws li polyvinyl acetate;Stabilizers, xws li dibenzoyl phthalate;Lubricants, thiab lwm yam.
Tom qab nkag siab tias daim ntawv thermal yog dab tsi, peb mam li tham txog vim li cas cov ntawv thermal ploj.
Cov ntawv sau tsis ruaj khov uas tsim los ntawm fax lossis luam ntawv ntawm cov ntawv thermal yuav ploj mus, vim li cas cov xim ntawm cov ntawv thermal yog thim rov qab, cov khoom xim yuav decompose los ntawm nws tus kheej mus rau qhov sib txawv, thiab xim ntawm kev sau ntawv yuav maj mam ploj zuj zus ntxiv thiab. ntiav ntau dua, kom txog thaum lub ntuj ploj mus rau daim ntawv dawb kiag li ploj mus.
Yog li ntawd, lub sijhawm tso sijhawm ntev, lub teeb ci ntev, lub sijhawm cua sov ntev thiab nyob rau ntawm qhov kub thiab txias, qhov chaw ntub dej, tiv tauj daim ntawv nplaum thiab lwm yam kev mob sab nraud nyob rau hauv kev sib xyaw ua ke, yuav ua rau kom cov khoom sib xyaw xim, ua kom nws fading ceev.Ntawm chav kawm, qhov fading ceev kuj muaj feem xyuam rau lub tshav kub rhiab txheej ntawm thermal ntawv nws tus kheej.(Qhov zoo ntawm cov ntawv thermal kuj yuav txiav txim siab nws qhov nrawm nrawm).
Muaj ob peb lub ntsiab lus los txheeb xyuas qhov zoo ntawm cov ntawv thermal
1: qhov zoo tuaj yeem pom los ntawm qhov tsos.Yog tias daim ntawv dawb heev, daim ntawv tiv thaiv txheej thiab thermal txheej tsis tsim nyog, ntxiv phosphor ntau dhau, zoo dua yuav tsum ntsuab me ntsis.Cov ntawv tsis sib xws, qhia tias cov ntawv txheej tsis sib xws, yog tias daim ntawv pom lub teeb muaj zog heev, nws yog phosphor ntau dhau, tsis zoo heev.
2: hluav taws ci: txoj kev no yooj yim heev, yog siv lub teeb kom sov rau sab nraum qab ntawm cov ntawv thermal, tom qab cua sov, xim yog xim av, qhia tias cov mis thermal tsis tsim nyog, lub sij hawm khaws cia yog luv.Yog tias muaj cov streaks me me los yog qhov tsis sib xws hauv cov xim dub tom qab cua sov, cov txheej tsis zoo faib.Tom qab cua sov, cov xim yog xim dub thiab ntsuab, thiab kev faib tawm ntawm cov xim blocks yog qhov sib xws, thiab xim dhau los ua lub teeb ntawm qhov chaw mus rau ib puag ncig.
3: tshav ntuj raug tshav kub: cov ntawv luam tawm yog smeated nrog ib tug highlighter thiab raug rau lub hnub (nyob rau hauv thiaj li yuav ua kom lub sij hawm ntawm cov tshuaj tiv thaiv ntawm tshav kub-sensitive txheej), uas yuav tig dub ceev tshaj, qhia lub sij hawm luv tshaj.Qhov zoo yog qhov phem tshaj.
Tam sim no, cov tshuab luam ntawv bar code feem ntau luam tawm ob txoj hauv kev.Ib qho yog peb cov thermal luam ntawv, cov ntawv luam tawm bar code, feem ntau, lub sij hawm khaws cia yog luv luv, yooj yim rau ploj hauv qhov kub thiab txias.Tab sis qhov txiaj ntsig ntawm thermal luam ntawv yog tias nws tsis xav tau cov kab xev carbon, yooj yim rau nruab, yooj yim luam tawm, tsis muaj wrinkles, thiab lwm yam.
Kuj tseem muaj txoj hauv kev hloov pauv cua sov, tseem hu ua carbon tape printing.Nws qhov zoo dua yog tias cov ntawv luam tawm tuaj yeem khaws cia rau lub sijhawm ntev, thiab nws kuj tuaj yeem tiv taus qhov kub thiab txias ib puag ncig.
