Ua ntej tshaj plaws, peb yuav tsum nkag siab qhov yog thermal ntawv. Thermal ntawv yog tseem hu ua thermal fax ntawv, thermal cov ntaub ntawv sau cia, thermal daim ntawv ntawv. Thermal ntawv ua daim ntawv ua haujlwm, nws cov qauv tsim qauv yog qhov zoo ntawm lub hauv paus ntawv coated nrog ib txheej ntawm "Thermal txheej" (thermal xim-hloov cov txheej). Txawm hais tias muaj ntau dua li ib qho tshuaj lom neeg siv hauv cov txheej txheem xim-hloov, muaj ntau yam nyob hauv qab no: tsis muaj ntau yam, feem ntau siv rau fluorescent sib txuas; Cov neeg sawv cev chromogenic cov nyiaj rau tsawg dua 20%, feem ntau siv yog bisphenol, hydroxybenzoic acid; Cov ntsiab lus tseem ceeb rau tsawg dua 10%, uas muaj benzene sulfonamide compounds; Tus muab tub lim rau cov tub lim rau kwv yees li 50% ntawm cov hauv qab no, siv cov calcium carbonate (cov lus); Adhesives account rau tsawg dua 10%, xws li polyvinyl acetate; Stabilizers, xws li Dibenzoyl phthalate; Rojricants, thiab lwm yam.
Tom qab nkag siab txog dab tsi thermal ntawv yog, tom qab ntawd peb mam li tham txog vim li cas cov ntawv thermal fades.
Cov ntawv sau tsis ruaj khov tsim los ntawm fev lossis luam tawm ntawm cov ntawv sau ua ke yuav ploj mus, cov xim ntawm cov khoom siv sib txawv, kom txog thaum lub ntsej muag ploj mus.
Yog li no, lub sijhawm ntev kev kawm lub sijhawm, lub sijhawm ntev ntev, yuav ua kom muaj qhov chaw nyob hauv tsev, sib tiv tauj cov kab ke Ntawm chav kawm, kev fading ceev kuj muaj feem xyuam rau cov cua sov rhiab txheej ntawm cov ntawv thermal nws tus kheej. (Qhov zoo ntawm cov ntawv ua tau zoo kuj tseem yuav txiav txim siab nws fading ceev).
Muaj ob peb lub ntsiab lus los txheeb xyuas qhov zoo ntawm cov ntawv thermal
1: Qhov zoo tuaj yeem pom los ntawm cov tsos. Yog tias daim ntawv yog dawb heev, daim ntawv tiv thaiv txheej thiab thermal txheej thiab thermal txheej yog tsis tsim nyog, ntxiv ntau heev phosphor, zoo dua yuav tsum tau ntsuab me ntsis. Daim ntawv tsis ncaj, qhia tias cov ntawv txheej tsis zoo, yog tias cov ntawv cuam tshuam tau muaj zog dhau lawm, nws yog qhov zoo heev phosphor, tsis zoo heev.
2: Hluav Taws Kub: Cov qauv no yooj yim heev, yog kom siv lub ntais ntawv kom sov sab nraub qaum, tom qab cov xim cua sov, yog tias lub sijhawm cua sov tsis tsim nyog, lub sijhawm khaws cia yog luv. Yog tias muaj cov nqaij tawv me me los yog thaj ua rau thaj hauv cov xim dub tom qab cua sov, txheej tsis tau faib kom zoo. Tom qab cua sov, cov xim yog xim dub thiab ntsuab, thiab kev faib tawm cov xim xim yog cov khoom sib xyaw ua ke, thiab cov xim ua lub teeb los ntawm qhov chaw mus rau ib puag ncig.
3: Tshav ntuj raug: Cov ntawv luam tawm tau ua rau muaj lub hnub siab thiab raug tshem tawm cov tshuaj tiv thaiv tshav ntuj), uas yuav tig los ntawm cov tshuaj tiv thaiv cua sov, qhia txog lub sijhawm luv tshaj plaws. Qhov zoo yog qhov phem tshaj.
Tam sim no, bar code luam tawm feem ntau luam tawm hauv ob txoj kev. Ib qho yog peb lub thermal luam ntawv, luam tawm bar code daim ntawv lo, feem ntau, lub sijhawm khaws cia yog qhov luv luv, yooj yim rau kev ploj mus rau hauv ib puag ncig kub siab. Tab sis cov txiaj ntsig ntawm lub tshuab luam ntawv thermal yog tias nws tsis xav tau cov kab xev ntawm cov kab xev carbon, yooj yim rau nruab, yooj yim luam tawm, tsis muaj wrinkles, thiab lwm yam.
Kuj tseem muaj cov txheej txheem cua sov hloov chaw, tseem hu ua cov kab xev cov ntaub luam tawm. Nws qhov zoo dua yog tias cov ntawv luam tawm tuaj yeem khaws cia tau ntev, thiab nws tseem tuaj yeem tiv taus qhov siab thiab kub thiab txias.
