(I) Lub hauv paus ntsiab lus ntawm kev tsim khoom
Lub hauv paus ntsiab lus ntawm cov ntawv sau nyiaj thermal yog siv cov hmoov microparticle rau ntawm daim ntawv zoo tib yam, uas yog tsim los ntawm cov xim tsis muaj xim phenol lossis lwm yam tshuaj acidic, sib cais los ntawm zaj duab xis. Nyob rau hauv cov cua kub cua sov, cov zaj duab xis melts thiab cov hmoov sib tov rau cov xim. Tshwj xeeb, daim ntawv sau npe nyiaj ntsuab feem ntau muab faib ua peb txheej. Cov txheej hauv qab yog lub hauv paus ntawv. Tom qab cov ntawv zoo tib yam raug rau kev kho saum npoo, nws yog npaj rau adhesion ntawm tshav kub-sensitive tshuaj. Qhov thib ob txheej yog thermal txheej. Cov txheej no yog kev sib xyaw ua ke ntawm ntau yam sib xyaw. Cov xim tsis muaj xim yog feem ntau yog triphenylmethanephthalide system crystal violet lactone (CVL), fluorane system, tsis muaj xim benzoyl methylene xiav (BLMB) lossis spiropyran system thiab lwm yam tshuaj lom neeg; Cov neeg tsim xim feem ntau yog para-hydroxybenzoic acid thiab nws cov esters (PHBB, PHB), salicylic acid, 2,4-dihydroxybenzoic acid los yog aromatic sulfone thiab lwm yam tshuaj lom neeg. Thaum rhuab, cov xim tsis muaj xim thiab cov xim tsim tawm cuam tshuam ib leeg los tsim cov xim xim. Cov txheej thib peb yog txheej tiv thaiv, uas yog siv los tiv thaiv cov ntawv lossis cov qauv los ntawm kev cuam tshuam los ntawm lub ntiaj teb sab nraud.
(II) Cov yam ntxwv tseem ceeb
Cov xim tsis sib xws: Cov ntawv sau nyiaj thermal tuaj yeem ua kom cov xim sib txawv thaum luam ntawv, ua rau cov ntawv luam tawm kom meej thiab nyeem tau. Cov ntawv sau nyiaj zoo thermal zoo muaj cov yam ntxwv ntawm cov xim sib xws, zoo smoothness, siab whiteness, thiab me ntsis ntsuab. Yog tias daim ntawv dawb heev, ces cov txheej tiv thaiv thiab thermal txheej ntawm daim ntawv yog tsis tsim nyog, thiab cov hmoov fluorescent ntau ntxiv.
Zoo smoothness: Lub npoo du ntawm daim ntawv tsis tsuas yog txhim kho kev luam ntawv zoo, tab sis kuj txo qhov tshwm sim ntawm lub tshuab luam ntawv jams.
Lub neej txee ntev: Raws li ib txwm muaj, cov ntawv sau rau ntawm daim ntawv sau npe nyiaj ntsuab tuaj yeem khaws cia rau ntau xyoo lossis ntev dua. Txawm li cas los xij, nws yog ib qho tsim nyog kom tsis txhob muaj hnub ci ncaj qha, qhov kub thiab txias, av noo thiab lwm qhov chaw kom tsis txhob cuam tshuam rau lub sijhawm cia. Piv txwv li, daim ntawv sau npe nyiaj ntsuab zoo tuaj yeem khaws cia rau plaub mus rau tsib xyoos.
Tsis tas yuav tsum muaj cov khoom siv luam ntawv: Cov ntawv sau nyiaj kub kub tsis siv cov pa roj carbon ribbon, ribbons lossis number case cartridges thaum siv, uas txo cov nqi siv thiab txo cov pa phem ib puag ncig.
Kev nrawm nrawm nrawm: Thermal thev naus laus zis tuaj yeem ua tiav kev luam ntawv nrawm, ncav cuag kaum rau pua pua nplooj ntawv ib feeb. Qhov no ua rau nws siv dav hauv qhov chaw xws li khw muag khoom thiab khoom noj khoom haus uas yuav tsum muaj kev sib haum xeeb sai.
Ntau yam specifications: Thermal cash register paper muaj ntau yam kev qhia tshwj xeeb thiab qhov ntau thiab tsawg los ua kom tau raws li qhov xav tau ntawm cov tshuab luam ntawv sib txawv thiab cov xwm txheej siv. Cov specifications muaj xws li 57 × 50, 57 × 60, 57 × 80, 57 × 110, 80 × 50, 80 × 60, 80 × 80, 80 × 110, thiab lwm yam. ntawm kev lag luam sib txawv.
