Kev hloov thermal thiab cov pa ncaj qha yog ob txoj kev xaiv rau luam tawm cov ntaub ntawv sib txawv ntawm cov cim npe thiab daim ntawv lo. IIMAK piav qhia qhov sib txawv ntawm cov thev naus laus zis thiab yuav ua li cas xaiv cov txheej txheem kho rau koj daim ntawv thov.
Dab tsi yog ncaj qha thermal?
Cov cua kub ncaj qhaluam ntawv siv cov tshuaj kho, tshav kub daim ntawv lo cim cov khoom uas tsaus ntuj nti thaum raug kub los ntawm lub thermal printhead. Leuco zas xim yog qhov tseem ceeb muaj nyob rau hauv cov Science News for KIDS uas tso cai rau cov tshuaj tiv thaiv tshav kub no qhov chaw. Cov tshuab luam ntawv ncaj qha tsis muaj number case, toner, lossis ribbon. Qhov kev tsim qauv no ua rau ncaj qha mus rau kev siv tau yooj yim. Txawm li cas los xij, vim hais tias cov ntawv luam tawm ncaj qha rau cov khoom siv hluav taws xob muaj cov kws kho mob kom tsaus ntuj thoob plaws hauv nws lub neej, qhov kev tawm tsam tsaus nti no tuaj yeem tshwm sim yam tsis xav txog thaum twg cov khoom kis tau kub. Cov fading zoo sib xws tuaj yeem tshwm sim nrog UV raug. Cov khoom siv ncaj qha rau cov thermal tau xaiv ntau hom ntawv thiab zaj duab xis nrog ntau qib tsis zoo, nyob ntawm saum toj kawg nkaus.

Thermal Hloov Yog Dab Tsi?
Hauvcua sov hloovluam ntawv, ib lub thermal hloov xev thawm xaj yog tsim cov duab ntawm thermal hloov chaw txais yuav cov cim npe thiab cov ntawv lo. Cov xov xwm tshaj tawm thiab xov xov ncig ua ke nyob rau hauv lub tshav kub taub hau. Raws li cov ncauj lus luam tawm raug rhaub, tus number case tau hloov los ntawm kab xov mus rau cov xov xwm txais tos los tsim cov ntawv luam tawm. Cov xov xaum xim muaj lub nraub qaum uas txuas nrog qhov luam tawm thiab tiv thaiv nws los ntawm kev sib cuag nrog daim ntawv lo nto txuas ntxiv lub neej printhead. Muaj ntau ntawm cov xov xwm thiab hom number case uas tuaj yeem siv los hloov rau txhua qhov kev thov thiab kev ua kom ntev.

Yuav ua li cas xaiv cov tshuab thev naus laus zis?
Cov cua kub ncaj qha yog qhov tsim nyog rau cov kev siv yooj yim uas muaj lub neej luv-nyob rau hauv ib puag ncig nrog kev tiv thaiv UV tsawg. Thaum tshav kub ncaj qha xav tau tsuas yog ib hom xov xwm, cov khoom siv daim ntawv lo yog nyob rau hauv kev sib txuas lus thiab tsis tu ncua nrog lub taub hau luam ntawv, uas tuaj yeem nce hnav thiab kom luv luv printhead lifespan. Los ntawm kev siv cov ntawv sau sib txawv thiab daim kab xev tsim, thermal hloov luam ntawv tuaj yeem siv rau ntau yam kev siv, los ntawm kev luam tawm niaj hnub yooj yim mus rau qhov chaw ib puag ncig hnyav. Cov hloov pob hluav taws xob hloov tau yooj yim tuaj yeem tiv taus cua sov, hnub ci, puas thiab tshuaj lom neeg ntau dua li cov cua kub ncaj qha thiab vim li ntawd tuaj yeem tsim cov luam ntawv siab dua, ua kom ntev dua thiab daim ntawv lo ntev dua.
Ntsiab Lus Sib Piv
| Cov Ncauj Ntshav ncaj | Thermal Hloov | |
| Luam Ntawv Zoo | (+)Cov ntawv luam tawm zoo tuaj yeem sib txawv raws qib kawm. Cov ntawv cim tsis yog kev lag luam saum toj kawg nkaus (kev lag luam) tuaj yeem yog lub teeb xim dub nrog hazy luam tawm zoo uas yuav cuam tshuam rau barcode scanability. | (+)Ntse, ntab, tsaus dub luam tawm zoo thiab muaj peev xwm luam tawm tau zoo heev nrog txhua tus nplua nuj. (+)Daj cua sov hloov lwm yam khoom siv ua kom pom cov kev cim rau kev cim. |
| Lub sijhawm ruaj | (-)Cov kab hluav taws xob ncaj qha yuav tsaus thaum lub ntuj kub thiab yuav ploj nrog kev raug UV. (-)Raug tau yooj yim rau scuffing thiab marring nrog abrasion thiab hnav thiab rhuav. | (+)Daim ntawv lo kom zoo thiab daim npoo txuas yuav tuaj yeem tiv taus tshav kub, tshav ntuj, ua puas thiab tshuaj lom. |
| Sau Ceev | (-)Qeeb qeeb pom zoo kom pom zoo. | (+)Cov ntawv nrawm dua tau. |
| Yooj Yim Siv | (+)Ib tus siv tau yooj yim dua rau kev txhim kho thiab tswj cov khoom tuav. | (-)Txawm hais tias ob lub koomhaum xav tau, cov ntaub ntawv yooj yim los ntawm ib qho kev sib xyaw. |
| Thov | (-)Lub neej luv. | (+)Archival zoo ntawm uas yuav kav zoo dua 1 xyoo. |
| Media / Tshuag xaiv | (-)Cov khoom lag luam tsawg tsawg ntawm cov ntawv thiab cov yeeb yaj kiab tso tawm muaj nrog cov khoom siv thermal kom ncaj. | (+)Cov khoom lag luam ntau ntawm cov substrates thiab number case kom tau raws li qhov xav tau thov. |
| Txij Nkawm Cov Nqi | (-)Printhead lub neej yog qis dua. Raws li lub tshuab luam ntawv OEM, cov taub hau yuav tsum ntev 25-50% ntawm lub neej ntawm thermal hloov printhead. | (+)Lub nraub qaum ntawm txoj hlua khi tiv thaiv printhead los ntawm xeb xaim ua los ntawm cov Tshuag. Qhov no tso cai rau lub thermal hloov printhead kom outlast ncaj qha thermal printhead los ntawm 2-4x. |
