Cov ntawv luam tawm tsis muaj cov pa roj carbon monoxide, tseem hu ua cov ntawv siab-rhiab heev lossis NCR daim ntawv (Tsis Xav Tau Carbon), yog ib hom ntawv tshwj xeeb uas tuaj yeem tso cov ntawv sau meej meej ntawm ntau cov ntaub ntawv yam tsis tas yuav tsum muaj cov ntawv luam tawm ib txwm muaj. Nws yog dav siv nyob rau hauv kev lag luam, chaw ua haujlwm, tuam txhab nyiaj, se thiab lwm yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum muaj ntau daim ntawv theej, daim ntawv txais nyiaj, xaj, thiab lwm yam, cov ntawv luam ntawv tsis muaj cov pa roj carbon monoxide muab kev yooj yim thiab ua haujlwm zoo. Yog li, muaj pes tsawg txheej ntawm cov ntawv luam tawm carbon dawb muaj?
Cov ntawv luam tawm carbon dawb feem ntau yog tsim los ntawm peb txheej ntawm daim ntawv, txhua tus nrog nws cov haujlwm tshwj xeeb:
1. Sab saum toj txheej ntawv (CB daim ntawv): Qhov no yog txheej ntawm daim ntawv ncaj qha los ntawm tus kws sau ntawv, nrog ib txheej ntawm microcapsules coated rau sab nraub qaum, uas muaj cov xim tsis muaj xim nyob hauv. Thaum sau ntawv lossis luam ntawv siab yog siv rau txheej ntawm daim ntawv no, lub microcapsules tawg, tso cov xim thiab tsim cov ntawv lossis cov qauv ntawm daim ntawv hauv qab.
2. Intermediate layer paper (CFB paper): Lub pem hauv ntej ntawm cov ntawv txheej no tau txais cov dye los ntawm cov ntaub ntawv saum toj kawg nkaus, thiab sab nraub qaum muaj microcapsules txuas ntxiv xa cov ntaub ntawv thaum muaj lwm cov txheej txheem hauv qab no. Kev ua haujlwm ntawm CFB daim ntawv yog zoo li tus choj, kom ntseeg tau tias cov ntaub ntawv kis tau los ntawm cov txheej txheem sab saum toj mus rau cov txheej txheem tob.
3. Cov ntawv hauv qab (CF daim ntawv): Qhov no yog txheej hauv qab ntawm daim ntawv, uas tsuas yog coated nrog cov xim tsim tus neeg sawv cev ntawm nws sab xub ntiag. Thaum cov dye tuaj rau hauv kev sib cuag nrog cov xim tsim tus neeg sawv cev, xim dub lossis lwm cov ntawv xim lossis cov qauv yuav tshwm sim. Yog tias tsuas yog xav tau ob daim ntawv luam, daim ntawv hauv qab yuav tau txais cov ntaub ntawv ncaj qha los ntawm txheej saum toj kawg nkaus; Yog tias muaj ntau cov khaubncaws sab nraud povtseg, nws yog qhov kawg rau cov ntaub ntawv xa mus.
Nws yog ib qho tsim nyog sau cia tias txawm hais tias tus qauv carbon dawb luam ntawv feem ntau muaj peb txheej, hauv kev siv tswv yim, tuaj yeem ua ke ntawm ob, peb, lossis ntau txheej nyob ntawm qhov yuav tsum tau ua. Piv txwv li, hauv qee cov ntaub ntawv yooj yim ob npaug, tsuas yog daim ntawv CB thiab CF daim ntawv yuav xav tau, tsis tas yuav tsum muaj daim ntawv CFB nruab nrab. Hauv ntau cov ntaub ntawv nyuaj, ntau txheej ntawm CFB daim ntawv yuav tsum tau ua kom paub meej cov ntaub ntawv raug.
Lub invention ntawm carbon dawb daim ntawv zoo heev simplifies lub chaw ua hauj lwm txheej txheem, txhim kho kev ua hauj lwm efficiency, thiab txo ib puag ncig cuam tshuam ntawm ib txwm luam ntawv. Nws yog ib qho tseem ceeb technology innovation. Nrog rau kev txhim kho thev naus laus zis, txawm hais tias cov ntaub ntawv hluav taws xob thiab cov ntawv kos npe digital tau maj mam hloov cov ntaub ntawv, carbon dawb daim ntawv tseem tsis tau hloov pauv hauv qee qhov xwm txheej. Nws txuas ntxiv ua haujlwm rau ntau yam ntawm cov neeg niaj hnub no nrog nws qhov tshwj xeeb zoo.
