Cov ntawv tsis muaj cov pa roj carbon monoxide, ua ib hom ntawv tshwj xeeb uas tau siv dav hauv cov chaw ua haujlwm niaj hnub thiab cov ntaub ntawv sau tseg, yog qhov muaj peev xwm ua tiav ntau daim ntawv luam yam tsis tas yuav tsum muaj cov pa roj carbon monoxide lossis cov ntawv luam tawm, txhim kho kev ua haujlwm zoo thiab txo cov pa phem ib puag ncig. Nov yog qee cov yam ntxwv tseem ceeb ntawm carbonless ntawv:
1. Self loading xim tshuab
Cov thev naus laus zis tseem ceeb ntawm cov ntawv tsis muaj carbonless nyob hauv nws tus kheej thauj khoom xim txheej qauv. Hom ntawv no feem ntau yog tsim los ntawm ntau txheej, nrog rau cov xim tshwj xeeb microcapsule thiab xim coated ntawm txhua txheej. Thaum sau ntawv siab yog siv rau txheej saum toj kawg nkaus, microcapsules rupture, tso cov pigments uas hnov mob nrog cov txheej txheem tom ntej ntawm cov xim tsim, yog li nthuav tawm cov ntawv lossis cov qauv ntawm daim ntawv, ua tiav cov txiaj ntsig luam tawm yam tsis xav tau cov ntawv carbon ntxiv. Cov txheej txheem no ua kom ntseeg tau tias txawm tias nyob hauv ntau cov ntaub ntawv, kev sau ntawv ntawm txhua daim ntawv yog qhov tseeb thiab paub qhov txawv.
2. Kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob
Vim tias cov ntawv carbonless tsis xav tau cov ntawv carbon ntxiv los pab rau kev luam, nws txo cov ntawv siv thiab pov tseg, uas yog nyob rau hauv txoj kab nrog lub tswv yim ntsuab chaw ua haujlwm raws li niaj hnub kev lag luam. Nws tsis tsuas yog txo cov peev txheej pov tseg, tab sis kuj zam kev ua qias tuaj ib puag ncig uas cov ntawv carbon ib txwm tuaj yeem nqa, uas yog qhov tsim nyog rau kev txhim kho kom ruaj khov.
3. Yooj yim rau siv
Carbonless ntawv ua kom yooj yim rau cov txheej txheem theej, tso cai rau cov neeg siv tsuas yog sau ib daim ntawv lossis daim ntawv cog lus thiab cia li luam cov ntawv luam hauv qab no, txuag lub sijhawm thiab nqi zog. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam ceev ceev, qhov ua tau zoo ntawm cov ntawv tsis muaj cov ntawv carbonless yog qhov tseem ceeb, tsim nyog rau kev tsim cov ntaub ntawv ntau yam xws li cov ntawv xa nyiaj, cov ntawv txais nyiaj, cov ntawv cog lus, cov ntawv ceeb toom, thiab lwm yam.
4. Kev sau ntawv ntev ntev thiab meej
Piv nrog rau cov ntawv tsis tu ncua, cov ntawv sau rau ntawm cov ntawv tsis muaj cov pa roj carbon monoxide yog qhov ruaj khov thiab tsis tshua muaj fading. Qhov no yog vim qhov ruaj khov ntawm cov ntawv sau los ntawm nws cov tshuaj tiv thaiv xim zoo. Txawm tias tom qab lub sij hawm ntev cia los yog nquag flipping, cov ntawv sau ntawv tseem pom tseeb thiab pom, kom ntseeg tau cov nqi khaws cia ntev thiab kev raug cai ntawm cov ntaub ntawv.
5. Diversified daim ntawv thov
Carbonless ntawv tuaj yeem tsim los ntawm cov xim sib txawv thiab cov lus qhia tshwj xeeb raws li cov kev xav tau sib txawv, xws li cov xim sib xws xws li xiav, liab, ntsuab, thiab lwm yam, kom paub qhov txawv ntawm qhov sib txuas lossis cov ntaub ntawv tseem ceeb. Tsis tas li ntawd, nws tseem tuaj yeem hloov kho rau ntau hom ntawv xws li kab rov tav, ntsug, thiab qhov khoob kom tau raws li cov kev xav tau ntawm cov kev lag luam sib txawv thiab cov xwm txheej, xws li nyiaj txiag, kev tuav pov hwm, kev thauj mus los, kev kho mob, thiab lwm yam.
6. Kev ruaj ntseg siab
Kev siv cov ntawv tsis muaj cov ntawv carbonless kuj ua rau muaj kev ruaj ntseg ntawm cov ntaub ntawv. Vim nws qhov tshwj xeeb kev tsim kho, nws yog ib qho nyuaj rau tamper nrog, ua rau nws tseem ceeb heev rau cov ntaub ntawv uas yuav tsum tau tswj xyuas qhov tseeb ntawm lawv cov ntaub ntawv qub. Lub caij no, nws tseem tuaj yeem txo qhov kev pheej hmoo ntawm cov ntaub ntawv tawm thaum lub sijhawm luam lossis luam theej duab, vim tias tsis muaj cov kauj ruam luam ntxiv ntxiv.
Hauv cov ntsiab lus, cov ntawv tsis muaj cov pa roj carbon monoxide ua lub luag haujlwm tseem ceeb hauv lub neej niaj hnub no vim nws muaj ntau yam zoo xws li kev tiv thaiv ib puag ncig, kev ua haujlwm zoo, yooj yim, durability, ntau haiv neeg, thiab kev nyab xeeb. Nrog rau kev nce qib ntawm thev naus laus zis tsis tu ncua thiab txhim kho kev paub txog ib puag ncig, daim ntawv thov ntawm cov ntawv tsis muaj carbon yuav txuas ntxiv mus ntxiv, dhau los ua lub zog tseem ceeb hauv kev txhawb nqa chaw ua haujlwm automation thiab chaw ua haujlwm ntsuab. Thaum xaiv cov ntaub ntawv hauv chaw ua haujlwm, cov lag luam thiab cov tib neeg xav txog kev siv cov ntawv tsis muaj cov pa roj carbon monoxide tsis yog los txhim kho kev ua haujlwm zoo, tab sis kuj yog lub luag haujlwm rau kev tiv thaiv ib puag ncig.
