Carbonless carbon ntawv yog ib hom tshiab ntawm cov ntawv carbon, uas muaj peev xwm paub sau ntawv nyob rau hauv lub sab sauv txheej ntawm cov ntawv carbon, thiab kuj yuav luam tau yam tsis tas yuav tsum tau siv number case rau cov pa roj carbon txheej.
Dab tsi ntawm cov ntawv luam tawm carbonless muaj?
Raws li txoj kev sib txawv ntawm cov xim sib txawv, peb feem ntau faib cov ntawv tsis muaj carbonless rau hauv ob pawg: ib qho yog coupling hom carbonless luam ntawv, uas yog, xim tsim carbonless luam ntawv; Lwm qhov yog cov ntawv txhawb nqa tus kheej uas tsis muaj cov ntawv luam, uas yog, Cov Ntawv Xim Xim Carbonless.
Coupling type carbonless copy paper belongs rau ob-up hom, nrog rau cov nplooj ntawv sab saud (CB ntawv) thiab cov ntawv sab saud (CF ntawv). Thaum siv, daim ntawv sab saud muab tso rau ntawm txheej sab saud, thiab daim ntawv sab saud yog muab tso rau hauv qab txheej.
Yog tias koj xav tau luam ob lossis ntau nplooj ntawv, koj yuav tsum ntxiv ib lossis ntau txheej ntawm nplooj ntawv nruab nrab (CFB daim ntawv) ntawm nplooj ntawv sab sauv thiab sab qis kom paub txog ntau nplooj ntawv luam. Yog li ntawd, nyob rau hauv cov nqe lus ntawm qhov zoo sib xws thiab qhov sib txawv ntawm cov qauv, cov coupling hom carbonless daim ntawv yuav tsum tau siv nyob rau hauv ua ke nrog nrog rau sab sauv, nruab nrab thiab qis txheej.
