Carbonless Ntawv Dov Ntau Lawm Txheej Txheem

Daim ntawv tsis muaj ntaub ntawv tau tsim nyob rau xyoo 1945 los ntawm National Cash Register, ib lub tuam txhab hauv Teb Chaws Asmeskas Nyiaj Ntsuab. Daim ntawv no zoo li tsis txawv ntawm daim ntawv dawb, tab sis nws siv tau rau overwriting, ua cov nyhuv tib yam li daim ntawv xiav, tsis muaj cov ntiv tes thiab khaub ncaws, ua rau nws ntau dua tu cev. Vim hais tias ntawm lub chaw ua khoom ntawm daim ntawv no tsis siv daim carbon carbon, nws thiaj li hu ua carbonless daim ntawv, xa cov ntawv carbonless.

Cov ntawv tsis muaj kev pab:

Nrog rau qhov chaw ntawm cov koos pij tawj, kev tsim txoj haujlwm ntawm chaw ua haujlwm, cov ntawv carbonless yuav ua tau yooj yim luam tawm nyob rau hauv lub computer tshav dav hlau, tsim rau qhov chaw ua haujlwm automation. Cov ntawv tsis muaj cov ntawv tsis muaj sau cov ntawv tshwj xeeb, sau tag nrho cov ntawv rau daim tseem ntawv thiab ib daim luam ntau ntawm cov ntawv luam, koj tuaj yeem muab luam tawm ntau dua 6, thiab cov duab nrig xim. Daim tawv nqaij ntawm daim ntawv, qhov txheej txheem kaw, xim tshuaj, tsis muaj cwj pwm ua ntej thiab tom qab luam ntawv, tsis tau txais tes thiab hnav cov khoom nyiag, yooj yim siv, ntxuav. Vim tias kev siv cov tshuaj tsim, tshuaj tiv thaiv thiab rov sau cov teeb meem, nws daim ntawv thov tseem tuaj yeem siv ntau thiab ntau dav siv banking, kev xa ntawv, kev sib txuas lus, kev them nqi, tsheb thauj mus los, cov chaw ntiav pw, kev lis kev cai, kev tuav pov hwm thiab lwm yam.

Cov qauv tsis muaj ntaub ntawv:

Daim ntawv kuj hu ua cov ntaub ntawv tom qab (code CB), tom qab ntawm daim ntawv coated nrog ib tug quab yuam rhiab roj microcapsules, kuj paub tias daim ntawv nyob rau hauv ob npaug zoo thiab tsis zoo coated ntawv (CFB), pem hauv ntej ntawm daim ntawv coated tus tsim tawm, tom qab Coated nrog quab yuam xim xim roj microcapsules. Carbonless paper yuav muab faib ua ob hom coupling thiab nws tus kheej, cov kev siv ntau dua yog qhov sib txuas ntawm cov ntawv luam tawm cov ntawv dawb, feem ntau yog peb hom ntawv, raws li, daim ntawv, ntawv thiab ntawv. Daim ntawv ntxiv tom qab, tseem hu ua daim ntawv saum npoo (codenamed CF), daim ntawv tsuas yog muaj xim nrog tus neeg sawv cev xim. Cov ntawv pov thawj ntawm tus kheej (tseem hu ua cov ntawv sau ua tus kheej, tus qauv SC) yog coated nyob rau sab nraum qab ntawm daim ntawv uas muaj lub microencapsulated nrog cov roj ntshiab macro-rhiab, hauv ntej coated nrog ib tug coloring agent thiab micro-capsules uas muaj hwjchim-rhiab pigment. 01, lub siab hom carbonless daim ntawv thiab nws cov txheej txheem ntau lawm

02, siab tawv carbonless daim ntawv thiab nws cov txheej txheem ntau lawm

03, carbonless daim ntawv ua txoj kev

04, tseem muaj xim xim nqaij daim ntawv thiab nws cov txheej txheem ntau lawm

05, nrog nco tus password ruaj ntseg daim ntawv thiab kev ntes thiab nrhiav kev

06, cov ntawv tsis tov carbon fiber ntau carbonless thiab nws txoj kev siv ntau lawm

07, nrog bentonite Npaj cov ntawv tshwj xeeb carbonless rau cov av av nplaum tsim tshiab.
