Carbonless Paper Dov Hnub Tuaj Qhov Teeb Tseem Ceeb
Aug 22, 2017

Carbonless Paper Roll Teeb meem tam sim no

Keeb kwm ntawm carbonless daim ntawv

Cov ntawv tsis muaj ntawv nyeem uas tsis hu ua Carbonless copy, xa mus rau CCP. Daim ntawv tsis muaj ntawv npaj tau npaj tau los ntawm US Congress Cash Cashier (NCR) hauv xyoo 1953, cov ntawv carbonless, kuj hu ua NCR daim ntawv. Lub ntiaj teb no cov ntawv carbonless hauv 70-80 xyoo ntawm kev loj hlob sai, lub caij nyoog 90s hlob qeeb, hauv 2001 lub ntiaj teb tawm ntawm 300 lab tons. Tuam Tshoj cov ntawv dawb-dawb cov ntawv nyob rau xyoo 1970s, 90 xyoo ntawm kev loj hlob sai.

Non-carbon daim ntawv xim

Nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, zuaj cov microcapsules, uas cov leuco dye txeej reacts nrog cov xim reagent rau sab nraud, thiab cov duab dub los yog xiav lossis cov ntawv sau qhia rau ntawm daim ntawv coated nrog tus tsim tawm, Qhov teeb meem tau muab faib rau ntau daim ntawv luam thiab cov ntawv luam. Kev luam ntau daim ntawv los ntawm daim ntawv (CB), daim ntawv xov xwm (CFB), daim ntawv ntxiv (CF), daim duab qauv yog raws li nram no:

Daim ntawv CFB yog coated nrog ib txheej ntawm tus tsim tawm ntawm sab saud (sab pem hauv ntej), thiab ib txheej ntawm microcapsules nyob tom qab (rov qab) coated nrog ib txheej ntawm microcapsules; CFB daim ntawv yog coated nrog ib txheej ntawm microcapsules nyob tom qab (sab nraum qab) Daim ntawv yog coated nrog ib txheej ntawm tus tsim ntawm sab saum toj (sab pem hauv ntej), yog li cov pa carbonless ntawm daim ntawv carbonless tsis yog rov qab rau qhov ntawm CF qhov chaw (xws li, cov microcapsules thiab tus tsim tawm).

Cov yam ntxwv ntawm carbonless daim ntawv

Qhov zoo: 1, ib qho yooj yim siv, ntxuav tsis ua rau tes 2, luam cov xov tooj, sau ntawv 3, yooj yim ua, overprinting tidy 4, siv cov tshuaj xim, yooj yim dua sau dua tshiab thiab ntaus 5, tshwj xeeb tshaj yog rau computer luam ntawv

Disadvantages: ntau dua cov nqi

Daim ntawv thov ntawm carbonless daim ntawv

4, computer luam ntawv 5, nyeem ntawv nyeem ntawv 6, ntawv cim 7, tsheb, ntawv nyeem, ntawv kho mob,

Lub ntsiab raw ntawm carbonless daim ntawv

Cov ntawv tsis muaj phom xyaw Cov khoom xyaw: 1, lub hauv paus ntawv

2, CB a, microcapsules (leuco dye) b, spacer c, binder

3, CF a, xim tawv reagent b, xim c, ntawv tuav
