Muaj qhov sib txawv ntawm cov ntawv tsis muaj cov ntawv luam tawm thiab cov ntawv luam cov pa roj carbon, tab sis tom qab kev tsim khoom thiab ua tiav rau hauv cov ntawv luam carbon, qhov sib txawv thiab qhov txawv ntawm lawv li cas?
Carbonless daim ntawv yuav muab faib ua ob hom: xim thiab nws tus kheej-xim. Cov ntawv luam tawm xim tsis muaj xim yog siv ntau dua. Feem ntau hais lus, nws yog tsim los ntawm peb hom ntawv nplooj ntawv, txhua yam yog daim ntawv sab saud, ntawv nruab nrab thiab ntawv qis.
Daim ntawv sab saud tseem hu ua daim ntawv rov qab-coated, thiab sab nraub qaum ntawm daim ntawv yog coated nrog microcapsules uas muaj Limin pigment oil; daim ntawv nruab nrab tseem hu ua pem hauv ntej thiab nram qab ob-coated ntawv, sab pem hauv ntej ntawm daim ntawv yog coated nrog cov xim tsim, thiab sab nraub qaum yog coated nrog Limin pigment roj. Microcapsules; daim ntawv qis tseem hu ua daim ntawv sab saum toj-coated, daim ntawv tsuas yog coated nrog tus tsim xim. Daim ntawv xim tus kheej yog coated nrog microcapsule txheej uas muaj Limin pigment roj nyob rau sab nraub qaum ntawm daim ntawv, thiab tus tsim xim thiab microcapsule uas muaj Limin pigment roj nyob rau sab pem hauv ntej. Muaj ob hom txheej txheej hauv cov ntawv tsis muaj carbonless: CF txheej nrog tus tsim xim thiab CB txheej nrog tus tsim xim. Tus neeg sawv cev chromogenic yog ib yam tshwj xeeb ntawm cov xim tsis muaj xim dyeing, uas tau yaj nyob rau hauv cov roj uas tsis muaj hluav taws xob thiab yog encapsulated los ntawm 3-7 μm microcapsules. Qhov cuam tshuam ntawm kev sau ntawv nyuaj thiab luam ntawv tuaj yeem cuam tshuam cov microcapsules, kom cov xim tsis muaj xim tsis muaj kuab paug ntws tawm thiab kov cov xim tsim tawm, ua rau cov tshuaj hloov pauv thiab qhia cov ntawv xim, kom ua tiav lub hom phiaj ntawm kev luam.
Raws li kev soj ntsuam kom muaj nuj nqis, carbon daim ntawv yog 45g / m2CB ntawv, 47g / m2CF daim ntawv thiab 52g / m2CFB ntawv, thiab lwm yam.; raws li cov xim ntawm daim ntawv, nws yog tsib lub ntsiab lus liab, daj, ntsuab, xiav, thiab dawb; Raws li cov xim cim qhia, nws yog xiav, daj, txiv kab ntxwv, dub, liab thiab lwm yam tones.
