Kev luam ntawv dawb rau ntawm daim ntawv kraft tuaj yeem yog txoj kev nyuaj, thiab muaj ntau yam laj thawj rau qhov nyuaj no:

1. Absorbency: Kraft daim ntawv yog cov khoom siv absorbent heev, uas txhais tau hais tias nws nyiam nqus cov number case sai.Qhov no tuaj yeem ua rau nws nyuaj rau kev ua tiav cov txheej txheem sib xws thiab opaque ntawm cov xim dawb ntawm daim ntawv, vim tias tus number case yuav nqus tau rau hauv cov fibers ntawm daim ntawv ua ntej nws muaj sijhawm kom qhuav.Nws feem ntau tshwm sim tias qhov whiteness tsuas yog tom qab luam ntawv yog ze txaus rau tus number case dawb.Sij hawm dhau mus, tus number case dawb yog maj mam nqus los ntawm daim ntawv kraft, thiab cov xim ntawm tus number case dawb yuav ploj mus.Lub degree ntawm kev nthuav qhia ntawm cov nyhuv tsim yog txo qis heev.
2. Kev ntxhib los mos: Kraft daim ntawv muaj qhov ntxhib thiab ntxeem tau zoo nkauj, uas tuaj yeem ua rau nws nyuaj rau tus cwj mem dawb kom ua raws li qhov chaw ntawm daim ntawv.Qhov no tuaj yeem ua rau cov ntawv luam tawm tsis zoo lossis tsis sib xws, vim tias tus number case yuav tsis tuaj yeem sib npaug sib npaug ntawm daim ntawv.
3. Xim: Lub ntuj xim ntawm kraft ntawv yog lub teeb xim av los yog xim tan, uas tuaj yeem cuam tshuam cov xim dawb thaum nws luam tawm ntawm daim ntawv.Cov xim ntuj ntawm daim ntawv tuaj yeem muab cov cwj mem dawb xim daj lossis xim av xim av, uas tuaj yeem cuam tshuam los ntawm lub ntsej muag, huv si uas feem ntau xav tau hauv cov ntawv luam ntawv dawb.
4. Ink formulation: Cov qauv ntawm cov number case dawb tuaj yeem cuam tshuam nws lub peev xwm los ua raws li kraft ntawv.Qee hom xim dawb yuav tsim nyog siv rau ntawm daim ntawv kraft dua li lwm tus, nyob ntawm lawv cov viscosity, xim xim, thiab lwm yam.

Txhawm rau daws cov teeb meem no, muaj ntau txoj hauv kev uas tuaj yeem siv los txhim kho qhov zoo ntawm cov ntawv luam ntawv dawb ntawm kraft ntawv.Piv txwv li, cov tshuab luam ntawv yuav siv tus cwj mem dawb denser uas muaj cov xim ntau dua ntawm cov xim, uas tuaj yeem pab xyuas kom meej tias tus number case tseem opaque thiab vibrant ntawm daim ntawv.Lawv kuj tuaj yeem siv lub vijtsam mesh siab dua thaum luam ntawv, uas tuaj yeem pab txo tus lej ntawm tus lej uas tau nqus rau hauv daim ntawv.Tsis tas li ntawd, cov tshuab luam ntawv tuaj yeem siv cov txheej txheem ua ntej kev kho mob uas suav nrog kev siv cov txheej txheem los yog primer rau saum npoo ntawm daim ntawv ua ntej luam ntawv, uas tuaj yeem pab txhim kho qhov adhesion ntawm tus number case rau saum npoo ntawm daim ntawv.

Hauv cov ntsiab lus, luam ntawv tus cwj mem dawb rau ntawm daim ntawv kraft tuaj yeem yog cov txheej txheem nyuaj vim qhov absorbency, kev ntxhib los mos, xim, thiab number case formulation ntawm daim ntawv.Txawm li cas los xij, los ntawm kev siv cov txheej txheem tshwj xeeb thiab cov ntaub ntawv, cov tshuab luam ntawv tuaj yeem ua tiav cov txiaj ntsig zoo thiab pom cov ntawv luam tawm ntawm cov ntawv kraft.

SIUMAI ntim siv dawb UV number case rau kraft ntawv ntim luam ntawv.Tus number case yog kho los ntawm UV lub teeb thaum nws txuas nrog rau daim ntawv.Nws loj heev tiv thaiv kraft ntawv los ntawm absorbing number case.Tshaj tawm cov duab kos duab ntawm kev tsim qauv zoo dua nyob rau pem hauv ntej ntawm cov neeg siv khoom.Peb tau sau cov kev luam ntawv nplua nuj rau kev luam ntawv dawb ntawm kraft ntawv.Zoo siab txais tos cov neeg muas zaub tuaj sab laj.
