Kev tsim cov txheej txheem ntawm cov ntaub ntawv nyoos rau cov duab los qhia
1 Tus Qauv: Thawj kauj ruam ntawm kev tsim cov ntawv thiab cov ntawv zaub sawv yog tsim qauv. Cov tsim qauv ntawm cov tuam txhab ntawv yuav tsum muaj qhov kev xav zoo thiab yuav tsum paub txog kev ua haujlwm ntawm cov qauv ntawm peb-seem. Cov txheej txheem tsim xav tau ua ke nrog cov khoom, thiab qhov nyhav thiab qhov loj thiab cov khoom muag tau txiav txim siab los laij lub peev xwm nqa khoom thiab thaj chaw thaj tsam ntawm daim ntawv tso saib khib.
2 Cov Qauv: Daim ntawv tso duab khib feem ntau siv corrugated cardboard raws li cov khoom siv, thiab tawm tswv yim cov qauv tsim qauv cov ntaub ntawv rau hauv cov khoos phis tawj ntawm cov qauv txiav tshuab. Tus qauv txiav tshuab yog kev teeb tsa cov qauv ntawm lub zog indentation thiab ib nrab-txiav qhov tob uas yuav tsum tau los ntawm cov ntaub ntawv. Ua cov ntawv ntim ua qauv ua qauv dav hlau ntawm cov ntawv uas tsis muaj cov ntawv luam tawm, thiab tom qab ntawd tus tsim qauv siv cov kua nplaum thiab lwm cov txheej txheem los ua cov duab nraaj ua ib daim duab peb sab hauv cov duab saib.
3 Kev Luam Ntawv: Daim ntawv teeb duab rau cov ntawv luam yog ua tiav du thiab tsis muaj qauv. Cov tuam tsev tsim qauv tuaj yeem luam tawm cov ntawv luam tawm racks raws li cov neeg siv khoom xav tau, hais txog tus kheej thiab kev ntxim nyiam ntawm cov ntawv racks. Raws li daim ntawv thav ntawv (ntawv thaib ntawv thav duab thav duab) qauv tsim raws li cov duab nrawm, daim tseem yog luam tawm ntawm zaj duab xis ntawm lub tshuab luam ntawv
4 Kev ua tiav tom qab: xim ntawv dhau xim, ntawv dhau los (ntawv luam ntawv ntawv + ntawv corrugated), dhau roj, indentation.
5 Ntim: Tom qab sib sau ua ke thiab txhim kho cov ntawv ua tiav ib nrab ntawm cov ntawv ci tso saib, muab tso rau hauv cov khoom tiav ua tiav los qhia cov khoom muag.
Cov txheej txheem hauv qab no:
1: Txiav cov ntoo los ua cov khoom nyoos 2: Txiav kom ntev ntev 3: txiav cov tawv ntoo 4: Txiav rau cov nplais 5: Txiav rau hauv cov hlais 6: Sau cov hlais thiab thauj lawv mus rau ntawv zeb 7: Siv kua thiab ncu ua pulp 8: Siv tshuaj ntxuav dej nrog dej 9: Tshem tawm kom tsis txhob muaj teeb meem 10: Bleaching pulp 11: Tso tshuaj rau hauv lub plawv hniav 12: Muab dej nrog lub vas 13: Muab dej kom xav tias yuav nqus dej 14: Kom qhuav ntawm ya raws ntawm qhov kub 15: Calendering txheej txheem nrog tus calender 16: Ua ntawv yob
