Cov txheej txheem tsim khoom rau cov ntawv raj muaj ob peb kauj ruam. Ntawm no yog ib qho kev piav qhia dav dav ntawm yuav ua li cas cov hlab ntawv feem ntau tsim:
1.Paper Selection: Cov txheej txheem pib nrog xaiv hom ntawv tsim nyog thiab zoo rau daim ntawv thov uas xav tau. Yam xws li thickness, lub zog, thiab nto tiav yog xam raws li cov kev cai tshwj xeeb ntawm cov ntawv raj.
2.Cutting thiab Slitting: Cov ntawv xaiv yog ces txiav mus rau hauv ib daim hlab ntawm qhov xav tau dav thiab ntev. Cov txheej txheem txiav tuaj yeem ua tiav manually lossis los ntawm kev siv tshuab siv tshuab. Slitting tshuab kuj tseem siv tau los txiav cov ntawv dav dav rau hauv cov ntawv nqaim.
3.Gluing: Cov ntawv txiav strips yog coated nrog cov nplaum los yog kua nplaum raws lawv cov npoo. Cov kua nplaum pab khi cov ntawv txheej ua ke los ua ib lub raj ruaj khov. Ntau hom nplaum tuaj yeem siv tau nyob ntawm daim ntawv thov thiab xav tau lub zog ntawm daim ntawv raj.
4.Forming Lub Tube: Cov ntawv nplaum nplaum yog tom qab ntawd raug mob nruj nreem nyob ib ncig ntawm lub mandrel los yog daim ntawv, uas txiav txim siab lub puab txoj kab uas hla ntawm daim ntawv raj. Cov strips tau muab qhwv rau hauv cov qauv kauv, nrog rau txhua txheej sib tshooj me ntsis los tsim cov raj seamless.
5.Drying thiab Curing: Tom qab tsim lub raj, nws yuav dhau los ntawm cov txheej txheem ziab kom tso cai rau cov nplaum los teeb thiab khi cov khaubncaws sab nraud povtseg. Qhov no tuaj yeem ua tiav los ntawm huab cua kom qhuav lossis siv cov cua sov kom qhuav, nyob ntawm seb hom nplaum siv.
6.Cutting thiab Finishing: Thaum daim ntawv raj qhuav thiab kho, nws raug txiav mus rau qhov ntev ntev. Cov cuab yeej txiav precision yog siv los xyuas kom huv thiab raug txiav. Qhov kawg ntawm cov hlab ntsha tuaj yeem ua tiav nrog lub kaus mom, ntsaws, lossis cov khoom siv ntxiv raws li xav tau.
7.Txheej txheem txheej txheem ntxiv: Nyob ntawm qhov xav tau ntawm cov raj xa ntawv, cov txheej txheem ntxiv xws li luam ntawv, daim ntawv lo, lossis siv cov khoom tiav tuaj yeem ua tiav. Cov txheej txheem no txhim kho qhov tsos, kev tsim khoom lag luam, lossis kev ua haujlwm ntawm cov ntawv raj.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem tsim khoom tshwj xeeb rau cov raj xa ntawv tuaj yeem sib txawv nyob ntawm seb yam xws li qhov xav tau loj, tuab, thiab qhov nyuaj ntawm cov raj. Cov tuam ntxhab sib txawv tuaj yeem muaj lawv tus kheej hloov pauv thiab cov khoom siv xaiv los ua kom zoo dua qub thiab zoo.
