Cov txheej txheem tsim khoom ntawm kraft daim ntawv ntim cov thawv feem ntau suav nrog ntau cov kauj ruam uas yog tsom rau kev tsim cov khoom muaj zog, ruaj khov, thiab eco-friendly ntim.Nov yog cov kauj ruam tseem ceeb hauv kev tsim kraft ntawv ntim thawv:

Pulping:Thawj kauj ruam yuav tsum tau pulping ntoo chips los yog recycled ntawv nyob rau hauv dej los tsim ib tug pulp sib tov.Qhov kev sib tov no yog tom qab ua kom zoo kom tawg cov fibers thiab tshem tawm impurities.

Papermaking:Lub pulp sib tov yog ces kis tawm nyob rau hauv ib tug nyias txheej ntawm ib tug hlau mesh thiab dej yog muab tshem tawm los ntawm ib tug series ntawm rollers thiab rhuab kom qhuav lub tog raj kheej.Cov txheej txheem no tsim ib qho txuas txuas ntxiv ntawm kraft ntawv.

Corrugation:Rau kev tsim corrugated kraft ntawv, daim ntawv yog dhau los ntawm ib tug series ntawm corrugating rollers uas ntxiv ib wavy txheej nyob rau hauv nruab nrab ntawm ob txheej ntawm daim ntawv tiaj tus, tsim ib daim ntawv peb-txheej.

Kev luam ntawv:Cov ntawv kraft tuaj yeem luam tawm nrog ntau yam qauv tsim, logos, lossis cov ntaub ntawv khoom siv siv tshuab luam ntawv uas siv number case rau daim ntawv.

Tuag txiav:Cov ntawv kraft yog txiav rau hauv cov duab tshwj xeeb thiab qhov ntau thiab tsawg siv cov tshuab txiav tuag.Cov kauj ruam no npaj cov ntawv yuav tsum tau muab tais thiab sib sau ua ke rau hauv cov khoom ntim khoom zaum kawg.

Folding thiab gluing:Cov ntawv txiav kraft yog ces muab tais rau hauv cov duab uas xav tau siv lub tshuab folding, thiab ua ke ua ke siv cov kua nplaum kub yaj los yog cov kua nplaum dej.Cov txheej txheem no tsim qhov kawg kraft ntawv ntim lub thawv.

Kev tswj kom zoo:Thoob plaws hauv cov txheej txheem tsim khoom, kev tswj xyuas zoo tau ua tiav los xyuas kom meej tias cov thawv ntawv kraft ua tau raws li cov qauv tsim nyog rau lub zog, ua haujlwm ntev, thiab ua tiav.

Cov kauj ruam saum toj no yog cov theem tseem ceeb koom nrog hauv kev tsim khoom ntawm kraft ntawv ntim thawv.Nws yog tsim nyog sau cia tias cov txheej txheem yuav txawv nyob ntawm seb cov khoom tsim tshwj xeeb thiab cov kev xav tau ntau lawm.
