Cov txheej txheem ntim cov ntawv ntim khoom suav nrog hloov cov ntawv pov tseg- dhau ntawm cov txheej txheem txheej txheem - rau hauv cov ntaub ntawv uas tsim nyog rau lub hom phiaj ntim. Cov hauv qab no yog cov lus piav qhia luv luv ntawm cov txheej txheem tsim khoom siv rau cov ntawv ntim khoom:
1. Raw Material Preparation: Ntau hom ntawv pov tseg-xws li ntawv xov xwm, thawv ntawv, thiab lwm yam.-sau, txheeb, thiab cais tawm kom tshem tawm cov impurities. Nyob rau tib lub sijhawm, ib qho dej huv uas tsim nyog ntxiv rau hauv daim ntawv pov tseg kom soften thiab moisten nws.
2. Shredding thiab Disintegration: Cov ntaub ntawv softened yog pub rau hauv ib lub shredder los yog pulper rau kev sib tsoo thiab disintegration, rhuav nws mus rau hauv lub xeev fibrous thaum tib lub sij hawm tshem tawm cov number case thiab lwm yam kab mob.
3. Kev Npaj Pulp: Cov fibers disintegrated yog tov nrog dej thiab nplawm kom huv si los ua ib tug pulp slurry. Qhov concentration ntawm cov pulp thiab qhov ntev ntawm cov fibers tuaj yeem hloov kho raws li cov khoom siv tshwj xeeb.
4. Pulp Refining: Lub pulp yog pub rau hauv ib lub refiner, qhov uas nws undergoes siab - ceev agitation thiab soj ntsuam kom tshem tawm cov seem impurities thiab coarse fibers, yog li txhim kho tag nrho cov zoo thiab fibrous qauv ntawm lub pulp.
5. Daim Ntawv Tshuab Sib Sau: Cov ntawv ntim tau muab tso rau hauv daim ntawv- ua tshuab; Siv qhov kev txiav txim ntawm cov ntxaij vab tshaus thiab lub tshuab nqus tsev nqus, cov dej hauv cov ntaub so ntswg maj mam rub tawm, tso cai rau cov fibers los cuam tshuam thiab tsim ib daim ntawv txuas ntxiv ntawm qhov screen.
6. Qhuav thiab Calendering: Cov ntawv tsim tshiab dhau los ntawm cov khoom siv ziab, qhov chaw nws cov dej noo maj mam evaporates, ua rau daim ntawv qhuav. Tom qab ntawd, daim ntawv hla dhau lub tshuab calender kom nws nto smoother thiab flatter.
7. Winding thiab Txiav: Cov ntawv qhuav yog ua tiav los ntawm lub tshuab winder kom dov rau hauv cov reels loj, los yog txiav rau hauv cov ntawv tiaj tus. Cov hom ntawv tshwj xeeb nyob ntawm qhov yuav tsum tau ua thiab specifications ntawm cov khoom kawg.
8. Ntim thiab Kev Tshuaj Xyuas Zoo: Cov ntawv reels lossis cov ntawv ntim tau ntim rau tib lub sijhawm kev tshuaj xyuas zoo kom paub tseeb tias cov khoom xws li thickness, lub zog, thiab gloss ua tau raws li cov qauv xav tau.
9. Warehousing and Shipping: Cov khoom tiav cov ntawv pov thawj raug xa mus rau ib lub tsev rau khoom cia thiab tom qab ntawd ntim thiab xa tawm raws li kev txiav txim tshwj xeeb.
