Nyob rau hauv lub sijhawm niaj hnub no ntawm kev nrhiav kev tiv thaiv ib puag ncig thiab kev nrhiav khoom ntim tau zoo li cov khoom lag luam ntsuab tau muaj ntau txoj kev tseem ceeb.
Ua ntej tshaj plaws, kev xaiv ntawm cov khoom siv raw yog qhov tseem ceeb heev. Cov ntaub ntawv ntim kom ntev tsuas yog los ntawm cov khoom siv ntoo txuas ntxiv lossis cov ntawv pov tseg. Tsob ntoo ntuj yuav tsum yog kom muaj kev ntseeg tau los ntawm cov hav zoov zoo thiab ua raws cov ntsiab cai ntawm kev ua kom muaj kev deb ntawm cov chaw ua haujlwm txuas ntxiv ntawm cov hav zoov cov peev txheej. Kev siv cov ntawv luam tawm tuaj yeem txo qis cov av pov tseg thiab qhov kev thov rau nkauj xwb fiber ntau, thiab paub txog kev rov ua dua tshiab.
Nyob rau hauv lub sam thiaj, siv cov txuj ci siab thev naus laus zis yog tus yuam sij los ua kom muaj kev ua tau zoo ntawm purp. Txawm hais tias tshuaj lom neeg chemical tuaj yeem cais cais cov fibers, nws yuav ua rau muaj cov teeb meem papution ib puag ncig. Yog li ntawd, ntau ntxiv kom siv cov neeg kho mob pulping los yog roj ntsha lim cov hau kev. Txhua yam pulping so fibers los ntawm lub cev txhais tau tias, uas tuaj yeem zoo dua khaws lub zog ntawm cov fibers; Kev txheeb xyuas roj ntsha kev siv cov kab mob me los decompose lignin thiab cais cov fibers, uas yog ib puag ncig ntau ib puag ncig.
Ntxiv tus nqi tsim nyog ntawm cov tshuaj sib ntxiv tseem yog qhov tseem ceeb ntawm cov khoom sib xyaw ntawm kev ruaj ntseg ntawm pulp ntim ntim ntim. Piv txwv li, nyob rau hauv thiaj li yuav txhim kho cov dej tsis kam ntawm pulp, qee qhov ntuj hydrophibic cov neeg sawv cev xws li siv quav ciab lossis zaub cov roj ua qe tuaj yeem ntxiv. Txog ntim uas yuav tsum muaj qee lub zog, ib qho me me ntawm cov neeg nyiam ib puag ncig cov nplaum muaj peev xwm ntxiv tau ntxiv txoj kev sib khi.
Tsis tas li ntawd, kev siv tshuab moulding thiab ua cov thev naus laus zis ntawm pulp kuj cuam tshuam rau kev ua tau zoo ntawm cov khoom ntim ntim kawg. Los ntawm kev kawm tau cov khoom siv tsim nyog siv cov cuab yeej siv thiab thev naus laus zis, ntim cov khoom lag luam ntawm ntau cov duab thiab ntau thiab tsawg tuaj yeem tsim tawm. Nyob rau tib lub sijhawm, thaum lub sijhawm ua, tsis ntsuas xws li kub thiab siab yog nruj me ntsis tswj kom ntseeg tau tias qhov muaj kev ruaj ntseg ntim.
Hauv ntej, cov qauv sib xyaw ntawm cov ntaub ntawv ntim kom ruaj khov cuam tshuam nrog ntau yam xws li kev xaiv raw, polping thev naus laus zis, kev siv ntxiv, thiab kev yoog ua. Los ntawm kev ua kom zoo thiab tsim kho tshiab, nws tuaj yeem ua tau zoo dua ntsib kev tiv thaiv ib puag ncig thiab kev xav tau ntim khoom.
