Nyob rau ib puag ncig thaum ib puag ncig kev paub tau nce zuj zus, daim ntawv thov thiab cov txheej txheem ntau lawm ntawm cov khoom siv hluav taws xob tau nyiam ntau.
Cov ntaub ntawv nyoos ntawm cov khoom siv hluav taws xob siv hluav taws xob feem ntau yog cov ntawv pov tseg. Ua ntej, sau ntau hom ntawv pov tseg khib nyiab, cartons, thiab tom qab cov ntaub khib nyiab suav, thiab cov hlau raug tshem tawm kom ntseeg tau tias qhov kev ua kom huv si.
Tom ntej no yog tus txheej txheem pulping. Daim ntawv pov tseg khib nyiab yog tawg rau hauv cov tshuaj lom. Cov txheej txheem no feem ntau siv cov khoom siv tawg tshwj xeeb los ua kom tiav cov khib nyiab ib leeg los ntawm kev siv hluav taws xob thiab dej. Tom qab ntawd, lub puab tsaig tawg yuav raug tshuaj ntsuam thiab ua kom huv kom ua ntxiv tshem tawm cov khoom tsis zoo thiab ua kom zoo rau lub sam xeeb.
Nyob rau hauv lub sam thiaj, qee cov tshuaj ntxiv tshuaj ntxiv yuav raug ntxiv raws li cov kev xav tau. Piv txwv li, txhawm rau txhim kho lub zog ntawm lub thawv pulp, tus nqi tsim nyog yuav raug ntxiv; Txhawm rau kho cov pH tus nqi ntawm pulp, qee cov kua qaub-hauv paus yuav siv tau. Qhov no tuaj yeem ua kom ua kom tiav qhov kev ua tau zoo ntawm lub sam thiaj thiab ua rau nws haum rau kev ua cov thawv pulp.
Tom qab ntawd los cov txheej txheem moulding. Lub samp no tau nias thiab moulded siv cov pwm los ua cov qauv ntawm lub thawv pulp. Tus txheej txheem no yuav tsum tau kho cov txheej txheem ntau yam xws li kev tswj hwm lub zog thiab siv lub sijhawm kom ntseeg tau thiab zoo ntawm lub thawv pulp.
Lub thawv puab rau cov thawv los kuj yuav tsum tau qhuav kom tshem tawm cov ya raws hauv nws kom nws mus txog qhov tsim nyog noo noo cov ntsiab lus. Lub thawv lim dej qhuav yuav tseem tuaj yeem dhau los ua tom qab ua, xws li txiav thiab luam ntawv, kom tau raws li kev xav tau zaum kawg lossis siv cov cai zaum kawg lossis siv cov cai kawg.
Txoj kev tsim khoom ntawm cov khoom siv hluav taws xob muaj zog muaj ntau yam zoo. Nws tsis tuaj yeem siv cov khoom siv pov tseg zoo siv thiab txo cov kuab paug rau ib puag ncig, tab sis kuj txo cov nqi tsim khoom. Nrog kev txhim kho txuas ntxiv ntawm cov kev tiv thaiv ib puag ncig, kev nce qib thiab cov thawv siv hluav taws xob yuav ua lub luag haujlwm tseem ceeb hauv ntau daim teb.
