Cov txheej txheem ntawm kev luam ntawv thiab sau ntawv tshuab suav nrog cov txheej txheem sib txawv uas ua rau tsim cov ntawv zoo siv rau ntau lub hom phiaj. Daim ntawv no yog ib qho tseem ceeb ntawm peb lub neej niaj hnub, nrhiav kev siv hauv kev kawm, kev sib txuas lus, thiab kev lag luam.
Cov txheej txheem ntawm kev luam ntawv thiab sau ntawv tshuab pib nrog kev xaiv cov khoom siv raw, feem ntau yog ntoo pulp lossis cov ntawv siv dua tshiab. Cov khoom siv raw yog pulped thiab tov nrog dej los tsim cov slurry, uas yog tom qab ntawd refined kom tshem tawm impurities thiab txhim kho qhov zoo ntawm pulp. Tom qab ntawd cov pulp refined yog pub rau hauv lub tshuab ntawv, qhov uas nws undergoes ib tug series ntawm cov txheej txheem xws li sib sau, nias, ziab, thiab txheej.
Nyob rau hauv txoj kev tsim ntawm lub tshuab ntawv, lub pulp yog kis mus rau ib tug tsiv hlau mesh, tso cai rau dej ntws thiab cov fibers los ua ke los ua ib daim ntawv txuas mus ntxiv. Daim ntawv ces dhau los ntawm cov xovxwm yob kom tshem tawm cov dej ntau dhau thiab txhim kho nws cov smoothness thiab uniformity. Tom qab nias, daim ntawv yog qhuav siv lub tog raj kheej-rhuab, kom tshem tawm cov seem ntawm cov dej noo thiab kev txhim kho ntawm nws lub zog thiab cov khoom nto. Thaum kawg, daim ntawv tuaj yeem ua cov txheej txheem txheej txheej los txhim kho nws cov ntawv luam tawm thiab cov tsos, nyob ntawm seb nws xav siv.
Kev siv luam ntawv thiab sau ntawv hauv lub neej txhua hnub yog ntau yam thiab tseem ceeb. Hauv kev kawm, nws yog siv rau phau ntawv kawm, phau ntawv ua haujlwm, thiab lwm yam ntaub ntawv kawm. Hauv ntiaj teb kev lag luam, nws yog siv rau cov ntawv sau, daim npav ua lag luam, cov ntawv ceeb toom, thiab lwm yam khoom siv sib txuas lus. Tsis tas li ntawd, luam ntawv thiab sau ntawv yog siv rau cov ntawv xov xwm, cov ntawv xov xwm, ntawv tshaj tawm, thiab lwm yam ntaub ntawv tshaj tawm, pab txhawb kev tshaj tawm cov ntaub ntawv thiab cov tswv yim.
Tsis tas li ntawd, luam ntawv thiab sau ntawv kuj yog siv rau kev sib txuas lus ntawm tus kheej, xws li cov ntawv, daim npav tos txais, thiab cov ntawv caw. Nws versatility thiab adaptability ua rau nws ib tug indispensable cuab tam rau kev xav, sib qhia cov ntaub ntawv, thiab khaws cia cov ntaub ntawv.
Hauv kev xaus, cov txheej txheem tsim cov tshuab luam ntawv thiab sau ntawv muaj cov txheej txheem nyuaj uas ua rau tsim cov ntawv zoo siv rau kev kawm, kev sib txuas lus, thiab kev lag luam. Nws cov ntawv thov hauv lub neej niaj hnub muaj ntau haiv neeg thiab qhov tseem ceeb, pab txhawb kev tshaj tawm cov ntaub ntawv, kev qhia cov tswv yim, thiab khaws cia cov ntaub ntawv. Kev tsim thiab siv tshuab luam ntawv thiab sau ntawv ua lub luag haujlwm tseem ceeb hauv peb lub neej txhua hnub thiab yuav ua li ntawd mus ntxiv rau yav tom ntej.
