Peb lub thawv ntawv lub tshuab ua tau raws li qhov yuav tsum tau muaj peev xwm ntau lawm thiab txuag hluav taws xob. Ntau qhov ntsuas ntawm daim ntawv tshaj qhov kev cia siab ntawm cov neeg siv khoom.
Daim Ntawv Tshuab Hlau Ntu
Nyob rau hauv ntub kawg ntawm daim ntawv tshuab zaum lub taub hau, uas faib ib tug niaj hnub dav hlau ntawm watery Tshuag. Cov kua dej poob rau ntawm cov hlau los yog cov ntaub ntawv. Hauv qab cov hlau, foils (luv luv rau hydrofoils) tshem tawm cov dej thiab txhim kho fiber ntau sib xws, kom ntseeg tau tias cov fibers weave ua ke hauv ib lub lev nruj. Cov hlau hla dhau lub thawv nqus dej uas nqus dej tawm, tawm hauv cov ntaub mos mos ntawm cov ntaub so ntswg uas ua rau daim ntawv, los yog lub vev xaib ntawv. Txog tam sim no cov hlau tau mus txog 30-40 meters. Hauv ob peb vib nas this, cov ntsiab lus dej tau poob mus rau 75-80 feem pua , thiab lub vev xaib tau poob nws cov ntaub ntub dej.
Daim Ntawv Tshuab Xovxwm Tshooj
Cov theem tom ntej ntawm kev tshem tawm dej yog dhau ntawm daim ntawv lub vev xaib los ntawm cov nip rollers uas nyem cov dej tawm ntawm lub pulp lev. Lub siab no kuj compresses cov fibers kom lawv intertwine los ua ib tug ntom, du daim ntawv. Nyob rau theem no, cov ntsiab lus dej tau txo mus rau ntawm 45 thiab 55 feem pua.
Daim Ntawv Tshuab Drying Tshooj
Daim ntawv lub vev xaib tam sim no taug kev los ntawm qhov chaw kaw uas muaj ntau lub tshuab ziab khaub ncaws kom qhuav. Lawv tau sov txog li 130ºC siv cov cua kub kom ntseeg tau tias daim ntawv tam sim no qhuav 80 mus rau 85 feem pua. Kev daws ntub dej tam sim no yog siv rau hauv daim ntawv txhawm rau ntxiv ib txheej nyias ntawm cov hmoov txhuv nplej siab rau saum npoo. Cov hmoov txhuv nplej siab pab txhawb kev nruj thiab kev sib txuas ntawm cov fibers hauv daim ntawv. Tom qab qhov sizing yog thov, daim ntawv hla mus rau lwm txheej ntawm rhuab kom qhuav lub tog raj kheej. Nyob rau hauv tag nrho, daim ntawv lub vev xaib tuaj yeem mus txog 400 meters los ntawm qhov kawg qhuav. Hauv cov txheej txheem, nws yuav poob li 93 feem pua ntawm nws cov dej.
