Tshuab Ua Ntawv Soj Ntsuam Siv cov ntawv pov tseg lossis ntoo pulp ua cov khoom siv raw, thiab cov ntawv pov tseg tsim cov ntawv so ntswg nruab nrab thiab qis; ntoo pulp tsim cov ntawv so ntswg zoo, daim ntaub so ntswg ntsej muag, daim ntaub phuam tes, thiab daim ntawv so ntswg. Cov txheej txheem tsim cov ntawv so ntswg suav nrog peb ntu: ntu pulping, ntu ua ntawv thiab ntu hloov ntawv.
1. Kev siv cov ntawv pov tseg, cov ntawv siv hauv chav dej siv cov phau ntawv pov tseg, cov ntawv ua haujlwm thiab lwm cov ntawv dawb pov tseg ua cov khoom siv raw, vim nws muaj cov yas yas, cov khoom siv staples, cov kua luam ntawv, feem ntau yuav tsum tau tawg, tshem tawm cov xim, tshem tawm cov slag, tshem tawm xuab zeb, tshuaj dawb, ua kom zoo thiab lwm yam txheej txheem ua tiav.
2. Kev ua cov ntoo pulp pulping, ntoo pulp yog hais txog cov ntoo pulp lag luam tom qab bleaching, uas tuaj yeem siv ncaj qha rau kev ua ntawv tom qab tawg, refining, thiab tshuaj ntsuam.
3. Lub tshuab ua ntawv, tshuab ua ntawv so quav muaj xws li ib feem, ib feem ziab, thiab ib feem dov. Raws li cov khoom sib txawv, nws muab faib ua lub tog raj kheej pwm hom tshuab ua ntawv so quav, nruab nrog MG Tshuab Ziab Khaub Ncaws lub tog raj kheej thiab lub tshuab dov ntawv ib txwm muaj, uas siv rau kev tsim cov peev xwm tso zis me me thiab nruab nrab thiab kev ua haujlwm ceev; lub tshuab ua ntawv so quav hom hlau nkhaus thiab hom crescent yog lub tshuab ntawv nrog cov thev naus laus zis tshiab hauv xyoo tas los no, nrog kev ua haujlwm ceev siab. Cov yam ntxwv ntawm lub peev xwm tso zis loj, txhawb nqa Yankee tshuab ziab thiab kab rov tav pneumatic ntawv dov.
4. Hloov cov ntaub so ntswg hauv chav dej, cov khoom tsim los ntawm lub tshuab ntawv yog jumbo yob ntawm cov ntawv hauv paus, uas yuav tsum tau ua ntau yam kev ua tiav kom tsim tau cov ntaub so ntswg uas xav tau, suav nrog cov ntaub so ntswg rewinding, txiav thiab ntim tshuab, tshuab phuam so tes, tshuab ntawv phuam, tshuab ntaub so ntswg ntsej muag.
