Muaj ntau cov tshuaj ntxiv rau kev ua ntawv feem ntau siv rau hauv kev lag luam ntawv, thiab lawv cov ntau yam yog dav thiab siv dav, thiab lawv cov haujlwm feem ntau yog cuam tshuam rau hauv cov hauv qab no:

01 Txhim kho kev ua haujlwm kom zoo dua qub

Yuav kom txhim kho qhov ceev ntawm qhov kawg ntub ntawm lub tshuab ntawv dewatering thiab ua kom cov dej hauv lub cadre evaporation sai dua, cov khoom siv lim dej tuaj yeem ntxiv los txhim kho kev ua haujlwm ntau lawm. Yuav kom ua rau cov pulp stain sib npaug thiab ruaj khov, mordant thiab dispersant tuaj yeem ntxiv. Thaum ntsuas rosin, ntxiv synergist tuaj yeem txhim kho qhov cuam tshuam ntawm qhov loj me. Ntxiv mus, cov ntawv pov tseg rov ua dua tshiab muaj cov kua mem thiab lwm yam khoom, thiab cov neeg sawv cev deinking ntawv pov tseg tuaj yeem ntxiv los tsim cov pulp ntshiab.

02 Txhim kho qhov zoo thiab muab cov khoom tshwj xeeb rau daim ntawv

Piv txwv li, daim ntawv cement hnab xav tau lub zog siab thiab permeability zoo, thiab qib ntaus tsis tuaj yeem siab thaum ntaus. Yuav kom txhim kho lub zog ntawm daim ntawv, cov neeg sawv cev qhuav feem ntau ntxiv. Cov ntaub so ntswg thiab cov phuam ntawv yuav tsum mos li paj rwb, thiab cov ntaub so tsis tuaj yeem ua rau tawg, thiab yuav ntxiv cov tshuaj ua kom daim ntawv mos.

03 Txo cov khib nyiab thiab txuag cov khoom siv raw

Piv txwv li, ntxiv cov neeg sawv cev khaws cia thiab flocculants rau hauv pulp tuaj yeem txhim kho qhov ceev ntawm kev khaws cia ntawm cov khoom sau thiab cov fibers zoo, txo qhov poob, txuag cov khoom siv raw, thiab txo cov dej khib nyiab.

04 Tshem tawm cov teeb meem kev tsim khoom

Thaum lub caij ntuj sov, av nkos feem ntau muaj nyob rau hauv cov thoob dej av nkos, cov thoob dej mesh, lossis cov kav dej dawb thiab lwj, tsim kev cuam tshuam rau kev tsim khoom. Tam sim no muaj ntau yam kev ua haujlwm siab, tsis muaj tshuaj lom, cov tshuaj preservatives uas lwj nws tus kheej, tuaj yeem tua cov kab mob thiab tiv thaiv xeb, yuav tsis ua rau muaj kuab paug.

Yog tias cov pulp tsis raug ntxuav thiab sib xyaw nrog huab cua, nws yuav tsim cov ua npuas ncauj thiab cov pulp ntab, uas ua rau muaj kev phom sij rau qhov zoo thiab kev ua haujlwm ntawm daim ntawv. Txhawm rau kom tshem tawm qhov kev puas tsuaj ntawm cov ua npuas ncauj, cov tshuaj defoamer thiab cov neeg sawv cev degassing tuaj yeem siv.

05 Txhim kho kev ua haujlwm ntau lawm

Kev siv cov tshuaj ntxuav pam tuaj yeem ua rau kev ntxuav pam sai dua thiab ua kom pam huv si. Cov nplaum feem ntau raug ntxiv rau cov txheej txheej kom txhim kho qhov zoo ntawm cov ntawv txheej. Kev ntxiv cov tshuaj dispersant tuaj yeem txo qhov viscosity ntawm cov txheej, txhawb kev ua haujlwm ntau lawm thiab ua rau cov txheej sib xws. Kev ntxiv cov nplaum tuaj yeem txhim kho qhov tsis kam dej ntawm cov txheej.
