Daim ntawv ua tshuab

Khoom siv npaj
Nws yog cov khoom siv ua ntej kho thiab ua cov ntaub ntawv raw cov ntaub ntawv raws li qhov yuav tsum tau ua ntawm steaming lossis sib tsoo txheej txheem ua ntej steaming lossis sib tsoo. Nws tau muab faib ua cov khoom siv tsis yog ntoo fiber ntau thiab cov khoom siv ntoo fiber ntau npaj. Cov yav tas muaj xws li nyom cutters, reed cutters, thiab qab zib pulp tshem tawm, thaum tom kawg muaj xws li peelers, slicers, thiab hais txog.
Chiping tshuab yog lub tshuab uas txiav cov ntoo nyoos uas yuav tsum tau ua cov ntoo ntoo rau hauv cov ntoo chips ntawm ib qho tshwj xeeb, muab faib ua ob hom: disc thiab nruas; Steaming thiab boiling khoom yog ib yam khoom uas dissolves lignin nyob rau hauv papermaking raw cov ntaub ntawv rau ua noj ua haus kua, cais papermaking raw cov ntaub ntawv mus rau hauv fibers. Nws muab faib ua ob hom: sib tshuam thiab txuas ntxiv; Lub tshuab ntoo yog cov khoom siv los tsim cov ntoo hauv av, uas tuaj yeem muab faib ua ob hom raws li cov txheej txheem ntau lawm: sib tshuam thiab tsis tu ncua. Nws kuj tseem tuaj yeem muab faib ua ob hom raws li cov txheej txheem pressurization ntawm cov cav: hydraulic pressurization thiab mechanical pressurization;
Cov khoom siv pulping
Nws yog ib qho cuab yeej siv nyob rau hauv cov txheej txheem ntawm kev sib cais cov nroj tsuag raw cov ntaub ntawv rau hauv fibers. Cov txheej txheem pulping tuaj yeem muab faib ua cov txheej txheem tshuaj, kev siv tshuab, thiab cov txheej txheem chemical mechanical. Cov khoom siv pulping muaj xws li steamers, wood mills, thermal grinders, pulp wash machines, bleaching machines, pulping machines, and waste liquid recovery equipment.
Lub pulp tsim los ntawm slicing ntoo thiab preheat nws nrog chav ua ntej sib tsoo nws nyob rau hauv siab yog hu ua kub ntoo pulp. Lub tshuab siv los tsim cov ntoo kub kub yog lub tshuab thermal, uas siv hluav taws xob ntau heev. Yog li ntawd, tag nrho siv lub zog hluav taws xob thaum lub sij hawm sib tsoo yog qhov teeb meem tseem ceeb rau thermal mills; Lub tshuab ntxhua khaub ncaws yog cov cuab yeej siv tshuab uas sib cais cov kua txiv hmab txiv ntoo los ntawm cov cawv dub. Raws li tus nqi rho tawm ntawm cov cawv dub, muaj ob pawg: siab concentration thiab qis concentration extraction.
Lub hom phiaj ntawm cov kua txiv hmab txiv ntoo yog tshem tawm cov residual lignin thiab pigments los ntawm cov ntaub so ntswg tom qab ua noj, txhim kho cov tawv nqaij ntawm cov tawv nqaij, thiab muab cov xim dawb huv. Lub tshuab bleaching yog cov cuab yeej siv tshuaj dawb, uas muaj cov khoom siv xws li tshuaj dawb lub tank ntsia hlau kiv cua thiab lub nruas ntxhua. Lub pulp thiab tshuaj dawb yog muab tso rau hauv lub pas dej ua ke thiab txuas ntxiv nrog dej ntxuav. Nrog kev pab los ntawm ib tug ntsia hlau propeller, lawv circulate nyob rau hauv lub pas dej ua ke kom tiav cov txheej txheem ntawm kev sib tov thiab tshuaj tiv thaiv. Cov dej uas muaj cov khoom siv tshuaj dawb thiab cov tshuaj bleaching residual yog tawm los ntawm cov kab noj hniav sab hauv ntawm lub nruas ntxuav kom tau cov xim dawb huv.
tshuab ntawv
Nws yog ib qho ua tiav ntawm cov khoom siv uas ua kom muaj kev sib cais thiab kev sib txuas ntawm cov ntaub so ntswg rau hauv cov ntawv webs, nrog rau cov chav tseem ceeb xws li lub thawv ntws, lub tshuab mesh, lub tshuab nias, lub tshuab ziab khaub ncaws, lub tshuab ziab khaub ncaws, daim ntawv winding tshuab, thiab lub tshuab xa hluav taws xob, nrog rau cov khoom siv xws li chav dej, dej, lub tshuab nqus tsev, lubrication, thiab cua sov rov qab. Lub vev xaib uas tsim cov ntawv ntub dej lub vev xaib yog lub hauv paus ntawm lub tshuab ntawv, yog li lub tshuab ntawv tuaj yeem muab faib ua lub web ntawv ntev, clamped web paper machine, thiab ncig lub web paper machine raws li cov qauv ntawm lub vev xaib.
Lub thawv slurry yog ib qho khoom siv sib npaug thiab ruaj khov xa cov slurry ntawm qhov tsim nyog rau daim phiaj los ntawm cov khoom xws li cov khoom siv slurry, rectifier device, weir tank, thiab weir phaj nozzle, tseem hu ua lub thawv pem hauv ntej; Tom qab cov slurry yog txau los ntawm lub thawv slurry mus rau tooj liab mesh, nws tsim cov ntawv ntub dej ntawm lub mesh thiab ua rau lub cev qhuav dej; Tom qab ntawd, muaj kev nias, uas siv cov cuab yeej siv los nyem tawm cov dej noo los ntawm cov ntawv ntub dej los ntawm cov mesh, txhim kho cov dryness ntawm daim ntawv, thiab tib lub sij hawm, txhim kho cov khoom nto ntawm daim ntawv, tshem tawm cov cim mesh, thiab ua kom smoothness, nruj, thiab lub zog; Tom qab ntawd nws nkag mus rau hauv ntu kom qhuav kom lub cev qhuav dej ntxiv rau cov ntaub ntawv ntub dej tom qab nias, ua rau cov nplooj ntawv kom qis, ua rau cov fiber ntau sib txuas thiab muaj zog ntxiv.
Tom qab tau compressed los ntawm lub calender, cov ntawv los ntawm lub tshuab ziab khaub ncaws tuaj yeem txhim kho qhov smoothness, glossiness, thiab nruj ntawm daim ntawv los xij, ua rau lub thickness ntawm tag nrho cov ntawv zoo ib yam thiab txo cov huab cua permeability; Thaum kawg, daim ntawv lub vev xaib yog dov rau hauv daim ntawv yob los ntawm daim ntawv yob lub tshuab, ua tiav cov txheej txheem tseem ceeb ntawm papermaking. Yuav kom ua tau raws li cov kev xav tau sib txawv yav tom ntej, kuj tseem muaj super calenders, rewinding tshuab, ntawv txiav, thiab lwm yam. ntsia tom qab ntawv winding tshuab hauv daim ntawv rhiav.
Kev lag luam ntawv siv ntau cov khoom siv raw, dej, hluav taws xob, thiab tshuaj lom neeg, thiab tsim cov dej khib nyiab ntau thiab cov khoom pov tseg. Yog li ntawd, lub neej yav tom ntej ntawm papermaking machinery yuav txhim kho mus rau kev siv dav siv papermaking raw cov ntaub ntawv, txo cov khoom thiab lub zog noj nyob rau hauv cov txheej txheem papermaking, thiab minimizing ib puag ncig muaj kuab paug.
