1. Cov khoom siv raw thiab ua ntej - ua
Cov ntawv sau tseg pov tseg yog cov khoom siv tseem ceeb, thiab nws cov kev hloov siab zoo ncaj qha cuam tshuam. Qhov tseem ceeb yog tsim los tsim cov txheej txheem txais txiaj ntsig tau.
Kev tshem tawm kev tawm tsam yuav tsum muaj txhij txhua. Lub xub ntiag ntawm cov ntaub ntawv txawv teb chaws xws li cov hlau ntim, zaj duab xis yas, thiab cov nplaum thiab cov ntsiab lus tsis sib xws thiab cov ntsiab lus sib luag thaum lub sijhawm molding theem.
Ua raws li cov khoom siv raw khoom siv. Ua ntej siv ntev - Cov ntaub ntawv fiber ntau xws li cov ntawv qub corrugated thiab ntawv nyeem fiber ntau. Zam kev sib xyaw ua ke nyob rau hauv luv -} Cov ntawv fiber ntau xws li coated ntawv lossis thermal ntawv.
Revolely tsis lees paub pwm lossis cov khoom siv tsis muaj kuab. Txawm hais tias nrog kev ua kom muaj zog, cov ntaub ntawv no tuaj yeem tuav cov kab mob me los yog cov tshuaj uas muaj tshuaj lom neeg.
2. Kev tswj yuam sij hauv pulping txheej txheem
Lub pulping theem yuav tsum tau mloog rau kev sib cais fiber ntau. Tshaj {- pulping puas fiber ntau, thaum tsis txaus sib cais tuaj yeem tsim cov pob fiber. Cov lus pom zoo:
Configure mult -} theem ntsuas ntsuas. Lub vijtsam tseem ceeb tsis suav cov ntawv, cov vijtsam lub zog theem nrab tshem tawm grit thiab hmoov av centrifugal screen canning nplaum nplaum.
Cov nqi tswj tsis xws sib xws yuav tsum ua kom them nyiaj ntau. Siv kev siv online zoo li qub rau tiag- Lub sijhawm cov ntaub ntawv tawm tswv yim kom ua tau kho cov dej dej dawb.
Kev ntxiv tshuaj ntxiv yuav tsum sib phim cov fiber ntau lub xeev. Kev ntxiv dag zog rau cov neeg sawv cev yuav tsum tau ntxiv tom qab cov fibers yog tag nrho o {{{} {ristist cov neeg sawv cev yog qhov zoo tshaj plaws sib xyaw ua ntej molding.
3. Txhim kho cov txheej txheem moulding txheej txheem
Tswj peb tus yuam sij thaum lub tshuab nqus hluav taws xob moulding:
Pulp Flow Velocity cuam tshuam fiber ntau orientation. Kev ntws ntau dhau ua rau cov Fiber ntau, txo qis radial lub zog.
Lub tshuab nqus tsev gradient yuav tsum ua raws li cov pib "qeeb {{}} rapt full" qauv tas li kom tsis txhob suthing ua rau muaj kev puas tsuaj rau pwm.
Pwm Mesh Xaiv yuav tsum txiav txim siab Fiber. Overly ntom mesh txhim kho nto smoothness tab sis txo cov dewatering efficiency.
4. Tseem ceeb ntawm kev ziab nkhaus tswj
Kom qhuav tsis yog tsuas yog dej evaporation; Nws yog ib theem tseem ceeb rau hydrogen khi tsim ntawm fibers.
Cov theem cua sov yuav tsum qeeb thiab khov kho. Kev kub kub sai nce tuaj yeem ua rau muaj kev sib dhos nto.
Theem nrug sov tas li yuav tsum ceev cia kom ntev rau cov dej ua ke ntawm cov fibers kom dim.
Tswj cov av noo noo thaum lub sijhawm txias kom tiv thaiv cov dej noo thiab deformation.
5. Kev tsom xam ntawm cov khoom tsis zoo ua rau
Countermeasures rau cov teeb meem zoo:
Ntau dhau ntug burrs feem ntau vim yog pwm coj los yog lub tshuab nqus tsev ntau dhau.
Cov lus txhais tsis tau muaj feem ntau tshwm sim los ntawm kev faib cov lus qhia tsis sib xws.
Tshooj kev sib tsoo feem ntau kav los ntawm cov fiber ntau pawg neeg quab yuam.
Muag ib puag ncig huab cua yuav tsum tau kuaj cov nyiaj emulsification ntawm cov dej -} Cov neeg sawv cev tiv thaiv.
6. Txheej Txheem Xyuas Kev Tswj Xyuas Khoom Siv
Tsim kom muaj tag nrho - txheej txheem zoo traceazorility mechanism:
Tsim cov ntaub ntawv fiber ntau rau cov ntaub ntawv raw, ntaub ntawv pawg thiab cov khoom pib.
Teeb tsa cov chaw kuaj xyuas kom xwm yeem, PE Nqi, thiab kev ntaus ntawv qib hauv pulping txheej txheem.
Ua Pwm Cev Tsis Txaus Ntshai Pauv kev ntsuam xyuas ntawm cov chaw nres tsheb moulding.
Ua raws li noo noo graphient qhia kev tshuaj xyuas qhov kawg ntawm cov kab ziab.
7. Cov Cuab Yeej Siv Khoom Siv
Ua kom muaj kev sib luag los ntawm cov cuab yeej ua ntej ntawm cov khoom siv:
Hloov pulper hniav hnav ua ntej tshaj qhov chaw ntau lawm.
Ua tiav txhua hli muab cov tshev ntawm cov tshuaj ntsuam lub tog raj kheej hluav taws xob.
Ua tib zoo mloog rau cov ntaub ntawv sib dhos thaum lub tshuab nqus tsev.
Nquag ua cov txheej txheem sib npaug sib npaug rau cov kiv cua kom qhuav.
8. Cov ntsiab lus cov ntsiab lus rau cov ntawv thov ntxiv
Cov hauv paus ntsiab lus rau kev siv cov kev sib ntxiv)
Kho cov tshuaj ntau npaum li cas ntawm kev ntxiv dag zog rau cov neeg sawv cev ntawm cov caij av noo.
Ntsuam xyuas cov emulsion ruaj khov ntawm txhua pob dej -}} tiv taus tus neeg saib xyuas.
Txau cov neeg sawv cev kom ua ib daim duab ua yeeb yaj kiab sib xyaw.
Xav txog qhov cuam tshuam rau lub zog fiber ntau thaum ntxiv zas.
9. Kev Txhim Kho Cov Qauv Txheej Txheem
Tsim kom muaj kev teb sai sai mechanism rau teeb meem:
Teeb tsa cov pulp nrawm nrawm sim ua haujlwm nrog cov fiber ntau analyzer.
Tsim cov txheej txheem ntsuas hluav taws xob ua kom pab tau zoo los ua cov kev sim ua tsis tu ncua.
Tsim cov ntaub ntawv txij nkawm xws li kev nrhiav cov kev pabcuam lub neej ntawm kev tshuaj ntsuam pwm.
Rov ua haujlwm cov txheej txheem kev ua haujlwm thiab siv dual - tus neeg pov thawj rau txoj haujlwm tseem ceeb.
Los ntawm kev tsim kho cov txheej txheem los ntawm cov khoom siv raw kom tiav cov khoom xa tawm, thiab tsom cov khoom ruaj khov, moulding ruaj khov - Cov khoom siv tau zoo, kev sib tw qe cuab. Hauv kev xyaum, tshwj xeeb mloog yuav tsum tau them nyiaj rau parameter txuam ntawm kev sib txuam ntawm cov txheej txheem. Tsim cov khaub lig - txheej txheem zoo li qhov txuas ntxiv txuas ntxiv kom txo qis kev hloov kho tag nrho.
