Cov txheej txheem txheej txheem thiab cov yam ntxwv ua haujlwm
Lub tshuab nqus tsev thermoforming txheej txheem yog feem ntau nyob ntawm qhov tsis zoo siab adsorption. Cov khoom lag luam feem ntau yog khaws cia ntawm thaj tsam li 1%. Kev sib txawv ntawm qhov kev xav no, txawm tias siab dua lossis qis dua, tuaj yeem cuam tshuam rau fiber ntau faib uniformity.
Tom qab cov pwm tso rau hauv slurry, lub tshuab nqus tsev ua haujlwm, tsim kom muaj qhov tsis zoo ntawm qhov chaw nyob hauv cov pwm kab noj hniav. Fibers migrate thiab accumulate nyob rau hauv txoj kev hlau nto vim lub siab sib txawv. Kev tswj kom ruaj khov ntawm lub tshuab nqus tsev kawm ntawv, feem ntau khaws cia nyob ib ncig ntawm 520 Pa, yog qhov tseem ceeb thaum lub sijhawm no.
Cov txheej txheem dewatering muaj ob theem tseem ceeb: pib lub tshuab nqus tsev dewatering thiab tom qab siv tshuab nias. Thaum cov fiber ntau deposition mus txog lub thickness predetermined, cov pwm raug tshem tawm ntawm lub vat. Sab sauv thiab sab pwm kaw rau nias dewatering. Nyob rau theem no, compressed cua siab ntawm kwv yees li 0.2 MPa yog siv los txo cov khoom cov dej noo mus rau thaj tsam ntawm 65% -75%. Thaum kawg, kev ua haujlwm demolding yog ua tiav siv lub tshuab pneumatic.

Cov Ntsiab Cai Tswjfwm
Fiber deposition ceev yog cuam tshuam los ntawm ntau yam. Cov no suav nrog hom fiber ntau raw khoom, qib ntawm refining, qib ntawm lub tshuab nqus tsev, thiab cov khoom kub.
Lub sij hawm voj voog ntau lawm txawv heev raws li cov qauv khoom. ntiav, nyias-cov khoom siv phab ntsa zoo li cov tais qe lossis cov txiv hmab txiv ntoo pads feem ntau tsuas yog siv sijhawm 10-15 vib nas this xwb.
Sib sib zog nqus-kos, tuab- cov khoom siv phab ntsa yuav tsum tau ua raws li cov voj voog ntev dua. Lub sijhawm tshwj xeeb yuav tsum tau txiav txim siab los ntawm kev sim cov txheej txheem.
Tshuag kub ncaj qha cuam tshuam fiber ntau dispersion. Nws yog feem ntau tswj nyob rau hauv thaj tsam ntawm 35-45 degree.
Lub tshuab nqus tsev ruaj khov plays lub luag haujlwm txiav txim siab kom ua tiav cov khoom sib xws.
Cov cuab yeej ua haujlwm yam ntxwv
Lub tshuab nqus tsev yuav tsum muaj kev ruaj ntseg tsis zoo nyob ib puag ncig. Nyob rau hauv kev xyaum, lub tshuab nqus tsev twj tso kua mis feem ntau siv ib tug parallel configuration. Qhov no ua kom cov khoom lag luam txuas ntxiv tsis cuam tshuam yog tias ib chav ua tsis tiav.
Lub tshuab cua siab feem ntau ua haujlwm ob txoj haujlwm: pwm clamping / nias thiab demolding. Kev teeb tsa siab xav tau kev suav meej raws li cov khoom lag luam qhov projected cheeb tsam.
Hauv kev tsim pwm, kev xaiv mesh suav rau kev tsim cov hlau yog qhov tseem ceeb. Cov mesh ntau dhau impedes dewatering efficiency, thaum overly sparse mesh ua rau fiber ntau poob. Feem ntau, tsim cov xov hlau nyob hauv thaj tsam ntawm 80-120 mesh raug xaiv raws li qhov ntev ntawm fiber ntau.
Product Applicability Analysis
Txoj kev no yog tshwj xeeb tshaj yog tsim rau cov khoom tsim nrog qhov tob tob thiab cov phab ntsa tuab. Piv txwv muaj xws li cov khoom ntim txhua hnub xws li cov tais qe, cov txiv hmab txiv ntoo cushioning pads, thiab cov tais diav. Cov khoom no qhia cov yam ntxwv zoo ib yam: cov qauv yooj yim, cov duab cua loj loj, thiab tsis tas yuav muaj kev ua haujlwm thib ob.
Rau qhov sib sib zog nqus-cov khoom siv hauv kab noj hniav, yuav tsum tau saib xyuas tshwj xeeb rau fiber ntau deposition uniformity. Hauv kev xyaum, txoj hauv kev zoo li daim ntawv thov nqus tsev vacuum los yog kho cov khoom txaus feem ntau yog siv los txhim kho fiber ntau hauv cov ces kaum.
Cov Ntsiab Cai Tswj Xyuas Zoo
Khoom thickness uniformity yog ib tug tseem ceeb zoo qhia. Kev tshuaj xyuas online feem ntau siv tsis yog- tiv tauj cov ntsuas ntsuas rau lub sijhawm tiag tiag - saib xyuas.
Kev tswj cov dej noo ncaj qha cuam tshuam rau tom qab ziab lub zog noj. Nws yog feem ntau tswj los ntawm kev kho lub siab nias thiab nyob twj ywm lub sij hawm.
Cov qauv kev ncaj ncees yuav tsum tau ua kom ntseeg tau thaum cov khoom tsim tawm. Rau cov txheej txheem nyuaj, nce compressed cua siab rau ib ncig ntawm 0.25 MPa tej zaum yuav tsim nyog. Kev tuav cov pwm saum npoo tiav kuj tseem ceeb heev, yuav tsum tau ntxuav cov kua qaub kom tshem tawm cov nplais fiber ntau.
Kev Ua Haujlwm Zoo Tshaj Plaws
Lub sijhawm tsim khoom yog qhov tseem ceeb cuam tshuam rau lub peev xwm ntau lawm. Kev ua kom zoo ntawm lub tshuab nqus tsev layout tuaj yeem txo lub sijhawm nqus nqus los ntawm kwv yees li 15%. Kev siv dual - chaw nres tsheb hloov chaw ua haujlwm tuaj yeem txhim kho kev siv cov cuab yeej zoo.
Ib qho khoom lag luam tsis siv neeg cov nyiaj them poob haujlwm pab tswj kom muaj kev sib haum xeeb thaum lub sijhawm tsim khoom. Tam sim no, cov cuab yeej siv siab dua siv PLC-raws li tag nrho- tswj kev tswj hwm. Cov neeg ua haujlwm tsuas yog yuav tsum tau teeb tsa cov txheej txheem tsis ua kom tiav tag nrho cov voj voog ntau lawm.
