Solventless laminating tshuab yog ib qho khoom siv tsis tau muaj nyob rau hauv kev lag luam ntim khoom niaj hnub. Nws tau pom dav rau nws cov kev tiv thaiv siab thiab ib puag ncig ib puag ncig. Txawm li cas los xij, thaum lub sijhawm ua haujlwm tiag tiag, cov txheej txheem thev naus laus zis, laminating cov txheej txheem thiab kev tswj hluav taws xob tuaj yeem ua tsis zoo thiab cov khoom lag luam zoo. Hauv daim ntawv no, cov kev ua txhaum cai ntawm cov kuab dawb yog tshuaj xyuas qhov systematically, thiab cov kev daws teeb meem yog tshuaj xyuas raws li cov rooj plaub tiag.
Dab tsi yog qhov nquag ua haujlwm ua txhaum hauv kev ua haujlwm ntawm cov kuab dawb composite tshuab?
Txheej Txheej
Lub txheej txheej txheej yog cov tseem ceeb ntawm cov kuab dawb composite tshuab, thiab nws cov ruaj khov cuam tshuam cov khoom siv zoo. Cov Glitches muaj xws li:
- Tsis txaus ntseeg siab lossis kho kom zoo tsis muaj zog lossis kho tsis tau ua tiav ntawm tus me conveyor cov menyuam: coj mus rau uneven coating tuab tuab lossis txawm tias to taub.
- Tsis zoo ua tiav, tsom iav, deforming lossis tu cov coated cov menyuam yaus: cov khoom siv txawv teb chaws lossis puas tsuaj rau cov menyuam yaus tsis meej xws li riam phom thiab kab txaij. Piv txwv li, ib lub tuam txhab pom cov nplaum nplaum uas muaj cov nplaum ntawm cov khoom sib hloov, ua rau muaj riam ntev riam rau txheej txheej txheej txheej txheej txheej txheej txheej txheej. Hloov cov chais ris cov teeb meem no.
- Qhov sib txawv ntawm cov menyuam yaus lub metering thiab hloov cov tub thiab hloov cov tub luam yog tsis muaj kev sib tw: qhov loj me me lossis ib qho kev sib txawv me me tuaj yeem ua rau ib qho kev sib txawv lossis cov khoom sib hloov. Ua ntu zus calibrate qhov sib txawv ntawm cov chais.
Lub cev winding
Qhov zoo ntawm winding ncaj qha cuam tshuam cov tsos thiab tom ntej kev ua tiav cov khoom tiav. Cov teeb meem tshwm sim muaj xws li:
- Qhwv txoj kev tswj hwm tsis txaus: dhau ib tug taper tuaj yeem ua rau compression deformation ntawm sab nraud cov khoom siv qub, lossis txawm tias `" bungge ''.
- Siab roller rungout lossis daim ntawv tseem ceeb deformation: lub siab cov menyuam yaus tsis muaj zog lossis cov ntaub ntawv ntau dhau yuav ua rau wrinkling thaum winding. Ntawm ib txoj kab ntau lawm, lub ellipse ua rau muaj kev sib tw tsis zoo ntawm PE membrane winding. Hloov cov ntawv tsim nyog tus tub ntxhais kawm kom rov qab ua yeeb yaj kiab rau ib txwm muaj.
- Cov yeeb yaj kiab txom nyem: Cov lus qhia qhia tsis zoo lossis cov lus qhia tsis zoo yuav ua rau yob txav thiab cov khaub lig tsis sib nrug. Tshawb xyuas cov menyuam huv thiab kho cov nro tsis sib haum xeeb.
Laminar Cov Menyuam Khoom Malfunction
Tswj qhov kub thiab lub siab ntawm cov menyuam yaj kev ua tau yog qhov tseem ceeb rau qhov zoo ntawm zaj duab xis:
- Laminated steel roller kub tsis sib xws los yog kev puas tsuaj saum npoo: tsawg dhau kub yuav ua rau tsis tiav ntawm cov nplaum, ua rau cov pob dawb, npuas thiab lwm yam tsis xws luag. Ib lub tuam txhab, piv txwv li, muaj xim dawb paug rau sab nraum qab ntawm cov menyuam laminated laminated vim yog qhov kub ntawm tsuas yog 35 degree. Tom qab tig ntsuas kub txog li 50 degrees Celsius, qhov teeb meem ploj.
- Ua tsis tiav cov ntaub pua plag uas muaj peev xwm tiv thaiv cov menyuam yaus: Flattening Cov Menyuam Tsis Muaj Peev Xwm Ua rau cov txheej txheem tsis sib xws ntawm cov txheej txheem tsis sib xws, ua rau cov kab tsis zoo, ua rau txheej txheem lamination.
Solventless laminating tshuab hauv cov txheej txheem ntawm cov teeb meem sib xws?
Kev Kho Mob thiab Adhesive Ua Tsis Ua Haujlwm
Cov txheej txheem kev kho ncaj qha cuam tshuam rau lub zog tev ntawm cov txheej. Cov teeb meem tshwm sim muaj xws li:
Kev sib xyaw ua ke tsis yog ib qho kev sib xyaw lossis cov piv ntawm ob - Cheebtsam cov nplaum tsis muaj tseeb: qhov chaw qis qis dua ntom ntom ntom thiab txo lub zog. Vim tias qhov txo qis ntawm NCO muaj pes tsawg leeg thiab siv sijhawm tsis txaus, lub zog tev ntawm cov khaubncaws sab nraud tom qab kev kho tus qauv. Kho cov kev sib txuas lus los txuas lub sijhawm kho kom txuas ntxiv.
Cov tshuaj tiv thaiv tsis txaus / lub sijhawm: tsawg kub lossis lub sijhawm kho luv luv tuaj yeem tiv thaiv cov txheej txheem nplaum nplaum {}}}} Cov txheej txheem tsim nyog yuav tsum tau txiav txim siab raws li hom
Cov teeb meem tshwm sim
Cov teeb meem tshwm sim ntawm laminated zaj duab xis yuav txo tus nqi ntawm cov khoom. Hom Hom muaj xws li:
- White spots/bubbles: Bubbles can be caused by inadequate application of adhesive, low substrate surface tension or high workshop humidity (e.g. >70% av noo). Rau NY / PE cov txheej txheem kev txiav txim, ntom npuas yog tsim tom qab lamination vim 85% cov av noo hauv 85 Rhiav thiab cov khoom nplaum qis. Qhov no suav nrog cov av noo thiab nce cov nplaum ntawm cov nplaum.
- Tsis txaus ntseeg kev sib raug zoo lossis cov chaw so substrate tuaj yeem ua rau swb ntawm txheej, tsim qhov - zoo li kab noj hniav. Qhov no yuav tsum tau ua kom zoo ntawm kev tswj hwm nruj.
Cov Khoom Siv Hluav Taws Xob
Cov ntaub ntawv tsis zoo sib xyaw tuaj yeem ua rau Laminar tsis ua haujlwm:
- Ink - cov tshuaj nplaum nplaum. Ua ntej - Txoj kev ntsuas yog qhov tseem ceeb heev.
- Kev hloov pauv ntau dhau: nrawm nrawm kho cov nrawm nrawm lossis cov nplaum tsis zoo sib xyaw tuaj yeem ua rau txhuas txheej ua rau poob. Hauv ib qho kev sim rhaub dej npau npau, ob qho qauv nplaum sib tsoo tsoo ntawm cov txheej txheem txhuas kub, thaum lub siab pab kho qhov kub, qhia tias qhov kev xav tau ntawm cov txheej txheem kev tswj hwm.
Dab tsi yog cov kev ua yuam kev hauv hluav taws xob tswj cov txheej txheem ntawm cov kuab dawb solventless tshuab?
Hybrid system tsis ua hauj lwm
Stirringing qhov tseeb ncaj qha cuam tshuam kev lamination zoo. Cov teeb meem tshwm sim muaj xws li:
Cov khoom siv hluav taws xob zoo li qub los yog tsis siv neeg ua haujlwm: Tsis muaj kev sib xyaw tsis ncaj yuav ua rau txo qis hauv kev ua tiav zoo. Ib qho kev ua tsis tiav hauv ib lub tuam txhab cov mixers tau ua tiav hauv 30% underproduction ntau lawm ntawm huag cov khoom sib xyaw ua ke tom qab muaj kev npau taws. Sensors yuav tsum tau ua kom tsis tu ncua thiab cov raj sib xyaw hloov.
Kev Tswj Kub Kev Kub Tsis Muaj Kub
Qhov kev hloov pauv kub hloov tuaj yeem ua tau zoo ntawm cov txheej txheem kev kho:
- Kev ua tsis tiav hauv cov menyuam laminating cua sov module lossis kub sensor yuam kev tuaj yeem ua rau muaj qhov kub thiab txias hauv qab. Ntawm ib kab ntau lawm, cov hlau cov roj hmab ntsuas kub ua yuam kev ntawm 10 degree, ua rau muaj qhov kub ntawm 48℃(teeb tsa ntawm 55 degree). Tom qab hloov kho, cov khoom tawm khoom nce ntxiv. Qhov nro tswj tsis ua haujlwm
Tension System tseem ceeb rau cov cua tshuab winding. Cov teeb meem tshwm sim muaj xws li:
- Kev ntsuas hluav taws xob ntau zog sensor teeb meem kev cuam tshuam lossis pid parameter misalignment: parameter yuam kev tuaj yeem ua rau muaj kev ua yeeb yam lossis so ntawm zaj duab xis. Cov chaw tsis raug PID tsis raug cai tuaj yeem ua rau zaj duab xis kom ncab thiab ntev ntev pob thaum cua. Qhov no yuav tsum tau rov txiav txim siab thiab tshem tawm ntawm cov khoom siv pov tseg.
