Dragging number case yog hais txog cov txheej txheem ntawm laminating, qhov twg cov kua nplaum rub tawm cov txheej txheem ntawm lub tshuab luam ntawv ntawm lub tshuab luam ntawv substrate, ua rau tus number case ua raws li cov roj hmab sab saud lossis cov menyuam mesh. Qhov tshwm sim yog cov ntawv tsis tiav lossis xim, ua rau cov khoom raug muab pov tseg. Ntxiv mus, tus number case txuas rau sab saum toj cov kua nplaum yog hloov mus rau cov qauv tom ntej, ua rau khib nyiab. Cov xim tsis muaj xim muaj cov xim pleev xim thiab txo qis hauv qhov pom tseeb, uas cuam tshuam rau cov khoom zoo.
1.Nws muaj feem xyuam rau tus nqi ntawm cov kua nplaum siv thiab kev ua haujlwm siab
Qhov tshwm sim ntawm ib feem kub yaj nplaum nplaum nplaum nplaum yog siab dua li ntawm ob qho khoom nplaum,uas yog inseparable los ntawm lub ntsiab nplaum hom thiab diluent.
Vim yog siv cov kua nplaum me me, tus number case dragged down yog nyob rau hauv daim ntawv ntawm cov xov zoo, zoo li cov cim tshwm sim los ntawm meteors. Cov dots zoo no pom tau zoo tshaj plaws nyob rau hauv qhov chaw dawb paug ntawm cov yas zaj duab xis, thiab nyob rau hauv cov qauv, yuav tsum tau ceev faj saib xyuas lawv. Tus nqi gluing ntawm scraper hom qhuav laminating tshuab yog txiav txim siab los ntawm cov kab thiab qhov tob ntawm cov menyuam anilox. Lub siab dhau ntawm lub scraper thaum lub sijhawm ua haujlwm tiag tiag kuj tseem yuav txo cov kua nplaum siv. Yog tias cov kua nplaum siv me me, qhov tshwm sim ntawm kev rub tus number case yog qhov hnyav, thaum yog tias cov kua nplaum siv ntau heev, qhov tshwm sim ntawm dragging number case yog txo.
Qhov concentration ntawm homework yog ze ze rau qhov tshwm sim ntawm number case dragging.Yog tias qhov concentration ntawm ib qho nplaum nplaum tsawg dua 35%, cov ntsiab lus ntawm cov nplaum tseem ceeb yog tsawg dua 3g /㎡, los yog qhov concentration ntawm ob feem reactive nplaum yog tsawg dua 20%, thiab cov ntsiab lus ntawm cov nplaum tseem ceeb yog tsawg dua 3.2g /㎡, nws yog ib qho yooj yim tshwm sim number case drawing phenomenon, uas yog tseem muaj feem xyuam rau cov txheej txheem kev khiav hauj lwm. Yog hais tias qhov kev khiav hauj lwm concentration yog tsawg thiab number case dragging tshwm sim, nws yog ib qhov tsim nyog yuav tau ua kom cov kev khiav hauj lwm concentration los daws nws, uas txhais tau hais tias nce tus nqi ntawm tus neeg sawv cev tseem ceeb los yog txo tus nqi ntawm diluent siv.Feem ntau, kev ua haujlwm siab ntawm ib qho kev tivthaiv yog tswj ntawm thaj tsam 40%, thiab nws yog qhov zoo tshaj plaws los tswj cov concentration ntawm ob lub ntsiab lus ntawm ib ncig ntawm 25-30%, kom cov number case dragging tshwm sim tuaj yeem daws tau.
2. Muaj feem xyuam rau lub siab ntawm cov kua nplaum nplaum
Nyob rau hauv cov txheej txheem qhuav composite, ib tug gluing siab roller feem ntau yog siv, uas yog siv rauua kom cov gluing txheej ntau yam sib xws thiab txo cov tiam ntawm npuas. Thaum tus number case dragging tshwm sim, ntxiv rau kev txiav txim siab ntawm cov kua nplaum siv thiab cov concentration ntawm kev ua haujlwm, nws yog lub siab ntawm cov menyuam roj hmab.
Feem ntau, thaum lub siab tshaj 4MPa, muaj peev xwm ntawm tus number case dragging. Txoj kev daws teeb meem yog txo qis, thiab tib lub sijhawm, tus neeg ua haujlwm txawj yuav tsum siv daim ntaub los lo rau ib lub diluent los so cov xim ntawm cov menyuam anilox. Yog tias nws hnyav dhau lawm, lub anilox roller yuav tsum tau nres rau kev ntxuav.
3. Muaj feem xyuam rau qhov zoo ntawm cov kua nplaum rau cov menyuam
Cov menyuam roj hmab yogtsis du los yog muag heev, thiab tej zaum yuav luag tus cwj mem, uas yog yooj yim tshaj plaws xav txog ntawm ib qho khoom kub yaj nplaum nplaum.
Vim yog qhov tsis sib xws thiab roughness ntawm cov resin, tus number case rub tawm yog qhov tsis sib xws thiab tsis sib xws, tawm hauv cov xim xim hauv qhov chaw dawb paug, ua rau txo qis pob tshab, number case poob hauv cov xim, thiab cov ntawv tsis tiav. Txhawm rau hloov qhov tshwm sim no, nws yog ib qho tsim nyog los hloov qhov du thiab muag heev gluing roller.
4. Muaj feem xyuam rau lub tshuab ceev thiab ziab kub
Qhov ceev ntawm lub tshuab qhia tau hais tias qhov sib cuam tshuam ntawm cov kua nplaum txheej thiab cov nplaum ntawm cov zaj duab xis txheej tau hloov pauv hauv lub sijhawm ntub dej.
Feem ntau, vim lub tshuab qeeb qeeb, muaj qhov tshwm sim ntawm tus number case dragging, uas yog daws los ntawm kev ua kom ceev thiab txo lub sij hawm nyob nruab nrab ntawm tus number case txheej thiab cov nplaum interface. Hauv txoj kev xav, yog tias lub tshuab ceev tau nce, qhov ziab kom qhuav yuav tsum tau nce ntxiv. Nyob rau tib lub sijhawm, yog tias lub tshuab ceev tau nce ntxiv thaum lub sijhawm ua haujlwm tiag tiag, nws yuav tsum tau saib xyuas seb puas muaj lwm yam tsis raug, xws li kev hloov khoom siv, thiab kev hloov kho yuav tsum tau ua.
5. Muaj feem xyuam rau adhesion ntawm luam ntawv substrate los yog number case
Yog tias ntau hom number case yog siv rau gravure printing, qhov tshwm sim ntawm faults yog feem ntau yooj yim xav txog thaum lamination.
Ink tuaj yeem muab faib ua tus number case printing thiab puab number case. Vim muaj ntau hom number case, lawv adhesion yuav txawv los yog tsis sib xws, thiab tsis muaj zog adhesion tuaj yeem ua rau qaug zog adhesion. Thaum siv cov lamination qhuav, nws yooj yim los ua tus number case dragging. Thaum qhov nro ntawm lub tshuab luam ntawv substrate tsis zoo, nws yog qhov yooj yim rau tus number case dragging.
Cov ntawv rub tawm cov kua nplaum tshwm tag nrho, thiab tus number case adheres rau cov kua nplaum, ua rau turbidity thiab av. Yog tias nws tau luam tawm lawm, txhawm rau kom tsis txhob pov tseg, lub tshuab ceev tuaj yeem nce ntxiv, cov kua nplaum tuaj yeem nce ntxiv, thiab cov kua nplaum tuaj yeem nce ntxiv rau tib lub sijhawm. Txo lub siab ntawm cov roj hmab cov menyuam thaum txo qhov tsis sib haum xeeb.
6. Muaj feem xyuam rau cov khoom siv tshuab
Thaum lub sij hawm ua hauj lwm, yog hais tias mechanical tsis ua hauj lwm tshwm sim, ua rauuneven gluing los yog txheej tsis zoo, nws kuj tuaj yeem ua rau number case dragging.
Lub synchronization ntawm lub Upper roj hmab cov menyuam thiab cov anilox cov menyuam yog ua tiav los ntawm ob lub zog sib txuam. Yog tias muaj qhov tshwm sim ntawm tus number case dragging, yuav tsum tau ua tib zoo soj ntsuam. Nws yuav pom tias tus number case dragging tshwm sim los ntawm kev co ntawm cov roj hmab sab saud thiab cov txheej tsis zoo. Yog vim li cas rau qhov co yog vim hnyav hnyav thiab asynchronous iav hniav.
Yog tias koj muaj cov kev cai ntim khoom, koj tuaj yeem tiv tauj peb. Raws li cov chaw tsim khoom lag luam hloov pauv tau ntau dua 20 xyoo, peb yuav muab koj cov kev daws teeb meem zoo raws li koj cov khoom xav tau thiab peev nyiaj.
