Txheej txheej thev naus laus zis yog ib qho tseem ceeb tshaj plaws hauv kev txhim kho kev ua tau zoo thiab ua haujlwm ntawm cov xov paj kub-melt thiab cov advesion siab. Ua tiav cov txheej txheej niaj hnub thiab cov nplaum nplaum muaj zog muaj txiaj ntsig los tswj cov txheej txheem txheej txheej, cov khoom xaiv, thiab txheej txheem tsis. Hauv qab no yog cov txheej txheem tseem ceeb thiab cov tswv yim los ua kom tiav cov txheej txheej sib xyaw thiab cov khoom zoo nkauj siab rau ntawm kub-paj:
1. Kev xaiv ntawm txheej khoom
Kub-melt adhesives: Kev xaiv ntawm kub-melt nplaum (HMA) ua si lub luag haujlwm tseem ceeb hauv kev ua tiav siab adhesion. Xaiv cov khoom siv txheej ua cov khoom siv nrog cov khoom sib cog lus zoo rau lub substrate (xws li polyester, nylon, lossis lwm yam ntaub ntawv). Cov kev xaiv nrov muaj xws liEva (Ethylene-Vinyl acetate), niam zeb meej, thiabpolyurethane, uas paub txog lawv cov nplaum muaj zog thiab sib xyaw nrog ntau yam fibers.
Nplaum nplaum viscosity: Viscosity ntawm kub-yaj nplaum yuav tsum tau ua kom zoo rau cov xov paj. Dhau dhau ntawm lub viscosity yuav ua rau cov txheej tsis sib xws, thaum lub sijhawm qis dhau ntawm cov viscosity yuav ua rau cov neeg tsis muaj txiaj ntsig. Lub viscosity yuav tsum tau xaiv raws li cov xov paj thiab cov khoom xav tau txheej txheej tuab.
2. Nto Kho Cov Xov Paj
Cov Kev Ua Kom Zoo: Rau cov khoom nplaum zoo dua, cov xov paj lub npoo av yuav xav tau kho ua ntej thov txheej txheem. Cov Kev Kho Cov Nto Muaj xws lintshav kho mob, nplaim taws kho, lossisKev Siv Tshuaj Etching, uas pab txhawb cov hluav taws xob saum npoo thiab txhim kho txoj kev sib raug zoo ntawm cov paj thiab cov khoom txheej txheej.
Yug: Thov ib txheej primer ua ntej txheej tuaj yeem txhim kho adhesion, tshwj xeeb yog cov xov paj yog qhov nyuaj rau kev sib khi nrog cov nplaum kub-melt. Tus thawj pib pab tsim kom muaj kev sib txuam zoo dua ntawm cov xov paj thiab txheej, ua kom muaj zog adhesion.
3. Txheej Txheej Txheej
Hnia txheej: Cov qauv no cuam tshuam nrog lub teeb txheej txheej, uas cov xov paj hla los ntawm cov chav dej lossis tus neeg thov, thiab tsuas yog txheej nyias ntawm cov nplaum yog siv. Qhov "hnia" ntawm cov nplaum ua kom muaj txiaj ntsig txawm tias txheej hla cov yarn yam tsis muaj kev tsim paub ntau dhau. Hom qauv no yog qhov zoo tagnrho rau kev ua tiav cov txheej txheem qub hauv cov khaubncaws nyias nyias.
DIP Txheej: Hauv cov txheej txheem no, cov xov paj yog dipped rau hauv cov nplaum kub-yaj, uas yog tom qab ntawd txias thiab ua tau zoo li cov xov paj tawm ntawm cov khaub ncaws txheej. Txhawm rau kom ntseeg tau txheej txheej, cov xov paj yuav tsum tau rub los ntawm da dej ntawm qhov nrawm nrawm, thiab cov nplaum yuav tsum tau ua kom zoo nkauj kom ua kom muaj cov txheej.
Extrusion Txheej: Cov qauv no cuam tshuam nrog kev cuam tshuam molten kub-yaj adesive ncaj qha rau cov xov paj thaum nws kis los ntawm ib txheej tuag. Cov txheej txheem ua kom ntseeg tau tias cov txheej ua kom zoo nkauj nyob thoob plaws cov xov paj. Kev tswj qhov hloov kho qhov kub thiab txias thiab lub siab yog qhov tseem ceeb kom ua tiav cov txheej sib xws.
COV MENYUAM TXHEEJ: Hauv cov qauv no, cov xov paj yog dhau los ntawm cov menyuam coated nrog lub kub-yaj adhesive. Lub siab tau muab pov tseg los ntawm cov chais pab kom nthuav tawm cov nplaum uas muaj cov xov paj. Kho cov menyuam sib txawv thiab cov nplaum viscosity yog qhov tseem ceeb los xyuas kom meej cov ntawv thov uas muaj kev sib raug zoo.
4. Kub thiab ceev tswj
Txheej kub: Txheej txheem txheej txheej txheej yuav tsum tau ua nyob rau ntawm ib qho kev kub siab kom ntseeg tau qhov kub-melt nplaum tseem nyob hauv lub xeev kua thiab yoov tshaj cov xov paj. Kev kub dhau ntawm qhov kub tuaj yeem ua rau ntev melting lossis dripping, thaum tsis tshua muaj qhov kub thiab txias yuav ua rau muaj cov admesion tsawg. Cov nplaum yuav tsum tau rhaub rau txoj cai viscosity thiab sib xws rau cov xov paj.
Xov paj ceev: Qhov ceev uas cov xov paj tsiv los ntawm cov txheej txheem coating cuam tshuam rau cov tuab thiab sib zog ntawm txheej. Ib qho tsis tu ncua thiab tswj nrawm nrawm dua cov nplaum tau thov covyees, tiv thaiv kev ua txhaum lossis hla thaj chaw.
5. Txias thiab Kho Cov Txheej Txheem
Cua txias tus nqi: Tom qab cov nplaum kub-melt yog siv, nws yuav tsum yog qhov txias ntawm tus nqi kom ruaj khov kom zoo. Yog tias tus txheej txheem txias yog nrawm heev, nws yuav ua rau txheej tsis sib xws lossis cov kab nrib pleb hauv txheej. Yog tias qhov txias txias yog qeeb heev, cov nplaum yuav tsis sib txuas ua haujlwm zoo. Cua txias nrog cov pa hluav taws xob tswj hwm lossis dej system pab ua tiav cov khaub ncaws hnav thiab cov txheej txheem ruaj khov.
Kho (yog tias tsim nyog): Qee cov txheej txheej yuav xav tau kev kho cov txheej txheem los txhim kho adhesion thiab bond zog. Thaum feem ntau kub-melt adhesives solorify thaum lawv txias, qee cov txheej txheem ntxiv siv siv UV teeb
6. Kev tswj kom zoo thiab tshuaj xyuas
Thickness ntsuas: Siv precision ntsuas cov cuab yeej (xws liMicrometerslossisgauges laser) Los saib xyuas thiab xyuas kom meej tias cov txheej uas tau thov cov khoom sib txawv thoob plaws ntawm cov xov paj. Qhov no yuav pab kom ua tau zoo ib yam hauv cov khoom kawg.
Kev tshuaj nplaum nplaum: Ua cov nplaum ntsuas (xws liTev xeemlossisShear kuaj) Los ntsuas lub zog ntawm txoj kev sib khi ntawm cov paj thiab txheej. Cov kev ntsuam xyuas no pab txheeb xyuas qhov txheej txheej zoo rau cov xov paj thiab tuaj yeem tiv taus cov kev ntxhov siab nws yuav ntsib thaum lub sijhawm ntawv thov.
7. Kev Kho Mob Tom Qab
Thaum Tshav Kub Kub Teeb: Tom qab txheej, ntsuas cua sov teeb tsa cov xov paj tuaj yeem pab txhim kho txheej txheej ruaj khov thiab cov nplaum. Cov txheej txheem no cuam tshuam nrog cov xov paj rau ib txoj kev kho cua sov, uas tso cai rau cov nplaum kom tiav thiab khi rau cov xov paj.
Kev kho cov kev ua tiav: Ua raws li cov khoom xav tau ntawm cov khoom kawg, kev kho ua tiav ntxiv, xws lisoftening, Kev kho mob antistatic, lossiskev ua dej nag, tej zaum yuav tau thov rau cov xov paj coated. Cov kev kho mob no tuaj yeem txhim kho cov kev ua tau zoo tag nrho thiab kev ua haujlwm ntawm cov xov paj ntawm cov xov paj hauv cov ntawv thov tshwj xeeb.
