Hauv kev lag luam mos- ntim khoom, kev hloov kho thev naus laus zis tsom rau "ntsuab, ua haujlwm tau zoo thiab nyab xeeb" tab tom ua ntsiag to. Cov kuab tshuaj-dawb lamination, raws li cov thev naus laus zis tshiab, yog maj mam hloov cov lamination qhuav raws li cov lus qhia tseem ceeb ntawm kev txhim kho kev lag luam. Yog li dab tsi yog qhov txawv ntawm ob txheej txheem?
Lub hauv paus ntawm ib txwm qhuav lamination yog siv cov kuab tshuaj organic xws li ethyl acetate ua cov khoom siv ntawm cov nplaum. Cov kuab tshuaj yog evaporated los ntawm txheej, ziab thiab laminating kom ua tiav zaj duab xis sib txuas. Txawm li cas los xij, nws qhov tsis zoo yog qhov pom tseeb: qhov loj ntawm cov kuab tshuaj evaporates thaum lub sijhawm tsim khoom, ua rau muaj kev phom sij rau hluav taws, tso cov organic sib txuas thiab ua paug rau ib puag ncig; tib lub sijhawm, cov txheej txheem ziab yog lub zog- hnyav thiab tuaj yeem ua rau muaj kev pheej hmoo ntawm cov kuab tshuaj residue.
cov kuab tshuaj-dawb lamination tshuab, los ntawm qhov sib txawv, qhia txog qhov zoo ntawm kev hloov pauv. Nws siv 100% solids adhesives thiab yuav tsum tsis muaj cov kuab tshuaj. Nyob rau hauv chav tsev kub, ob qho - cov nplaum nplaum yog sib xyaw siv cov khoom sib xyaw ua ke, siv ncaj qha rau hauv substrate thiab laminated tam sim ntawd. Nws ua haujlwm los ntawm kev tshem tawm cov kuab tshuaj siv ntawm qhov chaw yam tsis tas yuav tsum muaj lub tshuab ziab khaub ncaws loj.
Los ntawm kev sib piv, qhov zoo tshaj ntawm cov kuab tshuaj-cov thev naus laus zis yog tus kheej- pom tseeb:
- Kev tiv thaiv ib puag ncig: ua tiav xoom emissions ntawm volatile organic tebchaw nyob rau hauv tag nrho ua raws li lub teb chaws ib puag ncig txoj cai.
- Kev tsim khoom nyab xeeb: tshem tawm cov hluav taws kub thiab tawg phom sij los ntawm cov kuab tshuaj.
- Kev txuag hluav taws xob zoo: tsis tas yuav qhuav, txo kev siv hluav taws xob zoo, ua kom cov kab ntau lawm ceev.
- Kev nyab xeeb ntawm cov khoom: tsis muaj cov kuab tshuaj residue, tshwj xeeb tshaj yog rau ntim nrog kev tu cev zoo, xws li zaub mov, tshuaj, thiab lwm yam.
Hauv kev xaus, hnyav- thev naus laus zis lamination dawb, nrog rau nws cov txiaj ntsig zoo ntawm kev tiv thaiv ib puag ncig, kev nyab xeeb, kev ua haujlwm thiab tus nqi qis, yog qhov kev xaiv tsis raug rau kev tsim kho kom ruaj khov ntawm kev lag luam ntim khoom muag. Solvent- thev naus laus zis pub dawb tsis yog qhov tseem ceeb los txhim kho kev sib tw ntawm kev lag luam, tab sis kuj yog peb lub luag haujlwm los tiv thaiv ib puag ncig.
