Cov khoom ntawm cov khoom siv yooj yim siv hauv cov txheej txheem thev naus laus zis, tshwj xeeb tshaj yog covlaminated adhesives rau polymer films, muaj kev txiav txim siab ntawm kev ua haujlwm ntawm cov laminate tiav. Kev paub txog ntau yam ntawm cov nplaum, nrog rau qhov tshwj xeeb ntawm cov tshuab rau lawv daim ntawv thov, yog lub hauv paus tseem ceeb rau kev txhim kho ntxiv ntawm kev siv tshuab thiab kev kawm txog cov khoom siv tam sim ntawd.
Covnplaum nplaum ntawm cov yeeb yaj kiabtshwm sim feem ntau nyob rau hauv kev cuam tshuam ntawm kev sib cuam tshuam ntawm cov rog nyob rau hauv ciam txheej ntawm cov substrate thiab cov nplaum, thiab nws lub zog nyob ntawm seb qhov xwm thiab tus naj npawb ntawm cov pab pawg neeg, cov qauv ntawm cov ntaub ntawv, thiab interphase nto zog. Vim muaj ntau yam khoom ntawm cov nplaum, ib tus tuaj yeem tsim cov ntaub ntawv uas muaj cov khoom siv tshiab, feem ntau tsis xav txog, tab sis qee zaum kev ua haujlwm tsis zoo thiab cov yam ntxwv.
Hauvzaj duab xis laminating txheej txheem, raws li txoj cai, muaj kev hloov pauv hauv lub xeev ntawm cov nplaum nplaum los ntawm cov kua (uas muab kev sib cuag zoo ntawm cov nplaum thiab cov substrate) kom khov. Qhov no ua rau kom cov viscosity thiab melting point ntawm cov nplaum. Pom tseeb, lub hardener ntawm cov nplaum uas muaj thiab tsis muaj cov kuab tshuaj yuav txawv.
Nyob rau hauv thawj rooj plaub, cov khoom theem nyob rau hauv cov nplaum txheej tshwm vim evaporation ntawm cov kuab tshuaj los yog dispersion nruab nrab thiab ib tug nce nyob rau hauv lub concentration ntawm lub ntsiab tivthaiv - ib tug zaj duab xis-tsim tus neeg sawv cev. Hauv lwm qhov xwm txheej, lubnplaum hardeningyog vim muaj tshuaj lom neeg ua rau muaj ntau yam ntxiv hauv qhov hnyav molecular ntawm lub ntsiab ntawm cov nplaum muaj pes tsawg leeg hauv cov txheej txheem tshuaj, hauv nws cov txheej txheem polymerization thiab crosslinking.
