Los ntawm kev xav ntawm chemistry, ziab thiab kho yog ob lo lus uas muaj lub ntsiab lus sib txawv uas peb niaj hnub pom cov neeg tsis meej pem thaum xa mus rau kev siv.PU laminated nplaum nplaum.
Kev ziab kom qhuav txhais tau tias qhov poob ntawm cov kua dej ntawm cov nplaum. Nws yog cov evaporation ntawm cov cab kuj zoo li cov kuab tshuaj los yog dej ntxiv los ua cov kua nplaum nplaum, uas ua rau cov yeeb yaj kiab zoo. Cov nplaum yog cov tshuaj tsis hloov pauv ntawm cov txheej txheem, thiab cov khoom qhuav tseem soluble hauv cov kuab tshuaj qub. Qhov no terminology feem ntau yog hais txogkuab tshuaj raws li nplaumthiab dej-raws li adhesives.
Curing yog hais txog cov tshuaj tiv thaiv uas tshwm sim thaum lub sij hawm thov los yog siv cov nplaum. Nws yog qhov tshwm sim ntawm ob lub ntsiab lus reacting lossis cross-linking, uas ua rau lub cev hloov pauv ntawm cov kua mus rau cov khoom. Cov txheej txheem no yog irreversible. Cov lus qhia no hais txog cov dej-kho polyurethane nplaum,ob-cov khoom hnyav-dawb nplaum nplaum. Nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm kev ziab thiab kho rau kev xaiv cov khoom. Adhesives uas kho tau kub dua thiab dej-tiv taus piv rau cov khoom uas qhuav. Yog li kom ntseeg tau tias koj muaj cov nplaum zoo uas yuav tsum tau ua rau daim ntawv thov tshwj xeeb yog qhov tseem ceeb heev.
