Ntau hom ntawv. Ntau hom resins, cov neeg ua kom zoo, thiab hloov kho tshuab tau yoog raws li cov qauv ntawm daim ntawv rau ntau yam kev siv, xws li kev tawm tsam tsis tshua muaj siab mus rau qhov siab ntawm cov teeb meem melting.
E pab kom kho. Epoxy resin system tuaj yeem kho nyob rau hauv qhov kub ntawm 0-180 ° C los ntawm kev siv ntau yam tshuaj tua kab mob.
Muaj zog adhesion. Lub xub ntiag ntawm polar hydroxyl thiab ether linkages inherent nyob rau hauv cov epoxy cob mis molecular saw muab adhesion siab rau ntau cov ntaub ntawv. Thaum twg cov epoxy rein kho, cov shrinkage tsawg tsawg, thiab cov kev ntxhov siab sab hauv yog me me, uas tseem muaj txhawb rau kev txhim kho nyob rau hauv adhesion zog.
Tsawg shrinkage. Cov tshuaj tiv thaiv ntawm cov tshuaj reag ntawm epoxy thiab cov neeg siv tshuaj tua kab yog siv los ntawm qhov tshuaj tiv thaiv kab mob ncaj qha los yog lub nplhaib qhib tua polymerization ntawm ib pawg epoxy nyob hauv ib qho tshuaj molecule, tsis tso tawm dej los yog lwm yam khoom siv tsis taus. Lawv pom tsawg kawg qis (tsawg dua 2%) thaum lub sij hawm kho dua rau cov ntaub ntawv tsis muaj cov polyester resins thiab phenolic resins.
