Dab tsi yog cov yam ntxwv ntawm epoxy yeeb nkab thov?
Dab tsi yog cov yam ntxwv ntawm epoxy yeeb nkab thov?
Thawj yog muaj zog adhesion. Epoxy yeeb nkab tau zoo adhesion rau ntau yam ntaub ntawv. Qhov no yog vim hais tias cov epoxy resin siv nyob rau hauv cov yeeb nkab epoxy muaj qis shortening thiab sab hauv kev nyuaj siab thaum lub sij hawm kho, uas yog tseem conducive rau nws tag nrho cov nplaum lub zog.
Qhov thib ob yog ntau haiv neeg. Ntau yam epoxy resins, curing agents thiab modifier systems muaj peev xwm ua tau raws li qhov yuav tsum tau muaj ntawm ntau txoj kev thov, thiab cov kev npaj muaj peev xwm kuj muaj xws li los ntawm qhov tsis tshua muaj viscosity mus rau siab melting point solids.
Thib peb, zoo mechanical zog. Kho epoxy resin muaj cov cuab yeej zoo heev.
Qhov luv luv ntawm lub voj voog thib plaub kuj tsawg heev. Cov tshuaj tiv thaiv ntawm epoxy resin thiab tus neeg sawv cev kho yog ua los ntawm cov tshuaj tiv thaiv ncaj qha los yog lub nplhaib qhib polymerization ntawm epoxy pawg hauv cov molecule resin. Tsis muaj dej los yog lwm yam khoom siv hluav taws xob tawm. Piv nrog unsaturated polyester resin thiab phenolic resin, nws muaj tsawg shrinkage tus nqi thaum kho.
Qhov thib tsib yog yooj yim. Los ntawm kev xaiv cov tshuaj tua kab sib txawv, epoxy resin system ntawm epoxy yeeb nkab tuaj yeem kho tau ntawm 0 ~ 180 ° C.
