1. Mechanical zog. Lub kho epoxy resin system nthuav tawm cov khoom zoo heev.
2. Yooj yim solidification. Los ntawm kev siv ntau yam tshuaj tua kab mob, epoxy resin system tuaj yeem kho tau nyob rau hauv qhov kub ntawm 0-180 degree .
3. Ntau hom ntawv. Ntau yam resin, curing agent, thiab modifier systems yuav luag ua tau raws li qhov yuav tsum tau muaj ntawm ntau daim ntawv thov rau daim ntawv, xws li los ntawm tsis tshua muaj viscosity mus rau siab melting point solids.
4. Muaj zog adhesion. Lub xub ntiag ntawm polar hydroxyl thiab ether bonds nyob rau hauv molecular saw ntawm epoxy resin muab nws adhesion siab rau ntau yam khoom. Lub shrinkage ntawm epoxy resin thaum kho yog tsawg, ua rau tsis tshua muaj kev ntxhov siab, uas kuj pab txhim kho adhesion zog.
5. Tsawg contractility. Cov tshuaj tiv thaiv ntawm epoxy resin thiab tus neeg sawv cev kho siv yog ua los ntawm cov tshuaj tiv thaiv ncaj qha los yog lub nplhaib qhib polymerization cov tshuaj tiv thaiv ntawm epoxy pawg nyob rau hauv resin molecules, yam tsis tau tso dej los yog lwm yam volatile by-products. Piv nrog unsaturated polyester resin thiab phenolic resin, lawv pom tsawg heev shrinkage (tsawg dua 2%) thaum lub sij hawm kho.
