Dab tsi yog daim ntawv thov yam ntxwv ntawm epoxy iav fiber ntau yeeb nkab?

1. Ntau hom ntawv. Ntau yam resins, kho tus neeg sawv cev, thiab hloov kho cov txheej txheem tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm ntau daim ntawv thov ntawm daim ntawv, thiab qhov ntau tuaj yeem yog los ntawm qis viscosity mus rau qhov siab melting point khib nyiab.

2. Yooj yim kho. Xaiv ntau yam sib txawv ntawm cov neeg sawv cev kho kab mob, cov txheej txheem epoxy tuaj yeem yuav luag tau kho hauv qhov kub ntawm 0 ~ 180 ℃.

3. Muaj zog adhesion. Lub hav zoov ntawm polar hydroxyl thiab ether daim ntawv cog lus [1] muaj nyob rau hauv cov saw molecular ntawm epoxy resin ua rau nws muaj adhesion siab rau ntau yam khoom. Lub shrinkage ntawm epoxy resin yog tsawg thaum kho, thiab cov kev ntxhov siab sab hauv tsim yog me me, uas kuj pab txhim kho lub zog adhesion.

4. Tsawg shrinkage. Cov tshuaj tiv thaiv ntawm epoxy resin thiab curing tus neeg sawv cev 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 cov molecule resin, thiab tsis muaj dej los yog lwm yam volatile by-products emissions. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv pom tsawg heev shrinkage (tsawg dua 2%) thaum kho.

5. Cov khoom siv dag zog. Cov txheej txheem kho epoxy resin muaj cov cuab yeej zoo heev.
