Daim ntawv thov yam ntxwv ntawm epoxy iav fiber ntau raj
Epoxy fiberglass yeeb nkab yog ib qho khoom siv hauv cov khoom siv hluav taws xob hauv lub hnub nyoog tam sim no. Vim nws cov yam ntxwv ntawm cov khoom siv, nws tuaj yeem siv los ua ib feem ntawm cov khoom siv insulating. Thiab txawm nyob rau hauv ib puag ncig ntub, nws kuj tseem siv tau nrog cov roj transformer. Tom ntej no, peb yuav qhia txog kev siv cov yam ntxwv ntawm epoxy iav fiber ntau raj hauv kev nthuav dav.
Siv cov yam ntxwv ntawm epoxy iav fiber ntau raj
1. Ntau hom ntawv. Ntau yam resins, curing agents, thiab modifier systems tsuas yog siv tau raws li qhov yuav tsum tau muaj ntawm ntau hom kev siv, thiab lawv cov nplais tuaj yeem nyob ntawm qhov tsis tshua muaj viscosity mus rau siab melting point solids.
2. Yooj yim kho. Xaiv ntau yam khoom sib txawv, cov txheej txheem epoxy resin tuaj yeem kho tau 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 shortening 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 luv luv. 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 hauv cov molecule resin, thiab tsis muaj dej los yog lwm yam khoom lag luam tawm. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv qhia luv luv luv (tsawg dua 2%) hauv cov txheej txheem kho.
5. Cov khoom siv dag zog. Cov txheej txheem kho epoxy resin muaj cov cuab yeej zoo heev.
