Functional yam ntxwv ntawm epoxy cob fixture

1. Ntau yam ntaub ntawv: ntau yam resins, curing agents, thiab modifier systems yuav luag hloov mus rau qhov yuav tsum tau ntawm ntau yam kev siv ntawm daim ntawv, thiab qhov ntau yuav yog los ntawm tsawg viscosity mus rau siab melting point solids.

2. Kev kho kom yooj yim: Xaiv ntau yam tshuaj tua kab mob sib txawv, thiab epoxy resin system tuaj yeem kho tau ntawm qhov kub ntawm 0 ~ 180 ℃.

3. Muaj zog adhesion: Lub hauv paus ntsiab lus ntawm polar hydroxyl thiab ether bonds nyob rau hauv molecular saw ntawm epoxy resin ua rau nws nplaum heev 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 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 khoom los ntawm cov khoom tsis haum. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv pom tsawg heev shrinkage thaum kho.

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

6. Cov khoom siv hluav taws xob: Cov txheej txheem kho epoxy resin yog cov khoom siv insulating zoo heev nrog cov khoom siv hluav taws xob siab, qhov dej tsis zoo, thiab arc tsis kam.

7. Tshuaj stability: Feem ntau, kho epoxy resin system muaj zoo alkali tsis kam, acid kuj thiab hnyav kuj. Zoo li lwm yam khoom ntawm cov kab mob epoxy kho tau, cov tshuaj lom neeg ruaj khov kuj nyob ntawm qhov xaiv cov resin thiab curing agent. Kev xaiv tsim nyog ntawm epoxy resin thiab tus neeg sawv cev kho tuaj yeem ua rau nws muaj tshuaj lom neeg tshwj xeeb.
