Yuav ua li cas yog epoxy fiberglass board?

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. Siv ntau yam tshuaj tua kab mob, cov txheej txheem epoxy resin tuaj yeem yuav luag kho tau hauv qhov kub ntawm 0 ~ 180 ℃.

3. Muaj zog adhesion. Lub hauv paus ntsiab lus ntawm polar hydroxyl pawg thiab ether daim ntawv cog lus nyob rau hauv molecular saw ntawm epoxy resin ua rau nws muaj siab adhesion 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 raug tso tawm. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv pom tsawg heev shrinkage (tsawg dua 2%) thaum kho.

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