Kev ua tau zoo ntawm epoxy cob fixture

1. Ntau hom ntawv. Ntau yam resins, curing agents, thiab modifier systems yuav luag hloov mus rau qhov yuav tsum tau ntawm ntau daim ntawv thov nyob rau hauv daim ntawv, thiab qhov ntau yuav yog los ntawm tsis tshua muaj viscosity mus rau siab melting point solids.

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 nplaum. Cov pab pawg hydroxyl ncov qaumteb qabteb thiab cov ether bonds hauv cov saw hlau molecular ntawm epoxy resins ua rau nws nplaum rau ntau yam tshuaj. Kev nqaim ntawm epoxy resin yog qis thaum kho, thiab kev nyuab siab sab hauv tsim tawm me me, uas tseem pab txhim kho lub zog ua kom khov.

4. Tsawg shrinkage. Cov tshuaj tiv thaiv ntawm cov tshuaj epoxy cob thiab cov tshuaj tua kab siv yog ua los ntawm cov tshuaj tiv thaiv ncaj qha ntxiv lossis lub nplhaib-qhib polymerization cov tshuaj tiv thaiv ntawm epoxy pawg hauv cov tshuaj molecule, thiab tsis muaj dej lossis lwm yam khoom hloov pauv tau tso tawm. Piv nrog cov polyester tsis txaus satin thiab cov phenolic resins, lawv qhia qis qis qis (tsawg dua 2%) thaum kho.

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