Nkag siab txog kev siv cov yam ntxwv ntawm SMC rwb thaiv tsev board

1. Ntau hom ntawv. Ntau yam resins, curing agents, thiab modifier systems yuav luag hloov tau raws li qhov yuav tsum tau ntawm ntau hom kev siv, thiab lawv qhov ntau muaj peev xwm los ntawm tsawg viscosity mus rau siab melting point solids.

2. Yooj yim kho. Siv ntau yam tshuaj tua kab mob, lub rooj tsav xwm insulating yuav luag kho tau hauv qhov kub ntawm 0 ~ 180 ℃.

3. Muaj zog adhesion. Lub hauv paus chiv keeb hydroxyl thiab ether bonds nyob rau hauv molecular saw ntawm epoxy resin ua rau nws nplaum heev rau ntau yam khoom. Lub shortening ntawm epoxy resin yog tsawg thaum kho, thiab cov kev ntxhov siab sab hauv uas tshwm sim yog me me, uas kuj pab txhim kho lub adhesion zog.

4. Tsawg luv luv. 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 khoom los ntawm volatile. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv pom tsawg heev shortening (tsawg dua 2%) nyob rau hauv cov txheej txheem kho.

5.Mechanical zog. Cov rwb thaiv tsev kho kom zoo nkauj muaj cov khoom zoo heev.
