Waa maxay sifooyinka codsiga ee tuubada fiber galaas epoxy?

1. Qaabab kala duwan. Rinjiga kala duwan, wakiilada dawaynta, iyo hababka wax -ka -beddelka ayaa ku dhawaad ​​la qabsan kara shuruudaha dalabyada kala duwan ee foomka, iyo kala -duwanaantu waxay noqon kartaa mid aad u hooseeya ilaa dhibco dhalaalaya oo sare.

2. Daaweyn habboon. Dooro wakiilo kala duwan oo wax -ka -qabad leh oo kala duwan, nidaamka cusbi ee epoxy ayaa ku dhawaad ​​lagu daaweyn karaa xaddiga heerkulka 0 ~ 180 ℃.

3. adhesion xoog leh. Jiritaanka polar hydroxyl iyo ether bond [1] ee ka dhex jira silsiladda molecular ee xabagta epoxy ka dhigaysa inay yeelato ku dheggan walxaha kala duwan. Hoosudhaca resin epoxy waa hooseeyaa marka la daaweynayo, iyo walbahaarka gudaha ee ka dhasha waa mid yar, kaas oo sidoo kale gacan ka geysta hagaajinta awoodda adhesion.

4. Yaraynta hoose. Dareen-celinta u dhaxaysa xabagta epoxy-ga iyo wakiilka daawaynta ee la isticmaalo waxa lagu fuliyaa falcelin toos ah oo dheeraad ah ama falcelinta polymerization giraanta ee kooxaha epoxy-ga ee molecule-ka xabagta, oo aan biyo ama wax-soo-saar kale oo kacsani sii dayn. Marka la barbar dhigo resins polyester-ka aan dheregsanayn iyo xabagta phenolic, waxay muujinayaan hoos u dhac aad u hooseeya (in ka yar 2%) inta lagu jiro daawaynta.

5. Guryaha farsamada. Nidaamka cusbi ee bogsaday wuxuu leeyahay sifooyin farsamo oo aad u fiican.
