Hordhac sifada guddiga fiber galaas galaxy xabagta xabagta epoxy

1. 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 ℃.

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

3. Adhesion xoog leh. Kooxaha hydroxyl -ka dabaysha ku jira iyo xidhmooyinka ether ee silsiladda molecular ee resins epoxy waxay ka dhigaan mid aad ugu dheggan walxaha kala duwan. Hoos -u -dhaca resin epoxy -ku wuu hooseeyaa marka la daaweynayo, iyo walbahaarka gudaha ka dhashay waa yar yahay, kaas oo waliba gacan ka geysanaya hagaajinta xoogga dhegdhegga.

4. Yaraynta hoose. Dareen-celinta u dhaxaysa xabagta epoxy-ga iyo wakiilka daawaynta ee la isticmaalo waxa lagu fuliyaa fal-celin toos ah oo dheeraad ah ama falcelinta polymerization-ka-furay ee kooxaha epoxy-ga ee molecule-ka xabagta, oo aan biyo ama alaab kale oo kacsani soo baxayn. Marka la barbar dhigo resins polyester-ka aan dheregsanayn iyo xabagta phenolic, waxay muujinayaan hoos u dhac aad u hooseeya inta lagu jiro daaweynta.

5. 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.
