Performance of epoxy resin fixture
Waxqabadka epoxy resin fixture
1. Noocyo kala duwan. Resins kala duwan, wakiilada daaweynta, iyo hababka wax ka beddelka ayaa ku dhawaad la qabsan kara shuruudaha codsiyada kala duwan ee foomka, iyo kala duwanaansho waxay noqon kartaa mid aad u hooseeya ilaa heerkul sare oo adag.
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. 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. Hoos u dhaca. Dareen-celinta u dhexaysa cusbi epoxy iyo wakiilka dawaynta ee la adeegsado waxaa lagu sameeyaa falcelin toos ah oo toos ah ama falcelinta furitaanka polymerization ee kooxaha epoxy-ga ee molecule-ka cusbada, oo wax biyo ah ama badeecado kale oo aan degganayn lama sii daayo. Marka la barbardhigo maaddada polyester -ka aan la dhergin iyo reexaanta phenolic, waxay muujiyaan yaraanshaha aadka u hooseeya (in ka yar 2%) inta lagu jiro daaweynta.
5. Guryaha farsamada. Nidaamka cusbi ee bogsaday wuxuu leeyahay sifooyin farsamo oo aad u fiican.
