Horudhac ku saabsan sifooyinka functional codsiga ee looxa fiber galaas epoxy
Horudhac arjiga shaqaynaya sifooyinka looxa fiber galaas epoxy
Epoxy fiber board fiber galaas, epoxy phenolic laminated galaas board, xabagta epoxy guud ahaan waxaa loola jeedaa xeryahooda polymer organic ka kooban laba ama in ka badan kooxaha epoxy ee molecule ah, marka laga reebo qaar ka mid ah, ay qaraabo cufan molecular ma aha sare. Qaab dhismeedka molecular ee resin epoxy waxaa lagu gartaa kooxda epoxy-ga firfircoon ee silsiladda molecular. Kooxda epoxy-ga waxay ku yaalliin dhamaadka, dhexda ama qaabdhismeedka meertada ee silsiladda molecular. Sababtoo ah qaab-dhismeedka kelli wuxuu ka kooban yahay kooxaha epoxy-ga firfircoon, waxay mari karaan falcelin isku-dhafan oo leh noocyo kala duwan oo wakiilada daaweynta si ay u sameeyaan polymers aan la milmi karin oo aan la dafiri karin oo leh qaab-dhismeedka shabakad saddex-gees ah.
Astaamaha iyo shaqooyinka codsiga sanduuqa fiber-ka galaas ee Epoxy:
1. Guryaha farsamada. Nidaamka cusbi ee bogsaday wuxuu leeyahay sifooyin farsamo oo aad u fiican.
2. 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.
3. 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 ℃.
4. 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.
5. 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.
