Astaamaha shaqada ee qalabka epoxy resin
Astaamaha shaqada ee qalabka epoxy resin
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 heerkulbeegga sare ee adag.
2. Daawaynta habboon: Dooro noocyo kala duwan oo dawooyin ah oo kala duwan, iyo nidaamka resin epoxy waxaa lagu daweyn karaa heerkul ah 0~180℃.
3. Xabag adag: Xabagta dabaylaha ee hydroxyl iyo ether bonds ee silsiladda molecular ee resin epoxy ayaa ka dhigaya mid aad ugu dheggan walxo kala duwan. Hoosudhaca resin epoxy waa hooseeyaa marka la daweynayo, iyo walbahaarka gudaha ka dhasha waa mid yar, kaas oo sidoo kale gacan ka geysta hagaajinta xoogga adhesion.
4. Yaraynta hoose: falcelinta resin epoxy iyo wakiilka daawaynta waxa lagu fuliyaa falcelin toos ah oo dheeraad ah ama falcelinta polymerization giraanta-furan ee kooxda epoxy in molecule resin, oo aan biyo ama wax kale oo kacsan by-products la sii daayo. 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. Guryaha makaanikada: Nidaamka xajinta epoxy ee la daweeyay wuxuu leeyahay sifooyin farsamo oo aad u fiican.
6. Guryaha korantada: Nidaamka resin epoxy la daaweeyay waa walax aad u fiican oo dahaaran oo leh sifooyin dielectric sare ah, caabbinta dheecaanka dusha sare, iyo caabbinta arc.
7. Degganaanshaha kiimikada: Guud ahaan, nidaamka resin epoxy la daaweeyay waxa uu leeyahay iska caabin alkali aad u fiican, caabbinta acid iyo caabin dareere. Sida sifooyinka kale ee nidaamka epoxy-ga ee la daweeyay, xasiloonida kiimikaad waxay sidoo kale ku xiran tahay xabagta la doortay iyo wakiilka daaweynta. Xulashada habboon ee xabagta epoxy-ga iyo wakiilka daawayntu waxay ka dhigi kartaa inay yeelato xasilooni kiimikaad gaar ah.
