Tilmaamaha codsiga ee tuubada mica
Tilmaamaha codsiga ee tuubada mica
1. Foomamka Kala Duwan: Resins kala duwan, wakiilada daawaynta, iyo hababka wax ka beddelka ayaa si fudud loogu isticmaali karaa shuruudaha noocyo kala duwan, miisaankooduna wuxuu u dhexeeyaa mawjad aad u hooseeya ilaa heerkul sare oo adag.
2. Daawaynta habboon: Dooro noocyo kala duwan oo dawooyin kala duwan ah, nidaamka resin epoxy waxaa lagu daweyn karaa inta u dhaxaysa heerkulka 0 ~ 180 ℃.
3. Xabag adag: Jiritaanka polar hydroxyl iyo ether bond ee silsiladda molecular ee xabagta epoxy waxay ka dhigtaa mid aad ugu dheggan walxo kala duwan. Gaabinta resin epoxy waa mid hooseeya marka la daaweynayo, iyo diiqada gudaha ee ka dhalata waa yar tahay, taas oo sidoo kale gacan ka geysaneysa hagaajinta xoogga adhesion.
4. Gaabinta hoose: falcelinta u dhaxaysa xabagta epoxy iyo wakiilka daawaynta waxa lagu fuliyaa iyada oo si toos ah falcelinta isku darka ama giraanta-furan polymerization falcelinta ee epoxy group 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 resins phenolic, waxay muujinayaan gaabin aad u hooseeya (in ka yar 2%) inta lagu jiro habka daawaynta.
5. Guryaha makaanikada: Nidaamka xajinta epoxy ee la daweeyay wuxuu leeyahay sifooyin farsamo oo aad u fiican.
