Sidee ku saabsan guddiga epoxy fiberglass?

1. 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.

2. Daawaynta ku habboon. Adigoo isticmaalaya dawooyin kala duwan, nidaamka resin epoxy ku dhawaad ​​waxaa lagu daweyn karaa inta u dhaxaysa heerkulka 0～180℃.

3. adhesion xoog leh. Kooxda hydroxyl polar ee dabiiciga ah iyo dammaanadda ether-ka ee silsiladda molecular ee resin epoxy waxay ka dhigayaan inay ku dhegganaadaan 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. Dareen-celinta u dhaxaysa xabagta epoxy-ga iyo wakiilka daawaynta ee la isticmaalo waxa lagu fuliyaa falcelin toos ah oo dheeraad ah ama falcelinta polymerization-ka-furay ee kooxaha epoxy-ga ee molecule-ka resin-ka, oo aan biyo ama alaab kale oo kacsan la sii dayn. Marka la barbar dhigo resins polyester-ka aan dheregsanayn iyo xabagta phenolic, waxay muujinayaan hoos u dhac aad u hooseeya (in ka yar 2%) inta lagu jiro daawaynta.

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