Faa’iidooyinka looxa xabagta epoxy

1. adhesion xoog leh

Kooxaha dabiiciga ah ee hydroxyl polar iyo curaarta ether ee silsiladda molecular ee resins epoxy waxay ka dhigaan 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.

2. Yaraynta xooggan

Dareen-celinta u dhaxaysa xabagta epoxy-ga iyo wakiilka daawaynta ee la isticmaalo waxa lagu fuliyaa fal-celin toos ah oo dheeraad ah ama falcelinta polymerization-ka-furay ee kooxaha epoxy-ga ee molecule-ka xabagta, oo aan biyo ama alaab kale oo kacsani soo baxayn. 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.

3. Waxqabadka korontada

Nidaamka xabagta epoxy ee la daweeyay waa walxo dahaadhid aad u wanaagsan oo leh sifooyin koronto oo sarreeya, caabbinta daadinta dusha sare, iyo iska caabinta arc.

4. Guryaha makaanikada

Nidaamka resin epoxy ee la daweeyay wuxuu leeyahay sifooyin farsamo oo aad u wanaagsan.

5. Degganaanta kiimikada

Guud ahaan, nidaamka resin epoxy la daaweeyay waxa uu leeyahay iska caabin alkali heer sare ah, caabin aashitada 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.

6. xasilloonida cabbirka

Isku darka qaar badan oo ka mid ah guryaha kor ku xusan waxay siinayaa nidaamka resin epoxy-ga oo heersare ah xasillooni iyo adkeysi heersare ah.

7. caabbinta caaryada

Nidaamka resin epoxy ee la daweeyay ayaa u adkeysan kara caaryada badankooda waxaana loo isticmaali karaa xaaladaha kulaylaha adag.
