I-Thermosetting powder coating isetshenziswa kabanzi kakhulu

I-Thermosetting i-powder coating asetshenziswa inqubo yokufutha ye-electrostatic, ashisiswe ezingeni lokushisa elidingekayo futhi ephulukisiwe futhi ngokuyinhloko akhiwa ama-resin ama-molecular weightsolid aphakeme kakhulu kanye ne-crosslinker.Ukwakhiwa kwezimpushana ze-thermosetting kuqukethe ama-resins ayinhloko: I-Epoxy, i-Polyester, i-Acrylic.

Lawa ma-resin ayisisekelo asetshenziswa ngama-crosslinkers ahlukene ukukhiqiza izinto ezahlukahlukene zempushana. Ama-crosslinker amaningi, noma ama-ejenti okwelapha, asetshenziswa kuma-powder coatings, okuhlanganisa ama-amine, ama-anhydrides, ama-melamine, nama-isocyanate avinjiwe noma angavinjelwe.Ezinye izinto zisebenzisa i-resin engaphezu kweyodwa kumafomula ayingxube.

Uma i-thermoset powder isetshenziswa futhi ingaphansi kokushisa izoncibilika, igeleze futhi inqamule amakhemikhali ukuze yenze ifilimu eqediwe.Ukusabela kwamakhemikhali emjikelezweni wokwelapha kudala inethiwekhi ye-polymer enikeza ukumelana okuhle kakhulu ekuqhekekeni kwe-coating. Impushana ye-thermoset eselashiwe futhi yahlangana ngeke inyibilike futhi igeleze futhi uma ingaphansi kokushisa okwesibili.
