Izinzuzo ze-Epoxy Polyester Hybrids Ukugqoka i-Powder

I-epoxy powder coatings esekelwe kubuchwepheshe obusha baziwa ngokuthi i-epoxy-polyester "hybrids" noma "multipolymer" izinhlelo. Leli qembu lezimbotshana eziyimpushana lingathathwa njengengxenye nje yomndeni we-epoxy, ngaphandle kokuthi iphesenti eliphezulu le-polyester elisetshenziswayo (ngokuvamile elingaphezu kwengxenye ye-resin) lenza lokho kuhlukaniswa kube ukudukisa.
Izakhiwo zalezi zingubo ezihlanganisiwe zisondelene kakhulu nama-epoxies kune-polyester, ngaphandle kokumbalwa okuphawulekayo. Babonisa ukuguquguquka okufanayo ngokomthelela kanye nokumelana nokugoba, kodwa bakhiqiza amafilimu athambile kancane.Ukumelana nokugqwala kwawo kuqhathaniswa nama-epoxies ezimweni eziningi, kodwa ukumelana kwawo nezinyibilikisi ne-alkali kuwufuzo.ralingaphansi kakhulu kuma-epoxies amsulwa.

Enye inzuzo yalawa ma-hybrids, ngenxa yethonya lengxenye ye-polyester, ukumelana okuphezulu nokubhaka okuphuzi ngokweqile kuhhavini wokwelapha. Lokhu futhi kuhumushela ekumelaneni okuthuthukisiwe kokukhanya okuphuzi kwe-ultraviolet. Lezi zinhlelo zizoqala ukushosho ngokushesha njenge-epoxy kodwa, ngemva kokuchakiswa kokuqala, ukuwohloka kuhamba kancane futhi ukuguquguquka kombala kubi kakhulu kunezimpushana ze-epoxy ezingashintshiwe.

Enye inzuzo ye-epoxy/polyester powder coatings izici zabo ezinhle ze-electrostatic spray. Angasetshenziswa ngokusebenza kahle kakhulu kokudlulisa futhi abonise ukungena okuhle emakhoneni nasezinsikeni.Ingxube ye-epoxy polyester ngokuqinisekile kufanele icatshangelwe kanye nomndeni we-epoxy ukuze ifilimu encane isetshenziswe ekupheleni kokuhlobisa. Izicelo ze-epoxy polyester hybrid zibhalwe kuMfanekiso 2-3; izakhiwo ezijwayelekile zibalwe kuMfanekiso 2-4.
