Iyini I-Acrylic Powder Coatings
acrylic powder enamathela powder babe nezakhiwo ezinhle kakhulu zokuhlobisa, ukumelana nesimo sezulu, nokumelana nokungcola, futhi babe nobulukhuni obuphezulu bobuso. Ukuvumelana nezimo okuhle. Kodwa intengo iphezulu futhi ukumelana nokugqwala kubi. Ngakho-ke, amazwe aseYurophu generalsebenzisa kahle i-polyester powder ehlanzekile (i-carboxyl-containing resin, yelashwe nge-TGIC); (i-hydroxyl-containing polyester resin yelashwa nge-isocyanate) njenge-powder ukumelana nesimo sezulu.
Ukubunjwa
I-Acrylic powder coatings yenziwe ngama-acrylic resins, pigments and fillers, izithasiselo kanye nama-ejenti okwelapha.
izinhlobo
Ngenxa yamaqembu ahlukene asebenzayo aqukethwe esakhiweni samangqamuzana, ama-acrylic resins anezinhlobo ezilandelayo:
1. I-Acrylic resin equkethe iqembu elisebenzayo le-glycidyl ether.
2. I-Acrylic resin equkethe iqembu elisebenzayo le-carboxyl.
3. I-Acrylic resin equkethe iqembu elisebenzayo le-hydroxyl.
Izimo Zokwelapha
Ngenxa yezakhiwo ezahlukene kanye namaqembu asebenzayo aqukethwe kuma-resin e-acrylic, ama-ejenti akhethiwe okwelapha kanye nezindlela zokwelapha nazo zihlukile. Ngemuva kokuxhumanisa, izakhiwo zomzimba nezamakhemikhali nazo zihlukile.
Izimo zokuphulukisa ze-acrylic powder coatings yilezi:
Ukushisa kokushisa: 180 ℃ ~ 200 ℃;
Isikhathi sokuphulukisa: 15min ~ 20min;
Izindlela zokusebenzisa i-thermosetting powder coatings zingasetshenziselwa i-acrylic powder coating.
Inqubo Yokukhiqiza
Kunezindlela ezine zokukhiqiza ze-acrylic powder coating:
Enye indlela yokuhwamuka.
Eyesibili indlela yokumisa isifutho.
Eyesithathu indlela emanzi.
Ekugcineni, kuyafana nendlela yokukhiqiza ye-epoxy powder coating.
Indlela yesine yokukhiqiza isetshenziswa kakhulu.
Inqubo imi kanje:
Ukuxuba → i-extrusion → ukuchoboza → ukusefa → ukupakisha
