I-Dip Powder Coating Futhi I-spray Powder Coating

1. Imiqondo ehlukene

1) Futha i-Powder coating:

I-spray Powder coating iyindlela yokwelapha engaphezulu ehlanganisa ukufafaza impushana emkhiqizweni. Impushana ngokuvamile ibhekisela embotsheni ye-thermosetting powder. Ingaphezulu lemikhiqizo embozwe ngempushana ilukhuni futhi ibushelelezi kunemikhiqizo efakwe idiphu. Amajeneretha e-electrostatic asetshenziselwa ukushaja impushana, esuke ikhangwa phezu kwepuleti lensimbi. Ngemuva kokubhaka ku-180-220 ℃, impushana iyancibilika futhi inamathele endaweni yensimbi. Imikhiqizo ehlanganiswe ngempushana ivame ukusetshenziselwa ukusetshenziswa kwangaphakathi, futhi ifilimu yopende inomphumela oyisicaba noma we-matte noma wobuciko.

2) I-Dip powder coatings:

I-Dip powder coating ihlanganisa ukushisisa insimbi nokuyimboza ngokulinganayo ngempushana yepulasitiki ukuze kwakhiwe ifilimu yepulasitiki, noma ukufudumeza nokucwilisa insimbi kusixazululo sokumboza idiphu ukuze kuphole futhi kwakhiwe ifilimu yepulasitiki endaweni yensimbi. Impushana ngokuvamile ibhekisela kuyo i-thermoplastic powder coating. I-Dip coating ingahlukaniswa ibe i-hot dip coating kanye ne-cold dip coating, depeukuthola ukuthi ukufudumeza kuyadingeka yini, kanye ne-liquid dip coating kanye ne-powder dip coating, depeukugxila ezintweni ezisetshenziswayo.

2. Izindlela ezihlukene zokucubungula

1) Kunezinhlobo ezahlukene ze-spray powder coating, njenge-acrylic powder, i-polyester powder, ne-epoxy polyester powder. I-spray powder coating inekhwalithi ephezulu yomkhiqizo nesisindo kune-dip powder coating, kodwa ingaphezulu lomkhiqizo lihle futhi libushelelezi kuzo zombili izindlela.

2) I-Dip coating ishibhile kune-spray powder coating ngoba intengo ye-dip coating powder iphansi kunaleyo yensimbi. I-Dip powder coating inezinzuzo zokunqanda ukugqwala nokugqwala, ukumelana ne-asidi ne-alkali, ukumelana nomswakama, ukugqumisa, ukuthinta kahle, ukuvikelwa kwemvelo, nokuphila isikhathi eside kwesevisi. Ukujiya kwe-Dip coating kuvame ukujiya kune-spray powder coating, enogqinsi olungaphezu kwama-microns angama-400 uma kuqhathaniswa nama-microns angama-50-200 wokumboza ngempushana.

1) Dip coating powders:

① I-Civil powder coating: isetshenziselwa kakhulu ukumboza amarack ezingubo, amabhayisikili, obhasikidi, izitsha zasekhishini, njll. Anokugeleza okuhle, okucwebezelayo, nokuqina.

②Imbozo yempushana yobunjiniyela: isetshenziselwa ukumboza izinsimbi zomgwaqo onguthelawayeka nezitimela, ubunjiniyela bakamasipala, amathuluzi namamitha, amagridi esuphamakethe, amashalofu eziqandisini, izintambo, nezinto ezixubile, njll. Zinokuqina okuqinile nokungagqwali.

2) Isimiso se-Dip coating:

I-Dip coating iyinqubo yokushisa ehlanganisa ukushisa kwangaphambili kwensimbi, ukucwiliswa kwisisombululo sokumboza, nokuyiphulukisa. Ngesikhathi sokucwiliswa, insimbi evuthayo inamathela ezintweni ezizungezile. Lapho insimbi ishisa kakhulu, isikhathi sokucwilisa siba side, kanye nokujiya kokunamathela. Izinga lokushisa nokuma kwesisombululo sokumboza kunquma inani le-plasticizer elinamathela ensimbi. I-Dip coating ingakha izimo ezimangalisayo. Inqubo yangempela ihilela ukungeza ukumbozwa kwempushana esitsheni esinezimbotshana ezingaphansi (ithangi lokugeleza), elisuke linyakaziswa umoya ocindezelwe ophathwa ngesifutha ukuze kuzuzwe "isimo esinoketshezi", okwenza impushana ekahle esabalaliswe ngokufanayo.

3. Ukufana 

Zombili izindlela zokwelapha ezingaphezulu. Imibala yazo zombili izindlela ingaba phuzi, obomvu, omhlophe, oluhlaza okwesibhakabhaka, oluhlaza okotshani, nomnyama.
