Iphrofayela Yokwakha Yangaphandle I-Powder Spray Paint Coating Line

Eminyakeni yamuva nje, ngokuhlukahluka kanye nokwenza kube ngokwakho izakhiwo, ingaphezulu lamaphrofayili e-aluminium ezakhiwo liyathuthuka libheke ekuhlukaniseni imibala. Inqubo yokufafaza ngempuphu ye-electrostatic isebenzisa ubuchwepheshe obuluhlaza bokuvikela imvelo, obubonakala ngokonga amandla, ukuphepha kanye nokungcola okuphansi.

Ukufakwa okungaphezulu kwamaphrofayili anombala we-aluminium akhiqizwayo kunezinzuzo zokuhlukahluka kombala, umbala ofanayo, ukumelana nokugqwala, ukumelana nomthelela, ukunamathela okuqinile, ukumelana nesimo sezulu esihle, futhi iminyaka yokuphila iphakeme ngokuphindwe kabili kunaleyo yamaphrofayili ajwayelekile e-aluminium anodized.

I-COATING YETHU ingenza ngokwezifiso umugqa wonke wokukhiqiza. Uma uthanda, sicela usithinte.

imininingwane yomkhiqizo

Isimiso

Iphrofayili yesakhiwo se-Aluminium i-electrostatic powder spraying ikakhulukazi isebenzisa indlela ye-electrostatic ephezulu, ngenxa yamaphrofayili wokwakha asetshenziswa kakhulu ngaphandle, impushana ivame ukusetshenziswa ku-thermosetting polyester powder enamathela ngokusebenza okuhle okuphelele.

Isimiso esiyisisekelo ukuthi i-electrode emzimbeni wesibhamu kanye nejeneretha ye-high-voltage exhunywe ukukhiqiza insimu ye-electrostatic high-voltage, ukuze umoya ozungeze i-ionization ye-gun corona, ngenxa yendima yenkundla kagesi ye-corona.

Uma impushana ifuthwa ngesibhamu, izinhlayiya zempushana zishayisana nezinhlayiya zomoya we-ionized ukuze zenze izinhlayiya ezinecala elibi, bese zithunyelwa endaweni yokusebenza ephansi kanye nokugeleza komoya ukuze kukhangiswe. Khona-ke i-powder yokugcoba iphulukiswa ngokubhaka, ngaleyo ndlela ifeze injongo yokugqoka.

Isibonisi somkhiqizo

I-Surface Pretreatment

Inhloso eyinhloko ye-surface pretreatment ukususa amafutha, ama-extrusion marks amancane kanye nefilimu ye-oxide yemvelo ebusweni bamaphrofayili e-aluminium ukuze kuzuzwe indawo yephrofayili eyisicaba, bese uthola ifilimu yokuguqula engu-0.5-2μm ngokusebenzisa i-chemical oxidation.

Amaphrofayili kufanele ahlanjululwe kahle enqubweni yokwelashwa, uma ukukhishwa kungahlanzekile, kuzodala ifilimu yokuguqulwa engaphelele, ukunamathela okungalungile kongqimba lwempushana, indawo engaphezulu ijwayele ukukhubazeka okufana nemigodi ye-concave, amaphinikhodi, njll, namanzi , i-oksijeni nama-ion azongena embotsheni ukuze angene endaweni yensimbi, okuholela ekugqwaleni kwe-substrate.

Ukunciphisa, ukungathathi hlangothi, ukuguqulwa kufanele kwenziwe ngemuva kokugeza kwamanzi okuphelele, ngokuvamile ngemva kwenqubo ngayinye kufanele igezwe kabili, emva kokuguqulwa kokugeza kwamanzi kungcono ukusebenzisa amanzi ahlanzekile, ngokusebenzisa ukugeza kwamanzi ukuze kukhishwe izinsalela ezingaphezulu, ukuze kungabikho. ukubangela amabhamuza, ukubola kwe-spray, futhi isixhumi esibonakalayo esinensimbi sicekeleke phansi, kusheshiswe ukugqwala kwensimbi ngaphansi kwesembozo.

Ukomisa

Ngemuva kokwelashwa, iphrofayili kufanele yomiswe ngokushesha, ukuze indawo engaphezulu ingagcini umswakama, uma indawo yephrofayili igcina umswakama ohlelweni lwe-A powder coating, ukugqoka kuzokhiqiza ama-bubbles.

Qaphela ukuthi izinga lokushisa omisiwe akufanele lidlule 130 ℃, izinga lokushisa eliphezulu kakhulu kuzokwenza ifilimu ukuguqulwa ukulahlekelwa kakhulu amanzi crystalline nokuguqulwa, ibe okuxekethile futhi wenze enamathela enamathela ukwehla.

I-Electrostatic Powder Coating

Iphrofayili ilenga kuketango lokuthutha idokodo lokumboza impushana, izinhlayiya zokumboza i-powder ezinecala elibi emkhakheni we-electrostatic, ngosizo lwe-adsorption yedrayivu yomoya ecindezelwe ebusweni bephrofayili, impushana iboshwe ngokulinganayo ebusweni bephrofayili, futhi maduze. finyelela izindinganiso zobuchwepheshe ezibalulwe ezidingweni zogqinsi lwefilimu.

Ukuze uqinisekise ikhwalithi yokugqoka iphrofayili, inqubo yokufafaza i-powder kufanele igxile ekulawuleni ukushuba kwesendlalelo se-powder. I-powder layer incane kakhulu, ingaphansi kuka-45μm ayikwazi ukumboza izinhlayiya zokumboza i-powder, ukuze izinhlayiya ezingaphezulu zande, okuholela ekufaneni okungalungile kwe-coating. I-powder layer iwugqinsi kakhulu, ithinta ukuncibilika kwempushana; ukugqoka kuveza izimpawu zokugeleza kanye nekhasi lewolintshi. Ngaphezu kwalokho, ukushuba kwefilimu nakho kuthinta isicwebezelisi se-coating, amandla omthelela, nokumelana nesimo sezulu nokunye.

Ukubhaka nokwelapha

Ngemuva kokufafaza kwe-powder, iphrofayili ingena kuhhavini yokuphulukisa, futhi i-powder adsorbed ebusweni bephrofayili iyancibilika ngokushisa nokubhaka, futhi igesi elisesikhala sempushana iyakhishwa, futhi kancane kancane iyalinganiswa, i-gelatinized futhi ilashwe. kwifilimu.

Inqubo yokwelapha iyinqubo ebalulekile yokumboza impushana, ukwakha amaphrofayili e-aluminium usebenzisa i-thermosetting polyester powder coating, izinga lokushisa elidingekayo lokuphulukisa lika-180 ℃, isikhathi esingu-20min.
