Iprofayile yeSakhiwo sangaphandle soMda wokutshiza ngepeyinti yoKutyabeka umgca

Iprofayili yokwakha iAluminiyam iprofayili yomgubo we-electrostatic ngokutshiza ithatha indlela ephezulu yombane we-electrostatic, ngenxa yeeprofayili zesakhiwo zisetyenziswa ikakhulu ngaphandle, umgubo usetyenziswa ngokubanzi kwi-thermosetting polyester yomgubo wokwaleka kunye nokusebenza kakuhle okubanzi.

Umgaqo osisiseko kukuba i-electrode kumzimba wesibhamu kunye ne-high-voltage generator edibeneyo ukuvelisa i-high-voltage electrostatic field, ukuze umoya ojikeleze i-gun corona ionization, ngenxa yendima ye-corona yombane.

Xa i-powder ifafazwe kwisibhamu, i-powder particles ingqubuzana ne-ionized air particles ukuze yenze iinqununu ezihlawuliswa kakubi, ezithunyelwa kwi-workpiece ephantsi kunye ne-airflow ukuba ibhengezwe. I-powder powder iyanyangwa ngokubhaka, ngaloo ndlela ifezekisa injongo yokugqoka.

Eyona njongo iphambili yokulungiswa komphezulu kukususa ioyile, amanqaku amancinci okukhutshwa kunye nefilimu ye-oxide yendalo kumphezulu weeprofayili ze-aluminium ukuphumeza indawo yeprofayili ecaba, kwaye emva koko ufumane ifilimu yokuguqula i-0.5-2μm nge-oxidation yeekhemikhali.

Iiprofayili kufuneka zihlanjululwe ngokucokisekileyo kwinkqubo yonyango, ukuba i-degreasing ayicocekanga, iya kubangela ifilimu yokuguqulwa engaphelelanga, ukunamathela kakubi komgangatho womgubo, umphezulu ulungele ukuba neziphene ezifana ne-concave cavities, pinholes, njl., kunye namanzi , i-oksijeni kunye ne-ion ziya kungena kwi-coating yokungena kwi-metal surface, okubangelwa ukubola kwe-substrate.

Ukunciphisa, ukungathathi hlangothi, ukuguqulwa kufuneka kuqhutywe emva kokuhlamba kwamanzi ngokucokisekileyo, ngokuqhelekileyo emva kwenkqubo nganye kufuneka ihlanjwe kabini, emva kokuguqulwa kwamanzi okuhlamba kungcono ukusebenzisa amanzi ahlambulukileyo, ngokuhlamba kwamanzi ukususa iintsalela zomhlaba, ukuze kungabikho. ukubangela ukugquma kokutshiza, ukubola, kunye nojongano kunye nesinyithi kutshatyalaliswa, ukukhawulezisa ukubola kwesinyithi phantsi kwengubo.

Emva kokulungiswa kwangaphambili, iphrofayili kufuneka yomiswe ngokukhawuleza, ukwenzela ukuba umphezulu ungagcini umswakama, ukuba umgangatho weprofayili ugcina umswakama kwi-A inkqubo yokugqoka i-powder, i-coating iya kuvelisa ama-bubbles.

Qaphela ukuba iqondo lobushushu lokumisa akufanele lidlule i-130 ℃, iqondo lobushushu liphezulu kakhulu liya kwenza ifilimu yokuguqula ilahleko enkulu yamanzi ekristale kunye nokuguqulwa, ibe yinto ekhululekile kwaye yenza ukunamathela kokunamathela kuyancipha.

Iprofayili exhonywe kwikhonkco lokuhambisa kwidokodo lokugquma umgubo, amasuntswana omgubo otyabeka kakubi kwindawo ye-electrostatic, ngoncedo lwe-adsorption yomoya ocinezelekileyo kumphezulu weprofayile, umgubo ugqunywe ngokulinganayo kumphezulu weprofayile, kwaye kungekudala. ukufikelela kwimigangatho yobugcisa echazwe kwiimfuno zobunzima befilimu.

Ukuze kuqinisekiswe umgangatho wokugquma kweprofayili, inkqubo yokutshiza i powder kufuneka igxininise ekulawuleni ubuninzi be-powder layer. I-Powder layer incinci kakhulu, ingaphantsi kwe-45μm ayikwazi ukugubungela iinqununu zokugqoka i-powder, ukwenzela ukuba iindawo ezingaphezulu zanda, ezibangele ukufana okungahambi kakuhle kwengubo. Umaleko womgubo ungqindilili kakhulu, uchaphazela umgangatho wokunyibilika komgubo; i-coating ivelisa amanqaku okuhamba kunye namaxolo e-orenji. Ukongeza, ubukhulu befilimu buchaphazela i-gloss yengubo, amandla empembelelo, kunye nokuchasana kwemozulu kunye nokunye.

Emva kokutshiza kwepowder, iprofayili ingena kwi-oven yokunyanga, kwaye i-powder adsorbed phezu kweprofayili iyanyibilika ngokufudumeza kunye nokubhaka, kwaye igesi ekwisithuba somgubo iyakhutshwa, kwaye iyancipha ngokuthe ngcembe, i-gelatinized kwaye iphiliswe. kwifilimu.

Inkqubo yokunyanga yinkqubo ebalulekileyo yokugquma umgubo, ukwakha iiprofayili ze-aluminium usebenzisa i-thermosetting polyester powder yokugqoka, iqondo lokushisa elifunekayo lokunyanga le-180 ℃, ixesha le-20min.
