Kunze Kwekuvaka Profile Powder Spray Paint Coating Line

Aluminium yekuvaka mbiri electrostatic poda yekupfapfaidza inonyanya kutora yakakwira-voltage electrostatic nzira, nekuda kweiyo maprofiles ekuvaka anonyanya kushandiswa kunze, hupfu hunowanzo shandiswa mu thermosetting polyester poda coating ine yakanaka yakazara kuita.

Nheyo yakakosha ndeyekuti iyo electrode pamutumbi wepfuti uye iyo yakakwira-voltage jenareta yakabatana kuti ibudise yakakwirira-voltage electrostatic munda, kuitira kuti mhepo yakatenderedza pfuti corona ionization, nekuda kwebasa rekona yemagetsi munda.

Kana hupfu hwapfapfaidzwa kubva mupfuti, zvimedu zvehupfu zvinodhumhana neiyo ionized air particles kuti iite negative charged particles, izvo zvinozotumirwa kune yakadzika workpiece nemhepo inoyerera kuti adsorbed. Iyo poda yekuputira inobva yaporeswa nekubika, nokudaro kuzadzisa chinangwa chekuputira.

Chinangwa chikuru chekugadzirisa kwepamusoro ndechekubvisa mafuta, madiki eextrusion mamaki uye echisikigo oxide firimu pamusoro pearuminiyamu profiles kuti iwane yakapfava chimiro chepamusoro, uye wozowana 0.5-2μm yekushandura firimu kuburikidza nemakemikari oxidation.

Maprofiles anofanirwa kucheneswa zvakakwana mukuita pretreatment process, kana degreasing isina kuchena, inokonzeresa kusakwana kutendeuka firimu, kusanamira zvakanaka kwehupfu layer, iyo yepamusoro inotapukirwa nekuremara senge concave cavities, pinholes, nezvimwewo, nemvura. , okisijeni uye ions ichapinda mukati mekuputira kupinda mukati mesimbi, zvichiita kuti kuparara kwe substrate.

Degreasing, neutralization, shanduko inofanira kuitwa mushure mekunyatsogeza kwemvura, kazhinji mushure mekuita imwe neimwe inofanira kushambidzwa kaviri, mushure mekushandurwa kwemvura yekugeza kwakanakisisa kushandisa mvura yakachena, kuburikidza nekushambidza kwemvura kubvisa zvisaririra zvepasi, kuitira kuti zvisadaro. kuita kuti spray coating blistering, staining, uye interface ine simbi inoparadzwa, kukurumidza kuparara kwesimbi pasi pekuvhara.

Mushure mekugadzirisa, iyo purogiramu inofanira kuomeswa pakarepo, kuitira kuti nzvimbo irege kuchengetedza unyoro, kana chimiro chepamusoro chichichengetedza unyoro muA powder coating process, kupfekedza kunobudisa mabhubhu.

Ziva kuti tembiricha yekuomesa haifanire kudarika 130 ℃, tembiricha yakanyanyisa kuchaita kuti bhaisikopo rekutendeuka ranyanya kurasikirwa nekristaro yemvura uye shanduko, rive rakasununguka uye riite yekunamira kwekunamatira kuderera.

Profile yakaturikwa mucheni yekutakura mupowder coating booth, yakashata yaipomerwa poda yekuputira zvimedu mumunda we electrostatic, nerubatsiro rwekumanikidza mweya drive adsorption pamusoro peiyo profil, hupfu hwakafanana hwakaputirwa pamusoro peiyo profil, uye munguva pfupi. svika kune tekinoroji zviyero zvakatarwa mune zvinodiwa zvekukora kwefirimu.

Kuti uve nechokwadi chekuputira chimiro, iyo poda yekupfapfaidza maitiro inofanirwa kutarisa kudzora ukobvu hwehupfu hwehupfu. Powder layer yakanyanya kutetepa, isingasviki 45μm haigoni kuvhara zvidimbu zvehupfu, kuitira kuti zvimedu zvepamusoro zviwedzere, zvichiita kuti pave nekusafanana kwehuputi. Powder layer yakanyanyisa, inokanganisa kunyungudika kwehupfu; iyo yekupfekedza inoburitsa mavara ekuyerera uye peel orenji. Mukuwedzera, iyo firimu ukobvu inokanganisawo kupenya kwejasi, kusimba kwesimba, uye kuramba mamiriro ekunze uye zvichingodaro.

Mushure mekupfapfaidza hupfu, iyo mbiri inopinda muchoto chekurapa, uye hupfu hwakashongedzwa pamusoro peiyo profil inonyungudutswa kuburikidza nekupisa uye kubheka, uye gasi riri mugomba rehupfu rinoburitswa, uye zvishoma nezvishoma rinosimudzwa, gelatinized uye kurapwa. mufirimu.

Kurapa maitiro ibasa rakakosha rekuputira hupfu, kuvaka aluminium profiles uchishandisa thermosetting polyester poda coating, inodiwa yekurapa tembiricha ye180 ℃, nguva 20min.
