Aluminium profiles poda spray coating line

Upfu hwekuputira uchishandisa musimboti wekupfapfaidza kwemagetsi ehupfu hwakaoma adsorption pane simbi aruminiyamu profiles, mushure me200 ℃ yakanyanya tembiricha barbecue, hupfu hwakaporeswa kuita mutsetse ungangoita 60 microns gobvu rakasimba rinopenya. Itai kuti chigadzirwa chepamusoro chakatsvedza uye kunyange ruvara nechakasimba asidi kuramba, alkali kuramba, kukanganisa kuramba, kupfeka kuramba, anogona kutsungirira yakasimba ultraviolet nemwaranzi uye asidhi mvura kukurwa mvura kwenguva yakareba, haaoneki coating chalking, kupera, peeling uye zvimwe zviitiko. Powder coated aluminium profiles ine hupenyu hwebasa hwemakore makumi matatu pasi pemamiriro akajairika. Kuvhara kwayo kwepamusoro mumakore 5-10 kuve nechokwadi kuti ruvara haruna kupera, harushanduki ruvara, harutseki. Kuramba kwayo mamiriro ekunze uye ngura zviri nani pane zvakajairwa aruminiyamu mavara akasiyana.

Loading → Pretreatment → Kuomesa Hunyoro → Kutonhodza → Kupfapfaidza hupfu (Reciprocator) → Kurapa hupfu (kutenderera kwemhepo inopisa) → Kutonhodza → Kuburutsa

Pre-atreatment process quality inobata zvakananga kunaka kwepoda coating film, pre-atreatment haina kunaka, zvichiita kuti zvive nyore kubvisa firimu, bubbling nezvimwe zviitiko.

For sheet simbi stamping zvikamu zvinogona kushandiswa kemikari pretreatment nzira. Mazhinji e ngura kana pamusoro pevhu rakakora workpiece, kushandiswa kwejecha, kuputika kwepfuti uye dzimwe nzira dzemuchina kubvisa ngura, asi mechanical descaling inofanira kuve nechokwadi kuti pamusoro pechishandiso chakachena uye chisina kuenzana.

Zvinoenderana nehuwandu hwekuremara mune workpiece scraping conductive putty, mushure mekuomeswa nesandpaper kukuya yakatsetseka, unogona kuita inotevera maitiro.

Kana pane zvimwe zvikamu zve workpiece zvisingadi kupfekedza, zvinogona kuvharwa nekudzivirira kwekudzivirira, nezvimwewo, vasati vatanga kupisa kuti varege kupfapfaidza pamucheka.

Preheating kazhinji haidiwi. Kana iyo yakakora coating ichidikanwa, iyo workpiece inogona preheated kusvika 100-160 ℃, iyo inogona kuwedzera ukobvu hwejasi.

Electrostatic jenareta kuburikidza nepfuti muromo wetsono ye electrode kuenda kunzvimbo yebasa yenzvimbo yekuburitsa yakakwira-voltage electrostatic (negative), iyo yakakwira-voltage electrostatic kubva mupfuti yehupfu uye yakamanikidzwa mhepo musanganiswa pamwe neelectrode yakatenderedza. air ionization (negative charge). The workpiece kuburikidza anoturikwa kuburikidza conveyor link pasi (grounding danda), kuitira kuti pfuti uye workpiece kuumba yemagetsi munda pakati upfu mumagetsi munda simba uye compressed mhepo kumanikidzwa pasi kaviri kusunda pamusoro pemvura workpiece, kuvimba ne electrostatic kukwezva pamusoro peiyo workpiece kuti iite layer yeuniform coating.

Mushure mekumwaya workpiece kuburikidza neketani yekutakura mu180 ~ 200 ℃ yekubikira kamuri yekudziya, uye ramba uchidziya kwenguva inoenderana, (15-20 maminitsi) kuitira kuti kunyunguduka, kuenzanisa, kurapa, kuitira kuti tiwane workpiece pamusoro pekuita isu. kuda. (Mapoda akasiyana akasiyana mukupisa kwekubika uye nguva). Izvi ndizvo zvatinofanira kucherekedza mukuita kurapa.

Mushure mekuputirwa nekuporeswa, bvisa chidziviriro uye cheka maburrs.

Mushure mekuporesa iyo workpiece, iyo huru yezuva nezuva yekuongorora chitarisiko (ingave yakatsetseka uye yakajeka, ine kana isina zvimedu, shrinkage uye humwe hurema) uye ukobvu (kutonga mu55 ~ 90μm). Kune zvakaonekwa zvirema zvakaita sekudonha, pinho, bruise, bubble, nezvimwe, iyo workpiece ichagadziriswa kana kupfapfaidzwa zvakare.

Mushure mekuongorora, zvigadzirwa zvakapedzwa zvinorongedzwa uye zvinoiswa murori yekutakura uye bhokisi rekuchinja, uye zvakapatsanurwa kubva kune mumwe nemumwe nekunyorovesa kurongedza cushioning zvinhu senge bepa refuro uye bubble firimu kudzivirira kukwenya uye abrasion.
