Pretreatment E-coat Painting System E-coating Line

Cathodic epoxy electro-coatingndicho chiyereso chekuramba corrosion. Inoshandiswa zvakanyanya mumaindasitiri emotokari uye emotokari zvikamu, iwo anopa yepamusoro munyu spray, humidity uye cyclic corrosion resistance. Nekudaro, iyo cathodic epoxy tekinoroji kazhinji inoda kuti topcoat ichengetedzwe kubva kuchiedza chezuva. Iyo inonhuhwirira epoxy-mhando yekujairira inonyanya kuita chalking uye kuderedzwa neiyo UV zvikamu zvechiedza chezuva.

Cathodic acrylic electro-coatinginowanikwa mumhando dzakasiyana-siyana dze glosses uye mavara kuti awedzere kusimba kwekunze, kubwinya kwekuchengetedza, kuchengetedza kwemavara uye kuchengetedzwa kwekuora. Zvigadzirwa izvi zvinoshandiswa seyejasi-rimwe kupera mune zvekurima, lawn uye gadheni, zvekushandisa, uye air-conditioning maindasitiri.

Cathodic acrylic electrocoatings anowanzo shandiswa mumashandisirwo apo zvese zviri zviviri kusimba kweUV uye kuchengetedzwa kwekuora pane ferrous substrates (simbi) inodiwa. Iyo cathodic acrylics inoshandiswawo mumashandisirwo ayo mavara akareruka anodiwa.

Iyo electrocoat process inogona kukamurwa kuita zvikamu zvina zvakasiyana:

• Kurapwa

• E-coat tangi uye ancillary midziyo

• Tumira sukurudza

• Kupisa ovheni

Mune yakajairwa e-coat process, zvikamu zvinotanga kucheneswa uye kufanogadziriswa nefosifati yekushandura coating kugadzirira chikamu che electrocoating. Zvikamu zvinobva zvanyudzwa mubhati rekugezesa pendi umo yakananga ikozvino inoshandiswa pakati pezvikamu uye "counter" electrode. Paint inokwezva nemunda wemagetsi kune chikamu uye inoiswa pane chikamu. Zvikamu zvinobviswa mubhati, zvosukurudzwa kuti zvidzorere zvinyoro zvependi zvisina kuiswa, zvozobikwa kuti zvirape pende.

Usati wapenda firimu rekushandisa, nzvimbo zhinji dzesimbi dzinogashira pretreatment iyo inowanzo sanganisira yekutendeuka coating.

Iyo yakajairika pretreatment process ye e-coat ine anotevera matanho:

1) Kuchenesa (imwe kana mamwe nhanho)

2) Rinsing

3) Conditioning

4) Kushandura kupfeka

5) Rinsing

6) Mushure mekurapa

7) Deionized mvura yekugeza.

Maitiro ePhosphating anogona kupatsanurwa kuita marudzi maviri: iron phosphate uye zinc phosphate. Iron phosphate yanga iri nzira yesarudzo yezvishandiso uko kutariswa kwemutengo wese kunodarika zvinodiwa kuita. Sezvo iron phosphates iri machira matete kupfuura zinc phosphates uye iine chete iyo simbi ion ye substrate iri kugadziriswa, inopa kuderedzwa kwekushomeka kwekushomeka kana ichienzaniswa nezinc phosphate system. Nekudaro, nekurambidzwa kwezvakatipoteredza kuri kuwedzera kusimba maererano nesimbi inorema, iyo iron phosphate coating yakasanganiswa nekunyatso rapwa kwepost inogona kupa imwe nzira inoshanda uchiri kusangana nezvinodiwa zvekuora. Zinc phosphates yave yakasarudzika kurapwa kwepaint muindasitiri yekupedzisa simbi, kunyanya nekushandiswa kwe electrocoat pendi masisitimu. Chikonzero ndechekuti ivo vanopa zvirinani kuomarara uye kunamatira kwepende kupfuura iron phosphates pasi pemamiriro akanyanya kudiwa.
