I-Pretreatment E-coat Painting System E-coating Line

I-Cathodic epoxy electro-coatingiwuphawu lokumelana nokugqwala. Isetshenziswa kakhulu embonini yezimoto nezingxenye zezimoto, ihlinzeka ngesifutho sikasawoti esisezingeni eliphakeme, umswakama kanye nokumelana nokugqwala kwe-cyclic. Kodwa-ke, ubuchwepheshe be-cathodic epoxy ngokuvamile budinga ijazi eliphezulu ukuze livikelwe ekukhanyeni kwelanga. Izingubo zohlobo lwe-epoxy ezinuka kamnandi zithambekele ekuchakeni futhi zicekelwe phansi yizingxenye ze-UV zokukhanya kwelanga.

I-Cathodic acrylic electro-coatingitholakala ngezinhlobonhlobo zezicwebezelisi nemibala ukuze kwandiswe ukuqina kwangaphandle, ukugcinwa kweglosi, ukugcinwa kombala nokuvikela ukugqwala. Le mikhiqizo isetshenziswa njengesiphetho esinejazi elilodwa embonini yezolimo, utshani nengadi, izinto zikagesi, kanye nezimboni zokupholisa umoya.

Ama-electrocoatings e-Cathodic acrylic ngokuvamile asetshenziswa ezinhlelweni lapho kokubili ukuqina kwe-UV nokuvikelwa kokugqwala kuma-substrates anensimbi (insimbi) efiswayo. I-cathodic acrylics nayo isetshenziselwa izinhlelo zokusebenza lapho imibala ekhanyayo ifunwa khona.

Inqubo ye-electrocoat ingahlukaniswa izigaba ezine ezihlukene:

• Ukwelashwa kusengaphambili

• Ithangi le-e-coat kanye nempahla ehambisanayo

• Thumela ukugeza

• Ihhavini yokuhlanza

Enqubweni evamile ye-e-coat, izingxenye ziqale zihlanzwe futhi zifakwe ngaphambili nge-phosphate conversion coating ukuze kulungiselelwe ingxenye ye-electrocoating. Izingxenye zibe sezicwiliswa kubhavu kapende lapho kusetshenziswa khona amandla aqondile phakathi kwezingxenye kanye ne-electrode "yekhawunta". Upende ukhangwa inkambu kagesi engxenyeni bese ufakwa engxenyeni. Izingxenye zikhishwa ebhavini, zihlanjululwe ukuze kubuyiselwe izinto eziqinile zikapende ezingafakwanga, bese zibhakwa ukuze kulungiswe upende.

Ngaphambi kokufakwa kwefilimu yokupenda, izindawo eziningi zensimbi zithola ukwelashwa kusengaphambili okuvamise ukubandakanya ukumbozwa kokuguqulwa.

Inqubo evamile yokwelashwa kwangaphambili kwe-e-coat iqukethe izinyathelo ezilandelayo:

1) Ukuhlanza (isigaba esisodwa noma ngaphezulu)

2) Ukugeza

3) Conditioning

4) Ukuguqulwa kokugqoka

5) Ukugeza

6) Ngemva kokwelashwa

I-7) Ukugeza ngamanzi ahlanzekile.

Izinqubo ze-Phosphating zingahlukaniswa zibe izinhlobo ezimbili: i-iron phosphate ne-zinc phosphate. I-iron phosphate kube yinqubo yokukhethwa kwezicelo lapho ukucatshangelwa kwezindleko kukonke kudlula izidingo zokusebenza. Njengoba ama-iron phosphates ewugqinsi oluncane kunama-zinc phosphates futhi aqukethe i-ion yensimbi ye-substrate ecutshungulwayo, ahlinzeka ngokuncishiswa kokumelana nokugqwala uma kuqhathaniswa nohlelo lwe-zinc phosphate. Kodwa-ke, njengoba imingcele yendawo ezungezile iya iqina ngokuphathelene nezinsimbi ezisindayo, ukumbozwa kwe-iron phosphate kuhlanganiswe nokwelashwa okuphelele kwangemuva kungase kunikeze enye indlela esebenzayo kuyilapho zisahlangabezana nezimfuneko zokugqwala ezidingekayo. I-Zinc phosphates isiphenduke indlela yokwelashwa kapende okhethwa ngaphambili embonini yokuqedela insimbi, ikakhulukazi ngokusetshenziswa kwezinhlelo zokupenda ze-electrocoat. Isizathu siwukuthi banikeza ukumelana nokugqwala okungcono nokunamathela ngopende kunama-iron phosphates ngaphansi kwezimo ezidinga kakhulu.
