Izindaba

Abaningi abasaqalayo bawela ogibeni lapho bethenga ama-rolls ahlanganiswe ngombala ngoba abaqondi izinto zabo. Ngakho-ke, iyiphi impahla elungele imiqulu ehlanganiswe ngombala?
I-substrate yamakhoyili anemibala ingaba amakhoyili abandayo noma insimbi ye-electroplated eshisayo. Nakuba ukwakheka kwekhoyili enombala kunomphumela omuhle wokunqanda ukugqwala, kusekhona izikhala ezincane ku-organic coating, okungase kuvumele umoya kanye nomswakama ukungena futhi kubangele ukugqwala kwe-substrate. Ngakho-ke, amakhoyili anemibala enziwe ngama-substrates angamboziwe anesikhathi sesevisi esifushane futhi ajwayele ukusakazeka futhi acwebezeke ngemva kokuklwejwa. I-substrate yekhoyili yensimbi enombala ngokuyinhloko iyipuleti lensimbi elikhangayo noma ingxubevange yensimbi yobuchwepheshe bepuleti lensimbi. Kweminye imigqa yokukhiqiza, inqubo yokukhiqiza yezingubo zombala ihlukaniswa ngokwelashwa kwangaphambili kwe-substrate, okokuguqulwa kwamakhemikhali (izingubo zensimbi ezingezona izinto eziphilayo), i-organic non-metallic coatings, kanye nezinqubo zokumboza okuthunyelwe.

I-1, Ukwelashwa kwangaphambili kwe-Substrate: Uma singeyona inkampani engangena ngokuqondile kunqubo yokuhlanganisa umbala womphakathi ngemuva kokukhiqizwa, amapuleti ensimbi asetshenziswa njengama-substrates angase abhekane nokugqwala (ukugqwala okumhlophe), uthuli, nokunye ukungcola ngesikhathi sokuthutha nokuthuthukiswa. . Uma lezi zingakwazi ukususwa, izinga likapende lizothinteka. Izinga lamaroli agqitshiwe ahlanganiswe ngombala kanye nokusebenza kobuchwepheshe ngokomzimba namakhemikhali kwabo bonke abafundi kuhlobene eduze nokwelashwa kwangaphambili. Ngaphezu kwalokho, ekukhiqizeni i-galvanizing, ukuze kuvinjelwe ukugqwala nokugcoba, lawa mafutha nawo ayasuswa ngaphambi kokukhiqizwa kombala wombala. Indlela yokwelapha yangaphambi kokwelashwa evame ukusetshenziswa manje indlela yokwehlisa i-alkaline yesisombululo.
2. Ifilimu yokuguqulwa kwamakhemikhali inemisebenzi emibili
Okunye ukuthuthukisa ikhono lokuvimbela ukugqwala,
Okwesibili ukuthuthukisa ukunamathela phakathi kwe-substrate ne-coating, futhi kuthuthukise ukusebenza kwe-coating ye-substrate.

Ngokuvamile kunezinyathelo ezintathu:
Enye i-phosphating, eqala ukwakha inani elikhulu lamakristalu endaweni yensimbi, bese yenza ungqimba lwefilimu ye-phosphate endaweni yensimbi ngesisombululo sikasawoti we-phosphate;
Eyesibili i-passivation nokubekwa uphawu. Ifilimu ye-phosphate isenezimbotshana ezithile, ezihlanganiswa ngamakhemikhali namachromates ukuze zakhe ifilimu evikelayo. Okwesithathu, geza ngamanzi ahlanzekile futhi ususe isixazululo se-passivation ngamanzi akhishwe usawoti noma deionized.
I-3, Izingubo ze-Organic zihlukaniswa ngokuyinhloko zibe yi-primer ne-topcoat. Izidingo zokuqala aziphezulu futhi zingasetshenziswa ngendlela eshelelayo ngombala. Kodwa-ke, ukuze kuthuthukiswe ukuphepha kolwazi lokukhiqiza, amabhizinisi aseShayina ngokuvamile asebenzisa indlela yokwemboza ehlane enemibala ye-primer nejazi eliphezulu.
Inqubo yokumboza okuthunyelwe: Inqubo yokumboza okuthunyelwe ihlanganisa ukuphrinta, ukufaka i-embossing, ifilimu yokuzivikela e peelable, ukubopha, njll., okuthuthukisa izakhiwo zokuhlobisa nezokuvikela zebhodi elifakwe umbala.
