Umehluko kanye nokusetshenziswa kwe-galvanizing, electrophoresis kanye nokufafaza
Embonini yokucubungula insimbi, inqubo yokwelapha engaphezulu ithinta ngokuqondile ukusebenza komkhiqizo wokunqanda ukugqwala, ukumelana nokugqoka kanye nobuhle. Kunezindlela ezintathu ezivamile zokwelapha ebusweni: galvanizing, electrophoresis kanye sishaye. Ngayinye inezici zayo futhi ifanele izimo ezihlukene zohlelo lokusebenza. Sizoqhathanisa futhi sihlaziye izici, izinzuzo kanye nokubi kanye nezinkambu zokusetshenziswa zalezi zinqubo ezintathu. Idatha ingeyereferensi kuphela.
1. Ukugalela
Isingeniso Senqubo
I-galvanizing inqubo evimbela ukugqwala ngokumboza indawo yensimbi ngongqimba lwezinc, ikakhulukazi okuhlanganisa i-hot-dip galvanizing kanye ne-electro-galvanizing.
Izici Eziyinhloko
I-Hot-dip galvanizing: cwilisa umkhiqizo wensimbi kwisisombululo se-zinc esisezingeni eliphezulu ukuze wenze ungqimba lwezinc olufanayo ebusweni balo.
● Ugqinsi lwengqimba ye-Zinc: 50-150μm
● Ukumelana nokugqwala: kuhle kakhulu, kulungele izindawo ezingaphandle
● Isimo sobuso: izimbali ezimahhadlahhadla, ezimpunga, nezinc zingase zivele
I-Electrogalvanizing
Ungqimba lwezinc lufakwa endaweni yensimbi ngenqubo ye-electrolytic ukuze kwakhiwe ungqimba oluncane oluvikelayo.
Ubukhulu bengqimba ye-Zinc: 5-30μm
Ukumelana nokugqwala: Okujwayelekile, kulungele izindawo zasendlini
Isimo sobuso: bushelelezi, ukukhanya okuphezulu
Izimo ezisebenzayo
● I-hot-dip galvanizing: izakhiwo zebhuloho,izisekelo zokwakha, imibhoshongo kagesi, amapayipi angaphandle, imishini esindayo, njll.
● I-Electrogalvanizing: izinto zokubopha ezincane, izingxenye zensimbi zasendlini, izindlu zemishini yasendlini, izingxenye zezimoto, njll.
Izinzuzo kanye nokubi
Izinzuzo: ikhono eliqinile lokulwa nokugqwala, ukonga nokuqina, i-hot-dip galvanizing ilungele izindawo ezinokhahlo.
Ububi: I-Electrogalvanizing inamandla abuthaka uma kuqhathaniswa wokunqanda ukugqwala, futhi ingaphezulu le-hot-dip galvanizing ilukhuni, okungase kuphazamise ukubukeka.
2. Electrophoretic Coating
Isingeniso Senqubo
I-Electrophoretic coating iyinqubo yokuhlanganisa esebenzisa inkambu kagesi ukwenza upende unamathele ngokulinganayo endaweni yensimbi. Isetshenziswa kabanzi ezimbonini zezimoto, zasendlini nakwezinye izimboni.
Izici eziyinhloko
● Ukwamukela ubuchwepheshe be-anodic noma i-cathodic electrophoresis, i-coating ifana futhi izinga lokusebenzisa ukunamathela liphezulu.
● Ukwenza i-organic coating eminyene, ngokuvamile esetshenziswa ne-phosphating noma i-galvanizing treatment ukuze kuthuthukiswe ukusebenza kwe-anti-corrosion.
● Ubukhulu befilimu: 15-35μm (iyalungiseka)
● Umbala: uyazikhethela (imvamisa emnyama nokumpunga)
Izimo ezisebenzayo
● Izingxenye zemoto (uhlaka, isistimu yokumiswa, i-brake caliper)
● Izingxenyekazi zensimbi yokwakha (abakaki bensimbi, izixhumi, izifakelo zamapayipi)
● Ama-elevator rails, izingxenye zemishini
Izinzuzo: ukunamathela okufanayo, ukunamathela okuqinile, ukusebenza kahle kwe-anti-corrosion, ukuvikelwa kwemvelo nokonga amandla
Ukungalungi: ukugeleza kwenqubo eyinkimbinkimbi, izidingo eziphezulu zemishini, nezindleko eziphezulu zokuqala
3. Ukufafaza
Isingeniso Senqubo
Ukufafaza kuhlukaniswe ngokufafaza okuyimpushana (i-electrostatic spraying) kanye ne-liquid spraying. Ukufuthwa kwempushana kusebenzisa isenzo se-electrostatic ukwenza i-powder adsorb endaweni yensimbi futhi kwakhe ukunamathela ngokuphulukisa izinga lokushisa eliphezulu; ukufutha okuwuketshezi kusebenzisa isibhamu sokufutha ukuze sifafaze upende ngokuqondile, okuvamile ezigcawini ezidinga imibala ecebile.
Izici eziyinhloko
Ukufafaza nge-powder:
● Ukujiya kokugqoka: 50-200μm
● Ukumelana nokugqokwa okuhle kakhulu nokumelana nokugqwala, kulungele izindawo zangaphandle nezimboni
Ivumela imvelo, i-solvent-free
Umdwebo wesifutho samanzi:
● Ukuqina kwe-coating: 10-50μm
● Imibala ecebile, efanelekile ukuhlobisa okuhle
● Ukulungiswa kwendawo kungenziwa
Izimo ezisebenzayo
● Ukufutha ngompushana: amabakaki okwakha, ama- guardrail, izindlu zikagesi, izinto zokusebenza zangaphandle
● Umdwebo wesifutho samanzi: izinto zokusebenza zasendlini eziphezulu, imikhiqizo yensimbi yokuhlobisa, izimpawu
Izinzuzo: Ukufafaza ngempushana kunombala oshubile nokuqina okuhle; liquid spray umdwebo unemibala ecebile kanye anhlobonhlobo izicelo
Ukubi: Ukufafaza ngempuphu akukwazi ukulungiswa endaweni, futhi umdwebo wesifutho esiwuketshezi awuhambisani nemvelo.
Iziphakamiso zokukhetha:
● Idinga ukusebenza okuqinile okunqanda ukugqwala (okufana namabhuloho, imibhoshongo yamandla, izakhiwo zensimbi yekheshi) → Ukufakwa uthayela kwediphu elishisayo
● Idinga indawo ebushelelezi kanye ne-anti-corrosion evamile (njengamafasteners, izingxenye zezimoto) → I-Electrogalvanizing
● Idinga ukunamathela okufanayo nokumelana nokugqwala okuphezulu (njengama-elevator guide rails, izingxenye zezimoto) → I-Electrophoretic coating
● Idinga ukumelana nokuguga okuhle nokumelana nesimo sezulu (njengabakaki bokwakha, izindlu zikagesi) → Ukufafaza ngempuphu
● Udinga ukubukeka okumibalabala nokuhlobisa okuhle (njengezinto zikagesi zasendlini, amabhodi ophawu) → Ukupenda kwesifutho esiwuketshezi
Izinqubo ezahlukene zinezici zazo. Ukukhetha indlela yokwelapha engaphezulu efanele kumele kusekelwe endaweni osetshenziswa kuyo umkhiqizo, izidingo zokusebenza kanye nokucatshangelwa kwezindleko. Imikhiqizo ye-Xinzhe Metal inganikeza izixazululo zokwelapha ezisezingeni eliphezulu ngokwezidingo zamakhasimende, wamukelekile ukubonisana!
