Yiziphi izinhlobo zemizimba enama-galvanized ezikhona nokuthi iyiphi ongayikhetha
Okuqukethwe
Ubuchwepheshe bokusetshenziswa okushisayo kwenza kube nokwenzeka ukuthi ekugcineni uthole umzimba onogqinsi oluyisivikelo lwama-microns angu-15-20, noma ngabe kuvela imihuzuko, i-zinc izoqala u-oxidize, kodwa hhayi isisekelo sensimbi yemoto. Indlela isetshenziswa hhayi kuphela lapho udala imoto ye-premium, ezinye izinhlobo zebhajethi nazo zicutshungulwa kahle, sikhuluma nge-Renault Logan noma i-Ford Focus.
Abanikazi bezimoto banomusa kakhulu kumngane wabo onamasondo amane, ngoba njalo ngemva kweminyaka embalwa akuwona wonke umuntu ongakwazi ukukhokhela imoto. Ukuze ungakhathazeki ngomphumela olimazayo wokugqwala, ukushiya imoto emgwaqweni, kubalulekile ukuqonda ngokucacile ukuthi yiziphi izinhlobo ze-galvanization yomzimba wemoto ezibhekwa njengeziqinile kakhulu.
Ngokuthenga imodeli eyenziwe ngekhwalithi ephezulu yensimbi, ungakhohlwa ngezinkinga zokugqwala, emva kweminyaka engu-5-10 amaphutha ayoba amancane.
Izinhlobo ze-galvanization
Abanye abakhiqizi bezimoto zebhajethi baqinisekisa amakhasimende abo ukuthi ochwepheshe bahlobisa umzimba ngesisombululo sokuqala ngesikhathi sokudala, kodwa lokhu kuvikela akukwazi ukubizwa ngokuthi kungcono kakhulu.
Impendulo ngomzimba oyisithako
Imikhiqizo yakwamanye amazwe ezimisele ngesithombe senkampani yethula izimoto eziphumelele ukuhlolwa okuphelele, futhi isisekelo sensimbi simbozwe ngamagalvanized ashisayo, ama-galvanized noma abandayo. Lawa amabhrendi afana nalawa:
- IVolkswagen;
- IPorsche;
- I-Audi;
- Isihlalo;
- I-Skoda;
- UMercedes;
- I-Volvo;
- I-Opel;
- Ford;
- BMW;
Uma sikhuluma ngezimoto ze-VAZ, khona-ke wonke amakhophi akanalo izinga elifanayo lokuvikela ngokumelene nokugqwala. I-Zinc yengezwe kuphela kungqimba lwe-primer, kodwa kunzima ukubiza lolu hlobo lokwelashwa komzimba okuphelele. Izimoto eziphuma eChina nazo zingena kulesi sigaba, abanikazi beChery noma iGeely abakwazi ukushiya imoto emgwaqeni ngokuzethemba ngaphandle kokukhathazeka ngomphumela olimazayo wokugqwala.
Izindlela ze-galvanizing
Umsebenzi oyinhloko olandelwa izingcweti emafekthri, ziqala ukwenza noma yimuphi umzimba, ukwakha indawo ebushelelezi futhi elinganayo ekwazi ukumelana nokugoba noma ukuthuthumela. Phakathi kobuchwepheshe obuvamile bokusebenzisa isendlalelo sokuzivikela embonini yezimoto, okulandelayo kusetshenziswa:
- I-Thermal galvanization (iyashisa).
- I-Galvanic.
- Kuyabanda.
- Ngokusebenzisa i-zinc metal.
Ukuze ube nokuqonda okulungile kwezinhlobo ezingenhla zobuchwepheshe, kuyadingeka ukuhlaziya ngayinye ngokwehlukana.
Izici zokusebenza ezishisayo
Ochwepheshe babheka lolu hlobo lwe-galvanization yomzimba njengoluthembekile kakhulu futhi lusezingeni eliphezulu, ngoba umzimba wemoto ucwiliswa ngokuphelele esitsheni esikhethekile esine-zinc encibilikisiwe. Kuleli qophelo, izinga lokushisa loketshezi lifinyelela kuma-degree angu-500, insimbi ehlanzekile isabela futhi yakha i-coating ebusweni bomshini womshini.
Ubuchwepheshe bokusetshenziswa okushisayo kwenza kube nokwenzeka ukuthi ekugcineni uthole umzimba onogqinsi oluyisivikelo lwama-microns angu-15-20, noma ngabe kuvela imihuzuko, i-zinc izoqala u-oxidize, kodwa hhayi isisekelo sensimbi yemoto. Indlela isetshenziswa hhayi kuphela lapho udala imoto ye-premium, ezinye izinhlobo zebhajethi nazo zicutshungulwa kahle, sikhuluma nge-Renault Logan noma i-Ford Focus.
indlela ebandayo yama-galvanized
Le nqubo yokucubungula umzimba ibhekwa njengeshibhile, ngakho-ke isetshenziselwa ukukhiqizwa kwezimoto ezishibhile, kuhlanganise namamodeli esimanje e-Lada. I-algorithm yezenzo zamakhosi ihlotshaniswa nokusetshenziswa kwe-zinc powder ehlakazeke kakhulu kusetshenziswa i-sprayer ekhethekile, okuqukethwe kwensimbi esixazululweni kuyahlukahluka kusuka ku-90 kuya ku-93% yenani eliphelele loketshezi, kwesinye isikhathi abaphathi banquma ukusebenzisa kabili. ungqimba.
Le ndlela ivame ukukhethwa abakhiqizi baseShayina, baseKorea nabaseRussia ukuba bafake i-galvanize, amafekthri avame ukusebenzisa ukusetshenziswa okuyingxenye kwezingxube, kunokuba kube nezinhlangothi ezimbili, esimweni esinjalo, ukugqwala kungaqala ngaphakathi kwemoto, nakuba ingaphandle yemoto izobukeka iphelele. .
Izici zokufaka uthayela
Lapho kwenziwa inqubo, ukufafaza emzimbeni kusetshenziswa ugesi, ngoba lokhu, uhlaka lwemoto yesikhathi esizayo lufakwa esitsheni esikhethekile esine-electrolyte equkethe i-zinc. Indlela isiza izimboni ukuthi zonge kakhulu, ngoba ukusetshenziswa kuncishisiwe ngenxa yokusetshenziswa okufanayo kwesendlalelo. Ubukhulu bungahluka kusuka kuma-microns angu-5 kuye kwayi-15, okuvumela umenzi ukuthi anikeze iwaranti yeminyaka eyi-10 emkhiqizweni.
imoto kathayela
Ukucutshungulwa kohlobo lwe-galvanic akuhlukaniswa yizinkomba zokuthembeka okuphezulu, ngakho-ke, ochwepheshe bathuthukisa ikhwalithi yesisekelo sensimbi nge-primer.
Ukusetshenziswa kwensimbi ye-zinc
Le ndlela eyingqayizivele yokucubungula umzimba yasungulwa ochwepheshe baseKorea embonini yezimoto, esigabeni sokuqasha kwanqunywa ukusebenzisa insimbi ekhethekile ye-zinc, ehlanganisa izingqimba ezi-3:
- Insimbi.
- Ama-oxide aqukethe i-zinc.
- I-organic zinc compound.
Kunomehluko owodwa ophawulekayo ezindleleni zangaphambilini, hhayi umkhiqizo ophelile ohlanganisiwe, kodwa impahla ngokwayo, lapho uhlaka olusekelayo luzohlanganiswa khona.
Iyiphi i-galvanization engcono
Uhlobo ngalunye lwezingubo zokuzivikela lunamandla nobuthakathaka balo, kusukela kubo, unganquma ukuthi yiluphi uhlobo lokucubungula oluzophuma emgqeni wokuqala wokulinganisa.
Inqubo eshisayo ibonise imiphumela emihle kakhulu ekuvimbeleni ukugqwala, kodwa kunzima kakhulu ukufeza ungqimba olulinganayo, olubonakala emthunzini wemoto, uma ubhekisisa phezulu, ungabona amakristalu e-zinc.

Indlela ye-galvanic ivikela imininingwane ibe yimbi kakhulu, kodwa ukubukeka kuyacwebezela, ngisho, kuyilapho umenzi egcina izingxenye, ethula izimpahla kubathengi ngamanani ancintisanayo.
I-Cold galvanizing kanye nokusetshenziswa kwensimbi ye-zinc kuzosiza kuphela ukunciphisa izindleko nokunciphisa izindleko zomshini, kunzima ukukhuluma ngokuvikelwa okuphezulu kumswakama, kodwa ngokombono wezomnotho, lesi yisixazululo esihle kakhulu.
