Ngemuva kokuthi umshini wokwenza izipikili ukhiqize izinzipho eziqediwe, uma indlela yokugcina ingalungile, kulula ukwenza ukugqwala kwezipikili. Ungayenza kanjani izinzipho ezihlala isikhathi eside? Kunezindlela ezimbili zokugcina ezisetshenziswayo ezisetshenziswayo:
1. Ngemuva kokuthi izipikili zakhiwa, Phila it.
Imishini esetshenzisiwe yile: umshini wokupholisa kuqala wengeza i-sawdust ne-parafini, bese uthela izipikili. Umshini wokuphola wamukela umklamo wohlobo lwesigubhu. Kwakhiwa ungqimba oluvikelayo ebusweni, ukuze izinzipho azikhanyi nje kuphela kodwa futhi zimelana nokugcina. Izindleko zokupholizwa kwezipikili ziphansi, futhi kungenye yezindlela ezengeziwe ezomnotho nezisebenzayo.
2. Izipikili zinama-galvanized
Ngemuva kokuthi izipikili zenziwe futhi zakhiwe, kugayiwe. Ngemuva kokwelashwa okugayiwe, kuzokwakhiwa ungqimba oluvikelayo ebusweni bezipikili. Hhayi kuphela ikhwalithi yokubukeka kwezipikili ethuthukiswa, kepha futhi nokumelana nokushisa okuphezulu nokumelana nokugqwala kuyathuthukiswa. Kukhona izindlela zokuguqula izinsiza ze-electroplaning nezinzipho ezishisayo zezinzipho. Imishini idinga imishini yokwenza i-galvaning namakhemikhali ahlukahlukene. Izipikili zibekwe kwikhambi le-electroplating noma elixhumeke kakhulu ndawonye ngokuhlangana kwamanje. Noma uyihlanganise nobuso bezipikili ngezindlela ezifanele zomzimba nezamakhemikhali ukukhiqiza ukunamathela okuhle. Le nhlanganisela ingathuthukisa amandla esipikili, ngakho-ke ithandeka ngabakhiqizi abaningi. Imishini yezipikili ye-Galvaning ayikwazi ukusetshenziselwa kuphela izinzipho ze-galvaning, kepha futhi ingasetshenziselwa imikhiqizo ehlukahlukene yensimbi, njenge: izipikili zensimbi, izinzipho ezihlanganisiwe, kepha izindleko zokwelashwa zikhulu kakhulu, kepha izinzipho zokutshala zikhulu kunalezo zemishini yokwelashwa.
