Kufanele kubhekwe ekuqothulweni kwesiliva ezingxenyeni zethusi zemishini.

Ukwakheka kwensimbi yezingxenye zethusi kukhululeke ukwedlula lokho ithusi eligoqiwe, futhi ukubukeka kwalo kunzima futhi kubumba, ngaphezu kwalokho, ngaphezu kwengxenye yezindawo zethusi kuvame ukushiywa nengxenye yesihlabathi sokubumba, i-paraffin wax kanye nezinto ezibucayi. Uma ukuhlanza kungahlanzekile, kuvame ukubangelwa yipuleti eliyingxenye, ngakho-ke, ukuhlanzwa komhlaba kwezethusi machina nokuqinisa izinyathelo ezifanelekileyo kuyisihluthulelo sokuxazulula ikhwalithi yeplanethi yesiliva.

Izingxenye ze-General Copper zingafakwa emnyani kanjena:

I-Alkaline Chemical Decing → Ukugeza amanzi ashisayo → Ukugeza amanzi okushisayo → Ukugeza amanzi → Susa le filimu → Ukugeza amanzi → ukucwilisa

Ngenxa yesakhiwo sensimbi esezingeni eliphakeme ne-porous ekuguqukeni kwemishini yezingxenye zethusi, izidingo zenqubo kumele zilawulwe ngokuqinile:

(1) Ukuhlanza kwenqubo ngayinye kuzoba ngcono, futhi isixazululo esisele kuma-pores siyovinjelwa ekuthinteni inqubo elandelayo;

(2) Indawo yangempela engaphezulu yezingxenye zethusi inkulu kakhulu kunendawo ebaliwe. Lapho i-electroplating, umthelela ubuningi bamanje bungaphezulu kwamahlandla ama-3 aphezulu kunalezo zezingxenye ezijwayelekile, futhi isikhathi sokuthambisa kwangaphambilini isikhathi eside kunalokho kwezitho ezijwayelekile;
