Why Ngabe i-aluminium alloy Ukuthengiwe emuva kube nokubumba kanye namabala ngemuva kokugcinwa isikhathi esithile?

Le nkinga ihlanganiswe namakhasimende amaningi, futhi kulula kumakhasimende angenalwazi ahlangabezana nalezo zimo. Ukugwema izinkinga ezinjalo, kudingeka kuphela ukunaka amaphuzu amathathu alandelayo:

1. Indawo lapho kubekwa khona izinto zokwakha kufanele zigweme ukudedela. Amanye amakhasimende athenga izinto zokwakha futhi azibeke ngaphansi kwezindawo ezilula ze-iron, ezingavuza imvula noma zibe nezitezi ezimangele. Uma kushiywe isikhathi eside, amabala wokubumba kanye nama-oxidation angakha.

2. Kumakhasimende ezinhlobo zokulungisa, njengokwenza isikhunta, imishini, ukusika, ukunakekelwa ukuthi ngabe kunendawo yokukhishwa, ukusika uketshezi, uketshezi lwe-saponication, njll. Esikhathini esibonakalayo. Lezi zinto ezilimazayo kufanele zihlanzwe ngendlela esifike ngesikhathi. Ngemuva kokucutshungulwa, kufanele futhizigcinwe kahle. UhloboUkugeza i-wax, amabala kawoyela, njll. Isetshenziselwa ukucwaswa kufanele kuhlanzwe. Uma bengaphathwa kahle, kulula futhi ukudala amabala aphuzi ebusweni bezinto ezilandelwayo.

3. Ama-ejenti wokuhlanza angafanele asetshenziswe kumkhiqizo ngokwawo angabangela nokugqwala kanye no-oxidation of the wal uqobo.
