Why wenza i-aluminium alloy uthenge emuva unesikhunta namachashazi ngemuva kokugcinwa isikhathi esithile?

Le nkinga amakhasimende amaningi ahlangabezane nayo, futhi kulula kumakhasimende angenalwazi ukuthi ahlangabezane nezimo ezinjalo. Ukuze ugweme izinkinga ezinjalo, kubalulekile ukunaka amaphuzu amathathu alandelayo:

1. Indawo lapho izinto zibekwe khona kumele igweme ukuswakama. Amanye amakhasimende athenga izinto zokwakha azibeke ngaphansi kwamashede ensimbi, angase avuze imvula noma abe namaphansi aswakeme. Uma kushiywe isikhathi eside, amabala esikhunta nama-oxidation angase akheke.

2. Kumakhasimende ezinhlobo zokucubungula, ezifana nokwenza isikhunta, ukukhanda imishini, ukusika, njll., kufanele kuqashelwe ukuthi akhona yini ama-agent akhipha izinsalela, uketshezi lokusika, uketshezi lwe-saponification, njll. endaweni ebonakalayo. Lezi zinto ezonakalisayo kufanele zihlanzwe ngesikhathi. Ngemva kokuba impahla isicutshunguliwe, kufanele futhizigcinwe kahle. I-PolI-ishing wax, amabala kawoyela, njll. okusetshenziselwa ukucwecwa kufanele kuhlanzwe. Uma zingaphathwa kahle, kulula futhi ukubangela amabala aphuzi ebusweni bezinto ngesikhathi sokugcotshwa okulandelayo.

3. Ama-ejenti okuhlanza angalungile asetshenziswe kumkhiqizo ngokwawo angabangela ukugqwala kanye ne-oxidation yezinto ngokwazo.
