Izindaba

I-Aluminiumis isetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yesisindo sayo esingasindi, ukuqina, nokumelana nokugqwala okuhle kakhulu. Nokho, ayigonyiwe ngokuphelele ekugqwaleni. Kulesi sihloko, sizoxoxa ngezinhlobo zokugqwala eziwuthintayo, nezindlela zokuvimbela ukugqwala.

Kungani I-Aluminium Corrosion Ingalungile?

I-Aluminium ithandwa ezinhlelweni ezihlukene ngenxa yokuminyana kwayo okuphansi, iyenza ibe lula kunezinye izinsimbi njengensimbi. Yaziwa futhi ngezakhiwo zayo ezinhle kakhulu ze-thermal kanye ne-electrical conductivity. Kodwa-ke, iyakwazi ukuthonywa yizinhlobo ezahlukene zokugqwala, okuhlanganisa ukugqwala kwe-pitting, i-galvanic, kanye ne-inter-granular corrosion. Ukugqwala kwe-pitting kwenzeka lapho imigodi emincane kwakheka endaweni yensimbi ngenxa yokuchayeka ezindaweni ezinolaka. Ukugqwala kwe-galvanic kwenzeka lapho i-aluminium ihlangana nezinsimbi ezingafani phambi kwe-electrolyte, idala iseli lokugqwala. I-Inter-granular corrosion ithinta ama-alloys e-aluminium, yenza izinto zibe buthaka eduze kwemingcele yokusanhlamvu.

Amathiphu okuthi ungakugwema kanjani ukugqwala kwemigodi

Ukuze uvimbele ukugqwala kwe-aluminium, izimbotshana zokuvikela zisebenza kahle kakhulu.I-anodizing, imidwebo, kanye ne-powder coatingukunikeza umgoqo phakathi kwensimbi nendawo yayo egqwalayo, ukuvimbela umswakama nezinye izinto ezigqwalayo ukuba zifinyelele phezulu. Ukuhlanza njalo ngensipho ethambile namanzi kungasusa ukungcola okunqwabelene, kugweme ukugqwala ukushesha. Amakhemikhali anokhahlo kanye nezihlanzi ezilumayo kufanele zigwenywe ngoba zingalimaza ungqimba oluvikelayo.

Ukuvikela i-aluminium ekuxhumaneni okuqondile nezinsimbi ezingafani kunciphisa ubungozi bokugqwala kwe-galvanic. Izinto zokuvikela ezifana nepulasitiki noma i-rubber gaskets zingasetshenziswa ukuvimbela ukuthintana okuqondile phakathi kwe-aluminium nezinye izinsimbi. Ukwengeza, ukulawula ukuchayeka ezindaweni ezonakalisayo kubalulekile. Ukusebenzisa izinyathelo ezifanele zokungenisa umoya kanye nokulawula umswakama kunganciphisa amazinga omswakama kanye nokuba khona kwamakhemikhali noma amagesi agqwalayo.

Sengiphetha, nakuba i-aluminium inezinzuzo eziningi, iyakwazi ukugqwala. I-Pitting, i-galvanic, kanye ne-inter-granular corrosion yizinhlobo ezivamile ezithinta i-aluminium. Ukusebenzisa izinto ezivikelayo, ukugcina ukuhlanzeka, ukugwema ukuthintana nezinsimbi ezingafani, nokulawula ukuchayeka ezindaweni ezigqwalile kuyizindlela eziphumelelayo zokuvimbela. Ngokusebenzisa lezi zinyathelo, isikhathi sokuphila nokusebenza kwe-aluminium kungakhuliswa, kuqinisekiswe ukusetshenziswa kwayo okuqhubekayo ezinhlelweni ezihlukahlukene.

Uma uneminye imibuzo mayelana nokuvimbela ukugqwala kwe-aluminium, zizwe ukhululekile ukwenza kanjaloXhumana nathiukufunda okwengeziwe. Ukuvimbela kuhlale kuyisu elingcono kunokubhekana nokugqwala uma sekuqalile.
