1. Thaum ntau cov tuam ntxhab tsim cov khoom siv aluminium, txhawm rau txhawm rau txo tus nqi ntawm kev lag luam aluminium profiles, qhov muaj pes tsawg leeg ntawm cov txhuas ntshiab yog qhov txo, thiab ntau qhov chaw pov tseg aluminium lossis lwm cov impurities ntxiv. Qhov no ua rau lub tsev tsis zoo txaus ntshai.
2. Feem ntau qhov kev lag luam zoo aluminium yuav siv sijhawm ntau thaum nws tsim khoom. Cov neeg lag luam qis qis dua, lub sijhawm sib khi tsawg dua, thiab cov tshuaj lom neeg kuj tseem poob, yog li tus nqi ntawm cov khoom lag luam kuj raug txo, yog li cov khoom lag luam qis dua tsis zoo nyob rau hauv kev txhim kho corrosion.
3. Muaj ntau cov khoom lag luam ntawm cov khoom siv aluminium profile, ntau yam uas tsis tsim nyog, thiab cov tuab tsis txaus ntawm oxide zaj duab xis hauv cov txheej txheem tsim tau dhau los ua teeb meem feem ntau ntsib hauv cov khoom siv aluminium, vim tias qhov saum npoo ntawm txhuas profile yuav tsum yog Muaj cov yeeb yaj kiab oxide los tiv thaiv aluminium profiles los ntawm kev xeb, thiab cov uas xav txuag nqi yuav zoo li txiav cov fab ntawm qhov no.
