Inferior aluminium profiles muaj plaub yam nram qab no:
1. Nyias oxide zaj duab xis. Lub teb chaws cov qauv qhia tias oxide zaj duab xis thickness ntawm architectural txhuas profiles yuav tsum tsis txhob tsawg tshaj li 10 μm (micrometers). Yog hais tias lub thickness tsis txaus, qhov saum npoo ntawm aluminium profile yog nquag xeb thiab corrosion. Thaum kuaj xyuas, qee qhov txhuas profile tsis muaj cov cim lag luam, chaw nyob hauv chaw tsim khoom, cov ntawv tso cai tsim khoom, lossis cov ntawv pov thawj ntawm kev sib raug zoo tau pom tias muaj oxide zaj duab xis tuab ntawm 2 txog 4 μm, thiab qee qhov txawm tias tsis muaj oxide zaj duab xis. Raws li cov kws tshaj lij kwv yees, rau txhua txhua 1 μm txo qis hauv oxide zaj duab xis thickness, tus nqi hluav taws xob ib tuj ntawm cov profile tuaj yeem raug txo los ntawm ntau dua 150 yuan. Piv txwv li, hnub ci txhuas profile tau siv cov xuab zeb blasting thiab oxidation kho ntawm qhov chaw, ua rau lawv tsis tshua muaj xeb thiab xeb, thiab oxide zaj duab xis tuab feem ntau yuav tsum siab tshaj 15 μm.
2. Tsis tsim nyog tshuaj muaj pes tsawg leeg. Aluminium profiles sib xyaw nrog ntau qhov tsis huv ntawm txhuas lossis cov khoom seem txhuas tuaj yeem txo cov nqi, tab sis qhov no yuav ua rau cov tshuaj tsis tsim nyog hauv cov vaj tse aluminium profiles, ua rau muaj kev phom sij loj rau kev nyab xeeb ntawm kev tsim kho.
3. Txo cov phab ntsa thickness ntawm profiles.
4. Inferior aluminium profiles ho txo lub sij hawm sealing, uas txo cov kev noj cov tshuaj reagents thiab txo tus nqi, tab sis kuj zoo heev txo cov corrosion kuj ntawm cov profiles.
