Ntawm cov khoom ntawm cov cim hlau, cov kev faib ua feem ntawm txhuas cov phiajcim rau ntau tshaj li 90% yog tias nws yooj yim kom tau txais cov yeeb yuj thiab ntau yam kev sib txuas ntawm Hniav txheej txheem .}} Cov yam ntxwv ntawm cov cim qhia tau hais txog cov paib ntawm txhuas yog li hauv qab no .
1. Lub ntom ntom ntawm hnyav thiab aluminium paib yuav tsis nce qhov hnyav ntawm cov cuab yeej thiab txuag nqi.
2. yooj yim rau cov txheej txheem aluminium muaj yooj yim rau stamp thiab yooj yim rau cov kev xav tau ntawm cov txheej txheem kos npe tshwj xeeb {}}
{{03. Zoo corrosion tsis zoo thiab ntom oxide zaj duab xis thiab dense oxide zaj duab xis tuaj yeem tsim nyob rau saum npoo ntawm txhuas thiab nws alloys .
4. huab cua zoo kuj cov txheej txheem txhuas oxide cov txheej txheem ntawm thaj chaw muaj kev nyab xeeb hauv thaj chaw muaj chaw thiab thaj chaw ntug dej hiav txwv.
{{0 {}} Tsis muaj cov sib nqus txhuas yog lub cev tsis sib nqus, thiab lub cim sib nqus yuav tsis ua rau muaj kev cuam tshuam sab nraud rau cov khoom .
6.} Cov khoom siv-nplua nuj Aluminium yog ntau, thiab cov khoom tawm ntawm cov hlau thib ob yog ob qho tib si hauv ntiaj teb no tso zis ....
