Lub raj mis kis las yog txhuas alloy, puas muaj kev ua kom raug mob

Aluminium muaj me ntsis solubility hauv dej, thiab zaj duab xis oxide ntau yog tsim rau saum npoo ntawm aluminium alloy. Nws lub ntsiab feem yog tri-alumina, uas kuj yog soluble heev, tab sis nws tuaj yeem yaj hauv cov kua qaub muaj zog thiab txhuas. Kev daws teeb meem hauv alkali muaj zog, yog li yuav tsum sim kom tsis txhob muaj dej acid acid, xws li txiv qaub, kua qaub, tab sis vim tias oxide zaj duab xis yog qhov ntom, qhov cuam tshuam ntawm lub zog qeeb heev, thiab cov xaim yog txawv ntawm cov hlau ntshiab, qhov kev tiv thaiv corrosion yog muaj zog, yog li Cov hmoov txhuas yaj hauv cov dej haus yuav tsum yog me me thiab tsis muaj kev cuam tshuam pom tseeb rau tib neeg lub cev. Tsis tas li ntawd, cov khoom tseem ceeb ntawm zib ntab yog qee polysaccharides, zib ntab dej yog nruab nrab, tsis muaj teeb meem
