GB HPb58-3 GB/T 26306 Chemical Element
GB HPb58-3 GB/T 26306 ntxiv rau carbon, hlau kuj muaj ib tug me me ntawm manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen ( N) thiab hydrogen (H). Cov ntsiab lus no tsis txhob txwm ntxiv los txhim kho qhov zoo ntawm cov hlau, tab sis yog coj los ntawm ore thiab smelting txheej txheem, yog li lawv hu ua impurity ntsiab. Cov impurities no muaj qee yam cuam tshuam rau cov khoom ntawm cov hlau. Txhawm rau kom ntseeg tau qhov zoo ntawm cov hlau, cov tshuaj muaj pes tsawg leeg ntawm txhua yam hlau yog nruj me ntsis raws li cov qauv kev qhia.
Cov ntsiab lus tseem ceeb yog raws li hauv qab no:
