Daim Ntawv Tooj Liab

Daim Duab Tshwj Xeeb ntawm Cov Ntawv Tooj Liab

Kev Piav Qhia Luv:

Cov Ntawv Tooj Liab raws li cov tooj liab electrolytic, zinc thiab cov ntsiab lus me me ua nws cov khoom siv raw, los ntawm kev ua los ntawm ingot, dov kub, dov txias, kho cua sov, ntxuav qhov chaw, txiav, ua tiav, thiab tom qab ntawd ntim khoom. Cov txheej txheem khoom siv ua haujlwm, plasticity, cov khoom siv kho tshuab, tiv thaiv corrosion, kev ua tau zoo thiab tin zoo.
