Tooj Liab Strip
Kev Taw Qhia Txog Khoom
Cov Ntawv Tooj Liab raws li 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, 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 zoo tin. Nws tau siv dav hauv hluav taws xob, tsheb, kev sib txuas lus, kho vajtse, kho kom zoo nkauj thiab lwm yam lag luam
