Yuav ua li cas xaiv qhov hloov qhov rooj?
Kev ntxhib los mos ntawm cov khoom siv:
Feem ntau, hloov cov twj yig siv. Thaum peb xaiv hloov ntsaws, peb yuav tsum xyuam xim rau cov khoom ntawm lub vaj huam sib luag.Tam sim no, cov khoom siv nyob rau hauv kev ua lag luam yog cov khoom siv hlau thiab cov khoom PC. Cov hlau alloy tau oxidation kuj zoo thiab stability, tab sis nws cov compressive rwb thaiv tsev kawm tsuas yog nyob ntawm nws cov tshuab.PC vaj huam sib luag, nws kub ua hauj, feem cuam kuj zoo dua. Feem ntau, cov kev lag luam zoo siab yog ua los ntawm cov khoom siv hauv PC, thiab lawv cov tawv nqaij zoo thiab textured.
Cov khoom lag luam:
Thaum peb yuav hloov cov chaw nyob, peb tuaj yeem saib seb puas muaj cov ntawv xov xwm dawb ntawm cov nyiaj xiab dawb thiab cov khoom siv nyiaj tooj sib txuas. Ib qhov yoojyim zoo yog du, ntshiab thiab tsis thaiv.
Khoom cim:
Thaum nriav cov chaw nres tsheb, koj tuaj yeem tshawb xyuas seb cov khoom puas muaj CE, IEC cov ntawv, thiab seb nws cov ntaub ntawv xov xwm puas tiav, xws li tus tswv lag luam chaw nyob, chaw nyob, thiab lwm yam.
