Feem ntau thaum ua thiab txiav cov khoom, nws yog ib qho tsim nyog yuav tau xaiv cov cuab yeej ua tau zoo, thiab qhov tseeb specification thiab qhov loj ntawm cov cuab yeej kuj tseem ceeb heev.
Tsis ntev los no, qee cov neeg tau nug seb cov hniav zoo li cas siv rau cov saw saws los txiav cov yas? Thaum koj tsis paub ib yam dab tsi, koj yuav tsum nrhiav ib lub chaw tsim khoom nrog cov thev naus laus zis hauv kev lag luam los sab laj thiab nkag siab. Tau kawg, Xiaobian tseem tuaj yeem pab koj daws qhov kev tsis ntseeg no.
Qhov tseeb, cov hniav zoo li ntawm cov txiav disc pom hniav hloov raws li cov khoom sib txawv. Cov ntaub ntawv xws li txiav aluminium, txiav ntoo, txiav hlau, txiav yas, thiab lwm yam sib haum rau cov hniav sib txawv, uas kuj yog cov kev xaiv tsim tom qab kev txhim kho txuas ntxiv hauv kev txiav.
