Txawm hais tias kev rov ua dua cov ntaub ntawv pov tseg yog ib qho kev lag luam uas txuas ntxiv mus rau niaj hnub no, tseem muaj kev nyuaj siab tshaj qhov kev lag luam. Siv cov khoom siv tooj liab rov qab, ib qho ntawm cov ceg ntawm kev lag luam, ua piv txwv, tseem muaj ntau yam teeb meem uas yuav tsum tau daws. Piv txwv li, ntau tus kws kho mob tsis paub yuav ua li cas kom paub qhov txawv ntawm cov khoom siv rov ua dua tshiab, ua rau txo qis kev siv cov khoom siv rov ua dua tshiab, thiab cov khoom zoo tsis ua raws li cov qauv tsim nyog. Uas tau hais tias, nws yog ib qho tseem ceeb uas yuav tau tham txog kev ua haujlwm ntawm cov khoom siv tooj liab rov ua dua tshiab.
Cov khoom ntawm lub cev thiab tshuaj lom neeg ntawm cov hlau yog qhov ruaj khov, ua rau nws tsis tshua muaj kev cuam tshuam rau lub cev thiab tshuaj lom neeg thiab ua kom nws cov purity. Yog li ntawd, kev faib tawm ntawm cov khoom siv tooj liab rov qab yuav tsum tau ua tib zoo tuav kom nws tuaj yeem ua tiav thiab siv rau hauv nruab nrab ntawm cov khoom siv tooj liab rov qab.
Tsis tas li ntawd, cov khoom siv tooj liab rov ua dua tshiab suav nrog ntau thaj chaw, xws li cov khoom siv tooj liab uas tau ua paug los ntawm ntau qhov chaw. Thiab cov ntsiab lus ntawm tooj liab hlau ntawm tooj liab seem sib txawv, yog li yuav muaj qhov sib txawv loj hauv kev ua tiav. Copper recycling yuav tsum xav txog tag nrho cov kev sib raug zoo ntawm cov khoom ntawm recycled tooj liab seem thiab kev ua hauj lwm. Kev ua haujlwm tsis zoo yuav ua rau muaj kev puas tsuaj rau cov seem tooj liab thiab ib puag ncig. Yog li ntawd, nyob rau hauv lub recycle ntawm tooj liab seem, nws yog ib qhov tsim nyog yuav tsum to taub qhov kev ua tau zoo ntawm cov tooj liab seem, tsuas yog ib qho kev nkag siab zoo dua, tuaj yeem ua tib zoo sib txawv rau hauv ntau pawg rau kev ua haujlwm.
Tsis zoo li cov txheej txheem rov ua dua tshiab rau cov khoom xws li cov khoom seem hlau thiab hlau, cov txheej txheem tooj liab cov khoom siv rov ua dua tshiab yog qhov yooj yim heev, thiab cov seem tooj liab raug txheeb xyuas nrog xoom cov pa phem thiab xoom hlau. Tib qho tooj liab tuaj yeem xa rov qab mus rau lub qhov cub kom hloov cov tshuaj tiv thaiv. Rau cov khoom siv tooj liab nrog rau qhov tsis zoo ntawm ib puag ncig, nws yuav tsum tau ua tiav siv cov khoom siv ntau dua. Txawm li cas los xij, txawm tias muaj cov txheej txheem yooj yim no, ntau tus neeg tseem muaj kev xav tsis zoo txog nws. Ib qho kev xav tsis zoo yog tias qee cov neeg ntseeg tias tooj liab yog cov hlau uas tsis muaj nyob hauv Suav teb tau ntev, thiab tsis muaj teeb meem ntawm overcapacity, thiab yog li ntawd tooj liab smelting ntau lawm yuav tsum tsis txhob txwv.
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
