Muaj ob hom kev sib tsoo tooj.
Ib qho yog lub khib nyiab tshiab, nws yog tooj ntawm cov khib nyiab. Lub tshuab cog hlau yog hu ua "home scrap" los yog "runaround". Cov khawb tooj tooj liab uas ua los ntawm cov ua piv ua tooj liab thiab cov khoom xa ncaj qha tuaj rau cov khoom cog yog hu ua "industrial waste copper", "spot scrap copper" ("prompt") los yog khib nyiab tshiab.
Qhov thib ob yog qhov qub tooj liab, nws yog siv tom qab cov khoom tso pov tseg, xws li kev tso tseg ntawm cov vaj tse qub thiab kev thauj mus los lossis kev puas tsuaj ntawm cov qub khib tooj liab. Cov ntaub ntawv tooj liab thiab tooj liab, seb puas yog nyob hauv lub xeev los yog hauv qhov khoom kawg, yog rov ua dua txhua theem ntawm cov khoom hauv lub neej. Nyob rau hauv dav dav, rau kev tsim rov qab ntawm kev pov hwm tooj liab nyob rau hauv lub tshiab tooj liab lees paub ntau tshaj ib nrab. Thiab tag nrho cov khib nyiab tooj tom qab rov ua dua txog li 1/3 rau daim ntawv ntawm cov tooj liab kom rov qab mus rau tom khw, ntxiv 2/3 kom tsis txhob ua kom tsis muaj tooj liab lossis tooj liab tooj hauv daim ntawv rov siv. Cov ntaub ntawv ncaj nraim ntawm cov khib nyiab tooj yog lub hauv paus ntawm kev sib cais nruj ntawm kev khov thiab nruj sorting. Cov ntaub ntawv qhia txog kev siv khib nyiab muaj cov txheej txheem simplified, cov cuab yeej yooj yim, kev ua haujlwm siab, kev siv zog tsawg, cov nqi tsawg, lub teeb paug thiab lwm yam khoom zoo. Daim ntawv thov kev siv nyiaj pov tseg, ntau npaum li cas los ntawm lub teb chaws tus qauv tooj liab. Hauv kev sib piv, txoj kev siv sib piv ntawm kev siv khib nyiab hauv Suav teb tsawg tsawg, qis tshaj 200,000 t tauj ib xyoo, tsuas yog 30% txog 40% ntawm tag nrho cov khib nyiab tooj liab rov qab, thiab cov khoom siv tooj dag ntawm cov tuam txhab hauv nroog, Txhawm txo kev lag luam efficiency, thiab kev siv zog, kev tiv thaiv ib puag ncig los ntawm teeb meem.
Tuam Tshoj txoj kev tuaj yeem txuag cov tooj liab tsuas yog los ntawm Teb Chaws Asmeskas, Nyiv, Lub Nroog, Tebchaws Mekas, uas yog Tebchaws Meskas tau muab teev tseg, thaum Tebchaws Asmeskas nyob rau kev tswj hwm kev pov tseg thiab kev cai nruj. Mus rau Tebchaws Meskas raws li cov txheej txheem raug muab coj los ua ke. American khib nyiab tooj yog cais raws li purity. Lub Teb Chaws Asmeskas siv cov khoom siv hlau ua dua tshiab thiab cov tooj liab thiab nws cov phom yog muab faib rau hauv 53 pawg.
Tebchaws Asmeskas feem ntau muaj ntau tshaj 99% Cu ntsiab lus ntawm tooj yog hu ua Tsis yog 1 daim tooj liab, Tsis yog 1 tooj coj tau ncaj qha mus siv thiab siv, tsis tas yuav ua ntxiv; cov ntsiab lus tooj liab ntawm qhov qis tshaj 94.5% tooj hu ua tooj liab, qhov khib nyiab Qhov no yuav tsum raug muab tshem tawm ua ntej nws siv los ua daim hlau tooj hlau. Lwm hom kev sib cais muaj xws li tooj dag, tooj dag thiab roj zas, tooj liab, tsheb kub dab, lub tooj liab tooj liab (liab tooj liab), thiab ntau hom kev kub ceev Cov nplais ncaj qha khoom siv thiab siv rau hauv daim ntawv tib qho chaw sib cais rau kev rov ua cov khoom siv tooj dag. Rau qhov chaw tsim tshuaj, nws lub ntsiab kom zoo dua yog qhov kev txo qhov nuj nqi ntawm cov khoom siv hlau. Khib tooj liab kuj siv los ua cov tshuaj tooj liab, tab sis nws tsis yooj yim kom tau cov ntaub ntawv ntau heev.
Tuam Tshoj tsis muaj qauv tooj, tab sis nrog rau kev ceev ntawm industrialization nyob rau hauv Suav teb kom ceev tau cov khoom rov qab los ntawm cov khib nyiab ntau hom non-ferrous hlau, kev lag luam thiab kev lag luam rov qab yog qhov kev coj noj coj ua hauv cheeb tsam muaj kev hloov tseem ceeb, tsis tsuas yog pov tseg tov nrog cov- ferrous metals varieties Tsim muaj kev hloov loj, thiab coob tus txawv teb chaws cov khib nyiab ntau hom hlau tsis zoo thiab txhua yam ntawm cov khoom pov tseg hauv lub teb chaws, rau peb cov khoom siv hlau tsis zoo muab kev nplua nuj ntawm raw cov ntaub ntawv, tab sis kuj rau cov khoom siv tshiab -Huab cov hlau tau ua dua tshiab Claim. Yog li ntawd, Tuam Tshoj kuj tseem nce siab txog kev tsim kho cov qauv hlau. China National Nonferrous Metals Kev Lag Luam Association Recycled Metal branch coj lub koom haum ntawm "tooj liab thiab tooj liab alloy khib nyiab seem kev lag luam thiab cov kev kho mob" tau muab tso rau hauv cov qauv kev txhim kho cov kev cai hauv lub teb chaws. Cov txheej txheem kev cais tshiab rau cov hlau tsis yog hlau yuav tsum yog raws li cov qauv hauv Teb Chaws Asmeskas cov qauv rau cov hlau tsis yog hlau thiab European classification ntawm cov qauv qhia ntawv, nrog rau Tuam Tshoj cov hluav taws xob txuas ntxiv uas tsis txuas cov hlau los txhim kho qhov teeb meem no, ua qhov zoo dua rau qhov kev siv ntawm kev lag luam thiab kev tswj hwm.
