Dab tsi ua rau tsev neeg ua cov ntawv ci muab piv rau lwm cov khoom noj ntim khoom noj?
Tsev neeg cov ntawv ci yog 100% siv tau vim tias nws tuaj yeem tau melted cia thiab rov ua kom zoo, tsis zoo li cov roj hmab thaum lub sij hawm rov ua dua tshiab. Tus txheej txheem rov ua dua tshiab rau txhuas kom muaj 5% ntawm lub zog uas xav tau rau thawj kev tsim khoom, ua rau nws muaj kev ruaj khov. Feem ntau cov chaw ua haujlwm txais huv txhuas ntawv ua ke nrog cov kaus poom, txawm hais tias qee tus yuav tsum tau balled mus tiv thaiv cov teeb meem sorting. Tsis zoo li cov ntim sib xyaw-khoom ntim (xws li chip hnab), ntshiab txhuas ntawv siv tsis tas yuav sib cais los ntawm lwm yam. Siv cov ntawv tshaj tawm siv cov khoom lag luam pov tseg los ntawm kev khaws cov khoom muaj nuj nqis hauv kev ncig.
Yuav ua li cas cov neeg siv khoom yuav tau siv Aluminium ntawv ci rau kev rov ua dua tshiab?
Cov Khoom Noj Khoom Noj yuav tsum tau muab pov tseg kom tshem tawm los ntawm kev so lossis yaug cov ntawv ci, xws li cov paug tsis muaj peev xwm cuam tshuam rau cov txheej txheem rov ua dua tshiab. Cov ntawv me me yuav tsum tau sau thiab compressed rau hauv ib lub pob (tsawg kawg 5cm hla) kom ntseeg tau tias lawv tsis ploj thaum sorting. Zam kev sib xyaw ua cov ntawv ci nrog cov ntaub ntawv yas zoo li yogurt hau yogurt hau lossis cov thawv kua txiv uas zoo sib xws tab sis tsis siv sij hawm. Tshem tawm tej yam uas tsis yog Aluminium Cheebtsam zoo li ntawv sau lossis txheej txheej yas los ntawm cov ntawv ci. Kuaj cov lus qhia ua haujlwm hauv zos, raws li qee lub nroog kom tau muab ntawv nyiaj muab tso rau hauv cov khoom sib sau tshwj xeeb.
Dab tsi feem pua ntawm tsev neeg Aluminium ntawv nyiaj tau ua tau txais cov khoom siv tam sim no?
Kev lag luam kwv yees hais tias tsuas yog hais txog 30-50% ntawm cov khoom siv nyiaj txiag hauv tsev vim yog paug thiab pov tseg tsis raug. Cov teb chaws Europe coj nrog 50-70% rov qab cov nqi hauv cov cheeb tsam uas muaj cov khoom siv hluav taws xob. Hauv Asmeskas, tus nqi rov qab ua dua tshiab rau {2}}}}}}}} partly vim tias ntau tus neeg siv khoom tsis paub huv ntawv. Kev tsim cov lag luam feem ntau tsis muaj cov tshuab sau, ua rau cov ntawv luam ntau tshaj plaws hauv cov av qias neeg. Nce cov kev kawm pej xeem tuaj yeem muaj peev xwm muab ob npaug rau kev rov ua dua tshiab nyob rau hauv kaum xyoo.
Puas muaj kev txwv rau pes tsawg lub sij hawm aluminium ntawv ci tuaj yeem rov ua dua tshiab?
Tsis zoo li yas, txhuas tsis muaj theoretical recycling txwv vim tias cov qauv atomic tseem tsis tau ua rau melting thaum lub sijhawm yaj. Impurities los ntawm inks lossis cov zaub mov seem yuav xav tau kev noj haus nrog ntshiab aluminium tom qab ntau pua mus ncig, tab sis qhov no tsis txo qis. Tam sim no sorting technologies tam sim no tuaj yeem tshem tawm 99% ntawm cov paug tsis huv thaum ub. Qee tus hwm hwm cov khoom lag luam muaj ntau dua 80% tom qab cov neeg siv khoom siv. Cov kev txwv tseem ceeb tsis yog cov khoom siv tsis haum tab sis sau nyiaj txiag thiab cov neeg siv kev koom tes.
Kev nrhav kev nrhav tau txhim kho lub rov qab los ntawm txhuas ntawv ci?
Cov txheej txheem dej tshiab hloov cov khaub noom yas laminates thaum tswj cov zaub mov muaj kev nyab xeeb thiab ua kev sib cais yooj yim dua. Laser etching tshem tawm cov kua paug tsis huv los ntawm kev hloov cov ntawv sau nrog cov cim cim kev cim. Qee hom npe tam sim no ntxiv me me ntaus cim rau kev pab tshuab sorting sorting tshuab txheeb xyuas cov ntawv kom meej. Cov tuam txhab tsim khoom yog tsim cov ntawv tsim tawm tsis tau muaj zog dua cov ntawv ci (hauv 6 microns) uas siv cov khoom tsawg yam tsis muaj kev ua tau zoo. Cov kev tshaj tawm hauv cov neeg ntse thauj nrog QR cov lis dej num uas qhia txog cov neeg siv khoom txog kev ua kom zoo dua.
