Kev ua phooj ywg ib puag ncig ntawm aluminium alloy laj kab feem ntau yog tswj los ntawm peb yam: raw khoom, txheej txheem tsim khoom, thiab kawg- siv rov ua dua. Cov hauv qab no yog cov cai tshwj xeeb ntawm cov qauv loj thoob ntiaj teb:
1.Txoj kev txwv tsis pub muaj kev phom sij hauv cov khoom siv
EU RoHS Cov Lus Qhia tau teev tseg tias cov ntsiab lus siab tshaj plaws ntawm rau cov khoom phom sij hauv cov khoom siv txhuas, suav nrog cov hlau lead (Pb), cadmium (Cd), thiab mercury (Hg), yog 0.1% (1000 ppm), thiab hexavalent chromium (Cr{2}}) yog 0.01% (100 ppm). Tau qhov twg los: EU Directive 2011/65/EU.
Tuam Tshoj tus GB/T 5237-2017 xav kom cov ntsiab lus ntawm txhuas thiab cadmium nyob rau hauv txhuas profiles yuav tsum tsawg tshaj li los yog sib npaug zos rau 0.1% raws li, thiab lwm yam hnyav hlau yuav tsum tau ua raws li "Comprehensive Plan for the Prevention and Control of Heavy Metal Pollution".
2.Environmental Friendliness ntawm Surface Treatment txheej txheem
Cov hmoov txheej yuav tsum ua raws li EU QUALICOAT Chav Kawm 1 tus qauv, nrog VOC (volatile organic compound) emissions Tsawg dua lossis sib npaug li 50g / m².
Hauv cov txheej txheem anodizing, qhov concentration ntawm chromium ions hauv cov dej khib nyiab yuav tsum qis dua 0.5 mg / L (Tuam Tshoj Integrated Wastewater Discharge Standard GB 8978-1996).
3.Prioritize kev siv cov khoom siv rov ua dua tshiab: Lub zog siv ntawm cov khoom siv txhuas rov ua dua tshiab tsuas yog 5% ntawm cov ntaub ntawv nkauj xwb, thiab cov pa roj carbon emissions raug txo los ntawm 95% (cov ntaub ntawv los ntawm International Aluminium Institute).
4.Design ib lub qauv qauv: yooj yim disassembly thiab recycling, nce cov khoom siv rov ua dua mus rau ntau dua 90%.
