Cov khoom siv tseem ceeb sib txawv
PET (polyethylene terephthalate) yog technically ib tug tswv cuab ntawm tsev neeg plastics, tsis tau nws yog feem ntau sib tham sib cais-ntau npaum li cas lub smartphone yog ib hom xov tooj ntawm tes tab sis khav theeb muaj peev xwm zoo dua:
Lub raj mis yas txheem: feem ntau ua los ntawm PP lossis HDPE; lawv xav tias thicker thiab muaj matte tiav.
PET fwj: Muab iav -zoo li pob tshab; lawv yog lub teeb yuag tsis tau tawv, ua qhov txawv "snap-rov qab" suab thaum nyem.
Invisible ciam teb nyob rau hauv kev siv
Lub luag haujlwm ntawm ob lub thawv no ua si hauv lub neej txhua hnub yog qhov txawv ntawm kas fes thiab tshuaj yej:
Kev lag luam dej haus nyiam: 90% ntawm cov pa roj carbonated haus fwj yog ua los ntawm PET vim nws cov khoom siv roj zoo heev.
Kev saib xyuas tus kheej: Cov tshuaj zawv plaub hau feem ntau siv cov yas HDPE, uas muaj cov tshuaj tiv thaiv zoo tshaj.
Kub rhiab heev: PET lub raj mis deform yooj yim dua 70 degree, hos lwm lub raj mis yas tuaj yeem tiv taus qhov kub siab dua.
Environmental Performance
Nov yog qhov kev daws teeb meem rau koj qhov kev txiav txim siab ntawm qhov rov ua dua tshiab:
Recycling efficiency: PET fwj muaj tus nqi rov ua dua 60%; recycling ib tuj ntawm PET txo carbon emissions los ntawm peb tons.
Tus nqi degradation: Tus qauv yas fwj siv 450 xyoo los decompose lawm, thaum PET fwj siv kwv yees li 300 xyoo.
Cov ntawv siv rov ua dua: PET lub raj mis tuaj yeem hloov pauv mus rau hauv cov khoom siv hluavtaws hluavtaws, thaum lwm lub raj mis yas feem ntau tau ua tiav rau hauv cov yas pellets.
