Daim ntawv pov thawj RoHS (Kev txwv tsis pub muaj phom sij) yog cov txheej txheem kev cai tsim los ntawm European Union txhawm rau txwv kev siv qee yam khoom phom sij hauv kev tsim khoom siv hluav taws xob thiab khoom siv hluav taws xob. Lub hom phiaj ntawm RoHS yog txhawm rau txo kev puas tsuaj rau ib puag ncig thiab tib neeg kev noj qab haus huv los ntawm kev tsim khoom thiab pov tseg cov khoom no.
Cov khoom lag luam uas ua tau raws li RoHS cov cai muaj ntau qhov zoo dua cov uas tsis ua. Rau ib qho, lawv muaj kev nyab xeeb dua rau kev siv thiab tsis tshua muaj peev xwm tso cov co toxins rau hauv ib puag ncig. Lawv kuj yog feem ntau ntau dua eco-phooj ywg, raws li lawv tau ua nrog cov ntaub ntawv uas yooj yim rau rov siv dua thiab pov tseg kom raug.
Ntxiv nrog rau cov txiaj ntsig ib puag ncig, RoHS ntawv pov thawj tuaj yeem muab cov tuam txhab sib tw. Cov neeg siv khoom thiab cov lag luam tau paub ntau ntxiv txog qhov tseem ceeb ntawm eco-friendliness thiab kev nyab xeeb, thiab ntau tus tab tom nrhiav cov khoom uas ua tau raws li cov qauv no. Los ntawm kev tau txais daim ntawv pov thawj RoHS, cov tuam txhab lag luam tuaj yeem qhia lawv txoj kev cog lus rau cov txiaj ntsig no thiab tau txais lub koob npe nrov ua lub tuam txhab muaj lub luag haujlwm thiab ntseeg tau.
Yuav kom tau txais daim ntawv pov thawj RoHS, ib yam khoom yuav tsum raug kuaj thiab xyuas los ntawm qhov chaw kuaj xyuas thib peb uas tau lees paub. Cov khoom lag luam yuav tsum ua raws li cov qauv nruj rau qib ntawm cov hlau lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), thiab polybrominated diphenyl ethers (PBDEs). Thaum muaj ntawv pov thawj, cov khoom tuaj yeem tso saib RoHS lub logo ntawm nws cov khoom ntim thiab cov khoom lag luam.
Zuag qhia tag nrho, RoHS ntawv pov thawj yog ib txoj hauv kev tseem ceeb rau cov tuam txhab lag luam los qhia lawv txoj kev cog lus rau kev nyab xeeb, lub luag haujlwm ib puag ncig, thiab cov neeg siv khoom nyiam. Cov khoom lag luam uas ua tau raws li cov qauv no tuaj yeem pab cov tuam txhab muaj kev sib tw hauv kev lag luam uas hloov pauv tsis tu ncua thaum tseem ua rau lub ntiaj teb muaj kev noj qab haus huv.
