EU qhia RoHS - yog dab tsi?

Tam sim no, lub ntiaj teb no lub zej lub zos ntau thiab ntau xim rau tej teeb meem. Los ntawm leaps thiab ciam teb yog txoj kev loj hlob ntawm cov tshiab technologies, tsuas, hauv nyob hauv qhov chaw ntawm deserts thiab roob. Txawm li cas los, nrog rau qhov zoo yam ncaj qha mus txuas rov qab mus rau lawv cov kev tsis zoo: ib puag ncig kev ua qias tuaj, extinction muaj thiab fauna, deforestation, ozone havzoov tas, kev havzoov ntawm uas tsis yog-txuas ntxiv dua mus pab , thiab hais txog. Tag nrho tej yam muaj ib tug tsis zoo feem on tib neeg lub neej thiab noj qab haus huv, thiab nws xeeb leej xeeb ntxwv. Nyob rau hauv thiaj li yuav tiv thaiv cov seem tej yam ntuj tso wealth, raws li zoo raws li pre-empt lub rov tshwm sim ntawm ntau hom ntawm neeg tuag taus thiab loj cov kab mob txuam nrog niaj hnub tsim, lub teb chaws yuav siv bans nyob rau kev siv tej teeb meem rau cov neeg ciaj lub cev. Ib tug ntawm cov txheej txheem yog qhov kev txiav txim ntawm RoHS. Yuav ua li cas yog nws thiab yog dab tsi hom ntawm kev ua si yog siv - piav nyob rau hauv no tsab xov xwm.

Txwv ntawm Tej tshuaj

Nyob rau hauv Lub Xya hli ntuj 2006, nyob rau lub tom ntej no lub rooj sib tham ntawm cov European Union tug States lub qhia tau kos npe, raws li uas kom txwv rau kev siv ntawm tej yam nyob rau hauv txoj kev loj hlob ntawm hluav taws xob los yog hluav taws xob khoom. Qhov kev txiav txim yog hu ua RoHS. Yuav ua li cas qhov no txhais tau decipher? Txwv ntawm Tej tshuaj - qhov no yog tag nrho cov npe ntawm cov tswj. Qhov no kab lus yog txhais li "txwv ntawm Tej tshuaj." Nws yuav tsum tau muab sau tseg hais tias qhov no qhia tsis yog thawj zaug ntawm nws hom. Nws cia li sau tau ib puas-loj hlob tus naj npawb ntawm cov ntaub ntawv regulating tus tshiab yees uas yog siv tau rau cov ib puag ncig. Tus txiav txim, uas cia siab rau nyob rau hauv lub sib ntaus rau lub purity ntawm cov ntiaj chaw, tau lub European Union lub WEEE qhia. Sia tsiaj sawv ob Khib los ntawm Hluav taws xob thiab Electronic Khoom, uas txhais tau tias "Khib Hluav taws xob thiab Electronic khoom." Tsis ntev nws ntxiv daim ntawv RoHS. Hais tias qhov kev txiav txim yuav ua nrov thiab nrhiav kev pab txhawb nqa, tsis tsuas nyob rau hauv cov teb chaws Europe tab sis kuj deb tshaj nws cov ciam teb, tsis ntseeg li. Txawm li cas los, thaum lub caij, ua tsaug rau cov kev ntsuas coj nyob rau hauv lub tshav pob ntawm kev cai lij choj nyob ib ncig ntawm lub ntiaj teb no yog sib ntaus sib tua rau lub ecological tshuav nyiaj li cas thiab cov kev siv ntawm ntsuab technologies.

Ntaus ntawm tej tshuaj: rau "tsis muaj"

RoHS ntawv constrains siv rau tshuaj piav hauv qab no.

  1. Lead. Nyob rau hauv lub tshuaj periodic system, qhov no caij yog raug xa mus rau raws li Pb. Lead yog ib yam ntawm cov feem ntau txaus ntshai tshuaj, tug los rau muaj sia nyob. Qhov siab tshaj plaws concentration ntawm no cov ntaub ntawv thiab ntawm lub tebchaw nrog nws koom tes nyob rau hauv cov khoom yuav tsum tsis txhob ntau tshaj 0.1% ntawm tag nrho cov.
  2. Cadmium. Nws Latin los - Cd. Qhov feem pua rau cov ntsiab lus ntawm no lub caij yuav tsum tsis txhob ntau tshaj 0.01 hnyav feem ntawm tag nrho cov.
  3. Mercury. Qhov no yog ib tug txaus ntshai tshuaj thiab hais txog co nyob rau hauv lub periodic lub rooj yog raug xa mus rau raws li Hg. Maximum concentration ntawm no cov ntaub ntawv uas muaj peev xwm tsis muaj ntau tshaj li 0.1%.
  4. Zoo li cov uas yuav tsum tau yog mercury thiab hexavalent chromium (Kr + 6). Los ntawm cov xwm, cov tshuaj yeeb dej caw yog ib tug muaj zog oxidizer thiab mas lom cov ntaub ntawv.
  5. Tsis tas li ntawd, ib tug heev tshuaj lom compound nrog ib tug bromine (Br), raws li polybrominated biphenyls.
  6. Polybrominated diphenyl ethers. Feem ntau cov ntaub ntawv (5 thiab 6) siv nyob rau hauv hluav taws xob yees xws ntsiab tsis raug ceev tiv cav tseb. Qhov siab tshaj plaws concentration ntawm txhua tus ntawm cov tshuaj yuav tsum tsis txhob ntau tshaj 0.1% ntawm tag nrho cov.

Lub siab xav kom lub ntiaj teb

Ntawm cov hoob kawm, kev txwv ntawm kev siv ntawm cov saum toj no yam nrhiav tej hom phiaj. Thaum uas siv cov ntau benign thiab ntshiab tshuaj ua manufacturers xav lub siab tshaj plaws:

  • txo cov pa phem thiab lub tom ntej kev puas tsuaj ntawm lub ntiaj teb lom week;
  • negate tau lom ntawm cov saum toj no yam, thiab nws ua raws ntawm no thiab cov kev tiv thaiv ntawm kev noj qab nyob cov teeb meem ntawm cov neeg uas siv los yog ua hauj lwm nrog tsis zoo electronics los yog hluav taws xob khoom siv.

Rau electronics manufacturers

Nws txaus siab yog cuam tshuam los ntawm lub saws ntawv RoHS? Hais tias qhov no txiav txim tau kev txhawb los ntawm, thiab sab nraum teb chaws Europe - yog tsis xav tsis thoob. Nyob rau hauv qhov tseeb, muaj ntau lub teb chaws yog exporters ntawm cov khoom rau ib ncig ntawm lub Union. Yog li ntawd, nyob rau hauv thiaj li yuav tau kev pom zoo rau cov nyob sab Europe lag luam, hluav taws xob los yog hluav taws xob khoom uas yuav tsum tau raws li ncua tej uas yuav tsum tau. Yog hais tias cov khoom yog kev ruaj ntseg kiag, nws yog muab tso rau ntawm daim ntawv lo RoHS raws txoj cai, uas txhais tau tias "muaj raws li qhov uas yuav tsum tau ntawm cov RoHS tswj."

Txhua yam uas nyob ib ncig peb

Yog li, raws li cov tau piav ntawv, qhov hluav taws xob los yog hluav taws xob khoom, uas peb siv nyob rau hauv lub neej txhua hnub, yuav tsum ua raws li cov ecological kev ruaj ntseg. Yog li ntawd, RoHS ntsiav tshuaj yuav tsum tsis txhob muaj hmoov txhuas adhesions thiab lwm yam teeb meem hais. Qhov no kuj siv rau ib tug ntau yam ntawm cov khoom siv thiab cov khoom siv, teeb pom kev zoo systems, cov khoom ua si, tsis siv neeg fixtures, hluav taws xob thiab hluav taws xob seev thiab thiaj li nyob. Tam sim no, manufacturers ntawm hloov rau luam yeeb thiab haus luam yeeb kuj hmoog rau daim ntawv no. Feem ntau lo lus "electronic luam yeeb RoHS» yuav muaj nyob rau hauv khw muag khoom noj. Qhov no qeb ntawm cov khoom, tab sis yog tsis yog kiag li txawm (vim lub xub ntiag ntawm nicotine), tab sis hais tias cov tsis muaj cov ntaub ntawv siv los tsim cov khoom, kev piam sij thiab noxious tshuaj.
