Txoj cai RoHS tswj 2002/95 / EC, kuj hu ua RoHS los yog Lead-Free, yog Kev Txwv Cov Cai Tswj Cov Khoom Uas Muaj Kev Tiv Thaiv uas qhia txog cov qib siab tshaj plaws hauv cov hluav taws xob thiab hluav taws xob. Tiam sis hauv kev tseeb RoHS txwv tsis pub muaj ntau yam tshuaj yeeb dej caw ntxiv. Nws kuj tseem txwv cov khoom hauv qab no:
Lead (Pb): <1000>
Mercury (Hg): <100>
Cadmium (Cd): <100>
Hexavalent Chromium: (Cr VI) <1000>
Polybrominated Biphenyls (PBB): <1000>
Polybrominated Diphenyl Ethers (PBDE): <1000>
RoHS cov lus qhia tsis tsuas yog txwv kev siv cov hlau lead hauv hluav taws xob thiab hluav taws xob, tab sis kuj muaj lwm yam tshuaj phem thiab.
Nrog rau qhov kev thov kom muaj kev tiv thaiv rau lub ntiaj teb no, kev siv lwm yam khoom muaj kuab raug txwv. Piv txwv, qhov teeb meem ntawm halogen pib sib txuas yog surfacing hauv kev lag luam hauv PCB vim tias muaj ntau heev ntawm cov tshuaj tiv thaiv halogen siv hauv PCB qhov kev lag luam.
Hologen, Greek thiab txhais tau tias "saline." Halogen muaj tsib hom tshuaj lom neeg xws li tshuaj fluorine, chlorine, bromine, iodine thiab astatine. Hauv kev lag luam hauv tuam txhab, bromine thiab chlorine yog qhov tseem ceeb ntawm kev txaus siab.
Bromine thiab chlorine compounds tau nthuav dav hauv hluav taws xob, khoom yas thiab PVC. Nws yog qhov tseeb hais tias halogens tsis ua mob rau tib neeg yog tsis muaj kev puas tsuaj rau ib puag ncig thaum lawv raug siv hluav taws xob thiab khoom siv. Txawm li ntawd los, lawv tau muaj qhov teeb meem txog kev nyab xeeb ntawm lawv txoj kev ua hauj lwm thaum lawv raug rho tawm.
Thaum hlawv cov khoom tsim kev puas tsuaj, nws yooj yim los tsim teeb meem tshuaj xws li cov tshuaj lom dioxin thiab hydrochloric acid (HCl). Los ntawm bioaccumulation, lawv ua teeb meem rau tib neeg kev noj qab haus huv thiab ib puag ncig ib txhis.
Cov ntawv cog lus hauv Circuit Court, daim npog qhov ncauj, cov yas moulds, cov khoom sib txuas thiab lwm cov khoom siv muaj hluav taws xob uas muaj halogenated, tshwj xeeb tshaj yog PBB thiab PBDE, uas yog cov tshuaj toxins. Yog vim li ntawd lub EU txoj cai RoHS txwv tsis pub siv PBB thiab PBDE.
Mus rau pem hauv ntej, electronics kev lag luam maj pom tau hais tias nws yog ib qho tsim nyog txwv tsis pub siv lwm lub tebchaw halogenated. Ua cov khoom halogen dawb tau tam sim no los ua qhov tseeb kev sib.
