Kev paub me me ntawm qhov chaw nres tsheb-qhov sib txawv ntawm cov hlau lead lossis cov hlau tsis muaj hlau lead
1. Qhov sib txawv ntawm cov hlau lead thiab cov hlau tsis muaj hlau lead tsuas yog qhov sib txawv ntawm cov ntsiab lus.
2. Cov hlau lead uas muaj cov hlau lead yuav tsum tau muab ntxiv nrog cov hlau lead. Qhov zoo tshaj plaws paub qhov sib piv yog tin-lead solder hlau (tus qauv hauv tebchaws: tin cov ntsiab lus 63 feem pua, cov ntsiab lus txhuas 37 feem pua).
3. Cov hlau tsis muaj hlau lead kuj tseem muaj cov hlau lead me me heev, thiab tam sim no tsis muaj cov khoom siv hlau ntshiab kiag li. Feem ntau cov hlau tsis muaj hlau lead yog hu ua lead-free solder wire. Lead-free tsis txhais hais tias nws tsis muaj txhuas txhua. Lead-free txhais tau hais tias cov ntsiab lus ntawm cov hlau lead yog qhov tsawg, uas tuaj yeem suav hais tias tsis muaj txhuas. EU txhais cov qauv tsis muaj txhuas raws li: 1000PPm. Xav txog qhov muaj peev xwm ua kom muaj kuab paug ntxiv hauv kev vuam thiab tom qab ua tiav, txhawm rau kom ntseeg tau tias cov neeg siv khoom tiav cov khoom ua tau raws li EU tus qauv, cov ntsiab lus txhuas ntawm cov hlau hlau dav dav yuav qis dua li tus qauv no.
4. Ob qho tag nrho cov hlau lead thiab cov hlau tsis muaj hlau lead yuav corrode qhov kawg ntawm cov hlau soldering, vim tias qhov kub tsis muaj cov hlau lead yog siab dua li cov hlau lead hlau, thiab cov hlau alloy muaj qhov sib txawv, cov hlau tsis muaj hlau lead yog Feem ntau yuav corrode cov hlau soldering, vim yog cov hlau lead-dawb thiab corrosiveness, nws raug nquahu kom siv cov hlau lead-dawb tshwj xeeb hluav taws xob soldering hlau thaum soldering hlau tsis muaj hlau lead.
