Yog cov hmoov txhuas tsis muaj muag nyob hauv soldering iRons lom?
Cov khoom siv siv rau soldering nrog cov hluav taws xob tshuab hlau yog cov hlau, uas, txawm hais tias tsuas yog muaj cov hlau, kuj muaj lwm cov hlau. Nws yog feem ntau muab faib ua cov hmoov txhuas thiab txhuas dawb (piv txwv li ib puag ncig cov phooj ywg) hom. Nrog rau kev qhia txog ntawm EU ROHS qauv, ntau thiab ntau pcb stoldering cov khoom lag luam yog xaiv cov phooj ywg-tsis muaj ib puag ncig. Cov tshuaj txhuas txhuas kuj maj mam hloov, thiab tsis muaj ib puag ncig phooj ywg tsis tuaj yeem raug xa tawm. Leading dawb solder muab tshuaj txhuam, txhuas dawb sold hlau, thiab ua cov solder dawb sawb kab txaij tam sim no yog cov khoom tseem ceeb ntawm kev ua lag luam.
Cias muab tso, cov siv uas nquag siv tau muaj qhov sib tw tsawg, uas muaj txog 60% lead thiab 40% Tin, yog li cov cam, yog li cov ham yog lom. Feem ntau ntawm cov cam ntawm kev ua lag luam yog hollow thiab muaj Rosin, yog li cov roj koj tau xa mus rau tej zaum yog evaporated thaum lub rosin nyob rau hauv cov cam melts thaum solding.
Cov roj tau emitted los ntawm volatilization ntawm Rosin kuj tseem me ntsis lom, thiab cov roj no yog qhov tsis kaj siab heev. Lub ntsiab ntawm kev phom sij tseem ceeb ntawm cov soldering yog hmoov txhuas yog txhuas cov pa luam yeeb, cov hmoov txhuas muaj qee qhov kev coj ua.
Cov pa luam yeeb taug txhuas muaj qhov txwv tsis pub tshaj plaws hauv GBZ 2-2002}} thiab yog cov tshuaj lom neeg tshwj xeeb, xav tau kev tiv thaiv tshwj xeeb. Vim kev puas tsuaj los ntawm kev siv vuam rau tib neeg kev noj qab haus huv thiab ib puag ncig tau raug tswj hwm los ntawm kev cai lij choj tsis pub. Muaj cov kev coj ua kom pom tseeb hauv ISO14000 tus qauv rau kev kho thiab kev tiv thaiv ntawm cov kab mob muaj zog tsim hauv cov txheej txheem ntau lawm.
Tin muaj cov hmoov txhuas, thiab yav dhau los, soldering tau cais raws li kev ua haujlwm hlau vim yog cov txhuas nyob hauv cov kab mob ua haujlwm hauv tebchaws); Tam sim no, feem ntau ntawm peb cov kev lag luam siv cov hlau txhuas dawb cov hlau, uas yog tsuas yog siv cov tin. Kev tiv thaiv kab mob thiab tswj chaw ntsuam xyuas Tin Dioxide; Tsis suav nrog hauv National Loconenational CATORGOG.
Cov tshuaj dawb ua tsis tshaj tus qauv rau cov tshuaj lom txhuas, tab sis muaj lwm yam kev phom sij (Rosin zoo li cov khoom siv), uas tuaj yeem suav hais tias yog ib kis. Cov neeg ua haujlwm feem ntau txheeb xyuas qhov txheeb xyuas tus kheej yog thiab hom twg uas lawv tuaj yeem muab cov tswv yim rau lub Hoobkas sib koom ua ke).
Yog hais tias tus tin siv yog hmoov txhuas, nws yog qhov ua phem rau lub cev. Sij hawm dhau mus, lawv khaws cia hauv lub cev thiab ua rau muaj kev tiv thaiv kev puas tsuaj loj rau cov leeg ntshav.
Leading dawb tshuab hlau yog ib puag ncig ua phooj ywg, tab sis nws kuj yog kev ua mob rau tib neeg lub cev. Cov ntsiab lus txhuas tsawg ntawm cov txhuas dawb hlau tsis txhais tau tias nws tsis muaj cov hmoov txhuas. Piv nrog cov hmoov txhuas muaj cov hlau hlau, txhuas cov hlau tsis muaj kuab paug muaj cov khoom qias neeg thiab cov hmoov txhuas uas muaj cov hlau hlau. Cov roj tsim tsim kom muaj kuab lom yog tshuaj lom, suav nrog cov pa roj xws li Rosin roj thiab zinc chloride.
