Lub tshuab hluav taws xob tuaj yeem ua kom sov hauv ib puag ncig yam tsis muaj oxygen
Ib qho hluav taws xob soldering hlau yog rhuab los ntawm cov cua sov tshwm sim thaum hluav taws xob tam sim no dhau los ntawm cov hlau tsis muaj hlau. Hluav taws xob soldering hlau feem ntau tuaj yeem muab faib ua ob hom: sab hauv rhuab thiab sab nraud.
Cov cua sov sab nraud tso lub taub hau ntawm lub taub hau ntawm qhov chaw ntawm cov cua sov, thiab hu ua cov cua sov sab nraud vim tias cov cua sov tuaj ntawm sab nraud ntawm lub taub hau hlau. Cov cua sov sab hauv ua rau lub taub hau ntawm lub taub hau rau hauv cov duab hollow, thiab cov khoom cua sov tau muab tso rau hauv cov kab noj hniav, yog li qhov ntim me me.
Cov pa oxygen hais los ntawm tus neeg nug, txawm hais tias tsis ua lub luag haujlwm hauv cov txheej txheem cua sov ntawm cov hlau soldering, tseem ua rau muaj txiaj ntsig zoo hauv kev cuam tshuam nrog vuam thiab ua kom lub neej ntev ntawm cov hlau soldering.
Hluav taws xob cua sov xov hlau uas nyob rau hauv qhov kub thiab txias yuav muaj oxidation nyob rau hauv ib qho chaw aerobic. Thaum lub sij hawm, cov oxide txheej poob, ua rau cov hluav taws xob cua sov hlau ua nyias thiab puas, ua rau lub neej ntawm cov hlau soldering. Tsis tas li ntawd, cov pa oxygen kuj tuaj yeem ua rau cov txheej txheem oxide tshwm rau ntawm qhov chaw molten tin thiab cov hlau soldered, thaiv cov txheej txheem vuam. Vim li no, kev ua haujlwm ntawm cov hlau tsis tuaj yeem raug cais tawm ntawm cov hlau nplaum, nws txoj haujlwm yog los tiv thaiv oxidation.
Thaum siv hluav taws xob soldering hlau hauv kev xyaum, yuav tsum tau them nyiaj rau cov ntsiab lus hauv qab no: ① Xaiv qhov tsim nyog wattage ntawm cov hlau soldering, tsis txhob overheat cov hlau soldering, txwv tsis pub nws yuav tsis tsuas nkim hluav taws xob hluav taws xob tab sis kuj ua kom cov txheej txheem oxidation thiab cuam tshuam. vuam; ② Kawm los soj ntsuam thiab txiav txim qhov kub thiab txias ntawm solder. Thaum qhov kub thiab txias yog qhov tsim nyog, qhov saum npoo yuav tshwm xim dawb dawb thiab muaj fluidity zoo. Yog tias qhov chaw hloov xim xiav sai sai, nws qhia tau hais tias qhov kub thiab txias siab dhau lawm, thiab nws yog ib qho tsim nyog yuav tsum tau txo cov wattage los yog hloov mus rau qhov kub thiab txias ntawm soldering hlau tiv thaiv kev vibration loj. Vim hais tias cov ntaub ntawv kub-resistant siv los ua cov hlau cores yog ua los ntawm ceramics los yog mica, lawv tau yooj yim tawg thiab yuav tsum tau saib xyuas thaum siv Nws yog nruj me ntsis txwv tsis pub siv acidic soldering flux thaum vuam cov khoom siv hluav taws xob tiv thaiv corrosion thiab leak. Qhov zoo tshaj plaws flux yog rosin. Tab sis thaum welding steel Cheebtsam, yog hais tias muaj teeb meem nyob rau hauv soldering, acidic soldering flux yuav siv tau ua ntej ua lub soldering ua hauj lwm zoo, ces ua tib zoo ntxuav nws, thiab thaum kawg siv rosin soldering kom tiav weld.
