Cov hlau puas tuaj yeem ua kom sov hauv ib puag ncig yam tsis muaj oxygen?
Cov hlau nplaum tuaj yeem ua kom sov hauv qhov chaw tsis muaj oxygen. Vim tias cov pa oxygen tsis koom nrog cov txheej txheem cua sov ntawm cov hlau soldering.
Lub tshuab hluav taws xob siv hluav taws xob siv cov cua sov tshwm sim thaum hluav taws xob tam sim no dhau los ntawm cov hlau tsis muaj zog hlau kom sov. Hluav taws xob soldering hlau feem ntau tuaj yeem muab faib ua ob hom: hom cua sov sab hauv thiab sab nraud cua sov.
Cov cua sov sab nraud tso cov hlau taub hau rau hauv nruab nrab ntawm lub cev cua sov. Txij li thaum tshav kub kub los ntawm sab nraud ntawm lub taub hau soldering, nws yog hu ua cov cua sov sab nraud. Cov cua sov sab hauv ua rau lub hau ntawm cov hlau soldering rau hauv cov duab hollow, thiab cov khoom cua sov tau muab tso rau hauv cov kab noj hniav, yog li qhov ntim kuj sib xws.
Txawm hais tias cov pa oxygen uas tau hais los ntawm cov lus nug tsis ua lub luag haujlwm hauv cov txheej txheem cua sov ntawm cov hlau soldering, nws tseem ua rau "kev koom tes" zoo hauv kev cuam tshuam nrog vuam thiab ua kom lub neej ntawm cov hlau soldering.
Cov cua sov hlau ntawm qhov kub siab yuav oxidize nyob rau hauv ib qho chaw aerobic. Sij hawm dhau mus, txheej oxide yuav poob, ua rau cov cua sov hlau ua nyias thiab puas, thiab ua rau lub neej ua haujlwm luv ntawm cov hlau. Tsis tas li ntawd, cov pa oxygen kuj tseem yuav ua rau cov txheej txheem oxide tshwm rau ntawm qhov chaw ntawm cov molten tin thiab cov hlau raug welded, thaiv cov txheej txheem vuam. Vim li no, kev ua haujlwm soldering yog sib cais los ntawm flux, nws txoj haujlwm yog los tiv thaiv oxidation.
Yog tias peb tuaj yeem tsim qhov chaw tsis muaj pa oxygen rau vuam, nws yuav ua kom zoo dua qhov kev siv vuam zoo, vuam aluminium yuav dhau los ua cua, thiab nws tseem tuaj yeem txuas lub neej kev pab cuam ntawm cov hlau soldering.
Thaum siv cov hlau nplaum tiag tiag, ua tib zoo mloog cov ntsiab lus hauv qab no: 1. Xaiv cov hlau soldering uas tsim nyog wattage thiab tsis txhob overheat lub soldering hlau, txwv tsis pub nws yuav nkim hluav taws xob thiab ceev cov txheej txheem oxidation thiab cuam tshuam rau vuam. 2. Kawm los soj ntsuam thiab txiav txim qhov kub thiab txias ntawm solder. Thaum lub solder kub yog haum, qhov saum npoo yuav ci heev silvery dawb thiab muaj fluidity zoo. Yog tias qhov chaw hloov xim xiav sai sai, nws txhais tau tias qhov kub thiab txias siab dhau lawm thiab koj yuav tsum tau txo cov wattage los yog siv qhov kub thiab txias tsis tu ncua. ③ Tiv thaiv kev vibration hnyav. Vim hais tias cov ntaub ntawv kub-resistant siv los ua cov tub ntxhais hlau soldering yog ua los ntawm ceramic los yog mica, lawv tau yooj yim tawg, yog li tuav lawv nrog kev saib xyuas thaum siv lawv. ④ Nws yog nruj me ntsis txwv tsis pub siv acidic flux thaum vuam cov khoom siv hluav taws xob los tiv thaiv corrosion thiab to. Qhov zoo tshaj plaws flux yog rosin. Txawm li cas los xij, thaum vuam steel qhov chaw, yog tias muaj teeb meem hauv tinning, koj tuaj yeem siv cov kua qaub ua ntej ua cov tinning, ces ntxuav nws kom zoo, thiab thaum kawg siv rosin rau flux thiab solder tag.
