Puas tuaj yeem siv qhov chaw tsis muaj oxygen los ua kom sov cov hlau?
Soldering hlau tuaj yeem ua kom sov thaum tsis muaj oxygen. Vim tias cov pa oxygen tsis koom nrog cov txheej txheem cua sov ntawm cov hlau soldering.
Cov hluav taws xob soldering hlau yog rhuab los ntawm cov cua sov tshwm sim thaum tam sim no dhau los ntawm cov hlau tsis muaj hlau. Hluav taws xob soldering hlau tuaj yeem faib ua ob hom: hom cua sov sab hauv thiab sab nraud cua sov.
Cov cua sov sab nraud tso cov hlau nplaum rau ntawm qhov chaw ntawm lub cev cua sov. Vim hais tias cov cua kub los ntawm sab nraud ntawm lub taub hau ntawm lub taub hau, nws yog hu ua cov cua sov sab nraud. Cov cua sov sab hauv ua rau lub hau ntawm cov hlau soldering hollow, thiab cov khoom cua sov tau muab tso rau hauv kab noj hniav, yog li qhov ntim me me.
Txawm hais tias cov pa uas tau hais los ntawm qhov kev kawm tsis ua lub luag haujlwm hauv cov txheej txheem cua sov ntawm cov hlau soldering, nws tseem muaj "kev koom tes" hauv kev cuam tshuam nrog kev sib txuas thiab ua kom lub neej luv ntawm cov hlau.
Cov hlau cua sov hauv lub xeev kub yuav oxidize hauv ib puag ncig 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 soldering. Tsis tas li ntawd, cov pa oxygen kuj tseem yuav ua rau cov txheej txheem oxide tshwm rau ntawm qhov chaw molten tin thiab cov hlau yuav tsum tau welded, thaiv cov txheej txheem vuam. Vim li no, kev ua haujlwm soldering yog sib cais los ntawm flux, thiab nws txoj haujlwm yog los tiv thaiv oxidation.
Yog tias nws muaj peev xwm tsim tau 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 tib lub sijhawm nws tuaj yeem txuas lub neej kev pab cuam ntawm hluav taws xob soldering hlau. Tab sis tib neeg yuav tsum hnav lub ntsej muag oxygen.
Nyob rau hauv qhov tseeb siv hluav taws xob soldering hlau yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no
① Xaiv lub tshuab hluav taws xob hluav taws xob nrog lub zog tsim nyog, thiab tsis txhob overheat cov hlau soldering, txwv tsis pub nws yuav pov tseg hluav taws xob thiab ua kom cov txheej txheem oxidation thiab cuam tshuam rau vuam.
② Kawm saib thiab txiav txim qhov kub thiab txias ntawm cov khoom siv. Thaum qhov kub thiab txias yog qhov tsim nyog, qhov saum npoo yuav ci heev silvery dawb thiab muaj fluidity zoo. Yog tias qhov chaw hloov xim xiav sai sai, nws txhais tau hais tias qhov kub thiab txias dhau lawm, koj yuav tsum tau txo cov wattage los yog siv qhov kub thiab txias tsis tu ncua.
③ Tiv thaiv kev vibration hnyav. Vim tias cov ntaub ntawv kub-resistant siv los ua cov hlau cores yog ua los ntawm ceramics los yog mica, lawv yooj yim tawg thiab yuav tsum tau saib xyuas thaum siv lawv.
④ Nws yog nruj me ntsis txwv tsis pub siv acidic flux thaum soldering 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 ua tib zoo ntxuav nws, thiab thaum kawg siv rosin los pab ua kom tiav cov soldering.
