Thaum tsis muaj oxygen, cov hlau puas tuaj yeem ua kom sov?
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 hlau soldering yog rhuab los ntawm kev siv cov cua sov tshwm sim thaum lub hluav taws xob tam sim no dhau los ntawm cov hlau tsis muaj hlau. Soldering hlau tuaj yeem muab faib ua ob hom endothermic thiab exothermic.
Hom cua sov sab nraud tso lub taub hau hlau rau hauv qhov chaw nruab nrab ntawm lub cev cua sov, vim tias cov cua sov los ntawm sab nraud ntawm lub taub hau hlau, yog li nws yog hu ua cov cua sov sab nraud. Thiab cov cua sov sab hauv ntawm lub taub hau hlau rau hauv cov duab hollow, lub tshuab hluav taws xob cua sov tau muab tso rau hauv kab noj hniav, yog li qhov ntim ntau dua.
Cov ntsiab lus hais tias oxygen, txawm hais tias nyob rau hauv cov txheej txheem soldering hlau cua sov tsis ua ib lub luag hauj lwm, tab sis nyob rau hauv lub cuam tshuam soldering thiab shorten lub neej ntawm soldering hlau los yog ib tug zoo "paub".
Nyob rau hauv lub kub kub lub xeev ntawm cov hluav taws xob hlau nyob rau hauv lub oxygen ib puag ncig yuav tshwm sim oxidation tshwm sim, lub sij hawm lub sij hawm lub oxidation txheej tawm mus ua rau cov hluav taws xob hlau nyias, kev lim hiam, shorten lub neej kev pab cuam ntawm lub soldering hlau. Tsis tas li ntawd, cov pa oxygen kuj tseem yuav ua rau cov txheej txheem oxidized rau ntawm qhov chaw ntawm cov molten tin thiab cov hlau yuav tsum tau soldered, thaiv cov txheej txheem soldering. Vim li no, kev ua haujlwm soldering yog sib cais los ntawm cov flux, nws txoj haujlwm yog los tiv thaiv oxidation.
Yog tias koj tuaj yeem tsim qhov chaw tsis muaj pa oxygen rau cov khoom siv, nws yuav ua kom zoo dua ntawm cov khoom siv soldering, soldering aluminium kuj yuav ua kom yooj yim, tab sis kuj tseem txuas ntxiv lub neej ntawm cov hlau soldering.
Hauv kev siv tiag tiag ntawm cov hlau soldering yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no
① xaiv txoj cai wattage ntawm cov hlau soldering, tsis txhob ua rau cov hlau overheating, txwv tsis pub ob qho tib si pov tseg ntawm hluav taws xob kuj tseem yuav ua kom cov txheej txheem oxidation cuam tshuam rau vuam.
② Kawm los soj ntsuam thiab txiav txim qhov kub thiab txias ntawm lub solder. Thaum lub solder kub yog qhov tsim nyog, qhov saum npoo yuav ci heev nyiaj-dawb thiab muaj kev txav mus los zoo. Yog tias qhov chaw hloov xim xiav sai sai, qhov kub thiab txias siab dhau, yuav tsum tau txo cov wattage los yog hloov mus rau qhov kub thiab txias.
③ Tiv thaiv kev vibration hnyav. Vim tias cov khoom siv kub kub resistant ntawm cov tub ntxhais ntawm cov hlau soldering yog ua los ntawm ceramics los yog mica los ua, nws yooj yim tawg, thaum siv nws, tuav nws maj mam thiab muab tso tseg.
④Acidic flux yog nruj me ntsis txwv tsis pub thaum soldering cov khoom hluav taws xob tiv thaiv corrosion thiab to. Qhov zoo tshaj plaws flux yog rosin. Txawm li cas los xij, thaum soldering steel qhov chaw, xws li cov teeb meem tinning tuaj yeem siv ua ntej nrog acidic flux los ua txoj haujlwm zoo ntawm cov tin, thiab tom qab ntawd ua tib zoo ntxuav, thiab thaum kawg ua tiav nrog rosin flux.
