Puas muaj peev xwm ua kom sov cov hlau tsis siv oxygen?
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 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. Cov cua sov sab hauv ntawm lub taub hau ntawm lub taub hau 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, nyob rau lub sij hawm lub sij hawm lub oxidized txheej ntog tawm mus ua rau cov hluav taws xob hlau nyias, lim hiam, shorten lub neej kev pab cuam ntawm lub soldering hlau. Ntxiv nrog rau cov pa oxygen yuav ua rau cov molten tin thiab saum npoo ntawm cov hlau yuav tsum tau soldered oxidized txheej, thaiv cov txheej txheem soldering. Vim li no, kev ua haujlwm soldering yog sib cais los ntawm cov flux, nws lub luag haujlwm yog los tiv thaiv oxidation.
Yog tias koj tuaj yeem tsim qhov chaw tsis muaj pa oxygen rau kev vuam, nws yuav ua kom zoo dua ntawm kev siv vuam, vuam aluminium yuav ua kom yooj yim, tab sis kuj tseem yuav ua rau lub neej ntev ntawm cov hlau soldering. Tab sis ib tug yuav tau hnav lub npog ntsej muag oxygen.
Nyob rau hauv qhov tseeb siv ntawm cov hlau soldering yuav tsum tau xyuam xim rau cov nram qab no cov ntsiab lus ① xaiv txoj cai wattage ntawm lub soldering hlau, tsis txhob ua rau cov hlau overheating, txwv tsis pub ob qho tag nrho cov hluav taws xob pov tseg yuav ua rau kom cov txheej txheem oxidation cuam tshuam rau vuam ② kawm. saib thiab txiav txim qhov kub thiab fluidity 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 rau cov tub ntxhais ntawm cov hlau soldering yog ua los ntawm ceramics los yog mica, nws yooj yim tawg, yog li tuav nws maj mam thaum siv nws. 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 vuam 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 tag nrho nrog rosin flux.
