Yuav ua li cas solder aluminium Cheebtsam siv ib tug soldering hlau
Koj tuaj yeem ua cov txhuas txhuas nrog cov hlau thiab cov tin, qhov tseem ceeb yog siv cov flux tshwj xeeb kom tshem tawm cov oxide txheej ntawm aluminium. Aluminium lub tshav kub hloov mus yog ceev ceev, yog li siv lub zog hluav taws xob soldering hlau.
Aluminium vim cov tshuaj lom neeg ntawm cov nquag nquag, nyob rau hauv cov huab cua yuav sai sai oxidize lub nto los tsim ib tug ntom oxide txheej, nyob rau hauv lub aluminium welding thawj coated nrog soldering flux, thiab ces yuav kub soldering hlau dipped nyob rau hauv tag nrho cov tin thiab ces. muab tso rau hauv lub vuam rau preheating, ua kom kub nce, soldering flux los ntawm tuab mus rau nyias thiab ces ntxiv ib co soldering flux thiab solder, yog li ntawd lub solder yuav soldering hlau taub hau inclusive, thiab ces siv lub soldering hlau taub hau nyob rau hauv lub vuam ua ntej. thiab tom qab kev sib txhuam, qhov kev sib txhuam qhov deb yuav tsum tsis txhob loj heev, feem ntau ntawm 3 ~ 5mm ua rau lub taub hau ntawm cov hlau soldering, lub taub hau hlau soldering. 5 hli nruab nrab ntawm qhov kawg ntawm cov hlau soldering los txiav los ntawm aluminium oxide zaj duab xis rau saum npoo ntawm cov khoom siv txhuas. Vuam vim yog cov molten tin npog nrog huab cua cais tsis zoo yuav tsim cov oxide zaj duab xis tshiab thiab cov tin tuaj yeem tam sim ntawd tsuas yog tshem tawm cov oxide zaj duab xis ntawm cov khoom txhuas. Tos rau kem ntawm molten tin los ntawm lub pob mus rau hauv lub tiaj tus, qhia tau hais tias cov txhuas tau ruaj khov ua ke nrog tin, ces nres kev sib txhuam thiab so tawm cov seem solder thaum kub, thiab ces nrog ib tug pre-dipped tin hlau taub hau los yog lwm yam. Cheebtsam rau vuam yog yooj yim heev. Aluminium tuaj yeem welded los ntawm fusion vuam, siab vuam, lub melting point ntawm txhuas tsuas yog 660 degrees Celsius yog tsawg dhau rau brazing.
Ua ntej ntawm tag nrho cov, nyob rau hauv lub aluminium Cheebtsam ntawm weld ob peb tee ntawm dilute hydrochloric acid kom tshem tawm cov nto oxide zaj duab xis, tos ob peb lub sij hawm, thiab ces ntxiv ob peb tee ntawm thicker tooj liab sulfate tov, kom txog rau thaum lub weld yog tag nrho cov them nrog tooj liab. , dej los ntxuav tawm ntau tshaj tooj liab sulfate tov thiab hydrochloric acid tov, thiab ces 45-75W soldering hlau yuav welded, thiab nws cov nyhuv yog zoo.
Ib daim ntawm txhuas rau hauv qhov kub thiab txias melting, thiab tom qab ntawd ntxiv 2 mus rau 5 npaug ntawm cov tin melting yuav tsum tau siv, thiab tom qab ntawd raws li cov txheej txheem ntawm vuam yog yooj yim heev.
Nyob rau hauv kev kho mob ntawm huv si txhuas nto, coated nrog ib tug txheej ntawm mercuric nitrate tov, nrog ib tug 100w soldering hlau taub nyob rau hauv ntau noj tin, nrog ib tug soldering hlau taub nyob rau hauv lub soldering nto thaum txhuam sab ntawm mercuric nitrate tov yuav coated. . Qhov no tuaj yeem ruaj khov welded rau. Tab sis nco ntsoov: mercury yog tshuaj lom, yuav tsum tau welded nyob rau hauv qhov chaw ventilated, thiab tsis txhob siv cov tshuaj lom mercuric chloride.
Aluminium qhov chaw ntawm lub ntiaj teb txoj kev welding, pre-npaj pom iav fiber phaj ntawm dawb hmoov ua npuas ncauj, muab tso rau ntawm qhov chaw ntawm lub weld, nrog 75 w soldering hlau nyob rau hauv lub weld nto rub mus txog rau thaum aluminium nto txuas rau ib txheej ntawm tin, thiab tom qab ntawd siv ib daim ntaub yuav yog cov hmoov dawb ua npuas ncauj thiab rosin sib tov kom tshem tawm, tom qab ntawd muaj nyob rau hauv txoj kev dav dav ntawm vuam, kev coj ua ntawm txoj kev no yooj yim, cov nyhuv weld yog txaus siab. Kuj tseem tuaj yeem nqa rosin, hlau shavings sib xyaw, thiab tom qab ntawd siv cov ntawv xuab zeb los teeb lub teeb txhuas, cov rosin thiab hlau hmoov rau ntawm qhov chaw ntawm qhov vuam, nrog cov hlau nplaum rov sib txhuam kom ua rau cov txhuas saum npoo noj ib txheej ntawm tin, thiab tom qab ntawd raws li mus rau txoj kev dav dav ntawm vuam yuav ua tau du.
Aluminium qhov chaw ntawm qhov chaw weld polished ci ntsa iab, thiab tom qab ntawd ob peb tee ntawm lub tshuab xaws roj, cov roj ntau npaum li cas kom txaus, thiab tom qab ntawd siv rab riam ntse hauv qhov vuam rov qab ob peb zaug los txhuam, thiab tom qab ntawd siv ib rab riam ntse hauv qhov vuam rov qab ob peb zaug los txhuam, thiab tom qab ntawd siv ib rab riam ntse. hlau dipped nyob rau hauv solder thiab rosin nyob rau hauv lub weld rov qab thiab forth kev sib txhuam, lub tin yuav sai sai txuas mus rau lub txhuas qhov chaw, txoj kev kuj yog yooj yim dua, tswv yim.
Tin welding aluminium ntawm qhov chaw yog khoom, qhov tseeb, cov neeg kho tshuab lub zog yog tsawg heev, me ntsis loj dua yuav tev, qhov tseem ceeb yog tsim ntawm nws cov khoom sib txuas ua ke rau lub cev infiltration, vim yog ib feem ntawm oxide txheej barrier, tin thiab aluminium affinity kuj tsis zoo, lub weld nto yog tsis txaus los ua ke tsis tshua muaj zog.
