Tin thiab soldering hlau tuaj yeem siv los ua aluminium. Qhov zais cia yog tshem tawm cov txheej txheem aluminium oxide siv cov flux tshwj xeeb. Siv lub tshuab hluav taws xob siab zog vim aluminium heats sai sai.
Aluminium yuav sai sai oxidize nyob rau hauv cov huab cua kom tsim ib tug ntom oxide txheej rau saum npoo vim nws cov yam ntxwv ntawm cov tshuaj lom neeg heev. Siv cov flux ua ntej mus rau qhov chaw vuam aluminium ua ntej dipping cov hlau kub kub hauv tin thiab teeb tsa rau ntawm qhov chaw vuam kom preheat. Flux thins thiab thickens raws li qhov kub thiab txias, yog li ntxiv cov flux thiab tin rau lub hau ntawm cov hlau soldering nrog solder. Rub lub taub hau ntawm cov hlau soldering ob qho tib si ua ntej thiab tom qab welding.Qhov kev pom zoo ntau yam rau qhov kev sib txhuam ntawm qhov deb ntawm 3 mus rau 5 hli. Cov txhuas oxide tso rau ntawm qhov khoom ntawm qhov chaw yog khawb ntawm qhov taw tes no los ntawm cov hlau taub hau. Nws tsis tuaj yeem tsim cov oxide zaj duab xis tshiab ntawm qhov chaw vuam vim yog cov molten tin npog thiab cais tawm ntawm huab cua, thiab cov tin tuaj yeem kov cov txhuas seem nrog cov oxide txheej uas tsis ntev los no tau muab tshem tawm hauv lub sijhawm.Thaum lub molten tin transforms los ntawm ib tug kheej kheej mus rau lub tiaj tus duab, nws tau ntse txuas nrog cov khoom siv txhuas. Tsis txhob txhuam ntawm lub sijhawm no, tshem tawm cov dej ntws tawm thaum nws tseem kub, thiab tom qab ntawd siv cov hlua hlau ua ntej los yog lwm qhov chaw. Nws yog qhov ua tau tiag tiag. Fusion welding thiab siab vuam yog ob txoj hauv kev rau kev koom nrog txhuas. Brazing tsis tuaj yeem ua tau vim tias txhuas muaj qhov tsis txaus melting point (660 degrees Celsius).
Ua ntej, tso ob peb tee ntawm dilute hydrochloric acid ntawm qhov chaw vuam ntawm cov khoom siv txhuas kom tshem tawm cov oxide zaj duab xis ntawm qhov chaw. Tom qab ib ntus, ntxiv ob peb tee ntawm cov tshuaj concentrated tooj liab sulfate. Thaum qhov chaw vuam yog tag nrho cov tooj liab, ntxuav tawm cov sulfuric acid ntau dhau nrog dej. tooj liab tov thiab hydrochloric acid tov, thiab ces soldering nrog ib tug 45-75W soldering hlau, cov nyhuv yog zoo.
Ib daim ntawm txhuas yog rhuab thiab melted nyob rau hauv lub crucible, thiab ces 2 mus rau 5 lub sij hawm ntawm tin yog ntxiv rau yaj rau tom qab siv, thiab ces nws yog heev yooj yim mus welding raws li cov pa txoj kev.
Nyob rau ntawm qhov chaw huv huv, siv ib txheej ntawm cov tshuaj mercuric nitrate, siv 100w soldering hlau taub kom noj ntau cov tin, thiab siv lub taub hau hlau los txhuam cov nplaum nplaum thaum siv cov tshuaj mercuric nitrate. Qhov no tuaj yeem ruaj khov welded rau. Tab sis nco ntsoov: Mercury yog tshuaj lom, yog li nws yuav tsum tau welded nyob rau hauv ib qho chaw ventilated, thiab tsis txhob siv cov tshuaj lom mercuric chloride.
Vuam txhuas qhov chaw los ntawm txoj kev hauv av, npaj cov hmoov dawb rau sawing iav fiber ntau lub rooj tsavxwm ua ntej, muab tso rau ntawm qhov chaw vuam, rub nws rau ntawm qhov chaw vuam nrog 75w soldering hlau kom txog rau thaum txheej txheej ntawm cov tin txuas rau ntawm qhov chaw vuam. , thiab tom qab ntawd siv daim ntaub tshem tawm cov hmoov dawb thiab Tom qab cov rosin sib tov raug tshem tawm, txoj kev dav dav tuaj yeem siv rau vuam. Tom qab kev xyaum, txoj kev no yog yooj yim thiab cov nyhuv vuam yog txaus siab. Nws kuj tseem tuaj yeem sib tov rosin thiab hlau filings, tom qab ntawd polish lub npoo ntawm txhuas qhov chaw nrog cov ntawv xuab zeb, muab cov rosin thiab hlau hmoov rau ntawm qhov chaw du ntawm qhov chaw vuam, thiab rov ua dua nrog cov hlau soldering kom ua rau cov khoom siv txhuas. ib txheej ntawm tin, thiab tom qab ntawd ua raws li txoj kev dav dav. Smooth vuam.
Qhov saum npoo ntawm qhov vuam ntawm cov txhuas qhov chaw yog polished ci ntsa iab, thiab tom qab ntawd tso ob peb tee ntawm lub tshuab xaws roj, cov roj yuav tsum txaus, ces siv rab riam ntse los txhuam rov qab los ntawm qhov chaw vuam ob peb zaug, thiab tom qab ntawd muab cov hlau ntxig rau hauv cov hlau thiab cov rosin thiab rub rov qab los ntawm qhov chaw vuam, cov tin yog ceev heev Nws yuav ruaj khov rau cov khoom siv txhuas, thiab txoj kev no kuj yog qhov yooj yim thiab siv tau.
Qhov saum npoo ntawm tin-soldered aluminium zoo nkaus li khov kho, tab sis qhov tseeb lub zog ntawm cov neeg kho tshuab yog tsawg heev, thiab cov kua muag loj me ntsis yuav tev tawm. Qhov tseem ceeb yog qhov complex tsim ntawm qhov chaw sib txuas yog lub cev infiltration. Vim yog qhov thaiv ntawm ib feem ntawm oxide txheej, affinity ntawm tin thiab aluminium Nws kuj tsis zoo, qhov vuam nto tsis muaj kev sib koom ua ke, thiab lub zog tsawg heev.
