Yuav ua li cas weld aluminium qhov chaw nrog hluav taws xob soldering hlau
Hauv xov tooj cua thiab cov khoom siv hauv tsev, qee zaum yuav tsum tau vuam cov khoom siv txhuas me me vim tias qhov chaw ntawm cov khoom siv txhuas tau yooj yim oxidized, ua rau nws nyuaj rau cov neeg pib siv vuam khov kho. Tus sau tau xa mus rau cov khoom siv aluminium vuam thiab ua tiav los ntawm kev sim. Tsab ntawv xov xwm no qhia txog ntau txoj hauv kev rau soldering aluminium nrog tin rau siv.
Ua ntej, siv vuam flux mus rau qhov chaw vuam ntawm cov khoom siv txhuas, tom qab ntawd tsau cov hlau kub kub hauv tin thiab preheat nws ntawm qhov chaw vuam. Thaum qhov kub thiab txias, cov kua nplaum nplaum yuav thicker thiab thinner, thiab tom qab ntawd ntxiv ib co soldering flux thiab soldering tin los npog lub taub hau hlau. Tom qab ntawd, siv lub taub hau hlau rau kev sib txhuam ua ntej thiab tom qab vuam qhov chaw, thiab qhov kev sib txhuam deb yuav tsum tsis txhob loj dhau. Feem ntau, aluminium oxide zaj duab xis nyob rau saum npoo ntawm cov khoom siv txhuas yuav tsum tau khawb ntawm lub taub hau hlau ntawm 3 thiab 5 hli.
Vim muaj cov molten tin npog thiab huab cua sib cais ntawm qhov chaw vuam, nws tsis tuaj yeem tsim cov oxide zaj duab xis tshiab, thaum cov tin tuaj yeem ua raws li cov txhuas qhov chaw uas nyuam qhuav raug tshem tawm ntawm oxide zaj duab xis.
Tos kom lub molten tin hloov los ntawm ib tug kheej kheej kheej kheej mus rau lub tiaj tus qhia tau hais tias lub txhuas tivthaiv tau ruaj khov kho nrog lub tin. Thaum lub sijhawm no, nres kev sib txhuam thiab so tawm cov khoom seem thaum nws kub. Tom qab ntawd, nws yog qhov yooj yim rau welding nrog pre dipped tin hlau taub hau lossis lwm yam khoom.
Thib ob, 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 saum npoo. Tos ib pliag, ces ntxiv ob peb tee ntawm concentrated tooj liab (II) sulfate tov. Thaum lub vuam taw tes tau them tag nrho nrog tooj liab, ntxuav tawm ntau tshaj tooj liab (II) sulfate tov thiab hydrochloric acid tov nrog dej, thiab tom qab ntawd siv 45-75W soldering hlau los vuam. Cov nyhuv yog qhov zoo.
Thib peb, muab ib daim ntawm txhuas thiab muab tso rau hauv lub crucible rau cua sov thiab melting, ces ntxiv 2-5 lub sij hawm tus nqi ntawm tin kom yaj thiab siv nws. Vuam raws li cov txheej txheem yog yooj yim heev.
Plaub, siv ib txheej ntawm Mercury (II) nitrate tov rau ntawm qhov chaw huv si, siv 100w soldering hlau taub hau noj ntau tin, thiab siv lub taub hau hlau los txhuam thiab siv cov tshuaj Mercury (II) nitrate rau ntawm qhov chaw vuam. Qhov no tso cai rau ib tug ruaj khov soldering.
Lus Cim: Mercury yog tshuaj lom. Vuam yuav tsum tau ua nyob rau hauv qhov chaw ventilated, thiab yuav tsum tsis txhob siv cov tshuaj lom Mercury (II) chloride.
Fifthly, rau vuam ntawm txhuas qhov chaw siv lub ntiaj teb txoj kev, npaj cov hmoov dawb ua npuas ncauj rau sawing lub fiberglass board ua ntej, muab tso rau saum npoo ntawm lub vuam qhov chaw, siv ib tug 75W soldering hlau mus rau lub welding nto mus rau ib txheej. ntawm tin yog txuas rau ntawm txhuas nto, thiab tom qab ntawd siv ib daim ntaub los tshem tawm qhov sib xyaw ntawm cov hmoov dawb ua npuas ncauj thiab rosin. Hauv qhov no, tib txoj kev 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 pom zoo kom sib tov rosin thiab cov ntaub ntawv hlau, thiab tom qab ntawd siv cov ntawv xuab zeb los txhuam qhov saum npoo ntawm txhuas. Muab rosin thiab hlau hmoov rau ntawm qhov chaw du ntawm qhov sib koom ua ke, rub ntau zaus nrog cov hlau nplaum ua kom cov txhuas saum npoo noj ib txheej ntawm cov tin, thiab tom qab ntawd ua raws li cov txheej txheem ib txwm ua kom zoo welding.
Thib rau, ua ntej polish qhov saum npoo ntawm qhov vuam cheeb tsam ntawm cov khoom siv txhuas, tom qab ntawd tso ob peb tee ntawm lub tshuab xaws roj nrog cov roj txaus. Tom qab ntawd siv ib rab riam ntse los txhuam qhov vuam qhov chaw rov qab thiab tawm ob peb zaug, thiab tom qab ntawd siv cov hlau nplaum dipped rau hauv cov tin thiab rosin los txhuam rov qab rau ntawm qhov chaw vuam. Lub tin yuav ceev nrooj ua raws li cov khoom siv txhuas, uas kuj yog qhov yooj yim thiab siv tau.
