Yuav ua li cas weld aluminium qhov chaw nrog ib tug soldering hlau?
Hauv kev saib xyuas cov 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, nws yog ib qho nyuaj rau cov neeg pib siv vuam khov kho. Tus sau tau xa mus rau cov ntaub ntawv tseem ceeb ntawm aluminium welding thiab ua tiav los ntawm kev sim. Tsab ntawv xov xwm no qhia txog cov tswv yim ntawm kev siv aluminium rau kev siv.
Ua ntej, siv cov flux mus rau qhov chaw vuam ntawm cov khoom siv txhuas, tom qab ntawd muab cov hlau kub kub tso rau hauv lub tin thiab muab tso rau ntawm qhov chaw soldering rau preheating. Thaum qhov kub thiab txias, lub solder yuav thinner, ntxiv ib co flux thiab solder, ua lub soldering hlau npog lub soldering hlau taub, thiab ces rub lub soldering hlau taub rov qab mus rau lub vuam taw tes. Qhov kev sib txhuam deb yuav tsum tsis txhob loj dhau. Feem ntau, qhov kev sib txhuam deb ntawm 3 mus rau 5 hli los ua kom cov hlau taub hau khawb cov aluminium oxide zaj duab xis rau saum npoo ntawm cov khoom siv txhuas.
Vim tias qhov chaw vuam yog npog nrog cov molten tin thiab cais tawm ntawm huab cua, nws tsis tuaj yeem tsim cov oxide zaj duab xis tshiab, thiab cov tin tuaj yeem tam sim ntawd lo rau cov khoom txhuas nrog cov oxide zaj duab xis uas nyuam qhuav raug tshem tawm.
Thaum cov kab ntawm molten tin hloov los ntawm cov duab kheej kheej mus rau lub tiaj tus, nws qhia tau hais tias cov txhuas feem tau ruaj khov ua ke nrog cov tin. Nyob rau lub sijhawm no, nres rub thiab so tawm cov khoom seem thaum nws kub, thiab tom qab ntawd txuas nrog cov hlau lead lossis lwm yam khoom uas tau dipped hauv tin ua ntej. Nws yooj yim heev.
Thib ob, tso ob peb tee ntawm dilute hydrochloric acid rau ntawm qhov sib koom ua ke ntawm cov khoom siv txhuas kom tshem tawm cov oxide zaj duab xis saum npoo. Tos ib pliag, tom qab ntawd ntxiv ob peb tee ntawm concentrated tooj liab sulfate tov. Thaum lub vuam sib koom ua ke tag nrho nrog tooj liab, ntxuav tawm cov tshaj nrog dej. tooj liab sulfate tov thiab hydrochloric acid tov, thiab ces siv ib tug 45-75W soldering hlau rau solder, thiab cov nyhuv yog zoo.
Thib peb, muab ib daim ntawm txhuas thiab muab tso rau hauv lub crucible kom sov thiab yaj nws. Tom qab ntawd ntxiv 2 mus rau 5 zaug ntawm tin kom yaj nws thiab muab tso rau ib sab. Nws yog qhov yooj yim heev rau welding nws raws li txoj kev pa.
Plaub, siv ib txheej ntawm mercury nitrate tov rau ntawm qhov chaw huv si, siv 100w soldering hlau taub kom nqus tau ntau cov tin, thiab rub cov hlau nplaum rau ntawm qhov chaw vuam thaum siv cov tshuaj mercury nitrate. Qhov no yuav tso cai rau ib tug ruaj welding.
Lus Cim: Mercury yog tshuaj lom. Vuam yuav tsum tau ua nyob rau hauv ib qho chaw ventilated thiab tsis txhob siv cov tshuaj lom mercury chloride.
Thib tsib, welded aluminium qhov chaw siv cov txheej txheem hauv zos. Npaj cov hmoov dawb los ntawm sawing lub fiberglass board ua ntej, muab tso rau ntawm qhov chaw ntawm lub vuam sib koom tes, siv 75w soldering hlau los txhuam cov vuam nto nyuaj kom txog rau thaum ib txheej ntawm cov tin txuas nrog cov txhuas nto, thiab tom qab ntawd siv daim ntaub. Tom qab kev sib xyaw ntawm cov hmoov dawb thiab rosin 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.
Koj tuaj yeem sib tov rosin thiab hlau filings, tom qab ntawd txhuam cov npoo ntawm txhuas nrog cov ntawv xuab zeb, tso cov rosin thiab hlau hmoov rau ntawm qhov chaw du ntawm qhov sib koom ua ke, rub nws ntau zaus nrog cov hlau soldering kom coated aluminium nto nrog ib txheej. ntawm tin, thiab tom qab ntawd ua raws li txoj kev qub. Smooth vuam.
Thib rau, ua ntej polish qhov saum npoo ntawm cov vuam sib koom ua ke ntawm cov khoom txhuas ci ntsa iab, tom qab ntawd ntxiv ob peb tee ntawm lub tshuab xaws roj, cov roj yuav tsum txaus, ces siv rab riam ntse los txhuam rov qab rau ntawm qhov sib txuas ob peb zaug. , thiab ces siv ib tug soldering hlau dipped nyob rau hauv solder thiab rosin khiav rov qab thiab tawm ntawm lub vuam sib txuas. Los ntawm kev sib txhuam, cov tin yuav nrawm nrawm rau cov khoom txhuas. Txoj kev no kuj yog ib qho yooj yim thiab siv tau.
