2 yog vim li cas lub hau ntawm cov hlau soldering tsis noj cov tin
1. Pheej yig sab hauv cua sov uas tsis muaj zog soldering hlau
Lub taub hau ntawm lub tshuab hluav taws xob sab hauv no yog ua los ntawm tooj liab thiab tsis muaj qhov kub thiab txias, thiab nws tuaj yeem kho qhov kub thiab txias.
Tom qab no hom hluav taws xob soldering hlau yog energized rau ib lub sij hawm ntawm lub sij hawm, qhov kub ntawm lub soldering hlau taub yuav nce siab thiab siab dua. Nyob rau hauv qhov kub kub, tooj liab soldering hlau taub yog nquag oxidation thiab blackening. Txawm hais tias lub taub hau hlau yog polished nrog cov ntawv xuab zeb lossis cov ntaub ntawv, nws tseem yuav oxidize thiab tig dub tom qab lub sijhawm luv luv.
Yog tias nws muaj tseeb tias kev siv cov hlau nplaum pheej yig tau ua rau lub taub hau ntawm lub taub hau ua oxidized thiab blackened, nws raug nquahu kom hloov cov hlau soldering. Nws yog qhov zoo tshaj plaws los siv qhov kub thiab txias tsis tu ncua ntawm soldering hlau los yog adjustable kub soldering hlau. Piv txwv li, lub taub hau ntawm 936 kub-kho tau soldering hlau tuaj yeem hloov tau thiab tuaj yeem ua ntau yam duab, uas tuaj yeem xaiv raws li qhov xav tau ntawm vuam. Hom no lub taub hau hlau yog ua los ntawm cov khoom siv hlau thiab tsis yooj yim oxidized ntawm qhov kub thiab txias. Raws li ntev raws li lub taub hau hlau tsis corroded los ntawm acidic flux thiab tsis tas yuav tsum tau rhuab nrog kub yaj kua nplaum los yog yas, lub taub hau hlau soldering tau yooj yim tinned.
2. Siv cov kua qaub los yog cov hlau nplaum uas muaj cov impurities ntau dhau
Ntau tus novice welders nyiam siv acidic solder paste li flux thaum vuam. Cov flux no yog me ntsis acidic thiab corrosive rau qee cov lus qhia tsis zoo ntawm cov hlau.
Nws raug nquahu kom siv cov block rosin lossis rosin cawv ua kua dej thaum soldering.
Tsis tas li ntawd, pheej yig solder hlau muaj ntau yam impurities, thiab siv hom solder hlau no kuj yuav ua rau cov hlau taub hau tsis noj tin.
Cov hlau nplaum zoo li no muaj qhov tsis zoo wettability thiab fluidity tom qab melting, thiab cov pob qij txha yog tsaus, tsis du thiab ci. Yog hais tias lub taub hau hlau tsis nqus cov tin vim qhov tsis zoo ntawm cov hlau tsis zoo, nws raug nquahu kom siv cov khoom zoo uas tsis tshua muaj melting point solder hlau thaum vuam.
