Soldering yog cov txheej txheem ntawm kev sib txuas cov khoom ua los ntawm cov khoom sib txawv los ntawm kev qhia txog kev sib txuas ntawm lawv. Tsis tas li ntawd, cov khoom siv no muaj qhov melting point qis dua li ntawm lwm qhov chaw. Xws li kev ua haujlwm yog dav siv los ua txoj kev sib txuas zoo tshaj plaws. Soldering tooj liab kav tso cai rau koj mus cuag lub neej kev pab cuam ntawm xws li ib tug kev twb kev txuas, nruj ntawm nws seams nyob rau hauv lub siab, thiab xyuas kom meej siab tiv thaiv corrosion.
Ua ntej koj pib ua haujlwm ntawm koj tus kheej, nws raug nquahu kom paub koj tus kheej kom paub meej nrog lawv cov khoom tseem ceeb txhawm rau tiv thaiv qhov tsis xav tau thiab xaus nrog kev sib txuas zoo.
Cov kav dej tooj liab yog soldered nrog muag muag lossis tawv tawv. Cov khoom siv thawj zaug yog siv rau ntawm qhov kub ntawm li 425 ° C, thiab qhov tso cai ntawm qhov thib ob tuaj yeem ncav cuag 560 ° C. Kev txiav txim siab ntawm hom solder nyob ntawm tus nqi ntawm tooj liab thiab lwm yam ntaub ntawv uas muaj nyob rau hauv nws muaj pes tsawg leeg. Nyob rau hauv rooj plaub uas cov yeeb nkab tooj liab solder muaj nyiaj, nws cov ntsiab lus melting yuav tsum tau qis dua.
Yuav kom tau txais kev sib txuas zoo dua, nws yog qhov zoo tshaj los siv tooj liab-phosphoruscov ntsiab lus, tab sis lawv cov ntsiab lus melting yog ntau dua li cov nyiaj. Rau cov khoom siv tooj liab-bronze thiab tooj liab-brass molten, flux yog siv los ua cov kav tooj liab. Nws txoj kev siv yog sib npaug rau kev siv tshuab ntxhua khaub ncaws ua ntej ua cov txheej txheem uas tiv thaiv cov tsos ntawm oxide zaj duab xis, uas yog qhov tseem ceeb heev rau cov txheej txheem no. Cov flux feem ntau yog siv, uas muaj cov tsos ntawm cov muab tshuaj txhuam, ua tsaug rau qhov uas cov yeeb nkab tooj liab yuav yooj yim heev.
Yuav kom tsis txhob ua yuam kev hauv kev sib txuas, koj kuj yuav tsum ua raws qee cov cai. Kev sib txuas yuav tsum tau muab ntxuav nrog cov nplaim hluav taws txo qis uas yuav ua kom muaj cua sov siab tshaj plaws. Nws yog tsim nyog los degrease hlau nto. Qhov sib txawv ntawm cov khoom thiab lawv qhov chaw txheeb ze yuav tsum tau ua tib zoo xyuas.
Soldering tooj liab kav yuav siv me me ntawm flux los ntawm sab nraud ntawm kev sib koom tes. Tsis tas li ntawd, qhov chaw rau qhov no yuav tsum tau muab sib npaug rau qhov kub thiab txias. Tom qab ntawd lub solder tuaj yeem siv rau kev sib koom ua ke thiab sib npaug sib npaug hauv nws siv lub teeb taws. Thaum molten, nws yuav ntws mus rau qhov sib tshuam, uas yog kub dua.
Tom qab soldering tiav, flux residues yuav tsum tau muab tshem tawm. Nws yog ib qho tseem ceeb heev uas yuav tsum tau ua raws li ib qho ntawm cov cai tseem ceeb: lub voj voog cua sov yuav tsum tsis txhob siv sij hawm ntev, thiab overheating tsis suav nrog tag nrho thaum ua haujlwm. Tsis tas li ntawd, qhov cua txaus yuav tsum tau ua kom tiavtiv thaiv qhov tshwm sim ntawm cadmium vapor, uas muaj teeb meem rau tib neeg lub cev.
Ua raws li cov lus pom zoo saum toj no yuav ua kom yooj yim rau kev ua haujlwm, txuag sijhawm thiab pab ua tiav qhov xav tau.
