Brazing

Copper-phosphorus brazing alloys (pamanja ndi ng'anjo)

Phosphorous mu aloyi zamkuwa-phosphorous imapangitsa kuti alloy adzivula okha pa mkuwa wofiira. Amapangidwira misonkhano yamkuwa-mkuwa ndi yamkuwa pogwiritsa ntchito pickling flux. Amagwiritsidwa ntchito makamaka pamayendedwe oyendera madzimadzi opangidwa ndi mkuwa. Malo osungunuka a ma aloyi athu amatsimikizika pa +/- 3 ° C.

Mafomu:

• Ndodo zopanda kanthu + pickling flux (phala ndi ufa)

Copper-Phosphorus-Silver brazing alloys

Kuphatikiza kwa siliva ku ma alloys amkuwa-phosphorous kumachepetsa kutentha kwawo kwa liquidus. Kuphatikizikaku kumayeretsanso mbewu, kumapangitsa kuti magetsi aziyenda bwino ndikuwonjezera ductility ya alloy. Amapangidwa makamaka pamisonkhano ya Copper-Copper ndi Copper-Brass pogwiritsa ntchito pickling flux.

Mafomu:

• Ndodo zopanda kanthu + pickling flux (phala ndi ufa)
• Zokutidwa ndi ndodo

ma aloyi otentha

Ma alloys a brazing amalola kuphatikiza chitsulo, mkuwa ndi chitsulo chosungunula, matako mpaka kumatako komanso pama diameter akulu a machubu. Mphamvu zawo zamakina apamwamba, zotsatira zake zokongola, kugwiritsa ntchito kwake mosavuta komanso mawonekedwe awo azachuma kwambiri, zimawapangitsa kukhala oyenera magawo angapo a zochitika.

Mafomu:

• Ndodo zopanda kanthu + zovula zotuluka (phala ndi ufa)
• Zokutidwa ndi ndodo

Silver Brazing Alloys

Ma aloyi asilivawa amagwiritsidwa ntchito popanga braze: Chitsulo, chitsulo chosapanga dzimbiri, mkuwa, mkuwa, faifi tambala ndi mkuwa, zitsulo zonse zachitsulo komanso zopanda chitsulo (kupatula aluminium ndi manganese). Kukhalapo kwa siliva wochuluka kwambiri kupanga ma aloyi ndi kumapangitsa kuti kutentha kusungunuke kutsika. Pali mitundu iwiri ya ogulitsa siliva: Ternary solders (wopangidwa ndi Silver, Copper ndi Zinc) ndi quaternary solders (wopangidwa ndi Silver, Copper, Zinc ndi Tin).

Silver brazing alloys amalimbikitsidwa panjira zonse zowotcha. Ndodo zokutira za BRAZARGENT® ndi ndodo za TBW zimalola kugwiritsa ntchito zinthu zowotcha mosavuta, osayang'anira kutulutsa kwamagetsi pamanja.

Mafomu:

• Ndodo zopanda kanthu + zochotsa zotulutsa (phala ndi ufa)
• Zokutidwa ndi ndodo
• Ndodo za TBW (waya za tubular brazing)
• Preforms (mphete, matikiti)

Aluminium Brazing

Ma aloyi athu (Aluminium-Silicon ndi Zinc-Aluminiyamu) amaphimba ntchito zambiri zopangira zida za aluminiyamu pamodzi kapena ndi zida zina. Zotukuka zomwe zidapangidwa kuti zifewetse komanso kukhathamiritsa kugwiritsa ntchito mitundu iyi ya brazing (TBW (tubular wire) ndi TBM (composite wire) matekinoloje amapereka bata, kubwereza, komanso kupindula panthawi yamagetsi.

Mafomu:

• Ndodo zopanda kanthu + flux stripper (phala ndi ufa)
• Zokutidwa ndi ndodo
• Ndodo za TBW (waya za tubular brazing)
• ndodo za TBM (waya zomangirira)
• Preforms (mphete)

Pickling mtsinje

Flux iyenera kusungunula ma oxide otsala, kuchuluka kwake kwamadzimadzi kumawongolera woyendetsa poyambitsa zitsulo zodzaza. Kusinthasintha kwabwino kumachedwetsa kusungunuka kwa zinthu. Chitsulocho chikasungunuka, zina mwazomwe zimatuluka zimasungunuka ndipo zina zimakhala zotsalira. Pambuyo pakuwotcha, mbalizo zimatsukidwa ndi flux (zotsalira) ndikutsuka ndi madzi otentha kapena makina.

Mitundu yosiyanasiyana yazinthu zopangira, zopaka utoto ndi ma CD zitha kuperekedwa.

(Maphunziro achitika popempha)

Mafomu:

• Flux mu gel, phala ndi mawonekedwe a ufa
