Brazing

Mitundu yayikulu kwambiri yazinthu zopangira ma brazing zomwe zimagawidwa ndi ma alloys

Selectarc ili ndi luso lazaka makumi asanu ndi awiri, kuphatikiza kupanga ma aloyi a CupP brazing ndi zinthu zatsopano monga waya wa tubular brazing (waya wonyezimira) mu siliva, aluminiyamu ndi kompositi (aluminiyamu aloyi ndi kutuluka).

Zaka 70 zakuchita bwino popanga zinthu zogulitsa ku Europe

Ndi zipangizo zamakono zopangira zinthu, Selectarc imapanga ma alloys olimba komanso amtundu wa solder (alloys ndi fluxes) kuti athetse njira zamakampani komanso mphete zogulitsira zolondola ndi zowonetseratu. Zomwe takumana nazo mu brazing ndi gulu laukadaulo lopangidwa ndi madotolo afizikiki ndi chemistry ndi mainjiniya, zimatilola kukhalapo m'magawo akulu otsatirawa:

  • Mphamvu zongowonjezedwanso, mapanelo adzuwa
  • Galimoto
  • Kutentha ndi mpweya wabwino
  • Makina oziziritsa mpweya, m'nyumba ndi m'mafakitale
  • Ukhondo Plumbing
  • Zida za Carbide ndi diamondi
  • Zida zoyezera ndi zowongolera
  • Zomangamanga zamagetsi
  • Zomangamanga za tubular

Copper-Phosphorus solders (pamanja ndi ng'anjo)

Phosphorus yomwe ili mu Copper-Phosphorus alloys imapangitsa kuti alloy adzivula okha pa mkuwa wofiira. Amapangidwa makamaka pamisonkhano ya Copper-Copper ndi Copper-Brass pogwiritsa ntchito kutulutsa kotulutsa. Ntchito yaikulu yoyendera mabwalo amadzimadzi opangidwa ndi mkuwa. Malo osungunuka a ma aloyi athu amatsimikizika pa +/- 3 ° c.

Mawonekedwe:
  • Bare baguettes + kuvula flux (phala ndi ufa)

Copper-Phosphorus-Silver solders

Kuwonjezera kwa siliva mu Copper-Phosphorus alloys amachepetsa kutentha kwa liquidus kwake. Kuphatikiza uku kumapangitsanso kuyeretsa njere, kupititsa patsogolo kayendedwe ka magetsi komanso kuonjezera ductility ya alloy. Amapangidwa makamaka pamisonkhano ya Copper-Copper ndi Copper-Brass pogwiritsa ntchito kutulutsa kotulutsa.

Brazing solders

Ma alloys a brazing amalola kusonkhana kwachitsulo, mkuwa, chitsulo chosungunula, kumapeto mpaka kumapeto komanso pamtunda waukulu wa chubu. Kukaniza kwawo kwamakina, kukongola kwake, kugwiritsa ntchito kwake mosavuta komanso momwe amapezera ndalama zambiri, zimawapangitsa kukhala oyenera magawo angapo a zochitika.

Silver solders

Ma aloyi asilivawa amagwiritsidwa ntchito powomba: Chitsulo, Chitsulo chosapanga dzimbiri, Mkuwa, Mkuwa, Nickel ndi Mkuwa, zitsulo zonse zachitsulo ndi zopanda chitsulo (kupatula aluminium ndi manganese). Kukhalapo kwa siliva wochuluka kumapangitsa kuti zitheke kupanga ma alloys okhala ndi kutentha kocheperako. Pali mitundu iwiri ya ogulitsa siliva: Ternary solders (wopangidwa ndi Silver, Copper ndi Zinc) ndi quaternary solders (wopangidwa ndi Silver, Copper, Zinc ndi Tin).

Zogulitsa zasiliva zimalimbikitsidwa panjira zonse zogulitsira. Ndodo zophimbidwa ndi BRAZARGENT ® ndi ndodo za TBW zimalola kugwiritsa ntchito solder mosavuta, popanda kuyang'anira kulowetsa kwa flux pamanja.

Mawonekedwe:
  • Bare baguettes + kuvula flux (phala ndi ufa)
  • Ma baguette ophimbidwa
  • Ndodo za TBW (Tubular Brazing Wire)
  • Preforms (mphete, billets)

Zida za Aluminium

Ma aloyi athu (Aluminium-Silicon ndi Zinc-Aluminiyamu) amaphimba ntchito zambiri zopangira zida za aluminiyamu wina ndi mnzake kapena ndi zida zina. Zomwe zidapangidwa kuti zichepetse komanso kukhathamiritsa kugwiritsa ntchito mitundu iyi ya solder (TBW (mawaya achubu) ndi matekinoloje a TBM (mawaya ophatikizika) amapereka kukhazikika, kubwereza komanso kupindula panthawi yogulitsa.

  • Bare baguettes + kuvula flux (phala ndi ufa)
  • Ma baguette ophimbidwa
  • Ndodo za TBW (Tubular Brazing Wire)
  • Nkhombo za TBM (Waya Wophatikizika Wa Brazing)
  • Preforms (mphete)

Fluxes strippers

Flux iyenera kusungunula ma oxide otsala, kuchuluka kwake kwamadzimadzi kumawongolera woyendetsa poyambitsa zitsulo zodzaza. Kuyenda bwino kumachedwetsa kusungunuka kwa zinthu. Chitsulocho chikasungunuka, gawo lina la flux lidzasungunuka ndipo gawo lina lipanga zotsalira. Pambuyo pakuwotcha, mbalizo zimamasulidwa ku flux (zotsalira) mwa kutsuka ndi madzi otentha kapena makina.

Kusankha kwakukulu kwazinthu zopangira, mitundu yokutira ndi kuyika pamtundu wanu zitha kupangidwa.

Kuletsa kwa Cadmium: Regulation (EU) n ° 494/2011 ya 20/05/2011

Kuyambira pa Disembala 10, 2011, kugulitsa ndi kugwiritsa ntchito ma solders amphamvu okhala ndi cadmium (Cd) okhala ndi ndende yayikulu kuposa kapena yofanana ndi 0.01% polemera, anali oletsedwa.

Ma alloys ena omwe ali ndi Cadmium akupezeka mumtundu wathu wa brazing.
Osazengereza kulumikizana ndi akatswiri athu kuti mumve zambiri pankhaniyi.
