Microstructure:Muaj cov kab Cu₃P theem, txhim kho kev ua haujlwm kub.
Welding yam ntxwv:Tsis muaj kev pheej hmoo ntawm hydrogen embrittlement thaum lub sij hawm vuam, superior rau cov electrolytic tooj liab tsis tu ncua.
Nqi Positioning:Poob ntawm oxygen- tooj liab dawb thiab tsis tu ncua electrolytic tooj liab.
Kub ua haujlwm:
Kub dov cracking susceptibility txo los ntawm kwv yees li 60% piv rau li niaj zaus electrolytic tooj liab.
Haum kub ua hauj lwm kub ntau yam expands mus rau 650-850 degree.
Kub dov hla kev txo qis tuaj yeem tshaj 50%.
Welding Performance:
Cov khoom zoo heev brazing, nrog fluidity txhim kho li ntawm 30% piv rau cov tooj liab li niaj zaus.
Muaj peev xwm ntawm ntau txoj kev vuam: oxyacetylene, arc, TIG, thiab lwm yam.
Tshwj xeeb yog tsim rau siab - zaus induction brazing txheej txheem.
Corrosion Resistance Yam ntxwv:
Siab -kub oxidation kuj zoo dua li oxygen- tooj liab dawb (oxidation tus nqi txo los ntawm 25% ntawm 800℃).
Kev txhim kho tseem ceeb hauv kev tiv thaiv kev ntxhov siab corrosion cracking.
Zoo stability nyob rau hauv sulfur- muaj ib puag ncig.
Tej thaj chaw thov:
Thaum tshav kub kub Exchange Systems:
Condenser raj rau cov khoom siv tub yees (phab ntsa thickness 0.3-1.2mm)
Cov khoom siv tseem ceeb rau automotive radiators
Evaporator raj rau cov twj tso kua mis kub
Piping rau hnub ci thermal collectors
Kev Siv Dej Siv Hauv Tsev:
Cov kav dej tuaj yeem siv tau (ua raws li NSF / ANSI 61 tus qauv)
Gas muab cov kav dej
Cov kav dej faib rau cov cua sov hauv qab
Piping rau hluav taws sprinkler systems
Tshwj xeeb Industrial Applications:
Cov khoom siv hauv ob sab phlu rau cov khoom siv tshuaj
Fermentation tanks rau kev lag luam brewing
Piping systems rau cov khoom siv tshuaj
Heat exchanger tubes rau seawater desalination nroj tsuag
Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm technical:
Cov txheej txheem txias txias:
Annealed hardness HV55-75, haum rau kev sib sib zog nqus nqus (qhov siab tshaj plaws kos duab tuaj yeem ncav cuag 2.1).
Intermediate annealing kub 450-600 degree, tuav lub sij hawm 1-2 teev ib hli tuab.
Cov txheej txheem vuam:
Pom zoo kom siv nyiaj -cov kabmob brazing muab tub lim (BAg-8 series).
Kev pom zoo tiv thaiv roj: 95% N₂ + 5% H₂ sib tov.
Rau pob tw vuam ntawm cov hlab, qhov sib txawv ntawm 0.1-0.3mm yog pom zoo.
Kev kho deg:
Tshuaj polishing tuaj yeem siv phosphoric -nitric acid systems.
Kev kho mob Passivation yog pom zoo nrog benzotriazole derivative daws.
Acid pickling activation (xws li, 10% H₂SO₄ kua) yuav tsum tau ua ntej electroplating.
