Brazing Silver To Copper Technology Analysis: Qhov zoo, txheej txheem thiab kev lag luam siv

Hauv kev lag luam HVAC (Tsuas Kub, Qhov Cua, thiab Cua Txias) kev lag luam, Copper Bar Silver Contact Attachment yog dav siv rau kev sib txuas hauv cov kav dej hauv tub yees. Nws lub siab airtightness tuaj yeem tswj tau tus nqi xau li ntawm 1 × 10⁻⁹ Pa·m³ / s, tiv thaiv kom tsis txhob tso cov tub yees. Meanwhile, nws zoo heev thermal conductivity ua kom lub efficiency ntawm tshav kub hloov nyob rau hauv lub system. Nyob rau hauv lub automotive sector, qhov tsawg melting point ntawm Resistance Vuam Nyiaj Sib cuag tau raws li qhov yuav tsum tau kev twb kev txuas ntawm precision Cheebtsam. Nws yog feem ntau siv rau vuam cov kav dej thiab cov khoom sib kis, muab kev txhawb nqa rau kev ua haujlwm ruaj khov ntawm cov tub ntxhais hauv tsheb.

Ntau hom Spot Welding Silver Sib cuag sib txawv ntawm lawv cov yam ntxwv thiab daim ntawv thov tsom. Silver-tooj liab-zinc brazing muab tub lim hlau tsis yog- tshuaj lom, ib puag ncig tus phooj ywg, thiab muaj qhov zoo fluidity. Lawv tuaj yeem ua tau raws li cov kev xav tau ntawm ntau qhov chaw, xws li khoom siv hluav taws xob, tub yees, thiab cov khoom siv tiv thaiv tunneling, ua raws li kev lag luam sib txawv ntawm kev tsim ntsuab. Silver-tooj liab-zinc-nickel brazing muab tub lim hlau khav theeb muaj zog corrosion kuj thiab zoo heev - qhov kub thiab txias, txaus siab rau cov kev xav tau rau kev ntseeg siab thiab huab cua tiv thaiv hauv aerospace, cov cuab yeej kho mob, thiab lwm yam. Silver-tooj liab{12}}phosphorus brazing muab tub lim hlau ua kom yooj yim rau cov txheej txheem ua haujlwm nrog lawv tus kheej-brazing muaj peev xwm, ua rau lawv tshwj xeeb muab tub lim hlau rau cov xwm txheej zoo li HVAC thiab cov kav dej hauv tsheb. Silver-tooj liab-titanium brazing muab tub lim hlau muaj zog brazing zog, ua kom muaj kev sib raug zoo ntawm cov ceramics thiab hlau, thiab ua lub luag haujlwm tseem ceeb hauv high{17}}kawg tsim teb xws li silicon carbide modules rau lub zog tshiab tsheb thiab dav hlau.

Kev siv ntawm Brazing Silver mus rau tooj liab txheej txheem yuav tsum muaj kev tswj hwm nruj ntawm cov ntsiab lus tseem ceeb. Raws li qhov chaw ua ntej- kev kho mob yog lub hauv paus ntawm kev ua kom cov vuam zoo. Ua ntej brazing, nws yog ib qho tseem ceeb kom tshem tawm cov roj, oxides, thiab lwm yam kab mob los ntawm tooj liab nto los ntawm kev sib tsoo los yog tshuaj ntxuav, xyuas kom meej tias qhov roughness ntawm qhov chaw ncav cuag Ra tsawg dua los yog sib npaug li 0.8μm. Nyob rau hauv cov nqe lus ntawm cov txheej txheem xaiv, hu rau cov tshuaj tiv thaiv brazing tuaj yeem siv lub ntsiab lus eutectic ntawm 779℃hauv cov nyiaj -tooj liab binary system kom ua tiav qhov kev sib raug zoo ntawm 0.15mm nyiaj solder nplooj ntawv thiab 1.2mm tooj liab nplooj nyob rau hauv siab ntawm 800℃. Nqus electron beam brazing siv defocused electron beam scanning rau cua sov nyob rau hauv lub tshuab nqus tsev ib puag ncig, uas tsis tsuas yog tiv thaiv tooj liab oxidation tab sis kuj tawm tsis muaj solder residue, ua rau nws haum rau vuam scenarios nrog siab huv si. Cov theem tswj tau zoo yuav tsum tau tsom mus rau ob lub ntsiab lus qhia: ua ntej, kev sib koom ua ke lub zog - lub zog tensile ntawm Resistance Spot Welding Silver Contacts tuaj yeem ncav cuag 360-480 MPa; Thib ob, tus nqi xau - kev sib txuas hauv cov kav dej hauv cov tub yees yuav tsum ua kom tau raws li qhov xav tau ntawm airtightness siab ntawm tus nqi xau qis dua 1 × 10⁻⁹ Pa·m³ / s.

Nrog kev loj hlob tsis tu ncua ntawm kev lag luam kev lag luam xav tau cov khoom siv ntsuab thiab ib puag ncig tus phooj ywg, cadmium-dawb thiab txhuas- dawb nyiaj-raws li brazing muab tub lim hlau tau dhau los ua kev tshawb fawb thiab kev loj hlob hotspot. Cov hlau muab tub lim tshiab no uas ua raws li RoHS tus qauv tau maj mam hloov cov cadmium ib txwm muaj- muaj cov hlau muab tub lim hauv cov khoom siv hluav taws xob. Tib lub sijhawm, nyob rau hauv siab -kawg teb xws li photovoltaics, tooj liab hloov technologies xws li nyiaj-coated tooj liab thiab tooj liab plating yog tsis tu ncua. Txawm li cas los xij, qhov hluav taws xob conductivity thiab stability ntawm cov nyiaj nws tus kheej nyob twj ywm irreplaceable, tshwj xeeb tshaj yog nyob rau hauv siab - kub thiab siab - av noo ib puag ncig. Zuag qhia tag nrho, tso siab rau nws qhov kev ua tau zoo tshaj plaws, Projection Welding Silver Contact tseem yog cov khoom siv zoo tshaj plaws rau kev koom nrog tooj liab thiab tooj liab alloys tam sim no, thiab muaj txoj haujlwm tsis tuaj yeem hloov tau, tshwj xeeb tshaj yog nyob rau hauv kev lag luam nrog kev ntseeg siab nruj. Kev txhim kho yav tom ntej ntawm kev lag luam yuav tsom mus rau kev tshawb fawb thiab kev loj hlob ntawm qis-nyiaj- cov ntsiab lus, ib puag ncig tus phooj ywg, thiab siab - lub zog brazing muab tub lim hlau, txhawm rau sib npaug kev ua haujlwm thiab cov nqi xav tau.

Raws li cov ntaub ntawv tseem ceeb saum toj no, suav nrog HVAC, automotive manufacturing, thiab high -kawg cov cuab yeej, nrog rau cov kev sib tw ntawm brazing muab tub lim hlau ib puag ncig thiab kev ua haujlwm siab, peb tau ua tiav ntau yam ntawmBrazing Silver rau tooj liabcov khoom. Cov khoom no muaj qhov ua kom zoo tshaj plaws hauv cov khoom sib piv thiab cov txheej txheem sib xws, tag nrho npog cov kev xav tau ntawm vuam sib txawv. Yog xav paub ntxiv txog cov qauv ntawm cov khoom, cov kev tsis sib xws, thiab cov kev daws teeb meem tsim nyog rau koj cov kev tsim khoom tshwj xeeb, thov xa mus rau cov khoom sib xws hauv qab no.
