Taw qhia: Ob lub siab-Conductivity tooj liab
Tooj liab rau hluav taws xob thiab thermal kev pab cuam yog muag nyob rau hauv ob peb qib uas zoo tib yam tab sis coj txawv txawv nyob rau hauv fabrication thiab kev pab cuam. Qhov ob feem ntau yog ETP tooj liab thiab EC-hom high-purity tooj liab. Ob leeg ua tau zoo heev hluav taws xob conductivity, tab sis lawv yog tsim txawv thiab muaj sib txawv zog thiab tsis muaj zog. Qhov kev txiav txim siab sib txawv yog oxygen: ntau npaum li cas tam sim no, thiab nws ua li cas rau cov hlau thaum lub sij hawm vuam, brazing, thiab raug rau txo cov cua.
ETP Copper (C11000) yog dab tsi?
Electrolytic tawv pitch (ETP) tooj liab, UNS C11000, yog refined electrolytically thiab ces cam khwb cia nrog ib tug tswj tus nqi ntawm cov pa, feem ntau yog 0.02-0.05%, siv cov txheej txheem nyuaj-pitch. Cov pa oxygen tshem tawm cov impurities xws li phosphorus, sulfur, thiab hlau thaum lub sij hawm melting thiab tawm ib tug me me dispersion ntawm cuprous oxide (Cu2O) hais nyob rau hauv cov hlau. ETP tooj liab yog tsawg kawg yog 99.90% ntshiab thiab yog cov khoom siv hluav taws xob ntau tshaj plaws, pom nyob rau hauv cov hluav taws xob cables, busbars, switchgear, connectors, kav dej, radiators, thiab tshav kub exchangers. Nws qhov kev txwv tseem ceeb tshwm sim thaum nws tau ua kom sov hauv qhov chaw txo qis: hydrogen diffuses rau hauv cov hlau thiab reacts nrog Cu2O hais los ua chav, uas tsim cov voids sab hauv thiab tawg, ib hom tsis ua hauj lwm hu ua hydrogen embrittlement.
Dab tsi yog EC-Type High-Purity Copper (C10200)?
EC-hom tooj liab yog hais txog high-conductivity tooj liab nrog ultra-low oxygen, tsim los ntawm melting nyob rau hauv lub tshuab nqus tsev los yog inert gas kom cov pa cov ntsiab lus nyob rau hauv los yog qis dua li ntawm 0.001%. Hauv UNS cov ntsiab lus qhov no feem ntau yog C10200, tsis muaj pa oxygen tooj liab tsawg kawg 99.95% ntshiab nrog qhov tseem ceeb tsis muaj Cu2O. Tshem tawm cov pa oxygen tshem tawm qhov kev pheej hmoo ntawm hydrogen embrittlement, ua kom qis qis, thiab khaws cov conductivity thiab ductility los ntawm vuam thiab brazing. Cov yam ntxwv no ua rau EC-hom tooj liab qhov tshwj xeeb ntawm kev xaiv rau high-frequency cables, microwave Cheebtsam, lub tshuab nqus tsev, semiconductor manufacturing khoom, thiab aerospace thiab tiv thaiv thaiv, nrog rau kev pab nyob rau hauv hydrogen-nplua nuj ib puag ncig xws li refineries thiab tshuaj nroj tsuag.
Qhov tseem ceeb sib txawv ntawm ib saib
ETP Copper (C11000): oxygen 0.02-0.05%, purity yam tsawg kawg nkaus 99.90%, muaj cuprous oxide particles, raug rau hydrogen embrittlement thaum rhuab nyob rau hauv txo cua sov, tsis tshua muaj nqi, yooj yim rau kev tsim thiab koom, zoo tagnrho rau hluav taws xob, kav dej, thiab tshav kub hloov dej. EC / Oxygen-free Copper (C10200): oxygen 0.001% lossis tsawg dua, purity yam tsawg kawg nkaus 99.95%, tsis muaj oxide tseem ceeb, tiv thaiv hydrogen embrittlement, qis outgassing, tus nqi siab dua, nyiam rau cov khoom siv hluav taws xob muaj kev ntseeg siab, lub tshuab nqus tsev, thiab kev siv aerospace. Ob qib ua hluav taws xob thiab cua sov ntawm qhov tseem ceeb tib theem, yog li qhov kev txiav txim siab yog tsav los ntawm ib puag ncig, kev tsim khoom, thiab kev ntseeg siab es tsis yog conductivity ib leeg.
Daim ntawv qhia kev
Xaiv ETP tooj liab rau kev ua haujlwm dav dav uas cov nqi tseem ceeb thiab cov hlau yuav tsis raug welded los yog raug kub txo cua sov: fais fab cables, busbars, switchgear, hluav taws xob connectors, kav dej, radiators, thiab cua txias coils. Xaiv EC-hom oxygen-dawb tooj liab thaum daim ntawv thov xav tau ultra-siab kev ntseeg tau: high-frequency thiab microwave Cheebtsam, superconducting hlau nplaum systems, MRI thiab precision instruments, nqus tsev vacuum, semiconductor fabrication cov cuab yeej, hydrogen kev pab cuam, thiab aerospace los yog tiv thaiv thaiv. Thaum tsis ntseeg txog vuam, brazing, los yog ib puag ncig uas muaj hydrogen, oxygen-dawb tooj liab yog qhov kev nyab xeeb dua, txawm tias nws raug nqi ntau dua ib kilogram.
FAQ
ETP sawv cev rau dab tsi?
ETP sawv cev rau electrolytic tawv pitch. Nws yog qib hluav taws xob ntau tshaj plaws, ua los ntawm electrolytic refining ua raws li cov txheej txheem nyuaj-pitch melting uas tswj cov ntsiab lus oxygen ntawm kwv yees li 0.02-0.05%.
Puas yog EC tooj liab zoo ib yam li tooj liab tsis muaj oxygen?
Hauv kev xyaum, yog rau cov ntsiab lus no: EC-hom tooj liab tau muab cov ntsiab lus oxygen ntawm lossis qis dua li ntawm 0.001%, uas yog lub ntsiab lus ntawm cov qib tsis muaj oxygen xws li UNS C10200. Cov ntsiab lus sib txawv ntawm cov qauv, yog li cov neeg yuav khoom yuav tsum lees paub UNS tus lej thiab cov pa oxygen txwv ntawm daim ntawv pov thawj.
Vim li cas oxygen tseem ceeb hauv tooj liab?
Oxygen tsim cov khob oxide uas ntxiv dag zog rau cov hlau me ntsis tab sis ua rau nws nkig yog tias hydrogen nkag mus rau qhov kub siab. Hauv kev txo cov huab cua, hydrogen reacts nrog oxide los tsim cov hnab ris hauv cov hlau, ua rau tawg hu ua hydrogen embrittlement.
Cov qib tooj liab twg muaj kev ua tau zoo dua, ETP lossis EC?
Ob leeg ncav cuag li 100% IACS nyob rau hauv cov mob annealed. ETP thiab oxygen-dawb tooj liab yog qhov tseem ceeb sib npaug hauv hluav taws xob thiab thermal conductivity, yog li kev xaiv ntawm lawv yog nyob ntawm fabrication, ib puag ncig, thiab kev ntseeg siab, tsis yog conductivity.
ETP tooj liab puas tuaj yeem welded?
Yog, tab sis nrog kev saib xyuas. Vuam thiab brazing ntawm ETP tooj liab yog niaj hnub nyob rau hauv huab cua, tab sis cua sov nws nyob rau hauv ib tug hydrogen-muaj los yog txo cov huab cua txaus ntshai hydrogen embrittlement. Rau welded Cheebtsam uas yuav pom tom qab txo cov kev pab cuam, oxygen-dawb tooj liab raug pom zoo.
Vim li cas tooj liab tsis muaj oxygen siv hauv cov khoom siv nqus tsev?
Oxygen-dawb tooj liab tsis tshua muaj outgassing thiab tsis muaj oxide hais los tso gases, yog li nws ua kom lub tshuab nqus tsev huv si thiab ruaj khov. Qhov no yog vim li cas nws tshwm sim hauv lub tshuab nqus tsev, cov cuab yeej semiconductor, thiab cov khoom siv hluav taws xob ntau zaus.
