Oxygen-Free Copper
Liab tooj liab muaj cov hluav taws xob zoo thiab thermal conductivity, zoo heev plasticity, yooj yim rau kub thiab txias siab ua, thiab yog dav siv nyob rau hauv lub tsim ntawm hluav taws xob nyob ntawm tej, cables, hluav taws xob txhuam, hluav taws xob spark tooj liab thiab lwm yam khoom uas yuav tsum tau zoo hluav taws xob conductivity.
Feem ntau siv tooj liab alloys tau muab faib ua peb pawg: tooj dag, tooj liab, thiab cupronickel. Ntshiab tooj liab yog xim liab-liab hlau, feem ntau hu ua "liab tooj liab", "liab tooj liab" los yog "liab tooj liab". Liab tooj liab lossis liab tooj liab yog lub npe rau nws cov xim liab-liab. Nws tsis yog cov tooj liab dawb huv, thiab qee zaum me me ntawm deoxidizing cov ntsiab lus lossis lwm cov ntsiab lus ntxiv los txhim kho cov khoom siv thiab kev ua haujlwm.
Yog li ntawd, liab tooj liab kuj tau muab faib ua tooj liab alloy. Tuam Tshoj cov khoom siv tooj liab tuaj yeem muab faib ua: tooj liab zoo tib yam (T1, T2, T3, T4), oxygen-dawb tooj liab (TU1, TU2 thiab high-purity, nqus pa tsis muaj tooj liab), deoxidized tooj liab (TUP, TUMn), ntxiv Ib qho me me ntawm alloy Plaub hom tshwj xeeb tooj liab (arsenic tooj liab, tellurium tooj liab, nyiaj tooj liab). Cov hluav taws xob conductivity thiab thermal conductivity ntawm tooj liab yog thib ob tsuas yog nyiaj, thiab nws yog dav siv los ua cov khoom siv hluav taws xob thiab thermal. Liab tooj liab muaj corrosion kuj zoo nyob rau hauv cov huab cua, dej hiav txwv, ib co non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, ntsev tov thiab ntau yam organic acids (acetic acid, citric acid)
Tooj liab muaj ntau yam kev siv ntau dua li cov hlau ntshiab. Txhua xyoo, 50% ntawm tooj liab yog electrolytically purified rau hauv ntshiab tooj liab, uas yog siv nyob rau hauv cov hluav taws xob kev lag luam. Cov tooj liab liab tau hais los ntawm no tiag tiag yuav tsum yog cov ntshiab heev, nrog cov ntsiab lus tooj liab ntau dua 99.95%. Ib qho me me ntawm impurities, tshwj xeeb tshaj yog phosphorus, arsenic, txhuas, thiab lwm yam, yuav txo tau qhov conductivity ntawm tooj liab. Feem ntau yog siv rau hauv cov khoom siv hluav taws xob, chav siv hluav taws xob thiab kev lag luam tshuaj lom neeg, tshwj xeeb tshaj yog cov khoom siv hluav taws xob hluav taws xob hauv hluav taws xob, cov tooj liab rau cov hlau thaiv, cua cushions, busbar terminals; electromagnetic keyboards, cwj mem tuav, thiab lub ru tsev boards. Kev lag luam pwm kev lag luam siv ntau qhov no, yog li Ua rau tus nqi siab.
Nws yog siv los ua cov khoom siv hluav taws xob xws li cov tshuab hluav taws xob, tsheb npav, cables, switchgear, transformers, heat exchangers, pipelines, flat plate collectors of solar heating devices and other heat-conducting equipment. Oxygen nyob rau hauv tooj liab (ib qho me me ntawm cov pa oxygen yog yooj yim sib xyaw thaum lub sij hawm tooj liab smelting) muaj kev cuam tshuam zoo rau kev ua haujlwm, thiab tooj liab siv hauv kev lag luam hluav taws xob feem ntau yuav tsum yog tooj liab tsis muaj oxygen. Tsis tas li ntawd, impurities xws li txhuas, antimony, thiab bismuth yuav ua rau cov tooj liab muaju tsis tuaj yeem sib txuas ua ke, ua rau thermal embrittlement, thiab tseem yuav cuam tshuam rau kev ua cov tooj liab ntshiab. Cov tooj liab ntshiab no feem ntau ua kom zoo dua los ntawm electrolysis: tooj liab tsis huv (uas yog, blister tooj liab) yog siv los ua cov anode, cov tooj liab ntshiab yog siv los ua cathode, thiab tooj liab sulfate tov yog siv los ua cov electrolyte. Thaum qhov tam sim no dhau lawm, cov tooj liab tsis huv ntawm lub anode maj mam yaj, thiab cov tooj liab ntshiab maj mam precipitates ntawm cathode. Cov tooj liab refined nyob rau hauv txoj kev no muaj ib tug purity ntawm 99.99%.
Nws kuj tseem siv rau hauv kev tsim lub cev muaj zog luv luv-circuit rings, electromagnetic cua sov inductors, thiab cov khoom siv hluav taws xob muaj zog, cov khoom siv hluav taws xob, thiab lwm yam.
Nws kuj tau siv rau rooj tog thiab kho kom zoo nkauj xws li qhov rooj, qhov rais, thiab armrests.
High purity, zoo qauv, tsis tshua muaj oxygen cov ntsiab lus. Tsis muaj pores, trachoma, looseness, zoo heev hluav taws xob conductivity, siab precision ntawm qhov chaw ntawm lub electro-eroded pwm, tom qab kev kho cua sov, lub electrode yog tsis-directional, haum rau precision ua, thiab muaj zoo thermal conductivity, processability, ductility, thiab corrosion kuj Tos
