Khoom cim npe

Cov yam ntxwv ntawm cov khoom

Lub npe rau nws purplish liab. Nws tsis tas yuav ntshiab tooj liab, tab sis qee zaum me me ntawm cov ntsiab lus deoxidized los yog lwm cov ntsiab lus ntxiv los txhim kho cov khoom siv thiab kev ua tau zoo, yog li nws kuj tau muab faib ua tooj liab alloy. Suav cov khoom siv tooj liab tuaj yeem muab faib ua plaub pawg raws li muaj pes tsawg leeg: tooj liab zoo tib yam (T1, T2, T3, T4), tooj liab tsis muaj oxygen (TU1, TU2 thiab siab purity, nqus pa tsis muaj tooj liab), deoxidized tooj liab (TUP , TUMn), tshwj xeeb tooj liab nrog me me ntawm alloying ntsiab (arsenic tooj liab, tellurium tooj liab, nyiaj tooj liab). Cov hluav taws xob thiab thermal conductivity ntawm tooj liab yog qhov thib ob tsuas yog nyiaj, thiab siv dav siv los ua cov khoom siv hluav taws xob thiab thermally conductive. Tooj liab muaj corrosion kuj zoo nyob rau hauv cov huab cua, dej hiav txwv thiab tej yam uas tsis yog-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, ntsev tov thiab ntau yam organic acids (acetic acid, citric acid), thiab yog siv nyob rau hauv kev lag luam tshuaj. . Tsis tas li ntawd, tooj liab muaj qhov zoo weldability thiab tuaj yeem ua rau ntau yam khoom ua tiav thiab tiav los ntawm kev ua haujlwm txias thiab thermoplastic.

Khoom Qhia

Lub cev muaj zog

Cov kab impurities hauv tooj liab muaj kev cuam tshuam loj rau hluav taws xob thiab thermal conductivity ntawm tooj liab. Ntawm lawv, titanium, phosphorus, hlau, silicon, thiab lwm yam, txo cov hluav taws xob conductivity, thaum cadmium thiab zinc muaj tsawg heev. Oxygen, sulfur, selenium, tellurium thiab lwm yam kev daws teeb meem hauv tooj liab yog qhov me me, tuaj yeem tsim cov nkig sib txuas nrog tooj liab, qhov cuam tshuam ntawm kev cuam tshuam tsis yog qhov tseem ceeb, tab sis tuaj yeem txo cov txheej txheem plasticity. Cov tooj liab zoo tib yam hauv qhov chaw txo qis uas muaj hydrogen lossis carbon monoxide thaum cua sov, hydrogen lossis carbon monoxide yooj yim cuam tshuam nrog cov ciam teb ntawm cuprous oxide (Cu2O), uas ua rau cov dej kub siab lossis cov pa roj carbon dioxide, uas tuaj yeem ua rau tooj liab tawg. . Qhov tshwm sim no feem ntau hu ua tooj liab "hydrogen kab mob". Oxygen yog teeb meem rau lub solderability ntawm tooj liab. Bismuth los yog txhuas thiab tooj liab los tsim cov ntsiab lus melting tsawg eutectic, kom tooj liab ua kub nkig; thiab brittle bismuth yog faib nyob rau hauv lub grain ciam ciam ntawm cov zaj duab xis, thiab ua rau tooj liab ua txias nkig. Phosphorus tuaj yeem txo cov hluav taws xob conductivity ntawm tooj liab, tab sis tuaj yeem txhim kho cov kua dej ntawm tooj liab, txhim kho qhov kev sib txuas. Qhov zoo ntawm cov hlau lead, tellurium, sulfur, thiab lwm yam tuaj yeem txhim kho lub tshuab ua haujlwm. Chav tsev kub tensile lub zog ntawm tooj liab annealed ntawv yog 22-25 kg quab yuam / mm2, elongation yog 45-50%, Brinell hardness (HB) yog 35-45.

Lub thermal conductivity ntawm tooj liab ntshiab yog 386.4 W / (mK).

Hom kev siv

Copper yog siv ntau dua li cov hlau ntshiab, nrog 50% ntawm tooj liab raug electrolytically purified rau tooj liab ntshiab txhua xyoo rau kev siv hauv kev lag luam hluav taws xob. Cov tooj liab hais ntawm no yuav tsum yog cov ntshiab heev, muaj ntau tshaj 99.95% tooj liab siv. Tsawg heev ntawm impurities, tshwj xeeb tshaj yog phosphorus, arsenic thiab txhuas, tuaj yeem txo cov hluav taws xob conductivity ntawm tooj liab zoo heev. Feem ntau yog siv rau hauv kev tsim cov tshuab hluav taws xob, tsheb npav, cables, switchgear, transformers thiab lwm yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, cov kav dej, cov khoom siv hluav taws xob hnub ci xws li cov phaj tiaj tiaj thiab lwm yam khoom siv hluav taws xob. Copper muaj cov pa oxygen (tooj liab refining yog ib qho yooj yim los sib tov me me ntawm cov pa oxygen) ntawm cov khoom siv hluav taws xob zoo, 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, bismuth, thiab lwm yam tuaj yeem ua rau crystallization ntawm tooj liab tsis tuaj yeem ua ke ua ke, ua rau thermal embrittlement, tseem yuav cuam tshuam rau kev ua cov tooj liab ntshiab. Qhov no ntshiab tooj liab feem ntau refined los ntawm electrolysis: impure tooj liab (ie, crude tooj liab) yog siv raws li cov anode, ntshiab tooj liab li cathode, thiab tooj liab sulfate tov raws li cov electrolyte. Thaum qhov tam sim no dhau mus, cov tooj liab tsis huv ntawm lub anode maj mam yaj, thiab cov tooj liab ntshiab maj mam precipitates ntawm cathode. Cov tooj liab li refined yog tau. Lub purity yog mus txog 99.99%.

Tooj liab kuj tseem siv rau hauv kev tsim cov luv luv-circuit rings rau lub tshuab hluav taws xob, hluav taws xob cua sov inductors thiab cov khoom siv hluav taws xob muaj zog, cov davhlau ya nyob twg, thiab lwm yam.

Tooj liab kuj siv rau hauv qhov rooj, qhov rais, tes tuav thiab lwm yam rooj tog thiab kho kom zoo nkauj.

Cov khoom tseem ceeb

Suav cov khoom siv tooj liab tooj liab tuaj yeem muab faib ua plaub pawg los ntawm kev muaj pes tsawg leeg: tooj liab zoo tib yam (T1, T2, T3, T4), tooj liab tsis muaj oxygen (TU1, TU2 thiab siab purity, nqus pa tsis muaj tooj liab), deoxidized tooj liab (TUP , TUMn), tshwj xeeb tooj liab nrog me me ntawm cov ntsiab lus ntxiv (arsenic tooj liab, tellurium tooj liab, nyiaj tooj liab).
