Qhov txawv ntawm tooj dag, tooj liab, bronze thiab dawb tooj liab yog dab tsi?
Qhov sib txawv ntawm tooj dag, tooj liab, bronze thiab dawb tooj liab yog raws li nram no:
1. Cov xim sib txawv. Cov xim ntawm tooj dag yog daj, xim liab tooj liab yog ntshav-liab, xim ntawm bronze yog xiav, thiab xim ntawm dawb tooj liab yog nyiaj-dawb.
2. Cov tshuaj lom neeg sib txawv.
Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Brass uas muaj tooj liab thiab zinc hu ua tooj dag zoo tib yam. Yog tias nws muaj ntau tshaj ob lub ntsiab lus, feem ntau ntxiv cov ntsiab lus xws li txhuas, tin, aluminium, thiab lwm yam. Ntau yam alloys hu ua tooj dag tshwj xeeb.
Liab tooj liab yog ib hom tooj liab ntshiab. Feem ntau nws tuaj yeem suav hais tias yog tooj liab ntshiab, tab sis nws tsis tas yuav yog tooj liab ntshiab. Qee lub sij hawm me me ntawm deoxidizing cov ntsiab lus lossis lwm cov ntsiab lus tau ntxiv los txhim kho cov khoom siv thiab kev ua tau zoo, yog li nws kuj tau muab faib ua tooj liab alloy.
Bronze yog ib qho alloy uas tin lossis txhuas ntxiv rau cov tooj liab ntshiab (liab tooj liab).
Dawb tooj liab yog tooj liab-raws li alloy nrog nickel ua lub ntsiab ntxiv. Cov tooj liab-nickel binary alloy yog hu ua cupronickel zoo tib yam; cupronickel alloy nrog cov ntsiab lus xws li manganese, hlau, zinc, txhuas thiab lwm yam hu ua complex cupronickel.
3. Cov kev siv sib txawv.
Brass muaj zog hnav tsis kam thiab feem ntau yog siv los tsim cov li qub, cov kav dej, txuas cov kav dej rau sab hauv thiab sab nraud cua txias thiab radiators.
Cov hluav taws xob conductivity thiab thermal conductivity ntawm tooj liab liab yog qhov thib ob tsuas yog nyiaj, thiab nws tau siv dav hauv kev ua cov khoom siv hluav taws xob thiab thermal conductive. Liab tooj liab muaj corrosion kuj zoo nyob rau hauv cov huab cua, dej hiav txwv, tej yam uas tsis yog-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, ntsev tov thiab ntau yam organic acids (acetic acid, citric acid).
Bronze muaj cov yam ntxwv ntawm qhov qis melting point, siab hardness, muaj zog plasticity, hnav tsis kam, corrosion kuj, thiab ci xim. Nws yog tsim rau casting ntau yam khoom siv, mechanical qhov chaw, bearings, zog, thiab lwm yam.
Piv nrog rau lwm cov tooj liab alloys, tooj liab dawb muaj cov khoom zoo heev thiab lub cev. Nws muaj ductility zoo, siab hardness, zoo nkauj xim, corrosion kuj, thiab sib sib zog nqus nqus cov khoom. Nws yog dav siv hauv nkoj tsim, kev lag luam petrochemical, khoom siv hluav taws xob, khoom siv, khoom siv kho mob, thiab khoom siv txhua hnub. , handicrafts thiab lwm yam teb, thiab kuj yog ib qho tseem ceeb resistor thiab thermocouple alloy.
Lub ntiaj teb cov peev txheej tooj liab kuj muaj ntau. Tooj liab tsis yooj yim rau rho tawm los ntawm nws cov ore, tab sis mineable deposits kuj tsis tshua muaj. Lub ntiaj teb cov pov thawj tooj liab yog kwv yees li 350 txog 570 lab tons, ntawm cov porphyry tooj liab tso nyiaj rau kwv yees li 76% ntawm tag nrho. Nyob rau hauv cov nqe lus ntawm lub regional faib, muaj tsib cheeb tsam nrog cov richest tooj liab reserves nyob rau hauv lub ntiaj teb no:
Teb chaws Africa: Congo Luylu (Kolwezi), Hitulu, Zambia Luanshya thiab Baliba, Mufulira, Nchanga TLP, Nkana (Lokana).
Asia: Tuam Tshoj Nyiaj (Jinchuan) / Gansu, Shandong / Yanggu Xiangguang Copper Daye, Guixi, Huludao, Jinchang, Shanghai, Tianjin, Yunnan, India Birla Copper (Dahai), Tuticorin, Salcesme, Iran, Besshi / Ehime, Nyiv (Toyo Smelter ). Kosaka (Akita), Naoshima (Kagawa), Onahama (Fukushima), Saga Seki (Oita), Tamano (Okayama), Kazakhstan Balkashmys, Jezkazgan Smelter, Onsan, Kaus Lim Qab Teb Smelter I, Wenshan Smelter II, Philippines Isabel / Wright (Philippine Smelting thiab Refining Association), Uzbekistan Almarek Smelter.
Teb chaws Europe: Brickslag, Austria, Belse, Belgium; Hoboken, UM Pierdorp, Finland, Harjavalta, Lub teb chaws Yelemees, Hamburg, Herterstedt, Lunen 170, Potemagra, Ltalis, Gwogu, Poland Gov I, Głogów II, Legnica smelting cog, Zlatna smelting nroj tsuag hauv Romania, Kirovgrad (Karata), Russia, Krasnoursk cog, Nadezhkinsky, Norilsk smelting nroj tsuag, Central Uralsk smelting nroj tsuag, Huelva, Spain, Sweden, Walsall, UK, Bor, Yugoslavia.
