Keeb Kwm Kev Siv
Tooj liab yog ib qho ntawm cov txheej txheem qub tshaj plaws paub rau tib neeg; Cov kws tshaj lij keeb kwm thiab cov neeg paub keeb kwm ntseeg tias tsuas yog siv hlau siv ua ntej tooj liab tau kub thiab cov ore.
Tooj liab hlau tau siv txij li thaum aptly hu ua tooj liab lub hnub nyoog tooj liab. Qee qhov qub tshaj plaws tooj liab cuav, xws li lub pendant los ntawm sab qaum teb Iraq, hnub tim rau ib puag ncig 9000 BC. Nruab nrab ntawm 6000 thiab 3000 BC, Neeg Asmeskas haiv neeg nyob ntawm Michigan thiab Wisconsin txias-cuab yeej txias-cov cuab yeej thiab khoom zoo nkauj. Hauv cov neeg ua yeeb yam, cov neeg Greeks thiab Loos siv tooj liab thiabtooj liab alloysnyiamtoojTxhawm rau ua txhua yam, xws li lub tsev vov tsev, npib, cov hniav nyiaj hniav kub, duab puab thiab ntaj thiab hmuv. Tooj liab tseem ceeb hauv Ancient Is Nrias teb, Israel, Turkey, Iran thiab Egypt. Cov neeg Iziv tshwj xeeb yog ntse nrog lawv siv cov khoom siv hlau; Lawv tau siv nws los ua cov khoom xws li cov tshuab ua noj, tais diav, hoes, cov tawv nqaij, saws, cov iav, tsom iav thiab chais. Lawv txawm siv tooj liab hlau sib txuas los tsim cov pleev pleev.
Thaum ntxov lub sijhawm tshiab, tib neeg pib mining tooj liab ore. Ib qho ntawm cov loj tshaj plaws tooj liab manes hauv hav zoov yog tus tooj liab lub roob, ib qho uas kuv tau lees paub txog kev ua haujlwm ntawm xyoo 19th2. Thaum lub sijhawm ntawd, tooj liab tau siv ntau yam los ua riam phom thiab ua daim duab puab. Nyob rau hauv lub xyoo pua 18th, nkoj tsim qauv tooj liab thiab tooj liab plating los tiv thaiv underwater hauv qab nkoj hulls. Xyoo 1876, thawj niaj hnub no electroplating cog, norddeutsche affinerie, qhib nws lub qhov rooj hauv hamburg.
Nyob rau xyoo 1800s dhau los ntawm 1990s, tooj liab tau mined ntau thoob ntiaj teb, tshwj xeeb tshaj yog nyob hauv Asmeskas. Niaj hnub no, ntau ntawm cov mines ntawd, uas tau ua rau muaj kuab paug, tau kaw. Txawm li cas los xij, tus tooj liab tau nthuav dav tau suav cov ntawv thov kev suav suav, los ntawm cov hniav nyiaj hniav kub rau kev tawm tsam los tiv thaiv biofouling.
Lub USES rau tooj liab puas tau nthuav dav, tshwj xeeb tshaj yog tsis ntev los no hauv computer tsim, electronics thiab kev sib tw lag luam. Cov xov tooj uas twb muaj lawm yog tsim ntawm cov xov tooj tooj liab uas muaj cov khoos phis tawj tsis zoo rau kev sib txuas lus fiber ntau rau kev sib txuas lus thiab kev sib txuas lus. Tsis tas li, txhuas lub computer chips tau hloov los ntawm tooj liab tej daim tawv vim yog tooj liab tus conductivity zoo dua. Qhov no ua rau cov neeg soj xyuas channel ntev thiab dav yuav tau txo ntau heev, uas txhais tau tias kev ua haujlwm nrawm dua. Thaum kawg, tooj liab yog ib tus neeg ua si loj nyob rau hauv lub up-thiab-dhau hluav taws tsheb lag luam.
