10 qhov tseeb nthuav txog tooj liab. Koj paub pes tsawg?
Tooj liab yog cov hlau zoo nkauj thiab muaj txiaj ntsig zoo uas tuaj yeem pom thoob plaws hauv koj lub tsev, ob qho tib si hauv nws daim ntawv ntshiab thiab hauv cov tebchaw. Copper yog lub ntsiab naj npawb 29 ntawm lub rooj zaum thiab nws lub cim yog Cu, uas los ntawm Latin lo lus cuprum. Lub npe txhais tau tias "los ntawm cov kob ntawm Cyprus," ib kob uas paub txog nws cov tooj liab mines. Nov yog 10 qhov tseeb nthuav txog tooj liab uas yuav tshuab koj lub siab!
1. tooj liab yog ib qho ntawm cov hlau qub tshaj plaws uas tib neeg siv hauv ntiaj teb
Nws keeb kwm ntawm kev siv hnub rov qab ntau dua 10, 000 xyoo. Cov khoom siv tooj liab ntxov tshaj plaws yog ua los ntawm cov tooj liab ntshiab, tab sis tom qab ntawd tib neeg pom tias kev sib xyaw tooj liab nrog lwm cov hlau tuaj yeem ua rau cov alloys nyuaj, xws li tooj liab (ib qho hlau ntawm tooj liab thiab tin) thiab tooj dag (ib qho hlau ntawm tooj liab thiab zinc).
2. Tooj liab muaj xim liab tshwj xeeb
Ntshiab tooj liab yog xim liab-xim av, thiab tooj liab yog tib yam hlau uas muaj xim no. Lwm cov hlau uas tsis yog nyiaj yog kub, uas muaj xim daj. Yog tias tooj liab thiab kub sib xyaw ua ke, lawv tuaj yeem ua rau kub kub lossis kub kub, uas yog nrov hauv cov hniav nyiaj hniav kub thiab cov khoom dai.
3. tooj liab yog ib qho tseem ceeb heev ntawm kab
Tooj liab muaj ntau yam txiaj ntsig rau tib neeg kev noj qab haus huv. Tooj liab tuaj yeem txhawb kev tsim cov qe ntshav liab, koom nrog kev loj hlob ntawm cov pob txha thiab cov ntaub so ntswg, tswj cov kev ua haujlwm ntawm lub paj hlwb thiab kev tiv thaiv kab mob, thiab muaj cov tshuaj tiv thaiv antioxidant thiab tiv thaiv kab mob. Tib neeg lub cev yuav tsum tau noj cov tooj liab txhua hnub. Feem ntau hais lus, cov neeg laus xav tau 0.8 mg ntawm tooj liab ib hnub, thiab cov menyuam yaus thiab cov poj niam cev xeeb tub xav tau me ntsis ntxiv. Tooj liab tuaj yeem tau los ntawm ntau yam khoom noj, xws li zaub ntsuab nplooj, nplej, qos yaj ywm thiab taum. Tau kawg, tooj liab yuav tsum tsis txhob noj ntau dhau, txwv tsis pub nws yuav ua rau cov tsos mob xws li mob siab, mob ntshav siab, raws plab, thiab lwm yam.
4. tooj liab yog tus neeg xyuas pib zoo heev
Tooj liab tuaj yeem ua tau zoo tam sim no thiab cua sov. Tooj tooj hluav taws xob conductivity yog thib ob tsuas yog nyiaj, qhov thib ob siab tshaj plaws ntawm tag nrho cov hlau, thiab tooj liab yog pheej yig dua li nyiaj, yog li tooj liab yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov khoom siv hluav taws xob xws li xov hlau, cables, thiab Circuit Court boards. Tooj kuj tseem muaj cov thermal conductivity siab, uas yog qhov thib ob siab tshaj plaws ntawm tag nrho cov hlau, thib ob tsuas yog nyiaj. Qhov no txhais tau hais tias tooj liab tuaj yeem sai sai dissipate tshav kub thiab tiv thaiv overheating. tooj liab kuj tseem siv tau los ua cov tshuab hluav taws xob, cov khoom siv hluav taws xob, cov lauj kaub thiab cov lauj kaub thiab lwm yam khoom siv uas yuav tsum tau hloov cov cua sov kom zoo.
5. Copper yog ib qho tshuaj tua kab mob ntuj
Tooj liab tuaj yeem tua tau ntau yam kab mob, kab mob thiab fungi, tiv thaiv kab mob thiab kis kab mob. Cov tshuaj tiv thaiv kab mob ntawm tooj liab yog txhawm rau rhuav tshem cov cell membrane ntawm cov kab mob, cuam tshuam nrog lawv cov metabolism thiab cov khoom siv caj ces, thiab ua rau lawv poob lawv txoj haujlwm thiab muaj peev xwm tsim tawm. Tooj liab kuj tseem tuaj yeem ua rau qee yam tshuaj lom, xws li chlorine thiab carbon monoxide. Yog li ntawd, tooj liab muaj ntau yam kev siv hauv kev kho mob, kev tu cev, kev ua zaub mov, thiab lwm yam, xws li lub qhov rooj tooj liab, faucets, cov cuab yeej phais, cov thawv ntim khoom noj, thiab lwm yam, uas tuaj yeem txo qhov kev loj hlob thiab kev sib kis ntawm cov kab mob.
6. Tooj yog ib qho hlau ruaj khov heev
Tooj liab tuaj yeem tswj hwm nws qhov kev ua tau zoo thiab tsim nyob rau hauv ntau qhov chaw huab cua. Tooj liab tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj melting lossis embrittlement. Lub melting point ntawm tooj liab yog 1084.62 degrees Celsius, uas yog siab tshaj plaws ntawm tag nrho cov hlau. Tooj liab kuj muaj qhov ua tau zoo ntawm qhov kub thiab txias. Nws tseem tuaj yeem tuav tau zoo conductivity thiab ductility ntawm qhov kub thiab txias ze rau qhov tsis muaj tseeb. Tooj liab kuj tuaj yeem tiv thaiv corrosion los ntawm ntau yam tshuaj, xws li dej ntsev, kua qaub, alkali, thiab lwm yam. Qhov no tso cai rau tooj liab siv los tsim cov nkoj, submersibles, spacecraft thiab lwm yam khoom siv uas yuav tsum tau ua haujlwm nyob rau hauv hnyav hnyav.
7. Cov tooj liab tuaj yeem ua rau ntau yam xim thiab ntau hom
Cov xim ntawm tooj liab nyob ntawm nws cov purity thiab degree ntawm oxidation, xws li xim av liab mus rau txiv kab ntxwv thiab ntsuab. Tooj liab kuj tuaj yeem tsim ntau yam sib txawv nrog rau lwm cov ntsiab lus, xws li tooj liab sulfide, tooj liab oxide, tooj liab carbonate, thiab lwm yam, thiab cov khoom sib txuas no muaj xim sib txawv, xws li xiav, dub, liab, dawb, thiab lwm yam. Cov tooj liab kuj tuaj yeem tsim tau ntau yam alloys. nrog rau lwm yam hlau, xws li tooj liab, tooj dag, dawb tooj liab, tooj liab, thiab lwm yam, thiab cov khoom thiab kev siv ntawm cov alloys no kuj txawv. Daim ntawv ntawm tooj liab kuj tuaj yeem hloov pauv los ntawm kev ua thiab kev kho mob, xws li kev kos duab hlau, forging, dov, electroplating, thiab lwm yam, uas tuaj yeem muab cov tooj liab sib txawv thiab cov yam ntxwv.
8. Copper yog ib qho zoo heev rau ib puag ncig
Tooj liab tuaj yeem rov ua dua tshiab yam tsis tau poob nws qhov zoo thiab tus nqi. Tooj liab muaj tus nqi rov ua dua. Nws tau kwv yees tias 80% ntawm lub ntiaj teb tooj liab tseem nyob hauv kev ncig es tsis txhob muab pov tseg lossis tso tseg. Cov txheej txheem rov ua tooj liab kuj yooj yim. Koj tsuas yog yuav tsum tau yaj cov khoom seem tooj liab thiab tshem tawm impurities. Koj tsuas yog yuav tsum tau yaj cov khoom seem tooj liab thiab tshem tawm cov impurities kom tau cov kua tooj liab ntshiab, thiab tom qab ntawd los ntawm kev casting, koj tuaj yeem ua cov khoom tooj liab tshiab. Recycling tooj liab tsis tsuas yog txuag cov peev txheej thiab txo cov nqi thiab kev ua qias tuaj ntawm cov mining thiab kev ua haujlwm, tab sis kuj tseem tuav cov khoom zoo thiab tus nqi ntawm tooj liab, coj cov txiaj ntsig zoo rau kev lag luam thiab tib neeg.
9. Tooj Oxidation
Tooj liab oxidizes nyob rau hauv cov huab cua ntub los tsim ib txheej ntawm ntsuab tooj liab xeb, kuj hu ua verdigris. Cov oxide no tiv thaiv cov tooj liab los ntawm kev xeb ntxiv thiab tseem muaj qhov zoo nkauj tshwj xeeb. Koj puas paub tias tus Pej thuam ntawm Kev ywj pheej hauv Tebchaws Meskas muaj cov tsos ntsuab vim yog tooj liab oxidation?
10. Copper ranks thib peb hauv industrial siv
Tooj tooj yog thib peb hauv kev siv, thib ob tsuas yog hlau thiab txhuas. Tooj liab yog siv nyob rau hauv cov xov hlau (siv rau 60% ntawm tag nrho cov tooj liab siv), kav, hluav taws xob, kev tsim kho, cookware, npib thiab lwm yam khoom.
