Copper: Cov Hlau Ntau Yam
Copper yog ib qho ntawm cov khoom siv ntau yam thiab siv dav hauv ntiaj teb, tau txais txiaj ntsig rau nws qhov tshwj xeeb ua ke ntawm lub cev, tshuaj, thiab cov khoom siv kho tshuab. Paub txog nws cov reddish- txiv kab ntxwv xim thiab siab conductivity, tooj liab tau ua lub luag haujlwm tseem ceeb hauv kev tsim kho, hluav taws xob, thiab kav dej. Nws cov khoom ua rau nws yog ib qho tseem ceeb rau kev tsim cov kav dej tooj liab, raj, thiab fittings.
Hluav taws xob thiab Thermal conductivity
Ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm lub cev ntawm tooj liab yog nws qhov tshwj xeeb hluav taws xob thiab thermal conductivity. Tooj tooj yog qhov thib ob - tus neeg xyuas pib zoo tshaj plaws ntawm hluav taws xob tom qab nyiaj, ua rau nws xaiv qhov kev xaiv zoo tshaj plaws rau kev xaim, circuits, thiab cov khoom siv hluav taws xob. Nws cov thermal conductivity yog qhov zoo sib xws, tso cai rau nws kom hloov cov cua sov kom zoo, uas yog vim li cas tooj liab tau siv dav hauv cov kav dej kub thiab cov tub yees. Tsis tas li ntawd, tooj liab cov khoom hluav taws xob tseem nyob ruaj khov nyob rau lub sijhawm, ua rau nws zoo tagnrho rau cov ntawv thov tseem ceeb xws li kev xaim hluav taws xob thiab cov khoom siv hluav taws xob siab -.
Corrosion Resistance thiab Chemical Stability
Ntawm cov khoom siv tshuaj lom neeg ntawm tooj liab yog nws lub ntuj tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv tsis yog -oxidizing ib puag ncig. Thaum lub sij hawm, tooj liab tsim ib qho kev tiv thaiv patina uas ua los ntawm kev tiv thaiv corrosion ntxiv, ua kom lub neej ntev ntawm cov kav dej fittings siv nyob rau hauv vaj tse thiab kev lag luam dej. Lub durability thiab chemical inertness ntawm tooj liab ua rau nws haum rau marine daim ntaub ntawv, nrog rau cov shipbuilding thiab desalination khoom, raws li nws withstands dej ntsev thiab hnyav ib puag ncig yam tsis muaj degradation tseem ceeb.
Malleability, Ductility, thiab Mechanical Strength
Copper's mechanical zog muaj xws li zoo heev malleability thiab ductility, lub ntsiab lus nws yuav ua tau yooj yim zoo li tus los yog stretched yam tsis muaj kev tawg. Cov khoom zoo no ua rau nws nyiam cov khoom siv tooj liab uas yuav tsum tau ua kom raug. Nws lub zog txhua yam ua kom nws tuaj yeem tiv taus kev ntxhov siab yam tsis muaj kev tawg, ua rau nws zoo tagnrho rau cov tshuab dynamic xws li cov kav dej thiab cov kav dej. Tooj liab muaj qhov ceev ntawm 8.96 g ib cubic centimeter, thiab nws cov alloys, xws li tooj dag thiab tooj liab, txhim khu nws cov khoom siv rau kev siv tshwj xeeb.
Antimicrobial Properties
Ib qho tsawg dua -paub tab sis cov cuab yeej tseem ceeb ntawm tooj liab yog nws tus cwj pwm ntawm cov tshuaj tua kab mob. Copper ions cuam tshuam cov kab mob thiab kab mob, ua rau muaj kev cuam tshuam cov kab mob tsis zoo. Qhov no tau ua rau kev siv cov ntawv tooj liab hauv cov chaw kho mob thiab cov chaw ua zaub mov uas muaj kev nyiam huv yog qhov tseem ceeb, thiab tooj liab tau dhau los ua cov khoom siv nrov rau cov khoom siv kov xws li lub qhov rooj thiab cov railings hauv cov chaw pej xeem, pab txo kev kis kab mob.
Qhov ntom ntom thiab lwm yam khoom siv lub cev
Copper's reddish- xim txiv kab ntxwv thiab siab ceev ntawm 8.96 g ib cubic centimeter ua rau nws yog ib qho khoom zoo nkauj uas tsis tau muaj zog. Nws lub peev xwm los cuam tshuam lub teeb thiab tiv thaiv tarnishing ntxiv rau nws qhov kev thov hauv cov ntawv siv kho kom zoo nkauj. Tooj liab lub siab melting point ntawm txog 1085 degrees C thiab nws cov thermal expansion yam ntxwv pab rau nws haum rau industrial txheej txheem thiab daim ntaub ntawv uas yuav tsum tau kub kuj.
