Tooj liab yog ib qho ntawm cov khoom siv ntau yam thiab siv dav hauv ntiaj teb, tau txais txiaj ntsig rau nws cov khoom sib xyaw ua ke ntawm lub cev ntawm tooj liab, tshuaj lom neeg ntawm tooj liab, thiab cov khoom siv ntawm tooj liab. Paub txog nws cov reddish- txiv kab ntxwv xim thiab siab conductivity, tooj liab tau ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam, suav nrog kev tsim kho, hluav taws xob, thiab kav dej. Nws cov khoom ua rau nws yog ib qho tseem ceeb rau kev tsim khoom xws li peb cov kav dej tooj liab, tooj liab, thiab tooj liab fittings. Qhov blog no tshawb txog cov khoom ntawm tooj liab thiab hais txog nws qhov tseem ceeb hauv ntau daim ntawv thov.
Tau txais cov ntaub ntawv qhia ntxaws ntxaws
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 nyiam xaiv rau cov xaim, circuits, thiab cov khoom siv hluav taws xob. Nws cov thermal conductivity yog qhov zoo sib xws, tso cai rau nws hloov cov cua sov kom zoo, uas yog vim li cas tooj liab tau siv dav hauv cov ntawv thov xws li GNEE Copper's Heat Exchanger Tubes 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 covtshuaj muaj zog ntawm tooj liabyog nws tej yam ntuj tso tsis kam rau corrosion, tshwj xeeb tshaj yog nyob rau hauv uas tsis yog -oxidizing ib puag ncig. Thaum lub sij hawm, tooj liab tsim ib qho kev tiv thaiv patina, uas ua raws li ib tug barrier tiv thaiv ntxiv corrosion. Qhov no ua kom lub neej ntev ntawm cov khoom zoo li Copper Fittings rau Cov kav dej, feem ntau siv hauv cov tsev nyob thiab cov dej hauv tsev.
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 tiv taus raug 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 xws li Copper Coils, uas yuav tsum tau ua kom tiav. Nws lub zog txhua yam kuj ua kom ntseeg tau tias 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 / cm³, uas, ua ke nrog nws cov khoom siv dag zog, ua rau nws haum rau kev siv hnyav - xws li peb Cov Hluav Taws Xob Tsheb Npav thiab lwm yam khoom siv. Tsis tas li ntawd, nws cov alloys, xws li tooj dag thiab bronze, 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 coj mus rau kev siv GNEE Copper Sheets hauv cov chaw kho mob thiab chaw ua zaub mov, qhov kev nyiam huv yog qhov tseem ceeb.
Cov khoom siv tshuaj tua kab mob ntawm cov tooj liab kuj tau ua rau nws yog ib qho khoom siv nrov rau qhov chaw kov, xws li lub qhov rooj thiab cov railings, hauv cov chaw pej xeem, pab txo qis kev kis kab mob.
Qhov ntom ntom thiab lwm yam khoom siv lub cev
Lub cev muaj zog ntawm tooj liab, xws li nws cov xim liab - cov xim txiv kab ntxwv thiab qhov ntom ntom ntawm 8.96 g / cm³, ua rau nws ua kom zoo nkauj thiab cov khoom siv zoo. Nws lub peev xwm los cuam tshuam lub teeb thiab tiv thaiv tarnishing ntxiv rau nws qhov kev thov hauv cov ntawv thov zoo nkauj. Copper lub siab melting point (1,085 degree) thiab thermal expansion yam ntxwv ntxiv ua rau nws haum rau cov txheej txheem kev lag luam thiab cov ntawv thov uas yuav tsum tau ua kom sov.
