Copper yog ib qho ntawm cov khoom siv dav siv ntau tshaj plaws, thiab nws cov khoom siv ntau tshaj li cov hlau ntshiab hauv ntau cov khoom siv hluav taws xob thiab thermal. Ntau tshaj li ib nrab ntawm tag nrho cov refined tooj liab yog hloov mus rau siab - tooj liab purity rau hluav taws xob kev lag luam txhua xyoo. Cov qib siv rau cov conductors yog txhob txwm khaws cia ntshiab heev, nrog tooj liab ntsiab lus ntawm 99.95% thiab siab dua, vim hais tias txawm me me heev ntawm impurities - phosphorus, arsenic thiab txhuas hauv particular - sharply txo hluav taws xob conductivity.
Vim li cas Purity Govers Conductivity
Conductivity nyob rau hauv tooj liab yog tswj los ntawm tsawg npaum li cas cov siv lead ua lattice cuam tshuam. Phosphorus yog qhov feem ntau ua rau cov impurity tsis zoo thiab txhob txwm tshaj tawm los ntawm cov neeg xyuas pib qib; arsenic thiab sulfur muaj qhov zoo sib xws, yog tias tsis muaj zog, cuam tshuam. Oxygen kuj tseem ceeb: ib qho me me ntawm cov pa tau yooj yim khaws thaum lub sij hawm ua kom zoo, thiab vim tias nws cuam tshuam nrog hydrogen thaum annealing lossis brazing nws tuaj yeem ua rau porosity thiab embrittlement. Vim li no, tooj liab npaj rau kev lag luam hluav taws xob feem ntau yog muab cov pa oxygen - tooj liab dawb.
Tus neeg xyuas pib qib: 99.95% tooj liab lossis siab dua, qis hauv phosphorus thiab arsenic
Oxygen- qib pub dawb: cov ntsiab lus oxygen tswj tau rau ob peb ntu ntawm ib lab
Deoxidised siab -phosphorus tooj liab: siv rau cov kav dej thiab vov tsev, tsis yog rau cov neeg siv khoom
Cov qauv siv dav dav: ASTM B49, ASTM B187 / B187M, EN 13601, GB / T 3952
Cov khoom siv hluav taws xob
Lub qhov hluav taws xob loj tshaj plaws rau cov tooj liab ntshiab yog cov tshuab hluav taws xob. Tooj liab yog siv nyob rau hauv zus tau tej cov generators, busbars, hwj chim thiab kev sib txuas lus cables, switchgear thiab transformers, raws li zoo raws li lub cev muaj zog windings, commutators thiab connector kho vajtse. Qhov laj thawj yog ncaj nraim: ntawm 100% IACS, tooj liab nqa ntau dua tam sim no rau ib chav tsev ntawm tus ntoo khaub lig-section dua li lwm yam kev coj ua lag luam, uas txo cov kev poob qis, kub nce thiab lub cev loj ntawm cov khoom siv.
Cov khoom siv cua sov
Copper lub thermal conductivity - txog 398 W / (m·K) ntawm 20℃- ua rau nws cov khoom siv rau kev hloov cua sov. Nws yog siv rau cov cua kub exchangers, condensers thiab evaporators, solar heating li xws li tiaj-plate collectors, radiator cores, thiab pipework nyob rau hauv tub yees thiab cua-cua txias systems. Nyob rau hauv txhua rooj plaub, cov hlau txav cua sov tawm ntawm qhov chaw sai txaus kom ua haujlwm kub hauv qhov kev txwv tsim.
Cov ntawv thiab cov lus qhia tshwj xeeb
Copper yog muab rau hauv ib tsev neeg ntawm cov ntawv zeb, txhua tus nrog nws tus kheej qhov ntev thiab cov khoom siv kho tshuab. Kev sib piv daim ntawv mus rau qhov kev qhia tshwj xeeb ntawm theem kev txiav txim kom tsis txhob muaj teeb meem thaum tsim khoom thiab kev pabcuam.

Architecture, Kev tsim kho thiab kev lag luam
Tshaj li hluav taws xob thiab thermal lub luag haujlwm, tooj liab ua haujlwm rau kev tsim vaj tsev thiab kev tsim vaj tsev dav dav vim nws qhov kev tiv thaiv corrosion, zoo li thiab yooj yim ntawm kev koom ua ke. Nws tshwm sim hauv vov tsev thiab phab ntsa cladding, cov khoom siv dej nag, cov kav dej thiab cov pa xa hluav taws xob, cov khoom siv hauv hiav txwv, thiab ua lub hauv paus alloying rau tooj dag thiab tooj liab. Copper compounds kuj tau siv hauv kev ua liaj ua teb thiab hauv qee cov txheej txheem tshuaj.
Ob lub ntsiab lus tseem ceeb tswj hwm feem ntau ntawm cov ntawv thov no. Ua ntej, tooj liab tsim muaj kev tiv thaiv patina thaum lub sij hawm, yog li nthuav tawm architectural tooj liab yuav tsum hloov xim ntau dua li degrade. Thib ob, tooj liab thiab hlau nyob rau hauv kev sib cuag ncaj qha tuaj yeem txhawb galvanic corrosion ntawm cov hlau hauv kev pabcuam ntub dej, yog li cov pob qij txha ntawm ob lub hlau feem ntau yog insulated.
Kev xav txog kev muag khoom
Vim tias tooj liab tuaj yeem rov ua dua tshiab yam tsis tau poob ntawm cov khoom, cov hlau thib ob yog qhov tseem ceeb ntawm cov khoom siv. Cov neeg yuav khoom yuav tsum paub meej txog qib, npau taws, conductivity thiab oxygen cov ntsiab lus uas yuav tsum tau siv thaum kawg, thiab xyuas tias daim ntawv pov thawj zeb hais txog cov qauv siv tau thiab ntsuas ntsuas. Rau kev ua haujlwm ntawm tus neeg xyuas pib, cov pa oxygen - qib pub dawb nrog cov ntawv pov thawj muaj txiaj ntsig yog qhov kev xaiv nyab xeeb tshaj plaws; rau thermal thiab architectural dej num, txheem ETP cov ntaub ntawv yog ib txwm txaus.
