conductivity yobhedu
Enye yezona mpawu zibalulekileyo zeubhedu olungenalothekukuba ine-conductivity egqwesileyo yombane, kunye ne-conductivity ye-58m / (Ω.mm square).Le propati yenza ubhedu lusetyenziswe ngokubanzi kumashishini ombane, ombane, onxibelelwano kunye nombane.Le conductivity yombane ephezulu yobhedu inxulumene nesakhiwo sayo se-athomu: xa ii-athom zobhedu ezininzi zidityanisiwe kwibhloko yobhedu, ii-electron zabo ze-valence azisekho kwii-athom zobhedu, ukuze zihambe ngokukhululekileyo kulo lonke ubhedu oluqinileyo., i-conductivity yayo ingokwesibini kuphela kweyesilivere.Umgangatho wamazwe ngamazwe wokuqhuba ubhedu kukuba ukuqhutyelwa kobhedu kunye nobude be-1m kunye nobunzima be-1g kwi-20 ° C kubonwa njenge-100%.I-teknoloji yangoku yokunyibilikisa ubhedu iye yakwazi ukuvelisa ibakala elifanayo lobhedu kunye ne-4% ukuya kwi-5% ephezulu kunomgangatho wamazwe ngamazwe.
I-Thermal conductivity yobhedu
Enye impembelelo ebalulekileyo yee-electron zasimahla kubhedu oluluqilima kukuba ine-thermal conductivity ephezulu kakhulu.I-thermal conductivity yayo yi-386W / (mk), eyesibini kuphela kwisilivere.Ukongeza, ubhedu luninzi kwaye luxabiso eliphantsi kunegolide nesilivere, ngoko ke lwenziwa kwiimveliso ezahlukeneyo ezinje ngeengcingo kunye neentambo, iitheminali zokuqhagamshela, imivalo yebhasi, iifreyimu ezikhokelayo, njl.Ubhedu lukwayinto ephambili yezixhobo ezahlukeneyo zokutshintshiselana kobushushu ezifana nokutshintsha ubushushu, iicondensers, kunye neeradiator.Isetyenziswa ngokubanzi koomatshini abancedisayo kwisikhululo samandla, ii-air conditioners, ifriji, iitanki zamanzi emoto, iigridi zabaqokeleli belanga, ukuchithwa kwamanzi olwandle kunye neyeza, ishishini lemichiza., i-metallurgy kunye nezinye iziganeko zokutshintsha ubushushu.
Ukumelana nokubola kobhedu
Ubhedu lunokumelana ne-corrosion elungileyo, lungcono kunentsimbi eqhelekileyo, kwaye lungcono kune-aluminiyam kwiatmosfera yealkaline.Ukulandelelana okunokwenzeka kobhedu ngu + 0.34V, ephakamileyo kuneye-hydrogen, ngoko ke yintsimbi enokuthi ibe yinto efanelekileyo.Izinga lokubola kobhedu kumanzi amatsha nalo liphantsi kakhulu (malunga ne-0.05mm/a).Yaye xa kusetyenziswa imibhobho yobhedu ukuthutha amanzi aphuma empompo, iindonga zemibhobho azigcini izimbiwa, ezingaphaya kokufikelela kwimibhobho yamanzi yentsimbi.Ngenxa yolu phawu, imibhobho yamanzi yobhedu, iifaucets kunye nezixhobo ezinxulumeneyo zisetyenziswa ngokubanzi kwizixhobo zokubonelela ngamanzi kwindawo yokuhlambela.I-Copper ixhathisa ngokugqithiseleyo kwi-corrosion ye-atmospheric, kwaye inokwenza ifilimu ekhuselayo ehlanganiswe nesiseko se-sulfate yethusi phezu komhlaba, okuyi-patina, kunye nokwakhiwa kweekhemikhali yiCuS04 * Cu (OH) 2 kunye neCuSO4 * 3Cu (OH) 2.Ngoko ke, ubhedu lusetyenziselwa ukwakha iipaneli zephahla, iipayipi zamanzi emvula, iipayipi eziphezulu kunye nezantsi, kunye nokufakelwa kwemibhobho;izikhongozeli zeekhemikhali kunye nezamayeza, izixhobo zokuvelisa, izihluzi zepulp;izixhobo zenqanawa, ii-propellers, ubomi kunye nothungelwano lwemibhobho yomlilo;iingqekembe zemali eziphothiweyo (ukumelana nokugqwala)), umhlobiso, iimbasa, iindebe, imifanekiso eqingqiweyo kunye nemisebenzi yezandla (ukumelana nokubola kunye nombala omhle), njl.
