Uya kufunda kwakhona malunga nemingcipheko ebalulekileyo yophumezo, kubandakanywa ii-mechanics ze-galvanic corrosion kunye nokwanda kokumelana, okufunekayo kwiinkcukacha ezikhuselekileyo. Ngokufunda kakuhle le migaqo, unokwakha iinkqubo zombane ezikhuselekileyo ngelixa ulungiselela uhlahlo lwabiwo-mali lweprojekthi yakho.
Izinto eziphambili zokuThatha
I-Conductivity Baseline: Intsimbi enegalvanized iqhuba umbane malunga ne-10% ukuya kwi-30% yempumelelo yobhedu olusulungekileyo, nto leyo eyenza ukuba ibe yiconductor esezantsi kodwa isebenze kakhulu ekubekweni phantsi nasekukhuseleni isakhiwo.
Imida yesicelo: Ilungele ukukhuselwa komatshini (i-conduits), i-high-resistance grounding (HRG), kunye nokuchithwa kombane. Ayilunganga, ukuhanjiswa kwamandla okuqhubekayo ngenxa yokwanda kobushushu.
Ukuthintelwa kobusela: Kwiiprojekthi ezinkulu kunye neeprojekthi ezikude, ukucacisa isinyithi segalvanized kunciphisa kakhulu iindleko zizonke ngokususa umngcipheko omkhulu wokubiwa ohambelana nobhedu.
Imingcipheko yokuPhunyezwa: Ukudibana ngokuthe ngqo phakathi kwentsimbi yegalvanized kunye nobhedu kubangela ukubola kwegalvanic; izihlanganisi ze-bimetallic kufuneka zixelwe.
Yenziwa Njani Intsimbi Yesinyithi? (Izinto zoMzimba)
I-Core Metric
Makhe sijonge i-core metric. Silinganisa i-conductivity njengomlinganiselo ngokuchasene nezixhobo eziqhuba kakhulu ezifana nobhedu kunye ne-aluminiyam. Intsimbi ekhandiweyo isebenza ngokumalunga ne-10% ukuya kwi-30% yokusebenza kakuhle kobhedu olusulungekileyo. Unokuzibuza malunga nomgangatho we-zinc wangaphandle. Le ngubo ibhityileyo ekhuselayo ayitshintshi kakhulu isiseko sesinyithi sokuqhuba. I-substrate yentsimbi engaphantsi ichaza ngokuyinhloko ukuhamba kombane. I-Zinc ngokwayo ineempawu ezifanelekileyo zombane. Nangona kunjalo, abavelisi bafaka le ngubo kumaleko amancinci kakhulu, ngokuqhelekileyo kuphela ii-micrometers ezimbalwa. Ke ngoko, ukusebenza kombane ngobuninzi kuxhomekeke ngokupheleleyo kwikristale yentsimbi yombindi wentsimbi.
Imiba ephazamisana nokusebenza
Izinto ezininzi zomzimba kunye nokusingqongileyo zithintela ukuhamba kwe-electron kule nto. Kuya kufuneka uphendule ngezi ziguquko zahlukileyo ngexesha lobunjineli kunye nesigaba soyilo.
Ukubunjwa kwezinto eziphathekayo: I-chemistry yangaphakathi ibaluleke kakhulu. Umxholo wekhabhoni ongaphezulu kwe-0.3% unqanda ukuhamba kwe-electron. Iiathom zekhabhoni ezingaphakathi ziphazamisa i-iron crystal lattice efanayo. Olu kuphazamiseka lusasaza ii-electron njengoko zihamba, nto leyo eyandisa ngokusebenzayo ukuxhathisa kombane wesinyithi.
Ukutshintsha kweThermal: Ubushushu butshintsha yonke into kubunjineli bombane. Ukuxhathisa kukhula ngokukhawuleza xa amaqondo obushushu okusebenza edlula i-100°C.
