Iintambo ze-aluminium azizange zisetyenziswe ixesha elide kwilizwe lethu, kodwa sele kukho iimeko ezibonisa ukuba kukho iingozi ezinkulu ezifihliweyo kunye neengozi ekusebenziseni iintambo ze-aluminium alloy kwizixeko, iifektri kunye nemigodi.Ezi meko zilandelayo zimbini ezisebenzayo kunye nezinto ezisibhozo ezikhokelela kwiingozi zengozi yeentambo ze-aluminium alloy zixoxwa.
Ityala loku-1
Iintambo ze-aluminiyam zisetyenziswe kwiibhetshi kwisityalo sentsimbi.Imililo emibini yenzeke ngonyaka omnye, okubangele ukuvalwa kwesiqingatha senyanga kunye nelahleko yezoqoqosho ngokuthe ngqo ye-200 yezigidi zeeyuan.
Le yibhulorho yeentambo eziye zalungiswa emva komlilo.Umkhondo womlilo usabonakala.
Ityala lesibini
Iintambo ze-aluminium ze-alloy zisetyenziselwa inkqubo yokusabalalisa ukukhanya kwesixeko kwiPhondo laseHunan.Kwisithuba esingangonyaka emva kofakelo, ukonakala okunamandla kweentambo ze-aluminiyam ze-alloy zenzekile, okubangele ukonakala kwamalungu eentambo zentambo kunye neekhondaktha, kunye nokusilela kombane kwiintambo.
Ngezi meko zimbini, sinokubona ukuba ukuthandwa okukhulu kwentambo ye-aluminium alloy kwizixeko, iifektri kunye nemigodi yaseTshayina kushiye iingozi ezifihlakeleyo kwizixeko, iifektri kunye nemigodi.Abasebenzisi abaqondi kakuhle kwiipropathi ezisisiseko ze-aluminium alloy cable, kwaye ngaloo ndlela bafumana ilahleko enkulu.Ukuba abasebenzisi baqonda iimpawu ze-aluminium alloy cable ekuthembekeni komlilo kunye nokukhuselwa kwangaphambili, baya kulahlekelwa yilahleko enkulu.Ukwabelana ngesondo, ilahleko enjalo inokuphetshwa kwangaphambili.
Ngokweempawu zeentambo ze-aluminium alloy, iintambo ze-aluminium zineziphene zendalo ekuthinteleni umlilo kunye nokukhusela ukubola.Iboniswa kule miba isibhozo ilandelayo:
1. Ukumelana nokubola, 8000 Series Aluminiyam ingxubevange ingaphantsi kunesiqhelo aluminiyam ingxubevange.
I-GB/T19292.2-2003 Itheyibhile esemgangathweni ye-1 Inqaku le-4 lichaza ukuba ukuxhathisa kwe-corrosion ye-aluminium alloy kubi kakhulu kune-alloy ye-aluminium eqhelekileyo kwaye kubi kakhulu kunobhedu, kuba iintambo ze-aluminium alloy ziqulethe i-magnesium, ubhedu, i-zinc kunye nezinto zentsimbi, ngoko ke batyekele kukonakala kwendawo okufana nokuqhekeka koxinzelelo lwe-corrosion, i-layer corrosion kunye ne-intergranular corrosion.Ngaphezu koko, 8000 Series Aluminiyam ingxubevange yeyefomula umhlwa-prone, kunye neentambo aluminiyam ingxubevange kulula ukuba corroded.Ukongeza inkqubo yokunyanga ukushisa, kulula ukubangela isimo somzimba esingalinganiyo, ekulula ukugqwala kunentambo ye-aluminium.Okwangoku, ii-alloys ze-aluminium ezisetyenziswa kwilizwe lethu ziyi-8000 ze-aluminium alloy series.
2. Ukumelana nobushushu be-aluminium alloy kuhluke kakhulu kubhedu.
Indawo yokuncibilika kobhedu yi-1080 kwaye i-aluminium kunye ne-aluminium alloys yi-660 ngoko umqhubi wobhedu lukhetho olungcono kwiintambo eziphikisayo.Ngoku abanye abavelisi be-aluminium alloy cable babanga ukuba bayakwazi ukuvelisa iintambo ze-aluminium alloy refractory kwaye baphumelele uvavanyo olufanelekileyo lwemigangatho yesizwe, kodwa akukho mahluko phakathi kweentambo ze-aluminium kunye neentambo ze-aluminium kule nkalo.Ukuba iqondo lokushisa liphezulu kune-melting point ye-aluminium alloy kunye ne-aluminium cable kwiziko lomlilo (ngasentla), kungakhathaliseki ukuba yiyiphi imilinganiselo yokukhusela iintambo ezithathayo, iintambo ziya kunyibilika ngexesha elifutshane kakhulu kwaye zilahlekelwe ngumsebenzi wayo wokuqhuba.Ke ngoko, i-aluminiyam kunye ne-aluminium alloys akufuneki isetyenziswe njengee-conductors zentambo okanye kuthungelwano oluxineneyo lokuhambisa ezidolophini, izakhiwo, iifektri kunye nemigodi.
3. I-coefficient yokwandiswa kwe-thermal ye-aluminium alloy iphezulu kakhulu kuneyobhedu, kwaye i-alloy ye-AA8030 ye-aluminium iphezulu nangaphezulu kune-alloy ye-aluminium eqhelekileyo.
Inokubonwa kwitheyibhile ukuba i-coefficient yokwandiswa kwe-thermal ye-aluminium iphezulu kakhulu kunobhedu.I-aluminium alloys AA1000 kunye ne-AA1350 iphuculwe kancinane, ngelixa i-AA8030 iphezulu nangaphezulu kune-aluminium.I-coefficient yokwandiswa kwe-thermal ephezulu iya kukhokelela kuqhagamshelwano olubi kunye nesangqa esikhohlakeleyo sabaqhubi emva kokwandiswa kwe-thermal kunye nokunciphisa.Nangona kunjalo, kukho rhoqo iincopho kunye neentlambo kumandla ombane, okuya kubangela uvavanyo olukhulu ekusebenzeni kwekhebula.
4. I-aluminium alloy ayizisombululi ingxaki ye-aluminium oxidation
I-aluminium alloys okanye i-aluminium alloys evezwe emoyeni iya kwenza ngokukhawuleza ifilimu enzima, edibeneyo kodwa enqabileyo enobunzima obumalunga ne-10 nm, enokumelana okuphezulu.Ukuqina kwayo kunye namandla okudibanisa kwenza kube nzima ukwenza unxibelelwano oluqhubayo.Esi sizathu sokuba i-oxide layer phezu kwe-aluminium kunye ne-aluminium alloys kufuneka isuswe ngaphambi kokufakwa.Umphezulu wobhedu nawo wenza i-oxidize, kodwa umaleko we-oxide uthambile kwaye kulula ukuqhekeza kwii-semiconductors, ukwenza unxibelelwano lwesinyithi-yentsimbi.
5. Iintambo ze-aluminiyam ziphucule ukuphumla koxinzelelo kunye nokumelana nokunyuka, kodwa zingaphantsi kakhulu kuneentambo zobhedu.
Iipropathi ezirhubuluzayo zealluminiyam ialloy zinokuphuculwa ngokudibanisa izinto ezithile kwialloyi ye-aluminiyam, kodwa iqondo lophuculo lilinganiselwe kakhulu xa lithelekiswa nealloyi ye-aluminium, kwaye kusekho umsantsa omkhulu xa kuthelekiswa nobhedu.Nokuba intambo yealluminiyamu yealloyi inokuphucula ngokwenene ukuxhathisa kwe-creep inxulumene ngokusondeleyo netekhnoloji, itekhnoloji kunye nenqanaba lolawulo lomgangatho weshishini ngalinye.Oku kungaqiniseki ngokwako kungumngcipheko.Ngaphandle kolawulo olungqongqo lwetekhnoloji evuthiweyo, ukuphuculwa kokusebenza kwentambo ye-aluminium alloy ayinakuqinisekiswa.
6. Intambo ye-aluminium alloy ayisombululi ingxaki yokuthembeka koqhagamshelwano lwe-aluminium
Kukho izinto ezintlanu ezichaphazela ukuthembeka kwamalungu e-aluminium.I-aluminium alloys iphuculwe kuphela kumcimbi omnye, kodwa ayizange isombulule ingxaki yamalungu e-aluminium.
Kukho iingxaki ezintlanu kunxibelelwano lwe-aluminium alloy.I-creep and stress relaxation ye-8000 Series Aluminium alloy iphuculwe kuphela, kodwa akukho phuculo lwenziwe kwezinye iinkalo.Ngoko ke, ingxaki yokudibanisa iya kuba yingxaki enkulu echaphazela umgangatho we-aluminium alloy.I-aluminiyam i-alloy nayo luhlobo lwe-aluminiyam kwaye kungekhona into entsha.Ukuba umsantsa phakathi kweepropati ezisisiseko ze-aluminium kunye nobhedu awusonjululwanga, i-alloy ye-aluminium ayinakuthatha indawo yobhedu.
7. Ukuxhatshazwa okungahambi kakuhle kwe-alloys yasekhaya ye-aluminium ngenxa yokungahambelani kokulawulwa komgangatho (ukwakheka kwealloyi)
Emva kovavanyo lwe-POWERTECH eCanada, ukubunjwa kwe-alloy ye-aluminium yasekhaya ayizinzanga.Umahluko weSiqulatho seSi kwiNorth American aluminium alloy cable ingaphantsi kwe-5%, ngelixa i-alloy ye-aluminium yasekhaya yi-68%, kwaye i-Si yinto ebalulekileyo echaphazela iipropati ze-creep.Oko kukuthi, ukuxhathisa kwe-creep yeentambo ze-aluminium alloy yasekhaya ayikasekwa buchwephesha obuvuthiweyo.
8. I-Aluminiyam i-alloy cable iteknoloji edibeneyo iyinkimbinkimbi kwaye kulula ukuyishiya iingozi ezifihliweyo.
I-Aluminiyam i-alloy cable joints ineenkqubo ezintathu ezingaphezulu kuneentambo zobhedu.Ukususwa okusebenzayo komgangatho we-oxide kunye nokugquma kwe-antioxidants yeyona nto iphambili.Inqanaba lokwakhiwa kwekhaya, iimfuno zomgangatho azilingani, zishiya iingozi ezifihliweyo.Ngaphezu koko, ngenxa yokungabikho kwenkqubo engqongqo yembuyekezo yetyala lomthetho e-China, iziphumo zelahleko yokugqibela ekusebenzeni zicingelwa ngabasebenzisi ngokwabo.
Ukongeza kwezi zinto zingasentla, intambo ye-aluminium alloy nayo ayinayo umgangatho odibeneyo wokuhamba kwe-cut-off, i-terminal yoqhagamshelo ayigqithiswanga, ukunyuka kwe-capacitive yangoku, umgama wokubeka umgama we-aluminium alloy cable uba mxinwa okanye akwanelanga ukuxhasa ngenxa yombane. ukwanda kwe-cross-section, ubunzima bokwakha bubangelwa ukunyuka kwe-cable cross-section, ukuhambelana kwendawo yomsele wentambo, ukunyuka ngokukhawuleza kokugcinwa kunye neendleko zomngcipheko.Uluhlu lweengxaki zobuchwephesha, ezifana nokunyuka kweendleko zomjikelo wobomi kunye nokungabikho kwemigangatho elandelwa ngabaqulunqi, njengokuphatha ngokungafanelekanga okanye ukungahoywa ngabom kuyo nayiphi na kuzo, kwanele ukuba kubangele abasebenzisi ukuba bahlupheke kakhulu kwaye balahlekelwe yilahleko kunye neengozi.
