Izintambo ze-aluminium alloy azizange zisetshenziswe isikhathi eside ezweni lakithi, kodwa sekuvele kunezimo ezibonisa ukuthi kunezingozi ezinkulu ezifihliwe kanye nezingozi ekusetshenzisweni kwezintambo ze-aluminium alloy emadolobheni, amafektri nasezimayini.Kuxoxwa ngamacala amabili asebenzayo alandelayo kanye nezici eziyisishiyagalombili eziholela ezingozini zezintambo ze-aluminium alloy.
Icala 1
Izintambo ze-aluminium alloy zazisetshenziswa ngamaqoqo esitshalweni sensimbi.Imililo emibili yenzeke onyakeni owodwa, okuholele ekuvaleni kwezinyanga eziyisigamu kanye nokulahleka kwezomnotho okuqondile kwama-yuan ayizigidi ezingama-200.
Leli ibhuloho elinekhebula eliye lalungiswa ngemuva komlilo.Iminonjana yomlilo isaqhubeka.
Icala lesibili
Izintambo ze-aluminium alloy zisetshenziswa ohlelweni lokusabalalisa izibani zedolobha eSifundazweni saseHunan.Phakathi nonyaka owodwa ngemva kokufakwa, ukugqwala okuqinile kwezintambo ze-aluminium alloy, okubangele ukulimala kwamajoyinti ekhebula namakhondakta, kanye nokuphelelwa amandla kwezintambo.
Ngalezi zimo ezimbili, singabona ukuthi ukuthandwa okukhulu kwekhebula le-aluminium alloy emadolobheni, izimboni kanye nezimayini eChina kushiye izingozi ezifihliwe emadolobheni, izimboni kanye nezimayini.Abasebenzisi abaqondi kahle izici eziyisisekelo zekhebula le-aluminium alloy, futhi ngaleyo ndlela balahlekelwa kakhulu.Uma abasebenzisi beqonda izici zekhebuli ye-aluminium alloy ekuthembekeni nasekuvikeleni umlilo kusenesikhathi, bazolahlekelwa kakhulu.Ubulili, ukulahlekelwa okunjalo kungagwenywa kusengaphambili.
Ngokwezici zezintambo ze-aluminium alloy, izintambo ze-aluminium alloy zinamaphutha emvelo ekuvimbeleni umlilo nokuvimbela ukugqwala.Kuboniswa ezicini eziyisishiyagalombili ezilandelayo:
1. Ukumelana nokugqwala, 8000 Series Aluminium ingxubevange ingaphansi kunejwayelekile ingxubevange ye-aluminium
I-GB/T19292.2-2003 Ithebula Elijwayelekile 1 Inothi 4 lithi ukumelana nokugqwala kwe-aluminium alloy kubi kakhulu kunokwe-aluminium alloy evamile futhi kubi kakhulu kunethusi, ngoba izintambo ze-aluminium alloy ziqukethe i-magnesium, ithusi, i-zinc nezakhi zensimbi, ngakho-ke ajwayele ukugqwala endaweni njengokuqhekeka kokugqwala kwengcindezi, ukugqwala kongqimba kanye nokugqwala kwe-intergranular.Ngaphezu kwalokho, i-8000 Series Aluminium alloy ingeyefomula ethanda ukugqwala, futhi izintambo ze-aluminium alloy kulula ukugqwala.Ukwengeza inqubo yokwelapha ukushisa, kulula ukubangela isimo somzimba esingalingani, okulula ukugqwala kunekhebula le-aluminium.Njengamanje, ama-alloys e-aluminium asetshenziswa ezweni lakithi ngokuyisisekelo ayi-8000 aluminium alloy series.
2. Ukumelana nezinga lokushisa kwe-aluminium alloy kuhluke kakhulu kulokho kwethusi.
Indawo yokuncibilika yethusi ngu-1080 kanti eye-aluminium ne-aluminium alloys ingu-660 ngakho-ke umqhubi wethusi uyisinqumo esingcono kumakhebuli aphikisayo.Manje abanye abakhiqizi bezintambo ze-aluminium alloy bathi bayakwazi ukukhiqiza izintambo ze-aluminium alloy refractory futhi baphumelele ukuhlolwa kwezindinganiso zikazwelonke ezifanele, kodwa awukho umehluko phakathi kwezintambo ze-aluminium alloy nezintambo ze-aluminium kulokhu.Uma izinga lokushisa liphakeme kune-melting point ye-aluminium alloy kanye nekhebula le-aluminium esikhungweni somlilo (ngenhla), kungakhathaliseki ukuthi yiziphi izinyathelo zokufakelwa izintambo ezithatha, izintambo Zizoncibilika ngesikhathi esifushane kakhulu futhi zilahlekelwe umsebenzi wayo wokuqhuba.Ngakho-ke, ama-alloys e-aluminium ne-aluminium akufanele asetshenziswe njengezikhondatha zamakhebula eziphikisayo noma kumanethiwekhi okusabalalisa amadolobha aminyene, izakhiwo, izimboni nezimayini.
3. I-thermal expansion coefficient ye-aluminium alloy iphakeme kakhulu kunaleyo yethusi, futhi leyo ye-AA8030 aluminium alloy iphakeme kakhulu kunaleyo yealloy evamile ye-aluminium.
Kungabonakala kuthebula ukuthi i-coefficient yokwandisa ukushisa kwe-aluminium iphakeme kakhulu kunaleyo yethusi.Ama-aluminium alloys AA1000 kanye ne-AA1350 athuthuke kancane, kuyilapho i-AA8030 iphakeme kakhulu kunaleyo ye-aluminium.I-coefficient yokwandisa okushisayo ephezulu izoholela ekuthinteni okubi kanye nendilinga ononya yamakhondatha ngemva kokunwetshwa nokufinyela kwe-thermal.Kodwa-ke, kukhona njalo iziqongo nezigodi ekunikezeni amandla, okuzobangela ukuhlolwa okukhulu ekusebenzeni kwekhebula.
4. I-aluminium alloy ayixazululi inkinga ye-aluminium oxidation
Ama-alloys e-aluminium noma ama-alloys e-aluminium avezwe emkhathini azokwakha ngokushesha ifilimu eqinile, ebophayo kodwa ebuthakathaka enogqinsi olulinganiselwa ku-10 nm, olunokumelana okuphezulu.Ubulukhuni bayo namandla okubopha kwenza kube nzima ukwakha othintana nabo abaqhubayo.Lesi yisizathu sokuthi kungani ungqimba lwe-oxide ebusweni be-aluminium ne-aluminium alloys kufanele lususwe ngaphambi kokufakwa.Indawo yethusi nayo iyakhipha i-oxidize, kodwa ungqimba lwe-oxide luthambile futhi kulula ukuhlephuka lube ama-semiconductors, enze ukuthintana kwensimbi-yensimbi.
5. Izintambo ze-aluminium alloy ziye zathuthukisa ukukhululeka kwengcindezi nokumelana nokunyakaza, kodwa zingaphansi kakhulu kunezintambo zethusi.
Izakhiwo ezinwabuzelayo ze-aluminium alloy zingathuthukiswa ngokungeza izakhi ezithile ku-aluminium alloy, kodwa izinga lokuthuthuka lilinganiselwe kakhulu uma liqhathaniswa ne-aluminium alloy, futhi lisekhona igebe elikhulu uma liqhathaniswa nethusi.Ukuthi ikhebula le-aluminium alloy lingathuthukisa yini ngempela ukumelana ne-creep lihlobene eduze nobuchwepheshe, ubuchwepheshe kanye nezinga lokulawula ikhwalithi lebhizinisi ngalinye.Lokhu kungaqiniseki ngokwakho kuyisici esiyingozi.Ngaphandle kokulawula okuqinile kobuchwepheshe obuvuthiwe, ukuthuthukiswa kokusebenza kwentambo ye-aluminium alloy ngeke kuqinisekiswe.
6. Ikhebula le-aluminium alloy ayixazululi inkinga yokuthembeka kokuxhuma kwe-aluminium
Kunezici ezinhlanu ezithinta ukuthembeka kwamalunga e-aluminium.Ama-alloys e-aluminium athuthuke kuphela endabeni eyodwa, kodwa awazange axazulule inkinga yamalunga e-aluminium.
Kunezinkinga ezinhlanu ekuxhumekeni kwe-aluminium alloy.I-creep and stress relaxation ye-8000 Series Aluminium alloy ithuthukisiwe kuphela, kodwa akukho ntuthuko eyenziwe kwezinye izici.Ngakho-ke, inkinga yokuxhuma isazoba yinkinga enkulu ethinta ikhwalithi ye-aluminium alloy.I-aluminium alloy nayo iwuhlobo lwe-aluminium hhayi into entsha.Uma igebe phakathi kwezakhiwo eziyisisekelo ze-aluminium nethusi lingaxazululeki, ingxube ye-aluminium ayikwazi ukufaka esikhundleni sethusi.
7. Ukumelana nokunyakazisa okungekuhle kwengxubevange ye-aluminium yasekhaya ngenxa yokulawulwa kwekhwalithi okungahambisani (ukwakheka kwealloyi)
Ngemuva kokuhlolwa kwe-POWERTECH eCanada, ukwakheka kwe-aluminium alloy yasekhaya akuzinzile.Umehluko wokuqukethwe kwe-Si kukhebuli ye-aluminium alloy yaseNyakatho Melika ungaphansi kuka-5%, kuyilapho lokho kwe-aluminium alloy yasekhaya kungu-68%, futhi i-Si iyingxenye ebalulekile ethinta izakhiwo ze-creep.Okusho ukuthi, ukumelana nokukhuphuka kwezintambo ze-aluminium alloy zasekhaya akukakakhiwa ubuchwepheshe obuvuthiwe.
8. Ubuchwepheshe obuhlangene bekhebula le-aluminium alloy yinkimbinkimbi futhi kulula ukushiya izingozi ezifihliwe.
Amalunga ekhebula le-aluminium alloy anezinqubo ezintathu ezingaphezu kwamajoyinti ekhebula lethusi.Ukususwa okusebenzayo kongqimba lwe-oxide kanye nokunameka kwama-antioxidants kuyisihluthulelo.Izinga lokwakhiwa kwasekhaya, izidingo zekhwalithi azilingani, zishiya izingozi ezifihliwe.Ngaphezu kwalokho, ngenxa yokuntuleka kwesistimu yesinxephezelo sezomthetho esiqinile e-China, imiphumela yokulahlekelwa ekugcineni ngokuyisisekelo icatshangwa abasebenzisi ngokwabo.
Ngaphezu kwalezi zici ezingenhla, ikhebula le-aluminium alloy nalo alinayo indinganiso ehlanganisiwe yokugeleza kokunqanyulwa, indawo yokuxhumana ayidluliswanga, ukukhuphuka kwamanje kwe-capacitive, ibanga lokubeka ikhebula le-aluminium alloy liba lincane noma linganele ukulisekela ngenxa ukwanda kwe-cross-section, ubunzima bokwakha bubangelwa ukwanda kwe-cable cross-section, ukufaniswa kwendawo yomsele wekhebula, ukukhuphuka okusheshayo kokugcinwa kanye nezindleko zengozi.Uchungechunge lwezinkinga zobungcweti, njengokukhuphuka kwezindleko zomjikelezo wokuphila kanye nokuntuleka kwamazinga okufanele abaklami bawalandele, njengokungaphathwa kahle noma ukunganakwa ngamabomu kwanoma iyiphi yazo, kwanele ukubangela abasebenzisi ukulahlekelwa okukhulu nokungenakulungiseka kanye nezingozi.
