Kubomi bethu bemihla ngemihla nakumashishini amaninzi, sihlala singqongwe ziimveliso ezenziwe ngentsimbi okanye ialuminiyam. Ukusuka kwizakhiwo eziphakamileyo ezibonisa ubume bedolophu ukuya kwiimoto esiziqhubayo kunye neetoti ezigcina iziselo esizithandayo, ezi zinto zimbini zidlala indima ebalulekileyo. Kodwa xa kuziwa ekukhetheni phakathi kwentsimbi kunye ne-aluminium kwisicelo esithile, isigqibo sinokuba kude ngokuthe ngqo. Masiqalise uphononongo oluneenkcukacha ukubona ukuba yeyiphi enokuthi ilunge ngakumbi kwiimfuno ezahlukeneyo.
Intsimbi kunye neAluminiyam: Intshayelelo
Intsimbi
Intsimbi yi-alloy eyenziwe ngentsimbi kunye nekhabhoni. Umxholo wekhabhoni, ngokuqhelekileyo ukusuka kwi-0.2% ukuya kwi-2.1% ngobunzima, uchaphazela kakhulu iimpawu zayo.Kukho iintlobo ezininzi zentsimbi. Ngokomzekelo, intsimbi yekhabhoni iyaziwa ngamandla ayo kunye nokufikeleleka kwayo. Isetyenziswa kakhulu kulwakhiwo nakwimveliso. Intsimbi ye-alloy, kwelinye icala, inezinto ezongezelelweyo ezifana ne-manganese, i-chromium, okanye i-nickel eyongeziweyo ukunyusa iimpawu ezithile ezinjengokuqina, ukuqina, okanye ukuxhathisa ukubola. Cinga nge-I eyomeleleyo - imiqadi esetyenziselwa ukwakhiwa kwesakhiwo okanye i-stainless ehlala ixesha elide-impahla yentsimbi ekhitshini lakho - ezi zimveliso zonke zentsimbi.
Aluminiyam
I-aluminiyam yintsimbi ekhaphukhaphu neninzi kuqweqwe loMhlaba. Ngokuqhelekileyo ifumaneka kwi-bauxite ore kwaye idinga umthamo omkhulu wamandla ukukhupha.I-aluminiyam ekwimo yayo esulungekileyo iyathamba noko, kodwa xa ixutywe nezinto ezifana nobhedu, i-magnesium, okanye i-zinc, yomelela ngakumbi. I-alloys eqhelekileyo ye-aluminium ibandakanya i-6061, esetyenziswa ngokubanzi ngokubanzi-izicelo zenjongo ezifana neendawo zemoto kunye ne-7075, eyaziwa ngokuba namandla aphezulu kwaye isetyenziswa rhoqo kwizinto ze-aerospace. Jonga ngapha nangapha, kwaye uya kubona i-aluminiyam kwizinto zemihla ngemihla ezifana neetoti zesiselo, iifreyimu zefestile, kunye nakwizinto zombane eziphezulu.
Imbonakalo yeempawu zePhysical
Ukuxinana
Owona mahluko mkhulu phakathi kwentsimbi kunye ne-aluminiyam kukuxinana kwazo. Intsimbi ngokuqhelekileyo inoxinano malunga ne-7.85 grams cubic centimeter nganye. Ngokwahlukileyo, ubuninzi be-aluminiyam bumalunga ne-2.7 grams nge-cubic centimeter nganye. Lo mahluko ubalulekileyo wenza ialuminiyam ibe khaphukhaphu kakhulu. Kushishino lweenqwelomoya, umzekelo, ikhilogram nganye yokunciphisa ubunzima inokukhokelela ekongeni amafutha amaninzi kubomi benqwelomoya. Yiyo loo nto i-aluminiyam iyinto ekhethwayo yokwakha imizimba yenqwelomoya kunye namaphiko. Nangona kunjalo, kwizicelo apho ubunzima bungaxhalabiyo, kwaye uzinzo ngenxa yobunzima obufunekayo, njengakwezinye iintlobo zoomatshini boshishino okanye iziseko zezakhiwo ezinkulu, ukuxinana okuphezulu kwentsimbi kunokuba luncedo.
Amandla
Intsimbi idume ngamandla ayo aphezulu. Intsimbi yekhabhoni ephezulu kunye neentsimbi zealloyi zinokufikelela kumandla aphezulu kakhulu, zizenze zilungele usetyenziso apho isidima solwakhiwo phantsi kwemithwalo enzima ibalulekile. Ngokomzekelo, iibhulorho ezinqunyanyiswayo ezinqumla kwimijelo emikhulu yamanzi zixhomekeke kwiintambo zentsimbi kunye nemiqadi ukuze zimelane nobunzima bezithuthi kunye namandla okusingqongileyo. Iialloyi ze-aluminiyam, nangona kunjalo, nazo zenze inkqubela enkulu ngamandla. Ezinye ii-alloys ze-aluminiyam eziphezulu, ezifana nezo zisetyenziswa kwi-aerospace, zinokukhuphisana namandla-ukuya kumlinganiselo wobunzima beentsimbi ezithile. Kwimizi-mveliso yeemoto, i-aluminium isanda kusetyenziswa kwizakhiwo zomzimba ukunciphisa ubunzima ngelixa igcina imigangatho yokhuseleko, njengoko ukuqhubela phambili kwi-teknoloji ye-alloy kuye kwaphucula iimpawu zayo zamandla.
Ukuqhuba
Xa kuziwa kwi-conductivity yombane kunye ne-thermal, i-aluminium idlula intsimbi. I-aluminiyam yeyona nto ibalaseleyo yokuqhuba umbane, yiyo loo nto iqhele ukusetyenziswa kwiintambo zothumelo lombane. Inika ibhalansi elungileyo phakathi kwe-conductivity kunye neendleko, ngakumbi xa kuthelekiswa nabaqhubi ababiza kakhulu njengobhedu. Ngokubhekiselele kwi-thermal conductivity, ukukwazi kwe-aluminium ukudlulisa ubushushu ngokukhawuleza kwenza kube yinto ethandwayo yokukhetha ukushisa kwizixhobo zombane. Umzekelo, iifins zokupholisa kwi-CPU yekhompyuter zihlala zenziwe nge-aluminium alloy ukuze zikhuphe ngokufanelekileyo ubushushu kwaye zithintele ukufudumeza. Insimbi, ngelixa ikwazi ukuqhuba umbane kunye nokushisa, yenza oko kwizinga eliphantsi kakhulu, lenze ukuba lingabikho ukufaneleka kwizicelo apho i-conductivity ephezulu iyimfuneko.
Iipropati zeMichiza: Ukujongwa ngokusondeleyo
Ukunyangwa kokuMhlwa
Intsimbi inesithende se-Achilles xa kufikwa kumhlwa. Phambi kweoksijini kunye nomswakama, insimbi ingena ngokukhawuleza kwi-oxidation, yenze i-rust. Oku kunokusenza buthathaka isakhiwo ngokuhamba kwexesha. Ukulwa nale nto, kusetyenziswa iindlela ezahlukeneyo zokukhusela, ezifana nepeyinti, i-galvanizing (i-coating nge-zinc), okanye ukusebenzisa insimbi engenasici, equkethe i-chromium eyenza i-passive oxide layer. I-aluminium, ngakolunye uhlangothi, inenzuzo yendalo. Xa ibonakaliswe emoyeni, yenza umaleko obhityileyo, oxineneyo weoksidi kumphezulu wayo. Olu luhlu lusebenza njengesithintelo, lukhusela i-oxidation eyongezelelweyo kunye nokubola. Oku kwenza i-aluminiyam ilunge kakhulu kwizicelo zangaphandle, njengakwimimandla eselunxwemeni apho umoya onetyuwa unokugqwalisa. Ngokomzekelo, iingcingo ze-aluminium kunye nefenitshala yangaphandle inokumelana neminyaka yokuvezwa kwezinto ngaphandle kokuthotywa okukhulu.
I-Chemical Reactivity
I-Aluminiyam yintsimbi esebenzayo ngokwentelekiso. Kwiimeko ezithile, inokusabela ngamandla, ngakumbi ngeeasidi. Nangona kunjalo, umaleko weoksidi okhuselayo owenzeka kumphezulu wawo phantsi kweemeko eziqhelekileyo unqanda ukusabela okuninzi. Kwezinye iinkqubo zoshishino, ukusebenza kwakhona kwe-aluminiyam kunokufakwa. Ngokomzekelo, kwimveliso yeekhemikhali ezithile, i-aluminium ingasetyenziswa njenge-arhente yokunciphisa. Insimbi, ngokuthelekisa, ayisebenzi kangako phantsi kweemeko eziqhelekileyo. Kodwa kwindawo ephezulu yobushushu okanye eneasidi/esisiseko, inokuchaphazeleka kwimichiza enokuchaphazela ingqibelelo yayo. Ngokomzekelo, kwezinye izityalo zemichiza kufuneka intsimbi ekumgangatho okhethekileyo ukuze kuxhaswe ukonakala kwemichiza eyingozi.
Uthelekiso lweNdlela yokuSebenza
Ukuqulunqa kunye nokuLungiswa
Insimbi ibonelela ngeendlela ezahlukeneyo zokubumba. Ukuqulunqa yindlela eqhelekileyo apho isinyithi sifudumala kwaye sibunjwe ngokufaka amandla oxinzelelo.Oku kulungele ukwenza iindawo ezomeleleyo nezintsokothileyo, njengee-crankshafts kwiinjini. Ukuqengqeleka yenye inkqubo apho intsimbi idlula ngeerola ukuvelisa amaphepha, iipleyiti, okanye iiprofayili ezahlukeneyo. Ishishini leemoto lihlala lisebenzisa isitampu, uhlobo lwenkqubo yokubumba ukubanda, ukwenza iipaneli zomzimba wemoto ukusuka kumaphepha entsimbi. I-aluminiyam nayo ithambile kakhulu kwaye inokwakheka lula. I-Extrusion yinkqubo ethandwayo ye-aluminium, ngexesha apho isinyithi sinyanzeliswa ngokufa ukudala iimilo ezide kunye nezifanayo. Yile ndlela iifreyimu zefestile ze-aluminium zenziwe. I-Die-casting isetyenziselwa ngokubanzi kwi-aluminiyam, eyenza ukuveliswa kweendawo eziyinkimbinkimbi kunye neenkcukacha, ezifana neebhloko ze-injini kwiimoto ezininzi zanamhlanje.
Ukusebenza kweWelding
Intsimbi ye-welding ingaba yinkqubo enzima. Iindidi ezahlukeneyo zentsimbi zifuna ubuchule obuthile bokudibanisa kunye nezixhobo zokuzalisa.
