I-Aluminium iyisici sensimbi iyinsimbi ekhanyayo esiliva-emhlophe ethambile.Izimpahla zivame ukwenziwa zibe izinti, amashidi, amafoyili, izimpushana, amaribhoni kanye nemicu.Emoyeni omanzi, ingenza ifilimu ye-oxide evimbela ukugqwala kwensimbi.Impushana ye-aluminium ingasha ngamandla uma ishiswa emoyeni, futhi ikhiphe ilangabi elikhazimulayo elimhlophe.Incibilika ku-dilute sulfuric acid, i-nitric acid, i-hydrochloric acid, i-sodium hydroxide nesisombululo se-potassium hydroxide, engancibiliki emanzini.Ukuminyana okuhlobene 2.70.Iphoyinti lokuncibilika 660 ℃.Iphoyinti lokubilisa 2327 ℃.Okuqukethwe yi-aluminium oqweqweni lomhlaba kungokwesibili ngemuva kwe-oxygen ne-silicon, okukleliswe endaweni yesithathu, futhi iyisakhi sensimbi esigcwele kakhulu oqweqweni lomhlaba.Ukuthuthukiswa kwezimboni ezintathu ezibalulekile zezindiza, ukwakhiwa kanye nezimoto kudinga ukuthi izakhiwo ezibonakalayo zibe nezakhiwo eziyingqayizivele ze-aluminium nama-alloys ayo, okwenza kube lula kakhulu ukukhiqizwa nokusebenzisa le aluminium entsha yensimbi.Uhlelo lokusebenza lubanzi kakhulu.
01. Isisindo esilula, amandla athile aphezulu kanye nokumelana nokugqwala kwe-aluminium yizici ezivelele zokusebenza kwayo.I-Aluminium inokuminyana okuphansi kakhulu okungu-2.7 g/cm kuphela
Nakuba ithambile, ingenziwa ibe ama-alloys e-aluminium ahlukahlukene, njenge-aluminium eqinile, i-aluminium eqinile kakhulu, i-aluminium evimbela ukugqwala, i-aluminium ekhonjiwe, njll. Lawa ma-alloys e-aluminium asetshenziswa kakhulu ezindizeni, ezimotweni, ezitimeleni, emkhunjini nakwezinye izindawo. izimboni zokukhiqiza.Ngaphezu kwalokho, amarokhethi asemkhathini, izithuthuthu zasemkhathini, namasathelayithi okwenziwa nawo asebenzisa isamba esikhulu se-aluminum nama-alloys ayo e-aluminium.
02. Amandla athile e-aluminium alloy aphezulu
03. Ukumelana nokugqwala okuhle
I-Aluminiyamu iyinsimbi esebenza kakhulu, kodwa izinzile ezindaweni ezijwayelekile ze-oxidizing.Lokhu ukwakheka kwefilimu ye-oxide ebusweni be-aluminium ku-oxygen, umoya-mpilo kanye nezinye izixuku.Ifilimu ye-aluminium oxide ayinakho kuphela ukumelana nokugqwala okuqinile, kodwa futhi inezinga elithile lokuhlukanisa.
04. I-conductivity ye-aluminium ingeyesibili kuphela kunesiliva, ithusi negolide
Nakuba i-conductivity yayo ingu-2/3 kuphela wethusi, ukuminyana kwayo kungu-1/3 kuphela wethusi, ngakho-ke ukudlulisa inani elifanayo likagesi, ikhwalithi yocingo lwe-aluminium iyingxenye kuphela yocingo lwethusi.Ngakho-ke, i-aluminium inezinhlobonhlobo zokusetshenziswa embonini yokukhiqiza izinto zikagesi, imboni yezintambo nezintambo kanye nemboni yomsakazo.
05. I-Aluminium iwumqhubi omuhle wokushisa
I-conductivity yayo eshisayo iphindwe izikhathi ezingu-3 kunensimbi futhi izikhathi ezingu-10 kunezinsimbi ezingenasici.I-Aluminium ingasetshenziswa embonini ukwenza izinto ezishintshashintshayo zokushisa, izinto zokukhipha ukushisa kanye nezitsha zokupheka.
06. I-Aluminium ine-ductility enhle
Ingokwesibili ngemva kwegolide nesiliva ekudukeni futhi ingenziwa amafoyili azacile kuno-0.006 mm.Lawa ma foil e-aluminium asetshenziswa kakhulu ukupakisha ugwayi, amaswidi, njll. Angenziwa futhi abe izintambo ze-aluminium namapheshana, akhishwe abe yizinto ezihlukahlukene ezimise okukhethekile, futhi angagingqwa emikhiqizweni ehlukahlukene ye-aluminium.I-Aluminium ingasikwa, ibhojwe futhi ishiselwe ngezindlela ezivamile.
07. I-Aluminium ayikazibuthe
Ayikhiqizi izinkambu kazibuthe ezengeziwe futhi ayiphazamisi amathuluzi anembayo.
08. I-Aluminium inezinto ezimunca umsindo, nomsindo nawo ungcono
Ngakho-ke, i-aluminium isetshenziselwa uphahla emakamelweni okusakaza kanye nezakhiwo zesimanje ezinkulu.
