Ake sifunde mayelana nezakhiwo kanye nokusetshenziswa kwe-aluminium ndawonye

1. Ukuminyana kwe-aluminium kuncane kakhulu, kuphela 2.7g/cm. Nakuba ithambile, ingenziwa ibe yizinhlobonhloboama-alloys e-aluminium, njenge-aluminium eqinile, i-ultra hard aluminium, i-rust proof aluminium, i-cast aluminium, njll. Lawa ma-alloys e-aluminium asetshenziswa kakhulu ezimbonini zokukhiqiza ezifana nezindiza, izimoto, izitimela nemikhumbi. Ngaphezu kwalokho, amarokhethi asemkhathini, imikhumbi-mkhathi, namasathelayithi okwenziwa nawo asebenzisa isamba esikhulu se-aluminum nama-alloys ayo. Isibonelo, indiza ye-supersonic yakhiwe cishe ngama-70% e-aluminium nama-alloys ayo. I-Aluminium iphinde isetshenziswe kakhulu ekwakheni imikhumbi, umkhumbi omkhulu wabagibeli uvame ukudla amathani ayizinkulungwane ezimbalwa ze-aluminium.

2. I-conductivity ye-aluminium ingeyesibili kuphela kunesiliva nethusi. Nakuba i-conductivity yayo ingu-2/3 kuphela wethusi, ukuminyana kwayo kuyi-1/3 kuphela yethusi. Ngakho-ke, lapho uthutha inani elifanayo likagesi, ikhwalithi yocingo lwe-aluminium iyingxenye kuphela yocingo lwethusi. Ifilimu ye-oxide engaphezulu kwe-aluminium ayinalo nje kuphela ikhono lokumelana nokugqwala, kodwa futhi inezinga elithile lokufakelwa, ngakho-ke i-aluminium inezinhlobonhlobo zezinhlelo zokusebenza embonini yokukhiqiza ugesi, imboni yocingo nekhebula, kanye nembonini engenazintambo.

 
3. I-Aluminium ingumqhubi omuhle wokushisa, ene-thermal conductivity enkulu ngokuphindwe kathathu kunensimbi. Embonini, i-aluminiyamu ingasetshenziswa ukwenza izinto ezishintshashintshayo zokushisa, izinto zokukhipha ukushisa, nezitsha zokupheka.

 
4. I-Aluminium ine-ductility enhle (yesibili kuphela kugolide nesiliva), futhi ingenziwa ibe ucwecwe lwe-aluminiyamu mncane kuno-0.01mm emazingeni okushisa aphakathi kuka-100 ℃ no-150 ℃. Lawa ma foil e-aluminium asetshenziswa kakhulu ukupakisha ugwayi, amaswidi, njll. Angenziwa futhi abe izintambo ze-aluminium, amapheshana e-aluminium, futhi agingqelwe emikhiqizweni ehlukahlukene ye-aluminium.

 
5. Ingaphezulu le-aluminium aligqwali kalula ngenxa yefilimu elivikelayo le-oxide eliminyene, futhi livame ukusetshenziselwa ukwenza ama-reactors amakhemikhali, amadivaysi ezokwelapha, izinto zesiqandisi, imishini yokuhluza i-petroleum, amapayipi kawoyela negesi, njll.

 
6. Impushana ye-Aluminium inombala ocwebezelayo omhlophe (ngokuvamile umbala wensimbi oyimpushana ngokuvamile umnyama), futhi ngokuvamile isetshenziswa njengesimbozo, esivame ukwaziwa ngokuthi impushana eyisiliva noma upende oyisiliva, ukuvikela imikhiqizo yensimbi ekugqwaleni kanye nokuthuthukisa izinto zayo. ukubukeka.

 
7. I-Aluminium ingakhulula inani elikhulu lokushisa nokukhanya okukhazimulayo lapho ishiswa umoya-mpilo, futhi ivame ukusetshenziselwa ukwenza izingxube eziqhumayo, njengeziqhumane ze-ammonium aluminium (ezenziwe ngengxube ye-ammonium nitrate, impushana yamalahle, impushana ye-aluminium, intuthu emnyama, nezinye izinto eziphilayo ezivuthayo), izingxube ezivuthayo (njengamabhomu namagobolondo enziwe nge-aluminium thermite engasetshenziswa ukuhlasela okunzima ukuthungela okuhlosiwe noma amathangi, izibhamu, njll.), kanye nezingxube zokukhanyisa (njenge-barium nitrate 68%, i-aluminium impushana engu-28%, neglue yezinambuzane 4%).

 
8. I-aluminium thermite ivame ukusetshenziselwa ukuncibilikisa izinsimbi eziphikisayo kanye nama-welding steel rails. I-Aluminium nayo isetshenziswa njenge-deoxidizer enqubweni yokwenza insimbi. I-aluminium powder, i-graphite, i-titanium dioxide (noma amanye ama-oxide ensimbi ancibilika phezulu) axutshwe ngokufanayo ngesilinganiso esithile futhi ambozwe ensimbi. Ngemuva kokubala izinga lokushisa eliphezulu, kwenziwa izitsha zobumba zensimbi ezinokushisa okuphezulu, ezinezinhlelo zokusebenza ezibalulekile kubuchwepheshe be-rocket kanye ne-missile.

 
9. Ipuleti le-aluminum liphinde libe nokusebenza okuhle kokubonisa ukukhanya, libonisa imisebe ye-ultraviolet enamandla kunesiliva. Uma i-aluminium ihlanzekile, iba ngcono ikhono layo lokubonisa. Ngakho-ke, ngokuvamile isetshenziselwa ukukhiqiza izibonisi zekhwalithi ephezulu, njengezibonisi zesitofu selanga.

10. I-Aluminium inezinto ezimunca umsindo nemisindo emihle, ngakho uphahla emakamelweni okusakaza nezakhiwo ezinkulu zesimanje nazo zenziwe nge-aluminium.

 
11. Ukumelana nezinga lokushisa eliphansi: I-Aluminiyamu ikhulise amandla angenawo ama-brittleness emazingeni okushisa aphansi, okuyenza ibe into efanelekile kumadivayisi angashisi kancane njengeziqandisi, iziqandisi, izimoto zeqhwa zase-Antarctic, nezindawo zokukhiqiza i-hydrogen oxide.

 
12. I-amphoteric oxide
