Kubomi bethu bemihla ngemihla nakumashishini amaninzi, sihlala sijikelezwe ziimveliso ezenziwe ngentsimbi okanye nge-aluminium. Ukususela kwizakhiwo eziphakamileyo ezibumba isixeko sethu ukuya kwiimoto esiziqhubayo kunye neetini ezigcina iziselo zethu esizithandayo, ezi zinto zimbini zidlala indima ebalulekileyo. Kodwa xa kufikwa ekukhetheni phakathi kwentsimbi kunye ne-aluminium kwisicelo esithile, isigqibo sinokuba lula kakhulu. Masiqalise uphando oluneenkcukacha ukuze sibone ukuba yeyiphi enokuba ilungele iimfuno ezahlukeneyo.
Intsimbi kunye neAluminiyam: Intshayelelo
Intsimbi
Intsimbi yingxubevange eyenziwe ngentsimbi nekhabhoni. Ubungakanani bekhabhoni, obuqhele ukuba phakathi kwe-0.2% ukuya kwi-2.1% ngobunzima, buchaphazela kakhulu iimpawu zayo.Kukho iintlobo ezininzi zentsimbi. Intsimbi yekhabhoni, umzekelo, yaziwa ngamandla ayo kunye nokufikeleleka kwayo. Isetyenziswa kakhulu ekwakheni nasekwenzeni. Intsimbi ye-alloy, kwelinye icala, inezinto ezongezelelweyo ezifana ne-manganese, i-chromium, okanye i-nickel ezongeziweyo ukuphucula iimpawu ezithile ezifana nokuqina, ukuqina, okanye ukumelana nokugqwala. Cinga nge-I - beams eqinileyo esetyenziswa ekwakheni izakhiwo okanye izixhobo zentsimbi engatyiwayo ezihlala ixesha elide ekhitshini lakho - zonke ezi ziimveliso zokuguquguquka kwentsimbi.
I-aluminiyam
I-aluminiyam yintsimbi ekhaphukhaphu efumaneka kakhulu kuqweqwe loMhlaba. Ihlala ifumaneka kwi-bauxite ore kwaye ifuna amandla amaninzi ukuze ikhutshwe.I-aluminium ikwimo yayo ecocekileyo ithambile, kodwa xa ixutywe nezinto ezifana nobhedu, i-magnesium, okanye i-zinc, iba namandla ngakumbi. Ii-alloys ze-aluminium eziqhelekileyo ziquka i-6061, esetyenziswa kakhulu kwiindawo ezisetyenziswa ngokubanzi njengeenxalenye zeemoto kunye ne-7075, eyaziwa ngamandla ayo aphezulu kwaye isetyenziswa rhoqo kwiindawo zeenqwelo moya. Jonga-jonga, uya kubona i-aluminium kwizinto zemihla ngemihla ezifana neetini zesiselo, iifreyimu zeefestile, kwanakwizixhobo ze-elektroniki eziphezulu.
Uqhankqalazo lweePropati eziPhakathi
Uxinano
Omnye womahluko ophawulekayo phakathi kwentsimbi kunye ne-aluminium bubuninzi bazo. Intsimbi idla ngokuba nobunzima obumalunga ne-7.85 grams nge-cubic centimeter nganye. Ngokwahlukileyo koko, ubuninzi be-aluminium bumalunga ne-2.7 grams nge-cubic centimeter nganye. Lo mahluko ubalulekileyo wenza i-aluminium ibe lula kakhulu. Kwishishini leenqwelo-moya, umzekelo, ikhilogremu nganye yokunciphisa ubunzima inokukhokelela ekongeni amafutha amaninzi ngexesha lokuphila kwenqwelo-moya. Yiyo loo nto i-aluminium iyinto ekhethwayo yokwakha imizimba kunye namaphiko eenqwelo-moya. Nangona kunjalo, kwizicelo apho ubunzima bungeyona nto ixhalabisayo, kwaye kufuneka uzinzo ngenxa yobunzima, njengakwezinye iintlobo zoomatshini bemizi-mveliso okanye iziseko zezakhiwo ezinkulu, ubuninzi bentsimbi bunokuba luncedo.
Amandla
Intsimbi yaziwa ngamandla ayo aphezulu. Iintsimbi zentsimbi ezinekhabhoni ephezulu kunye neentsimbi ze-alloy zinokufikelela kumandla aphezulu kakhulu okutyhala, nto leyo eyenza ukuba zilungele ukusetyenziswa apho ukuqina kwesakhiwo phantsi kwemithwalo enzima kubalulekile. Umzekelo, iibhulorho ezixhonyiweyo ezijikeleza imilambo emikhulu zixhomekeke kwiintambo zentsimbi kunye neebhanti ukumelana nobunzima bezithuthi kunye namandla okusingqongileyo. Nangona kunjalo, ii-alloy ze-aluminium nazo zenze inkqubela enkulu kumandla. Ezinye ii-alloy ze-aluminium ezinamandla aphezulu, njengalezo ezisetyenziswa kwi-aerospace, zinokukhuphisana nomlinganiselo wamandla ukuya kubunzima beentsimbi ezithile. Kwishishini leemoto, i-aluminium isetyenziswa ngakumbi kwizakhiwo zomzimba ukunciphisa ubunzima ngelixa isagcina imigangatho yokhuseleko, njengoko ukuqhubela phambili kwitekhnoloji ye-alloy kuphucule iimpawu zayo zamandla.
Ukuqhuba
Xa kufikwa kwi-conductivity yombane kunye ne-thermal, i-aluminium ikhanya ngaphezu kwentsimbi. I-aluminium yi-conductor ebalaseleyo yombane, yiyo loo nto isetyenziswa rhoqo kwimigca yokudlulisa umbane. Inika ulungelelwano oluhle phakathi kwe-conductivity kunye neendleko, ngakumbi xa kuthelekiswa ne-conductors ezibiza kakhulu ezifana ne-copper. Ngokuphathelele i-conductivity yobushushu, ukukwazi kwe-aluminium ukudlulisa ubushushu ngokukhawuleza kwenza kube lukhetho oludumileyo kwii-heat sinks kwizixhobo ze-elektroniki. Umzekelo, ii-cooling fins kwi-CPU yekhompyutha zihlala zenziwe nge-aluminium alloy ukuze zikhuphe ubushushu ngokufanelekileyo kwaye zithintele ubushushu obugqithisileyo. Intsimbi, nangona inokuqhuba umbane kunye nobushushu, yenza njalo ngesantya esiphantsi kakhulu, okwenza ukuba ingafanelekanga ukusetyenziswa apho i-conductivity ephezulu ibalulekile.
Iipropati zeKhemikhali: Ukujonga ngokusondeleyo
Ukumelana nokugqwala
Intsimbi inesithende se-Achilles xa kufikwa ekuboleni. Xa kukho ioksijini kunye nokufuma, intsimbi ingena lula kwi-oxidation, yenze umhlwa. Oku kunokwenza buthathaka isakhiwo ngokuhamba kwexesha. Ukulwa noku, kusetyenziswa amanyathelo ahlukeneyo okukhusela, anjengokupenda, ukugquma (ukugquma nge-zinc), okanye ukusebenzisa intsimbi engatyiwayo, equlethe i-chromium eyenza umaleko we-oxide ongasebenziyo. I-aluminium, kwelinye icala, inenzuzo yendalo. Xa ivezwa emoyeni, yenza umaleko we-oxide obhityileyo, oxineneyo kumphezulu wayo. Le maleko isebenza njengomqobo, ithintela ukuvuthelana nokuvuthelana. Oku kwenza i-aluminium ifaneleke kakhulu kwizicelo zangaphandle, njengakwiindawo eziselunxwemeni apho umoya onetyuwa unokuba ngumhlwa ngakumbi. Umzekelo, ucingo lwe-aluminium kunye nefenitshala yangaphandle zinokumelana neminyaka yokuchatshazelwa zizinto ngaphandle kokuwohloka okukhulu.
I-Reactivity yeKhemikhali
I-Aluminiyam yintsimbi esabelayo kakhulu. Kwiimeko ezithile, inokusabela ngamandla, ngakumbi ngee-asidi. Nangona kunjalo, umaleko we-oxide okhuselayo owakha phezu komphezulu wayo phantsi kweemeko eziqhelekileyo uthintela uninzi lweempendulo. Kwezinye iinkqubo zoshishino, i-reactivity ye-aluminiyam inokusetyenziswa. Umzekelo, kwimveliso yeekhemikhali ezithile, i-aluminiyam ingasetyenziswa njenge-arhente yokunciphisa. Intsimbi, xa ithelekiswa nayo, ayisabela kakhulu phantsi kweemeko eziqhelekileyo. Kodwa kwiindawo ezinobushushu obuphezulu okanye ezine-asidi ephezulu/ezisisiseko, inokuhlangabezana neempendulo zeekhemikhali ezinokuchaphazela ukuthembeka kwayo. Umzekelo, kwezinye izityalo zeekhemikhali, kufuneka amanqanaba akhethekileyo entsimbi ukuze imelane nemiphumo yokubola yeekhemikhali ezinobungozi.
Uthelekiso loKusebenza koCwangco
Ukuyilwa kunye nokuCwangciswa
Intsimbi inika iindlela ezahlukeneyo zokubumba.
