Lapho ukhetha izinto zokwakha, ukukhiqiza, noma amaphrojekthi we-DIY, i-aluminium nensimbi engagqwali yizinsimbi ezimbili ezidume kakhulu. Kodwa yini ngempela ebenza bahluke? Noma ngabe ungunjiniyela, umuntu othanda ukuzilibazisa, noma ufuna ukwazi nje, ukuqonda ukuhlukana kwabo kungakusiza wenze izinqumo ezinolwazi. Kule bhulogi, sizohlukanisa izakhiwo zabo, izinhlelo zokusebenza, izindleko, nokunye okwengeziwe—okusekelwa imithombo engochwepheshe—ukuze sikusize ukhethe izinto ezifanele izidingo zakho.
1. Ukwakheka: Zenziwe Ngani?
Umehluko omkhulu phakathi kwe-aluminium nensimbi engagqwali usekubunjweni kwazo.
I-Aluminiumiyinsimbi engasindi, esiliva-mhlophe etholakala oqweqweni loMhlaba. I-aluminium ehlanzekile ithambile, ngakho-ke ivamise ukuhlanganiswa nezinto ezifana nethusi, i-magnesium, noma i-silicon ukuze kuthuthukiswe amandla. Isibonelo, ingxubevange ye-aluminium engu-6061 esetshenziswa kabanzi iqukethe i-magnesium ne-silicon.
Insimbi engagqwaliingxubevange esekwe ku-iron equkethe okungenani u-10.5% we-chromium, eyenza ungqimba lwe-passive oxide ukumelana nokugqwala.. Amamaki ajwayelekile afana nensimbi engagqwali engu-304 ahlanganisa ne-nickel ne-carbon.
2. Amandla Nokuqina
Izidingo zamandla ziyahlukahluka ngohlelo lokusebenza, ngakho-ke ake siqhathanise izakhiwo zabo zemishini.
Insimbi engagqwali:
Insimbi engagqwali inamandla kakhulu kune-aluminium, ikakhulukazi ezindaweni ezinengcindezi ephezulu. Isibonelo, insimbi engagqwali yebanga lama-304 inamandla aqinile angu-~505 MPa, uma kuqhathaniswa ne-aluminium engu-6061's ~310 MPa.
I-Aluminium:
Nakuba inamandla kancane ngevolumu, i-aluminium inesilinganiso esingcono samandla nesisindo. Lokhu kuyenza ifanelekele izingxenye ze-aerospace (njengamafreyimu endiza) nezimboni zezokuthutha lapho ukwehlisa isisindo kubalulekile.
Ngakho-ke, insimbi engagqwali inamandla uma sekukonke, kodwa i-aluminiyamu iyadlula lapho amandla angasindi abalulekile.
3. Ukumelana Nokugqwala
Zombili izinsimbi ziyamelana nokugqwala, kodwa izindlela zazo ziyahlukahluka.
Insimbi engagqwali:
I-Chromium kunsimbi engagqwali ihlangana nomoya-mpilo ukuze yakhe isendlalelo se-chromium oxide esivikelayo. Lolu ngqimba oluzilaphayo luvimbela ukugqwala, noma luklwetshiwe. Amabanga afana nensimbi engagqwali angu-316 engeza i-molybdenum ukuze imelane namanzi anosawoti kanye namakhemikhali.
I-Aluminium:
I-Aluminiyamu ngokwemvelo yakha ungqimba oluncane lwe-oxide, luyivikele ekufakweni kwe-oxidation. Kodwa-ke, ijwayele ukugqwala i-galvanic uma ibhangqwe nezinsimbi ezingafani ezindaweni ezinomswakama. I-anodizing noma i-coatings ingathuthukisa ukumelana kwayo.
Ngakho-ke, insimbi engagqwali inikeza ukumelana nokugqwala okuqinile, kuyilapho i-aluminium idinga ukwelashwa okuvikelayo ezimeni ezinzima.
4. Isisindo: I-Aluminium Iyawina Yezicelo Ezingasindi
Ukuminyana kwe-aluminium cishe ku-2.7 g/cm³, ngaphansi kwengxenye yesithathu yensimbi engagqwali engu-8 g/cm³,okuyinto engasindi kakhulu.
·Izindiza kanye nezingxenye zezimoto
·Izinto zikagesi eziphathwayo (isb, amalaptop)
·Izimpahla zabathengi njengamabhayisikili nezimpahla zokukhempa
I-Stainless steel heft iyinzuzo ezinhlelweni ezidinga ukuzinza, njengemishini yezimboni noma izisekelo zezakhiwo.
5. I-Thermal kanye ne-Electric Conductivity
I-Thermal Conductivity:
I-Aluminium ihambisa ukushisa okungcono okungu-3x kunensimbi engagqwali, iyenze ifanelekele osinki bokushisa, i-cookware, namasistimu e-HVAC.
I-Electrical Conductivity:
I-Aluminiyamu isetshenziswa kakhulu emigqeni yamandla kanye nezintambo zikagesi ngenxa ye-conductivity yayo ephezulu (61% yethusi). Insimbi engagqwali iyikhondukta empofu futhi ayivamisile ukusetshenziswa ezinhlelweni zikagesi.
6. Ukuqhathaniswa Kwezindleko
I-Aluminium:
Ngokuvamile ishibhile kunensimbi engagqwali, nezintengo zishintshashintsha ngokusekelwe ezindlekweni zamandla (ukukhiqizwa kwe-aluminium kudla amandla). Kusukela ngo-2023, i-aluminium ibiza ~$2,500 toni ngayinye ye-metric.
Insimbi engagqwali:
Ibiza kakhulu ngenxa yezakhi ze-alloying njenge-chromium ne-nickel. Ibanga 304 lensimbi engagqwali okumaphakathi ~$3,000 ton metric ngayinye.
Ithiphu:Kumaphrojekthi alungele isabelomali lapho isisindo sibalulekile, khetha i-aluminium. Ngokuphila isikhathi eside ezindaweni ezinokhahlo, insimbi engagqwali ingase ithethelele izindleko eziphezulu.
7. Ukushisekela kanye Nokwakha
I-Aluminium:
Ithambile futhi kulula ukuyisika, ukugoba, noma ukuyikhipha. Ilungele izimo eziyinkimbinkimbi kanye ne-prototyping esheshayo. Kodwa-ke, ingakwazi ukuhlanganisa amathuluzi ngenxa yezinga layo eliphansi lokuncibilika.
Insimbi engagqwali:
Kunzima kakhulu emshinini, kudinga amathuluzi akhethekile kanye nesivinini esincane. Kodwa-ke, inomumo onembile futhi iphetha kahle, ifanela imishini yezokwelapha noma imininingwane yezakhiwo.
Ekushiseleni, insimbi engagqwali idinga isivikelo segesi engasebenzi (TIG/MIG), kuyilapho i-aluminium idinga ukubamba okunolwazi ukuze igweme ukungqubuzana.
8. Izicelo Ezivamile
Ukusetshenziswa kwe-aluminium:
·I-Aerospace (amafuselage endiza)
·Ukupakisha (amathini, i-foil)
·Ukwakhiwa (amafasitela, ukufulela)
·Ezokuthutha (izimoto, imikhumbi)
Ukusetshenziswa Kwensimbi Engagqwali:
·Izinsimbi zokwelashwa
·Imishini yasekhishini (osinki, okokusika)
·Amathangi okucubungula amakhemikhali
·I-Hardware yasolwandle (ukufakwa kwezikebhe)
9. Ukusimama kanye Nokugaywa kabusha
Zombili izinsimbi zingaphinda zisetshenziswe ngo-100%:
·Ukugaywa kabusha kwe-aluminium konga u-95% wamandla adingekayo ekukhiqizeni okuyisisekelo.
Isiphetho: Yikuphi Okufanele Ukhethe?
Khetha i-Aluminium Uma:
·Udinga impahla engasindi, eyongayo.
·I-Thermal/electrical conductivity ibalulekile.
·Le phrojekthi ayibandakanyi ingcindezi eyeqile noma izindawo ezonakalisayo.
Khetha Insimbi Engagqwali Uma:
·Amandla nokumelana nokugqwala yizinto eziza kuqala.
·Isicelo sibandakanya amazinga okushisa aphezulu noma amakhemikhali anokhahlo.
·Ukukhanga kobuhle (isb., ukuqeda okupholishiwe) kuyabalulekile.
