Histori ea makotikoti a aluminium
Mekotla ea ho paka ea biri ea tšepe le lino tse tahang li na le nalane ea lilemo tse fetang 70. Mathoasong a lilemo tsa bo-1930, United States e ile ea qala ho hlahisa makotikoti a tšepe ea biri. Lekotikoti lena la likarolo tse tharo le entsoe ka tinplate. Karolo e ka holimo ea 'mele oa tanka e na le sebōpeho sa khoune,' me karolo e ka holimo e na le sekoahelo sa moqhaka. Ponahalo ea eona e akaretsang ha e fapane haholo le ea libotlolo tsa khalase, kahoo mohala oa ho tlatsa botlolo ea khalase o ne o sebelisetsoa ho tlatsa qalong. E ne e se ho fihlela lilemong tsa bo-1950 moo mohala o khethehileng oa ho tlatsa o neng o fumaneha. Sekoahelo sa cana se ile sa fetoha sebopeho se bataletseng bohareng ba lilemo tsa bo-1950 'me sa ntlafatsoa ho ba sekoahelo sa lesale la aluminium lilemong tsa bo-1960.
makotikoti a seno a aluminium a ile a hlaha pejana ho elella bofelong ba lilemo tsa bo-1950, 'me makotikoti a DWI a likarolo tse peli a ile a tsoa ka molao mathoasong a lilemo tsa bo-1960. Ntlafatso ea makotikoti a aluminium e potlakile haholo. Qetellong ea lekholo lena la lilemo, tšebeliso ea selemo le selemo e fihlile ho feta limilione tse likete tse 180, e leng sehlopha se seholo ka ho fetisisa lefatšeng la makotikoti a tšepe (hoo e ka bang limilione tse likete tse 400). Tšebeliso ea aluminium e sebelisoang ho etsa makotikoti a aluminium le eona e ntse e hola ka potlako. Ka 1963, e ne e le haufi le zero. Ka 1997, e fihlile ho lithane tse limilione tse 3,6, tse lekanang le 15% ea kakaretso ea tšebeliso ea lisebelisoa tse sa tšoaneng tsa aluminium lefatšeng.
Theknoloji ea tlhahiso ea makotikoti a aluminium e 'nile ea ntlafatsoa khafetsa.
Ka lilemo tse mashome, theknoloji ea tlhahiso ea makotikoti a aluminium e ntse e ntlafatsoa khafetsa. Boima ba makotikoti a aluminium bo fokotsehile haholo. Mathoasong a lilemo tsa bo-1960, boima ba makotikoti a sekete a aluminium (ho kenyeletsoa le 'mele le sekoahelo) bo ile ba fihla lik'hilograma tse 55 (hoo e ka bang lik'hilograma tse 25),' me bohareng ba lilemo tsa bo-1970 e ile ea theohela ho lik'hilograma tse 44,8 (25 kg). Lik’hilograma), e ile ea fokotsoa hore e be liponto tse 33 (lik’hilograma tse 15) ho elella bofelong ba lilemo tsa bo-1990, ’me hona joale e fokotsoe ho ba ka tlaase ho liponto tse 30, e leng hoo e ka bang halofo ea lilemo tse 40 tse fetileng. Lilemong tse 20 ho tloha 1975 ho isa 1995, palo ea makotikoti a aluminium (li-ounces tse 12 ka matla) a entsoeng ka ponto e le 'ngoe ea aluminium e eketsehile ka 35%. Ho phaella moo, ho ea ka lipalo-palo tsa k'hamphani ea Amerika ALCOA, thepa ea aluminium e hlokahalang bakeng sa makotikoti a sekete a aluminium e fokotsoe ho tloha ho lik'hilograma tse 25.8 ka 1988 ho ea ho lik'hilograma tse 22,5 ka 1998 'me ea fokotseha ho ea ho liponto tse 22.3 ka 2000. makotikoti a aluminium United States a fokotsehile haholo, ho tloha ho 0.343 mm ka 1984 ho ea ho 0,285 mm ka 1992 le 0.259 mm ka 1998.
Khatelo-pele e bobebe ea aluminium can lids e boetse e hlakile. Botenya ba aluminium can lids bo theohile ho tloha 039 mm mathoasong a lilemo tsa bo-1960 ho ea ho 0.36 mm lilemong tsa bo-1970, ho tloha 0.28 mm ho ea ho 0.30 mm ka 1980, le ho 0.24 limilimithara bohareng ba bo-1980. Bophara ba sekoahelo sa makotikoti le bona bo fokotsehile. Boima ba li-lids bo 'nile ba tsoela pele ho fokotseha. Ka 1974, boima ba makotikoti a sekete a aluminium e ne e le liponto tse 13, ka 1980 bo fokotsehile ho liponto tse 12, ka 1984 bo fokotsehile ho liponto tse 11, ka 1986 bo fokotsehile ho liponto tse 10, mme ka 1990 le 1992 bo fokotsehile ho liponto tse 9 ka tlhompho. 8 pounds, e fokotsehile ho lik'hilograma tse 6.6 ka 2002. Lebelo la ho etsa makotikoti le ntlafalitsoe haholo, ho tloha ho 650-1000cpm (feela ka motsotso) lilemong tsa bo-1970 ho ea ho 1000-1750cpm lilemong tsa bo-1980 le ho feta 2000cpm hona joale.
