Ka mahele heheʻe i ka wahi o ka Aluminum

Aluminum - Lightweight metala me ka silvery keʻokeʻo hue, pahee (hiki ke lena me kona mau lima), e lawelawe 'ia pono, oiai ma ka Ia manawa ikaika kupono. He he alakaʻi mele maikaʻi no ka wela a me ka uila. Pure Aluminum ua aneane hoʻohana ', kona noi ua hoʻomaʻamaʻa i loko o ka palapala o ka oka a me ka keleawe, kalapona, ke tina, titanium, manganese a me ka kiniki. No ka uila a me ka thermal conductivity Aluminum kekona wale nō i ke kālā, a me ke keleawe ulaula. I ka Ia manawa, impurities vanadium, chromium a me manganese emi i kēia mau mea kiko'î.

Aluminum reacts me nāʻakika a me alkalis e ho okumu chlorides, sulfates, aluminates, a me nā hui. I ka lewa koke kapa komo iā ia mea hiki ke hooheheeia'okesaside ho film i malama ia mai hou'okesaside. Ka mahele heheʻe i ka wahi o ka Aluminum mea i loko o 660,1 degere, ka mea hiki ke hooheheeia ma kii i palapala mai i ke castability maikai. No keia mea hiki ke hooheheeia ua wehewehe aku ma kiʻekiʻe ductility, anu ia'ku, ia'ku i ka popopo ma ka reacting me ka i puhi ia ka wai a me ka hou.

Mau loea, uaʻike ia i ka ka popopo ia'ku hilinaʻi nui ma luna o ka maemae o Aluminum - ka mea kiekie oia ka mea mea, no ka oi aku o ka ea. ka popopo ke kumu paha ia i kaʻilikai pōʻino o ka'okesaside ho film. Hoao ia Aluminum mahele heheʻe i ka piʻina me ka māhuahua maemae. Ai maikaʻi castability, metala i crystallization hoʻolako nui shrinkage, keia inideka mea nui i loko o ka hana o ka metala kauoha ninini.

Ka mahele heheʻe i ka wahi o ka Aluminum hiki oko ma ka hoʻohanaʻia me ka huikala. Aluminum? iecaianoaaiiuo nā alakaʻi i a ianoiyuaa a Rusia, kaʻAmelika Hui Pūʻia i loko o ke ao nei, Canada, Australia. Aluminum hoʻohana 'ana i kekahi pono nui huahelu, ko kākou mau kūpuna i loko o ka palapala o ka Aluminum i huiʻia (alum) Ua hoʻohana' ia e like me ka astringent ma ka laau lapaau, no ka tanning o E hūnā i nā mea e holo ana i ka holopapa ola o ka pena.

Lawa haʻahaʻa mahele heheʻe i ka mahana Aluminum ae e hoʻoheheʻe ia i loko o primitive ana.

Ma ke ano maoli, ia lŘlŘ Aluminum'okesaside (corundum), ka mea, ua hoʻohana 'ia e like me he abrasive, a me kona Lolina - sapeiro a me ka saredio - e pili ana i ka waeʻano o na pohaku makamae. Mai ka maemae Aluminum mea o ka uuku pono no oaoieei-noi, pinepine ka mea, ua hoʻohana 'ia me ka maka mea no ka hana i kekahi mau oka a pau. Huahelu o ka Aluminum oka a ka loa nui, ka mea, ua mau ka moʻolelo (hoʻohana 'ana i kekahi mau loea).

Currently, no kēia mau oka a hua mai la i ka ai ipu, E hiki anei ia, lumi kuke oihana a pau a me nā hale mau. Nui nā mea kūʻai mai Aluminum oka a pau i ke kaʻa, uila, mea hana, Nine Inch, malu, metallurgical na hana. I ka wela e hehee Aluminum, ua laweʻia i loko o ka mooolelo i loko o ka hana o ke keʻena māhele no ka mea e malu ai, a me ka aerospace nukelea na hana.

Kekahi o ka loa e like me ka ole-ferrous oka a ka duralumin, e hoʻomohala i ka hope kenekulia ma ka German lunaʻenehana A. Wilma. Heheʻe wahi duralumin ua ma kahi o 650 degere. Ke ae pā o ka hana mea hou i hana muaʻole ninoieo i loko i ka Aluminum-muli oka a ma hope o ka wela iapaau ana i kiekie ae ka ikaika a me ka paakiki. Kēia koke i hoʻohana o ka hoʻomalu, a e i ka pono o na aeronautics. Ka hou oka a ua lilo kekahi o ka papa kuhikuhiE mall mea ma ka mokulele.

Currently, i ka manawa i manaoia duralumin nuiʻano o ka Aluminum oka a wehewehe aku ma kiʻekiʻe ikaika. Hoikehonua, koe nae keleawe oka a pau i loaʻa ka manganese, silikone, makanekiuma, etc., ka mea, kokoke i ka ikaika o ka mehana kila. I kēia lā, e hoʻomano hoʻohana i kēia mau oka a pau i loko o ka mokulele hana, ma ka hana o ka kiʻekiʻe-mämä holo Loko, a ma kekahi'ē aʻe hihia.
