Factory Custom Aluminium Coil Aluminium Sheet
Silvery dawb lub teeb hlau. Ductile. Cov khoom siv feem ntau yog ua los ntawm cov pas nrig, cov ntawv, cov ntawv ci, hmoov, strips thiab filaments. Nyob rau hauv huab cua ntub, nws tuaj yeem tsim ib txheej ntawm oxide zaj duab xis los tiv thaiv hlau corrosion. Cov hmoov txhuas tuaj yeem kub hnyiab tau thaum cua sov hauv huab cua thiab emit ib tug dazzling dawb nplaim taws. Nws yog soluble hauv dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide thiab potassium hydroxide tov, tab sis insoluble hauv dej. Cov txheeb ze ntom ntom 2.70. Melting point 660 ℃. Kub taw tes 2467 ℃. Aluminium yog qhov thib peb tshaj plaws hlau nyob rau hauv lub ntiaj teb crust, tom qab oxygen thiab silicon.
Aluminium yog silvery-dawb lub teeb hlau. Nws muaj ductility. Nws yog feem ntau ua rau hauv kab, pas nrig, nplooj ntawv, foils, hmoov, strips thiab filaments.
Nws yog dav siv rau nws cov lightness, zoo hluav taws xob thiab thermal conductivity, siab reflectivity thiab kuj rau oxidation.
Kev siv cov tshuaj nyob ntawm qhov loj ntawm cov khoom ntawm cov khoom. Vim nws cov khoom zoo heev, aluminium muaj ntau yam kev siv.
Aluminium thiab aluminium alloys yog ib qho ntawm cov khoom siv nyiaj txiag tshaj plaws rau ntau yam kev siv. Txij li thaum xyoo 1956, lub ntiaj teb aluminium ntau lawm yog cov hlau tsis muaj hlau, tshaj tooj liab ntau lawm. Tam sim no, ntau lawm thiab ntau npaum ntawm txhuas (nyob rau hauv cov nqe lus ntawm tons) yog thib ob tsuas yog rau hlau, ua tus thib ob loj tshaj plaws hlau siv los ntawm tib neeg; Tsis tas li ntawd, cov peev txheej ntawm txhuas muaj ntau heev, thiab raws li kev suav ua ntej, cov ntxhia tshwj xeeb ntawm aluminium account rau ntau tshaj 8% ntawm cov khoom tsim los ntawm lub ntiaj teb crust.
Lub teeb yuag thiab corrosion kuj ntawm txhuas yog ob qho zoo heev ntawm nws cov kev ua tau zoo.
Qhov ceev ntawm txhuas yog tsawg heev, tsuas yog 2.7 g / cm³. Txawm hais tias nws yog mos, nws tuaj yeem ua rau ntau yam aluminium alloys, xws li tawv txhuas, super tawv aluminium, xeb-pov thawj aluminium, cam khwb cia txhuas, thiab lwm yam. tsheb ciav hlau thiab nkoj. Tsis tas li ntawd, ib tug loj npaum li cas ntawm txhuas thiab nws cov txhuas alloys kuj siv nyob rau hauv qhov chaw foob pob hluav taws, chaw shuttles thiab dag satellites. Piv txwv li, lub dav hlau supersonic muaj li ntawm 70% ntawm txhuas thiab nws cov txhuas alloys. Aluminium kuj tseem siv dav hauv kev tsim kho nkoj, thiab tus nqi ntawm txhuas siv hauv lub nkoj loj thauj neeg feem ntau mus txog ntau txhiab tons.
Aluminium yog qhov thib ob tsuas yog nyiaj, tooj liab thiab kub hauv cov khoom siv hluav taws xob, txawm hais tias nws cov conductivity tsuas yog 2/3 ntawm tooj liab, tab sis qhov ceev tsuas yog 1/3 ntawm tooj liab, yog li kev sib kis ntawm tib qhov hluav taws xob, qhov zoo ntawm txhuas hlau. tsuas yog ib nrab ntawm tooj liab hlau. Aluminium nto oxide zaj duab xis tsis tsuas yog muaj peev xwm tiv taus corrosion, tab sis kuj muaj qee qhov kev rwb thaiv tsev, yog li txhuas hauv kev lag luam hluav taws xob, kev lag luam hlau thiab cable thiab xov tooj cua kev lag luam muaj ntau yam kev siv.
Aluminium yog cov khoom siv hluav taws xob zoo ntawm cov cua sov, nws cov thermal conductivity yog peb zaug ntau dua li cov hlau, yog li txhuas tuaj yeem siv rau hauv kev lag luam los tsim ntau yam khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom ua noj.
Aluminium muaj ductility zoo (nws ductility yog thib ob tsuas yog kub thiab nyiaj), nyob rau hauv 100 ℃ ~ 150 ℃ tuaj yeem ua los ntawm nyias dua 0.01 hli txhuas ntawv nyiaj. Cov aluminium foils no tau dav siv rau ntim luam yeeb, khoom qab zib, thiab lwm yam. Lawv tuaj yeem ua rau txhuas hlau thiab txhuas strips, thiab tuaj yeem dov rau hauv ntau yam khoom txhuas.
Qhov saum npoo ntawm aluminium tsis yooj yim rau corroded vim yog tuab oxide tiv thaiv zaj duab xis, thiab feem ntau yog siv los tsim cov tshuaj reactors, kho mob, khoom siv tub yees, roj av refining li, roj thiab roj pipelines, thiab lwm yam.
Aluminium hmoov muaj ib tug silver-dawb luster (cov xim ntawm hlau feem ntau yog dub thaum nyob rau hauv cov hmoov), thiab feem ntau yog siv los ua coatings, feem ntau hu ua nyiaj hmoov thiab nyiaj xim xim, los tiv thaiv cov khoom hlau los ntawm corrosion, thiab yog zoo nkauj.
Aluminium burning nyob rau hauv oxygen tuaj yeem tawm ntau lub tshav kub thiab lub teeb ci ntsa iab, feem ntau siv los ua cov khoom tawg, xws li ammonium aluminium explosives (los ntawm ammonium nitrate, charcoal hmoov, txhuas hmoov, soot dub thiab lwm yam combustible organic sib tov), combustion mixtures (xws li cov foob pob thiab lub plhaub ua nrog txhuas thermite tuaj yeem siv los tua cov hom phiaj nyuaj rau ntes hluav taws lossis tso tsheb hlau luam, artillery, thiab lwm yam) thiab teeb pom kev zoo sib xyaw (xws li muaj barium nitrate 68%, aluminium hmoov 28%, wormwood 4%) .
Aluminium thermite feem ntau yog siv los yaj cov hlau refractory thiab vuam ntsia hlau, thiab lwm yam.. Aluminium kuj tseem siv los ua deoxidizer hauv cov txheej txheem steelmaking. Aluminium hmoov thiab graphite, titanium dioxide (los yog lwm yam siab melting point hlau oxides) nyob rau hauv ib tug tej yam piv ntawm cov sib tov sib xyaw, coated rau cov hlau, los ntawm kub kub calcination thiab ua los ntawm kub resistant hlau ceramics, nws muaj ib tug tseem ceeb daim ntaub ntawv nyob rau hauv lub foob pob ua ntxaij thiab missile. tshuab.
Cov ntawv txhuas kuj tseem muaj cov khoom zoo ntawm lub teeb pom kev zoo, muaj kev cuam tshuam ultraviolet lub teeb muaj zog dua li cov nyiaj, cov ntshiab aluminium, qhov zoo dua nws lub peev xwm, yog li nws feem ntau siv los tsim cov khoom zoo, xws li lub hnub ci qhov cub reflectors.
Aluminium muaj suab-absorbing zog thiab zoo acoustics, yog li txhuas kuj siv nyob rau hauv broadcasting chav, ceilings nyob rau hauv niaj hnub loj vaj tse, thiab lwm yam. Tsis tshua muaj kub tsis kam, txhuas nyob rau hauv qhov kub thiab txias, nws lub zog es tsis txhob nce tsis muaj brittleness, yog li nws yog zoo tagnrho rau Cov khoom siv hluav taws xob qis, xws li cov tub yees cia, khov cia, Antarctic snow tsheb, cov khoom siv hydrogen oxide ntau lawm.
Raws li kev sib xyaw thiab cov txheej txheem ntawm aluminium: raw aluminium thiab siav aluminium Raw aluminium: muaj pes tsawg leeg: tsawg dua 98% txhuas, nkig thiab tawv, tuaj yeem tig cov khoom siv xuab zeb. Siav txhuas: muaj pes tsawg leeg: ntau tshaj 98% txhuas, mos hauv qhov, tuaj yeem ua calendered lossis dov ntau yam khoom siv.
