Dab tsi yog qhov nta ntawm Aluminium?
Aluminium yog cov khoom hlau thib peb hauv lub ntiaj teb ua kiav txhab, tom qab oxygen thiab silicon. Txoj kev loj hlob ntawm peb cov lag luam loj ntawm aviation, kev tsim kho thiab tsheb, yuav tsum muaj cov ntaub ntawv kom muaj kev tshwj xeeb xws li txhuas los yog txhuas txhuas uas zoo heev pab txhuas hauv kev tsim thiab daim ntawv thov.
Ces dab tsi yog qhov nta ntawm dawb huv txhuas?
1. Kev ceev me me thiab tuaj yeem muaj zog
Ntshiab txhuas ceev yog ze li ntawm 2700kg / m³, li 35% rau qhov ceev ntawm cov hlau. Lub zog ntawm cov ntshiab txhuas muaj peev xwm muab coj los ua kom txias dua. Ntxiv mus, ntxiv hlau ntsiab xws li magnesium, zinc, tooj liab, manganese, silicon, lithium, scandium thiab hais txog, tau txais melting txheej txheem ntxiv zog, nws lub zog yog nyob rau hauv lub nrog zoo zoo hlau alloy.
2. Yooj yim kom ua tiav
Aluminium tau nrum los ntawm txhua txoj kev. Nws cov yas zoo yuav ua rau nws dov mus rau nyias daim hlau thiab ntawv ci, kos rau lub raj, xov xov los sis cov extruded mus rau ntau hom siv pej xeem siv txhuas profiles. Thiab nws yuav tsum tau machined xws li xuas nrig ntaus, milling, tho txawv, npaj, thiab lwm yam ntxiv los ntawm kev siv feem ntau ntawm cov cuab yeej tshuab nrog lub siab ceev tshaj plaws rau kev ua.
3. Los tiv thaiv corrosion thiab hluav taws xob hluav taws xob thiab hluav taws xob conductivity
Qhov nplaum ntawm txhuas yog ib qho yooj yim los ua kom muaj kev kaw thiab yees tiv thaiv lub npe hu ua Al2O3.This cov yeeb yaj kiab tiv thaiv tau tsuas yog pov tseg nyob rau hauv qhov loj tshaj teeb meem ntawm halogen ion los yog alkaline ion. Yog li, aluminium muaj cov khoom zoo ntawm cov tshuaj tiv thaiv atmospheric (nrog rau cov chaw muaj cua thiab dej hiav txwv) kev txhuam thiab dej khov dej. Kev siv txoj kev tiv thaiv zoo tuaj yeem ua rau kom nws cov khoom los tiv thaiv corrosion. Lub fais fab thiab kub conductivity ntawm txhuas yog zoo, tsuas yog tom qab hlau nyiaj, tooj liab thiab kub.
4. Tsis tshua muaj siab tus brittleness tsis muaj
Hauv qhov ntsuas kub hauv zero zero centigrade, lub zog zoo ntawm aluminium yuav tsum nce ntau dua tsis poob.
5. Zoo-zoo thiab muaj zog rau kev xav txog
Qhov piv ntawm qhov xav tau ntawm txhuas saum npoo dawb teeb tuaj yeem yog siab tshaj 80%, purity dua, lub siab dua piv txwv. Meanwhile, aluminium muaj zoo reflection zog infrared rays, ultraviolet rays, electromagnetic yoj, kub tawg thiab lwm yam Aluminium thiab aluminium alloy li qaim silver gloss vim nws muaj zog reflection .Nws yuav ua tau ntau dua glossy thiab zog tom qab machining. Nrog kev kho tshuaj anodized thiab cov hmoov coatings, aluminium profiles yuav ua tau rau hauv cov yeeb yuj thiab ci ntsa iab khoom.
