Hlau ua npuas ncauj, ua ib yam khoom tshiab, muaj ntau yam kev siv. Vim nws tus yam ntxwv, nws tsis tsuas yog muaj compression kuj zoo heev, tab sis kuj muaj zoo heev plasticity thiab additivity; tam sim no, nws kuj tau dav siv nyob rau hauv aerospace thiab tub rog teb, thiab raws li ib yam ntawm cov khoom siv hnyav, nws kuj yog dav siv nyob rau hauv ntau yam kev lag luam teb.

Aluminium ua npuas ncauj yog ib qho khoom siv zoo heev uas tau txais kev pom zoo los ntawm ntau qhov kev lag luam vim nws cov khoom tshwj xeeb. Nws yog ib qho khoom sib sib zog nqus ntxeem tau tsim los ntawm cov khoom txhuas nrog ntau qhov sib cuam tshuam qhov pores. Cov khoom siv tshiab no ua ke nrog lub zog, durability thiab versatility, ua rau nws zoo tagnrho rau ntau yam kev siv.

Nyob rau hauv lub ntiaj teb no ntawm suab-absorbing cov ntaub ntawv, txhuas ua npuas ncauj yog ua nthwv dej raws li ib tug revolutionary khoom. Nrog nws cov khoom tshwj xeeb thiab ntau yam, aluminium ua npuas ncauj yog paving txoj hauv kev rau kev txhim kho cov khoom ntxeem tau suab-absorbing uas yog redefining kev lag luam.

Kev txo qis ntawm fossil fuels thiab kev txhawj xeeb loj zuj zus txog lub zog thiab ib puag ncig teeb meem tau ua rau muaj kev tshawb fawb dav dav los tsim cov khoom siv hluav taws xob. Electrochemical electrolysis ntawm dej yog suav hais tias yog ib lub tswv yim zoo rau kev tsim cov roj hydrogen.

Nyob rau hauv ib lub sijhawm ntawm kev sib txuas lus wireless thiab electromagnetic pollution ntau zuj zus, qhov kev xav tau ntawm cov khoom siv hluav taws xob electromagnetic yoj absorbing tau dhau los ua qhov tseem ceeb dua li yav tas los. Hlau ua npuas ncauj, raws li cov khoom siv tshiab, qhia tau hais tias muaj peev xwm zoo hauv daim teb no. Kev tshawb fawb tsis ntev los no tau tsom mus rau kev tshawb nrhiav lub zog ntawm electromagnetic yoj nqus ntawm cov hlau foams, thiab cov txiaj ntsig tau zoo heev.

Nyob rau hauv niaj hnub haiv neeg, peb sab laj lub suab barrier cov khoom no yog ntau thiab ntau, rhiav, tsev kho mob, tsev kawm ntawv, txoj kev loj kev tswj chaw ua hauj lwm, thiab thiaj li nyob rau hauv kev xav tau ntawm lub suab nrov txo, nyob rau hauv tus txheej txheem ntawm kev sab laj nws, feem ntau nug ib lo lus nug yog: yuav ua li cas. ntau qhov no tuaj yeem txo tau. Tam sim no peb yuav qhia rau koj txog lub hauv paus ntsiab lus ntawm kev txo suab nrov ntawm lub suab barrier.

Aluminium ua npuas ncauj yog cov khoom siv ua haujlwm siab, uas yog siv dav hauv kev tsim tsheb, kho kom zoo nkauj hauv tsev thiab lwm yam haujlwm. Txhawm rau tsim cov txhuas ua npuas dej, koj yuav tsum siv cov khoom siv ntau, suav nrog kev ua, foaming, ziab thiab lwm yam txheej txheem. Thaum siv cov khoom siv no, ua tib zoo saib xyuas kev nyab xeeb, kho thiab tswj cov khoom siv raws li cov lus qhia kom paub tseeb tias qhov ua tau zoo thiab ua haujlwm ntawm txhuas ua npuas ncauj.

Aluminium ua npuas ncauj zoo ib yam li daim txhuam cev thiab yog lub npe hu ua universal hlau, nrog ib tug tsawg ntom thiab lub teeb yuag, siv raws li ib tug tiv thaiv txheej rau qhov chaw tsheb, resistant rau compression thiab muaj peev xwm tiv taus hluav taws xob vim hluav taws xob impulses. Nws yog cov khoom siv hlau tshiab ua los ntawm foamed aluminium alloy.

Raws li dav siv zog-absorbing cov ntaub ntawv tiv thaiv, daim ntawv thov ntawm aluminium foam sandwich (AFS) panels tseem txwv los ntawm lub inherently tsawg mechanical zog ntawm cov tub ntxhais ua npuas ncauj. Kev koom ua ke ntawm coppercoated carbon fibers (Cf) tau ua pov thawj tias muaj txiaj ntsig zoo hauv kev txhim kho cov khoom siv ntawm txhuas ua npuas ncauj.

Txawm li cas los xij, kev nkag siab ntawm nws cov txheej txheem foaming thiab microstructure tseem txwv. Hauv kev ua haujlwm no, AFS thiab Cf / AFS tau tsim los ntawm kev ntim cov hmoov hlau metallurgy. Tus cwj pwm foaming ntawm AFS thiab Cf / AFS thaum kub siab yog nyob rau hauv situ pom siv synchrotron hluav taws xob X-ray imaging technology los soj ntsuam cov nyhuv ntawm Cf ntawm npuas nucleation, kev loj hlob, thiab ua npuas ncauj stability. Tsis tas li ntawd, macroscopic pore loj faib, microscopic microstructure, thiab compressive mechanical zog ntawm AFS thiab Cf / AFS tau soj ntsuam. Cov txiaj ntsig tau pom tias qhov muaj nyob ntawm Cf ua rau muaj txiaj ntsig zoo ntawm cov nucleation, txhim kho cov foaming stability, thiab tiv thaiv kev tsim ntawm cov npuas loj hauv zos thaum lub sij hawm ntxov nucleation thiab kev loj hlob. Lub caij no, Cf/AFS nthuav tawm cov pore diameters zoo dua thiab tsawg dua pore tsis xws li AFS. Kev faib tawm ntawm Cf nrog zoo wettability raws lub pore phab ntsa tiv thaiv kua zaj duab xis rupture thiab txo coalescence. Qhov kev sim compression qhia tau hais tias, piv rau AFS, lub zog compressive thiab lub zog nqus ntawm Cf / AFS tau nce li ntawm 40.6% thiab 84.8%, feem.

Aluminium ua npuas ncauj sandwich panels tau dhau los ua neeg nyiam nyob hauv ntau qhov kev lag luam vim lawv cov khoom tshwj xeeb thiab ntau yam kev siv. Cov vaj huam sib luag no muaj cov khoom siv sib sib zog nqus (xws li txhuas ua npuas ncauj) sandwiched ntawm ob daim ntawv nyias nyias. Qhov kev tsim kho tshiab no ua rau cov khoom siv tsis yog tsuas yog hnav, tab sis kuj muaj zog, ruaj thiab corrosion-resistant. Hauv qhov blog no, peb yuav ua tib zoo saib ntawm kev siv thiab cov txiaj ntsig ntawm aluminium foam sandwich panels, thiab lawv qhov cuam tshuam rau kev lag luam sib txawv.
