Aluminium ua npuas ncauj (cov hlau ntxeem tau raws li txhuas thiab nws cov alloys) tau paub ntau tshaj li ib nrab xyoo pua, tab sis tseem muaj kev faib me me thiab daim ntawv thov. Lub ntsiab yog vim li cas rau qhov no yog qhov tsawg reproducibility ntawm cov qauv thiab cov khoom siv nyob rau hauv zus tau tej cov aluminium foams. Txoj kev txhim kho ntawm txhuas ua npuas ncauj tshuab tau ua rau nws muaj peev xwm kov yeej qee qhov teeb meem no. Ntau yam txheej txheem rau kev tsim cov hlau foams tau tsim thiab tshawb xyuas.

Keeb kwm, cov neeg tsim khoom ntawm cov ntaub ntawv no tau tshwm sim los ntawm cov khoom ntxeem tau ntuj xws li ntoo, pob txha, coral, pumice thiab lwm yam ntxhia ntxhia. Cov yam ntxwv ntawm cov ntaub ntawv no yog kev sib xyaw ua ke ntawm lub zog siab, qhov hnyav tshwj xeeb thiab kev nqus zoo zog. Niaj hnub no, manufacturers ntawm aluminium foams tuaj yeem tsim cov hlau nrog cov khoom zoo sib xws kuj yooj yim. Qhov ntau ntawm cov ntawv thov ntawm aluminium foams yog tam sim no dav dua thiab muaj ntau ntau yam kev siv sib txawv.

Cov khoom siv ntau yam nrog cov qauv tsim tsis muaj kev txwv thiab kev siv architectural. Raws li nws qhov tshwj xeeb zoo li, nws muaj lub suab nqus cov khoom ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau ob lub suab nqus thiab kev zoo nkauj. Nws yog siv rau Facades, phab ntsa cladding, qab nthab vuas los yog poob qab nthab, tsev noj mov, tuav, chaw ua hauj lwm, tsev apartment, showroom displays, Terrazzo flooring, signage, teeb pom kev zoo fixtures, exhibits, thiab txhua daim ntawv thov uas koj twv yuav raug hu xav txog.

Aluminium ua npuas ncauj tsim muaj zog tab sis lub teeb yuag panels. Zoo sib xws nyob rau hauv tsos rau ib tug hlau daim txhuam cev, nws yog visually striking, nrog ib tug niaj hnub ua yeeb yam saib. Rau architecture, txhuas ua npuas ncauj yog tsim nyob rau hauv panels xws li nyob rau hauv ntau yam ntom ntom, thiab nyob rau hauv thicknesses ntawm 12.7mm mus rau 43.2 hli (kev cai muaj nyob rau hauv cov khoom yuav tsum tau). Standard versions yog Me, Mid thiab Loj.

Qhov saum npoo ntawm txhua lub vaj huam sib luag yog sab laug nyob rau hauv nws cov khoom ntuj tsim, los yog undergoes nto npaj uas muab ntau yam sib txawv. Qhov tshwm sim raws li cov khoom nto "shimmering" saib mus rau qhov zoo nkauj "dej froth" saib, txawm tias kev cai tsim. Lub 2 sab ntawm txhua lub vaj huam sib luag, txheeb xyuas tias 'saum toj thiab / lossis hauv qab, saib txawv ntawm ib leeg.

Kev tsim ntawm aluminium ua npuas ncauj

Muaj cov txheej txheem sib txawv rau kev tsim cov aluminium foams.

Nyob rau hauv ib rooj plaub, cov hlau ua npuas ncauj yog tau los ntawm cov hlau molten nyob rau hauv ntau txoj kev. Raws li cov aluminium cools thiab hardens, hlau ua npuas ncauj stabilses. Gas ntws los yog tshuab tshuab yog siv los ua npuas dej. Tshuab tshuab decomposes nyob rau hauv tej yam kev mob thiab ua rau cov pa emissions. Cov tshuaj ntxiv tshwj xeeb yog qee zaum siv los ua kom cov pa npuas kom ruaj khov kom cov npuas tsis tawg ua ntej kho. Cov txheej txheem no tuaj yeem siv tau kom tau txais cov ntawv txhuas ua npuas ncauj, cov khoom lag luam nrog cov duab yooj yim thiab txhuas ua npuas ncauj qhaub cij. Cov khoom zoo li no muaj hlau ua npuas ncauj ua lub hauv paus, uas yog npog ntawm ob sab nrog ib txheej ntawm cov khoom txhuas.

Lwm txoj kev yog casting nrog ib tug muab tub lim. Piv txwv li, ntsev nplej tuaj yeem ua cov khoom ntim, uas tom qab ntawd ntxuav tawm ntawm aluminium matrix, thiab pores tshwm es tsis txhob ntsev. Polyurethane ua npuas ncauj nrog kub-resistant txheej kuj yog siv los ua cov khoom ntim, uas kub hnyiab tawm thaum kho cua sov.

Lwm cov txheej txheem ntawm txhuas ua npuas ncauj siv hollow ceramic lossis hlau pob, uas tau muab tso rau hauv cov hlau matrix.

Hauv kev txhaj tshuaj molding, polymer granules tuaj yeem siv los tsim cov pores. Vim lub sijhawm txheej txheem luv luv, cov granules tsis decompose nyob rau hauv lub siab kub. Lawv nyob twj ywm nyob rau hauv cov hlau matrix li fillers los yog raug tshem tawm los ntawm kev kho cua sov ntev. Nyob rau hauv rooj plaub tom kawg, ib qho qhib-pored aluminium ua npuas ncauj tau txais.

Kev tsim cov hlau foams tseem muaj ib qho kev taw qhia, hmoov metallurgy. Ua ntej, sib tov ntawm txhuas hmoov nrog tshwj xeeb additives yog tsim. Thaum xws li ib tug sib tov yog rhuab, ua npuas ncauj thiab sintering txheej txheem tshwm sim uas, tom qab txias, ua rau ntxiv hom ntawm txhuas ua npuas ncauj.

Txoj kev niaj hnub tshaj plaws kom tau txais cov hlau ntxeem tau yog cov cuab yeej siv ntxiv. Nrog kev tsim khoom ntxiv, cov duab thiab 3D qauv ntawm cov khoom tuaj yeem tswj tau qhov tseeb. Txawm li cas los xij, cov txheej txheem no tseem siv nyiaj ntau heev thiab tsuas yog siv tau rau qee qhov tsawg ntawm cov hlau.

Cov cuab yeej thiab kev siv

Kaw-pore aluminium ua npuas ncauj muaj qhov porosity ntawm 80 mus rau 98%. Nws lub zog tseem ceeb tshaj qhov ntawm cov khoom hlau ntawm tib qhov hnyav. Kev siv cov ntaub ntawv zoo li no muaj peev xwm zoo, tshwj xeeb tshaj yog rau kev thauj mus los ntawm kev lag luam tsheb, kev lag luam aerospace thiab nkoj tsim. Kev txo qhov hnyav ua rau kom txuag tau roj los yog ua kom muaj peev xwm nce qhov hnyav ntawm kev thauj mus los.

Cov qauv ntxeem tau ntawm aluminium npuas absorbs lub zog cuam tshuam. Cov cuab yeej no tuaj yeem siv tau thaum thauj mus los los tiv thaiv kev sib tsoo, ua armor thiab tawg tiv thaiv. Hlau ua npuas ncauj dampens suab. Yog li ntawd, aluminium npuas vaj huam sib luag tuaj yeem siv ua lub suab nqus phab ntsa raws txoj kev thiab kev tsheb ciav hlau. Lub suab rwb thaiv tsev ntawm xinesmas thiab cov rooj sib tham hauv tsev kuj tuaj yeem ua haujlwm tau zoo. Vim nws qhov hnyav qis thiab zoo nkauj nto, aluminium npuas yog siv rau sab hauv thiab sab nrauv tsim.
