1. Dab tsi yog Foamed Hlau thiab Foamed Aluminium
Nyob rau hauv cov chav kawm ntawm keeb kwm, qhov kev tshawb pom ntawm foamed hlau yog ib qho tseem ceeb nyob rau hauv lub kiv puag ncig ntawm tag nrho cov teb ntawm cov ntaub ntawv engineering. Hlau ua npuas ncauj yog cov khoom siv uas muaj cov qauv hlau uas muaj ntau qhov pores uas muaj cov pa roj raws li cov qauv. Lub qhov hws ntawm cov hlau ua npuas dej tuaj yeem yog nyob rau hauv daim ntawv ntawm kev sib tshuam los yog hermetic seals, hu ua open-cell thiab kaw-cell foams, feem. Ntawm lawv,aluminium ua npuas ncaujyog tam sim no cov hlau ua npuas ncauj nrog lub peev xwm loj tshaj plaws rau daim ntawv thov, thiab lub npe hu ua "lub hnub qub hlau" vim muaj cov khoom zoo heev, xws li cov porosity siab, tsis tshua muaj ntom, lub teeb yuag, siab zog, zoo compression, zoo cuam tshuam, zoo suab haum, thiab electromagnetic shielding. "hlau hnub qub", dav siv nyob rau hauv aerospace engineering, manufacturing thiab lwm yam kev ua nyob rau hauv lub teb ntawm lub cev sciences.

2. Khoom thiab kev siv ntawmAluminium Foam
Aluminium ua npuas ncauj yog cov hlau uas muaj cov porosity siab thiab cov qauv ntxeem tau, nyob rau hauv uas lub kaw qhov pores account rau li peb lub hlis twg ntawm tag nrho cov ntim ntawm cov khoom hlau, ua rau cov khoom siv lub teeb heev. Ntxiv nrog rau cov khoom no, txhuas ua npuas ncauj muaj lub zog nqus tau zoo thiab siab compressibility. Hais txog qhov ntom ntom, cov kws tshawb fawb pom tias feem ntau cov qauv txhuas ua npuas ncauj muaj qhov ntom ntom ntawm 0.4-1.2 g-cm-3. Tsis tas li ntawd, aluminium ua npuas ncauj yog suab-absorbing, recyclable thiab muaj thermal conductivity tsawg.

Raws li cov ntawv thov muaj kev txhawj xeeb, electromagnetic shielding, lub teeb yuag thiab nqus cov khoom ntawm txhuas ua npuas ncauj ua rau nws yog tus neeg sib tw zoo tshaj plaws rau cov khoom siv hauv kev tswj fusion, automotive, aerospace thiab kev lag luam vim nws muaj peev xwm tiv taus huab cua puag ncig. Hauv kev tswj cov khoom siv fusion, kaw cov xov tooj ntawm tes aluminium ua npuas ncauj yog cov khoom siv hluav taws xob zoo heev. Vim qhov kev sib tshuam ntawm cov pob txha ua npuas ncauj aluminium, uas muaj qhov loj me ntawm thaj chaw tshwj xeeb thiab muaj peev xwm zoo nqus thiab cuam tshuam cov hluav taws xob tsis zoo, ntau yam kev poob, xws li kev poob siab thiab kev xav tsis zoo, tshwm sim hauv aluminium npuas, uas muab cov kev sib txuas ntawm cov hlau nplaum. ua npuas ncauj aluminium zoo heev electromagnetic shielding zog. Thiab nws kuj tau pom tias electromagnetic shielding efficiency ntawm txhuas ua npuas ncauj yog txo thiab tom qab ntawd nce nrog qhov nce ntawm electromagnetic yoj zaus. Hauv kev lag luam aerospace, txhuas ua npuas ncauj yog siv los ua ib qho khoom siv hauv kev tsim cov chaw cones lossis turbines, uas yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev txo qis tag nrho qhov hnyav ntawm cov khoom siv dav hlau vim qhov tsawg ntawm txhuas ua npuas ncauj. Tsis tas li ntawd, raws li cov khoom siv hluav taws xob zoo heev, txhuas ua npuas dej yog siv rau hauv kev tsim cov khoom siv dav hlau buffers, kev vibration absorbers thiab hauv qab ntawm lub dav hlau rov qab capsules, uas ua rau muaj kev nyab xeeb tsaws thiab tiv thaiv cov neeg caij nkoj thiab cov khoom siv chaw. Los ntawm kev nqus lub zog thiab ua kom muaj kev vibrations zoo, aluminium ua npuas ncauj tuaj yeem ua kom muaj kev nyab xeeb ntawm cov neeg caij nkoj thaum muaj kev cuam tshuam ntawm lub dav hlau tsaws.
Hauv kev lag luam automotive, aluminium ua npuas ncauj pab txo tag nrho cov khoom siv hauv cov thav duab, ua kom cov txheej txheem sib dhos ua haujlwm tau zoo, uas thaum kawg yuav pab txo cov nqi thiab txhim kho kev ua haujlwm. Tam sim no, txhuas ua npuas ncauj yog siv rau hauv cov khoom sib tsoo, cov neeg hla kev thiab cov kab hluav taws xob qhov rooj hauv tsheb lub cev qauv ntawm kev ua lag luam.
