Hlau Foams tsis yog cov hlau uas nyuaj tshaj plaws thiab muaj ntau yam zoo heev

Hlau Foam Txheej txheem cej luam
Hlau ua npuas ncaujyog cov ntaub ntawv uas muaj honeycomb khaubncaws sab nraud povtseg ntawm metallic lug nrog ib tug tej yam degree ntawm porosity uas yog lub teeb yuag, muaj zog absorbing, thermally thiab hluav taws xob conductive. Hlau Foams tuaj yeem hloov kho rau cov hlau siv, kev ua, thiab cov qauv pore, uas ua rau cov khoom sib txawv thiab ntau yam kev siv nrog cov kev xav tau sib txawv.

Hlau Ua Npuas Ncauj Hardness
Cov hlau ua npuas dej tsis yog cov hlau uas nyuaj tshaj plaws; lawv hardness yuav txawv nyob ntawm seb cov hlau muaj pes tsawg leeg thiab pore qauv. Piv txwv li, tungsten ua npuas ncauj tuaj yeem ncav cuag Vickers hardness ntawm 600, thaum txhuas ua npuas ncauj yog qhov qis ntawm qhov hardness nplai, feem ntau nyob ib ncig ntawm HV50. Nyob rau hauv sib piv, superhard pob zeb diamonds synthesized ntawm high pressures thiab kub yuav ncav cuag ib tug Vickers hardness txog 5,000, uas yog ntau tshaj kaum npaug ntawm hardness ntawm hlau foams.

Cov khoom zoo heev ntawm cov hlau ua npuas ncauj
Txawm hais tias hlau ua npuas ncauj tsis yog qhov nyuaj tshaj plaws, nws tseem muaj ntau yam khoom zoo heev. Piv txwv li:
1, lub teeb ci ntsa iab: vim nws cov qauv pore cov qauv, cov kav hlau muaj qhov tsis tshua muaj zog, feem ntau tsawg dua 0.5 g / cm3, yog li nws tuaj yeem siv ua alub teeb yuag khoom sivhauv aerospace thiab automotive applications.
2 、 Lub zog nqus dej ntau: Cov qauv pore ntawm cov hlau ua npuas dej tso cai rau nws deform thiab nqus lub zog thaum raug lub zog, yog li nws muaj peev xwm tiv thaiv kev vibration thiab kev sib tsoo zoo heev.
3, thermal thiab hluav taws xob khoom: hlau ua npuas ncauj yuav siv tau raws li ib tug zoo thermal rwb thaiv tsev thiab thermal conductivity khoom, tab sis kuj muaj zoo hluav taws xob conductivity.

Vim yog cov khoom zoo tshaj plaws saum toj no,hlau ua npuas ncaujmuaj ntau yam ntawm daim ntawv thov kev cia siab, xws li rau tsheb poob siab absorbing cov ntaub ntawv, aerospace structural Cheebtsam, mos mos cov ntaub ntawv, tshuaj reactors, thiab lwm yam teb.
