Qhov zoo thiab cov khoom ntawm Aluminium Foam

Txoj kev loj hlob ntawm cov txheej txheem niaj hnub no tau ua rau muaj kev txhim kho ntau ntxiv ntawm kev npaj cov tshuab ua npuas dej thiab txo qis ntawm cov nqi tsim khoom. Ua npuas ncauj hlau sawv cev los ntawmaluminium ua npuas ncaujyog ib yam tshiab ntawm cov khoom siv ua haujlwm uas tau tsim kho sai hauv xyoo tas los no. Raws li cov khoom siv, nws yog tus cwj pwm los ntawm lub teeb yuag thiab lub zog tshwj xeeb. Raws li cov khoom siv ua haujlwm, aluminium ua npuas ncauj muaj qhov zoo ntawm kev poob siab, kev poob siab absorbing peev xwm, kub tsis kam, suab rwb thaiv tsev thiab suab nqus.

Internal pores ntawmkaw-cell aluminium ua npuas ncaujmuaj cov pa roj uas muaj lub peev xwm hloov hluav taws xob me me, ua rau nws lub peev xwm hloov hluav taws xob ntau me dua li cov khoom siv. Qhov loj tshwj xeeb thaj chaw, siab porosity, dav tshav kub diffusion qhov chaw thiab siab kub hloov ntawm lub pore phab ntsa ntawm los ntawm-cell ua npuas ncauj aluminium muab nws zoo tshav kub pauv kev ua tau zoo. Nyob rau hauv cov xwm txheej ntawm ntuj convection, kev sib pauv cua sov tuaj yeem nqa tawm los ntawm kev ntws ntawm cov pa los yog kua hauv qhov pores ntawm cov hlau ua npuas dej xws li los ntawm lub qhov txhuas ua npuas ncauj thiab nws cov phab ntsa pore, yog li los ntawm lub qhov txhuas ua npuas dej yog qhov sib pauv zoo heev. cov khoom siv los yog cov khoom siv cua sov dissipation.

Aluminium ua npuas ncauj nyob rau hauv cov txheej txheem compression yuav hloov mus rau hauv ib tug loj tus naj npawb ntawm kev ua hauj lwm nyob rau hauv daim ntawv ntawm txhuas ua npuas ncauj cell deformation, lub cev qhuav dej, rupture thiab kev sib nrig sib txhuam thiab lwm yam ntaub ntawv ntawm lub zog poob, yog li cov npuas dej yuav nqus tau ib tug loj tus naj npawb ntawm sab nraud cuam tshuam lub zog.Aluminium ua npuas ncaujmuaj cov yam ntxwv damping siab, ntshiab txhuas ua npuas ncauj damping tus nqi yog li 5 mus rau 10 npaug ntawm txhuas. Siv lub zog nqus thiab damping zog ntawm txhuas ua npuas ncauj, nws tuaj yeem ua rau cov khoom siv hluav taws xob zoo heev thiab cov khoom siv vibration damping, xws li tsheb bumpers, spacecraft landing gear, elevators, conveyor kev nyab xeeb pads thiab high-speed grinder shield zog-absorbing liner. .

Vim muaj cov dej sib kis tau zoo, qhov kev ua tau zoo ntawm lub qhov hluav taws xob ntawm lub qhov ua npuas dej tuaj yeem ncav cuag lub thermal conductivity ntawm nws cov matrix ntom, thiab kev siv cov hlau ua npuas dej no tuaj yeem txhim kho lub peev xwm ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hauv aerospace, compact heat sinks rau lub zog lub zog, thiab condensation yees rau cua txias. Piv txwv li, rau cov khoom siv los tiv thaiv icing thiab tiv thaiv khov siv rau hauv dav hlau,hla-qhov aluminium ua npuas ncauj panelsyog ntsia rau pem hauv ntej ntawm lub tis, thiab rhuab roj los yog antifreeze tuaj yeem txau tawm ntawm aluminium npuas panels kom ua tiav lub hom phiaj ntawm kev tiv thaiv icing.
