Hlau ua npuas ncauj muaj cov khoom zoo heev: siab porosity, qhov loj ntawm qhov chaw, lub zog tshwj xeeb, siab nruj, lub zog nqus, zoo damping thiab poob siab absorbing, corrosion kuj, kub tsis kam, electromagnetic shielding, non-toxic, yooj yim ua. , tuaj yeem pleev xim rau saum npoo, thiab lwm yam.. Vim nws lub cev zoo heev thiab cov khoom siv kho tshuab, cov hlau ua npuas dej tuaj yeem siv los ua cov khoom siv thiab cov khoom siv. Feem ntau, nws muaj ob qho tib si kev ua haujlwm thiab cov qauv tsim, thiab yog cov khoom siv ua haujlwm ntau yam nrog kev ua tau zoo heev uas sib xyaw ua haujlwm thiab cov qauv. Foam hlau yog dav siv nyob rau hauv aerospace, hluav taws xob kev sib txuas lus, kev thauj mus los, atomic zog, tshuaj, ib puag ncig tiv thaiv, metallurgy, machinery, kev tsim kho, electrochemistry thiab petrochemical kev lag luam.

Qhov sib txawv tseem ceeb ntawm cov hlau ua npuas ncauj thiab cov khoom siv tsoos yog lawv cov microstructure sib txawv heev, uas tuaj yeem maj mam txo los ntawm millimeter mus rau micron lossis txawm nanometer loj thaum tswj cov porosity siab. Yog li ntawd, cov hlau ntxeem tau muaj qhov tsim tau zoo thiab tuaj yeem tsim nrog kev ua kom zoo dua qub thiab muaj ntau yam kev sib koom ua ke tsim ntawm lawv cov microstructure ua ntej npaj raws li qhov xav tau ntawm kev siv sib txawv.
Lub teeb yuag, kev siv hluav taws xob tsawg thiab kev nyab xeeb thiab kev nplij siab yog txoj kev loj hlob ntawm lub tsheb, thiab kev txhim kho cov qauv ntawm lub tsheb yog txoj hauv kev kom txo tau qhov hnyav thiab txhim kho cov roj efficiency, tab sis nws yog ib qho nyuaj rau ntxiv txo qhov chaw ntawm lub tsev. Kev siv cov cav me me lossis lwm yam kev txo qis yuav ua rau muaj teeb meem xws li lub cav cua sov dissipation, thiab kev nyab xeeb ntawm kev sib tsoo vim lub cev ua haujlwm luv. Qhov yuav tsum tau txo cov suab nrov ntawm lub tsheb ua rau qhov xav tau cov khoom siv suab nrov tshiab, yog li kev siv cov khoom siv sib xyaw ua ke rau cov khoom siv tsheb muab cov kev daws teeb meem zoo rau cov teeb meem no. Hauv kev lag luam automotive, qhov twg tus nqi thiab cov ntaub ntawv zoo yog qhov xav tau heev, kev siv cov txhuas ua npuas ncauj tuaj yeem txo qhov loj ntawm lub tsheb, txo cov roj siv thiab kev co, txo lub nra ntawm ib puag ncig, thiab ua kom muaj kev nyab xeeb thiab txhim khu kev qha. kev nplij siab ntawm lub tsheb. Daim ntawv thov ntawm txhuas ua npuas ncauj hauv kev lag luam tsheb feem ntau suav nrog cov qauv hnav, lub zog nqus cov qauv thiab cov qauv hloov hluav taws xob, thiab lwm yam.,
