Hauv kev lag luam automotive, aluminium ua npuas ncauj tsuas yog siv rau kev poob siab-ua haujlwm buffering ntawm lub tsheb lub cev thiab txo suab nrov thiab rwb thaiv tsev ntawm lub tsheb lub cev thiab cov phab ntsa.
Los ntawm-cell hlau ua npuas ncauj yog ib qho tshwj xeeb ua tiav high-permeability ntxeem tau cov ntaub ntawv nrog ib tug sponge zoo li ntxeem tau qauv los ntawm sab hauv tawm. Kev nkag ntawm lub suab los ntawm qhov chaw mus rau hauv nws sab hauv ua rau cov me me fibers ntawm huab cua thiab cov khoom nyob rau hauv lub pores kom vibrate, thiab los ntawm kev sib txhuam thiab viscous kuj, lub suab lub zog yog hloov dua siab tshiab rau hauv tshav kub zog thiab absorbed.

Piv nrog rau lwm cov ntaub ntawv suab-absorbing, cov ntaub ntawv hlau foamed muaj suab nrov-absorbing yam ntxwv nyob rau hauv tsawg zaus. Raws li qhov kev xaiv ntawm lub thickness ntawm huab cua txheej, nws qhia tau hais tias zoo heev suab-absorbing nyhuv thaum nws koom nrog ib tug ntau yam ntawm low-frequency teb.
Nws yog siv rau lub suab nqus ntawm lub tsheb thiab lub tsheb ciav hlau qhov chaw, tsis yog tsuas yog muaj suab nrov zoo, tab sis kuj muaj kev ua haujlwm zoo dua los tiv thaiv deformation dua li cov ntaub ntawv polyester, muaj lub zog nqus dej zoo, lub zog siab, tsis muaj combustion, thiab ua kom muaj kev nyab xeeb. ntawm cov khoom siv thauj khoom; Nyob rau tib lub sijhawm, cov khoom siv hlau tsis muaj tshuaj lom thiab tsis muaj kev puas tsuaj, uas yog ntau dua raws li kev tiv thaiv ib puag ncig.
Tam sim no, cov ntaub ntawv hlau foamed tau siv dav hauv cov khoom siv hluav taws xob zoo rau tsheb thiab tsheb ciav hlau hauv txawv teb chaws.
