Ua npuas ncauj hlau yog ib yam khoom tshiab. Txawm hais tias nws tau siv dav hauv kev lag luam tub rog thiab roj teeb, nws daim ntawv thov dav hauv lwm qhov kev lag luam nyuam qhuav pib, thiab tib neeg tseem tsis muaj kev nkag siab tob txog nws. Nov yog cov ntsiab lus luv luv ntawm cov yam ntxwv ntawm cov hlau ua npuas ncauj:

Vim yog cov qauv tshwj xeeb ntawm cov hlau ua npuas ncauj, nws muaj ntau yam zoo heev uas txawv ntawm cov khoom siv ib txwm muaj, xws li:

1. Siab heevh porosity: yuav luag tag nrho permeable qauv nrog ib tug los ntawm porosity ntawm ntau tshaj 98%. Raws li cov khoom siv lim, nws muaj qhov siab me me thiab qhov siab ntws;
2. Cov cheeb tsam loj tshwj xeeb: nyob rau hauv tib qhov los ntawm qhov tus nqi, nws muaj qhov loj tshaj plaws ntawm thaj chaw tshwj xeeb piv nrog rau lwm cov khoom ntxeem tau;
3. High porosity thiab uniform pore qauv: lub porosity nce mus txog ntau tshaj 95%, uas yog ib tug peb-dimensional ntxeem tau thiab pob tshab qauv, thiab muaj zoo hlau zog, tib lub ntim, sib dua cov khoom hnyav, lub siab tshaj plaws kev pab, thiab zoo suab haum, lub zog. absorption thiab electromagnetic shielding zog;
4. hlau khoom: ua npuas ncauj hlau tuaj yeem ua los ntawm npib tsib xee, tooj liab, hlau lossis hlau cov ntaub ntawv. Cov substrates sib txawv muaj cov khoom siv hlau sib txawv, xws li kev tiv thaiv hluav taws, tsis muaj tshuaj lom, tsis muaj qhov poob qis, rov ua dua tshiab, thermal conduction, thiab lwm yam, thiab muaj cov ntawv thov dav.
5. Nws tuaj yeem welded, sheared, thinned, dov thiab lwm yam kev ua haujlwm. Nyob rau tib lub sijhawm, cov khoom siv hlau tuaj yeem rov ua dua tshiab, uas ua rau muaj kev tiv thaiv ib puag ncig thiab txuag nqi.
