Hlau Ua Npuas Ncauj Taw Qhia
Oct 10, 2023
Hlau ua npuas ncauj yog cov qauv ntawm tes tsim los ntawm cov khoom siv hlau uas muaj cov khoom ntim siab ntawm cov roj uas muaj cov pores. Cov pores tuaj yeem raug kaw (kaw-cell ua npuas ncauj) lossis txuas ua ke (qhib-cell ua npuas ncauj). Cov foams no txawv ntawm lawv qhov porosity siab heev, nrog rau qhov chaw tsis muaj qhov suav nrog 75-95% ntawm qhov ntim.
Lub zog ntawm cov khoom muaj nuj nqis yog sib npaug rau nws qhov ntom ntom: ib qho 20% tuab cov khoom siv ntau tshaj li ob zaug kom muaj zog li 10% tuab cov khoom siv. Cov hlau nplaum feem ntau khaws qee yam ntawm lawv cov khoom siv lub cev. Tsis yog-flammable hlau ua npuas ncauj yuav nyob twj ywm tsis-flammable, thiab cov npuas dej feem ntau recyclable rov qab mus rau nws cov khoom qub. Thermal conductivity yuav raug txo kom tsawg thaum lub coefficient ntawm thermal expansion tseem nyob tas li.
