Cyclopentane / Isopentane (7: 3) foaming: Txhawm rau txo cov nqi tsim khoom ntawm cov tub yees, siv cyclopentane / isopentane tuaj yeem txo qhov molding ntom ntawm cov npuas dej, thaum tswj kev ruaj ntseg siab. Kev suav qhia pom tias qhov ntim ntim rau lub tub yees ntau lawm yog 5% mus rau 8% qis dua nrog cyclopentane foaming, thiab cov tub ntxhais ceev ntawm lub txee yog 33 kg / m³. Lub thermal conductivity ntawm lub tub yees ua npuas ncauj yog nyob nruab nrab ntawm 0.0210 thiab 0.0220 W / m·K, tab sis lub zog noj ntawm lub tub yees yog me ntsis siab dua li ntawm lub cyclopentane system.
Ntawm tib cov kab ntau lawm, foaming tuaj yeem hloov pauv ntawm cyclopentane thiab cyclopentane / isopentane raws li kev txiav txim ntau lawm. Ua ntej hloov, cov khoom siv thiab cov kav dej yuav tsum tau muab ntxuav thiab ntxuav nrog cov khoom siv polyether tshiab los siv ua ntej tus neeg sawv cev tshiab foaming tuaj yeem siv tau.
