Aerogel cube block with high permeability and high porosity Nanoporous silica
Silica aerogel Aerogel is composed of nano colloidal particles or polymer molecules that coalesce to form nano porous Low density three-dimensional nanoporous solid with network structure and filled with gaseous medium in the pores State materials. Frozen cigarettes . The density of this material is only 3.55 kilograms per cubic meter, which is only 2.75 times the density of air There are excellent characteristics in fields such as acoustics, optics, mechanics, etc. The nano pore size of aerogel is less than 69 nm of the average free path of air molecules, so it can show To reduce the degree of thermal conduction and convection of gas molecules, while increasing their fine three-dimensional network structure By establishing pathways for solid heat transfer and radiation, the heat transfer efficiency is reduced. Product parameters Product name: silica aerogel block Color: Light Blue Thermal conductivity: 0.012-0.016 W/m.K Specific surface area: ≥ 400m2/g Porosity:>90% Density: 50-90kg/m ³ Aperture: 20-40nm Temperature resistance: ≤ 800 common problem: Q1. Is the aerogel block brittle? The aerogel blocks in our shop are fragile and can be crushed by hand. The shipment will be boxed, so you don’t have to worry about it breaking during transportation. If you want to keep the product intact after receiving it, please store it properly and do not crush it. Q2. Does the aerogel block support customization? Support size customization, please contact customer service for specific requirements.
