PRODUCTION OF NEW TYPE INSULATION MATERIAL: EXPANDED PERLITE-SILICA AEROGEL COMPOSITE

نویسندگان

چکیده

Silica aerogel is a class of nanoporous material with extremely high porosity (85–99.9 %) and specific surface area (500–1200 m2/g), as in cause very low density, thermal conductivity. But silica have some disadvantages. One this disadvantages cost. In study, to solve problem has been used cost precursor which rice husk ash. Also, we try improve porosity. To the expanded perlite (EP). produced EP heated 760–1100 °C, at point its native water converted vapor caused expand 4–20 times original volume, then high-porosity lightweight aggregates are formed. study aerogels reinforced product new type composite building insulation material. The prepared EP-silica was characterized using SEM BET measurements.

Thermal Properties of Advanced Aerogel Insulation

Buildings consume too much energy. For example, 16.6% of all the energy used in the United States goes towards just the heating and cooling of buildings. Many governments, organizations, and companies are setting very ambitious goals to reduce their energy use over the next few years. Because the time periods for these goals are much less than the average lifetime of a building, existing buildi...

Optimization of Biodiesel Production Using Immobilized Candida Rugosa Lipase on Magnetic Fe3O4-Silica Aerogel

Hydrophobic magnetic silica aerogel was used as a support to immobilize Candida rugosa lipase by adsorption method. Physical and chemical properties of the support and immobilized lipase were determined by Field Emission Scanning Electron Microscope (FESEM), Brunauer–Emmett–Teller (BET) analysis and Fourier Transform InfraRed (FT-IR) spectroscopy and the results showed that the lipase was s...
