6 FAQs about [Expanded perlite energy storage]
How many times can perlite expand?
Perlite can expand 7–16 times over its original volume if heated between 760 °C and 1100 °C , and it is thermal and acoustical insulator. The low density and light weight characteristics of expanded perlite (ExP) makes it one of the best retainer materials suitable for preparing form-stable composite PCMs (F-SCPCMs) for TES purposes , .
What are the properties of expanded perlite?
Expanded perlite has a bulk density of 60–80 kg/m 3 and water absorption of 712.1–816.4%. Low density and fluffy structure make expanded perlite’s low thermal conductivity relatively. EP’s chemical properties are relatively stable for it is mainly composed of SiO 2 and Al 2 O 3 [ 12 ].
What is the difference between EPA and expanded perlite?
In dry condition, the thermal conductivity tests had no obvious difference between the expanded perlite and EPA: expanded perlite’s thermal conductivity is 0.034–0.035 W/m K, while EPA’s thermal conductivity is 0.034–0.035 W/m K, but obvious in the wet condition. Aerogel is a fragile material which is easily broken under a small external force.
Is expanded perlite a form-stable PCM?
Many researchers investigated the form-stable PCMs using expanded perlite as support material. As shown in Table. 3, Dixit et al. prepared by impregnating propyl palmitate in expanded perlite with a maximum PCM load of 55 wt% and the latent heat was 81.98 J/g.
How is expanded perlite produced?
Expanded perlite is produced by heating the perlite to 760–1100 °C, at which point its indigenous water is converted to vapor and the material is caused to expand to 4–20 times its original volume, then the high-porosity and lightweight aggregates are formed [ 11 ].
Can expanded perlite be used as insulation filler?
Expanded perlite is used as insulation filler [ 13, 14 ], but few has been improved by filling the internal porous to change its water absorption. Thermal conductivity of water is 0.58 W/m K when the temperature is 4 °C.
