Effect of Surface Vitrification on the Properties of Insulation Board of Expanded Perlite

Abstract:

The surface-vitrified and expanded perlite is a new, high-quality insulation materials. It is studied to the effects on performances of the glass surface to expanded perlite insulation board, through comparing with the openings of expanded perlite, expanded and vitrified small ball and surface-vitrified and expanded perlite. A large number of experiments have been done on the physical properties of the insulation board with surface-vitrified and expanded perlite. It shows that the insulation board with surface-vitrified and expanded perlite has a low density, high strength, low water absorption, high obturator rate, low thermal conductivity, stable performance and so on. And the main reason is analyzed.
