Study on the Methods for Measuring Closed Cell Content of Cellular Glass and its Thermal Insulation Performance

Abstract:

The principle of measuring cellular glass by automatic densimeter was studied. The effect of pressure on closed cell content was researched in order to optimize the measuring pressure. The influence of closed cell content on the insulation property was analyzed by measuring thermal conductivity. The results showed that cell structure of cellular glass can distort or even be damaged with the increasing of pressure and the first condition for obtaining accurate closed cell content was to optimize the measuring condition and determine appropriate pressure. Closed cell content affects the insulation property of the cellular glass significantly.
