Effect of Composite Pore-Forming Agent on Performance of Light-Weight Thermal Insulation Materials

Abstract:

Production of porous and light-weight thermal insulation materials with reduced thermal conductivity and raised porosity were accomplished using sludge (SL) and sugar filter mud (SFM) as pore-forming agent respectively and composite pore-forming agent (CPFA) at different sintered temperature and holding time. The results of thermal insulation materials with flexural strength 7.65 MPa and thermal conductivity 0.056 W•m^-1•K^-1, obtained at 1000 °C for 0.5 h show that its the porosity factor raised to 40.60% and the bulk density of the materials decreased down to 1.265 g/cm³ using CPFA, closed porosity and dense structure in sample was observed by SEM
