Preparation of New Alumina Silicate Refractory Fiberboard and Study on its Performance

Abstract

The preparation of alumina silicate refractory fiberboard by wet vacuum filter molding process, alumina silicate fibre is the matrix material, and high-temperature resistance adhesive is the agglutinant. Experiments made in conditions of no liquid glue, and not adding fiber, influence of cycling time on liquid glue concentration, density of fiberboard, and retention of cementing compound was studied; effect of density of fiberboard on thermal conductivity is also discussed. The results showed that the optimum liquid glue concentration is 9.41%, cycling time is 28h (replenish liquid glue after 28h). Density of alumina silicate fiberboard is 289kg/m3, and alumina silicate fiberboard can resistance to 1200 °C.

Research on Preparation of New Aluminum Silicate Fiber Adiabatic Paper

“…Aluminium silicate fibers are prepared by melting at a high temperature of 1500℃-2000℃ [1], then spray the magma out in high-temperature and high speed, thus different lengths of aluminium silicate fibers are produced. Nowadays, aluminium silicate fibers are recognized as the most research valuable new adiabatic material at home and abroad [2].…”
