HEAT-INSULATING MODULAR BLOCKS
Heat-insulating modular blocks are made of a mullite-siliceous refractory fiber, produced by melting of pure aluminum and silicon oxides in electric furnace with fiber formation by the blowing method. A thermostable inorganic binding agent is added to fibers to impart strength and elasticity to the material.
Zirconium or chrome oxides are introduced into fiber composition to increase the batting application temperature.
The products are formed by strips of the material that are compressed as blocks with preset dimensions. Compaction allows the material shrinkage compensation, reduction of material thermal conductivity at high temperature and increase of the material application temperature. Modular blocks are intended for installation on metallic fastenings or bonded with inorganic glues.
