Fiberwall® Bonded 30 Modules are designed for hot-face veneering over existing refractory linings at temperatures up to 1538 °C. The felt used in Bonded 30 Modules is made from a 50-50 blend of Fiberfrax® high-purity bulk fibres and Fibermax®, a polycrystalline mullite fibre patented by Unifrax. The use of Fibermax in the felt formulation produces a product that demonstrates extremely low shrinkage at elevated temperatures.
Bonded modules are typically mortared into place over existing refractory using 0.908 kg to 1.36 kg of Fiberstick™ refractory cement per module. This lining over refractory (or veneering) approach not only increases the efficiency of the refractory lining but helps to protect it from further degradation.
