Product Information
Heat insulation board is rigid product made from ceramic fiber which are vacuuming formed with organic and inorganic binders, with or without mineral fillers. These are manufactured over a wide range of grades densities and hardness.
The board is featured with high temperature stability, low thermal conductivity, even density, and excellent resistance against thermal shock and chemical attack. They can be used as individual component attack. They can be used as individual component of furnace lining or as hard hot face layer as backup insulation.
Features of heat insulation board
1. Low heat storage and low thermal conductivity;
2. High compression strength;
3. Non–fragile materials and good toughness;
4. Accurate dimension and good palneness;
5. Structure homogeneity and easy machining;
6. Easy to install
7. Continual production, even fiber with stable property;
8. Excellent heat stability and thermal shock resistance
Typical application of heat insulation board
1. Cement building industry, kiln back lining-thermal insulation;
2. Ceramic industry-lining of various kilns for thermal insulation;
3. Petrochemical and metallurgy industries- back linings, wall linings, and linings-thremal insulation;
4. Glass kiln lining and back lining thermal insulation;
5. Heat treatment furnace kiln back lining thermal insulation;
6. Aluminium factories-reduction cell firebricks back linings;
7. High temperature reaction, heating device-wall lining and back linings
