Description
High-temperature heat-insulating boards of calcium silicate for heat insulation with maximum operating temperature of 1000 to 1300 °C.
DESCRIPTION
Boards made of calcium silicate of 1000SC, 1100SC grades are ultra-lightweight products with excellent heat-insulating properties, high mechanical strength and good thermal stability. The board density ranges from 225 to 250 kg/m3. Boards 1000SC can be used at temperatures up to 1000 °C, boards 1100SC – at temperatures up to 1100 °C.
Surface treatment
Surfaces of boards 1000SC, 1100SC of standard dimensions can be treated with inorganic composition to give them water repellent properties. The products treated like this can be easily identified by their light blue color. Boards with water repellent surface treatment are additionally marked “WR” (this information should be taken into account when ordering and receiving the order).
DESCRIPTION
Boards of 1200CMS, 1300AS grades are lightweight, structural, heat-insulating products with a density of 800-950 kg/m3. They have especially high strength and application temperature of 1200 to 1300 oC.
All edges of products are full machined, so that the boards have smooth, hard and dust-free surfaces.
Due to exceptional thermal stability and low thermal conductivity of all types of board, these products provide the most effective heat insulation in the entire service temperature range.
Special mortar is used for the boards laying.
For recommendations for refractory and masonry mortars refer to the page «Refractory and masonry mortars».
With respect to fire safety, calcium-silicate-based boards comply with BS 476, part 4:1970 and DIN 4102, A1 are classified as non-flammable, flame-retardant and not emitting harmful gases.
APPLICATION
Boards are designed for heat insulation of all refractory structures (made of dense refractory bricks, heat-insulating bricks, refractory concretes, etc.) of various thermal units. The combination of high performance makes calcium-silicate-based boards an ideal choice for efficient heat insulation of baking, melting, heating and other furnaces, thermo cabinets, boilers, regenerators, pipelines and other high temperature installations and systems. Due to their resistance to carbon monoxide CO and hydrocarbons, they can be used in furnaces with reducing atmosphere. In particular, no changes were observed after the product samples holding in CO atmosphere for 200 hours at 450 °C.
