Thermal shock resistance
Thermal shock resistance (i.e. rapid cooling and heat resistance) is a significant advantage of ceramic fiber board. It can repeatedly raise and lower the temperature, without cracks, and will not reduce the strength of the product. Calcium silicate board is composed of granular materials, which have much lower cold and heat resistance than ceramic fiber board. Therefore, a certain amount of fiber must be added to the calcium silicate board.
Digestion, swelling, and extrusion performance
Due to the toughness and strength characteristics of ceramic fiber board, when used as an insulation backing, timely absorption and digestion of the expansion force of refractory castable or refractory castable during the heating process can avoid cracking of bricks or castable due to stress. The product strength and service effect are intact, and calcium silicate board.
Reuse performance
Ceramic fiber board is highly reusable, especially in the maintenance of kiln walls. Be careful not to damage the ceramic fiber board. Due to the significant decrease in strength of calcium silicate board after combustion and its brittleness, it is generally not reusable.
Transportation, Storage, and Construction
(1) Ceramic fiber board has the characteristics of high strength, high toughness, collision resistance, falling resistance, and non fragility, providing greater convenience for transportation (especially loading and unloading vehicles), storage, and construction. Calcium silicate board is a brittle material that is prone to fracture or missing corners and edges, which not only causes product loss but also affects the effectiveness of use. Therefore, attention must be paid to avoiding collisions during transportation, storage, and construction.
(2) Ceramic fiber board has excellent waterproof performance A simple test is that the product does not sink in water for 24 hours, which brings great convenience to transportation, storage, and construction, especially in rainy and humid environments. In addition, due to the waterproof performance of ceramic fiber board, waterproof agents cannot be used for waterproofing treatment during construction. Calcium silicate board is a type of board that has strong water absorption during application and construction, and must undergo adsorption and waterproofing treatment.
(3) In architecture, ceramic fiber boards are easier to cut than calcium silicate boards and have less environmental pollution (dust).
