Unshaped refractories refer to refractory materials without fixed shape and size, usually in the form of powder, slurry or coating. They have some characteristics, such as plasticity, easy construction and repair, strong adaptability and so on. The following are some applications of Unshaped refractories:
1. Repair and maintenance: Unshaped refractories are often used for repair and maintenance of high-temperature equipment such as furnaces, kilns, and heat treatment equipment. Due to the high plasticity and cohesiveness of the monolithic refractory, it can fill and plug cracks, worn parts or damaged areas in the furnace.
2. Thermal insulation layer: Unshaped refractory materials can be used to construct thermal insulation layer to reduce heat conduction and loss. By coating or spraying monolithic refractories on the surface to form a thermal insulation layer, it can provide thermal insulation, reduce energy consumption, and improve the thermal efficiency of equipment.
3. Coatings and Coatings: Unshaped refractory materials can also be used as coatings or coatings to increase the refractory properties of the material. These coatings can be applied to metal surfaces, masonry, insulation boards, etc. to provide fire protection against fire spread and heat transfer.
4. Bonding and cementing materials: Unshaped refractory materials are often used as bonding and cementing materials to fix components such as refractory bricks, ceramic fibers, and refractory fiber felts. They can be mixed with water or specific cements to form a slurry or paste and are used to build complex shapes or join different parts of refractory structures.
5. Fireproof Filling: Unshaped refractory materials can be used to fill voids, ducts or other spaces in building structures to provide fire insulation and protection. These fills can expand in the event of a fire and create a fire-resistant barrier, slowing the spread of fire and the spread of smoke.
In general, monolithic refractories are widely used in various high temperature environments. They provide flexibility and adaptability to meet the fire resistance needs of different equipment and structures and are used for repair, insulation, fire protection and connection.
