High strength alkali resistant castable needs to be mixed with water into mortar vibration casting, or the production of various types of precast blocks, spraying type can be semi-dry spraying construction. It is widely used in cement kiln preheater lining, pipe lining, cooling machine lining, coal spray gun dressing, front and back kiln, cooling machine and other high-temperature parts. Can be prefabricated into various specifications of the precast blocks, or spraying construction (preheater lining).
Because the flue gas velocity of circulating fluidized bed boiler is high, the erosion of coal ash particles and the erosion of flue gas are serious, the use environment of the lining wear resistant refractory is bad, the operation practice has proved that the traditional refractory has not adapted to the operation needs of circulating fluidized bed boiler. The series of alkali resistant castable material has high density, high strength wear resistance; Higher thermal strength; Excellent resistance to erosion; Good volume stability and erosion resistance at high temperature.
Our production of alkali resistant castable is the use of high silicon and low aluminum good alkali resistant ceramic particles as aggregate and powder, with aluminate cement and admixture prepared alkali resistant castable. When alkali erosion occurs in the process of use, high silicon and low aluminum components react with alkali gas to form high viscosity liquid phase, which is attached to the surface of castable to form enamel-like protective layer, thus preventing alkali erosion and eliminating "alkali crack" phenomenon.
Alkali resistant castables must be kept in dry warehouses. The effective storage period is 12 months for barrels and 4 months for bags. During loading and transportation, there must be protective measures against rain, snow and humidity.
