Light Acid Resistant Castable
Light acid and acid resistant castables have castables that are resistant to acids, heat, heat, shock, and heat. Resistant refractory castable is suitable for flue lining or chimney (flue) lining operated in wet dust removal (desulfurization) mode.
The flue gas emitted from the coal-fired power plant is saturated with water after wet deacidification, and the flue gas temperature drops to between 50℃ and 70 ℃. The same fashion contains a small amount of corrosive medium such as sulfuric acid and entrained chloride. Due to the high permeability, the low concentration of sulfuric acid and chloride is more corrosive and destructive to the inner wall of concrete than the high concentration sulfuric acid solution. Therefore, the anticorrosion performance of the chimney lining after the wet desulfurization of flue gas from coal-fired power plants is higher. Requirements. The special acid proof and heat insulating refractory castable for the power plant chimney produced by Rongsheng Factory can be directly poured into the inner layer of the chimney, which has the advantages of heat preservation, heat insulation, acid resistance and corrosion resistance, and has the advantages of high compressive strength, and replaces it. The original traditional lightweight bricks and lightweight acid-resistant bricks are easy to construct.
Light Acid Resistant Castable Manufacturing Process
Light acid resistant refractory castable is characterized by expanded shale pellets (diameter 5-10 mm, weight 400-475 kg, diameter 1-5 mm, weight 100-150 kg), fly ash (180-300 kg), floating beads (20-30 kg), bonding. The composition of the agent and the curing agent, the binder can be sodium silicate or potassium silicate solution (module M2.4-M3.0, 300-350kg), the curing agent can be made of ammonium phosphate or ammonium chloride (30-55kg). The method is to weigh the components according to the above ratio, wherein the expanded shale pellets have a bulk density of 400-550 kg/m3, the refractory material is once expanded and can not be used for crushing, and then the components after weighing are At normal temperature (above 5 °C), the castables with a dry bulk density of 800-1100 kg are obtained by mechanical or manual agitation.
Light Acid Resistant Castable Price
The price of acid-resistant castables and light acid-resistant refractory castables are related to raw materials, content and specific gravity. The density of ordinary products is generally 1.6-2.0, of course, the price is also cheap; the weight of heavy products is 2.0 or more. The higher the weight of refractory products, the higher the price. The more expensive, the more common light acid-resistant refractory castables have the following proportions: 0.6, 0.8, 1.0, 1.2, etc. The lighter the acid-resistant castables, the higher of the light acid resistant price.
