Xinghui New Materials is a professional enterprise that produces anti-corrosion carbon bricks.
Anti corrosion carbon brick is a high-strength, acid resistant, and corrosion-resistant building material suitable for construction projects in corrosive environments such as chemical plants.
The ingredient for anti-corrosion carbon bricks is roasted granular smokeless coal as the aggregate, and its particle size depends on the size of the product: large bricks are 8-12 millimeters, and small bricks are 4-6 millimeters. The amount of anthracite added is about 60%. Coke should be added as fine powder, with a content of about 70% for particles smaller than 88 microns. The amount of binder added to blast furnace carbon bricks is usually 15-20%. In order to prevent oxidation, bricks are generally filled with coke powder or coal powder as protective fillers during firing. The firing temperature is between 1300-1450 ℃, the holding time is about 20 hours, and the total firing time is about 240-420 hours. When cooled to 40-60 ℃, it is discharged from the kiln. Carbon bricks are prone to catching fire and burning when fired at high temperatures.
The external dimensions are formed by compression molding, and the product has good molding quality and external dimensions. It can also produce special products according to user requirements, fully meeting the construction and masonry process requirements.
