Xinghui New Materials factory is a professional enterprise that produces anti-corrosion carbon bricks. Anticorrosive carbon bricks are a high-strength, acid resistant, and corrosion-resistant building material, and are an ideal lining material for equipment such as chemical phosphoric acid reaction tanks and phosphoric acid storage tanks.
The production process of carbon brick is roughly similar to other Fire brick, but carbon must be prevented from oxidation at high temperature, so raw materials and products must be baked in a reducing atmosphere. Anthracite shall be roasted before use to eliminate volatile matter, sulfur and moisture, and improve the volume stability, mechanical strength and oxidation resistance of Anthracite. Coke needs to be dried first to avoid difficulties in forming due to high moisture content and cracking of the product during the firing process. Asphalt should be melted and dehydrated first, so that its moisture content is less than 0.2%, and the dehydration temperature should be between 120 and 160 ℃.
