Refractorry Raw Materials in stock Acid-resistant brick features:
1. It has excellent chemical stability, strong acid resistance, and also has a certain degree of alkali resistance.
2. Precise size and smooth surface.
3. High hardness and resistance to rapid temperature changes.
Application
The products is widely used in petroleum, chemical engineering, metallurgy, electric power, chemical fiber, paper making, pharmacy, chemical fertilizer, food, dairy, fruit juice, electroplating and the tower room, pool, tank, and other anti-corrosion engineering and playing the anti-corrosive effect on under ground swage lines and open ground, etc.
Using instruction
1. General epoxy resin, acid-resistant clay, acid-resistant cement paving, construction according to the products use instruction of above manufacture
2. Using oxalic acid to clean concrete surface, so as to reach neutralization
3. The seam width of industrial acid 鈥搑esistant tile is about 8-1-mm, it is better that depth is equal to thickness to prevent disclosure
4. After paving, the surface should be scoured by groove acid to become more solid
