Acid Resistant Bricks
Product Description
Acid-resistant bricks are primarily made from quartz, feldspar, and clay, produced through high-temperature oxidation and decomposition. Their primary component is silicon dioxide, exceeding 70%. High-temperature firing produces a large amount of mullite, a highly acid-resistant material.
Feature:
Acid Resistance: With an acid resistance of 95% to 98%, they offer excellent corrosion resistance to most acids (except hydrofluoric and hot phosphoric acids), such as hydrochloric, sulfuric,
and nitric acids, as well as alkalis of varying concentrations at room temperature. However, they are not resistant to high-temperature molten alkalis.
Low Water Absorption: With a compact structure and a water absorption rate generally between 0.5% and 5.0%, they are not easily penetrated by solutions, maintaining excellent corrosion resistance and facilitating use in humid environments.
High Strength and Bearing Capacity: High-temperature firing results in high hardness and strength, excellent wear resistance, and the ability to withstand the pressure and friction of heavy objects. They are not easily damaged by external forces such as friction and impact.
Easy to Clean and Maintain: The smooth surface resists dirt accumulation, making cleaning easy without the use of chemicals. Installation is also simple, allowing for direct installation on substrates such as concrete and ceramic tiles, shortening the construction cycle.
Other Properties: It also offers excellent thermal insulation and electrical insulation properties. It is resistant to oxidation and contamination at room temperature, effectively preventing electrochemical and galvanic corrosion.
Frequently produced sizes:
230*113*15/20/30mm; 230*113*40/50/60mm; 150*75*15/20/30mm; 150*150*15/20/30mm; 200*200*15/20/30mm; 300*300*15/20/30mm
All sizes brick can be made single side groove or double sides groove, glaze or non-glaze.
Special size and OEM service are provided, too.
Non Glaze: anti-skidding, anti-exposure.
Glaze: Easy to clean, smooth and clear.

Application
Acid-resistant bricks are mainly used in anti-corrosion projects in the chemical, metallurgical, electroplating, pharmaceutical, food and other industries. They can be laid on the ground, walls, tanks and other areas that come into contact with acidic media to resist acid corrosion and protect the substrate.
