Acid proof brick are special ceramic bricks, use quartz, feldspar and clay as main raw material and sintered under high temperature furnace firing, which can resist high temperature, shock chilling and strong acid corrosion. They are widely used in reaction tanks, towers, troughs and stirring ponds in metallurgical and chemical processes.
acidproof brick Characteristics and advantages:
1.Has high acid resistance
2.Low water absorption
3.oxidation at room temperature is not easy
4.Not easy to be contaminated by the media and other
5.High pressure resistance
6.Easy to clean
7.Strong acid and alkali corrosion resistance(parameter>99.8)
8.Convenient for installation
9.Uniform gas and liquid distribution
10.Reliable structure and chemical stability
11.Long service life, more than 3 years warranty
12.High Working temperature: 1650-1720C
13.Accurate size, small Tolerance
acidproof brick Application:
Acid proof brick is widely used in the industries of petroleum, chemical, pharmaceutical, food dairy,juice,papermaking, chemical fertilizer, pesticide, chemical fiber, textile, metallurgy, power plants, electroplating room, which was used as the anti-corrosion lining of tower, tank and groove and also play its corrosion resistance in sewage treatment engineering and exposed ground work site.
