Fire Clay Anti-acid Refractory Brick for Chimney of Chemical and Electric Power Industry
Acid-resistant bricks are corrosion-resistant materials made of quartz, feldspar, and clay as the main raw materials. They are made of high-temperature oxidation and decomposition. They have high acid and alkali resistance, low water absorption, and are not easily oxidized at room temperature and are not easily polluted by media. In addition to acid and hot phosphoric acid, it has excellent anti-corrosion effects on warm chlorine brine, hydrochloric acid, sulfuric acid, nitric acid and other acids and alkalis of any concentration at room temperature. It is widely used in petroleum, chemical industry, metallurgy, electric power, chemical fiber, papermaking, pharmacy, fertilizer, food, dairy industry, fruit juice, electroplating room, tower, pool, tank, tank and other anti-corrosion projects, and in underground sewage channels and open ground etc. Both can exert its corrosion resistance.

The main component of acid-resistant bricks is silica, which forms a large amount of mullite under high temperature calcination. This is a substance with high acid resistance. Because of the compact structure of the acid-resistant bricks, the water absorption rate is small, so it is at room temperature It can also withstand any concentration of alkaline medium, but it is not resistant to high-temperature molten alkali. Acid-resistant bricks contain more than 70% silica and are sintered. They are mostly used in acid ditch, acid well, and acid storage in the chemical industry. Depots and impacted ground with large acid load.
Product characteristics of acid-resistant bricks
1.Acid-resistant bricks have high acid resistance, good temperature
and acid resistance, low water absorption, not easy to oxidize at
room temperature, and not easy to be contaminated by media.
2. In addition to hydrofluoric acid and hot phosphoric acid, it has excellent corrosion resistance to wet chlorine, salt water, hydrochloric acid, sulfuric acid, nitric acid and other acids and alkalis of any concentration at room temperature.
Product application of acid-resistant bricks
The acid-resistant bricks produced by our company are widely used
in petroleum, chemical, pharmaceutical, food, paper, fertilizer,
pesticide, chemical fiber, textile, smelting, power plants and
other industries, as well as the anticorrosive lining of towers,
pools, tanks, and tanks, and are used in sewage treatment
Engineering and working places such as open ground play its role in
acid and corrosion resistance. Acid-resistant bricks can withstand
most media except hydrofluoric acid, hot phosphorus, and
concentrated alkali, and have excellent corrosion resistance to wet
chlorine brine, hydrochloric acid, sulfuric acid, nitric acid and
other acids and alkalis at any concentration at room temperature.
effect
Under the condition of little temperature fluctuation, it is used
to prevent acid gas or liquid from corroding flake or block
acid-resistant ceramics.
According to the water absorption rate, it can be divided into
three categories.
The water absorption rate of category 1 is not more than 0.5%, the
water absorption rate of category 2 is not greater than 2.0%, and
the water absorption rate of category 3 is not greater than 4.0%;
According to the working surface, it is divided into two types:
glazed and unglazed, usually with a back pattern of 1mm or more.
The main physical performance requirements: the bending strength of
the first type acid-resistant brick is not less than 39.2MPa, the
acid resistance is not less than 99.8%, and the rapid cold and hot
at 100℃ will not crack; the second type of acid-resistant brick is
not less than 29.4MPa, Acid resistance is not less than 99.8%,
100°C rapid cooling and rapid heating will not crack once; Category
3 acid-resistant bricks have a bending strength not less than
19.6MPa, acid resistance not less than 99.7%, and 100°C rapid
cooling and rapid heating will not crack once.
It is mainly used for the lining of reaction tower tanks,
anti-corrosion vessels, trenches and other facilities whose
temperature is lower than 100℃, acid-resistant floors and wall
skirts, etc. It should not be too high when used on a vertical
surface to prevent it from falling off.
