The mineral composition of Resist Acid Fireproof Clay Brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6%~7% impurities (oxides of potassium, sodium, calcium, titanium and iron).

 

The firing process of Resist Acid Fireproof Clay Brick is mainly the process of continuous dehydration and decomposition of kaolin to form mullite (3Al2O3·2SiO2) crystals.

 

The SiO2 and Al2O3 in the Resist Acid Fireproof Clay Brick form eutectic low-melting silicate with impurities during the firing process, which surrounds the mullite crystals.


Resist Acid Fireproof Clay Brick are weakly acidic refractory products, which can resist the erosion of acidic slag and acidic gas, and have a slightly weaker resistance to alkaline substances. Clay bricks have good thermal properties and are resistant to rapid cold and rapid heat

 

Competitive Advantage:

  1. Competitive Price. Make your products competitive in the market.

  2. Abundant Experience. Meet clients’ quality requirement.  

  3. Different Moulds. Save mould fees for you.

  4. Strict Quality Control. Make the products with high quality.

  5. Large stocks. Guarantee prompt delivery.
  6. Professional Packing. Avoid damage and secure the goods in transportation

 

Features

1. as high acid resistance
2. Low water absorption
3. Oxidation at room temperature is not easy
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

 

 

The Resist Acid Fireproof Clay Brick is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks.

 

In addition to the high refractory mullite crystals, the clay bricks also contain nearly half of the low melting point amorphous glass phase.


In the temperature range of 0~1000℃, the volume of Resist Acid Fireproof Clay Brick expands uniformly as the temperature rises.

 

The linear expansion curve is approximately a straight line, and the linear expansion rate is 0.6%~0.7%, which is only about half of that of silica bricks.

 

When the temperature reaches 1200 ℃ and then continue to rise, its volume will start to shrink from the maximum expansion.

 

The residual shrinkage of Resist Acid Fireproof Clay Brick leads to the loosening of mortar joints in masonry, which is a major disadvantage of clay bricks.

 

When the temperature exceeds 1200°C, the low melting point substances in the Resist Acid Fireproof Clay Brick gradually melt, and the particles are tightly pressed against each other due to surface tension, resulting in volume shrinkage.


Production practice in China has proved that before crushing, high-aluminum clinker is strictly sorted and classified, and stored in tiers.

The use of bauxite clinker and combined clay fin grinding method can improve product quality.
