Difference Between Clay Bricks and Refractory Bricks

As we all know, bricks have been used for centuries as a building material due to their durability, wytrzymałość, and aesthetic appeal.
Jednakże, not all bricks are created equal. There are various types of bricks available in the market, and each one has its own unique properties and characteristics that make it suitable for specific applications.
W tym artykule, PER Refractory will discuss the difference between clay bricks and refractory bricks, two commonly used types of bricks.

1. Wstęp

Bricks are an essential building material and have been used for construction purposes for thousands of years.
They are made by molding clay or other materials into the desired shape and then firing them in a kiln.
Clay bricks and refractory bricks are two types of bricks that are commonly used in construction and other applications.
While they may look similar, they have significant differences in terms of their composition, manufacturing process, properties, and applications.

2. What are Clay Bricks?

2.1 Composition
Clay bricks are made from natural clay and shale that is formed into a rectangular shape and then fired in a kiln at high temperatures. The clay is usually mixed with water and other additives such as sand, Limonka, or ash to improve its strength and durability.

2.2 Manufacturing process
The manufacturing process of clay bricks involves the following steps:

2.2.1. Preparation of raw materials – The clay and shale are crushed and mixed with water and other additives.
2.2.2. Molding – The mixture is molded into the desired shape using a molding machine or by hand.
2.2.3. Drying – The bricks are then dried in the sun or in a kiln for several days.
2.2.4. Firing – The bricks are fired in a kiln at high temperatures ranging from 800°C to 1200°C.

2.3 Nieruchomości
Clay bricks have the following properties:

2.3.1. High compressive strength
2.3.2. Good insulation properties
2.3.3. Niska przewodność cieplna
2.3.4. Good sound absorption properties
2.3.5. Low water absorption

3. What are Refractory Bricks?

3.1 Composition
Refractory bricks are made from high-quality refractory materials such as alumina, krzemionka, magnezja, i cyrkonia. These materials have high melting points and can withstand high temperatures without breaking down or deforming.

3.2 Manufacturing process
The manufacturing process of refractory bricks involves the following steps:

3.2.1. Preparation of raw materials – The refractory materials are crushed and mixed with water and other additives.
3.2.2. Molding – The mixture is molded into the desired shape using a molding machine or by hand.
3.2.3. Drying – The bricks are then dried in the sun or in a kiln for several days.
3.2.4. Firing – The firebricks are fired in a kiln at high temperatures ranging from 1400°C to 1800°C.

3.3 Nieruchomości
Refractory bricks have the following properties:

3.3.1. High refractories
3.3.2. High resistance to heat and thermal shock
3.3.3. High mechanical strength
3.3.4. High chemical resistance
3.3.5. Low porosity

4. Differences between Clay Bricks and Refractory Bricks

4.1 Composition
The main difference between clay bricks and refractory bricks lies in their composition.
Clay bricks are made from natural clay and shale, while refractory bricks are made from high-quality refractory materials such as alumina, krzemionka, magnezja, i cyrkonia.
This makes refractory bricks much more resistant to high temperatures and thermal shock than clay bricks.

4.2 Aplikacje
Clay firebricks are commonly used in construction for building walls, floors, i inne konstrukcje.
They are also used in the manufacturing of fireplaces, kominy, and other heat-resistant structures.
Cegły ogniotrwałe, on the other hand, are used in high-temperature applications such as kilns, piece, i spalarnie.
They are also used in the manufacturing of glass, steel, and other materials that require high temperatures.

4.3 Strength and Durability
Refractory bricks are much stronger and more durable than clay bricks.
They can withstand much higher temperatures without breaking down or deforming, making them ideal for high-temperature applications.
Gliniane cegły, on the other hand, are not as strong or durable and are more prone to cracking and crumbling under high temperatures.

4.4 Resistance to Heat and Chemicals
Refractory bricks have a high resistance to heat and chemicals, making them ideal for use in harsh environments.
They are able to withstand high temperatures without deforming or breaking down, and they are also resistant to the corrosive effects of chemicals.
Gliniane cegły, on the other hand, are not as resistant to heat and chemicals and may break down or crumble over time.

5. How to Choose between Clay Bricks and Refractory Bricks

The choice between clay bricks and refractory bricks depends on the application.
If you are building a fireplace or chimney, clay bricks may be a suitable choice.
If you are building a kiln or furnace, refractory bricks would be a better choice due to their high-temperature resistance.
