These days, they use all kinds of brick facades for design. In the market, you will come across names such as white brick. Each of the facade bricks has a different design, color and feature that are suggested for different contexts. Therefore, the price of the facade brick is expressed according to the construction conditions and its features. Refractory brick is another facade model that has different properties due to the specific materials and raw materials and the way they are combined.
2. Insulation
This brick is the best heat insulation model that can withstand high temperatures well. This type of brick can be used to cover fireplaces and furnaces and can withstand temperatures up to 3,200 degrees Fahrenheit. Its light weight models allow thinner furnace walls to be designed and improve work efficiency. . It is also effective in reducing the implementation cost. Another hot topic of this brick in terms of insulation is sound insulation. Fireproof models are not soundproof compared to bricks and are usually not sold with this title.
2- Temperature resistance
This brick is also known as fireplace brick due to its fire resistance. He uses it to design cooking rooms with ovens, making fireplaces and fire boxes. Unlike normal bricks, heavy models have little porosity. For this reason, ordinary bricks are easily decomposed at high temperatures of about 1200 degrees Fahrenheit. Also, one of the best choices for making a brick barbecue is firebrick, which requires the least amount of heat resistance due to its high resistance to temperature. has the change.
Concert
This brick has a density of 2.4 compared to water, and light models are designed with a relative density of 0.60. Its dense models are the best choice for fireplaces and fire boxes of gas stoves, which face less wear when burning materials. Light models are also more suitable for insulating places that are abused. It can be used without being mechanically placed.
2- Color and shape
This brick is naturally white in color. Its desired color is produced as a slurry that changes the color of the brick during the production process. Some colors such as red, black, moss green, espresso, etc. are very popular, and this allows everyone to buy according to their taste. They don't have the variety of colors of refractory bricks and they are not produced uniformly. Because there is unevenness on their surface.
2- thermal conductivity
Ordinary bricks have higher thermal conductivity than refractory bricks. While fireproof models tolerate high temperatures easily. This feature is created due to the use of primary materials such as ceramics, iron oxide and other additives that absorb high temperature.
So dense bricks are the best choice for places with high mechanical and thermal pressure and with insulating properties. More is provided. The higher the density, the greater the brick's resistance to damage.
Composition
The composition of Samal refractory brick is 23% alumina and 73% silica, iron oxide, titanium and other metal oxides are observed in their manufacturing process. The main ingredients of normal brick also include silica, magnesium, lime, iron oxide, alkalis and alumina. Less or more of each item has a great impact on the structure of the brick. Of course, the way to combine the above-mentioned items is much simpler for ordinary bricks, which are refractory bricks, while refractory bricks have a high density and are produced with a more coherent structure.
