The durability of refractory China fire brick simply refers to its service life and how long the service cycle is, which is related to its quality and performance. So what are the factors that affect its durability in production and use?
The durability of refractory China fire brick refers to the ease with which the bricks will interact with the surrounding environment and various natural factors during use. The durability affects the performance of the object itself. It mainly includes physical, chemical and biological effects.
1. Physical effect: generally refers to dry and wet changes, temperature changes, freeze-thaw cycles, etc. These effects will cause the volume change of the refractory China fire brick material or cause the expansion of internal cracks, and the material will gradually deteriorate.
2. Chemical action: It includes the erosion of aqueous solutions of acids, alkalis, salts and other substances and harmful gases. These erosions will gradually deteriorate the material and then destroy it.
3. Biological action: refers to the invading action of fungi and insects, including the destruction of materials due to moth-eaten and decay. Therefore, the durability of the material is actually a measure of the material’s ability to maintain its original properties for a long time under the above-mentioned various effects to ensure safe and normal use. In actual engineering, refractory China fire bricks are often affected by a variety of damage factors at the same time. The quality of the material is different, and the content of its durability is different.
4. Refractory China fire brick is often combined with some or comprehensive factors such as chemical action, dissolution, freeze-thaw, wind erosion, temperature difference, humidity difference, friction, etc. Its durability indicators include more frost resistance, weather resistance, resistance Permeability, wear resistance and other requirements, the durability of the same material is not static.
The above are the factors that affect the durability of refractory China fire brick. When producing refractory China fire brick, we should pay attention to the correct storage and selection of its raw materials, and pay attention to its use environment during use, which can greatly reduce changes in durability and prolong the use of bricks. life.
