High temperature furnace insulation boards are designed to withstand high temperatures and provide excellent insulation for furnaces and other high-temperature applications. These boards are made up of various materials that can withstand high temperatures without breaking down or melting.
Some of the most commonly used materials in high temperature furnace insulation board include alumina, silica, mullite, and zirconia. These materials are all ceramic-based and offer excellent thermal insulation properties, making them ideal for use in a wide range of high-temperature applications. Ceramic fiber board is versatile used in high temperature furnaces, with following advantages：
- The lower volume density is one tenth of that of lightweight refractory bricks;
- Low thermal conductivity and low heat capacity;
- Excellent thermal shock resistance performance
- Good chemical stability
- Resistance to sudden cold and heat
- No need for oven
- Fast heating and cooling speed
- Energy saving and consumption reduction, which is one eighth of that of refractory bricks
- Simple construction and convenient maintenance, lower construction and labor charge
- Long service time
Alumina is a high-purity ceramic that is commonly used in high temperature furnace insulation boards. It is known for its excellent thermal shock resistance and high chemical resistance, making it suitable for use in harsh and corrosive environments. It also has a high density, which makes it ideal for use in applications where strength and durability are important.
Zhuqing Ceramic fiber board AL content:
1260 Ceramic fiber board >42%
1260 HA board >52%
Polycrystalline fiber >72%
suitable for 1000deg. C to 1600deg. C kiln/furnaces.
Silica, on the other hand, is a highly versatile ceramic that is used in a wide range of applications. It is known for its excellent thermal insulation properties, which make it ideal for use in high-temperature furnace insulation boards. It also has high chemical resistance, making it suitable for use in corrosive environments.
Zhuqing Soluble fiber board Si content 60-68%, calcium and magnesium and silica as main components, and it has the property of being smoothly discharged even if it is absorbed into the human body.
Mullite is another ceramic material that is commonly used in high-temperature furnace insulation boards. It is known for its excellent thermal stability and its ability to perform well in high-temperature applications. It also has a low coefficient of thermal expansion, which makes it ideal for applications where dimensional stability is important.
Zhuqing Polycrystalline fiber is mullite base, which has Al content >72% and service temperature 1500-1700deg, C.
Finally, zirconia is a ceramic material that is known for its excellent thermal insulation properties and its ability to withstand high temperatures. It is also highly resistant to chemical attack and has a high strength-to-weight ratio, making it ideal for use in high-temperature furnace insulation boards.
In conclusion, high temperature furnace insulation boards are made up of a variety of ceramic materials that can withstand high temperatures and provide excellent thermal insulation properties. Alumina, silica, mullite, and zirconia are all commonly used in these boards, and each material offers unique properties that make it suitable for use in different applications.
