Features of ceramic fiber blanket

1. High-temperature resistance: Ceramic fiber blankets can withstand high temperatures up to 1260°C, and will not embrittle or melt during long-term use. They have extremely strong fire resistance.
2. Lightweight and soft: Compared with traditional insulation materials, ceramic fiber blankets are lighter and softer, can be easily bent and folded, and are suitable for complex shapes and curved surface insulation.
3. Excellent thermal insulation performance: A ceramic fiber blanket has low thermal conductivity and a high thermal insulation effect, which can effectively reduce energy consumption and losses in industrial production.
4. Strong corrosion resistance: Because the ceramic fiber blanket is made of inorganic substances, it has good acid and alkali resistance and corrosion resistance, and can remain stable in harsh environments.
5. Environmentally friendly and healthy: Ceramic fiber blankets do not contain any harmful substances, will not produce any pollutants, and meet environmental protection requirements. At the same time, it does not release any toxic gases and is harmless to the human body during use.

How to choose the aluminum silicate blanket?

1. Choose the right thickness

The thickness of ceramic fiber blankets usually comes in various specifications such as 3mm, 5mm, 8mm, etc. Different thicknesses are suitable for different temperatures and occasions. Generally speaking, if the working temperature exceeds 1000℃, it is recommended to choose a ceramic fiber blanket with a thickness of 8mm; if the working temperature is below 800℃, you can choose a 3mm or 5mm thickness.

2. Pay attention to density and mass

The higher the density of the ceramic fiber blanket, the better the thermal insulation performance. Therefore, pay attention to the density index of the product when selecting. At the same time, we should also pay attention to the quality of the product. A high-quality ceramic fiber blanket has a uniform structure and soft feel.

3. Corrosion resistance

In the steel industry, corrosive substances such as acids and alkalis are often encountered, so the corrosion resistance of ceramic fiber blankets is also an important factor to consider. Generally speaking, the ceramic fiber blanket with better acid and alkali resistance will have a longer service life.
