The specific quality standards of ceramic fiber blankets that are widely used in various industries are probably few people will know. Let’s spread this small problem to everyone.
1. First of all, according to the classification temperature, the working temperature of each type of ceramic fiber blanket is different.
The working temperature of the standard ceramic fiber blanket is about 1050 °C, the working temperature of the high-purity ceramic fiber blanket is 1100 °C, the working temperature of the high-aluminum ceramic fiber blanket is about 1200 °C, and the best temperature-resistant zirconium-containing type The ceramic fiber blanket can be used at temperatures up to 1350 °C.
The working temperature of the ceramic fiber blanket is high among all the heat insulating materials, and can be applied to various occasions to meet the temperature requirements of people.
2. The color of the ceramic fiber blanket is slightly different depending on the type thereof, and the higher the temperature resistance, the whiter the color of the ceramic fiber blanket.
Ceramic fiber blankets generally have a bulk density of 64/96/128/160, but usually more people use 96 and 128, which are the density of all types of ceramic fiber blankets, and ceramic fibers. The type of blanket has nothing to do with it.
3. Permanent shrinkage of the ceramic fiber blanket (insulation for 24 hours, bulk density of 128kg/m3), the permanent line shrinkage of each type of ceramic fiber blanket averages around -3 or -4.
4. The slag ball content of each type of ceramic fiber blanket should be less than 15, in order to make the ceramic fiber blanket flat from the outside. I will give you this today, and the rest will be added in the next article.
