During the process of selecting ceramic fiber blanket, we must learn how to judge the quality of the blanket. This is very important for our future use. We must not only consider the price of the ceramic fiber blanket, but also consider the production technology and the quality of it.

Firstly, let’s look at the color of the blanket. The color of the good quality ceramic fiber blanket is white. The yellow color of the blanket is a poor quality product. Second, the good quality ceramic fiber blanket is produced by spinning process. The spun ceramic fiber blanket has long and thick ceramic fibers. Long fibers are tighter when they are interwoven with each other, so the blanket made from long fibers has good tear resistance and high tensile strength. However, the poor quality ceramic fiber blanket has short and thin fibers, so it is not strong and easy to tear. The poor quality blanket has poor resilience, easy to shrink and break when it is used in high temperature environment. Third, let’s look at the slag ball content inside the blanket. The good ceramic fibre blanket usually contains less slag balls. The poor quality blanket contains more slag balls. We can tear the blanket to see if it contains some brown or black residue.

It seems simple to judge the quality of the ceramic fibre blanket. In fact, there is a lot of knowledge when we judge it. Let’s start from the introduction of the judgment method. Step by step, we can understand more about it.
