When choosing aluminum silicate ceramic fiber blanket we should learn how to judge the quality of aluminum silicate ceramic fiber blanket. This will have a great impact on the future use, so it is necessary to consider not only the price of the product, but more importantly, the production level of manufacturer and the quality of the products.
1. First of all, we should look at the color. Color of good aluminum silicate ceramic fiber blanket is white. If the color of blanket is yellow. The blanket is generally a low-grade product.
2. Good blanket is produced with spun fiber technology. Long fibers are relatively tight when intertwined, so tear-resistant and tensile strength is good. Bad ceramic fiber blankets are produced with short-fiber, they are easy to shred, and their resilience is poor, and easy to shrink and break in high temperature environments.
3. Shot content. Shot content of good aluminum silicate ceramic fiber blanket is below 15%. We can peel the fiber blanket to see if it contains some brown or black residue.
