The thickness of the production and processing ceramic fiber blanket lining must meet the requirements;
Thickness measurement After measuring the length and width, mark the nine measuring points according to the position shown in the figure. Place the disc of the needle gauge directly on the specimen so that the disc hole is aligned with the measuring point and the cursor With the needle tip facing down, carefully insert it into the hole of the disc. When the tip of the needle touches the specimen, gently press the cursor to make the tip of the needle touch the glass plate and read the thickness.
The ceramic fiber has an Al2O3 content of not less than 45%;
Before the ceramic fiber is laid, the test should be carried out, and the bonding layer should be firmly bonded and the gaps staggered;
After the ceramic fiber is built, the surface finishing is carried out. If the unevenness is uneven, it must be flattened with a pressure plate. The ceramic fiber bricks must be trimmed at a large gap to make the surface smooth and tight;
Each time the protective layer is applied, it must be carried out in two rounds to ensure that the thickness and thickness of the protective layer are uniform.
