1. After the aluminum silicate masonry is completed, the surface shall be cleaned once. The uneven areas must be smoothed with a pressing plate. Ceramic fiber board tiles must be cut and trimmed in large gaps to make the surface smooth and tight.
2. The thickness of ceramic fiber board tile lining must meet the requirements.
3. Thickness measurement: After measuring the length and width, mark nine measurement points according to their positions. Place the disc of the needle type thickness gauge gently on the sample, align the disc hole with the measurement point, and move the tip of the cursor Point it downward and carefully insert it into the disc hole. When the needle tip touches the sample, press the cursor lightly so that the needle tip passes through the sample and touches the glass plate to read the thickness.
4. The Al2O3 content of ceramic fiber board tiles is not less than 45%.
5. Before laying ceramic fiber board tiles, a test layout should be carried out. The separation layer should be firmly bonded and the gaps should be staggered.
