Misunderstanding 1: Bulk density (bulk density) the larger the better
The main chemical components of ceramic fiber are AI2O3 and SIO2, which are made by silk technology. Ceramic fiber blankets, ceramic fiber modules, and ceramic fiber folded blocks adopt the method of fiber interweaving to form a void unit structure. Within a reasonable bulk density of 200kg/m3-220kg/m3, the bulk density increases, the thermal conductivity gradually decreases, and its heat dissipation loss will gradually decrease. However, if the bulk density is excessively increased to 240 kg/m3, the cell structure performance of the pores will also decrease, the thermal conductivity will increase instead, and the heat loss will increase. Therefore, one-sided pursuit of too high bulk density is not advisable.
Misunderstanding 2: The tighter the fiber folded block, the better
The installation of the ceramic fiber module is an integral structure formed by rows of mutually squeezed folding blocks, compensation blankets between rows, and backing flat blankets. The installation of ceramic fiber lining pays attention to the overall effect. Only when the overall sealing effect is good, can the ceramic fiber kiln roof not run out of wind and leak fire.
Excessive extrusion will cause the surface of the ceramic fiber kiln ceiling to be uneven, and the end surface cannot be flattened. This will cause the compensation blanket installed at the end to be squeezed not firmly, and there will be a through seam at the junction of the row and the row, which is likely to cause fire leakage and affect the kiln roof. The overall sealing effect and the service life of the kiln roof.
