Processing industry and heat treatment industry:
1) Clean up floating ash, oil and other debris remaining on the concrete wall and empty drum parts.
2) Remove the cracked concrete blocks, inclusions, empty drums, etc., and repair them again.
3) It is required that the surface roughness deviation of the pasted ceramic fiber board should not exceed 4mm, and the protruding concrete surface should be polished and the concave part should be repaired (1:2.5 cement mortar should be plastered when the thickness is more than 6mm, and polymer bonded mortar should be repaired when the thickness is less than 6mm); To ensure that the flatness of the entire wall is within 4mm, and the Yin and Yang angles are square and smooth.
4) The mortar used in construction is divided into special bonding mortar and special adhesive for high temperature surface layer.
5) The weight ratio of the mixed bonded mortar is water: mortar =1:5, stir while adding water; Stirring time is not less than 5min, stirring must be full, uniform, moderate consistency, and a certain viscosity.
6) After the mortar is prepared, it must be left for 5 minutes, the aluminum silicate board is different from the ceramic fiber board, and it should be stirred again before use, and the mixed mortar should be used up within 1 hour.
7) In order to enhance the bonding force between the extruded board and the bonding mortar, before pasting the ceramic fiber board.
