Last issue we mainly introduced installation methods and processes of high temp fiber board in decoration and industrial furnace building. This issue we will continue to introduce installation methods and processes of high temp fiber board in processing industry and heat treatment industry.
三．Processing industry and heat treatment industry.
1. Clean up residual ash, oil and other debris and hollow parts on the concrete wall.
2. Remove the cracked concrete blocks, inclusions, hollow drums, etc. from the top plate and repair them again.
3. It is required that the surface flatness deviation of the high temp fiber board is not more than 4mm.. If the deviation is more than 4mm, the surface of the protruding concrete should be polished and the hollow part should be repaired.（If the hollow part is more than 6mm, use 1:2.5 cement mortar to repair. If the hollow part is less than 6mm, use polymer bonded mortar to repair ）In order to ensure that the flatness of the entire wall is within 4mm, the yin and yang angles are square and smooth.
4. The mortar used in the construction is divided into special bonding mortar and high temperature special adhesive for the surface layer.
5. The weight ratio of the mixed mortar is water: mortar = 1:5, stir the mortar while adding water; the stirring time is not less than 5 min, the stirring must be sufficient and uniform, the consistency is moderate, and there is a certain viscosity.
6. After the mortar is prepared, it must be allowed to stand for 5 minutes. Stir again before use. The prepared mortar should be used up within 1 hour.
Above is installation methods and processes of high temp fiber board in processing industry and heat treatment industry Hope this can bring help to furnace builders.
