Refractory calcium silicate board is mainly used in cement industry. The following will focus on what matters need to be paid attention to in the construction of refractory calcium silicate boards for cement kilns.
This issue we will continue to introduce masonry of refractory calcium silicate board:
6.When the refractory castable needs to be constructed on the refractory calcium silicate board, a layer of waterproofing agent should be sprayed on the refractory calcium silicate board in advance to prevent the refractory calcium silicate board from being damp and prevent the refractory castable from lack of water. For the refractory calcium silicate board used on the top of kiln, because it is difficult to spray the waterproofing agent upwards from the bottom, it is necessary to spray the waterproofing agent on the side in contact with the refractory castable before installation.
7. When building refractory bricks on the already-built refractory calcium silicate board, the brick seam must be staggered. If there is a gap, it must be filled with an adhesive.
8. For the upright cylinder or the straight surface, and the upright tapered surface, the lower end shall be the benchmark during construction, and the installation shall be carried out from bottom to top.
9. For each part, check thoroughly after the masonry is completed. If there is a gap or where the sticking is not strong, use the adhesive to fill it and stick it firmly.
10. For refractory calcium silicate board with great flexibility, no need to leave expansion joints. The lower part of the supporting brick board is plugged tightly with a refractory calcium silicate board and an adhesive.
Refractory calcium silicate board is widely used in equipment pipelines in the fields of electric power, metallurgy, petrochemical, construction, shipbuilding, etc. due to its own special characteristics, and has a good effect of heat preservation, heat insulation, fire protection and sound insulation.
