Perlite insulation board construction technology

Construction preparation and precautions:

1.Before construction, it is necessary to check whether the quality of the insulation board material is reliable, and see if the material is broken and missing.

2.Before laying, it is necessary to find the position of the flat layer and the air insulation layer, and then carry out the construction of the flat layer and the vapor insulation layer.

3.During construction, it is necessary to ensure that the materials are dry and the laying is placed flatly.

4.During construction, attention should be paid to protecting the board surface, and do not transport or trample on the board surface.

Construction process: 1Clean the layer and prepare some fine slag or expanded perlite bulk material as a liner for the plank, about 3-5mm thick with the padding.

2.When laying the board, the seams of the board should be staggered, and it should be filled with hydrophobic perlite bulk material and 107 glue mixed into a slurry.

3.After the board surface is paved, a layer of 107 glue mixed cement slurry is painted as a binding layer, then the cement mortar is smeared and then the leveling layer is leveled, and finally, the waterproof layer is made on the leveling layer, and the cement mortar is continued to be repeatedly applied.

4.Find the position of the flat layer and the vapor insulation layer, and pay attention to keeping the base layer flat, clean and dry after the construction of the flat layer and the vapor insulation layer is completed.

5.Check whether the plate-shaped insulation material is broken or missing, and it should be sawed flat and repaired when laying.

6.After laying the dry board, it is worth noting that the dry laying plate-like insulation material should be close to the surface of the base layer, paved and stable, and the upper and lower joints should be staggered with each other when laying in layers, and the joints should be filled with similar material debris.

7.Paste plate-shaped insulation materials, make ash cakes with thermal insulation slurry made of hydrophobic perlite, punch ribs, and plaster all over again, pay attention to the uniform and natural application, and there can be no convex.

8.Press the anti-crack mortar into the alkali-resistant mesh, brush the elastic primer, and brush off the excess material with water-resistant water-resistant putty to make the surface smooth and dry.

9.Paint well according to the engineering design requirements.
