Working conditions of external wall perlite fire insulation board
Working conditions of external wall perlite fire insulation board:
1. The base wall and screed should be dry and qualified. The construction hole on the outer wall is blocked and the door and window frame is installed. The pipe clamps and other embedded parts required for plumbing and decoration work are left out of position or embedded, and the dark pipe and junction box of the electrical engineering are buried, and the threading of the dark pipeline is completed.
2. The ambient temperature of the outer wall perlite fire insulation board should be no less than 5 °C. Otherwise, it is not conducive to the construction of the bonding insulation layer and the plastering surface.
3. The working site of the outer wall perlite fire insulation board should be energized by water and keep the working environment clean.
4. During the construction of the wall body, the scaffolding for construction is preferably surrounded by a protective net. The phenolic insulation board not only helps the operator to be safe, but also avoids drying too fast after plastering. The minimum distance between the scaffolding tube or the tube head and the wall is 400mm for construction.
5, summer construction should be taken in the morning and evening, to avoid direct construction under the scorching sun, rainy days are not suitable for construction.
