It is strictly prohibited to stack in the open air. The curtain wall rock wool board should be stacked and protected from moisture.
5. Construction should have the following conditions:
5.1. The treatment of the stratified layer of the base wall and its cement mortar and the installation of the embedded parts are completed.
5.2. The necessary construction equipment and labor protection supplies should be prepared.
5.3. Construction-specific scaffolding should be erected and qualified for safety inspection. The distance between the scaffolding pole and the horizontal pole and the wall and the corner of the wall should meet the construction requirements.
5.4. The base wall shall be solid and flat, the surface shall be dry, and there shall be no cracking, hollowing, loosening or pan-alkali. The bonding strength, flatness and verticality of the cement mortar leveling layer shall be in accordance with (Quality Acceptance Specification for Building Decoration Engineering) GB50210 The requirements for the quality of ordinary plastering works.

Precautions
1. Pay attention to rain, not rainy.
2. For the cold preservation, it is necessary to add a moisture-proof layer. Under the condition of extremely low temperature, the resin should be insulated with rock wool without resin. The moisture-proof layer must also be fireproof.
3. When the temperature exceeds a certain temperature, for example: 200 °C, the insulation must be added with appropriate external protection, so that the thickness and bulk density of the rock wool board will not be changed.
4. For the large-diameter and flat-wall equipment used for rock wool finished products insulation, when surpassing 200 °C, be sure to remember the rock wool board manufacturer's å®å˜±: add insulation nails, (around 400mm spacing) external protection should be close.
5. Equipment, insulation nails and pipes to be insulated are suitable for corrosion protection and can receive appropriate coatings. In addition, there should be no leaks. This can achieve better results.
6. If the rock wool board finished product is subject to mechanical wear in the case of outdoor thermal insulation, it should be made of metal or plastic. Then pay attention to the joint location, seal the joint, add the glue seal when needed, and the stack of the wrapping layer is not less than 100mm.
7. When the object to be insulated is placed at 90 degrees and has a certain height, the insulation layer of the rock wool board must have a positioning pin or a support ring, and the spacing must not exceed 3 meters to prevent the insulation material from sliding down when there is vibration. .
8. In order to achieve the heat loss of the small goal of the Zui, the joints of the rock wool board and the felt must be butt jointed. If there are multiple layers of insulation, the cross joints need to be intertwined to avoid forming a thermal bridge, which must be cold when cold. bridge.
