What are the precautions for XPS extruded board construction1. XPS extruded board must ensure that the aging meets the 42-day requirement under natural environmental conditions. If the construction period is tight, backup measures should be taken for 5 days under 60-degree steam curing conditions. In order to avoid the insufficient aging period of the XPS board, it will continue to shrink after being placed on the wall, causing cracking, warping and deformation of the anti-cracking protective layer and decorative surface layer.
2. When pasting the XPS extruded board, the flatness should be adjusted by a rubber hammer, and it cannot be adjusted up and down or left and right, so as to avoid the overflow of the adhesive into the gap between the boards due to the wrong movement of the extruded board Inside, forming a cold bridge will cause a greater negative impact on the thermal insulation effect of the external thermal insulation system. A
3. During the construction of XPS extruded plastic board, in order to ensure the verticality of the positive corner, when constructing at the positive corner, the XPS board should be properly beyond the wall by a certain distance. After the XPS board is fully pasted, the unified elastic line After cutting, and smooth.
4. After the surface of the XPS extruded board is polished, the flatness should be controlled within 3mm/2m. The protective surface layer and decorative layer should not be used to make up for the unevenness of the insulation board, so as to avoid the localization of the anti-cracking protective layer mortar. Cracking potential.
5. It is not suitable for construction when the temperature is lower than 5℃ or higher than 38℃.
