Q:What precautions should be taken during the construction process?
A:1.Tear off the film after construction to prevent rainwater from immersing into the corroded board surface.
2.After the construction is completed, the iron filings and sundries on the board should be removed in time to avoid rust on the board after rain.
3.Avoid other hard objects from scratching the surface coating.
4.During the handling process, the force on the board surface should be uniform, and the supporting points should be uniform. Note that it is strictly forbidden: when taking the upper and lower boards, it is strictly forbidden to directly drag and transport the board and the board (to prevent the burr at the cutting place from scratching the surface and affecting the effect of the product on the wall)
5. When the site needs to be cut, the cutting place must be cleaned up.
Q:How to store polyurethane insulation sandwich panel?
A:Polyurethane has good corrosion resistance, and the only thing that destroys it is ultraviolet rays, so pay attention to prevent sun exposure and avoid storage in the open air. Such as long-term storage, should be stacked stacked.
Q:What is the working temperature of polyurethane insulation panel?
A:The temperature range of polyurethane insulation board is between -30°C and +90°C, and the short-term use temperature can reach +250°C without any damage.
Q:Can polyurethane insulation board resist thermal deformation?
A:Any material undergoes a dimensional change under the action of temperature. When the density of non-veneer rigid polyurethane foam is 30~60Kg/m3, the thermal expansion coefficient is 5~8·10-5·K-1. When the temperature rises, for example, from 10°C to 30°C (temperature difference = 20K). Rigid polyurethane foam insulation boards over one meter can expand 1~1.6mm, which is normal.
Q:Can I get samples for inspection?
A:We will provide free samples to you before order confirmation.
