In what range is the suitable temperature for polyurethane spray insulation construction, and the appropriate temperature is required for polyurethane spray insulation construction on the exterior wall base surface. Let's learn about it together!
It is more cost-effective to apply polyurethane spray insulation at a suitable temperature. The bubble method sprayed when the ambient temperature is 15℃ is more than 25% smaller than the foam sprayed when the ambient temperature is 25C. Choosing a suitable temperature for polyurethane spray insulation construction will reduce the spraying cost. After all, the chemical reaction temperature of the product in the equipment is the same, and the environmental temperature that affects its reaction speed is the key, so spraying construction should better control the change of environmental temperature.
The suitable temperature for polyurethane spray insulation construction is 10℃-40℃. After all, the lower the temperature, the reaction speed of the on-site spray foam will be reduced, the shrinkage rate of foam molding will increase, and the size of foam spray will be smaller. The higher the temperature, the larger the spray foam, which effectively saves raw materials.
The above is an introduction to the suitable temperature for polyurethane spraying and heat preservation. For more information on polyurethane, please continue to pay attention to Hightop Machinery.
