Polyurethane core technology in the sandwich panel industry
As an important material in the modern construction industry, polyurethane sandwich panels have been widely used in industrial plants, cold storage, clean workshops and other construction fields due to their excellent thermal insulation performance, lightweight characteristics and structural strength. In the production process of polyurethane sandwich panels, the choice of catalyst directly affects the quality, production efficiency and final performance of the product.
Manufacturing process and catalyst function of polyurethane sandwich panels
The production of polyurethane sandwich panels is to inject liquid polyurethane raw materials between two layers of metal plates (or other surface materials) and quickly foam and solidify them under the action of catalysts. In this process, catalysts play three key roles:
1. Reaction rate control: precisely control the balance between foaming and gelling reactions
2. Cell structure optimization: ensure the formation of a uniform and fine closed-cell structure
3. Enhanced bonding performance: improve the bonding strength between the foam core and the panel
