The product structure of EPS sandwich panels usually consists of the following parts:
Surface material: The surface material of EPS sandwich panel can be color-coated steel plate (such as galvanized plate, stainless steel plate, anti-static color-coated steel plate). These surface materials usually have good corrosion resistance and decorative effect.
Core material: The core material of the sandwich panel is polystyrene foam (EPS), which is a self-extinguishing material with excellent thermal insulation, cushioning, shock resistance and aging resistance. EPS material is widely used in the manufacture of sandwich panels due to its light weight and high performance.
Adhesive: The surface material and core material are compounded by heat-curing adhesive under heating and pressure in a continuous molding machine to form an ultra-light building panel.
Special treatments: Some EPS sandwich panels may undergo additional treatments, such as fire retardant treatments, to improve their combustion performance.
Structural form: EPS sandwich panels can have different structural forms, for example, they can be flat plates or structures with periodic truss cores. The latter is a very important ultra-lightweight structure.
Mechanical properties: There have been a series of studies on the mechanical properties of EPS sandwich panels, such as bending capacity, wind load resistance and impact resistance.
Application technology: The application technology of EPS sandwich panels includes its use in construction, such as roofs, walls, etc., and how to improve its durability and load-bearing capacity.
This structure makes the EPS sandwich panel lightweight, high-strength, good in thermal and sound insulation properties, and high in construction efficiency, so it has been widely used in the construction industry.
