Smooth Polyurethane Foam Core FRP Door Sheet

Smooth polyurethane foam core FRP (glass fiber reinforced plastic) door panel is a new high-performance building material, which plays an increasingly important role in modern architecture. This material not only has excellent physical properties and durability, but also has a beautiful appearance that conforms to the design philosophy of modern architecture. This paper will introduce the manufacturing process, performance characteristics and application fields of smooth polyurethane foam core FRP door panels in detail.
2、 Manufacturing process
The manufacturing process of smooth polyurethane foam core FRP door panel mainly includes the following steps:
Raw materials: mainly including polyurethane foam, glass fiber, resin and other raw materials.
Production of master mold: According to the design requirements, the surface of the master mold should be smooth and flawless.
Laying glass fiber: Lay the glass fiber on the mother mold to ensure uniform distribution of the glass fiber.
Injection of polyurethane foam: inject polyurethane foam into glass fiber to form foam core.
Cure: Cure the foam core and glass fiber under certain temperature and pressure.
Demolding: Remove the cured door panel from the mother mold.
Trimming: Trim the edges of the door panel to ensure smooth and neat edges.
Painting: Paint the surface of the door panel to improve aesthetics and weather resistance.
3、 Performance characteristics
Smooth polyurethane foam core FRP door panel has the following performance characteristics:
High strength: because it uses glass fiber and polyurethane foam as the main materials, it has high strength and stiffness, and can withstand greater pressure and tension.
Durability: This material has excellent durability, can be used for a long time in various environments, and is not prone to aging or deformation.
Fire resistance: polyurethane foam has good fire resistance and can effectively prevent flame spread.
Thermal insulation performance: because polyurethane foam has good thermal insulation performance, smooth polyurethane foam core FRP door panel also has good thermal insulation effect.
Sound insulation performance: This material has good sound insulation performance and can effectively reduce noise.
Aesthetics: The smooth surface and various colors available for selection make this door panel highly aesthetically pleasing and suitable for various styles of architecture.
4、 Application field
Smooth polyurethane foam core FRP door panels are widely used in the following fields:
Building doors and windows: FRP door panels have high strength, durability, and fire resistance, making them an ideal choice for building doors and windows. Its aesthetics also make it the preferred choice for various styles of architecture.
Cold storage: The insulation performance of FRP door panels makes it an ideal choice for cold storage, effectively maintaining the temperature inside the warehouse and reducing energy consumption.
Sound insulation facilities: The sound insulation performance of FRP door panels enables them to be used for sound insulation facilities, such as soundproof walls, soundproof ceilings, etc., effectively reducing noise.
Public facilities: Public facilities need to withstand the test of high pedestrian flow, and the high strength and durability of FRP door panels meet this demand. The use of FRP materials for door panels in public places such as shopping malls, stations, airports, etc. can greatly improve durability and safety.
Transportation: FRP materials are lightweight, high-strength, wear-resistant, and corrosion-resistant, making them widely used in the field of transportation. FRP materials can be used to make subway doors, bus shelters, etc.
Landscape decoration: FRP materials can be made into various shapes and colors according to design requirements, making them very suitable for landscape decoration. Decorative facilities in places such as parks, squares, and streets can all be made of FRP materials.
Industrial applications: Due to its excellent corrosion resistance, FRP materials can be applied in industrial fields such as chemical engineering and environmental protection. FRP materials can be used for production of acid and alkali storage tanks, environmental protection equipment, etc.
