Fireproof PU Sandwich Panel Line

The fireproof pu sandwich panel production line is a combination of equipment specifically designed for producing polyurethane sandwich panels with excellent fireproof performance. This production line usually integrates multiple advanced technologies and processes to ensure that the produced sandwich panels have excellent fire resistance, insulation, sound insulation, and other properties.

The Fireproof PU Sandwich Panel Line mainly consists of an unwinding system, a steel plate feeding system, a steel plate automatic docking system, a reinforcement unit, a forming machine system, a high-strength bonding system between steel plates and polyurethane, a corona system, steel plate preheating, a double track machine and heating system, cutting saws, film covering equipment, cooling equipment, an automatic palletizing machine, and a packaging system. In addition, it may also include specific equipment such as automatic rock wool slitting and conveying systems (for rock wool sandwich panel production), n-pentane foaming systems (for polyurethane foaming), etc.

During the production process, the uncoiling system sends the steel plate into the production line. After undergoing processes such as steel plate feeding, automatic docking, reinforcement pressing, and forming, it is bonded, foamed, and cured with polyurethane foam material in a double track machine and heating system. The cured sandwich panel undergoes subsequent processing such as cutting, laminating, and cooling, and is finally packaged and stacked by an automatic palletizer.

Product Features

• Excellent fire resistance: The fireproof polyurethane sandwich panel is made of flame-retardant materials, which are not easy to burn at high temperatures, and can form a carbon layer on the surface during combustion, effectively blocking the spread of fire.
  

• Good insulation effect: Polyurethane materials have the characteristics of high closed cell rate and low thermal conductivity, so fireproof polyurethane sandwich panels have excellent insulation performance.
  

• Lightweight and High Strength: The sandwich panel is made of lightweight materials, but has high strength and rigidity, making it easy to handle and install.
  

• Good sound insulation performance: Polyurethane material has good sound insulation performance and can effectively reduce noise transmission.

Fireproof polyurethane sandwich panels are widely used in fields such as construction, cold chain, and transportation. In the field of architecture, it can be used for thermal insulation and fire prevention of walls, roofs, partitions and other parts; In the field of cold chain, it can be used for insulation and heat preservation in places such as cold storage and refrigerated trucks; In the field of transportation, it can be used for fire prevention and insulation in projects such as subways and tunnels.

With the continuous improvement of people's requirements for building safety and energy efficiency, the market demand for fire-resistant polyurethane sandwich panels continues to grow. Meanwhile, with the continuous advancement of technology and the reduction of costs, the production efficiency and product quality of fire-resistant polyurethane sandwich panels are also constantly improving. Therefore, the production line of fireproof polyurethane sandwich panels has broad development prospects.

The Fireproof PU Sandwich Panel Line is an efficient and advanced production equipment that can produce sandwich panels with excellent fire resistance, insulation, sound insulation and other properties, widely used in construction, cold chain, transportation and other fields.
