Polyurethane Glass Wool Sandwich Panel Production Line

The polyurethane glass wool sandwich panel production line is an intelligent production system that integrates chemical synthesis, fiber processing, and building materials manufacturing. It adopts a "sandwich" structure composite process, which combines polyurethane rigid foam with glass wool through continuous production to form high-performance building panels.

The annual production capacity of the polyurethane glass wool sandwich panel production line can reach 500000 to 1.5 million square meters, and the entire line length is usually 80-120 meters, achieving fully automated operations from raw material input to finished product packaging.

Production Process

• Raw material pretreatment system
  Polyurethane section: equipped with precise polyol/isocyanate metering system, using high-pressure foaming machine to achieve raw material mixing
  Glass wool section: Basalt raw materials are melted at 1600 ℃ and then spun into 3-5 μ m ultrafine fibers through centrifugal spinning

• Continuous composite production line
  Double track laminating machine: temperature zone control, pressure adjustable range 0.1-0.5MPa
  Intelligent foaming system: using infrared scanning to monitor the foaming height in real time, combined with an adaptive feeding robot arm
  Fiber paving machinery: adjustable angle for cross laying mesh, achieving three-dimensional structural enhancement

• Post processing section
  Online edge trimming system: high-speed cutting of diamond cutting tools
  Automatic palletizing robot: maximum gripping weight of 200kg, positioning accuracy of ± 0.5mm
  Microwave curing device: 2.45GHz frequency, curing efficiency increased by 40%

The polyurethane glass wool sandwich panel production line can flexibly adjust production specifications through modular design, with a standard panel width range of 1000-1200mm and a thickness of 30-200mm, meeting different building enclosure requirements.
