Composite Polyurethane Sandwich Panel Production Line

The composite polyurethane sandwich panel production line is a high-end equipment that integrates mechanical automation, chemical foaming technology, and material composite process. It is mainly used to produce building insulation panels with polyurethane as the core material and color steel plates or aluminum foil as the surface layer.

Core equipment

• Double track laminating machine: By shaping the polyurethane foam layer at high temperature and high pressure, the density and flatness of the board are ensured to be uniform.
  

• High pressure foaming system: using a PLC controlled mixing head to achieve precise mixing of black and white materials, with a foaming closed cell rate of over 90% and low thermal conductivity.
  

• Automated cutting unit: equipped with infrared length measurement and circular saw, with a cutting accuracy of ± 1mm, supporting fixed length production (standard board length 4-12m, width 1-1.2m).

Product performance advantages

• Fire safety: After adding flame retardants, it can meet the B1 level fire protection standard, extinguish automatically in case of fire, and have no melting droplets.
  

• Energy saving and environmental protection: Compared with traditional EPS boards, the insulation performance is improved by 50%, and the building energy consumption is reduced by 30%.
  

• Structural integration: With a compressive strength of ≥ 0.3MPa, it can be directly used as a building enclosure structure, reducing construction processes.

Application scenarios

• Industrial buildings: factory roofs/walls.
  

• Cold chain logistics: In the construction of -30 ℃ cold storage, polyurethane edge sealing technology effectively prevents cold bridge effect.
  

• Green building: In conjunction with photovoltaic roof systems, achieve low-carbon production construction operation throughout the entire cycle.

The specific equipment selection needs to be matched according to parameters such as product thickness and production capacity. It is recommended to prioritize the consideration of models with double track lengths ≥ 24m to ensure stability.
