Polyurethane Rock Wool Sandwich Panel Machine

The polyurethane rock wool sandwich panel machine is a specialized equipment used for producing building panels with multiple properties such as fire resistance, insulation, and sound insulation.

sandwich panel machine

The polyurethane rock wool sandwich panel machine manufactures high-performance building materials widely used in industrial plants, transportation hubs, cold storage and other places by compounding color coated steel plates, polyurethane foam materials and rock wool core materials.

The production equipment for polyurethane rock wool sandwich panels is mainly divided into two categories:

• Continuous pu rock wool sandwich panel production line
  By adopting an assembly line operation method, fully automated production from raw materials to finished products can be achieved
  Typical configuration includes: unwinding system → surface pretreatment → polyurethane foaming system → rock wool conveying → composite lamination → fixed length cutting → finished product stacking
  The length of the production line is usually between 45-100 meters, which can be adjusted according to product specifications

• Intermittent polyurethane rock wool sandwich panel production equipment
  Suitable for small batch customized production
  Adopting a segmented process, each process is relatively independent
  High flexibility, able to quickly switch product specifications

The core functional modules include:

• Foaming system: using two-component or multi-component cyclopentane foaming technology to precisely control the polyurethane foaming process
  

• Composite device: color steel plate, polyurethane and rock wool are firmly bonded by high pressure
  

• Cutting system: high-precision CNC cutting to ensure the dimensional accuracy of the sheet metal
  

• Control system: PLC centralized control, realizing digital management of parameters

Production process of polyurethane rock wool sandwich panels

• Material preparation stage
  Color steel plate: thickness 0.4-0.6mm, mostly made of aluminum zinc coated steel plate
  Rock wool core material: density 120kg/m ³
  Polyurethane raw materials: PU or PIR formula

• Composite production stage
  Mixing and spraying polyurethane raw materials through a precise metering system
  Foam forming between color steel plates and composite with rock wool
  Composite pressure controlled at 0.3-0.5MPa
  The production line speed can reach 3-25m/min

• Post processing stage
  Cut to length: error controlled within ± 1mm
  Edge processing: automatic edge banding or trimming
  Quality inspection: including thickness, flatness, fire resistance, etc

Performance and Advantage

• Automation control
  Adopting an integrated linkage control system, all control points are centralized in the main control center
  Equipped with fault self diagnosis and remote monitoring functions
  Parameter linkage adjustment to ensure process stability

• Energy saving design
  The energy consumption of the entire line is reduced by 40% compared to traditional equipment
  Adopting a fully enclosed internal insulation design, reducing heat loss by 30%
  High power and low-energy consumption motor configuration, capable of reaching process temperature within 1 hour after startup

• Modular structure
  Building block design, each module can be quickly replaced
  Strong interchangeability of components and easy maintenance
  CNC machining of key components with an accuracy of ± 0.1mm

• Environmental protection technology
  Using cyclopentane or 141B as foaming medium
  Exhaust gas collection and treatment system
  The waste recycling rate is over 95%

Polyurethane rock wool sandwich panels are widely used in:

• Industrial buildings
  Steel structure factory buildings and warehouses
  Power plants and substations
  Car showroom, 4S store

• Public Facilities
  Airport terminal, train station
  Sports venues, exhibition centers
  Hospitals, schools

• Special places
  Cold storage and cold chain logistics center
  Cleanroom, laboratory
  Soundproofing and noise reduction places

Maintenance and upkeep

• Regularly lubricate transmission components
  

• Foam system cleaned weekly
  

• Quarterly inspection of electrical system
  

• Annual comprehensive maintenance

Common fault handling

• Uneven thickness of the board: check the measuring system and conveying speed
  

• Composite instability: adjusting pressure and temperature parameters
  

• Cutting deviation: calibration of CNC system and guide rail
