The automatic continuous pu color steel rock wool sandwich panel production line mainly consists of the following key parts:

• Open coil system: Adopting a dual coil design, equipped with an automatic correction device to ensure the smooth unfolding of the color steel plate coil.
  

• Forming unit: It includes multiple precision rolling processes and adopts an optimized roller system to produce various types of color steel panels (such as corrugated panels, trapezoidal panels, etc.).
  

• Rock wool processing system: equipped with high-precision cutting device, using high-pressure air flow cleaning technology to ensure that the surface of rock wool is free of debris.
  

• Polyurethane foaming system: The core part adopts a high-pressure foaming machine with high proportioning accuracy and precise temperature control.
  

• Composite compression system: The multi-stage press adopts PID closed-loop control, and the pressure uniformity reaches over 95%.
  

• Fixed length cutting system: Integrated laser ranging and image recognition technology, cutting accuracy ± 1mm, oblique angle error<0.5 °.
  

• Automatic stacking system: using a six axis robot with vacuum suction cups, the stacking neatness reaches 98%, and the maximum load can reach 2 tons.

The production of high-quality polyurethane color steel rock wool sandwich panels requires key monitoring of the following parameters:

• Polyurethane foam quality: density deviation controlled within ± 3%, closed cell rate>90%, thermal conductivity ≤ 0.022W/(m · K)
  

• Adhesive strength: Peel strength between color steel plate and core material ≥ 0.15MPa, interface bonding strength between rock wool and polyurethane ≥ 0.10MPa
  

• Dimensional accuracy: Length deviation ± 2mm, width deviation ± 1mm, thickness deviation ± 0.5mm
  

• Weather resistance: After 1000 hours of accelerated aging test, the color difference Δ E is ≤ 3, and the coating has no cracking or peeling

With the advancement of technology, the application of polyurethane color steel rock wool sandwich panels has broken through the traditional construction field:

• Special industries: anti-static sheet materials are used in electronic factories, and corrosion-resistant sheet materials are used in the chemical industry
  

• Cold Chain Logistics: Application of Ultra Low Temperature Plate in Cold Storage Construction
  

• Clean engineering: Antibacterial board used in hospitals and laboratories
  

• Acoustic Engineering: Customized Sound Absorbing Structure for Studio Special Soundproofing Panels

As a representative of high-end equipment manufacturing, the polyurethane color steel rock wool sandwich panel production line has directly promoted the transformation and upgrading of the building materials industry with its technological progress.
