The polyurethane rock wool sandwich panel line is usually composed of a series of interrelated equipment, including raw material preparation equipment, mixed foaming equipment, composite pressing equipment, quality testing equipment, cutting and packaging equipment, etc. These devices work together to complete the entire process from raw material input to finished product output.

Production Process Flow

• Raw material preparation: Mix polyurethane raw materials (polyols and isocyanates) in proportion and store them at a constant temperature in a designated environment to prevent crystallization or viscosity changes. At the same time, prepare the rock wool core material to ensure that its fiber length and density meet the requirements.
  

• Mixed foaming: Inject polyurethane raw materials into the mixed foaming machine, and achieve rapid mixing and foaming of the raw materials through high pressure and precise control. This step is crucial for the production line and directly affects the insulation performance of the sandwich panel.
  

• Composite pressing: The foamed polyurethane is combined with rock wool core material and covered with galvanized steel plate or color steel plate on the upper and lower surfaces synchronously. Pressing is carried out through the press machine on the continuous production line to tightly bond the materials of each layer.
  

• Quality inspection: Conduct quality inspections on the produced sandwich panels, including peel strength testing, combustion performance testing, and dimensional stability testing, to ensure that the product quality meets relevant standards.
  

• Cutting and packaging: cut and package qualified sandwich panels according to customer requirements for transportation and installation.

Characteristic

• Highly automated: The continuous polyurethane rock wool sandwich panel line adopts advanced automation control system, which can achieve the full process automation production from raw material input to finished product output, greatly improving production efficiency.
  

• High flexibility: The continuous production line of polyurethane rock wool sandwich panels can be flexibly configured according to customer needs to produce sandwich panels of different specifications and properties. Meanwhile, the equipment on the production line can also be modularized for easy maintenance and upgrading.
  

• Energy saving and environmental protection: The automatic production line of polyurethane rock wool sandwich panel fully considers the requirements of energy saving and environmental protection in its design, adopts advanced energy-saving technologies and equipment, and reduces energy consumption and waste emissions.
  

• Stable quality: Through strict quality control and testing methods, we ensure that the produced sandwich panels have stable and reliable quality, meeting customer needs.

With the continuous development of the construction industry and the increasing demand for insulation materials, the market demand for polyurethane rock wool sandwich panels, as a high-performance insulation material, will continue to grow. Therefore, the production line of polyurethane rock wool sandwich panels will also usher in broader development prospects.

The polyurethane rock wool sandwich panel line is an efficient, flexible, energy-saving and environmentally friendly combination of production equipment, which can meet the demand of the construction industry for high-performance insulation materials. In the future, with the continuous advancement of technology and the expansion of the market, the production line will be further improved and optimized to provide higher quality products and services for the construction industry.
