Polyurethane Sandwich Panel Production Line: Waterproof Products

Advantages of Polyurethane Sandwich Panel Production Line with Edge-Sealed Rock Wool

The characteristics of the polyurethane sandwich panel production line with edge-sealed rock wool include the adoption of a double-drive wheel extrusion process. The product completes the entire board production process from slurry, main material, cloth laying, compounding, and secondary pressing in one go. The wall panel equipment has a high degree of automation, runs smoothly, and allows for arbitrary adjustment of specifications. The polyurethane sandwich panel production line equipment is a new type of large wall panel that is green, environmentally friendly, energy-saving, and has excellent insulation and fireproof properties. This equipment can be paired with both domestic and international frame structures, steel structures, and special-shaped column structure systems.

The production process of the insulation board equipment is simple, with a high degree of automation, low labor intensity, assembly line operations, no noise, and no emission of three wastes. The polyurethane sandwich panel production line with edge-sealed rock wool has low energy consumption, does not require high temperatures or high pressure, and utilizes the heat released by its own chemical reactions to meet production process requirements. The products produced by this equipment have flat, smooth surfaces and high density, truly realizing the industrialized assembly line production of new building partition panels. This greatly reduces the labor intensity of production workers.

How Does the Exterior Wall Insulation Board Produced by Polyurethane Sandwich Panel Production Line Achieve Waterproofing?

• When encountering window and door openings, the length and width of the board should be judged on-site according to the position of the wall to determine the length and width of the exterior wall insulation board.

  
  

• Waterproofing and moisture-proofing: Each board is individually wrapped in a plastic bag. Check the plastic bag for damage before installation. If damaged, add an additional good plastic bag.

  
  

• Before applying the sealant to the top of the completed construction before hanging the stone, cover it with a plastic cloth to prevent rainwater from leaking into the glass wool board. For exposed areas of the glass wool board at the corners, use aluminum foil strips of the same material as the surface layer to stick them firmly. Apply silicone sealant at stone joints.

  
  

• Avoid thermal bridges. Embed iron pieces in the beams of each structural layer and weld them to the main keel. The embedded parts form a thermal bridge. Apply 15mm thick silicate cement mortar to the inside of each side beam to isolate the thermal bridge.

  
  

• After laying the non-combustible glass wool, check the anchoring points, flatness, and bonding quality between the glass wool boards. Only proceed with the dry-hang stone work after passing the inspection.

  
  

• Strictly control the thickness and width of the glass wool board to be uniform and straight, ensuring a consistent fit. At corner areas, overlap the interlocking joints.

  
  

• The exterior wall insulation boards produced by by the equipment of polyurethane sandwich panel production line should not be exposed for long periods. To prevent moisture, each board is individually wrapped in a plastic bag. Cover the top of the wall with a plastic cloth over the glass wool board. After installation, promptly inspect it and install the dry-hang stone on the outside, and promptly apply weather-resistant silicone sealant to prevent water infiltration during rain.

  
  

• During installation, the board seams should be tightly pressed, adjacent boards should be flush, the seam gaps should not exceed 2mm, and the height difference between boards should not exceed 1.5mm.

  
  

• The exterior wall insulation board construction using the polyurethane insulation board production line equipment should not be conducted when the ambient temperature is below 5℃, or during strong winds above level-5 and rainy weather.
