The Polyurethane Edge Sealing Rock Wool Panel Line usually consists of multiple parts, including raw material preparation area, molding area, edge sealing area, curing area, and finished product cutting and packaging area. Each region is coordinated and coordinated through advanced automation control systems to ensure the continuity and efficiency of the production process.

Production process flow

• Raw material preparation: Prepare high-quality rock wool core materials, color coated steel plates, and polyurethane raw materials. Rock wool core material needs to undergo pre-treatment processes such as cutting and combing to ensure uniform fiber distribution and certain strength.
  

• Forming: The color coated steel plate is precisely bent by a CNC roller press to form the desired appearance shape, laying the foundation for seamless fitting between the rock wool core material and the steel surface in the future. The rock wool core material is evenly laid between two layers of color coated steel plates.
  

• Edge sealing: The fully automatic glue injection machine injects two-component polyurethane along both sides of the board, foams and expands to fill the gaps, and solidifies to form. This dense polyurethane edge sealing not only improves the overall strength of the board, but also enhances its insulation, fire resistance, and moisture resistance.
  

• Curing: After edge sealing, the board enters the curing zone and undergoes curing treatment in a constant temperature and pressure environment to ensure a strong bond between the polyurethane edge sealing and the color coated steel plate and rock wool core material.
  

• Cutting and packaging: The cured board is cut into the required size by a cutting machine and packaged for transportation and storage.

Product Features

• Excellent insulation performance: Rock wool core material has a three-dimensional mesh structure, which can lock in air and achieve efficient insulation. Meanwhile, polyurethane edge sealing also has certain insulation properties, making the insulation effect of the entire board more significant.
  

• High fire rating: The rock wool core material is an A-level non combustible material with a fire resistance limit of over 1000 ℃, meeting international fire standards. Polyurethane edge sealing also has certain flame retardant properties, further improving the fire safety of the board.
  

• Good moisture resistance: Polyurethane edge sealing can effectively block moisture from entering the interior of the board, avoiding the strength and performance degradation of rock wool core materials caused by water absorption.
  

• Beautiful appearance: The color coated steel plate is precisely formed by a CNC roller press, making the appearance of the plate flat, beautiful, and has a certain degree of decorative value.

Polyurethane edge sealed rock wool board is widely used in industrial plants, public buildings, and special environments such as cold storage and clean workshops due to its excellent insulation, fire resistance, and moisture resistance properties. In industrial plants, it can be used for the exterior walls and roofs of steel structure plants; In public buildings, it can be used as the enclosure structure for large-span buildings such as airport terminals and train stations; In special environments, it can be used for thermal insulation in cold storage and wall decoration in clean workshops.
