Technological innovation of phenolic foam core material production line:

• Modular intelligent production line: using CNC machining of core components, with a running speed of 30m/min and energy consumption only 40% of traditional equipment, supporting PU/PF/PIR multi material switching production.
  

• Environmentally friendly foaming process: Cyclopentane foaming technology replaces traditional fluorocarbons, reduces greenhouse gas emissions, and achieves adjustable core density through formula optimization.
  

• Composite surface layer adaptability: It is compatible with various surface materials such as color steel, aluminum foil, glass magnesium board, etc., meeting the differentiated needs of purification workshops, cold storage and other scenarios.

Core production process flow

• Raw material pretreatment
  Phenolic resin and curing agent are mixed in proportion, and foaming agent and surfactant are added to form a uniform slurry.
  Temperature control accuracy ± 1 ℃ to ensure foam stability.

• Continuous lamination molding
  The double crawler type laminating machine realizes synchronous combination of upper and lower color steel plates and liquid phenolic foam, and the plate thickness error is ≤ 0.5mm through microwave heating and curing.

• Post processing and cutting
  The automatic trimming and slitting system supports customized sizes (common specifications: 1200mm × 600mm, thickness 50-150mm).
  Fireproof coating spraying (optional) can increase the fire resistance limit to more than 2 hours.
