The polyurethane color steel sandwich panel machine is an integrated industrial equipment, which is used to continuously produce sandwich panels composed of color steel plate (outer layer) and polyurethane foam (core layer). It is widely used in building insulation, cold storage construction, industrial plants and other fields, and has the characteristics of efficient production, environmental protection and energy conservation.
Glue coating system
Using high-precision spraying technology, uniform coating is achieved through components such as adhesive storage tanks and sponge application pads to ensure the bonding strength between the color steel plate and the core material.
Some equipment is equipped with visual observation windows to monitor the quality of adhesive coating in real time.
Foaming and laminating device
High pressure foaming machine: the polyurethane black and white materials are mixed and then injected into the color steel plate interlayer to form a hard foam through chemical reaction, which is evenly filled and has a high porosity.
Laminated conveyor: Modular design, equipped with servo lifting mechanism, can flexibly adjust the thickness of the sheet without the need for hydraulic system, reducing the risk of leakage.
Cutting and collection unit
Integrated automatic cutting machine and buffer storage rack, hydraulic damping system reduces the rate of sheet damage.
Some equipment is equipped with industrial dust removal systems to centrally process cutting dust and improve the working environment.
Energy saving and efficient
Adopting high-power and low-energy design, the overall energy consumption of the line is only 40% -50% of similar products.
The internal insulation design can quickly raise the temperature above 5 ℃ at room temperature without the need for an additional insulation workshop.
Intelligent control
The PLC centralized control system realizes digital adjustment of parameters such as temperature, pressure, and speed, and supports remote monitoring and fault self diagnosis.
Modular modular assembly with strong component interchangeability and easy maintenance.
Environmental Protection and Safety
Polyurethane core material is flame retardant, and some equipment supports switching between fire-resistant core materials such as rock wool and glass wool.
No cold bridge design, avoiding heat loss while reducing noise pollution.
Construction field
Roof/wall panels: lightweight and high-strength, with a large span, suitable for large-span structures such as sports arenas and airports.
Cold storage panel: specially designed for low-temperature environments, with a thickness of up to 200mm, and a concave convex groove structure to enhance air tightness.
Industrial sector
Purification workshop: The surface of the antibacterial constant purification board is easy to clean, meeting the dust-free requirements of the pharmaceutical and electronic industries.
Activity room: quick installation, detachable and reusable, suitable for temporary housing or battlefield hospitals.
Product scalability
Through mold replacement, the same production line can produce sandwich panels with various core materials such as polyurethane (PU/PIR), rock wool, glass wool, etc.
Automation upgrade
Introducing robot palletizing and fully automatic cotton feeding system to reduce manual intervention and improve production stability.
Application of Green Materials
Developing fluorine free polyurethane foaming technology to reduce carbon emissions; Promote new flame retardant core materials such as phenolic resin.
Customized services
Support personalized customer needs, such as special board shapes (flat, corrugated), coatings, and color customization.
