The production and application of pir sandwich panel

PIR sandwich panel is a high-performance building panel consisting of polyisocyanate (PIR) foam and two panels. This kind of board has excellent thermal insulation performance, fire performance, durability and light weight characteristics, and is widely used in construction, furniture, aerospace, automobile and other fields.

The production process of PIR sandwich panel includes the following steps:

1. Foam production

PIR foam is the core material of PIR sandwich panel. Its production process needs to use raw materials such as isocyanate and polyether to produce foam through chemical reaction. In the production process, parameters such as density, hardness, and expansion rate of foamed plastics need to be controlled to ensure that the final sandwich panel has stable performance.

2. Panel production

The panels of PIR sandwich panels can be made of different materials, such as steel plates, aluminum plates, color steel plates, etc. During the panel production process, the panels need to be painted, processed, shaped, etc. to meet different application requirements.

3. Sandwich panel production

Sandwich panels are made by bonding foam and two panels together to form a sandwich structure. During the production process, parameters such as the amount of adhesive used, pressure, and temperature need to be controlled to ensure the quality and performance of the sandwich panels.

PIR sandwich panels have a wide range of application fields, mainly including the following aspects:

1. Construction field

PIR sandwich panels can be used as building materials such as walls, roofs, heat insulation boards, etc., and have excellent thermal insulation performance and fire protection performance. PIR sandwich panels are widely used in industrial plants, commercial buildings, cold storage and other places.

2. Furniture field

PIR sandwich panels can be used as furniture materials, such as door panels, cabinets, etc. Due to its lightweight characteristics, it can reduce the weight of furniture, and at the same time it has the properties of moisture-proof, anti-corrosion, and durability.

3. Aerospace field

PIR sandwich panels can be used as structural materials for aerospace equipment such as aircrafts and rockets, and have the characteristics of light weight, high strength, and corrosion resistance.

4. Automotive field

PIR sandwich panels can be used as materials for car bodies, doors, roofs and other components, and have the characteristics of light weight, sound insulation, and heat preservation.

In conclusion, as a high-performance material, PIR sandwich panel has broad application prospects. With the development of science and technology and the continuous expansion of application fields, the production and application of PIR sandwich panels will receive more extensive attention and application.
