Summary of common problems of Polyurethane Cold Room board


1. Knowledge summary of Polyurethane Cold Room board

Polyurethane color steel plate can also be used as a Polyurethane Cold Room plate, but most of the cold storage plates are different from them in that the lock catch is embedded in the plate. During the installation and use, the lock catch embedded in the internal and external slots of the two plates is overlapped with each other.

2. Price of Polyurethane Cold Room board

Price calculation of Polyurethane Cold Room plate: first, calculate the price per square meter of color steel plate on both sides, and then add the price per square meter of the polyurethane core material. The price of the color steel plate is based on the steel plate used, the required thickness, and other special requirements for the surface spraying of the color steel plate.


3. Installation and construction process of Polyurethane Cold Room board wall panel

The installation of the Polyurethane Cold Room panel wall panel shall be in strict accordance with the installation specifications and the layout drawing. During the installation, the Polyurethane Cold Room panel wall panel shall be properly cut at the processing site, the panel film about 5cm on both sides of the concave-convex groove of the cold storage panel shall be removed, and the inner side of the groove shall be treated with a continuous sealant.


4. Installation and construction process of Polyurethane Cold Room board and ceiling board

The ceiling board of the Polyurethane Cold Room board is hung by steel purlin. In order to ensure the integrity of the roof board and avoid cutting Polyurethane Cold Room board as much as possible, the width and size of each cold storage board shall correspond to the pipeline or hanging position on the top of the cold storage.


5. What are the main raw materials of polyurethane rigid foam used in the Polyurethane Cold Room board produced by color steel?

In most cases, there are two kinds of raw materials used in the production of rigid foam. One is an isocyanate. The commonly used isocyanate is polyphenylmethane polyisocyanate. Its functionality is generally between 2.5 and 3.2. It is also identified as MDI or Papi, commonly known as "black material".


6. Polyurethane Cold Room plate

Cold storage insulation board mainly includes Polyurethane Cold Room board, rock wool cold storage board, polystyrene cold storage board, glass wool cold storage board, etc.


7. Polyurethane Cold Room board installation

The lapping of the wall panel and the top plate, the reinforcement of the wall panel and the steel frame, and the hoisting of the ceiling panel and the frame are all equipped with special combined accessories and special forms to ensure the airtight, firm and safe insulation of the cold storage. High strength locks are embedded around each precast slab, which is very convenient for assembly.


8. Characteristics of Polyurethane Cold Room board

Features of Polyurethane Cold Room board: concave-convex groove structure improves the insulation and airtightness of the board joint, which is specially designed for the cold storage room and warehouse. The board is even and stable, with excellent heat insulation and waterproof performance.
