Introduction to Polyurethane Cam Lock Cold Storage Panels

                                                                     

I. Structure and Composition

Polyurethane cam lock cold storage panels mainly consist of a three-layer structure. The outer layer is usually a metal panel, commonly including colored steel plates, galvanized steel plates, or stainless steel plates. These metal panels not only provide good strength and durability but also possess certain aesthetic appeal and corrosion resistance. The inner layer is also a metal panel, which serves to protect and support the intermediate insulation layer. The core layer in the middle is a polyurethane insulation material, a foamed material made through a special formula and process. It has an extremely low thermal conductivity, which can effectively prevent heat transfer and maintain the low-temperature environment inside the cold storage.

II. Performance Characteristics

 

1. Excellent Thermal Insulation Performance: Polyurethane material itself has outstanding thermal insulation properties. Its thermal conductivity can be as low as 0.02 - 0.025 W/(m·K). This enables the cold storage panels to significantly reduce heat exchange, lower the energy consumption of the cold storage, and provide a stable low-temperature environment for the stored items.
2. Good Sealing Performance: The design of the cam lock allows the cold storage panels to be closely connected, forming a good sealing effect. This sealing performance can not only prevent heat leakage but also effectively block the entry of moisture, dust, and air, maintaining the cleanliness and dryness inside the cold storage.
3. High Strength and Stability: The combination of the metal panel and the polyurethane insulation layer endows the cold storage panels with high strength and stability. They can withstand a certain amount of pressure and weight without deforming easily, making them suitable for the construction of various cold storages, including multi-story cold storages and large-scale warehousing cold storages.
4. Fire Resistance: Some polyurethane cam lock cold storage panels are added with flame retardants during the production process, giving them certain fire resistance. When a fire occurs, they can delay the spread of the fire, buying time for personnel evacuation and fire fighting.
5. Easy Installation: The connection method of the cam lock is simple and quick, requiring no complex tools or techniques. Installers can quickly assemble the cold storage panels together, greatly shortening the construction period of the cold storage.

III. Cam Lock Connection Method

The cam lock is a key connecting component of the polyurethane cam lock cold storage panels. It consists of parts such as the cam, the lock catch, and the fixing device. During the installation process, align the two adjacent cold storage panels, and then rotate the cam to make the lock catch bite tightly together, thus achieving a firm connection between the cold storage panels. This connection method is not only easy to operate but also has a high connection strength, ensuring stability during the long-term use of the cold storage.

IV. Specifications and Customization

Polyurethane cam lock cold storage panels are available in a variety of standard specifications. Their thickness usually ranges from 50mm to 200mm, the width is generally between 1000mm and 1200mm, and the length can be customized according to actual needs. In addition, customized production can also be carried out according to the special requirements of customers, such as different panel materials, colors, and insulation performances, to meet the personalized needs of various cold storage projects.

V. Application Fields

 

1. Food Industry: Widely used in the construction of food cold storages, such as the refrigerated and frozen storage of meat, seafood, fruits, vegetables, and other foods. It can ensure the freshness and quality of food and extend the shelf life of food.
2. Pharmaceutical Industry: Used in the construction of pharmaceutical cold storages to provide a strictly temperature-controlled environment for the storage of drugs, vaccines, etc., ensuring the quality and effectiveness of drugs.
3. Chemical Industry: Can be used for the low-temperature storage of chemical raw materials and products. Some temperature-sensitive chemical products need to be stored in a specific low-temperature environment, and polyurethane cam lock cold storage panels can meet this requirement.
4. Logistics and Warehousing: In logistics warehouses, it is used to build low-temperature storage areas, improving the efficiency of logistics warehousing and the storage quality of goods.
