Cold Storage Panels

The production of cold storage panels is a complex and delicate process. Henan Panels Industry Co.,Ltd. first selects high-quality color steel plates as panel materials. These color steel plates undergo strict pretreatment, including degreasing, cleaning and chemical conversion treatment, to enhance their corrosion resistance and coating adhesion.

The choice of core material is also crucial. The company usually uses materials such as polyurethane (PU) or rock wool with excellent thermal insulation performance. For the processing of core materials, precise cutting and shaping are required to ensure perfect fit with the panel.

During the composite process, the panel and core material are bonded under high temperature and high pressure through an advanced automated production line, so that the two are closely combined to form a solid whole. This process not only ensures the structural strength of the sandwich panel, but also ensures good thermal insulation and air tightness.

Finally, after strict quality inspections, including appearance inspection, dimension measurement, thermal insulation performance test and fire performance evaluation, only products that meet the standards can be delivered for use.

1. Insulation performance: The thermal conductivity is usually between 0.018 - 0.028 W/(m·K), which can effectively prevent heat transfer and ensure stable temperature in the cold storage.

2. Fireproof performance: It meets the national fireproof level, such as B1, B2, etc., and has good flame retardant effect.

3. Compressive strength: Generally between 150 - 300 kPa, and can withstand greater pressure.

4. Airtightness: The air permeability is less than 0.05 m³/(m²·h), which effectively reduces the loss of cold.

5. Dimensional stability: The deviation of length and width is controlled within ±2mm, and the thickness deviation is within ±1mm to ensure installation accuracy.

6. Service life: Under normal use and maintenance conditions, it can be used for 15 - 25 years.

1. Panel pretreatment process: Strict degreasing, cleaning and chemical conversion treatment can significantly improve the corrosion resistance of color steel plates, extend the service life of sandwich panels, and make them less likely to rust and damage in the humid environment of cold storage.

2. Selection and processing of core materials: The low thermal conductivity of high-quality insulation core materials such as polyurethane determines the excellent insulation performance of the sandwich panel and reduces the energy consumption of the cold storage. Precise cutting and shaping of the core material ensures a close fit with the panel, avoids the occurrence of cold bridges, and further improves the thermal insulation effect.

3. Composite process: The high-temperature and high-pressure composite process forms a strong bond between the panel and the core material, which enhances the overall structural strength of the sandwich panel and enables it to withstand the pressure of heavy objects inside the cold storage and the impact of the external environment. At the same time, Good bonding also helps maintain airtight properties.

4. Control of technical parameters: Strict control of dimensional deviations ensures the splicing accuracy of the sandwich panels during installation, reduces gaps, and improves air-tightness and thermal insulation performance. Reasonable compressive strength design ensures the stability of the sandwich panel during use and is not easily deformed.

1. Excellent thermal insulation

The cold storage panels of Henan Panels Industry Co.,Ltd. use high-quality thermal insulation core materials, have excellent thermal insulation performance, greatly reduce the heat exchange inside and outside the cold storage, reduce energy consumption, and save you operating costs.

2. High strength and stable structure

After careful design and manufacturing, the sandwich panels have strong compression and bending resistance, can withstand the accumulation of heavy objects inside the cold storage and the pressure of the external environment, and ensure the long-term stable operation of the cold storage.

3. Excellent fireproof performance

The use of materials with high fireproof grades can effectively delay the spread of fire, provide reliable protection for the safety of the cold storage, and reduce the risk of fire.

4. Good airtightness and moisture-proof

The tight sealing structure and moisture-proof treatment prevent water vapor penetration and air leakage, maintain a dry environment in the cold storage, and are conducive to the storage quality of goods.

5. Corrosion resistance and durability

The surface is made of specially treated color steel plates, which have excellent corrosion resistance, can resist erosion in various harsh environments, and extend the service life.

6. Flexible customization
