Cold chain insulation material – polyurethane cold storage board
With the rapid development of the cold chain logistics industry, the demand for cold storage construction continues to grow. As the core facility of the cold chain system, the insulation performance of the cold storage is directly related to energy consumption, storage efficiency and operating costs. Among the many cold chain insulation materials, polyurethane cold storage board has become the preferred material for cold storage construction due to its excellent insulation, stability and economy.
1. Insulation core of cold storage construction
Polyurethane cold storage board is a composite board with polyurethane foam as the core sandwich, which achieves efficient insulation through high-density structure. Its core advantages are reflected in the following aspects:
Ultra-low thermal conductivity, significant energy-saving effect
The thermal conductivity of polyurethane is as low as 0.022 W/(m·K), which is better than traditional materials such as polystyrene. It can reduce heat exchange inside and outside the cold storage and reduce energy consumption by more than 30%. This is crucial for cold storage that needs to maintain a temperature of -18℃ or even lower for a long time, directly shortening the operation time of the refrigeration unit and saving electricity costs.
Integrated structure, efficient and convenient construction
The polyurethane cold storage panel adopts a prefabricated assembly design, and the panels are seamlessly spliced, which greatly shortens the construction period of the cold storage. At the same time, its high-strength compressive strength (compressive strength ≥1.0 MPa) can withstand the load of stacking and equipment vibration, avoiding the crack problem that may occur in traditional on-site pouring.
Double protection of fire prevention and environmental protection
The polyurethane cold storage board of Canglong Group adopts B1 grade fireproof material, which meets the national fire protection standards and effectively improves the safety of cold storage. In addition, the material does not contain harmful substances such as CFCs, taking into account environmental protection and sustainable development needs.
2. How to choose high-quality polyurethane cold storage board?
The construction of cold storage needs to comprehensively consider temperature requirements, storage categories and budgets, and the performance parameters of polyurethane cold storage panels directly affect the success or failure of the project:
Board thickness and density matching requirements
The lower the temperature of the cold storage, the higher the requirement for board thickness. For example, -30℃ low temperature storage usually uses polyurethane cold storage panels with a thickness of more than 100mm to ensure that the loss of cold capacity is minimized. Canglong Group provides a full range of customized panels with a thickness of 50-200mm to meet the needs of different scenarios.
Equal emphasis on fire protection level and structural stability
For large projects such as cold chain logistics parks, Canglong Group uses a continuous production line to ensure uniform density of the panels (≥40kg/m³), and is equipped with a metal surface protection layer, which has both impact resistance and fire resistance.
Installation process determines long-term benefits
Canglong Group is equipped with a professional construction team, using lock-type splicing technology to avoid cold bridges, and supplemented by air tightness testing to ensure the overall sealing of the cold storage and extend its service life.
3. The core difficulties of cold storage construction
In the operating costs of cold storage, energy consumption accounts for as much as 30%-50%. If the performance of the insulation material is insufficient, it will not only lead to rising electricity bills, but also may affect the quality of stored items due to temperature fluctuations, and even cause safety hazards.
Canglong Group’s polyurethane cold storage board solves industry problems through three major technological breakthroughs:
Ultra-low thermal bridge design: The metal panel and the polyurethane core material are tightly bonded to reduce the conduction of cold air.
Dynamic temperature control adaptability: Supports the rapid response needs of automated cold storage.
Long-term maintenance cost is low: Anti-mildew and anti-aging properties reduce the frequency of maintenance.
