PIR sandwich panel supplier

The cold storage sandwich panels are generally refers to the PU/PIR sandwich panels,which has best thermal insulation performance,are widely used in various low-temperature roofs and walls.   Common applications as below:   1. Various cold storage systems: ambient temperature cold storage, low temperature freezing storage, constant temperature and humidity warehouses, pre-prepared food warehouses and kitchens, etc.   2. Food factories and workshops: fruit and vegetable preservation and processing workshops, poultry slaughterhouses, aquatic product processing workshops;   3. Various cold chain logistics warehouses: logistics park cold storage, ambient temperature cold chain warehouses, low temperature cold chain warehouses, cold chain distribution centers, etc.   4. Agricultural products and aquaculture: crop seed storage warehouses, low temperature mushroom storage warehouses, agricultural product storage warehouses; low temperature aquatic and seafood storage warehouses, etc.;   5. Pharmaceuticals and chemicals: vaccine cold storage, pharmaceutical storage cold storage, low temperature sterile laboratories, biobanks, low temperature chemical storage, explosion-proof cold storage, etc.;   6. Commercial and mobile cold storage: container mobile cold storage, refrigerated trucks, supermarket cold storage rooms, frozen warehouses, etc.

Insulated wall panels are composite wall panels made of two layers of rigid plates (such as metal plates, cement plates, etc.) and one layer of insulation core material (such as EPS, PU, rock wool, glass wool, aluminum honeycomb, etc.).   Traditional walls are generally made of bricks and cement mortar or poured concrete.   The specific differences between the two are as follows:   1. Construction methods: Insulated wall panels can be directly installed on steel structures without additional insulation; traditional wall have complex construction processes, requiring separate insulation after the wall is built.   2. Construction cycles: Insulated wall panels are integrated panels that can be directly installed; the construction cycle is short, generally about 4 weeks for a small factory to complete installation; traditional wall have complex construction processes and a long construction period, generally several months for a small factory to complete.   3. Weight: Insulated wall panels are generally lighter, suitable for light steel structures and renovation of old houses; traditional wall are very heavy, placing high demands on the load-bearing capacity of the foundation and beams.   4. Significant differences in thermal insulation performance: The core material of insulated wall panels is a high-insulation material, providing excellent insulation; traditional wall, being cement concrete, have poor insulation performance and require separate insulation.   5. Structural strength and waterproofing performance: Insulated wall panels have waterproofing treatment at the joints, resulting in better waterproofing and wind resistance; the insulation layer of traditional wall is prone to peeling off, and inadequate waterproofing can easily lead to water seepage and cracking.   6. Different application scenarios: Insulated wall panels are mostly used in prefabricated modular houses, steel structure factories, large warehouses, clean rooms, cold storage, etc.; traditional wall are mainly used in residential buildings.

The Sandwich panels are widely used in food processing factories due to their excellent thermal insulation, good moisture and water resistance, corrosion resistance, and excellent fire resistance.     1. Excellent thermal insulation performance. Generally, the thermal conductivity of PU/PIR sandwich panels is between 0.020 and 0.024 [W/(m·K)], providing good thermal insulation and effectively controlling indoor and outdoor temperatures to ensure food freshness.   2. Seamless splicing during assembly ensures good sealing, reducing the risk of bacteria and mold growth and enabling dust-free workshops.   3. The core material used in sandwich panels has a high closed-cell rate, is non-absorbent, and offers excellent waterproof and moisture-proof performance, ensuring food freshness.   4. The color-coated steel plates used in sandwich panels have high structural strength, strong load-bearing capacity, and good corrosion resistance.   5. Sandwich panels generally have a fire rating of B1 (PIR sandwich panels) or A (rock wool sandwich panels), offering excellent fire resistance and making them more suitable for high-temperature food processing workshops;   6. Sandwich panels are produced in modular form, requiring only on-site installation and splicing, resulting in simple construction, short construction period, less dust, and high cost-effectiveness.
