Cold storage spray insulation materials typically refer to rigid polyurethane foam spray materials. In modern cold chain logistics and high-standard cold storage construction, they have become the preferred solution for many food and pharmaceutical cold storages, thanks to their excellent thermal insulation performance, superior sealing properties, and seamless forming characteristics.
In terms of material properties, high-quality polyurethane spray materials feature an extremely low thermal conductivity (typically between 0.018-0.024 W/(m·K)), which effectively blocks heat exchange between the interior and exterior. Meanwhile, their closed-cell ratio reaches as high as 90% or even above 95%, not only providing excellent moisture resistance and water vapor barrier capabilities but also offering the advantage of integrated thermal insulation, waterproofing, and corrosion protection. Furthermore, this material exhibits strong adhesion, bonding firmly to various substrates such as concrete, steel, and masonry, forming a continuous, seamless insulating shell that effectively avoids the "thermal bridge" effect commonly associated with traditional insulation materials.
In terms of construction technology, polyurethane spraying uses professional high-pressure impingement mixing foaming machines for on-site foaming. During construction, isocyanate (black material) and polyether polyol blend (white material) are rapidly mixed through high-pressure equipment and directly sprayed onto the cold storage walls or ceilings, instantly foaming and forming. This on-site foaming method adapts to various complex building structures and irregular surfaces, eliminating the need for expensive mold costs. The standard spraying process includes: cleaning the substrate, applying a moisture-proof primer, multi-layer polyurethane spraying (typically each layer about 20mm thick, with multiple passes to prevent cracking and delamination), followed by curing and quality inspection.
However, cold storage spray insulation is a systematic project highly dependent on professional expertise, and its final effect is influenced by many factors. First are the environmental requirements: during construction, the ambient temperature and substrate surface temperature typically need to be above 5°C, and the surface must remain dry, free of oil, and dust; otherwise, it may lead to overall delamination of the insulation layer or the formation of voids. Second is the matching of raw materials and equipment: selecting imported or top-tier domestic raw materials (such as Wanhua, BASF) combined with high-pressure spraying equipment is key to controlling foam flatness, density (typically ≥40kg/m³ for walls), and flame retardancy rating.
In summary, cold storage spray insulation materials not only perform excellently in physical properties but also significantly reduce the long-term operational energy consumption of cold storage. However, in practical applications, enterprises must choose a team with professional qualifications, the use of authentic raw materials, and extensive construction experience. Only by combining high-quality materials with standardized construction techniques can a truly energy-efficient, durable, and modern cold storage insulation project be achieved.
