FRP Gel-coated PANEL in Cold Storage

Product 

Innovative application and advantages of FRP gel-coated PANEL in cold storage As a high-performance composite material, FRP gel-coated board (FRP gel-coated board) shows unique application value in cold storage construction. It uses unsaturated polyester resin as the matrix, glass fiber as the reinforcing material, and a gel-coated layer on the surface to form a composite board with both functionality and durability, becoming the preferred material in the field of modern cold chain storage.

1Core performance adapted to the harsh environment of cold storage Excellent thermal insulation performance: The thermal conductivity is as low as 0.25W/(m·K), which effectively blocks the exchange of cold and heat, saves more than 30% energy compared with traditional metal plates, and significantly reduces the load of refrigeration equipment. Anti-condensation properties: The surface gel coat layer forms a dense protective film, which keeps the surface dry at a low temperature of -40℃, avoiding frost problems caused by accumulation of condensed water. Structural stability: The thermal expansion coefficient is close to that of steel (11×10^-6/℃), and the size remains stable when the temperature fluctuates violently, eliminating the risk of cracking in the joints.

2 Innovative application scenario expansion Three-dimensional cold storage wall panel system: adopts a 12mm thick double-layer hollow structure design, filled with polyurethane foam inside, to achieve integrated wall insulation, and improve construction efficiency by 50%. Special board for clean cold storage: FDA-certified food-grade gel coat surface, combined with antibacterial additives, to meet the microbial control requirements of medicine and fresh food storage. Automated cold storage components: Anti-static boards with pre-embedded conductive fibers are used in AGV channels, with a surface resistance stable at 10^6~10^9Ω, to ensure the safe operation of automated equipment.

Core application advantages of FRP gel-coated board in cold storage

1. Principle of achieving excellent thermal insulation performance

The closed-cell polyurethane sandwich structure and FRP composite process greatly inhibit thermal conductivity. The closed-cell structure forms many independent small spaces, effectively preventing heat transfer; the composite process allows various materials to work together to enhance the thermal insulation effect. The material density is about 1.8g/cm³, and the thickness is 1.0 - 4.0mm and can be adjusted as needed. Used in cold storage, it can significantly reduce energy consumption, such as saving about 20% of electricity per year in a small cold storage.

2. Corrosion resistance, moisture resistance and mildew resistance

The gel coat layer is like a solid shield, resisting the erosion of acid and alkali media and condensed water. It is dense and smooth, and it is difficult for acid and alkali substances to adhere and penetrate, and condensed water will also slide off. The surface finish reaches Ra0.8μm and is easy to clean. In places with high requirements for cleanliness such as food processing plants and pharmaceutical cold storage, it can keep the environment in the warehouse clean and reduce mold growth.
