The main reason why the coated salt-treated board is used in cold storage panels is its excellent moisture-proof, anti-corrosion and thermal insulation properties. The surface of the coated salt-treated board has a special moisture-proof coating, which can effectively prevent moisture penetration and mold growth, and extend the service life of the cold storage. At the same time, it contains salt substances inside, has good corrosion resistance, and can maintain structural stability in low temperature environments. In addition, the coated salt-treated board also has excellent thermal insulation effect, which can effectively isolate external temperature changes and ensure a constant temperature environment inside the cold storage, thereby saving energy and operating costs.
