1. Water absorption‌: Rock wool cold storage board has high water absorption. When it is damp or soaked, it is easy to deform, resulting in a decrease in its thermal insulation performance.

 

‌2. Poor stress performance‌: Compared with other insulation materials, rock wool cold storage board has lower strength and rigidity, and is easily deformed and cracked by stress, affecting its service life.

 

‌3. Poor durability‌: Due to the high water absorption and easy deformation characteristics of rock wool cold storage board, it is easy to lose its thermal insulation performance due to moisture, mildew and aging during long-term use.

 

‌4. Fiber shedding‌: During the production, transportation, and installation process, the rock wool cold storage board will produce fiber shedding, which may irritate human health and even cause respiratory problems.

 

‌5. High density‌: The density of rock wool cold storage board is relatively large and the weight is heavy, which increases the difficulty and cost of installation.

 

‌6. Environmental pollution‌: The production process of rock wool cold storage panels involves ore mining, high-temperature smelting, and other links, which will produce a large number of pollutants such as sulfur dioxide, causing certain pressure on the environment‌.
