The key points for storing hydrated alumina are to prevent moisture, light, and high temperatures to ensure its physicochemical stability.
Sealing and Moisture Protection: It must be stored in a sealed container to prevent moisture absorption, clumping, or phase change. The packaging should be intact, and exposure to humid air should be avoided.
Light Protection: It needs to be stored in the dark to prevent heat accumulation or photochemical reactions that could affect its stability.
Environmental Requirements: It should be stored in a dry, cool, and well-ventilated warehouse. The relative humidity is recommended to be below 60% to prevent dust accumulation.
Temperature Management: The recommended storage temperature is no higher than 40℃. Keep away from heat sources, as heating above 200℃ may cause dehydration, and significant decomposition is possible at 300℃.
Safety Precautions: Although not classified as a hazardous material, prolonged inhalation of dust may irritate the respiratory tract. The operating area should be kept clean, and local exhaust ventilation or wearing protective masks should be provided if necessary.
Compatibility Note: Avoid coexistence with incompatible substances such as strong acids to prevent violent reactions.
