1. Storage Requirements
(1) Environmental Control
Moisture-proof sealing:
Electrolytic manganese flakes are very easy to oxidize, so they must be sealed with vacuum packaging or filled with nitrogen/argon to insulate air and moisture.
Temperature and humidity:
The recommended storage temperature is ≤30°C, relative humidity <60% (temperature and humidity monitor must be installed).
Avoid light and ventilation:
Avoid direct sunlight, the warehouse should be ventilated to prevent the formation of hydrogen (H₂) or acid gases.
(2) Stacking Specification
Pallet separation:
Packaging boxes should be placed on wooden or plastic pallets, ≥15 cm from the ground, avoiding direct contact with wet ground.
Stack height:
The height of one stack is no more than 3 layers to prevent the bottom layer of the package from collapsing under pressure.
Zone storage:
Acids and oxidizing agents (such as ammonium nitrate and chlorate) should be stored separately or at ≥5 m intervals.
2. Transport Characteristics
(1) Packing Standard
Inner layer: vacuum bag made of aluminum foil or aluminum film, moisture-proof and resistant to oxidation.
Middle layer: Impact-resistant foam or bubble wrap to reduce collisions during transportation.
Outer layer: strong corrugated cardboard or wooden box marked with the signs "moisture resistant" and "fragile".
(2) Transportation Method
Ground Transportation:
Choose van-type trucks to avoid open-air transportation; Use refrigerators (temperature control ≤35°C) during the summer high temperature.
Sea transport:
Place a desiccant (such as silica gel) inside the container; The container must be airtight and regularly checked for humidity.
Anti-vibration measures:
Use anti-slip pads to secure between containers to avoid strong impacts that cause the manganese flakes to break.
(3) Multimodal Transport Ban
The following substances may not be carried in the same vehicle:
Acids (e.g., sulfuric acid, hydrochloric acid) → The reaction releases hydrogen, which is flammable and explosive.
Oxidizing substances (e.g., peroxides, nitrates) can → cause violent oxidation reactions.
Water-containing products (e.g. liquid chemicals) do → increase the risk of moisture ingress.
