Storage precautions for porous magnesium rings

　　Porous magnesium rings, as a special type of metallic material, are widely used in industries and medical fields. Due to their unique physical structure and chemical properties, careful attention must be paid to environmental conditions during storage to ensure the material's performance remains unaffected.

　　Storage Environment Requirements

　　Porous magnesium rings have strict requirements for their storage environment, necessitating careful attention to factors such as humidity, temperature, and light exposure. The relative humidity in the storage area should be kept below 65%, and materials should never be stored outdoors or left exposed directly to rainwater or dew. If the warehouse floor is concrete, it’s essential to lay down a moisture-proof underlayment to prevent ground moisture from affecting the material. In terms of temperature, it’s recommended to maintain conditions between -5°C and 35°C, avoiding prolonged exposure to high temperatures (above 40°C) or repeated freeze-thaw cycles (below -10°C). High temperatures can accelerate the aging of the surface oxide layer, while low temperatures combined with moisture may lead to condensation or even ice formation on the surface—both of which can cause corrosion once melted. Warehouses should ensure natural ventilation while minimizing direct exposure to strong winds. Additionally, direct sunlight should be avoided. If temporary outdoor storage is unavoidable for up to 72 hours, materials must be carefully covered with a double layer of shade cloth and waterproof tarpaulin to protect them from both sun and rain.

　　Moisture-proof and Corrosion-resistant Measures

　　Moisture-proof treatment is crucial for porous magnesium rings. During storage, use packaging materials with excellent sealing properties, and regularly inspect containers to ensure they are free from air leaks or damage. After opening a used package, reseal it promptly to prevent air from entering and causing oxidation. Additionally, consider placing desiccants like calcium oxide in the storage area to effectively reduce humidity levels. Always keep the product away from salt and corrosive gases, and strictly prohibit storing it near seawater, saline solutions, de-icing agents, or acidic/alkaline substances. If the project site is located in a coastal area with high salt content, the warehouse must have robust sealing and moisture-proof capabilities—and if necessary, install desiccants inside the warehouse to further minimize airborne salt concentrations.

　　Safety Precautions

　　When storing porous magnesium rings, special attention must be paid to safety precautions. The material should be kept away from ignition sources and flammable items, and direct contact with open flames or high temperatures must be avoided. Clearly visible safety warning signs should be posted in the warehouse to remind staff to prioritize fire safety. Additionally, avoid contact with certain chemicals that could trigger reactions, potentially leading to explosions or the release of hazardous gases. It’s also important to manage storage duration carefully—long-term storage can degrade the material’s performance. As a general guideline, it’s recommended to store the material for no more than one year, and inventory should be managed on a first-in, first-out basis.

　　Consequences of Improper Storage

　　If stored improperly, porous magnesium rings may encounter several issues. Exposure to moisture can lead to oxidative corrosion on the material's surface, forming a loose, porous oxide layer that degrades its performance. High-temperature environments may pose a risk of spontaneous combustion, especially when the material has a large surface area. Contact with corrosive substances can cause localized surface corrosion, compromising the material's functionality. In extreme cases, improper storage could even trigger safety hazards, such as dust explosions. Therefore, adhering strictly to proper storage guidelines for porous magnesium rings is essential for maintaining both material integrity and user safety.
