How to storage the polyether polyols?
Containers for polyether polyols can be made of steel, aluminum, polyethylene or polypropylene.
The storage temperature should not exceed 70℃.
To prevent moisture absorption and oxidation, it is recommended that the container be filled with nitrogen. Not subject to storage rules for flammable liquids, but should avoid entering groundwater or surface water as it is not easily biodegradable.
Generally, the toxicity of neutral polyether polyols when ingested into the mouth or in contact with skin, eyes, or mucous membranes is negligible, so personal protective measures are not necessary during use.
Amino polyether polyols can irritate skin and eyes due to their alkalinity, so safety glasses, gloves and other protective equipment must be worn during operation.
Storage of polyether polyols is crucial to maintain their quality and prevent degradation over time. Here are some guidelines for proper storage:
1. Temperature Control:
- Store polyether polyols in a cool and dry environment.
- Avoid exposure to extreme temperatures, as both high heat and freezing conditions can negatively impact the polyol's stability and performance.
2. Ventilation:
- Ensure good ventilation in the storage area to prevent the accumulation of vapors.
- Store polyether polyols away from direct sunlight and heat sources.
3. Container Handling:
- Use containers made of materials compatible with polyether polyols, such as stainless steel or high-density polyethylene (HDPE).
- Keep containers tightly sealed to prevent moisture absorption and contamination.
- Minimize headspace in containers to reduce the risk of oxidation.
4. Avoid Contamination:
- Prevent the ingress of moisture, air, and contaminants by using dedicated equipment for transferring and handling polyether polyols.
- Use clean, dry equipment during the transfer process.
5. Inert Gas Blanketing:
- Consider using inert gas (such as nitrogen) blanketing to displace air in storage containers, minimizing the risk of oxidation.
6. Storage Duration:
- Adhere to the recommended shelf life provided by the manufacturer.
- Use a first-in, first-out (FIFO) inventory system to ensure older stock is used before newer batches.
7. Handling Procedures:
- Avoid unnecessary exposure to air during handling and transfer.
- Use appropriate pumps and hoses to minimize contact with the atmosphere.
8. Monitoring and Testing:
- Periodically check the condition of stored polyether polyols.
- Perform routine testing for key properties, such as hydroxyl number and viscosity, to ensure they meet specifications.
9. Safety Measures:
- Follow proper safety guidelines and regulations for handling and storing chemicals.
- Keep storage areas well-lit and equipped with emergency response equipment.
