How to safely store polyether polyols: chemical industry storage points

Polyether polyols (Polyether polyols) are widely used in the chemical industry as basic raw materials, commonly used in the production of polyurethane foams, elastomers, coatings and other products. Due to the particularity of its chemical properties and use environment, how to safely store polyether polyols has become a problem that chemical companies must pay attention. This article will analyze in detail how to safely store polyether polyols to ensure the safety of chemical plant operations and the stability of raw materials.

1. Polyether polyol storage environment requirements

The storage environment of polyether polyols is critical to their safety. Polyether polyols should be stored in a cool, dry, well-ventilated place. Excessive temperature may cause its decomposition or chemical reaction, affecting product quality. The storage temperature should generally be controlled between 15°C and 35°C. Avoid exposing it to sunlight, as UV rays may cause changes in chemical composition.

Keep polyether polyols away from open flames, heat sources or flammable materials. Although polyether polyols are not inherently highly flammable, they may produce volatiles or initiate other dangerous reactions at elevated temperatures or under conditions of improper storage. Therefore, the storage site should be equipped with fire extinguishers and other fire fighting facilities, and ensure that operators are familiar with emergency treatment measures.

2. Storage container selection and maintenance

How to safely store polyether polyols, container selection and maintenance can not be ignored. Polyether polyols are usually stored in sealed containers to prevent the influence of moisture in the air. The presence of moisture may cause the polyether polyol to undergo hydrolysis reactions, reducing its performance. Therefore, it is necessary to choose a metal or plastic container with good sealing performance.

In the selection of storage containers, should be based on the characteristics of polyether polyol, choose corrosion resistance, not easy to leak material. Regularly check the container for damage, leakage and other problems to ensure its safety. Especially for large-volume storage, it must be ensured that the container is intact and equipped with appropriate pressure relief devices to prevent overpressure inside the container.

3. Avoid contamination and cross-reaction

Polyether polyols are susceptible to external contamination, so cross-contamination with other chemicals must be avoided when storing polyether polyols safely. Especially in the storage area, it is necessary to ensure that polyether polyols are stored separately from strong corrosive substances such as acids and alkalis to avoid reactions or safety accidents.

The storage area should be strictly cleaned and managed to prevent dust and impurities from entering the container. When handling polyether polyols, operators must wear protective equipment to avoid chemical contact with skin or eyes.

4. Storage temperature and humidity monitoring

How to safely store polyether polyols also requires real-time monitoring of the temperature and humidity of the storage environment. Excessive humidity may cause the polyether polyol to absorb water, causing a change in quality. If the temperature is too low, the viscosity may increase and affect the subsequent use.

Therefore, the storage facilities should be equipped with temperature and humidity monitoring system, timely adjustment of environmental conditions. Through the data recording instrument, the temperature and humidity change trend can be tracked to ensure that the storage environment is in an ideal state.

5. Compliance with safety regulations and regular training

Storage of polyether polyols is not only the control of the physical environment, but also the operation of personnel. How to safely store polyether polyols requires operators to comply with a strict safety management system. All personnel involved in the storage, handling and use of polyether polyols should receive regular safety training on the nature of the chemical, storage requirements and emergency handling.

Enterprises should formulate emergency plans to ensure that they can respond in time and take effective measures in case of leakage, fire and other emergencies.

Conclusion

How to safely store polyether polyols is an important issue that cannot be ignored in the chemical industry. By properly controlling the storage environment, selecting appropriate storage containers, avoiding cross-contamination, monitoring temperature and humidity, and strengthening personnel training, risks can be minimized to ensure the safe storage and use of polyether polyols. Only by strictly complying with these safety regulations can chemical enterprises ensure safety and stability in the production process.
