一. Storage and handling precautions
1. Sealing and moisture-proof
o Pseudo-boehmite is easy to absorb moisture. Exposure to a humid environment may cause caking or performance degradation.
o Double-layer sealed bags or moisture-proof containers should be used for storage and placed in a dry and cool place.
o If the material is not used up after opening, it needs to be resealed and stored in a desiccator.
2. Avoid high temperature and direct sunlight
o Long-term high temperature environment may affect its structural stability. The storage temperature is recommended to be controlled at room temperature (below 25°C).
3. Handling specifications
o Use dry tools when handling, avoid direct contact with hands, and prevent sweat or grease contamination.
o If the material has been damp, it can be dried at 80-100°C for 2-4 hours to restore some performance.
二. Safety protection during operation
1. Personal protection
o Respiratory protection: Pseudo-boehmite powder may generate dust, so wear a dust mask (N95 or higher) when operating.
o Eye protection: Wear goggles to prevent powder from splashing into the eyes.
o Skin protection: Wear a lab coat and dust-proof gloves (such as nitrile gloves) to avoid direct contact.
2. Environmental control
o Operate in a fume hood or well-ventilated environment to avoid dust accumulation.
o If high-temperature treatment (such as roasting) is performed, ensure that the equipment is well ventilated to prevent the accumulation of harmful gases.
3. Prevent static electricity hazards
o Powdered pseudo-boehmite may generate static electricity in a dry environment, so avoid using it in a flammable and explosive environment when operating.
三. Waste disposal and emergency measures
1. Waste disposal
o Pseudo-boehmite itself is non-toxic, but if it contains heavy metals or other pollutants, it must be treated as hazardous waste.
o Waste powder should be collected in a sealed container and handed over to a professional organization for disposal to avoid random dumping.
2. Emergency treatment
o Inhalation of dust: immediately move to a place with fresh air. If you feel unwell, seek medical attention.
o Eye contact: Immediately rinse with plenty of water for at least 15 minutes and seek medical help.
o Skin contact: Wash thoroughly with soap and water. If an allergic reaction occurs, seek medical attention immediately.
Pseudoboehmite is a functional material with excellent performance, but correct use is the key to ensure its effectiveness. During storage, operation, preparation and post-processing, it is necessary to strictly follow the specifications of moisture-proof, dust-proof, safety protection, etc. In addition, waste materials should be properly handled to avoid environmental pollution. Through scientific and reasonable use methods, pseudoboehmite can maximize its value in the fields of catalysis, adsorption, materials science, etc., while ensuring the safety and efficiency of experimental and production processes.
