Whether it is a laboratory or a business unit, the following principles should be followed when storing rare earth products.
, the principle of sealing. Most rare earth products are sealed and preserved, which is an important principle of product preservation. It mainly includes products with the following properties: products that are easy to deliquescent, reagents that are easy to interact with water vapor, and reagents that are easy to be oxidized or reduced.
, the principle of avoiding light. For rare earth products that are easy to decompose when exposed to light or heat, avoid sunlight and store them in a cool place.
, the principle of isolation. Rare earth products should be kept away from the fire source, and strong oxidants should be separated from substances that are easy to be oxidized.
, the principle of ventilation. The preservation of most rare earth products should follow this principle, especially strong oxidizing agents.
, the principle of low temperature. If the temperature is too high, it is easy to decompose the product, especially in the hot weather in summer, and if necessary, it can be cooled down, such as turning on the air conditioner, blowing the fan, etc.
