Stability analysis of Ultrafine sodium sulfate powder (Yuanming powder) under different temperature and humidity conditions
Publish Time: 2024-07-01
Ultrafine sodium sulfate powder (Yuanming powder), also known as Yuanming powder, is a white, odorless, bitter crystal or powder. Due to its high purity and fine particles, it has a wide range of applications in many fields. However, under different temperature and humidity conditions, the stability of Ultrafine sodium sulfate powder (Yuanming powder) will be affected to a certain extent.
First of all, from the perspective of temperature, the solubility of sodium sulfate varies greatly with temperature. When the temperature is less than 40°C, the solubility of sodium sulfate increases with increasing temperature. Specifically, the solubility of sodium sulfate is 19.5g at 20°C, while at 30°C and 40°C, its solubility reaches 40.8g and 48.8g respectively. However, when the temperature exceeds 40°C, as the temperature further increases, the solubility of sodium sulfate will decrease instead. For example, at 50°C, its solubility is 46.2g. This property shows that Ultrafine sodium sulfate powder (Yuanming powder) can remain stable in a lower temperature range; but under high temperature conditions, especially when it exceeds 40°C, special attention should be paid to changes in its solubility and stability.
Secondly, humidity is also an important factor affecting the stability of Ultrafine sodium sulfate powder (Yuanming powder). Sodium sulfate is easily absorbed by water when exposed to air to form sodium sulfate decahydrate, also known as mirabilite. This change not only affects the purity of the product, but may also affect its performance in certain applications. Therefore, during storage and transportation, humidity needs to be strictly controlled to prevent Ultrafine sodium sulfate powder (Yuanming powder) from absorbing water and agglomerating or deteriorating.
In summary, the stability of Ultrafine sodium sulfate powder (Yuanming powder) under different temperature and humidity conditions is affected to a certain extent. During storage and use, corresponding measures need to be taken according to specific conditions to ensure the quality and stability of the product. For example, in a high temperature environment, the stability of the product can be maintained by lowering the storage temperature or taking ventilation and heat dissipation measures; in a high humidity environment, it is necessary to reduce the impact of humidity on the product by sealing the package or adding a desiccant.
