How does caustic soda dissolve into liquid caustic soda? What are the precautions?

The professional name of caustic soda is sodium hydroxide, and it is used in light textile industries such as papermaking, synthetic detergent and soap, viscose fiber, rayon and cotton fabrics. However, according to the difference in the process, some need to use liquid caustic soda, but also need to consider the cost and transportation issues, so it is necessary to buy caustic soda and dissolve it into liquid caustic soda for use, but do you know the relevant precautions during the dissolving process?

1. Add the caustic soda to the water and stir while adding to avoid partial overheating until it is completely dissolved: because the caustic soda should not be left in the water for too long or poured into the water all at once will cause agglomeration and the dissolution will become very slow;

2. There is no need to lower the temperature when dissolving, and then lower the temperature after the first dissolution is completed, so that a higher concentration of lye can be obtained.

3. The higher the temperature, the higher the solubility of the caustic soda, and the higher the concentration of the obtained lye, but be careful not to add too much caustic soda, because once the solubility of the solution is saturated, it will not be dissolved if you put caustic soda again. It will agglomerate and affect the effect.

4. If a large amount of caustic soda is added in the process of dissolving caustic soda in water, there may be splashing, but a small amount of caustic soda will not splash out when dissolving caustic soda. It is necessary to add caustic soda In the water, you must also pay attention to protecting yourself, take protective measures, and perform this operation that reacts with water on the premise of not harming personal safety.

5. If you need a fixed capacity, use a little less water. After the dissolution is complete, let it cool down, and then use water to fix the volume.
