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

The professional name of soda ash is hydrogen Sodium oxide has its applications in papermaking, synthetic detergents and soaps, viscose fiber, rayon and cotton fabrics and other light textile industries. However, depending on the process, some need to use liquid caustic soda, but due to cost and transportation issues, it is necessary to purchase caustic soda flakes and dissolve them into liquid caustic soda for use. But do you know the relevant precautions during the dissolution process?

1. Pour Caline Soda into water Riga, stir while adding, avoid 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, it will cause agglomeration and the dissolution will become very slow;

2. There is no need to lower the temperature when dissolving. Wait until the first dissolution is completed and then lower the temperature. This results in a more concentrated lye.

3. The higher the temperatureCaline alkali The higher the solubility, the higher the concentration of the alkali solution obtained, but be careful not to add too much caustic soda, because once the solubility of the solution is saturated, adding more caustic soda will not be dissolved, and it will agglomerate and affect the effect.

4. During the dissolution of caustic soda in water, if If the amount is large, there is a possibility of splashing, but a small amount of caustic soda will not splash out when dissolved. When dissolving caustic soda, it is necessary to add alkali to the water, and pay attention to protection. Take protective measures yourself and perform this water-reactive operation without harming personal safety.

5. If a fixed capacity is required, use less water and wait for it to dissolve After that, cool it down and dilute it with water.

When dissolving caustic soda in water, follow the above steps to avoid local overheating and speed up dissolution speed.
