There are still many taboos about the use of glass-lined reactors. So under what circumstances is it not suitable to use glass-lined reactors? This is the relevant question we are going to talk about in this issue. The answer to this question is in the following explanation. :

1. Water: If the operating temperature is greater than 150¡ãC, water corrosion will occur in the glass-lined reactor;

2. Ammonia: When the operating temperature is greater than 155¡ãC and the pH is greater than 12, the glass lined equipment cannot be used;

3. Phosphoric acid: with a concentration of 98% and a temperature of 100¡ãC, the annual corrosion rate is greater than 1.25mm, so avoid using it;

4. Hydrochloric acid: It cannot be used when the reaction temperature is greater than 180¡ãC and the concentration is less than 10%;

5. Sulfuric acid: Avoid using this equipment when the reaction temperature is greater than 175¡ãC and the concentration is less than 20%;

6. Sodium hydroxide and potassium hydroxide: If used at a temperature greater than 110¡ãC and a pH greater than 12, it will cause damage to the glass lined equipment;

7. Sodium hydroxide: concentration 4%, temperature 75¡ãC, annual corrosion rate greater than 1.25mm, cannot be used.

That's the main content of this issue. I hope everyone can pay attention to the above items or usage glass-lined requirements in time.
