Suggestion:
- The sealing effect is affected by the sealing temperature, and the higher the temperature, the better the effect.
- You can use diluted acetic acid to lower the pH value and use diluted ammonia to adjust the pH value to higher the pH value.
- Reducing the introduction of impurities and regular filtering can extend product life.
