How To Make Silica Gel Desiccant

1. Melt the raw material sodium silicate into liquid, filter and dilute it. 

2. Dilute concentrated sulfuric acid. 

3. Respectively, the use of air compressor will dilute sodium silicate liquid and sulfuric acid mixed into the reactor (about 4-6 meters from the ground), from the diameter of about 3 centimeters of rubber pipe to 45-60 degrees inclined above the spray.  Because of the tension of the air, the ball will form automatically.  

4. Aging in a certain concentration of dilute sulfuric acid liquid. 

5. Then in a certain concentration of dilute sulfuric acid liquid acid bubble. 

6. Use well water and treatment water for water washing. 

7.Into the drying room drying, drying is silica gel desiccant. 

8.According to the requirements of small packaging.
