Five, tank liquid maintenance and adjustment
1. Determination of alkali point: absorb 10ml of the tested solution into a 250ml conical bottle, add 50mL distilled water and 3 drops of phenolphthalein indicator, and titrate with 0.1mol/L sulfuric acid standard solution until colorless as the end point. Base point (Pt) =20CV V---- Volume of sulfuric acid standard solution, concentration of mL C--- sulfuric acid standard solution, mol/L 2. 3. In order to ensure normal operation, it is necessary to regularly analyze and control the free alkali solution and timely add defat powder. Adding 0.86 grams of defat powder per liter can increase the free alkali solution by one degree. 4. After oil saturation, oil removal effect decreases, or even complete failure, the whole tank should be replaced regularly.
Six, safety points and storage:
This product is alkaline, if contact skin, please immediately wash with water, preferably in a dry place, to prevent moisture absorption for a long time.
