How to make calcium grease?
Calcium Grease Formulation and Manufacturing Process
Composition
Tallow (Animal Fat): 13 kg
Rice Fatty Acid: 7 kg
Hydrated Lime (Calcium Hydroxide): 3 kg
Caustic Soda (Sodium Hydroxide): 150 g
Latex Rubber Milk: 150 g
Base Oil: 80 kg
Process
1. Preparation
Safety First: Ensure all personnel are wearing appropriate PPE (gloves, goggles, and lab coats).
Equipment Check: Verify that all equipment (reaction vessel, heating system, and mixers) is clean and operational.
2. Initial Charging
Heating and Stirring: Begin heating the mixture while continuously stirring until the materials are completely melted and uniformly mixed.
3. Addition of Hydrated Lime
Mixing: Slowly add 3 kg of hydrated lime to the melted mixture.
Continued Heating: Ensure the lime is thoroughly mixed into the blend.
4. Water Addition
Hydration: Once the lime is fully incorporated, add 150 ml of water to the reaction vessel.
Temperature Monitoring: Gradually increase the temperature to 70°C.
5. Caustic Soda Solution
Preparation of Solution: Dissolve 150 g of caustic soda in 450 ml of water to create a caustic soda solution.
Addition: Slowly add the caustic soda solution to the reaction vessel.
Temperature Increase: Raise the temperature to 110°C and maintain it for 1 hour to ensure complete saponification.
6. Final Additions and Mixing
Base Oil: Add the remaining 79 kg of base oil to the saponified mixture.
Latex Rubber Milk: Introduce 150 g of latex rubber milk into the blend.
Thorough Mixing: Continue mixing the entire batch to ensure a homogeneous product.
7. Cooling and Homogenizing
Controlled Cooling: Gradually reduce the temperature while maintaining stirring to achieve a uniform consistency.
Final Checks: Ensure the mixture has thickened properly and has the desired grease properties.
8. Quality Control
Testing: Perform standard quality control tests (e.g., penetration, drop point, and mechanical stability) to verify that the grease meets the required specifications.
Adjustments: Make any necessary adjustments to the formulation if the grease properties do not meet the desired standards.
9. Packaging
Transfer: Once the grease has achieved the correct consistency and passed quality control tests, transfer it into appropriate containers for storage and distribution.
Safety Considerations
Ventilation: Ensure proper ventilation in the production area to avoid inhalation of fumes.
Handling Chemicals: Handle all chemicals with care and follow safety guidelines to prevent accidents
