Sodium Silicate Production Plants

Ballestra has established itself as a leader in the design and supply of sodium silicate plants, leveraging decades of experience in building facilities of varying capacities and using diverse silica sands worldwide.
This expertise ensures the production of high-quality, transparent, and solid-free sodium silicate solutions, with proven operational reliability over the years.

The Role of Sodium Silicate in Detergent Formulations

Sodium silicate is a critical component in synthetic detergent powders, offering multiple functional benefits:

  • Soil Suspension: Prevents soil from redepositing on fabrics.
  • Water Softening: Forms precipitates easily rinsed away during washing.
  • Wetting and Emulsifying Properties: Especially effective on glass and glazed surfaces, making it a key ingredient in dishwashing detergent formulations.
In detergent powder formulations, sodium silicate can constitute up to 10% of the formula and is typically used as an aqueous solution with varying dry-matter content.

Applications Beyond Detergents
The versatility of sodium silicate extends well beyond detergents, finding applications in industries such as:

  • Concrete Production: Enhances durability and chemical resistance.
  • Adhesives and Coatings: Provides strong bonding and protective properties.
  • Gels and Films: Used in specialized industrial and consumer applications.
  • Paper Industry: Acts as a deflocculating agent.

Process Features of Sodium Silicate Production

The production process involves precision dosing, efficient heat recovery, and optimized reactor design:

  • Preparation:
    Silica sand, caustic soda solution, and process water are dosed into a preparation vessel.
    Preheating of process water is achieved by recovering heat from the hot sodium silicate produced in the previous batch, ensuring energy efficiency.
  • Reaction:
    The preheated solution is transferred to the reactor, where the suspension is heated to the desired reaction temperature.
    The reaction occurs at controlled temperature and pressure, ensuring complete conversion of reagents.
  • Filtration:
    Once the reaction is complete, the reactor is depressurized, and the raw sodium silicate solution undergoes filtration.
    When the filtration pressure reaches its maximum allowable limit, the filter press is opened and cleaned.
