Sodium Metasilicate Pentahydrate

Sodium metasilicate pentahydrate, white granules. Soluble in water and dilute lye; insoluble in alcohol and acid. The aqueous solution is alkaline. Easy to absorb moisture and deliquescence in exposed air. With detergent, emulsification, dispersion, wetting, permeability and pH buffering capacity.

Sodium metasilicate pentahydrate is a crystalline compound with the chemical formula Na2SiO3·5H2O. It is composed of sodium (Na), silicon (Si), oxygen (O), and water (H2O) molecules. The pentahydrate form indicates that it contains five molecules of water per molecule of sodium metasilicate.

Sodium metasilicate pentahydrate is a white, granular or powder-like substance with a high solubility in water. It has a basic pH and is alkaline in nature. It is commonly used in various industrial applications due to its unique properties.

One of the significant uses of sodium metasilicate pentahydrate is in cleaning products and detergents. It serves as a builder, helping to remove stains, grease, and dirt. It enhances the cleaning power of detergents by softening water and aiding in the dispersion of soils.

In addition to cleaning applications, sodium metasilicate pentahydrate is utilized in various industrial processes. It is employed as a corrosion inhibitor, especially in metal cleaning and surface treatment. It can help prevent rust and corrosion on metal surfaces.

Furthermore, sodium metasilicate  finds application in ceramics production, where it acts as a binder and helps improve the strength and integrity of ceramic materials.

It’s important to note that sodium  pentahydrate should be handled and used with care, following proper safety precautions and guidelines.

Application

1. Manufacturers widely use Sodium Metasilicate across various washing and cleaning industries. Cleaning applications include ultra-concentrated laundry powder, laundry detergents, laundry creams, dry-cleaning products, fiber whitening agents, and fabric bleaching agents. Manufacturers also use it in metal surface cleaners, beer-bottle cleaners, floatation solvent cleaners, and other fully water-soluble cleaning formulations. After dissolving it completely, users can apply Sodium Metasilicate as a metal rust inhibitor, scale remover, electrical equipment cleaner, and detergent in the food industry.
2. In crude oil extraction, natural gas drilling, and mining operations, Sodium Metasilicate can act as a mud consistency regulator and mud coagulant.
3. The construction industry uses Sodium Metasilicate as an accelerator when producing acid-resistant mortar, acid-resistant concrete, and cement.
4. The paper industry uses Sodium Metasilicate as a binder, a de-inking agent for waste paper, and a paper surface treatment agent.
5. The textile industry uses Sodium Metasilicate as a printing and dyeing auxiliary and as a fabric pretreatment agent.
6. Manufacturers also use Sodium Metasilicate as a soap filler, detergent ingredient, egg preservative, molecular-sieve material, silicic-acid source, and fire-resistant material.
