Product Overview

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 pentahydrate 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 metasilicate pentahydrate should be handled and used with care, following proper safety precautions and guidelines.

Application

1. Widely used in various washing industries. In the washing industry, such as ultra-concentrated laundry powder, laundry detergent, laundry cream, dry cleaners, fiber whitening agents, fabric bleaching agents, etc., it is also widely used in metal surface cleaners, beer bottles, float solvent cleaners, and fully soluble After that, it can be used as metal rust inhibitor, scale cleaner, electrical device cleaner, and can be used in food industry detergents.

2. It can also be used as mud consistency adjuster and mud coagulant in crude oil and natural drilling and control mining projects.

3. In the construction industry, it is used as an accelerator for modulating acid-resistant mortar, acid-resistant concrete and cement.

4, in the paper industry can be used as a binder, waste paper peeling ink agent, paper surface treatment agent.

5. In textile industry, it can be used as printing and dyeing auxiliaries and fabric pre-treatment agent.

6, can also be used as soap fillers, detergents, egg fresheners, and molecular sieve vegetation, silicic acid and fireproof materials, etc.

Product Overview

Sodium Metasilicate Anhydrous is an inorganic substance, a stable chemical made of silicon, sodium and oxygen. This chemical is made with the melting of silica sand or quartz with sodium carbonate at high temperature to create glassy substances which are grind further into fine powder.

Sodium Metasilicate Anhydrous must be kept in dry, cool and well ventilated places as it can react with acids and oxidizing substances etc., to produce heat and fumes. Sodium Metasilicate Anhydrous is mostly used as a builder, surfactant and corrosion inhibitor in various industrial applications.

Sodium Metasilicate Anhydrous is used in a wide range of industrial chemicals such as detergent and in the cleaning industry as a cleaning agent and builder in laundry and dishwashing detergents. This chemical is also used in the construction industry to improve the strength and durability of cement and concrete compositions.

Sodium Metasilicate Anhydrous is also used as a dispersion and sizing agent in the paper and pulp industry which is very common. In the water treatment facilities, it serves as a corrosion inhibitor and a scale inhibitor. This chemical is used in the metal processing industry as a degreasing and cleaning Agent as well.

While handling Sodium Metasilicate Anhydrous, must wear protective gear including gloves, safety goggles, and a dust mask, it is advised to keep these things in mind. When this chemical is contacted with skin, eyes or any sensitive part of the human body, immediately flush it with water for at least 15 minutes and seek medical help right away at that time.
