What is sodium metasilicate anhydrous used for?

What is sodium metasilicate anhydrous used for?

Sodium metasilicate is used in fireproofing mixtures; in laundry, dairy, metal, and floor cleaning; in deinking paper; in washing carbonated drink bottles; in insecticides, fungicides, and antimicrobial compounds; as a chemical intermediate for silica gel catalysts; as an additive in soaps and synthetic detergents; as …

What is sodium metasilicate pentahydrate?

Sodium metasilicate is the ionic chemical compound with the formula Na2SiO3, and the main component of commercial sodium silicate solutions. It is colorless crystalline, deliquescent, and hygroscopic, soluble in water to give an alkaline solution.

What is the common name of sodium metasilicate?

waterglass
Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass.

What is disodium metasilicate used for?

This substance is used in the following products: washing & cleaning products, pH regulators and water treatment products, laboratory chemicals, adhesives and sealants, coating products, finger paints, non-metal-surface treatment products, polishes and waxes, polymers and cosmetics and personal care products.

What is difference between sodium silicate and sodium metasilicate?

The key difference between sodium silicate and sodium metasilicate is that sodium silicate refers to different ionic compounds which are silicate salts of sodium ions whereas sodium metasilicate is a type of sodium silicate having a sodium cation and SiO32- anion.

What is the pH of sodium metasilicate?

12.4 to 12.7
Spills of sodium metasilicate can be very slippery when wet. Sodium metasilicates are alkaline, meaning they have high pH. The pH typically ranges from 12.4 to 12.7.

What is the meaning of sodium silicate?

: any of various water-soluble substances obtained in the form of crystals, glasses, powders, or aqueous solutions usually by melting silica with a sodium compound (such as sodium carbonate or sodium hydroxide): such as.

Is sodium silicate safe?

Sodium Metasilicate is a GRAS (generally regarded as safe) food ingredient. Aqueous solutions of Sodium Silicate species are a part of a chemical continuum of silicates based on an equilibrium of alkali, water, and silica.

Does sodium metasilicate dissolve in water?

Water
Sodium metasilicate/Soluble in

What is the side effects of sodium silicate?

Ingesting sodium silicate is unlikely; however, if ingested, it is moderately toxic and may cause pain and burns of the esophagus and gastrointestinal tract with vomiting, nausea, and diarrhea. There are no known chronic hazards associated with sodium silicates.

How does sodium metasilicate dissolve in water?

Bring purified water to a low simmer (approximately 175 degrees) on an electric stove. Stir sodium silicate powder into hot water with a long-handled metal spoon. Continue stirring until the powder is completely dissolved. Remove solution from heat and allow it to cool to room temperature.

Why is sodium silicate used in detergent?

Detergents are used in cleaning household surfaces, dishes and washing laundry. Sodium silicate is a building agent used in many commercial detergents. The purpose of the sodium silicate to is prevent mineral deposits on surfaces after washing by removing water hardness.

Which is the best sodium metasilicate anhydrous product?

Sodium metasilicate anhydrous is a multifunctional product that shows excellent pH-regulating capacity, efficient detergency, effective corrosion inhibition, good dispersing and bleach stabilizing properties and which is environmentally safe.

How is sodium metasilicate made in a dryer?

Sodium metasilicate is made by adding caustic soda to liquid sodium silicate to obtain an equal molar ratio of sodium oxide (Na2O) to silicon dioxide (SiO2). The resulting metasilicate liquor is then cooled to crystallize the pentahydrate product or passed through a dryer to remove water and yield the anhydrous product.

What is the molar ratio of metasilicate anhydrous?

Metasilicate anhydrous contains both silica and alkalinity in a molar ratio of 1:1 between silica and sodium oxide. The silica part gives sodium metasilicate corrosion inhibiting properties that help to protect both metal and non-metal surfaces.

How much sodium metasilicate is produced per year?

Sodium metasilicate is produced by the fusion of sodium carbonate with silicon dioxide or silica sand at about 1400 °C. It is commercially available in various grades and in both the anhydrous and pentahydrate forms from several U.S. companies. Annual capacities range from 50 to 806 million pounds.
