Sodium tetraborate decahydrate | Borax

Product Description

Sodium tetraborate decahydrate.Borax Decahydrate is the refined form of natural sodium borate. Composed of boric oxide (B2O3), sodium oxide, and water, it is a mild, alkaline salt, white and crystalline, with excellent buffering and fluxing properties. Available in powder or granular form, Borax Decahydrate is an important multifunctional source of B2O3, particularly for processes in which the simultaneous presence of sodium is beneficial.

Application

The role of borax in concrete mainly includes:

Retarding effect: Borax can be used as a retarding agent for concrete, by forming a calcium borate coating on the surface of cement clinker particles, delaying the coagulation of sulphoaluminate cement and maintaining its fluidity. In the production of aerated concrete, the main function of borax is to delay the hydration and setting rate of cement in the mixture and regulate the thickening rate of the mixture.

Improve the strength and durability of cement: Boron can promote the setting and hardening process of cement, improving the strength and durability of cement. Boron can form a stable complex in cement, making it easier for the Silicate ions in cement to combine with water molecules, thus promoting the solidification and hardening process of cement.

Improve the durability of cement: Boron can regulate the microstructure in cement and improve the durability of cement. The addition of boron can change the crystal structure in the cement molecules, making it more stable, thus improving the durability and stability of the cement.

Improve the special functions of cement: Boron can improve the special functions of cement, such as radioactive protection and thermal stability. The addition of boron in cement can make the cement have the function of radiation protection, and improve the high-temperature resistance of cement so that the cement still has stable properties in high-temperature environments.

Glass and glass fiber

In the manufacture of insulating glass wool, textile fiberglass, and borosilicate glass (heat-resistant glass, electric light source glass, glass burner, drugs, cosmetics bottles, hollow beads, optical lenses, sealed glass) and other areas, as provided by oxidation boron materials.

Ceramic and enamel glazes

borax increases ceramics’ (such as tiles, tableware, ceramics, and enamel devices, etc.) compressive strength, abrasion resistance, and chemical resistance.  As the thermal expansion coefficient of B2O3 on the control of making the glaze to adapt the line to improve, but also can reduce the melting temperature of B2O3, prevent loss through.  Makes the product more smooth and more perfect.

Other applications:

Fertilizer, detergent, bleach detergent, flame retardant, antirust, binder, stabilizer, emulsifier, etc.
