Borax, type A

Production of special-purpose glass, glass fibre and glass fibre cloth.      

Borax is a source of boric oxide that is used in the process of glass manufacturing, including special-purpose borosilicate glass, insulating and textile glass fibre. Boric oxide has an impact on the final product characteristics by acting simultaneously as a flux material and as a bonding agent. Besides that borax is a source of sodium. When the “borax-sodium” ratio needs to be regulated, borax is usually used combined with boric acid.   

In the technological process of special-purpose glass manufacturing borax promotes melting of charging materials, reduces the viscosity of melted materials and prevents devitrification resulting in final product’s gain in strength and it's resistance to mechanical, chemical and thermal impacts.    

In the process of glass fibre and glass fibre cloth manufacturing borax promotes fiberization which leads to glass fibre hardening and improvement of its chemical stability as well as heat and sound isolation characteristics.  

Lacquer coating and enamel manufacturing

In the process of lacquer coating and enamel manufacturing borax is used as a source of boric oxide. Being a part of lacquer coating and enamel, borax acts as an inorganic binder.

Addition of boric oxide decreases product’s melting temperature and prevents the formation of cracks. Boric oxide content control in the manufacturing process allows achieving consistent parameters of thermal expansion of lacquer coating and of material that lacquer is covering which ensures final product’s mechanical reliability, wearing property, water impermeability and its resistance to the corrosive environment.

Metallurgical industry

Borax and boric acid are used as a source of boric oxide which serves as an antioxidant. A mixture of borax and boric acid is widely used as a fluxing agent.

To prevent oxidation of metal surfaces in the process of hot treatment, for example in the process of tube brazing, protective fluxing agents based on borates are used.

At high temperatures boric oxide dissolve oxides (for example calcium or ferrum oxides).

Application of borates improves physical and chemical characteristics of composite metals and steel.

Goldmining

Non-aqueous borax is widely used in the process of gold ore processing.

In the process of gold ore processing borax decreases the viscosity of melted materials, dissolves additives and prevents oxidation.

Main effects from the application of non-aqueous borax is an increase of gold yield and the improvement of gold‘s quality.

Cooling liquids, oil lubricants and hydraulic fluids manufacturing

Borax is widely used in the process of cooling liquids, oil lubricants and hydraulic fluids manufacturing due to the fact that on the metal surface borax and ferrum form a complex compound which acts as a corrosion protection barrier. Moreover, if borax is present, organic compounds which can appear at high temperatures in the process of degradation are neutralized.

It is preferable to apply orax instead of silicon compounds because it doesn’t form jells and adsorbs water, preventing clogging and occurring of gas bubbles in the system.

Borates application improve lubricating efficiency, thermal performance and other characteristics of the final product.

Green fibre, glue and chipboard manufacturing. For construction.

In the process of green fibre, glue and chipboard manufacturing as well as in the process of woodcutting, borates are used as fire-retarding agents and antiseptic.

Glue made of casein and dextrin with a presence of borates has better product’s characteristics: improved product’s viscosity, resistance to low temperatures, fluidity and so on.

Borates improve green fibre’s heat and sound isolation characteristics.

In the process of construction, borax is used as a corrosion inhibitor for metal structures.

Detergent, cleaning and bleaching agents manufacturing     

Borax is a primary component of the sodium perborate production process which is the main oxygen-containing bleaching agent for powdery detergents.

Borax is included as a component of numerous industrial-grade or household cleaning agents and polishes in order to improve their cleansing properties, to maintain the adequate pH level and viscosity of preparation as well as to increase its capacity to form emulsions.
