Borax, or sodium borate, a naturally occurring mineral compound is best known as a laundry booster and water softener but it has many industrial applications.
***Borax to prevent brown heart in turnips***
Borax is used to protect turnips against brown heart. it should be applied as a solution of 15g per litre of water and applied at a rate of 1 litre per 10 sq m.
***Borax in cosmetics***
Borax is used in cosmetics, toiletries and pharmaceuticals. It is also used as a crosslinking agent to emulsify waxes and
other paraffins used as a base for lotions, creams and ointments. How to prepare an emulsion: heat the oils in a double boiler. Dissolve the borax in hot water. Add the borax solution slowly to the hot oil, constantly stirring in one direction. Keep stirring until the creamy white emulsion has formed.
***Borax as a buffering agent***
Dissolved in water, Borax hydrolyzes to give a mildly alkaline solution and can be used to neutralise acids. It can be used in combination with strong alkilies to produce chemical compounds of lower pH. The relatively constant pH of Borax (approx pH 9.2) Dedahydrate solutions makes it an excellent buffering agent.
***Borax in adhesives***
Borax Decahydrate is part of the starch adhesive formulation for corrugated paper and paperboard, and is a peptising agent in the manufacture of casein-based and dextrin-based adhesives. It greatly improves the tack and green strength of the adhesive by crosslinking conjugated hydroxyl groups.
***Borax in metallurgy***
Borax Decahydrate has the ability to dissolve metal oxides and is exploited in the recovery of metals such as brass, copper, lead and zinc from scrap or smelting slag. In Iron metallurgy, Borax Decahydrate is used as a flux to prevent oxidation at the surface of the molten iron. In other metal working processes like welding, brazing, and soldering, Borax is used to cover the metal surfaces. This prevents any oxidation occuring by excuding air and moisture contact. It also can be used as a cleaning agent.
***Borax for corrosion prevention***
Borax finds many uses as a corrosion inhibitor in aqueous sytems as it can prevent oxidation of ferrous / Iron metals. Typical applications are in engine coolants, antifreezes and water treatments. Borax is highly soluble in MEG / ethylene glycol and can neutralise acids that are produced from the decomposition of the MEG prevention acidic corrosion of the metal surface.
***Other industrial uses for borax***
Borax is used: In the extraction of gold from metals. As a flame retardant and for putting out small fires without the risks of flare-up. A carrier for herbicides. As a stbiliser and bonding agent for specialist abrasives. As a neutraliser and carrier in the production of metal wire.
