Borax is a mineral compound and one of the most important boric and salt. Borax Decahydrate, with the chemical formula Na2B4O7.10H20, is a purified form of natural sodium borate.
Combined with boric oxide (B2O3), sodium oxide and water, it is a weak alkaline salt, white and crystalline and has excellent buffering and flux properties. The appearance of this material in powder or granule form is an important multipurpose source of B2O3. , Especially for a process where the simultaneous presence of sodium is important.
Borax Decahydrate Physical and Chemical properties
In the table below some of the chemical and physical properties of this product are mentioned. all data that is mentioned in this table is gathered from Wikipedia website:
Borax has been used in many cleaning products as a pH buffering agent, to aid oil emulsions and as a mild abrasive.
Use this material to remove medium to heavy soils that they face in industrial operations and add it to powdered hand soaps.
This compound is very effective for cleaning surfaces and is added to formulations to clean hard surfaces such as metals, glass, and ceramics.
Other uses of this material include the following:
Detergents and cosmetics
- used as an additive in hand cleaners, polishes, and waxes
- Removes oily soil from fabrics
- industrial/institutional cleaning compounds
- pH buffering
- softening of the wash water
- stabilize enzymes
- Boric acid is used as a cleanser and mild buffer in contact lens solutions
- cross-linking agent to emulsify waxes and other paraffin that form the base for lotions, creams, and ointments
- cosmetics, toiletries, and pharmaceuticals
In addition to its application in the detergent and Sanitary
industries due to its ability to dissolve metal oxides, it is used in the recovery of metals such as rice, copper, lead and zinc from scrap or smelting.
In ferrous metallurgy, borax is used to prevent oxidation at the molten ingot surface as a coating flux.
Other uses of this material in welding, sheeting, and soldering are used to coat metal surfaces.
It slows corrosion in aqueous systems, water treatment chemicals, and in the manufacture of automotive and engine coolant formulations
In railroad and other diesel engine coolants, aqueous solutions of borax decahydrate have replaced chromates.
Due to its high solubility in ethyl glycol, it is widely used in antifreeze production.
It neutralizes the acid residue caused by ethylene glycol decomposition and minimizes oxidation at the metal surface.
This product is used as a stabilizing agent in the manufacture of refractory materials and forms an intermediate -temperature glass bond before forming a ceramic bond.
It is also used in starch adhesive formulations for the production of corrugated paper and cardboard.
As a crosslinking agent of conjugated hydroxyl groups, it improves the performance of these adhesives based on casein and dextrin based adhesives.
