Product Description

Product Description

 

Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. Agriculture use borax decahydrate is usually a white powder consisting of soft colorless crystals that dissolve easily in water.

Sodium Borate has been mainly used in the manufacturing high quality glass, optical glass, glaze of pottery and porcelain, glaze of enamel, detergent, bleaching agent, cleaning agents, flame retardant, rust inhibitor and caking agent. It could be also used as the carrier of the lubricant used in metal wiredrawing, the stabilizer of refractory material and skeleton former, the coated fluxing agent in metallurgy, the retarder of cement and concrete, the buffer of pH value in water system and emulsifier of paraffin.

Product Application

(1) Borax can be used as jewely adhesive, printing and dyeing, washing (silk, wool, etc.), gold refimning, cosmetics, pesticides, fertilizers, boraxsoap,medical preservatives,antifreeze. disinfectants. etc.
(2) In the metallurgical industry, borax is used for calcination, welding and metal testing, and is also a good fux: When welding metal. borax is
used to purify the surface of the metal
(3) Raw materials for ceramic glazes and glass. In the glass, the transmission rate of ulraviolet light can be improved, and the transparency andheat resistance of the glass can be improved. In enamel products, it can make the enamel not easy to fall off and make it shiny; Also widelyused in special optical glass, glass fiber.
(4) Borax is the basic ray matemal for the produchion of boron-contaming compounds, and almost al boron compounds can be made from
borax.
