Borax product introduction
Borax is also called coarse borax . In terms of chemical composition, it is sodium tetraborate containing 10 water molecules. Its crystals are plate-shaped or column-shaped, and the crystals are gathered together to form clusters, granular, porous soil blocks, etc., and the color is white with gray or yellow, blue, green, etc., with a glassy luster.
Physical and chemical properties:
Colorless translucent crystal or white crystalline powder. Odorless and salty. The specific gravity is 1.73. All crystal water is lost at 320°C. Easily soluble in water and glycerin, slightly soluble in alcohol. The aqueous solution is weakly alkaline. Borax can be slowly weathered in the air. When melted, it becomes a colorless glass-like substance. Borax has a bactericidal effect and is harmful to humans when taken orally.
use:
Mainly used in glass and enamel industries. In glass, it can enhance the transmittance of ultraviolet rays, improve the transparency and heat resistance of glass. In enamel products, it can make the enamel not easy to fall off and make it shiny. In special optical glass, glass fiber, non-ferrous metal welding agent, jewelry binder, printing and dyeing, washing (silk and woolen fabrics, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and medicine It also has a wide range of applications such as using disinfectants. Borax is the basic raw material for preparing boron-containing compounds. Almost all boron-containing compounds can be prepared from borax. They have important and wide-ranging applications in sectors such as metallurgy, steel, machinery, military industry, knives, papermaking, electronic tubes, chemicals and textiles.

Mainly used in glass and enamel industry. In glass, it can enhance the transmittance of ultraviolet ray, improve the transparency and heat resistance of glass. In enamel products, it can make the glaze not easy to fall off and make it have luster. It is also widely used in special optical glass, borax glass fiber, non-ferrous metal welding agent, jewelry binder, printing and dyeing, washing (silk and wool), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and medical disinfectants. Borax is the basic raw material for the preparation of boron containing compounds. Almost all borides can be prepared by borax. They are widely used in metallurgy, iron and steel, machinery, military industry, cutting tools, paper making, electronic tube, chemical industry and textile. In human medicine, borax is used in the treatment of skin and mucous membrane disinfection and antisepsis, tinea pedis, pulpitis, mycotic vaginitis, cervical erosion, bedsore, acne, eczema of external auditory canal, herpes virus skin disease and epilepsy. In recent years, borax is also used in the treatment of tumor. In animal medicine, borax is used in the treatment of chicken laryngotracheitis, goat infectious pustulosis, swine mycoplasma pneumonia and bovine chronic mucinous endometritis. As a feed additive, borax has also attracted people's attention.
