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.
