White Colorless Crystal Borax Powder Water Soluble For Enamel Cas 1303 96 4

Borax, white or colorless crystal, soluble in hot water, used in the manufacture of optical glass, medicine, soldering flux, reagents, enamel, etc

Borax is an inorganic compound with the chemical formula Na2 [B4O5 (OH) 4] · 8H2O, which can be abbreviated as Na2B4O7 · 10H2O. Molecular weight 381.372. It appears as white or colorless crystals or powder, with a slight sweet and salty taste. It is prone to losing its crystalline water in the air and weathering into white powder. Borax has a wide range of applications in industrial and agricultural production. For example, used as fillers and to enhance surface activity (cross-linking) in laundry detergent and soap; In glass, the transmittance of ultraviolet rays can be enhanced, and the transparency and heat resistance can also be improved; Adding it to enamel products can make the glaze firm and less likely to peel off, while increasing its luster. It is also widely used in fiberglass, welding non-ferrous metals, bonding jewelry, cosmetics anti-corrosion, pesticides, fertilizers, antifreeze agents, and medical disinfectants. Used as a herbicide in agriculture and for eliminating weeds in non cultivated areas.

Glass and enamel industry
In glass, it can enhance the transmittance of ultraviolet rays, improve the transparency and heat resistance of the glass. In enamel products, it can make the glaze less likely to peel off and give it a glossy appearance. It is also widely used in special optical glass, glass fiber, welding agents for non-ferrous metals, bonding agents for jewelry, printing and dyeing, washing (silk and woolen fabrics, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze agents, and medical disinfectants.

Industrial sector
Borax is also used as a solid lubricant in metal drawing industry. In the welding and maintenance of refrigeration equipment such as refrigerators, electric freezers, and air conditioners, it is often used as a (non active) flux to remove oxides from metal surfaces; Add a certain proportion of sodium chloride to borax. Compounds such as sodium fluoride and potassium chloride can be used as active fluxes for welding copper and steel pipes, as well as between steel pipes in refrigeration equipment.
