1, Mainly used in glass and enamel industries. In glass, it can enhance the transmittance of ultraviolet ray and improve the transparency and heat resistance of the glass.
In enamel products, can make the enamel not easy to fall off and make its luster.
In special optical glass, glass fiber, welding agent for nonferrous metals, jewelry of adhesive, printing and dyeing, washing (silk and wool, etc.), gold refined soap, cosmetics, pesticide, fertilizer, borax, preservatives, antifreeze, etc, also have a wide range of applications.
2, Borax is the basic raw material for the preparation of boron-containing compounds. Almost all of the boron-containing compounds can be obtained by borax. They have important and extensive uses in the metallurgy, steel, machinery, military, cutting tools, paper, electronic tubes, chemical and textile sectors.
3, Used for herbicides, used for non-farming area devitalizing weeding, except for use alone, mixed with sodium chlorate to reduce the flammability of sodium chlorate.
5, In industry, borax is the most important industrial boron mineral. Borax is the most important boron compound. Boron is often listed as a rare element in foreign countries. However, boron is abundant in our country. Therefore, boron is not a rare element in our country, but rather an element of high yield. Borax in the industry is also used as a solid lubricant for metal wire drawing. It is often used as (non-active) flux for cleaning metal surfaces in the welding and maintenance of refrigeration equipment such as refrigerators, electric freezers, and air conditioners. Remove oxides from metal surfaces; add a certain percentage of sodium chloride to borax. Compounds such as sodium fluoride and potassium chloride can be used as active fluxes for the welding of copper tubes and steel tubes and between steel tubes and steel tubes in refrigeration equipment.
