In enamel products, it can make the enamel not easy to fall off and make it shiny. It is also widely used in special optical glass, glass fiber, welding agent for nonferrous metals, adhesive for jewelry, printing and dyeing, washing (silk and woolen goods, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and medical disinfectants.
In industry, borax is the most important industrial boron mineral. Borax is the most important compound of boron. Boron is often listed as a rare element abroad, but there are abundant borax minerals in China. Therefore, boron is not a rare element in China, but a high-yield element. Borax is also used as a solid lubricant in metal wire drawing and other aspects in industry. It is often used as an (inactive) flux to purify metal surfaces in welding and maintenance of refrigeration equipment such as refrigerators, freezers and air conditioners. Removing oxides on the metal surface; Add a certain proportion of sodium chloride to borax. Compounds such as sodium fluoride and potassium chloride can be used as active flux to weld copper pipes and steel pipes and steel pipes and steel pipes in refrigeration equipment.
Extended data
1. Bacteriostasis. It has been reported that borax is a weak base, which has the same weak antibacterial effect as boric acid. Borax containing 10% in the culture medium by plate method can inhibit Escherichia coli, Pseudomonas aeruginosa, Bacillus anthracis, Shigella flexneri, Salmonella typhi, Bacillus paratyphi, Proteus, Staphylococcus and Candida albicans. It is proved by paper method that borax can also inhibit diphtheria, Brucella bovis, pneumococcus, meningococcus and hemolytic streptococcus.
2. Anticonvulsive and antiepileptic effects. Experiments show that borax has anticonvulsant effect when given to mice 1 30 mg/kg ~ 260 mg/kg, which can be gradually enhanced with the increase of administration times, and the maximum anticonvulsant effect occurs around1week after administration. Injection can accelerate the anticonvulsant effect. Intraperitoneal injection of 260mg/kg can antagonize electric convulsion, and its antagonism rate is 100%. Combined with other antiepileptic drugs, borax can quickly control grand mal and status epilepticus.
3. Other functions. Borax also has the function of antisepsis and protection of skin mucosa. This product can be used to wash ulcers and abscesses in clinic, especially mucosal inflammation, such as conjunctivitis and gastritis, which can make the mucosa scale. Oral use for urethral sterilization, especially when urine is acidic, can make it alkaline.
