In enamel products, it can make enamel not easy to fall off and shiny. It is also widely used in special optical glass, glass fiber, non-ferrous metal welding agent, jewelry adhesive, printing and dyeing, washing (silk and woolen goods) and so on. ), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and medical disinfectants.
In industry, borax is the most important industrial boron mine. 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 for metal wire drawing in industry. In the welding and maintenance of refrigeration equipment such as refrigerators, freezers and air conditioners, it is usually used as (inert) flux to purify metal surfaces. Removing the oxide on the metal surface; Add a certain proportion of sodium chloride to borax. Sodium fluoride, potassium chloride and other compounds can be used as active fluxes to weld copper pipes and steel pipes, steel pipes and steel pipes in refrigeration equipment.
Extended data
1. bacteriostasis. It is reported that borax is a kind of weak alkali, which has weak antibacterial effect like boric acid. Using plate method to make the culture medium contain 10% borax, which can inhibit Escherichia coli, Pseudomonas aeruginosa, Bacillus anthracis, Bacillus dysenteriae, Bacillus typhi, Bacillus paratyphi, Proteus, Staphylococcus and Candida albicans. It is proved by paper method that borax also has inhibitory effect on diphtheria, Brucella bovis, pneumococcus, meningococcus and hemolytic streptococcus.
2. Anticonvulsive and antiepileptic effects. The results showed that borax had anticonvulsant effect on mice in the range of 130 mg/kg to 260 mg/kg, and it could be gradually enhanced with the increase of administration times, and the maximum anticonvulsant effect appeared around 1 week after administration. Injection can accelerate anticonvulsant effect. Intraperitoneal injection of 260mg/kg can antagonize electroconvulsive, and the antagonistic rate is 100%. Borax combined with other antiepileptic drugs can quickly control grand mal and status quo.
3. Other functions. Borax also has antiseptic and protective effects on skin and mucosa. This product can be used to wash ulcers and abscesses in clinic, especially mucosal inflammation, such as conjunctivitis and gastritis, which can cause scales on the mucosa. Oral use for urethral sterilization, especially when urine is acidic, will make it alkaline.
