If the laboratory is splashed by strong alkali (NaOH or KOH), in addition to flushing with a large amount of water (H2O), a boric acid solution should also be applied. To neutralize the residual strong base. This is the most basic and one of the most recent uses. (If there is no boric acid solution around and being splashed by a strong base, carbonic acid can be used in an emergency, but boric acid is the first choice, because boric acid is also an acid, which is weaker than the carbonic acid in cola.) Prepare the buffer. Preparation of various borates. Insecticide for cockroaches and black beetles in carpets. Used in medicine as a hemostatic agent and preservative.
Used as pH regulator, disinfectant, antibacterial preservative, etc.; used to prepare borate, borate, optical glass, paint, pigment, boric acid soap, leather finishing agent, printing and dyeing auxiliary and medical disinfection Agent.
Used in capacitor manufacturing and electronic component industry, high-purity analytical reagents, medicinal disinfection and anti-corrosion, and preparation of chemical solutions for processing and processing of exposed photosensitive materials.
Used in glass, enamel, ceramics, medicine, metallurgy, leather, dyes, pesticides, fertilizers, textiles and other industries; used as chromatographic analysis reagents, and also used in the preparation of buffers; widely used in glass (optical glass, acid-resistant glass, In the industry of hot glass and glass fiber for insulating materials, it can improve the heat resistance and transparency of glass products, increase the mechanical strength, and shorten the melting time. In the enamel and ceramic industries, it is used to enhance the gloss and fastness of enamel products, and is also one of the components of glazes and pigments. Used as an additive and cosolvent in the metallurgical industry, especially boron steel has high hardness and good rolling ductility, and can replace nickel steel. Boric acid has antiseptic properties and can be used as a preservative, such as wood preservation. It is used in metal welding, leather, photography and other industries, as well as in the manufacture of dyes, heat-resistant and fire-resistant fabrics, artificial gems, capacitors, and cosmetics. It can also be used as insecticide and catalyst. Agricultural fertilizers containing boron trace elements are effective for many crops and can improve crop quality and yield.
Boric acid is also one of the basic raw materials for the production of other borides. The boron compounds produced by it are widely used in national defense and other industrial departments and scientific research units. ; Used as a pH regulator, antibacterial and antiseptic.
