Boric acid is an inorganic compound with the chemical formula H3BO3. It is a white crystalline powder with a smooth feel and no smell. It is widely used in the glass industry. It can improve the heat resistance and transparency of glass products, increase mechanical strength, and shorten melting time. It can also be used as antiseptic and disinfectant.
1. Used to produce high-grade glass and glass fibers such as optical glass, acid-resistant glass, organic boron glass, etc. It can improve the heat resistance and transparency of glass, increase mechanical strength, and shorten melting time.
It can reduce viscosity, control thermal expansion, prevent devitrification, improve chemical stability, and improve resistance to mechanical and thermal shock.
2. Used in the enamel and ceramic industries to produce glazes, it can reduce the thermal expansion of the glaze and lower the curing temperature of the glaze, thereby preventing cracks and deglazing and improving the gloss and fastness of the product.
3. Used to produce boric acid ointment, disinfectants, astringents, antiseptics and other flame retardants
4. Used as additives and cosolvents in the production of boron steel to make boron steel have high hardness and good rolling properties. Boric acid can prevent surface oxidation of metal welding, brazing and sleeve welding.
5. In the leather industry, it is used to degrease the surface of bare leather to prevent gray spots on the surface of the leather after re-tanning.
6. Boric acid can be used as a rust inhibitor, lubricant and thermal oxidation stabilizer. It is added to lubricants, brake fluids, metalworking fluids, water treatments and fuel additives.
7. It is one of the ingredients for making corrugated paper adhesives, and it is also a peptizer for making cool protein and dextrin adhesives. Boric acid greatly improves wet glue strength by cross-linking hydroxyl groups.
8. Used to produce various borates, such as sodium borohydride, ammonium hydrogen borate, cadmium borotungstate, potassium borohydride, etc.
9. In the production process of nylon intermediates, boric acid catalyzes the oxidation of hydrocarbons and generates esters to increase the yield of ethanol, thus preventing further oxidation of hydroxyl groups to generate ketones or hydroxy acids.
10. The chemical fertilizer industry is used to produce candle wicks and boron-containing fertilizers.
11. Used as analytical chemical reagents for preparing buffers and various culture media for haploid breeding.
