Characteristics and Uses of Boric Acid
Sep. 12, 2020
The aqueous solution is weakly acidic, and boric acid is a stable crystal, which usually does not undergo chemical reactions when stored. When the temperature and humidity change drastically, it will recrystallize and agglomerate.
Boronic acid is 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 in glass, enamel, ceramics, metallurgy, electroplating, leather, dyes, paints, printing and dyeing, pesticides, fertilizers, textiles, electronic components and other industries. Used as analytical chemical reagents, buffers, wood preservatives, dye stabilizers, fabric fire retardants, insecticides, pH regulators, disinfectants, leather finishing agents, printing and dyeing auxiliaries, and agricultural production of fertilizers containing boron trace elements , It has fertilizer effect on many crops, can improve crop quality and increase yield.
Glass and fiberglass
It is used to produce high-grade glass and glass fiber such as optical glass, acid-resistant glass, organic boron glass, etc. It can improve the heat resistance and transparency of the glass, increase the mechanical strength, and shorten the melting time.
Enamel and ceramics
Boric acid is one of the components of glazes and pigments in the enamel and ceramic industries. It can reduce the thermal expansion of the glaze, lower the curing temperature of the glaze, thereby prevent cracking and deglazing, and improve the gloss and fastness of the product.
The borate added to the celluloid material can change its oxidation reaction and promote the formation of "carbonization". Therefore, it is flame retardant. Boric acid used alone or together with borax has a special effect on reducing the flammability of celluloid insulation materials, woodware, and cotton tires in mattresses.
Used as an additive and cosolvent in the production of boron steel, so that boron steel has high hardness and good rolling ductility. Boric acid can prevent surface oxidation of metal welding, brazing and sleeve welding. It is also the raw material of ferro-boron alloy.
Boric acid can be used as rust inhibitor, lubricant and thermal oxidation stabilizer. It is added to lubricants, brake fluids, metalworking fluids, water treatment agents and fuel additives.
Boric acid is one of the ingredients in the manufacture of corrugated paper adhesives, and also the peptizer for the manufacture of cool protein and dextrin adhesives. Boric acid greatly improves the wet glue strength by cross-linking the hydroxyl group.
Used in the production of various borates, such as sodium borohydride, ammonium hydrogen borate, cadmium borohydride, potassium borohydride, etc.
In the production process of nylon intermediates, phenylboronic acid cas no catalyzes the oxidation of hydrocarbons and generates esters to increase ethanol production, thereby preventing further oxidation of hydroxyl groups to generate ketones or hydroxy acids.
Storage and transportation characteristics
Store in a cool, dry, and well-ventilated warehouse. Do not store in the open, and avoid rain or moisture.
During transportation, ensure that the package is completely sealed to avoid rain or moisture.
