Boric acid
Product introduction
Boric acid is a kind of inorganic compounds, chemical formula of H3BO3, white crystalline powder, with creamy feel, no smell, a large number of used in glass industry, can improve the heat-resistant, transparent glass products performance, improve the mechanical strength, shorten the melting time, also can be used as antiseptic, disinfectant.
Method of storage: should be stored in a dry, clean inside storeroom, shall not open piled up, should avoid to rain or moisture. Should be installed in a covered wagon, or belt in the car cabin transportation, should not mix with damp items and non-ferrous materials piled up, the means of transport must be dry clean.
Application field
Glass and glass fiber, used in the production of optical glass, acid, organic boron glass and other advanced glass and glass fiber, glass can improve the heat resistance and transparency, improve the mechanical strength, shorten the melting time.
B2O3 in the manufacture of glass and glass fiber plays a flux and network formation of dual role. In glass fiber production, for example, we can reduce the melting temperature to help drawing. In general, B2O3 can reduce viscosity, control of thermal expansion, prevent devitrification, improve the chemical stability, improve the mechanical shock and thermal shock resistance.
In the lower glass production requirement of sodium borate often with sodium borate (such as five water borax or anhydrous borax) using a mixture of sodium boron than to adjust the glass. This is very important for boron silicate glass, because of the high boron oxide in low sodium aluminum cases show the good solubility.
Enamel and ceramic, enamel, ceramic industry for the production of glaze, can reduce the thermal expansion of the glaze and reduce the curing temperature of the glaze, so as to prevent crack and glaze, improve gloss and fastness of the product.
For ceramic, enamel glaze, boron oxide is good fluxing agent and network formation. It can form the glass (at low temperature), and improve glaze adaptability, lower viscosity and surface tension, increase the refractive index, improve the mechanical strength, durability, wear resistance, it is the important part in the lead-free glaze. High boron frit aging fast, a smooth glaze, is advantageous to the color. In fast firing glaze ceramic frit, B2O3 with boric acid is introduced into, to ensure the requirement of low sodium content.
Pharmaceutical industry: used in the production of boric acid ointment, antiseptic, astringent, preservative, etc.
Metallurgy: used for production of boron steel additives, cosolvent, so that the boron steel with high hardness and good ductility. Boric acid can prevent the metal welding, brazing and set of welding surface oxidation. It is also a boron alloy materials.
Deliming leather: used for bare skin surface, and prevent the surface of the leather tannage again after resistant.
