Product Name: Boric Acid *9%
MF: H3BO3
MW: *1.*3
CAS: *********3
HS Code: *********0
Einecs: ********2
Puirty: *9.5%***9.9%
Appearance:White crystalline powder or colorless
shiny pearl-like scales
Physical and Chemical Properties:
Heating caused by the boric acid **0 degrees, due to the constant
losing moisture, it first becomes borate, which has three variants,
respectively, melting point **6 degree, **1 degree and **6 degree.
Partial dehydration of boric acid to produce boric acid to an end
(as long as the temperature does not exceed **0 degree). And then
continue heating the water off the net generated by boron oxide.
Crystalline boron oxide at **0 ° C melting. Amorphous boron is no
fixed melting point, it begins to soften at **5 degree, **0 degree
all become liquid.
Application:
Glass and Fiberglass Industry: For the production
of optical glass, acid glass, organic glass and other high boron
glass and glass fiber, glass can improve the heat resistance and
transparency, improve the mechanical strength, reduced melting
time.
Enamel and Ceramics Industry: Porcelain enamel,
ceramic industry for the production of glaze, the glaze can reduce
the thermal expansion, reducing the curing temperature of glaze, to
prevent cracking and de-glaze, luster and improved products
fastness.
Pharmaceutical industry: For the production of boric acid
ointment, disinfectant, astringent, antiseptic, etc.
Inflaming Retarding:Added material in the borate can
change its oxidation to promote "carbon" formation. It can be flame
retardant. Boric acid and borax alone or together, to reduce the
celluloid insulation materials, wood, cotton mattress flammability
of child with special effects.
Metallurgy Industry: Boron steel for the
production of additives, solvent, so that the boron steel mill with
high hardness and good ductility. Boric acid to prevent metal
welding, brazing, welding sleeve surface oxidation. It is also
boron alloy materials.
Leather Industry: Gray off the surface for bare
skin, to prevent the surface of the leather after tanning and then
gray leaf spot.
Rust Industry:Boric acid as a rust inhibitor,
lubricant, and thermal oxidation stabilizer. It is added to the
lubricants, brake fluid, metalworking fluids, water treatment
chemicals and fuel additives.
Binder Industry: Boric acid is a component of
manufacturing corrugated binder, but also the manufacture of casein
and dextrin adhesive glue solvent. Hydroxy acid by crosslinks
greatly improved the wet adhesive strength.
Personal care products:State Pharmaceutical grade
(NF) boric acid used in cosmetics, hygiene products and medicines.
It is also mixed with borax buffer solution of pH. As a
crosslinking agent emulsified wax, also can be used as
antibacterial agents.
Nuclear industry:Boron**0 isotope is effective
thermal neutron absorber. Therefore, it is safe and nuclear power
plants in the control system is indispensable. Special Class (SQ)
boric acid in the nuclear industry, it can increase the proportion
of boron**0.
Chemical Industry
For the production of boric acid salts, such as sodium borohydride,
boric acid ammonium hydrogen, boron cadmium tungstate, potassium
borohydride.
Nylon intermediates in the production process, the boric acid from
the catalytic oxidation of hydrocarbons and to increase ethanol
production to generate ester, which prevents further oxidation
generates hydroxyl ketone or carboxylic acid. Fertilizer industry
for the production of the wick, boron-containing fertilizers.
