Usage:
Boric acid is used extensively for the glass industry, in particular E-glass fibers.In the enamel, ceramic industry, products used to enhance the gloss and fastness. Can be used for medicine and wood preservation. Fungicides can be done in agriculture, pesticides, and trace element fertilizers. Boric acid is produced diboride matrix material, and its metal welding, leather, precious stones, electronics, defense and scientific research departments have widely applied.
