Product Advantages: low iron ion content and less impurities
In the glass fiber raw materials, boric acid plays an important role. Boric acid is an important co-solvent, which can accelerate the clarification of glass and reduce the crystallization ability of glass; it can improve the tensile capacity, impact strength and hardness of glass; it can reduce the thermal expansion coefficient of glass and improve the thermal stability of glass. Improve the tensile strength of the glass and increase the surface hardness. It can reduce the fastness of molten glass when the temperature is high, and increase the viscosity when the temperature is low. Therefore, glass with high boron content has a relatively narrow molding temperature range. When mechanized molding, the molding can be improved. speed. Boric acid can also increase the refractive index of the glass. When the lead content is the same, the boron-containing glass has better gloss than the boron-free glass.
But, due to the particularity of the glass industry, the requirements for the content of boric acid and the amount of control of other element ions are very high, and it is difficult for ordinary industrial boric acid to meet industry standards. Therefore, we repeatedly experimented and improved from the production of raw materials to the production process, and finally produced this special boric acid for the glass industry that satisfies customers. Not only can it significantly improve the heat resistance of the glass, increase the mechanical strength, and shorten the melting time, but also Improve the transparency of glass and increase product gloss. In actual use, it has also been well received by customers.
