Na2B4O7.5H2O Sodium Tetraborate Pentahydrate for Glass Wool
1. Borax Pentahydrate Introduction
Borax pentahydrate, also known as disodium tetraborate
pentahydrate, is a crystalline form of borax composed of sodium,
boron, oxygen, and water molecules. It is chemical formula is
Na2B4O7.5H2O. Borax pentahydrate boron content is about 15% and
boron oxide content is more than 48%. Borax Pentahydrate is
commonly used in various industrial and household applications due
to its unique properties. It is known for its role as a cleaning
agent, as a flux in welding, as a buffering agent in chemical
laboratories, and even as a component in some cosmetics and
pharmaceuticals. Its ability to dissolve in water and form alkaline
solutions makes it versatile for a range of uses. With its
distinctive properties and wide-ranging applications, borax
pentahydrate plays a significant role in numerous industries and
daily activities.

3. Borax Pentahydrate Functions in Glass Wool and Glass Fiber
The application of borax pentahydrate in glass wool and glass fiber
is mainly reflected in improving the rebound rate and tensile
strength of glass wool. Specifically, borax pentahydrate can be
used as one of the raw materials for refractory insulation glass
wool. By adding an appropriate amount of borax pentahydrate, the
rebound rate and tensile strength of glass wool can be effectively
improved, thereby solving the problem of low rebound rate and
tensile strength of refractory insulation glass wool in related
technologies.
The specific mechanism of action of borax pentahydrate in glass
wool is achieved through its chemical composition and physical
properties. Borax pentahydrate can form a stable glassy substance
at high temperatures, which has good heat resistance and stability,
and can enhance the structural strength and fire resistance of
glass wool. In addition, borax pentahydrate can also improve the
insulation performance of glass wool, allowing it to maintain good
insulation effect in high temperature environments.
