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.
