Product introduction:
High SiO2 Content Silica Pebbles for glass fiber have good hardness and low wear loss. It has SiO2 over 99%, works well as grinding media ball for not only glass industry. Used well for ceramic industry, chemical industry, white cement industry,etc.
Technical indicator:
SiO2 | ≥99.31% | Volume density | ≥2.66g/cm3 |
Al2O3 | ≤0.36% | Hardness | Around 8 mohs |
Fe2O3 | ≤0.018% | Porosity | ≤0.38% |
CaO | 0.09% | Actual abrasion rate | ≤1.35 |
MgO | 0.04% | Color | Grey and White |
For Glass fiber, silica pebbles size range from 3-5cm/4-6cm/6-8cm are widely be chosen.
Advantage of our silica pebbles
*High hardness
*Low wear loss
*High SiO2 content with low Fe2O3
*Stable chemical content
What is the infect if Fe2O3 is high for glass fiber?
Firstly, iron oxide can affect the transparency of glass fibers. Glass fiber usually needs to have high transparency in order to be widely used in fields such as construction, vehicles, and ships. If the content of iron oxide is too high, it will lead to a decrease in the transparency of glass fibers, affecting their aesthetics and application value.
Secondly, iron oxide can also have an impact on the strength and hardness of glass fibers. Glass fiber usually needs to have high strength and hardness in order to withstand the application requirements of different fields. If the content of iron oxide is too high, it will damage the strength and hardness of glass fibers, reduce their service life and safety performance.
Packing & Delivery
silica pebbles usually deliverd by sea.
25tons-27tons for each 20'GP can be loaded.
