As the Material of Filter Bags – Glass fiber is a traditional and common material for filtering. It is the most economical high-temperature filter material. According to the different composition of the glass, glass fiber can be divided into two types, C (medium alkali) glass fiber filter material and E (alkali-free) glass fiber filter material.
Glass fibers have outstanding high-temperature resistance, which is shown that it can still be work at the temperature of 260℃ with neutral alkali or 280℃ with alkali-free for a long time. And it is found that the highest tolerant temperature might be 350℃.
Besides the above, the glass fiber has excellent tensile strength and corrosion resistance. Its tensile strength is higher than other natural and synthetic fibers. And it can resist the corrosion of most acids except hydrofluoric acid.
The surface of the glass fiber is quite smooth, which means its filtration resistance is low. That is a benefit to peel dust. And the glass fiber does not burn or deform. And when the glass fibers are treated with different surface treatment agents, they will have the advantages of softness, smoothness, hydrophobicity, dew resistance and low shrinkage.
