Fiberglass is an inorganic fiber which is obtained by drawing fiberglass silk from a glass molten state when melting a glass frit at a temperature of 1300 to 1600 °C and rapidly quenching. The density of fiberglass silk is 2.54 g/cm3, and the tensile strength of the raw yarn is 160 to 275 kg/mm2. Glass silk can be divided into A glass, C glass, E glass, and S glass according to the composition. The most prominent features of fiberglass are high-temperature resistance, good dimensional stability and high tensile strength at break. In terms of chemical resistance, fiberglass is stable to other media except for hydrofluoric acid and high-temperature alkali. The disadvantage of fiberglass is that it has poor folding resistance and is generally not used on an oscillating or pulse system.
SINOSPARE offers fiberglass filter cloth filter bag and fiberglass needled felt filter bags to the global market.
Fiberglass Filter Cloth Filter Bag with the advantages of high-temperature resistance, corrosion resistance, dimensional stability, extremely small elongation and contraction rate and high strength.
Fiberglass Needled Felt Filter Bags has more advantages with its three-dimensional microporous structure than Fiberglass cloth filter bags, such as high porosity and low resistance used in high-speed, high-efficiency,high-temperature gas filtration working condition. Compared with other high-temperature resistant fiber felts, it has special advantages such as low price and high-temperature resistance. However, its running resistance is higher than other general chemical fiber high-temperature filter materials, and the filtration precision is slightly lower.
