Basalt Fiber Filter Bag
Basalt fiber high temperature filter bag adopt basalt roving, which has a good endurance of high temperature, alkali, acid and oxidation. The hydrophobic and dimensional stability feature of basalt fiber filter bag can satisfy the harsh dedusting environment, also can prolong the service life of basalt fiber filter bag.
Advantages:
1. With excellent heat-resistance, filter bag can be used quite a long time under 300℃(the operating temperature at a long term of fiberglass is 260℃, P84 is 240℃,aramid fiber is 200℃).
2. Good bug dust peeling property, low consumption for dust cleaning.
3. With good dimensional stability, contraction rate of fiber itself is zero when under the operating temperature.
4. Has a good performance of chemical and weather resistance. It has
5. Non moisture absorption. (The moisture absorption of basalt fiber is
1/8 of glass fiber.）
6. The validity of filtering can be as high as over 99.5%.
7. Can prolong the service life.
Application:
It was widely used in cement plant, iron and steel plant, heat-engine plant.
Specification:
127mm × 1500mm
127mm × 1150mm
130mm × 2450mm
And the specification also can be custom made.
