Product Description
The three-proof anti-needle filter felt is "waterproof, oil-proof, _", that is, the "water and oil repellent" function is added to the _ needle-punched felt, which is suitable for occasions with large moisture content, such as Steel plant blast furnace pulverized coal injection, cement plant, power plant coal transportation system, etc.
1. High-strength and low-stretch industrial yarn is used as the base fabric, which greatly improves the strength.
2. The fine denier fiber is selected, the pore size is reduced, the porosity is high, and the filtration accuracy is high.
3. The use of excellent polyester fiber, acid and alkali resistance and hydrolysis resistance have been enhanced.
4. The surface treatment is smoother, with the surface filtering effect of the membrane filter material.
5. Low running resistance and energy saving.
