Matters need attention
After the needle felt is done with waterproof and anti-oil treatment, in order to maintain the integrity of the waterproof membrane, during the storage and transportation of the filter bag, it must be avoided that the surface of the filter bag is scratched with hard objects.
The melting temperature of the fluorine waterproofing agent is around 170 °C. Therefore, when using filter materials with treatment of waterproof and oil resistance by Fluorine waterproofing agent, operating temperature needs to be avoided to be above 170°C.
