We also can finish them with Teflon bathing and membrane. Our
polyester needle felt adopt sound needle punching nonwoven
workmanship, with the property of stable physical dimension, easy
cake release, good air permeability, widely used for industrial
dust collection and liquid filtration, etc.
After water-oil repelled treatment, can be use in the circumstance
of moisture and oil mist for a long time. After the PTFE membrane
treatment the felt will with the property of smooth surface, easy
cake release, high filter efficiency, save energy, long life, etc.
Note: 1. Special specification can be customized.
2. maximum width:2.3meters.
3. both filter cloth rolls and filter bags are available from Suita
Filters.
We usually receive the questions from end users that why the filter
bags need to make the finish treatment of water oil repellent? The
answer is for some special circumstance, this treatment will
improve the performance and prolong the using life of filter bags.
Generally speaking, following situation we consider it easy to
dewing:
When the filter bags meet the dew, while unfortunately the filter
bags is without water &oil repellent, the dust will mixed with
the dew and glued on the wall of the filter bags, so that will make
the filter bags blocked and increase the pressure in the bag filter
house, so the filter efficiency will lower and energy consumption
will increase sharply, that will shorter the using life of the
filter bags obviously.
Further more, once there are some acid or alkali material in bag
filter house, when they meet the dew which will cause some chemical
reaction so that will engender some corrosive liquid which mixed
with dust and glue on the wall of the filter bags that will decay
the filter bags soon and also will increase the frequency to change
the filter bags
