In bag dust collecting, the bag usually
acts as the heart of bag filter. What kinds of smog that the bag filter can treat
depends on the material of bag filter. At normal working temperature,
the bag filter made from dacron, polypropylene fiber and other
chemical fiber can be qualified. Moreover, at the situation of high
working temperature, like chemical industry & coke
blast-furnace, the bag filter must be made from heat-resisting
material. First, these fume and dust is conductive and inflammable
so bag filter is better; Second, the cost of reducing the
temperature is very high, and the space is also limited; Third, the
component sulfur has acid dew point, so we have to do the treatment
at high temperature.

Remark:
1、Attachment
for the performance index of METAMAX heat-resisting needle-punching
filter felt.
2、METAMAX
is a general designation of NOMEX made by DuPont in America& CONEX made
by Teijin in Japan..
3、METAMAX
needling thread produced by our company has high strength, good
abrasive resistance and heat resisting even up to 260℃. So it is
the appropriative needling thread for METAMAX pocket filter.
