The filter
bag is a part of the filter which is widely used and has a relatively frequent
replacement frequency. It can be said to be a relatively core part in the
process of filter filtration, and the filtering effect mainly depends on the
material, the weaving method, and the subsequent processing.
Common
filter bags are made of natural and synthetic fibers. Natural fibers include:
cotton, hemp, silk, wool, etc. These filter bags are short in fiber and easy to
swell in water, so they have strong performance in retaining impurities, and
the filtering effect is good, but the highest safe temperature is low, and it
is not resistant to acid. Alkali, not suitable for use in high temperature
corrosive conditions. There are many types of synthetic fibers, such as nylon,
polyester, acrylic, polyester, etc., which have higher safety temperature and
chemical resistance than natural fibers.
In the weaving, the yarn can be selected from
monofilament yarn, multifilament yarn and short fiber yarn. The filtration
speed of the monofilament yarn filter cloth, the dryness of the filter cake and
the ability to remove the cake are strong, and the filtrate transparency and
use of the short fiber yarn filter cloth are used. The life is higher, and the
various properties of the multifilament yarn are between the above two. In the
production of the filter cloth, a weaving method or a non-woven method can be
used. The weaving method is to weave the yarn into a filter cloth by using a
certain weaving rule, and can be divided into plain, twill, and satin according
to different weaving rules. Instead of weaving, wool or synthetic staple fibers
are mechanically pressed into a "cloth" in which a resin binder can
be added to ensure firmness. In terms of performance, although the filtering
speed of the weaving filter bag is not as good as that of the non-woven filter
bag, the filter cake drying rate, the cake breaking ability and the service
life have strong advantages.
It can
be said that there are many types of filter bags. When selecting the type, it
is necessary to choose according to the requirements of the working conditions
and the nature of the filtrate. Do not blindly follow. RKSfluid filter bags can
be selected according to your requirements.
