Fiberglass Composite (FMS) Needle Felt Filter Bags
The glass fiber composite film covered needle felt filter bag
combines the advantages of glass fiber and chemical fiber,
overcomes the shortcomings of single material, and makes a new type
of composite filter material with high performance and high cost
performance.
The surface layer of glass fiber composite film covered needle
punched felt filter bag is needle punched with excellent chemical
fiber + alkali free glass fiber and high-performance glass fiber
base cloth. The fine denier fiber has good flexibility and holding
force, which can significantly improve the composite fastness and
overall strength of the filter material.
The base cloth of glass fiber composite film covered needle felt
filter bag shall be monofilament with diameter less than 5 μ M fine
ultra-fine alkali free glass fiber yarn, woven into high-strength
glass fiber base cloth to ensure that the filter material has
sufficient mechanical strength; After the pretreatment process, the
high-performance glass fiber base cloth with excellent physical and
chemical indexes and stable size is made.
After the composite filter material is made by the post-treatment
process, the unique post-treatment production process of Hongsheng
company and the "polytetrafluoroethylene (PTFE) mixed solution
needle" are used to impregnate the product as a whole according to
the post-treatment formula of the current working condition, and
then after high-temperature sintering treatment, the fiber surface
is wrapped to form a layer of PTFE protective film, which greatly
improves the oxidation resistance, corrosion resistance,
temperature resistance and dimensional stability of the filter
material; Enhance the hydrophobicity of the filter material,
improve the filtration accuracy of the filter material and prolong
the service life of the filter material.
Compared with the ordinary filter bag, the filter bag after PTFE
impregnation and eptef coating has the characteristics of not easy
to block the paste bag, easy to peel off the dust and low dust
emission concentration, which improves the filtration accuracy of
the filter material, so the dust purification efficiency is high
and stable.
The service life of the cloth bag is prolonged and the ash cleaning
cycle can be prolonged, so it can save a lot of energy consumption
and maintenance costs.
The characteristics of glass fiber composite membrane covered
filter bag are as follows:
(1) The filter material adopts excellent polyester fiber, which has
good jitter when cleaning the dust, and the dust is easy to peel
off; High porosity, good air permeability, high dust collection
efficiency and long service life;
(2) High strength and low elongation industrial silk is used as
base cloth to greatly improve the strength;
(3) PTFE microporous membrane is used to reduce the pore size, high
porosity and high filtration precision;
(4) Excellent glass fiber + chemical fiber are selected to enhance
the acid and alkali resistance, hydrolysis resistance and wear
resistance of the filter material;
(5) PTFE impregnation and other post-treatment processes of the
filter material improve the waterproof and oil proof performance;
(6) It is applicable to a wide range of working conditions, low
energy consumption and low maintenance cost;
