Abstract
It gathers dust cloth bag the present invention provides a kind of high temperature resistant Nomex, including internal skeleton and the filter layer being wrapped on skeleton, the filter layer is the blended fabric of glass fibre, polyimide fiber, polytetrafluoroethylene (PTFE) and basalt fibre, the content of glass fibre in the filter layer is 30-40 parts by weight, the content of polyimide fiber is 20-30 parts by weight, the content of polytetrafluoroethylene (PTFE) is 10-20 parts by weight, and the content of basalt fibre is 10-20 parts by weight.High temperature resistant Nomex of the invention gathers dust in cloth bag, due to basalt fibre have intensity height, high temperature resistant, performance corrosion-resistant, elongation percentage is low, the high temperature resistant Nomex of preparation gather dust cloth bag can high temperature resistant, can be used for a long time at 300 degrees Celsius.
Description
Technical field
It gathers dust cloth bag the present invention relates to a kind of high temperature resistant Nomex, belongs to accessory technical field of gathering dust.
Background technique
Bag filter is most popular a kind of dust-precipitator in cement industry.Its effect to dustshot (1 μm~5 μm)
Rate can also remove 1 μm even 0.1 μm of grit 99% or more.The adaptability of bag filter is stronger, not by dust ratio
The influence of resistance, also there is no other pollution problems can remove in gas simultaneously under the conditions of choosing filter aid appropriate
Gu, two pollutants of gas.Due to this feature, it is substantially all at all discharging fugitive dust points using bag type dust collection in cement industry
Device.
There are countless interlaced fibre covers on the filter cloth surface of sack cleaner, is greater than filter cloth eyelet in gas
Grit is acted on by inertia force, is kept off and sunk by filtration resistance, gas is then flowed through from fiber cloth hole.Grit is trapped in filter cloth surface or seam
Between gap, grit filter layer is formed, the void ratio filter cloth eyelet that this layer of grit layer is formed is small, so it, which is played, collects smaller grit
Effect.With the thickening of this layer of grit layer, filter cloth permeability is reduced, and resistance increases sharply, and purification efficiency also reduces, at this time
Deashing is needed to handle.It is required that filter cloth materials have 20~50 microns of 5~10 microns of aperture and surface villus aperture.Should also have
Gas, tension and shear resistance, also require good resistance to mild corrosion resistance sometimes, and quality is uniform.Common filter cloth materials
There is the animal and plant fibers fabric such as cotton, tussah silk, wool.Nylon, Orlon, terylene, glass fibre etc. is gradually adopted to have in recent years
Machine, inorganic artificial fibres' fabric or its blended product.Existing chain cloth performance or incomplete, is not applied for various building rings
Border.
Summary of the invention
The purpose of the present invention is to overcome the deficiencies of the prior art, provides a kind of high temperature resistant Nomex and gathers dust cloth bag.
High temperature resistant Nomex of the invention gathers dust cloth bag, including internal skeleton and the filter layer being wrapped on skeleton, institute
The filter layer stated is the blended fabric of glass fibre, polyimide fiber, polytetrafluoroethylene (PTFE) and basalt fibre, the filtering
The content of glass fibre in layer is 30-40 parts by weight, and the content of polyimide fiber is 20-30 parts by weight, polytetrafluoroethylene (PTFE)
Content be 10-20 parts by weight, the content of basalt fibre is 10-20 parts by weight.
Preferably,
The content of glass fibre in the filter layer is 35 parts by weight, and the content of polyimide fiber is 25 weight
Part, the content of polytetrafluoroethylene (PTFE) is 15 parts by weight, and the content of basalt fibre is 15 parts by weight.
High temperature resistant Nomex of the invention gathers dust in cloth bag, since basalt fibre has intensity height, high temperature resistant, corrosion resistant
Erosion, the low performance of elongation percentage, the high temperature resistant Nomex of preparation gather dust cloth bag can high temperature resistant, can make for a long time at 300 degrees Celsius
With.
