The present invention cooperates using so that gap is more uniform for paraffin using uramit as major porogen, especially logical
The heating of two steps is crossed, sky is avoided and is prematurely formed, the uniformity in the hole also fully ensured that, this does not see in the prior art, especially
It is follow-up hydrothermal processing, this is that the present invention is pioneering, substantially avoids the influence of impurity in hole, and several combinations produce obtained from
Product filter effect is excellent, and combines plastics composite, effectively can generate suction with particulate pollutant, even organic pollutant
Attached effect.
The present invention designs discounting formula structure in addition to creative in structure, improves the mechanical property and filtering of product
Effect mainly realizes fine efficient filtering and mechanical property, service life by preparing raw material and preparation process
Greatly improve.Existing plastics chimney filter is all polypropylene or doping polypropylene injection molding preparation, because polypropylene is easy to process, phase
To cheap, but there is a problem of that apparent poor mechanical property, poor filtration effect, service life are short, the present invention reopens thinking, asks
Teach materialogy expert, design it is new prepare raw material and technique, although upper complicated compared with existing product in cost and preparation,
It is the filter effect with long service life and high-precision, positive and negative calculating is handled for the enterprise for using chimney filter
Same gas, cost of consumption are the 32% of existing product, can be calculated, and in simple terms, product of the present invention price is existing
3 times of product or so, but service life of the present invention is at least 10 times of existing product, it is easy to it calculates, after practical application, the present invention
It is still low cost.
Chimney filter processing gas needs to have excellent wear-resisting property, strainability, heat resistance, it is also necessary to excellent power
Learn performance, flame retardant property；Existing product generally all addition inorganic material are to improve some performances, but organic-inorganic product is natural
Heterogeneity cause to be modified the defect that not can avoid still between two-phase anyway, the short time is not seen, but in high temperature height
Under wet gas constantly washes away, defect point can constantly expand, and lead to damage of product, and the invention avoids this problems, this is also this
Long one of the reason of invention life of product, but by reasonable organic matter compatibility, obtained product still mechanical property, heat-resisting
Performance, wear-resisting property are excellent, do not reduce quality.
In the present invention, for synthesis mixture as high-strength, high-anti-friction material of main part, polytetrafluoroethylene (PTFE) is mechanical strong to improve
Degree and processing performance simultaneously reduce coefficient of friction；The self-lubricating of organo-silicon compound and organosulfur compound to improve product
Property, while 3- aminopropyltriethoxy dimethoxysilane can also improve the affinity between product composition, polyoxyethylene caster
Oil increases activity, improves the reactivity between product；The present invention is not to reach technical effect by a kind of or two or three kind of substance,
But gas chromatography is organically subjected to compatibility, synergistic effect is played after reaction, can just obtain excellent technical effect, such as
The cooperation of silicon and sulphur not only improves product heat resistance and also gives good flame retardant property, such as based on the cooperation of acid anhydrides, ester, ketone
Material provides excellent mechanical support；Etc..
Plastics composite of the invention can be in wider hardness range elasticity with higher and intensity, excellent wear-resisting
Property, oil resistivity, fatigue durability and anti-vibration resistance, antiseptic property is good after end hydroxy butadiene is reacted with Emulsifier EL-60；
Using resin combination as major ingredient, reactive compound is selected to adjust reactivity and stability, by organosilicon, Organic fluoride characteristic,
Enhance the wear resistence of itself, degrees of fusion, mobility between small molecule guarantee each component, so that performance reaches optimal state；
In addition to good adhesive property, also there is enough intensity and good wear-resisting property between each resin.Generally, it is added
The intensity of epoxyn can be improved in certain inorganic filler, and can also improve other property of adhesive
Can, it is corrosion-resistant, wear-resisting, thermally conductive after ethylene vinyl acetate is reacted with triethylene tetramine, end hydroxy butadiene
Property it is good, thermal expansion coefficient is low, can play skeleton and wear-resistant effect, Emulsifier EL-60, maleic anhydride grafting can be with
Reduce coefficient of friction, product can be made to become smooth, coefficient of friction becomes smaller.
Due to the above technical solutions, the present invention has the following advantages over the prior art:
Strengthening part is creatively arranged in the present invention in chimney filter, avoids under the intensity as caused by overall gear structure
Drop, the problem of stability difference, and by limiting strengthening part various parameters, reach not only stable chimney filter, but also do not influence gas flowing
Effect；Tooth top structure is equipped among chimney filter pedestal for the first time, by the inside tooth top in chimney filter bottom, when air pulse undershoot to tooth top
When structure, it is effectively formed rebound, plays the role of distributing air-flow, increases pulse lavage effect；Sintering of plastics chimney filter is not necessary to simultaneously
There is inner support frame, it is not easy to wear, cost can be reduced, mitigates chimney filter weight while promoting filter effect, overcomes existing skill
The problem that art chimney filter can aggravate；Discounting area increases, and increases filter area；In addition equipment reduces occupied area, can also reduce and make
Valence cost；Height by changing section number of teeth mesh, gear teeth tips part adjusts filtration contact area, using etc. static pressure at
Type can not only guarantee that the deformation comparison of product is small, can also require according to product design, change the cross section parameters of chimney filter,
To increase the filtration contact area of chimney filter to a certain extent, to improve the filter effect or save the cost of chimney filter.It is designing
In the case where identical filter area, identical filtering surface can be reached by reducing the dosage of chimney filter or reducing the caliber of chimney filter
Product, and space occupied by the screen pipe of more slim pipe diameter can be fewer, can thus reduce the volume of chimney filter, and saving steel is used
Amount, to generally save the manufacturing cost of filter plant；Plastics chimney filter structure composition is reasonable, and disassembly is easy, and is applicable in a variety of mistakes
Filter occasion；Material forms for sintering of plastics, and intensity is big, and sintering precision is high and wearability is strong；Filter type is absorption, surface filtration
It is combined with in-depth filtration, work principle of filter is mainly inertial collision, diffusion and retention, relative to cyclone dust removal, stratum granulosum mistake
Filtering dust collecting, electrostatic precipitation, wet sprinkling dedusting etc., not only high dust collection efficiency, filtering accuracy are high, obvious heat of smoke utilization rate is high, and
And use scope is wide, high temperature resistant, corrosion-resistant.
Plastics chimney filter disclosed by the invention, which belongs to, can clean again using environmentally friendly machine, and cleaning effect is best；It can be direct
Traditional filter bag equipment is replaced, is not necessary to modify existing dust-collecting equipment, while service life of equipment is long, service life can be greater than tradition
It 10 times of type or more, not only summarizes, also can determine from accelerating damage to test, the wear life of product of the present invention is existing from actual motion
There are 12.5 times of product；Reduce operation operating cost, the dust removal process suitable for high temperature, acid-base property coal-fired flue-gas.
