Abstract
A high-temperature composite spunlaced felt comprises base cloth, a fiber mesh and a treatment layer. The high-temperature composite spunlaced felt is characterized in that continuous glass fibers and long polytetrafluoroethylene fibers are stranded and twisted to form composite yarns, the base cloth of the spunlaced felt is made of the composite yarns, short fibers including short glass fibers, aramid fibers, terylene fibers, aromatic polysulphone fibers, P84 fibers, polytetrafluoroethylene fibers and the like are compounded to form the fiber mesh which is implanted into the base cloth in a spunlaced manner, a felt blank is prepared after dewatering and is impregnated by temperature-resistant anti-corrosion finishing liquor, and then the felt blank is dried. The surface of the felt blank impregnated by the finishing liquor is covered by the treatment layer, and the thickness of the treatment layer ranges from 0.3mm to 0.5mm. The high-temperature anti-corrosion spunlaced composite filtering material is used for manufacturing a cloth bag of a dust remover suitable for running under high-temperature strong-corrosion conditions, and overcomes the shortcomings that a filtering material processed by a needle punching technique is infirm in structure, a fiber mesh is easy to fall off, strength loss of fibers is high, and the filtering material is short in service life in a high-temperature and high-corrosion environment.
Description
Technical field
The utility model belongs to filtrate and makes the field, relates to a kind of high temperature antioxygen composite filter material, particularly relates to the composite spunlaced felt of a kind of high temperature.
Background technology
The filtration of industrial fumes is a large amount of fine dusts, is retained down through certain method, thereby is discharged into the air of cleaning in the atmosphere.So just need deduster, sack cleaner is a most widely used equipment in the industrial dedusting, is exactly the cloth bag made from woven cloth or Nomex one by one; As filter element; Realize the separation of gas-solid body, its advantage is that filtering accuracy is big, and dust is escaped few; Shortcoming is that cloth bag receives the dust property effect big, and maintenance cost is high.Electric cleaner is the sucking action with the high pressure positive and negative electrode, collects dust, and speed is fast, does not receive the restriction of temperature, but has high input, and energy consumption is high, and filtering accuracy and efficient are low.In order to address the above problem; Electric-bag complex dust collector arises at the historic moment, for electric-bag complex type dust remover, because its electric precipitation part produces the ozone of strong oxidizing property when electrion; The cloth bag cloth bag partly of later process has been proposed the requirement of high-temperature oxidation resistant; Experiment and practical application prove that high temperature fiber filtering materials such as present glass, PPS (polyphenylene sulfide), P84 are difficult to bear the corrosion of high temperature ozone and damage, and cause the dust discharging that exceeds standard in a large number.
Summary of the invention
For overcoming the weak point of prior art, the utility model provides the composite spunlaced felt of sack cleaner filtering material high temperature of operation under the high etching condition of a kind of suitable high temperature.
The utility model solves the technical scheme that its technical problem adopted:
The composite spunlaced felt of a kind of high temperature comprises base cloth, fleece, processing layer, it is characterized in that:
Continuous glass fibre and the Split Down of polytetrafluoroethylene (PTFE) long fibre added be twisted as complex yarn, use the base cloth of this yarn weaving as water thorn felt; On base cloth, the water thorn is implanted the fleece that is combined into by short fibers such as staple glass fibre, aramid fiber, terylene, fragrant sulfone synthetic fibre, P84, polytetrafluoroethylene (PTFE), makes the base felt after the dehydration.
For further improving the physicochemical property of this filtering material, above-mentioned base felt needs after the dressing liquid impregnation process, to dry.
Described dressing liquid is made up of polytetrafluoroethyldispersion dispersion, perfluoro carboxylic acid, benzyl silane coupler, organic siliconresin and water; Water thorn felt is 0.5～3.0m/min through the speed of dressing liquid, and bake out temperature and time are 150 ℃～230 ℃, 15～35min.Processing layer is covered on base felt top layer after described dressing liquid is handled, and thickness is 0.3～0.5mm.
Described water thorn is implanted, and is after glass fibre, fragrant sulfone synthetic fibre, aramid fiber, terylene, P84, polytef flocks are mixed, to be carded to fleece; This fleece is placed on the positive and negative of base cloth, is clipped in the middle base cloth, send into spun-laced machine after prewetting; The fine water jet of the multiply that high pressure produces sprays fibre web, after water jet passes fibre web, receives the rebound effect of holding lace curtaining or rotary drum; Intert fibre web once more, water jet directly impact and the double action of the current that rebound under, the fiber in the fibre web is subjected to displacement, interts, entanglement, obvolvent; Form numerous flexible entanglement point, thereby fibre web is fixed on the base cloth, the dehydration back forms the base felt.
Described glass fibre and polytetrafluoroethylene fibre are long fibre during as the composition fiber of base cloth.When glass fibre and polytetrafluoroethylene fibre are long fibre; Weave cotton cloth after processing the Split Down composite yarn; The cloth of knitting stings felt as water, when glass fibre, fragrant sulfone synthetic fibre, aramid fiber, terylene, P84, when polytetrafluoroethylene fibre is short fiber, with several kinds of fiber mixing; Be carded to fleece, its ratio is: glass fibre: 0-60%, fragrant sulfone synthetic fibre: 0-15%, aramid fiber: 0-100%, terylene: 0-5%, P84:0-100%, polytetrafluoroethylene fibre: 0-100%.
The dressing liquid of described base felt impregnation process is: polytetrafluoroethyldispersion dispersion: 12-20%, perfluoro carboxylic acid: 1.5-3.5%, benzyl silane coupler: 1.0-3.0%, organic siliconresin: 0.3-2.0%, water: surplus.
Described continuous glass fibre is the inorfil by glass.Its main component is silica, aluminium oxide, calcium oxide, boron oxide, magnesia, sodium oxide molybdena etc.; According to what of alkali content in the glass; Can be divided into alkali-free glass fibre (sodium oxide molybdena 0%～2%; Belong to aluminium borosilicate glass), medium-alkali glass fibre (sodium oxide molybdena 8%～12% belongs to the boracic or the soda lime glass of boracic not) and high alkali glass fibre (sodium oxide molybdena more than 13%, genus soda lime glass).The utility model is described to be that what be fit to make filtering material is alkali-free glass fibre.Be characterized in that heatproof is high, do not fire, anti-rotten, heat insulation, tensile strength is high, electrical insulating property is good.
Described polytetrafluoroethylene fibre; It is by the macromolecular compound of tetrafluoroethene through being polymerized; By polytetrafluoroethylene (PTFE) is raw material, cutting or fibrillation through spinning or after processing film and a kind of synthetic fibers of making, and heatproof is excellent; Can long-term work under+250 ℃ to-180 ℃ temperature, have excellent chemical stability, corrosion resistance.
The usefulness of the utility model is:
The anti-rotten water thorn composite filter material of a kind of high temperature involved in the present invention is continuous glass fibre and the Split Down of polytetrafluoroethylene (PTFE) long fibre to be added be twisted as complex yarn, uses this yarn weaving to sting the base cloth of felt as water; On base cloth, the water thorn is implanted by compound fleeces of short fiber such as staple glass fibre, aramid fiber, terylene, fragrant sulfone synthetic fibre, P84, polytetrafluoroethylene (PTFE), makes the base felt after the dehydration; The base felt again through the anti-rotten inorganic agent impregnation process of heatproof, is produced the deduster cloth bag filtering material that moves under the suitable high temperature strong corrosion condition, and the filtering material structure that overcomes needling process processing is not firm; Fiber Netease comes off; The fibre strength loss is big, under the high rotten environment of high temperature, and the drawback that service life is short; Reduce dust emission and dedusting cost, realize the production of environmental protection of enterprise economized.
