Abstract
The utility model relates to a high temperature resistant high silica glass fiber punched felt, belonging to nonwoven fabrics technical field. The punched felt comprises a multilayer felt net carded and lapped with fibers, wherein, the fibers are high silica short silk fibers; the vertical short silk fibers formed by punching are alternately interwoven between the layers of the multilayer felt net; the vertical short silk fibers are mutually connected with the fibers at each layer of the felt net. As high silica is high temperature resistant and corrosion proof, and vertical and crossed short silk fibers formed between the layers of the felt net make the surface of the punched felt porous, the punched felt of the utility model not only has good temperature resistant and corrosion proof performance, but also has the characteristic of gas and liquid preferential adsorption, which is good in adsorbing and filtering capability, and very suitable to be used as the filtering and dedusting materials for high temperature and corrosive smoke dust as well as high temperature insulating materials.
Description
Technical field
The utility model relates to a kind of fiber needled felt, and especially a kind of high-temperature fibre Nomex belongs to the bondedfibre fabric technical field.
Background technology
Along with the enhancing of people's environmental consciousness, the range of application of Nomex constantly enlarges.Understand according to the applicant, fields such as high-temperature dust removal, purification, heat insulation, insulation are more and more higher to performance demands such as existing Nomex, the heatproof that comprises fiberglass needled mat, chemically stable, anticorrosion, absorption.Existing procucts are because the restriction of material and fiber self structure can't be satisfied above-mentioned needs better.
Summary of the invention
The purpose of this utility model is: propose a kind of heatproof, chemically stable, resurrection glass fibre Nomex that antiseptic property is good.
In order to reach above purpose, the applicant is by discovering various fibrous materials, and high silica fiber can not melt below 1650 ℃.Its heat resistance reaches 1000～1100 ℃.After temperature surpasses 980 ℃, become fragile owing to crystallization makes fiber, but its physical aspect heat-proof quality changes not quite, so during as heat-barrier material, its serviceability temperature can reach 1370 ℃.The chemical stability of high silica fiber is fine, ability all acid and erosions of moderate strength alkali except that hydrofluoric acid and phosphoric acid.High silica fiber also has excellent electric insulating energy and dielectric properties.
In view of the above, the applicant has proposed following technical scheme: the resurrection glass fibre Nomex, the multilayer feltwork that is become by fiber combing, laying constitutes, wherein said fiber is high silica staple fiber, the vertical staple fiber that the acupuncture that alternates between described each layer of multilayer feltwork forms, described vertical staple fiber and each layer of feltwork fiber connect mutually.
Because high temperature resistant, the anticorrosion of high silica fiber, chemical stability are good, the vertical intersection staple fiber that acupuncture forms between each layer feltwork makes Nomex porous surface matter, and adopt the technology manufacturing of acidleach after the first acupuncture, therefore the utility model Nomex not only has good heatproof, antiseptic property, characteristic with gas, liquid selective absorption, and debris is few, the original fibre length of basic maintenance, intensity improves, and therefore very is suitable as the dust removal by filtration material of high temperature, corrosivity flue dust.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the cross section structure schematic diagram of an embodiment of the utility model.
The specific embodiment
Embodiment one
The resurrection glass fibre Nomex of present embodiment is at first founded and wire drawing as shown in Figure 1.For the friction in the weaving process after fiber is reduced, fiber surface is coated continuously, uniform protective film.Then, it is 40～80 the short silk of high silica that resurrection glass fibre long filament weak point is cut into length, use corresponding special equipment shredding again, combing, lapping, with very thin feltwork laying from level to level, to reach desirable thickness, by needing machine feltwork is carried out repeated puncture at last, this Nomex as shown in Figure 1 as a result, by the combing of high silica staple fiber, the multilayer feltwork 1 that laying becomes constitutes, the vertical staple fiber 2 that the acupuncture that alternates between each layer forms, these vertical staple fibers and each layer of feltwork fiber connect mutually, become the high silica acupuncture cotton (felt) with certain intensity.
After this, carry out leaching and handle, its main process is controlled certain temperature and time for the moulding felt is put into the acid colleciton groove that fills hot hydrochloric acid, passes through solution-treated, final drying, heat treatment after water cleans again.Moisture on the fabric fibre and charcoal can be removed like this.
Experiment shows, the high silica Nomex of present embodiment behind sintering, SiO
2Content can reach more than 96%, and its heat resisting temperature is generally 900～1000 ℃, and instantaneous temperature can reach 1400 ℃, and chemical stability is very high, and the erosion of the alkali of all acid and moderate strength also has excellent electric insulating and dielectric properties beyond energy hydrofluoric acid resistant and the phosphoric acid.Because the surface of high silica fiber is a porous matter, has the characteristic of gas, liquid selective absorption, be a kind of desirable filtering material therefore.
Particularly what deserves to be mentioned is, the resurrection glass fibre Nomex of present embodiment adopts the processing step of first acupuncture felt, back acidleach, therefore fiber embrittlement, the debris drawback how of having avoided original first acidleach, back acupuncture to cause, the resurrection glass fibre Nomex fiber of making is long, the intensity height, presentation quality is obviously improved.
Claims (2)
1. resurrection glass fibre Nomex, the multilayer feltwork that is become by fiber combing, laying constitutes, it is characterized in that: described fiber is high silica staple fiber, the vertical staple fiber that the acupuncture that alternates between described each layer of multilayer feltwork forms, described vertical staple fiber and each layer of feltwork fiber connect mutually.
2. according to the described resurrection glass fibre Nomex of claim 1, it is characterized in that: described fiber surface is coated continuously, uniform protective film.
