Abstract
The utility model discloses a high strength acupuncture felt, including flaky base cloth layer and attached to the last composite bed and the lower composite bed of the upper and lower both sides in base cloth layer, the compound formation of fibre web that the composite bed was formed go up by at least two -layer alumina silicate fibre and glass fiber intermeshing, the composite bed is by nanofiber layer and the compound formation of microporous membrane down. The utility model discloses middle and upper composite bed is formed by the fibre web complex that at least two -layer alumina silicate fibre and glass fiber intermeshing formed, utilizes alumina silicate fibre and glass fiber's fire -retardant, temperature resistant characteristic, strengthens the high temperature resistant effect of acupuncture felt, the composite bed is formed by nanofiber layer and microporous membrane complex down, and the intensity of acupuncture felt is improved on the nanofiber layer, and the surface covering microporous membrane improves the oxidation resistance on nanofiber layer, further improves the intensity on nanofiber layer.
Description
Technical field
The utility model relates to a kind of Nomex, specifically a kind of high strength Nomex.
Background technology
The filtrate mainly continuous glass fibre coated filter material of existing application waste heat top pressure power generation, its surface uses PTFE film coating technique section to reach filter criteria, but the fine and closely woven flow reduced in the gas unit surface unit time seriously due to air void, add the burden that equipment runs simultaneously, simultaneously owing to its wear resistance of continuous glass fibre coated filter material is poor, it may also be useful to the life-span is also poor. Cause the normal operation that this filtrate cannot be long-time in dedusting of blast furnace gas purification waste heat top pressure power generation.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, it is provided that a kind of intensity height, the Nomex that heat resistance is good.
Technical scheme: high strength Nomex described in the utility model, the base cloth layer comprising sheet and the upper composite bed being attached to the upper and lower both sides of described base cloth layer and lower composite bed, described upper composite bed is compounded to form by least two layers of aluminium silicate fiber peacekeeping glass fibre fibre web formed that mutually tangles, and described lower composite bed is compounded to form by nanofiber layer and microporous membrane.
The utility model further preferably technical scheme be, described nanofiber layer be carbon nanofiber criss-cross arrangement formed fibrous reticulum.
Preferably, the single fine diameter of described carbon nanofiber is 10 ~ 100nm.
Preferably, described microporous membrane is the eptfe membrane through two-way stretch.
Preferably, described base cloth layer is the grid cloth that silvalin mutually tangles and formed.
Preferably, the thickness of described base cloth layer is 0.5 ~ 1mm.
Preferably, the aperture of described upper composite bed is 10 ~ 20 ��m.
Useful effect: in the utility model, upper composite bed is compounded to form by least two layers of aluminium silicate fiber peacekeeping glass fibre fibre web formed that mutually tangles, and utilizes fire-retardant, the temperature-resistance characteristic of aluminium silicate fiber peacekeeping glass fibre, strengthens the high-temperature resistant result of Nomex; Lower composite bed is compounded to form by nanofiber layer and microporous membrane, and nanofiber layer improves the intensity of Nomex, surface coverage microporous membrane, it is to increase the oxidation-resistance of nanofiber layer, improves the intensity of nanofiber layer further.
Accompanying drawing explanation
Fig. 1 is the structural representation of high strength Nomex described in the utility model.
Embodiment
Below by accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1:A kind of high strength Nomex, comprises the base cloth layer 1 of sheet and is attached to the upper composite bed 2 of the upper and lower both sides of base cloth layer 1 and lower composite bed 3, as shown in Figure 1:
Base cloth layer 1 be silvalin mutually tangle formed thickness be the grid cloth of 0.5 ~ 1mm.
Upper composite bed 2 is compounded to form by least two layers of aluminium silicate fiber peacekeeping glass fibre fibre web formed that mutually tangles, and fibre web aperture is 10 ~ 20 ��m.
Lower composite bed 3 is compounded to form by nanofiber layer and microporous membrane, and wherein, nanofiber layer is that carbon nanofiber criss-cross arrangement forms fibrous reticulum, and the single fine diameter of carbon nanofiber is 10 ~ 100nm; Microporous membrane is the eptfe membrane through two-way stretch.
Although as mentioned above, it is necessary, represented with reference to specific preferred embodiment and described the utility model, but it shall not be construed as the restriction to the utility model self. Under the spirit and scope prerequisite of the present utility model not departing from claims definition, it can be made various change in the form and details.
