Abstract
The utility model discloses a polyphenylene sulfite (PPS) fiber step-gradient high-temperature-resistant needled felt. The needled felt is of a layered structure and comprises intermediate basic fabric, a PPS fiber layer which is adhered on the upper surface of the basic fabric, and a PPS mixed fiber layer which is adhered on the lower surface of the basic fabric, and the upper surface of the PPS fiber layer is also provided with a PPS ultrafine fiber layer in a sticking way; the PPS fiber layer and the PPS mixed fiber layer are adhered onto the basic fabric in a needling way via a needling machine; the basic fabric is PPS fiber woven fabric; and the PPS mixed fiber layer is formed by mixing two different kinds of PPS fibers with different diameters. The PPS fiber step-gradient high-temperature-resistant needled felt has the beneficial effects that remarkable temperature resistance can be achieved, and the high temperature resistant range is from 120 to 190 DEG C; the porous structure of the product is changed in a gradient way, the friction property is low, and the filter effect is good; the chemical resistance and the hydrolysis resistance are strong; and the service life is long.
Description
[technical field]
The utility model relates to a kind of needled filtering felt, particularly the high temperature resistant Nomex of a kind of PPS fiber ladder degree.
[background technology]
Gas cleaning and dust that the filtration Nomex is used for the industries such as carbon black, iron and steel, non-ferrous metal, chemical industry, burning reclaim various sack cleaners, general Nomex can anti-temperature below 150 ℃, but the occasion more to flue gas, it is very fast that the deep layer of cutting easily filtrate owing to dust causes resistance to rise, so to the strainability that filters Nomex and higher requirement is arranged service life.
[summary of the invention]
The purpose of this utility model is to overcome deficiency of the prior art, and the PPS fiber ladder degree high temperature resistant Nomex of a kind of PPS of having superfine fibre layer as surface layer is provided.
The purpose of this utility model is achieved in that described Nomex is layer structure, it comprises middle base cloth, the PPS mixed fiber layer that sticks on the PPS fibrage of base cloth upper surface and stick on the base cloth lower surface, and the fibrolaminar upper surface of described PPS also is pasted with PPS superfine fibre layer;
In the said structure, described PPS fibrage and PPS mixed fiber layer stick on the base cloth by needing machine acupuncture;
In the said structure, described base cloth is that the PPS fibre machine is weaved cotton cloth;
In the said structure, described PPS mixed fiber layer is mixed by the PPS fiber of two kinds of different-diameters.
Compared with prior art, the beneficial effects of the utility model are:
One, significant temperature tolerance, high temperature resistant scope is 120-190 ℃;
Its two, the holes of products gauge structure becomes graded, frictional property is low, filter effect is strong;
Its three, anti-chemistry and resistant to hydrolysis ability are strong;
Its four, long service life.
[description of drawings]
Accompanying drawing is the high temperature resistant Nomex of PPS fiber ladder degree of the present utility model;
Reference numeral
1, base cloth; 2, PPS fibrage; 3, PPS mixed fiber layer; 4, PPS superfine fibre layer.
[specific embodiment]
Below in conjunction with the drawings and the specific embodiments the utility model is described further:
As shown in drawings, the high temperature resistant Nomex of PPS fiber ladder degree of the present utility model is layer structure, it comprises middle base cloth 1, the PPS mixed fiber layer 3 that sticks on the PPS fibrage 2 of base cloth 1 upper surface and stick on base cloth 1 lower surface, and the upper surface of described PPS fibrage 2 also is pasted with PPS superfine fibre layer 4 by needing machine acupuncture and is used as surface layer; Described base cloth 1 is weaved cotton cloth for the PPS fibre machine; Described PPS mixed fiber layer 3 is mixed by the PPS fiber of two kinds of different-diameters.
Wherein, described PPS fibrage and PPS mixed fiber layer stick on the base cloth by needing machine acupuncture.
In sum, by adopting PPS superfine fibre layer 4 as the surface layer of Nomex, reach the holes of products gauge structure and become graded, stop fine particle when making flue gas by surface layer, realize top layer and deep layer combined filtering, filter effect is strong.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
