Abstract
The utility model discloses a composite high-temperature-resistant needled-punched felt consisting of basalt fiber and P84 fiber. The needled-punched felt has a laminar structure; and alkali-free basalt and P84 composite fiber layers are symmetrically bonded on the upper and lower surfaces of basalt base cloth respectively. The needled-punched felt has the advantages of high temperature resistance, service temperature of 120-260 DEG C and momentary service temperature of up to 300 DEG C; and the resistance of a filter material is reduced, the service temperature is raised, and the service life is prolonged.
Description
Technical field
The utility model relates to fiber needled felt; Particularly a kind of basalt fibre and P84 polyimide fiber complex fire resistant Nomex; This material can be used for aspects such as clarifying smoke material collection and equipment protection, can also be used for the technical field of liquid-solid separation and gas solid separation.
Background technology
At present, higher in the flue-gas temperature of industries such as iron and steel, metallurgy, cement, electric power, chemical industry, pharmacy, and etchant gas content is bigger, common fiber needled felt is difficult to satisfy its high-temperature particle thing to the calcination of filter bag and the corrosive gas destruction to filtrate.
The utility model content
The technical problem of the utility model provides a kind of serviceability temperature height, good basalt fibre and the high temperature resistant Nomex of P84 fiber composite of resist chemical performance.
In order to solve above technical problem, the utility model provides a kind of basalt fibre and the high temperature resistant Nomex of P84 fiber composite, and this Nomex is a layer structure, and at the upper and lower surfaces of basalt base cloth, symmetry is pasted composite fibre layer respectively.
Described basalt base cloth is a kind of continuous basalt yarn fabric.
Described composite fibre layer is alkali-free basalt and P84 composite fibre layer.
The superior effect of the utility model:
1) high temperature resistant, serviceability temperature is 120-260 ℃, moment serviceability temperature can reach 300 ℃.；
2) reduce the resistance of filtrate, improved serviceability temperature and life-span.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Label declaration among the figure:
1-alkali-free basalt and P84 composite fibre layer; 2-basalt base cloth.
The specific embodiment
Below in conjunction with Fig. 1 and specific embodiment the utility model is at length explained.
The utility model provides a kind of basalt fibre and the high temperature resistant Nomex of P84 fiber composite, and this Nomex is a layer structure, and the two sides symmetry of basalt base cloth 2 is pasted basalt and the compound fibrage 1 of P84.
Described basalt base cloth 2 is fabrics that a kind of continuous basalt yarn adopts the plain weave weave to process.
Basalt base cloth 2 provides good intensity for Nomex; Fibrous face layer adopts basalt and P84 composite fibre layer 1; Because the special trilobal cross structure of its P84 polyimides; Make the most of dust of dust be trapped within the surface of Nomex, reduced the resistance of filtrate, the service life of having improved filtrate.
The utility model is dropped into actual operating mode use, through implementing proof, the continuous operation temperature of the utility model is 120 ℃ ~ 260 ℃; Moment, serviceability temperature was 300 ℃; Brute force>=1800N/5 * 20 ㎝ radially, broadwise brute force>=1800N/5 * 20 ㎝, radial fragmentation percentage elongation≤25%; Broadwise elongation at break≤25%, air permeability 2-6m
3/ m
2Min has improved 10% service life.
