Abstract
The utility model discloses an acrylic and polyester composite needle-punched filtering material which comprises a middle layer, wherein an upper mixed face layer is arranged above the middle layer, a lower mixed face layer is arranged below the middle layer, and an outer layer is arranged on the upper mixed face layer. Compared with the prior art, the acrylic/polyester composite needle-punched filtering material has the advantages of high temperature resistance, wear resistance, corrosion resistance, high strength and good air permeability.
Description
[technical field]
The utility model relates to a kind of acrylic and terylene composite acupuncture filtrate.
[background technology]
At present, there is the occasion of requirements at the higher level in cement plant, steel plant, power plant, chemical plant etc. to acidproof, the alkali resistance of filtrate, but existing filtrate is because filtering accuracy is lower, corrosion resistance a little less than, the gas permeability deficiency can't satisfy production operation demand now.
[utility model content]
The utility model is in order to solve above-mentioned deficiency, provides that a kind of filtering accuracy height, decay resistance are strong, the acrylic and the terylene composite acupuncture filtrate of good permeability.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of acrylic and terylene composite acupuncture filtrate, comprised the intermediate layer, it is characterized in that: top, described intermediate layer is provided with mixes surface layer, be arranged with in described intermediate layer and mix surface layer, mix surface layer on described to be provided with skin.
Described intermediate layer is the woven layer of cloth of polyester filament.
The described mixing surface layer of going up constitutes by terylene and acrylic fiber with the following surface layer that mixes.
Described skin constitutes for the acrylic fiber.
The utility model advantage compared with prior art is:
1, heatproof: middle normal temperature sack cleaner filtrate, processing temperature is 130 ℃, moment serviceability temperature be 160 ℃.
2, wear-resisting, corrosion-resistant: as to have that good anti-wear performance, acid-alkali-corrosive-resisting are good, hydrolytic resistance can obviously improve.
3, intensity is big: dimensional stability is good, and wearability is good, tensile break strength height, warp-wise ultimate strength more than or equal to 1100N/5CM*20cm, broadwise ultimate strength more than or equal to 1500N/5CM*20cm, long service life.
4, good permeability: air permeability reaches 20m
3/ m
2.min200pa (12.5m
3/ m
2.min127pa), filtration resistance is steady.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, the 1-intermediate layer; The last mixing of 2-surface layer; 3-mixes surface layer down; The 4-skin.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of acrylic and terylene composite acupuncture filtrate have comprised intermediate layer 1, it is characterized in that: 1 top, described intermediate layer is provided with mixes surface layer 2, be arranged with in described intermediate layer 1 and mix surface layer 3, mix surface layer 2 on described to be provided with outer 4.
Described intermediate layer 1 is the woven layer of cloth of polyester filament, and the described mixing surface layer 2 of going up constitutes by terylene and acrylic fiber with the following surface layer 3 that mixes, and described outer 4 is acrylic fiber formation.
The utility model drops in the steel plant on probation, through experiment confirm, 130 ℃ of the continuous operation temperature of this product, moment operating temperature be 160 ℃; Warp-wise ultimate strength 〉=1100N/5 * 20cm, broadwise ultimate strength 〉=1500N/5 * 20cm; Warp-wise elongation at break≤30%, broadwise elongation at break≤50%; Air permeability is 20m3/m2.min200pa.Anti-oxidant, hydrolytic resistance energy of the present utility model, anti-wear performance height; The long service life of product.
Claims (4)
