Abstract
The utility model provides a fuel composite filter paper, which comprises a first protective layer, a first filter layer, a second protective layer and a shaping layer, wherein the first protective layer is coated on one side of the first filter layer, the second filter layer is coated on the other side of the first filter layer, the second protective layer is coated on one side of the second filter layer away from the first filter layer, the shaping layer is arranged on one side of the second protective layer away from the second filter layer, and the service life of the composite filter paper can be prolonged by arranging a melt-blown cloth layer; the surface fuzzing of the melt-blown fabric layer and the glass fiber layer can be prevented by arranging the spun-bonded non-woven fabric layer; through setting up the glass fiber layer, can improve filter accuracy, through setting up the wire netting protective layer, for compound filter paper setting.
Description
Technical Field
The invention relates to filter paper, in particular to fuel composite filter paper.
Background
The fuel oil is generally refined by crude oil through a complex process and is finally conveyed into the oil tank, in the process, impurities in the fuel oil inevitably enter the oil tank, the fuel oil needs to be filtered by using filter paper, most of the existing fuel oil filter paper is single-layer filter paper made of wood pulp fibers, the filter precision is low, and therefore the research of the composite filter paper with high filter precision is urgent.
Disclosure of Invention
The utility model provides a compound filter paper of fuel solves the low problem of filter paper filter fineness.
The technical proposal of the utility model for solving the technical problem is that: the utility model provides a compound filter paper of fuel, includes first inoxidizing coating, first filter layer, second inoxidizing coating and shaping layer, first inoxidizing coating coats in one side of first filter layer, the second filter layer coats in the opposite side of first filter layer, the second inoxidizing coating coat in one side of first filter layer is kept away from to the second filter layer, the shaping layer sets up in one side that the second filter layer was kept away from to the second inoxidizing coating.
The first protective layer is a spunbonded non-woven fabric layer.
The first filter layer is a melt-blown cloth layer.
The second filter layer is a glass fiber layer.
The second protective layer is a spun-bonded non-woven fabric layer.
The shaping layer is a net structure woven by iron wires.
The invention has the beneficial effects that: the melt-blown cloth layer is arranged, so that the service life of the composite filter paper can be prolonged; the surface fuzzing of the melt-blown fabric layer and the glass fiber layer can be prevented by arranging the spun-bonded non-woven fabric layer; through setting up the glass fiber layer, can improve composite filter paper's filter fineness, through setting up the network structure that the wire netting was woven, for composite filter paper setting.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Reference numerals are as follows: 1. a first protective layer; 2. a first filter layer; 3. a second filter layer; 4. a second protective layer; 5. a shaping layer.
Detailed Description
The invention is further illustrated below with reference to the figures and examples.
In fig. 1, the fuel composite filter paper is composed of a plurality of different layered structures, including a first protective layer, a first filter layer, a second protective layer, and a shaping layer.
The first filter layer is a melt-blown cloth layer, the fineness of fibers of the melt-blown cloth layer is 0.5-1.0 μm, and the fibers are randomly distributed to provide more heat bonding opportunities among the fibers, so that the melt-blown filter material has larger specific surface area, higher porosity and higher dust holding capacity, and the service life of the composite filter paper can be prolonged, the first protective layer is coated on the outer side of the first filter layer, the first protective layer is a spun-bonded non-woven cloth layer and can effectively prevent the outer surface of the melt-blown cloth layer from fluffing, the second filter layer is coated on the inner side of the melt-blown cloth layer and is a glass fiber layer, the pores of the glass fibers are smaller than those of the melt-blown cloth layer, the filter precision of the filter paper is higher compared with that of other materials under the same resistance condition, the filter paper can be filtered again through oil of the melt-blown cloth layer, and the filter precision of the composite filter paper can be improved to a great extent, the second inoxidizing coating coat in the inboard of second filter layer, the second inoxidizing coating with the material of first inoxidizing coating is the same, can prevent that the internal surface of second filter layer from producing the fluff phenomenon, the shaping layer sets up the inboard at compound filter paper, the shaping layer is the netted material that the iron wire was woven, can set compound filter paper.
