Abstract
A glass fiber composite corrosion-resistant needle punched filter felt relates to a filter felt special for lime kiln industries. An upper fur net layer is arranged above a base cloth layer, a lower fur net layer is arranged under the base cloth layer, and a poly tetra fluoro ethylene (PTFE) steeping coating layer is covered on the outer side of the upper fur net layer and the outer side of the lower fur net layer. The base cloth layer adopts alkali-free glass fiber spinning woven fabrics, and the upper fur net layer and the lower fur net layer are made by mixing 10-percent PTFE fibers and alkali-free glass fibers with added zirconium oxide of a certain proportion. The glass fiber composite corrosion-resistant needle punched filter felt is corrosion-resistant, high-temperature-resistant, good in air permeability, high in longitudinal intensity and latitudinal intensity and small in elongation rate. The cost performance of the glass fiber composite corrosion-resistant needle punched filter felt is recognized by consuming enterprises, and the service life is prolonged by approximately one time.
Description
Technical field:
The utility model relates to the filter felt of a kind of limekiln industry special use, is specifically related to a kind of glass fibre composite anticorrosive needled filtering felt,
Background technology:
Domestic similar industry is all at a large amount of development and application bag type dust removing technologies at present, aspect the acupuncture filtering material, the multiple material of forward, multiple processing mode direction develops, the needled filtering felt of existing limekiln sector application roughly has, and the one, the felt body that the PTFE fiber is made, but the cost height of this product, enterprise is difficult to bear, the 2nd, the P84 product, its cost an arm and a leg and resistance to acids and bases general, the 3rd, PPS felt body, though price can, but its heatproof can only remain on below 190 °, do not satisfy the working condition requirement of limekiln industry, and the Acidity of Aikalinity proportion of the sector is higher, its pH value between 2-14.
Hence one can see that, and existing limekiln industry filtering material at first will be considered its production cost, is its practicality then, and promptly entreprise cost reduces, and discharge standard is up to standard to be the research and development key of this project.
The utility model content:
The purpose of this utility model provides a kind of glass fibre composite anticorrosive needled filtering felt, and its corrosion-resistant and high-temperature resistant, permeability are good, and through broadwise intensity height, percentage elongation is little, and the cost-effectivenes price ratio obtains the approval of user enterprise, and improves nearly one times service life.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises base cloth layer 1, upward fleece layer 2-1, following fleece layer 2-2, PTFE flood clad 3, last fleece layer 2-1 is arranged on the top of base cloth layer 1, following fleece layer 2-2 is arranged on the below of base cloth layer 1, the be incumbent on outside of fleece layer 2-1 and following fleece layer 2-2 of PTFE dipping clad 3.
The utlity model has following beneficial effect: corrosion-resistant and high-temperature resistant, permeability are good, and through broadwise intensity height, percentage elongation is little, and the cost-effectivenes price ratio obtains the approval of user enterprise, and improves nearly one times service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the contrast schematic diagram of the utility model and other filtering products.
The specific embodiment:
Referring to Fig. 1-2, this specific embodiment is by the following technical solutions: it comprises base cloth layer 1, goes up fleece layer 2-1, fleece layer 2-2, PTFE dipping clad 3 down, last fleece layer 2-1 is arranged on the top of base cloth layer 1, following fleece layer 2-2 is arranged on the below of base cloth layer 1, the be incumbent on outside of fleece layer 2-1 and following fleece layer 2-2 of PTFE dipping clad 3.
Described base cloth layer 1 adopts alkali-free glass fibre to spin cotton and weave cloth;
The described fleece layer 2-1 that go up mixed by the PTFE fiber that has added the zirconic alkali-free glass fibre of certain proportion and 10% with following fleece layer 2-2.
Its production technology circuit is:
The described certain proportion zirconia that added; NaOH and glass fibre that limekiln chance water is generated are met the NaOH reaction generation zirconia that water generates; form a kind of colloid diaphragm; its attached being coated on the filter material surface; can effectively stop the erosion of acid-base solution, thereby play the effect of protection filtrate glass.
Described dipping typing adopts the dipping method of PTFE liquid to handle; the felt body is made further parcel makes felt body inside and surface be completed into diaphragm behind high-temperature shaping; and then play the effect of dual fail-safe, the effect that reaches resist chemical has increased the purpose that fine dust is collected again.
This specific embodiment is to form by carrying out acupuncture; after compound; guaranteed the winding of felt body and base cloth; promptly strengthened felt body intensity; make the physicochemical property of two kinds of fibers be able to abundant complementation again; reduce and reduced risk because of chemical attack; the stratiform that adopts is compounded to form three-dimensional structure; guaranteed the winding of felt body and base cloth; increased brute force, the dipping of the emulsion of back arrangement PTFE has been realized the second protection to the fibrofelt body; strengthened the ability of its high-temperature-resistant and anti-corrosion, and Pm2.5 and following fine dust have been realized filtering and the effect of separating.
This specific embodiment corrosion-resistant and high-temperature resistant, permeability are good, and through broadwise intensity height, percentage elongation is little, and the cost-effectivenes price ratio obtains the approval of user enterprise, and improves nearly one times service life.
