Abstract
The utility model relates to a filter felt of a fiberglass-bulk weaving coating. The upper surface and the lower surface of the fiberglass-bulk weaving fabric are coated with a layer of polytetrafluoroethylene film respectively. The filter felt has the advantages of resisting high temperature, thus being mainly applied to the environments with the high temperature of 260 to 300 DEG C; the instant usage temperature is 300 DEG C; the filter felt has good dimension stability, high tensile breaking strength, strong acid-alkali resistance, oxidation resistance, wearability and flexural resistance, and is long in service life, and good in air-breathing performance between the coated product and the normal treatment product and high in filtering precision, and improves the filtering wind speed of the dedusting surface.
Description
Technical field
The utility model relates to a kind of filter felt, the Woven coated filter felt of particularly a kind of glass fiber bulk strand.
Background technology
At present, at the filter felt that industrial and minerals such as incinerator, steel industry, carbon black, coal-burning boiler use, the heat-resisting quantity of product is poor, and filter efficiency is low, and chemical resistance is poor.
The utility model content
The utility model is to provide a kind of glass fiber bulk strand high temperature resistant, that filter efficiency is high Woven coated filter felt.
In order to solve above technical problem, the utility model provides a kind of glass fiber bulk strand Woven coated filter felt, at upper and lower one deck polytetrafluoroethylene (PTFE) overlay film that respectively scribbles of the woven cloth of glass fiber bulk strand.
Superior effect of the present utility model is:
1) high temperature resistant, be mainly used in the occasion of 260 ℃～300 ℃ of high temperature, moment serviceability temperature be 300 ℃;
2) dimensional stability is good, the tensile break strength height;
3) have reason strong antiacid alkali, antioxygenic property, wear-resisting folding resistance, long service life;
4) permeability is between overlay film product and conventional treatment properties of product, and the filtering accuracy height, improved the filtration velocity of dedusting face.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The number in the figure explanation
The woven cloth of 1-glass fiber bulk strand; 2-polytetrafluoroethylene (PTFE) overlay film.
The specific embodiment
See also shown in the accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of glass fiber bulk strand Woven coated filter felt, at the upper and lower one deck polytetrafluoroethylene (PTFE) overlay film 2 that respectively scribbles of the woven cloth 1 of glass fiber bulk strand.
Drop in the steel industry blast furnace gas the utility model on probation, through experiment confirm, continuous operation temperature of the present utility model is 260 ℃, moment, operating temperature was 300 ℃, warp-wise brute force 〉=2800N/5 * 20cm, broadwise brute force 〉=2500N/5 * 20cm, warp-wise elongation at break≤10%, broadwise elongation at break≤10%, air permeability are 4～6m
