Abstract
The utility model relates to a teron high strength and low extension needled filter felt. The upper surface and the lower surface of teron high strength and low extension base cloth are respectively compounded with a layer of polyester fiber by a needle machine. The utility model has the advantages of high breaking strength, short breaking extension, low percent of thermal shrinkage, favorable shock resistance, improved pressure resistance, long service life and temperature, acid and alkali resistance.
Description
Technical field
The utility model relates to a kind of needled filtering felt, particularly a kind of high-tenacity terylene flatness type needled filtering felt.
Background technology
At present, at the filter felt that steel plant, cement plant, mine, non-ferrous metals smelting works use, the ultimate strength of product is poor, and percent thermal shrinkage is big, and impact resistance is poor, and service life is short.
The utility model content
Technical problem of the present utility model is to provide a kind of long service life, shock resistance good, and the high high-tenacity terylene flatness type needled filtering felt of ultimate strength.
In order to solve above technical problem, the utility model provides a kind of high-tenacity terylene flatness type needled filtering felt, on the upper and lower surface of the low elongation of high-tenacity terylene degree base cloth, with the compound one deck polyster fibre of needing machine difference.
Superior effect of the present utility model is:
1) ultimate strength height, extension at break is little, and percent thermal shrinkage is little;
2) shock resistance is good, and withstand voltage level improves, long service life;
3) heatproof is suitable for, acidproof, alkaline-resisting being suitable for.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The number in the figure explanation
1-polyster fibre; 2-base cloth.
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 high-tenacity terylene flatness type needled filtering felt, on the upper and lower surface of the low elongation of high-tenacity terylene degree base cloth 2, with the compound one deck polyster fibre 1 of needing machine difference.The polyster fibre 1 on upper and lower surface is the same or inequality.
The utility model is dropped into the cement plant to be tried out, through experiment confirm, continuous operation temperature of the present utility model is 130 ℃, moment, operating temperature was 150 ℃, warp-wise brute force 〉=1800N/5 * 20cm, broadwise brute force 〉=1800N/5 * 20cm, warp-wise elongation at break≤15%, broadwise elongation at break≤30%, air permeability are 12m
3/ m
2.min, percent thermal shrinkage≤0.5%.
