Abstract
A HBT needle filtration felt; the upper and the lower faces of a base fabric are symmetrically stuck with synthetic fiber layers and the base fabric is a fiberglass one. The synthetic fiber layer is made by mixing the fiberglass and the PTFE short fiber. The utility model has the advantages that the utility model is high-temperature resistant and the use temperature is about 260 DEG C; the utility model has strong acid and alkali resistance and is corrosion resistant; the anti-oxidation property is good; the breaking strength is high and the abrasion resistance and the friction resistance are good; the filtration rate is high and the service life is long.
Description
Technical field
The utility model relates to a kind of filter felt, particularly a kind of HBT (Hua Bote) needled filtering felt.
Background technology
General filter felt can anti-temperature below 150 ℃, but the occasion higher to temperature, as: the occasion of heatproof such as incinerator, coal-burning boiler, station boiler and oxytolerant, then resistance to elevated temperatures and the antioxygenic property to filter felt has higher requirement.
Summary of the invention
Technical problem of the present utility model is that the HBT that a kind of energy is high temperature resistant and antioxygenic property is good (Hua Bote) will be provided needled filtering felt.
In order to solve above technical problem, the utility model provides a kind of HBT (Hua Bote) needled filtering felt, and it is to paste mixed fiber layer in the top and bottom of base cloth symmetry.
Described base cloth, it is the glass base cloth.
Described fibrage, it mixes for glass fibre and PTFE short fiber.
Superior effect of the present utility model is:
1) high temperature resistant, serviceability temperature is about 260 ℃;
2) acidproof, alkali resistance is strong, and is anticorrosive;
3) oxidative resistance is good;
4) the ultimate strength height, wear-resistant, abrasion resistance good;
5) filter efficiency height, long service life.
Description of drawings
Figure is a structural representation of the present utility model;
The number in the figure explanation
The 1-base cloth; The 2-mixed fiber layer.
The specific embodiment
See also shown in the accompanying drawing, the utility model will be further described.
Shown in accompanying drawing structural representation of the present utility model, the utility model provides a kind of HBT (Hua Bote) needled filtering felt, it is to paste mixed fiber layer 2 in the top and bottom of base cloth 1 symmetry, described base cloth 1 is the glass base cloth, and described mixed fiber layer 2 mixes for glass fibre and PTFE short fiber.
Glass fibre and PTFE short fiber composite acupuncture filter felt are called HBT (Hua Bote) needled filtering felt.
It is on probation that the utility model drops into power plant, through experiment confirm, and 240 ℃ of continuous operation temperature of the present utility model, moment, operating temperature was 260 ℃, brute force 〉=1800n radially, broadwise brute force 〉=1800n, radial fragmentation percentage elongation≤10, broadwise elongation at break≤10, air permeability is 10/m
3～15/m
