Abstract
The utility model relates to a glass fiber and basalt fiber composite heat-resistant filter felt, wherein a layer of glass fiber and basalt fiber synthetic fabric layer is respectively bonded on the upper surface and the lower surface of glass fiber base fabric, and a polytetrafluoroethylene (PTFE) film-coating layer is covered on the glass fiber and basalt fiber synthetic fabric layer at the dust-facing surface. The filter felt has the advantage of high temperature resistance, the using temperature is 300 degrees, the instant use temperature is 350 degrees; and the filter felt has the spark-prevention performance, and good heat-resistant performance as well as long service life.
Description
Technical field
The utility model relates to a kind of filter felt, particularly a kind of glass fibre and basalt fibre complex fire resistant filter felt.
Background technology
At present, at the filter felt that power plant, chemical industry, metallurgy industry use, the heat-resisting quantity of product is poor, and fire line is poor, and service life is short.
The utility model content
The utility model is that a kind of high temperature resistant, glass fibre and basalt fibre complex fire resistant filter felt that fire protecting performance is good will be provided.
In order to solve above technical problem, the utility model provides a kind of glass fibre and basalt fibre complex fire resistant filter felt, at the upper and lower layer of glass and the basalt fibre mixed fiber layer of respectively being stained with of glass fibre base cloth, on the glass fibre of dust-collecting face and basalt fibre mixed fiber layer, be coated with polytetrafluoroethylene PTFE plated film layer.
Described glass fibre and basalt fibre mixed fiber layer, wherein the ratio of glass fibre and basalt fibre is 55: 45.
Superior effect of the present utility model is:
1) high temperature resistant, 300 ℃ of serviceability temperatures, moment serviceability temperature be 350 ℃;
2) have the performance of anti-" Mars ", heat resistance is good;
3) long service life.
