Abstract
The utility model provides a high silica fiber high temperature resisting woven filter felt, which adopts a laminated structure, wherein, high silica fiber layers are glued to the upper and the lowersurfaces of a base cloth, and a vermiculite coating is applied to the upper surfaces of the high silica fiber layers. The utility model has the following advantages: because of good high-temperature resistance, the filter felt is suitable for being used under ultra-high temperatures ranging from 500 to 750 DEG C and remains serviceable at an instantaneous temperature of 900 DEG C; the filter felthas the advantages of good dimensional stability and high tension failure strength; the filter felt is resistant to acid and alkali, and is immune from ageing and degeneration; and the product has anastatic three-dimensional structure, with the internal structure of the fiber layers stretching in a zigzag manner, small void size and high void ratio.
Description
Technical field
The utility model relates to a kind of filter felt, the high temperature resistant needled filtering felt of particularly a kind of high silica fiber.
Background technology
Be used for the filter felt of iron and steel, non-ferrous metal processing, chemical field at present, its serviceability temperature is low, and resistance to elevated temperatures is poor, poor corrosion resistance, and dimensional stability is low.
The utility model content
The utility model is to provide a kind of resistance to elevated temperatures good, corrosion resistance and good, the high temperature resistant needled filtering felt of the high silica fiber of good stability.
In order to solve above technical problem, the utility model provides a kind of high silica fiber high temperature resistant needled filtering felt, this filter felt is a layer structure, pastes the high silica fiber layer on the upper and lower surface of base cloth, is coated with a vermiculite coating at the upper surface of high silica fiber layer.
