Abstract
A glass fiber and polyimide fiber compound filter spunlace felt is characterized in that glass fiber and P84 compound fiber surface layers are adhered to two surfaces of glass fiber base cloth by means of high-pressure water jet, wherein the glass fiber base cloth is a fabric made of bulked alkali-free glass fiber yarns by means of plain weaving. The glass fiber and polyimide fiber compound filter spunlace felt has the advantages that damage of process to fibers and the base cloth is decreased by the aid of flexible high-pressure water jet, product strength is high, chemical corrosion resistance is excellent, the service life of a filter medium is prolonged, the use temperature of the spunlace felt ranges from 120 DEG C to 260 DEG C, and the instant use temperature of the spunlace felt can reach 300 DEG C.
Description
Technical field
The utility model relates to a kind of glass and glass fibre and polyimide fiber combined filtration water thorn felt, the filter felt that particularly a kind of filtering material that is used for flue gas and treating flour dust is made.
Background technology
At present, at the most of filtering material of the employed filtrate of industries such as iron and steel, metallurgy, cement, electric power, chemical industry, pharmacy is to adopt needling process to make, the water fluid jet reinforce non-weaving cloth is to utilize the impact of the current of high speed and high pressure to fibre web, impel the mutual obvolvent of fiber, realize that reinforcement fiber web is to satisfy the demand of dedusting industry.
The utility model content
For solving the problem of aforementioned existence, the utility model provides a kind of serviceability temperature height, good glass and glass fibre and the polyimide fiber combined filtration water thorn felt of acid-resisting corrosive nature.Its structure is to adopt high-pressure water jet machine, perverse stickup glass of symmetrical water and the compound fibrous face layer of polyimide fiber on the two sides of glass base cloth; Described glass base cloth is the fabric that a kind of varicosity alkali-free glass fiber yarn adopts the plain weave weave to make.
Superior effect of the present utility model is:
1. adopt the flexible high pressure water jet, reduced the damage that technology causes fiber and base cloth;
2. intensity height, brute force 〉=2000N/5 * 20 ㎝ radially, broadwise brute force 〉=2000N/5 * 20 ㎝;
3. acid-resisting corrosive nature excellence;
4. long-term serviceability temperature is 120-260 ℃, moment serviceability temperature can reach 300 ℃.
