Problems solved by technology

[0003] The disadvantage of the fiber mat made of this binder is that the fiber mat itself has poor foldability and cannot be bent and folded at will. The product is inconvenient to be bent, wound and wrapped during the construction process. Elasticity can easily lead to poor sealing performance, fire leakage, air leakag

Example Embodiment

[0020] 1. Pulp preparation: add 55 kg of ceramic fiber, 15 kg of low-melting PET fiber, 8 kg of organic binder and 5 kg of additives into the water and stir evenly, stirring for 10-20 minutes;

[0021] 2. Deslagging: Use deslagging equipment to remove the particle size in the slurry> 45um slag ball;

[0022] 3. Forming: The forming thickness of the fiber felt blank is controlled at 13mm~14mm; the mesh belt speed is 0.4~0.6m / min.

[0023] 4. Vacuum suction filtration: Process operation requirements: vacuum degree ≥0.02Mpa, to remove most of the moisture in the wet felt.

[0024] 5. Drying: Use electric heating equipment to dry the felt blanks, and the drying temperature is controlled at 110℃~170℃.

[0025] 6. Processing: Use a cutting machine to cut the felt into products of various shapes and specifications required by customers.

[0026] Compared with ordinary fiber felt performance index:

[0027] Ordinary fiber felt foldability: 900 (20mm) above 20mm, no product, flexibility: can not b...

Abstract

The invention relates to an elastic fiber felt and a preparation method thereof. The elastic fiber felt is characterized in that the elastic fiber felt is composed of ceramic fiber, low-melting-point PET fiber, an organic binding agent and an additive. The elastic fiber felt comprises, by weight, 35-75% of ceramic fiber, 15-25% of low-melting-point PET fiber, 1-10% of the organic binding agent and 1-5% of the additive. The fiber felt provided by the invention has good flexibility, and can be freely folded and bent on any direction. When the fiber felt is used in a construction process, the felt can be used for freely wrapping and winding along with the shapes of equipment and parts. Under normal temperature, the resilience rate of the product reaches 100%. The felt can be processed into sealing materials or other irregular-shaped products with different shapes. The product has excellent flexibility and resilience. The fiber felt has good elasticity. When the fiber felt is used as a sealing material, the sealing effect is better ensured with the excellent resilience.

Description

technical field [0001] The invention relates to the field of filter materials, in particular to an elastic fiber felt and a preparation method. Background technique [0002] At present, the binders added in the production of ordinary fiber mats generally use silica gel and starch, and the production process is mostly: 1. Pulp preparation: mix ceramic fibers, silica gel and starch in a certain proportion to make felt pulp 2. Forming: use the mold to vacuum filter the wet fiber felt blank; 3. Drying: use hot air or electric heating to remove the moisture in the fiber felt wet blank; 4. Processing: use cutting equipment to dry the dried fiber felt The fiber mat is processed into products of various specifications and sizes required; [0003] The disadvantage of the fiber mat made of this binder is that the fiber mat itself has poor foldability and cannot be bent and folded at will. The product is inconvenient to be bent, wound and wrapped during the construction process. Elas...
