Problems solved by technology

However, it is known that the bond between fibers of the inorganic fiber sheet is weak, and if the amount of the binder component is increased in order to improve it, the corrugation property tends to be impaired.

Embodiment 1

[0094] Add 60 parts by mass of glass fibers (fiber diameter: 6 μm, fiber length: 6 mm) as fiber components, 40 parts by mass of wood pulp (NBKP) beaten to 500 CSF, and 16 parts by mass of Polyvinyl alcohol (manufactured by Kuraray, Poval K-17U6) as a binder, and a small amount of dispersant and defoamer as auxiliary agents were mixed, stirred, and dispersed to prepare a raw material slurry with a concentration of 0.2% by mass. Using the wet papermaking method, form a randomly arranged network, spray acrylic emulsion to make it 0.2g / m 2 and dried to obtain a one-layer glass fiber sheet.

[0095] The mass per unit area of ​​the obtained glass fiber sheet was measured in accordance with JIS P8124, and the mass per unit area was 44 g / m 2 .

Embodiment 2

[0097] A glass fiber sheet was obtained in the same manner as in Example 1 except that the glass fiber was 70 parts by mass and the wood pulp (NBKP) was 30 parts by mass.

Embodiment 3

[0099] Change the mass per unit area to 30g / m 2 , except that, a glass fiber sheet was obtained in the same manner as in Example 1.

Abstract

Provided is a glass fiber sheet for a filter, which has good corrugated moldability and excellent corrugated processing suitability, and which can sufficiently support a functional material such as an adsorbent. A glass fiber sheet for a filter, which is formed by wet papermaking using glass fibers as the main component, further containing wood pulp and a binder, and which exhibits the function of a filter by having a functional material supported therein, 51-85% by mass of all fiber components of the glass fiber sheet are glass fibers, 10-49% by mass of all fiber components of the glass fiber sheet are wood pulp, the content of the binder is 1% by mass or more with respect to the total mass of the glass fiber sheet for filters, and the mass per unit area of the glass fiber sheet is 15-55 g / m2.

Description

technical field [0001] The present invention relates to a glass fiber sheet for a filter, and specifically relates to a glass fiber sheet for a filter used as a filter by loading a functional material therein. Background technique [0002] Ceramic fibers have characteristics such as high heat resistance, high heat insulation, and incombustibility, and therefore, inorganic fiber sheets using ceramic fibers are widely used. For example, the inorganic fiber sheet is used as a support for functional materials such as heat insulating materials, heat-resistant buffer materials, heat-resistant shielding materials, separators, and catalysts. In addition, a honeycomb formed body obtained by corrugating an inorganic fiber sheet is used as a honeycomb filter for heat exchange or a honeycomb filter for gas adsorption on which a functional material such as an adsorbent is supported. [0003] For example, Patent Documents 1 and 2 describe a method for producing an inorganic fiber sheet, ...
