Inorganic fiber sheet, honeycomb molded body and honeycomb filter

Abstract

The inorganic fiber sheet contains glass fibers as a main component, while containing 3-20% by mass of organic fibers relative to the total mass of the inorganic fiber sheet, the organic fibers havingaspect ratios of 300 to 2000.

Description

technical field

[0001] The invention relates to an inorganic fiber sheet, a honeycomb shaped body and a honeycomb filter.

[0002] This application claims priority based on Japanese Patent Application No. 2016-207709 for which it applied in Japan on October 24, 2016, and uses the content here. Background technique

[0003] Since ceramic fibers have characteristics such as high heat resistance, high heat insulation, and non-combustibility, 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 cushioning materials, heat-resistant shielding materials, separators, and catalysts. Furthermore, the formed honeycomb body obtained by corrugating the inorganic fiber sheet is used as a honeycomb filter for heat exchange or a honeycomb filter for gas adsorption carrying a functional material such as an adsorbent.
