The present invention relates to a sound absorbing sheet having excellent sound absorbing performance and surface decorative effects. The sound absorbing sheet of the present invention is characterized by comprising a base and having an average sound absorption of 0.4 or higher in a frequency range of 200 to 2000 Hz. The permeability and air porosity of a base layer of the sound absorbing sheet of the present invention may be adjusted, thereby achieving significantly superior effects of sound absorbing performance despite the thinness of the sound absorbing sheet.

The present invention relates to a porous ceramic structure, and a dehumidification/humidification apparatus comprising the same. More particularly, the present invention comprises: a porous ceramic humidifying medium having an inner circumferential surface and an outer circumferential surface; a dehumidifying medium which has an inner circumferential surface and an outer circumferential surface, and which is disposed in the porous ceramic humidifying medium; and a cutoff layer formed between the inner circumferential surface of the humidifying medium and the outer circumferential surface of the dehumidifying medium. The porous ceramic structure and the dehumidification/humidification apparatus comprising same according to the present invention can easily increase the humidifying and dehumidifying capacity, simplify a flow channel, and achieve a compact design.
摘要:
The present invention relates to a catalyst including a ceramic structure containing porous ceramic paper and a catalyst component supported on the ceramic structure, and to a method for removing formaldehyde using the catalyst. The present invention provides a catalyst in which a structure made of ceramic paper having excellent characteristics in terms of porosity, specific surface area, and the like is used as a support for the catalyst component to maximize an effective area for reacting the supported catalyst component with a substance to be treated, thereby improving catalyst performance. The present invention also provides a method of using the catalyst.
