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.
摘要:
A tile using an activated carbon, which is excellent as a formaldehyde absorbent, and a preparation process thereof are disclosed. The effect of activated carbon on absorbing formaldehyde is maximized by the activated carbon-in-core structure, in which the problem of activated carbon that is easily oxidized during a heat treatment may be overcome.
摘要:
A ceramic filter and method for preparing the same. The method for preparing the ceramic filter according to the present invention is characterized in comprising the steps of: (a) coating firstly a ceramic green paper prepared by using a slurry solution comprising ceramic fiber of 0.1-10 mm length, with an aluminum silicate solution and drying the firstly coated paper; (b) coating secondly the dried ceramic green paper with an aluminum phosphate solution and drying the secondly coated paper; and (c) calcining the dried ceramic green paper obtained from the step (b). The ceramic filter according to the present invention has excellent mechanical strength since the bonding strength between ceramic fibers is very high, and shows good porosity, gas permeability, and efficiency for capturing microparticles since the pores between the ceramic fibers are less blocked, and thus can be very usefully applied to gas exhaustion system for automobile.
摘要:
The present invention relates to a vacuum insulation material including an inner bag and to a method for manufacturing same. The method for manufacturing the vacuum insulation material includes: a step of manufacturing a core material; a step of compressing and packing the entire surface of the core material using an inner bag made of a breathable film material; a step of disposing a getter on the upper portion of the inner bag; and a step of vacuum-packing a covering material on the upper portion of the inner bag. The inner bag is made of polypropylene (PP), polyester (PET), and/or polyethylene. Since the inner bag is manufactured using a breathable film having fine holes, the method for manufacturing the vacuum insulation material may have improved efficiency, and the vacuum insulation material may be improved in terms of the long-term durability and vacuum insulation properties thereof.
