Abstract:
The invention relates to a system and method for continuous production of ceramic non-wovens, essentially comprising a mixing device for the production of a suspension consisting of ceramic powder, aqueous aminoxide and cellulose. The suspension is produced in batches or in a continuous manner and can occur in one or several steps by adding all components or the individual components thereof. The invention also comprises a device for concentrating the solution made of ceramic powder, aqueous aminoxide and cellulose thus produced. The mixture is sheered in an intensively mixed heated state in said device and transported with the evaporation of water until a precisely defined amount of water is evaporated an a suspension of ceramic powder in a deformable solution of cellulose in aqueous aminoxide is obtained. The invention also comprises a device which is connected to the above-mentioned concentration device and which is used to process the deformable ceramic cellulose suspension to form ceramic green fibers. Said device enables ceramic green fibers to be formed and, optionally, a green fiber non-woven. A system can also be integrated, enabling the green fiber non-woven to be pyrolyzed and sintered or a non-woven made of ceramic green fibers to be pyrolyzed and sintered. The ceramic non-wovens thus obtained can be used in the chemical, power-generating, recycling and motor industry, in biotechnology and in medicine. Said non-wovens can also be used in catalyzer technology for use as catalyzers for internal combustion engines or in chemical reactors.
