Beschreibung
Zusammenfassung:	Disclosed is a manufacturing method capable of increasing adsorption or coating coverage of a titanium dioxide powder on ceramic fibers. The manufacturing method comprises the steps of: putting a liquid mixture in which a TiO_2 powder is mixed with deionized water into a water tank; immersing a ceramic fiber material in the liquid mixture so that a fiber surface of the ceramic fiber material is coated with the TiO_2 powder; and drying and heat treating the ceramic fiber material. In a coating step, ultrasonic vibration is applied to the liquid mixture to coat an inner fiber surface of the ceramic fiber material with the TiO_2 powder. Accordingly, a high temperature ceramic fiber product with excellent insulation properties and low costs can be provided. 세라믹 파이버에 이산화티타늄 분말의 흡착 또는 코팅 커버리지(Coverage)를 증가시킬 수 있는 제조 방법이 개시된다. 상기 방법은, TiO2 분말을 탈이온수에 혼합한 액상 혼합물을 수조에 넣는 단계; 상기 액상 혼합물에 세라믹 파이버 재료를 담가 상기 TiO2 분말이 상기 세라믹 파이버 재료의 파이버 표면에 코팅되도록 하는 단계; 및 상기 세라믹 파이버 재료를 건조하고 열처리하는 단계를 포함하며, 상기 코팅 단계에서 상기 액상 혼합물에 초음파 진동을 인가하여 상기 TiO2 분말이 상기 세라믹 파이버 재료 내부 파이버 표면에 코팅되도록 한다.
