Abstract

본 발명은 기존 내화 캐스타블(Castale)의 시공시 접착력과 비중으로 인한 무게 800℃ 이상의 고온에서 결합력과 단열성의 문제점 기존 화이버캐스트(fiber cast)의 자연상태에서 양생이 되지 않고 세라믹화이버 제품을 가공한 모듈(Module), 브랑켓(Blanket)등의 900℃ 이상에서는 급속한 수축과 분진등의 문제점을 동시에 개선한 세라믹화이버(Ceramic fiber)를 이용한 부정형 내화재 조성물에 관한 것이다.The present invention relates to a method for manufacturing a ceramic fiber product that does not cure in a natural state of an existing fiber cast but which has a problem of bonding strength and heat insulation at a high temperature of 800 ° C or more due to adhesive force and specific gravity during casting of a conventional refractory castable The present invention relates to a monolithic refractory composition using a ceramic fiber which simultaneously improves the problems such as rapid shrinkage and dust at a temperature of 900 ° C or higher such as a module, a blanket and the like.

본 발명은 결합력과 단열성을 위하여 세라믹화이버(Ceramic fiber)를 5㎜이하, 5∼10㎜, 10∼20㎜ 세 종류로 절연, 파쇄하여 상부에 명시한 각 중량부 별로 제품 종류에 따라 첨가하여 혼합 혼련하여 제조하게 된다.A ceramic fiber is insulated and crushed to have a diameter of 5 mm or less, 5 to 10 mm or 10 to 20 mm for the bonding force and the heat insulating property, .

본 발명에서 상기 조성물 중 세라믹화이버는 결합력, 내화성능, 단열성을 지니고 기존 캐스타블 보다 1.5∼6배 정도 비중이 낮은 결과를 가져오게 된다. 그리고 여러 종류의 알루미나 시멘트는 고온에서의 고강도와 내화성능을 유지시켜주고 기타 첨가제는 높은 점성을 가지게 하여주어 접착력과 자연상태에서 양생될 수 있는 결과를 가져오게 한다.In the present invention, the ceramic fiber has bonding force, fire resistance, and heat insulating property, and results in a specific gravity of 1.5 to 6 times lower than that of the conventional castable. And various kinds of alumina cement maintains high strength and fire resistance performance at high temperature, and other additives have high viscosity, resulting in adhesion and curing in a natural state.

본 발명은 기존 내화 캐스타블(Catable)의 단열성, 내화도, 접착력, 비중으로 인한 무게, 고온에서의 스폴링(Spalling), 크랙(Crack) 현상등의 문제점을 해결 보완하여 사용자에게 여러 가지 편리함과 경제적 이익을 주고 생산성 향상에 기여하는데 목적을 두고자 하는 것이다.The present invention solves the problems of thermal insulation, refractoriness, adhesive strength, weight due to specific gravity, spalling at high temperature, and cracking of the existing refractory castable (Catable) It is intended to contribute economic benefits and improve productivity.
