Title (EN) METHOD FOR PRODUCING SYNTHETIC HECTORITE AT LOW TEMPERATURE AND UNDER ATMOSPHERIC PRESSURE
(FR) MÉTHODE DE PRODUCTION D'HECTORITE SYNTHÉTIQUE À BASSE TEMPÉRATURE ET SOUS PRESSION ATMOSPHÉRIQUE
(KO) 합성-헥토라이트의 저온 상압 제조방법
Abstract:
(EN) The present invention relates to a method for producing synthetic hectorite at a low temperature and under atmospheric pressure and synthetic hectorite produced thereby and, more specifically, provides a method for producing synthetic hectorite and synthetic hectorite produced thereby, wherein the method introduces a step of forming an Li-Mg precipitate and particularly uses a weak base catalyst when forming the Li-Mg precipitate, thereby producing synthetic hectorite which can go through a crystallization reaction under the conditions of a low temperature/atmospheric pressure and reduce the reaction time and has excellent major application properties, and controls the composition ratio of reactants, thereby facilitating the control of the properties.
(FR) La présente invention concerne une méthode de production d'hectorite synthétique à basse température et sous pression atmosphérique et l'hectorite synthétique produite par cette méthode et, plus particulièrement, fournit une méthode de production d'hectorite synthétique et une hectorite synthétique produite par cette méthode, la méthode prévoyant une étape de formation d'un précipité de Li-Mg et utilise en particulier un catalyseur de base faible lors de la formation du précipité de Li-Mg, ce qui permet de produire de l'hectorite synthétique qui peut passer par une réaction de cristallisation dans des conditions de basse température/pression atmosphérique et de réduire le temps de réaction et qui présente d'excellentes propriétés d'application principale, et contrôle le rapport de composition de réactifs, ce qui facilite le contrôle des propriétés.
(KO) 본 발명은 합성 헥토라이트의 저온 상압 제조방법 및 이에 의해 제조된 합성 헥토라이트에 관한 것으로서, 보다 상세하게는 Li-Mg 침전물을 형성하는 단계를 도입하고, 특히 상기 Li-Mg 침전물 형성 시 약염기 촉매를 사용함으로써, 저온/상압의 조건 하에서 결정화 반응이 가능하고, 반응 시간을 단축할 수 있으며, 주요 응용 물성이 우수한 합성 헥토라이트를 제조할 수 있으며, 반응물의 조성비를 제어함으로써, 상기 물성의 제어가 용이한 합성 헥토라이트 제조방법 및 이에 의해 제조된 합성 헥토라이트를 제공한다.
