PROCESS FOR MANUFACTURING HIGH-EXPANSION GYPSUM PLASTER COMPOSITION AND HIGH-EXPANSION GYPSUM PLASTER COMPOSITION OBTAINED BY SAID PROCESS
특수한 재료를 이용하는 일 없이 염가의 첨가재로, 게다가, 적은 첨가량으로도, 간편하게, 효과적으로, 범용의 치과용 석고 재료 등의 팽창율을, 종래 기술에서는 달성할 수 없었던 정도까지 향상시킨 고팽창 석고 조성물의 제공, 또한, 예를 들면, 맞물림(적합성)에 문제가 없는 「논클래스프 의치(non-clasp denture)」를 제작하는 경우에 사용되는 복제 모형의 제작에 유용한, 사용하는 수지의 수축에 정밀도 좋게 대응할 수 있도록 경화 팽창율을 적당하게 제어한 고팽창 석고 조성물의 제공을 목적으로 하고, 해당 목적을, 주성분인 소석고에, 2수석고가 함유되어서 이루어지는 분말 상태 석고 조성물 재료를, 건식으로 공분쇄하는 것으로, 경화 팽창율을 높인 석고 조성물을 제조하는 고팽창 석고 조성물의 제조 방법에 의해서 달성한다.
An object of the present invention is to provide a high-expansion gypsum composition in which the expansion coefficient of a general purpose dental gypsum material or the like is simply and effectively improved to such an extent that has never been achieved with conventional technologies without using any special material by adding an inexpensive additive even in a small addition amount, and furthermore another object of the present invention is to provide a high-expansion gypsum composition the setting expansion coefficient of which is appropriately controlled so that the contraction of a resin to be used can be precisely dealt with, the high-expansion gypsum composition being useful for manufacturing a reproduction model to be used in manufacturing a “non-clasp denture” having no problem in, for example, occlusion (adaptability). The objects of the present invention are achieved by means of a method for producing a high-expansion gypsum composition, the method producing a gypsum composition having an enhanced setting expansion coefficient by copulverizing in a dry system a powdered gypsum composition containing calcined gypsum as a main component and dihydrate gypsum.
