| titleOfInvention | How to get pearl oyster nacre powder |
| abstract | (57) [Summary] [Problem] The use of pearl oyster shells has progressed, but there are some problems, and it is necessary to find more utility value and to increase the use of shells that are discarded even at present. A pearl oyster shell is placed in a rotary tiltable barrel polishing machine and treated with a polishing liquid and a polishing stone. The polishing liquid used is 0.5 of the amount required to convert calcium carbonate in the portion excluding the nacre of the pearl oyster shell to calcium chloride. Use an aqueous solution of hydrochloric acid in an amount of 1 to 1.5 times. By this treatment, the pearl layer of the pearl oyster shell is preferentially obtained, crushed, immersed in ethanol, and then dried to obtain the pearl pearl layer powder. In addition, in addition to the above method, when treating with hydrochloric acid in a rotary tiltable barrel polishing machine, Process in a sealed state. The pearl oyster pearl powder according to claim 1, wherein the pressure is reduced by one or more valves provided in the rotary tiltable barrel polishing machine after the treatment. |
