Furthermore, removing organic matter using an alkaline agent requires scrubbing with a brush, which is also expensive.
上記の問題点より、未だ安価なフィラー原料の精製方法
がないのが現状である。Due to the above-mentioned problems, there is currently no inexpensive method for purifying filler raw materials.
（問題点を解決するための手段）
上記の問題点を解決するため鋭意研究した結果、貝殻を
酸化力のある酸に浸すことにより、安価に貝殻に付着し
た有機物を除けることが見出された。(Means for solving the problem) As a result of intensive research to solve the above problem, it was discovered that organic matter attached to the shells could be removed inexpensively by soaking the shells in oxidizing acid. .

’Ｃが望ましい。Shells are made up of nacre, trabecular layer, and outer shell from the inside, and on the surface of this outer shell, various organisms such as algae, barnacles, and other organisms live symbiotically or parasitically. There is. These are organic impurities when used as fillers. The present invention removes these organic impurities,
In order to obtain a filler raw material, shells are immersed in an oxidizing acid and stirred at 20 to 90°C for a required period of time, then taken out of the acid, washed with water, dried, and crushed. An ultrasonic cleaning device may be used when soaking in the acid, and the temperature during stirring is 60 to 90℃ to shorten the treatment time, depending on the concentration of the acid.
'C is preferable.
