| titleOfInvention | Method for producing artificial nuclei for cultured pearls |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing an artificial nucleus for cultured pearls, which has no toxicity, is excellent in workability such as perforation processing, and does not cause separation between the nucleus and the nacre. SOLUTION: An organic binder is blended with a mixture of 50 to 70% by weight of calcium carbonate and 50 to 30% by weight of zirconia, and the mixture is subjected to a cold isostatic pressing method to obtain a mixture of 1500 to 150%. A molded body is formed by a method such as pressurizing at a pressure of 2000 kgf / cm 2 . Thereafter, the temperature is equal to or lower than the decomposition temperature of calcium carbonate, particularly 400 to 600 ° C., and further 450 to 5 ° C. Degreasing at a temperature in the range of 50 ° C. Next, the degreased molded body is immersed in an acrylic resin monomer such as triethylene glycol dimethacrylate containing an organic peroxide such as benzoyl peroxide as a polymerization initiator, and the polymerization initiator and the monomer are formed into a molded body. Impregnate. Then 60 The monomer is polymerized by heating at a temperature of ８０80 ° C. for 3 to 8 hours to obtain an artificial nucleus for cultured pearls having a white appearance. |
