Abstract

PROBLEM TO BE SOLVED: To easily reforme when needed by firing porcelain and stains at high temperatures at each of respective stages, thereby obtaining gloss and tints having depth and attaining physical and chemical stability. SOLUTION: A plaster model of the fingertip part of a wearing person is formed from an impression taking of this fingertip part and the impression of the main model is taken. A refractory model of the impression picture is formed as a duplicate model. Oxide ceramic mud of particulates is applied to the nail part of this duplicate model and the layer of the solidified particles is formed on the model and is trimmed to the form of an artificial nail reserve base plate of about 0.4 mm in thickness by means of a knife. The model is then fired at about 1,120 deg.C in a furnace. Mixed mud of glass powder is applied to its surface and is subjected again to osmotic firing at about 1,100 deg.C. A porous reserve base plate is penetrated with the glass, by which a high degree of the deflection strength is obtained. A base plate 2 is thereafter obtained by subjecting the base plate to form correction. This base plate is so polished as to comply with a nail of the main pattern and is finished as an artificial nail 1.

The refractory model immediately absorbs the liquid component of the ceramic mud, leaving a layer of condensed particles on the model. This condensed layer is scraped to make a spare base for the nail. The mixed mud of glass powder is applied to the surface of the sintering and sintering base, and the base (2) is finished by sintering and firing at about 1100 ° C. This non-porous and homogeneous structure provides a stable artificial nail. A desired color design is drawn with a stain on the surface of the base (2), and the artificial nail (6) finished by glazing is adhered to the raw nail with an adhesive, so that it is gentle on the body without discoloration or deterioration. It is well suited and can be used as an artificial nail that is as thin as 0.4 to 1.2 mm and hard to break.

義爪として利用できる。Example 1 A gypsum model was prepared from an impression of a fingertip including a nail of a wearer based on a method described in the specification of EP86440081, and a tip of the plaster model was formed with wax as required. The length, shape, and curve are added to make a main model, an impression of the main model is taken, and a refractory model of the impression surface is created to make a double model. On the claws of the compound model,
Apply fine particles of oxide ceramic mud, make a layer of condensed particles on the model, prepare a 0.4 mm thick artificial nail preliminary base with a knife, and bake at 1120 ° C with a furnace. Then, a mixed mud of glass powder is further applied to the surface of the sintered preliminary base, and sintering is performed at about 1100 ° C.
By performing this infiltration firing, a high degree of flexural strength can be achieved by infiltrating the porous preliminary base with glass.
Thereafter, the form is corrected to obtain the base (2). Polish to match the nail of the main model and finish as artificial nail (1). Further, when the mixed oxide is present as spinel in the structure, an artificial nail can be formed in the same process. It can be used as artificial nails with natural color and transparency for those who have no nails (including animals) and those who have malformed nails due to congenital or accident.

There is a way to do it. As an adhesion method, there is a use of an α-cyanoacrylate adhesive having a strong adhesive force, but since the artificial nail of the present invention is excellent in conformity, it is easier and more convenient to use a double-sided tape for adhesion with a raw nail. . The adhesive strength is adjusted by the size of the contact area between the double-sided tape and the artificial nail. As another application, the present invention can be used for accessories such as piercings, earrings, and pendants, in which a part of an artificial nail is provided with a holding hole.
