Problems solved by technology

Although the adhesive bonding method is an effective method for fixing the bead core, it has many disadvantages: (1) because the shell has a certain degree of concavity, the inserted bead core is particularly pasted like a shaped bead core. There is a large gap between the surface and the shell, and the amount of adhesive used is not easy to control: if the amount is small, the adhesion will not be strong, resulting in denuclearization; if the amount is too large, the adhesive will overflow the edge of the bead core, thereby affecting the shape of the pearl.
(2) The adhesive will be toxic to the epithelial cells that secrete the nacre on the mantle, and will also affect the growth of the nacre and the quality of the pearl
Although good results were achieved without the use of adhesives in the paper "Research on the Cultivation Technology of Mazu Figure-shaped Pearls", each shell can only insert one figure-shaped pearl core, and the pearl oysters used are freshwater pearl mussels, and It is not suitable for seawater pearl oysters, because the mantle of freshwater pearl oysters has the physiological characteristics of attaching along the edge of the shell, and the mantle of seawater pearl oysters shrinks severely after peeling off. of

Embodiment 1

[0017] The making of magnetic bead core: drill a hole in the center of the bottom surface of hemispherical or large hemispherical bead core body 1, and the depth is the height of flat cylindrical NdFeB fixed magnet 2 or slightly shallower; embed fixed magnet 2 in the hole, so that The bottom surface of the fixed magnet 2 is flat or slightly protruding with the bottom surface of the bead core body 1, and is bonded with an adhesive; the soft glue film 3 is installed on the fixed magnet 2 and the bead core body 1 bottom surface to make a magnetic bead core.

[0018] Implant and fix the bead nucleus: open the seawater pearl oyster or freshwater pearl oyster with an opener, and tie the mouth with a wedge; use a flat and smooth head to separate the mantle of the predetermined nucleus of the above-mentioned pearl oyster from the inside of the shell 5, and place the magnetic The bead core is placed on the predetermined core position; dry the seawater outside the shell 5 of the predeter...

Abstract

The invention provides a method for breeding blister pearls by using magnetic attraction to fix pearl nuclei. The method includes the steps of connecting a strong magnetic material to one side of the bottom surface of a traditional blister pearl nucleus; wrapping the pearl nucleus with an anti-corrosive and skid-proof soft glue film on the outer side to form a magnetic pearl nucleus; disposing the magnetic pearl nucleus in a preset nucleus position on the inner side of a shell; fixing another strong magnetic material in the same position on the inner side of the shell so as to fix the magnetic pearl nucleus in the preset nucleus position under the attraction between the two magnetic materials; and breeding the nucleus-transplanted shell in the sea area for a certain period of time to generate a magnetic blister pearl. The method has the advantages of convenient use, good effect of pearl-nucleus fixation, reduced time for nucleus-transplanting operation, reduced nucleus-transplanting efficiency, and lowered mortality rate for shells after operation, thus overcoming the deficiency in prior method of breeding blister pearls that uses cementing compound to fix pearl nuclei.

Description

technical field [0001] The invention relates to a method for cultivating pearls, in particular to a method for cultivating pearls with shells by using magnetic attraction to fix pearl nuclei. Background technique [0002] Shelled pearls are an important part of cultured pearls, and are widely used in pearl pendants, pearl rings or other inlaid pearl ornaments. Compared with free pearls, they have the advantages of larger particles and cheaper prices. The types of pearl oysters that cultivate shelled pearls include penguin pearl oysters, large pearl oysters (white butterfly oysters), pearl oysters (black butterfly oysters) and river mussels. Among them, river mussels are freshwater pearl oysters, and the others are seawater pearl oysters. The shellfish that shell pearls are mainly river mussels and penguin pearl oysters. The cultivation technology of shelled pearls is fundamentally the fixing technology of pearl cores. At present, most of the pearl core fixing methods used i...
