Modelling pearl nucleus for pearl culture and preparation method thereof

Abstract

The invention relates to a moulding pearl nuclear used for pearl culture, which comprises a moulding pearl nuclear body. The moulding pearl nuclear used for pearl culture is characterized in that the moulding pearl nuclear body is a composite moulding nuclear body consisting of a soft moulding outer die and a hard moulding inner die which is positioned inside the soft moulding outer die and has the function of supporting. Due to adoption of the structure of the composite nuclear body consisting of the soft moulding outer die and the hard moulding inner die, the advantages of soft materials and hard materials are skillfully combined together, so as to make the moulding pearl nuclear have the advantages during the process of pearl culture: not only the combination tightness of the pearl nuclear and conchs can be effectively improved but also mantles of pearly shellfishs are difficult to frazzle and the bead rate is high; and simultaneously the overall moulding of beads can be guaranteedto be regular and have strong depth perception, and the economic value is high. The invention also relates a method for manufacturing the moulding pearl nuclear. The moulding pearl nuclear and the method can be widely applied to the culture of various pearls.

Description

A kind of shaped pearl core for pearl culture and its production method technical field The invention relates to a pearl core, in particular to a shaped pearl core for pearl cultivation and a manufacturing method thereof. Background technique In the production of known molding pearls at home and abroad, the structure of its molding pearl core is generally a simple molding pearl core body, and the method for making the molding pearl core is roughly two kinds: one is to use impression glue, paraffin wax, PVC It is made of soft materials such as soft plastic and rubber. Due to the poor quality of the material itself, the mold core is often easily deformed due to the certain curvature of the pearl-growing shell during the breeding process, resulting in irregular beads and no three-dimensional effect. Strong, low value, especially when producing larger shaped pearls, the deformation is more obvious; the other is shaped pearl cores carved from hard materials such as shells, brig...

Problems solved by technology

But its fly in the ointment is: because its shaped bead core body is still made of hard plastic, the phenomenon that the mantle of the pearl oyster will be worn out when the pearl is cultivated
