Problems solved by technology

[0005] The main problems that exist at present are: the pearls grown with lead quality bead cores, the powder produced during drilling is not easy to discharge, which often leads to broken needles; the thermal expansion coefficient of hard paraffin bead cores is quite different from that of nacre. Nacre is prone to blasting; ceramic and glass bead cores are too hard to drill holes; the density of bead cores such as clay, plant seeds, and animal eggs is quite different from that of pearls
Once this resource is destroyed, the loss is immeasurable

Abstract

The invention provides a method for preparing a magnetic and fluorescent bead core from organic glass. In the method, the organic glass monomer material, plasticizer, shell powder and the like serving as ingredients are mixed in a specific ratio; and the mixture is subjected to three process stages consisting of preparation of glue solution, curing and subsequent processing to prepare the magnetic and fluorescent bead core. The prepared bead core has the advantages of safety and innocuity, uniform finesse, high mechanical property, high chemical stability, high acid resistance, high alkali resistance, high solvent resistance, corrosion resistance to substances such as seawater and the like and high biological compatibility; and the high-quality pearl can be cultured by performing insertion after the activation of the bead core.

Description

technical field [0001] The invention belongs to a method for preparing magnetic and night fluorescent bead cores from organic glass. Background technique [0002] So far, saltwater cultured pearls have been nucleated pearls. In addition to having pearl oysters as mother oysters, pearl nuclei are indispensable for cultivating pearls. [0003] The bead nucleus is an important material for producing pearls, and often determines the quality of the pearls produced. The bead core is the material basis for the formation of the nacre, and its composition, structure and properties are closely related to the quality of the pearl. The use of poor-quality bead cores will result in poor-quality pearls. [0004] In the process of pearl cultivation, pearl cores made of lead, silver, clay, pottery, coral, glass, marble and plant seeds have appeared successively, as well as pearl core materials such as mussel shells and clam shells currently used. [0005] The main problems that exist at ...
