Problems solved by technology

For example: use the impurity and decontamination effect of organic solvents such as methanol and acetone to soak pearls to achieve the effect of increasing the pearl's smoothness and gloss, but the disadvantage is that the effect is not very obvious; The decontamination effect is used to soak pearls, especially the complexation and removal of non-ferrous metal ions in pearls, and also achieve the effect of fading and enhancing luster, but the disadvantage is that the effect is not very obvious, the action time is too long, and due to the strong alkali of ammonia water Sex, too long time will cause the luster and permeability of pearls to decrease

Abstract

The invention discloses a nucleated pearl processing technology. The technology comprises steps as follows: a), pearls are soaked in a pretreatment liquid for 25-35 h at the temperature of 10-15 DEG C, the pretreatment liquid is prepared from sodium bicarbonate and distilled water through mixing, 10-15 g of sodium bicarbonate is added to 1000 ml of distilled water, and then washing and natural drying are performed; b), the pearls obtained in the step a) are poured into a brightening device containing a treatment liquid and soaked for 3-5 d at the temperature of 10-20 DEG C, then washing and natural drying are performed, and the treating liquid is prepared from components in parts by mass as follows: 10-20 parts of polyethylene glycol, 10-20 parts of glycerin, 4-6 parts of methylene blue and 900-1000 parts of deionized water; and the like. Compared with the prior art, the technology has the advantages that the brightening effect can be good, transparency of the pearls is not affected, bleaching effect is good, pearl damage is reduced, efficiency is improved, and color and luster is uniform.

Description

【Technical field】 [0001] The invention relates to a nucleated pearl processing technology, which belongs to the technical field of pearl processing. 【Background technique】 [0002] The raw pearls collected from cultured pearl shells, because the outer surface is attached with body fluids and dirt, if left for too long, the colloidal calcium carbonate and organic matter on the pearl surface will condense, the pearl’s color will become dark, and it will be oxidized and deteriorated. Therefore, it should be processed in a timely manner after harvesting. The original beads need to go through a series of fine processing processes such as cleaning→picking→enhancement→punching→color separation→cooking beads→bleaching to become decorative ornaments with technological value. Bleaching is the most critical process in a series of pearl processing procedures, but the existing bleaching process has an unsatisfactory bleaching effect and easily damages the pearls. In recent years, many w...
