Method for coloration and pigmentation of black pearl

Abstract

The invention relates to a technology for processing black pearl, in particular to a method for the coloration and the pigmentation of the black pearl. The method for the coloration and the pigmentation of the black pearl includes: raw materials of water, ethanol, methanol and black dye are prepared; pearl is sequentially perforated, soaked and dehydrated, and temperature in a thermal cultivation box is regulated from low to high values; and the atomized water, ethanol, methanol and the black dye raw material are utilized for the circular treatment of coloration and temperature control on the pearl, the time of each circular treatment ranges from 36 to 180 hours, and the finished product is obtained after the steps of generation, elution, drying, and the like are carried out. The method has the advantages of favorable effect of coloration and pigmentation, effective improvement of shining bright color of the natural pearl and hard discolouration, and maintains the original quality of the pearl, thereby increasing the commodity value of the pearl.

Description

technical field [0001] The invention relates to a pearl processing technology, in particular to a black pearl color dyeing method. Background technique [0002] In order to improve the appearance quality of pearls, pearls are often processed by dyeing methods to achieve the color and luster that meets people's needs. The current dyeing method is generally achieved by soaking pearls in dyes and surfactants for a long time, such as Chinese patents "a kind of seawater cultured pearl dyeing solution and its preparation method" (application number 200510042164.1), "a kind of pearl "Dyeing method" (application number 200510049714.2), "a pearl dyeing method combining nano-carbon and reactive dyes" (application number 200810219390.6), etc., these methods all have different procedures to produce chemical reactions on the pearl surface, and their shortcomings are The coloring effect is poor, and the bright color of natural pearls cannot be effectively maintained, which destroys the i...
