Problems solved by technology

[0002] The original pearls collected from the 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 color of the pearl 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 → brightening → punching → color separation → boiling beads → bleaching or dyeing to become a decorative ornament with technological value. Bleaching is the most critical process in a series of pearl processing processes, but the existing bleaching solutions are generally solid-phase reagents, the bleaching rate is very unsatisfactory, and the bleaching time is very long

Embodiment Construction

[0007] The present invention is described in detail below: the bleaching solution is used for the pearl bleaching process: first put the screened pearls into a cloth bag, put them into a boiling box, inject clear water into the boiling box and immerse the pearls, heat the boiling box, Place it at a constant temperature of 70-100°C for 3-12 days, take it out, and dry it to form solid bleaching beads; then put the solid bleaching beads into a small bottle for adding light, add bleaching solution to immerse the pearls and exceed 2cm, and the components of the bleaching solution are: Methanol, hydrogen peroxide, methyl ethyl ketone, glycerin and polyoxyethylene sorbitan monooleate, the mass ratio is 100: 4~11: 3~6: 0.2~0.8: 0.4~1; Put it into a large box containing clear water, place it at a constant temperature of 30-40°C for 3-12 days, and then take it out.

[0008] As a preferred manner, the components of the bleaching solution are methanol, hydrogen peroxide, butanone, glycero...

Abstract

The invention discloses a pearl bleach liquor comprising the following components: methyl alcohol, perhydrol, butanone, glycerol and polyoxyethylene sorbitan monooleate at the mass ratio of 100:(4-11):(3-6):(0.2-0.8):(0.4:1). The pearl bleach liquor provided by the invention has boosting effects in bleaching variedness of pearls and promoting the bleaching yield. The yield of the bleached pearls with the assistance of the bleach liquor is above 85%, which is greatly improved, compared with the yield achieved by using the prior art for bleaching.

Description

technical field [0001] The invention relates to a pearl bleaching solution, which belongs to the technical field of pearl processing chemicals. 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. Quality, so it should be processed in time after harvesting. The original beads need to go through a series of fine processing processes such as cleaning → picking beads → brightening → punching → color separation → boiling beads → bleaching or dyeing to become a decoration with technological value. Bleaching is the most critical process in a series of pearl processing procedures, but the existing bleaching solutions are generally solid-phase reagents, the bleaching rate is very unsatisfactory, and the bl...
