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 pearl brightening technology. The pearl brightening technology comprises the following steps: a) pouring polyethylene glycol, glycerol, methylene blue and de-ionized water into a container and uniformly mixing to prepare brightening liquid for later use, wherein the mass ratio of each component is as follows: 10 to 20 parts of the polyethylene glycol, 10 to 20 parts of the glycerol, 4 to 6 parts of the methylene blue and 900 to 1,000 parts of the de-ionized water; b) pouring the brightening liquid and pearls to be treated into a brightening device and immersing for 3to 5 days at the immersing temperature of 10 to 20 DEG C; then washing with water, naturally drying and the like. Compared with the prior art, the brightening effect can be good and the permeability of the pearls is not influenced.

Description

【Technical field】 [0001] The invention relates to a pearl lightening process, which belongs to the technical field of pearl processing. 【Background technique】 [0002] In recent years, many workers have carried out research on pearl enhancement treatment 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 If the time is too long, the luster and permeability of pearls will be reduced. 【Content of invention】 [0003] The object of the present inve...
