Problems solved by technology

Institute of Technology, Guangdong Academy of Agricultural Sciences 60 Co irradiated color change has achieved preliminary results, but it has not been applied to production because the treatment conditions are not easy to control and the cost is high.
At present, my country's pearl dyeing technology is still based on dye dyeing, but the color of the dyed pearls is not bright enough, and it is easy to fade and has poor stability.

Embodiment Construction

[0007] Weigh 0.120g of neutral brilliant red S-BRL dye with an electronic balance, put it into a small beaker, dissolve it with deionized water, then add surfactant Tween-80 (Tween-80), stir, and wait until the dye and surface activity After the solvent is completely dissolved, use a 250mL volumetric flask to make up to volume. Finally, adjust the pH value to 8.20 with dilute ammonia water, and reserve it for pearl dyeing.

[0008] The dyestuff in the present embodiment can be used instead neutral brilliant yellow S-5GL, neutral bordeaux GRL, neutral black S-2R, reactive red ST-3BF, reactive black ST-ED and reactive yellow ST-4RFN, used at this moment The solvent and surfactant were replaced by seawater and sodium lauryl sulfate, ethanol and Tween-80, deionized water and Tween-80, deionized water and polyethylene glycol dimethyl ether, seawater and Tween-80, Sea water and polyethylene glycol dimethyl ether. After screening, it is known that the corresponding coordination amo...

Abstract

The invention discloses a pearl coloration liquid for mariculture comprising colorant, surface active agent and dissolvent, wherein the concentration of the colorant and the surface active agent is 0.4-0.6g / L. Its preparation comprises weighing the colorant, choosing the corresponding dissolvent for dissolving, charging corresponding surface active agent, stirring to dissolve the latter, keeping constant volume with the corresponding dissolvent, and adjusting the pH to 8.00-8.60 with alkali.

Description

technical field [0001] The invention relates to a seawater cultured pearl dyeing solution and a preparation method thereof. Background technique [0002] The dyeing of marine cultured pearls plays an important role in its optimal treatment. On the one hand, the color of pearls can be diversified through dyeing to meet different needs; on the other hand, pearls with poor bleaching effects can also be dyed to improve their appearance. Properly dyed pearls have significantly improved iridescence, brightness, fullness, etc., giving people a sense of sparkling pearls and crystals. The research on pearl dyeing technology started relatively late, and Japan's dyeing technology is the most advanced, while domestic pearl dyeing technology is relatively backward. Institute of Technology, Guangdong Academy of Agricultural Sciences 60 Co irradiated color change has achieved preliminary results, but it has not been applied to production because the treatment conditions are not easy to ...
