Description
Technical field
The invention belongs to a kind of method that improves sea water pearls gloss.
Background technology
Sea water pearls is by CaCO
3Aragonite or calcite crystalline solid form with organic (mainly being the shell keratin) mutual accumulation.Organic matter mainly is between pearl nuclear and the nacre and in the nacre crystalline solid layer.Carry out alkali treatment and organic solvent and handle, some organic matters in the leachable pearl are absorbed minimizing when making light see through nacre, and reflection, the amount of refraction of light in nacre increases, and pearly luster is improved.
The shell keratin has certain stretching, extension, folding property.Pearl is carried out appropriate alkali treatment; Make the shell keratin change the anion attitude into by electroneutral; Keep the key that the electrostatic interaction between necessary some the oppositely charged group of shell keratin molecule space conformation forms with temporary transient destruction; Can make the shell keratin be in the state of " loose ", make the part substance dissolves to alkali lye.Handle with organic solvent again, can play the space structure picture of some hydrophobicity macromolecular substances of abundant adjustment, help the effect of water-soluble bleaching agent in the following bleaching process, and can also dissolve some fluorescent materials, long carbochain saturated fatty acid (or fat) etc.
China's pearl process technology all comes from Japan at present, and Japan strictly maintains secrecy to its technology.At present, for improving the backward in technique of sea water pearls gloss, treatment process is unreasonable, and the processing time is oversize, DeGrain.
Summary of the invention
The purpose of this invention is to provide a kind of method that improves sea water pearls gloss; Sea water pearls is carried out alkali treatment (magnesium hydroxide and ammoniacal liquor) and organic solvent (methyl alcohol) processing, and some organic matters in the leachable pearl are absorbed minimizing when making light see through nacre; Reflection, the amount of refraction of light in nacre increases; Pearly luster is improved, and helps the effect of water-soluble bleaching agent in the following bleaching process, shorten the sea water pearls bleaching time.
The present invention includes following steps:
(1) prepare following solution, used chemical reagent is pure for analyzing:
A1 liquid: 8g～10g magnesium hydroxide and 20mL～25mL ammoniacal liquor are added in the 500ml distilled water, stir, filter insoluble matter,, subsequent use with distilled water diluting to 1000mL;

A3 liquid: 8g～10g magnesium hydroxide and 3mL ammoniacal liquor are added in the 500ml distilled water, stir, filter insoluble matter,, subsequent use with distilled water diluting to 1000mL;
B liquid: the Macrogol 2000 of 10g～15g is joined in the 1000mL methyl alcohol, shake up, subsequent use;
C liquid: with 5mL～10mL ammoniacal liquor join in 990mL～995mL distilled water, shake up, subsequent use.
(2) technical process
1) pearl is immersed in the flask under 18 ℃～20 ℃ water bath condition with A1 liquid, liquid level exceeds pearl 1cm～2cm, 2 days afterwash, oven dry;
2) pearl is immersed in the flask under 40 ℃～45 ℃ water bath condition with B liquid, liquid level exceeds pearl 1cm～2cm, 3 days afterwash, oven dry;
3) pearl is immersed in the flask under 40 ℃～45 ℃ water bath condition with C liquid, liquid level exceeds pearl 1cm～2cm, 2 days afterwash, oven dry;
4) pearl is immersed in the flask under 40 ℃～45 ℃ water bath condition with A2 liquid, liquid level exceeds pearl 1cm～2cm, 3 days afterwash, oven dry;
5) pearl is immersed in the flask under 40 ℃～45 ℃ water bath condition with C liquid, liquid level exceeds pearl 1cm～2cm, 2 days afterwash, oven dry;
6) pearl is immersed in the flask under 40 ℃～45 ℃ water bath condition with A3 liquid, liquid level exceeds pearl 1cm～2cm, 3 days afterwash, oven dry.
Clean, drying requirement in the above-mentioned technical process are:
Clean: adopt plastics or the wooden pearl bucket of washing, clean with clear water earlier, embathe with Gao Fuli board liquid detergent then, the no mucus to the pearl surface is used till clear water rinsing to the non-foam again;
Oven dry: in 45 ± 2 ℃ of left and right sides convection oven, dry.
The method of the invention can obviously improve the gloss of sea water pearls, and the chemical reagent of being selected for use can be bought in general chemical industry shop and obtain, and technology and flow process are simple, easy master, and with low cost, has favorable actual application and is worth.
The specific embodiment
After sea water pearls handled with A liquid, sea water pearls faded obviously, and this molecular structure change with coloring matter is relevant; Handle back pearly luster with B liquid and obviously strengthen, this is that light reflection, refraction increase because the separating out of the coloring matter that is dissolved in organic solvent between aragonite interlayer or pearl nuclear and nacre in the nacre is absorbed minimizing when making light see through nacre; After handling with C liquid, it is transparent that pearl obviously becomes, this with nacre between the water colo(u)r material separate out relevant.
