Description
Technical field
The utility model relates to pearl identification technology field, the non-damage drive of specially a kind of pearl type and pearl thickness degree
Device.
Background technique
Biogenic pearl is described as " jewel queen " by common people.South China pearl is even more that jewelry circle personage and consumer are preferred
World-famous rare product.Nowadays pearl culture has spread Asia America and Europe.Produce the main Asian countries of natural seawater pearl
There are China, Iran, Saudi Arabia, Sri Lanka, Burma, Fiji and Philippine, mainly there are Venezuela, Mexico, Panama in America
Deng also Australian.Produce natural fresh water pearl country have Europe Scotland, Venice, Ireland, France, Germany,
Russia etc..The Mississippi Valley in the U.S., Iran northern river region, the Heilungkiang of China, Huaihe River, the middle and lower reach of Yangtze River
The Qingjian River, river Han one with and TAI HU AREA, also all produce natural fresh water pearl.
For a long time, consumer is beyond recognition sea water pearls and fresh water pearl, often has some bad businessmans inexpensive
Fresh water pearl serve as valence it is high sea water pearls sale make profit.Occurs the seawater largely through dyeing processing again in the market in recent years
Pearl and fresh water pearl product are difficult to distinguish natural colourful pearl and artificially colored pearl from external appearance characteristic.
But then can clearly it distinguish from the section of pearl.The pearl layer color of natural colored sea water pearls section can be divided into
Two types, one kind are that pearl layer color is uniformly distributed, and another pearl layer color has concentric annular structure, and every layer of shade is not
One.And artificially colored sea water pearls, in outer layer from its visible color set of section, ecto-entad is gradually become shallower as, with natural colour
The Color Distribution Features of sea water pearls have significant difference.These features of pearl section can be used as identification foundation, but such
Identification needs to destroy sample.In addition to dyeing pearl technology height confidentiality, dye type used is difficult to define for each producer at present,
Also identify artificially colored sea water pearls and there is uncertainty.
When there is foreign matter to enter in pearl oyster mantle, secretion coats foreign matter layer by layer, forms pearl by long time.
It is rare and rare due to pearl, occur the emulation pearl of plastics in the market.And emulation technology is continuously improved, very
It is difficult to be distinguished with genuine pearl.
Manually slotting core is carried out when cultured pearl, i.e., foreign matter is manually inserted into pearl oyster and is cultivated, cutd open freshwater mussel later and take
Pearl.In order to obtain big pearl as early as possible, some are manually inserted, and core is larger, and big pearl can be obtained as long as the relatively thin pearl layer of core outer cladding.It is such
Pearl surface is really nacre, does not split and is difficult to measure its pearl thickness degree.
Existing X-ray and near-infrared pearl pearl layer thickness gauge can only detect pearl layer and pearl core combination defective tightness
Pearl pearl thickness degree.But for the pearl thickness degree and other physical features of those pearls layer and the compact pearl of pearl core
Identification, X-ray and near infrared technology are helpless.And for excessive (diameter be greater than 11.5mm) or excessive (diameter is less than
Pearl 5.5mm) can not also detect.
Insider is dedicated to studying the feature of the electromagnetic spectrum of different type pearl, it is desirable to thus find pearl Undamaged determination
More preferable method.
Research finds that pearl has its own unique institutional framework as the eyes of our people.The lines pair of human eye iris
Everyone be it is unique, do not repeat.Similarly, the organization construction of different pearls also has uniqueness, non-imitability
And the features such as identification convenience.Nacre is mainly formed by carbonic acid calcium analysis minor metallic element and organic matter organized polymerization, this
The elementary particle of substance is quark and electronic configuration into regular array, and different pearl layers has different histoarrays.Column
Each electronics or each quark in battle array have oneself independent string, under the effect of external force the quark and electronics of different arrays
String can deform.When external force is fluctuation, quark and electronics string can be shaken therewith, and energy needed for string shake is each
It is different.If the size of the quark of the inside of different type pearl and the shake rule of electronics string and required energy can be detected,
Different types of pearl can be differentiated accordingly and knows the characteristic informations such as pearl thickness degree.But have not yet to see related such pearl
The report of the method or apparatus of detection.
