Description
Technical field
The invention belongs to jewelry production technical fields, are related to a kind of method producing reconstructed amber using amber particle.
Background technology
Amber is a kind of rare organic gemstone, has high ornamental values and the economic values.Amber is used as one kind certainly
Right resource has the characteristics that yield is rare, non-renewable.Natural amber original stone often do not advise by cranny development, irregular colour, size
Then, cleanliness is bad, its practical efficiency is only 65% or so according to statistics, rest part be mostly have it is miscellaneous split, dark-coloured inclusion enclave or size
Too small unserviceable amber waste material, these waste materials are difficult to be machined directly to jewellery or craftwork, usual feelings as natural amber
Direct discard processing under condition.Meanwhile amber jewellery or craftwork are in process, generally also will produce a large amount of leftover pieces and broken
Bits, these leftover pieces and clast generally also can not be recycled directly, and there are the serious wastings of resources.
In the prior art, by the way that resin binder is added in amber waste material, leftover pieces or clast, and amber is pressed
System processing, can produce reconstructed amber.However the technology has the following disadvantages：First, the presence of adhesive, leads to reconstructed amber
Component difference between natural amber is very big, seriously affects product quality and price；Second is that the adhesive being added is easy always
Change, amber particle easily along bonding place fragmentation, influences the beauty and durability of reconstructed amber；Third, the pressing time is long, under room temperature
Need about 15 day time could compression moulding, expend a large amount of manpower and materials；Fourth, the particle contact surface of finished product amber is apparent, particle
Between particle, powder and agitation itself can all form a large amount of intensive bubbles, be distributed in particle junction and near border,
The polishing for influencing amber craft product, makes aesthetics reduce；Fifth, the cleanliness of compacting amber is not improved, wherein impurity or dark
Color inclusion enclave is apparent, seriously affects the quality of amber jewellery or craftwork.
In real work, also have tried to directly press amber using pressure stove in the case where being not added with adhesive
System, but the recrystallization state after clinkering is rendered as outside pressed finished product, but combined not between internal feed particles closely,
There are clear gap or bubbles between naked eyes visible particle, it is difficult to realize higher artistic value and economic value.
Invention content
It is an object of the invention to overcome the deficiencies of existing technologies, provide that a kind of operating procedure is succinct, short time consumption is short, raw
The controllable reconstructed amber production method of at low cost, prosthetic additive, finished product type is produced, the reconstructed amber prepared using this method
Color is good with cleanliness, close structure, and ingredient is completely the same with natural amber.
To achieve the above object, present invention employs following technical solutions：
A kind of production method of reconstructed amber, includes the following steps：（a）Using segmentation pressuring method, heating pressure is carried out to raw material
System；（b）Under protective gas and pressurized environment, pressed amber is made annealing treatment." annealing " described herein is used for reference

As temperature increases the pressure being stepped up to amber, and then realize that amber internal structure is more uniform, fine and close.
Further, the step（b1）The method of middle pressurization is：Protective gas is repeatedly filled with and is discharged into closed environment,
It is finally pressurized to the first air pressure.By multiple inflation/deflation, oxygen, moisture etc. in closed environment can quickly, thoroughly be discharged
Substance avoids the substances such as oxygen in annealing process, moisture and amber from generating chemical reaction.
Further, step（b1）Described in the first air pressure pressure that amber is generated be more than step（a2）In raw material is applied
Add first pressure.In annealing process, the pressure that air pressure generates amber raw material in closed environment is greater than in pressing process
