Description
Technical field
The present invention relates to a kind of devices and methods therefor that prevents the oxidation of gold and silver coin, be particularly useful for gold and silver coin collector and use.
Background technology
After the gold coin of a lot of investors and collector's collection, silver coin are placed a period of time, even former factory leak free, owing to preserve improperly, also produced rust staining on the gold and silver coin, article move back level mutually, by the time will be according to article degree of loss grading decline value necessarily mutually when cashing.
The oxidation characteristic of gold coin mainly shows as the rufous rust staining, and big red rust spot diameter has 1～2mm, and is little of fly dung star cloth.Usually the rust staining on the gold coin smooth side is bigger, and the rust staining at concavo-convex positions such as pattern and edge is less, is mostly tiny point-like, have in addition naked eyes be difficult for perceiving.
The oxidation situation of silver coin can be divided three kinds, and a kind of is that the silver coin surface coverage the very thin filbert corrosion layer of one deck, and this corrosion layer does not still destroy the gloss on silver coin surface; Though general casting line time is long or the long period is arranged but preserve environment silver coin preferably, present this state more.A kind of is that electrochemical corrosion has taken place, and colorful, rusty scale is thicker, havoc the gloss and the state on silver coin surface; Usually at the environment that there was dampness in the air, particles in suspension is more, silver coin is easy to generate this type of corrosion.Also having a kind of is the long hickie in silver coin surface, and the red rust spot of situation and above-mentioned gold coin is similar.
Should, the anti-oxidation problem of modern gold and silver coin is present gold and silver coin investor and collector, or even the unit of selling of gold and silver coin, collection unit and coinage industry and coin research institution question of common concern.
To the problem that prevents the oxidation of gold and silver coin, among the people a lot of terms of settlement have been proposed.The lay down location at the gold and silver coin that has is put into natural camphor tablet, perhaps the camphorwood ball; The four jiaos of placement discolour silica gels in gold and silver coin cache that have come the moisture absorption, reach the sludgeproof purpose; What have puts in the best strong box with anticorrosion moisture preventive measure; What have thinks the improvement packing, has corrosive polyvinylchloride with replacements such as not acrid polypropylene, poly-vinyls and packs; Thinking of having touches without hand as far as possible; Have at a kind of invisible protective cover of silver coin surface preparation or the like.Still there are the characteristics that effect is not good enough or technology is too complicated in these methods to a certain extent to the anti-oxidation certain function that played.
Summary of the invention
The technical matters that the present invention will solve is: overcome that existing gold and silver coin oxidation-protective effect is not good enough, the problem of complex process; A kind of anti-oxidation device and method is proposed; This device effect is good, easy, workable, solves the problem of the easy oxidation of gold and silver coin from the source
In order to solve the problems of the technologies described above, the present invention proposes following technical scheme: a kind of device that prevents the oxidation of gold and silver coin, and it comprises a glass ware, plastic casing, active carbon; This glass ware is handled through ground; This plastic casing is placed in this glass ware, and this plastic casing comprises a box body, a lid; The top of this box body offers an opening; This lid covers the top at this box body, and this vent cover is tight; Offer several through holes on this lid; Above-mentioned active carbon is put into this box body from this opening.
The further qualification of technique scheme is that this glass ware is transparent.
The further qualification of technique scheme is that this box body is a cubic shaped, and it is of a size of 5cm * 5cm * 5cm, offers the above-mentioned through hole that 6 diameters are 2mm on this lid, and the weight of above-mentioned active carbon is greater than 2g.
In order to solve the problems of the technologies described above; The present invention proposes following technical scheme: a kind of method of using said apparatus to prevent the oxidation of gold and silver coin; The above-mentioned active carbon that this method comprises the steps: to get constant weight is put into the box body of this plastic casing; Cover this lid, put into this glass ware to this plastic casing and gold and silver coin to be collected then.
In order to solve the problems of the technologies described above, the present invention proposes following technical scheme: a kind of device that prevents the oxidation of gold and silver coin, and it comprises a sealing crisper, plastic casing, active carbon;
This plastic casing is placed in the sealing crisper, and this plastic casing comprises a box body, a lid;
The top of this box body offers an opening;
This lid covers the top at this box body, and this vent cover is tight;
Offer several through holes on this lid;
Above-mentioned active carbon is put into this box body from this opening.
The further qualification of technique scheme is that this box body is a cubic shaped, and it is of a size of 5cm * 5cm * 5cm, offers the above-mentioned through hole that 6 diameters are 2mm on this lid, and the weight of above-mentioned active carbon is greater than 2g.
In order to solve the problems of the technologies described above; The present invention proposes following technical scheme: a kind of method of using said apparatus to prevent the oxidation of gold and silver coin; The above-mentioned active carbon that this method comprises the steps: to get constant weight is put into the box body of this plastic casing; Cover this lid, put into the sealing crisper to this plastic casing and gold and silver coin to be collected then.
Compared with prior art, the present invention has following beneficial effect:
1, thinks why oxidized easily the gold and silver coin is, and reason has a lot, sweat that comprise the decomposed product, water quality, airborne corrosive medium, air humidity of packing, stays after touching with hand or the like.But from the essence of burning, oxidation all is because the oxygen partial pressure of metal environment of living in generates the decomposition pressure of oxide greater than it, so metal can be oxidized.Based on this,, can reach the purpose that suppresses oxidation if can reduce the oxygen partial pressure of gold and silver coin environment.Through a large amount of calculating and experimental verification, obtained the device of above-mentioned anti-gold and silver coin oxidation.
2, the present invention prevents that the device of gold and silver coin oxidation from can effectively prevent the oxidation of gold and silver coin for a long time, and is easy to operate simple, can realize putting things right once and for all.
