Description
Technical field
The present invention relates to noble metal jewelry technology field, specially a kind of process of surface treatment of precious metal.
Background technique
Noble metal generally there are commonly Au Ag Pt Pd and its alloy, manufacture ornaments and industrial components generally use with
Lower process manufacture: it makes by hand, hot investment casting, pressure processing, machining, 3D electroforming, the methods of welding.In noble metal
In pearl class ornament, the pearl class and chain class noble metal jewelry of various styles and moulding, so that the type of precious metal jewelry is complicated, but
Also the technological ability and technical level of manufacturing enterprise are therefore challenged, therefore, noble metal jewelry processing factory is generally provided with stock
Portion, 3D electroforming, with realize noble metal ingot is stretched on various mechanical equipments, punching press, winding, shear, hold mould, press polish,
The operation such as 3D electroforming, reverse mould is that the further processing of other departments prepares preliminary blank, therefore, opens in noble metal processing
The mechanical equipment of hair has pulling plate, drawing machine, tablet press machine, oil pressure die press, punching die press, twisted piece machine, 3D electroforming, reverse mould
Deng.Product class is extensive, can be used for pearl class, falls class, chain class, the classifications such as bracelet class or ring.
In existing noble metal pearl class jewellery, quality, dimensional accuracy and the surface flatness of pearl shape part are all to influence it
The necessary factor of price, during these pearl shape dress ornaments of people's long periods of wear, pearl shape dress ornaments are often by external environment
And be corroded and aoxidize, if people are when wearing gold jewelry, gold can absorb application on human skin toxin or can on skin
Sweat interacts and the jaundice that blacks, meanwhile, gold can also react with the sulphur in the mercury and air in cosmetics and be blacked,
When gold is with platinum phase mutual friction, can also whiten because rubbing upper platinum on the surface of gold, these can all cause gold to lose
Metallic luster and the decorative value for influencing gold；When people wear silver jewellery, desilver can be outer by external environment oxidation, due to silver
Jewellery surface flatness is inadequate, can also accelerate the oxidation of silver surface, and causes silver jewellery to lose metallic luster, and then influence jewellery
Decorative value.In addition, the gold and silver higher due to purity, their pliability is higher, and wearability is lower, works as people
When wearing these jewellery, in long-term scratch, the quality of gold and silver can be reduced slowly, and then cause economic damage to owner
It loses, and the jewellery after scratching cannot keep beautiful persistence, for this purpose, it is proposed that a kind of surface treatment work of precious metal
Skill.
Summary of the invention
The purpose of the present invention is to provide a kind of process of surface treatment of precious metal, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the invention provides the following technical scheme: a kind of process of surface treatment of precious metal, including
Following steps:
S1, grinding and polishing: semi-finished product are carried out to hold mould mill sandpapering, mould finished goods will be held and be polished directly, be polished to
There is the reflective texture of mirror surface on surface, and no sand paper mill beats trace；
S2, paving color sandblasting: paving color sandblasting is carried out to grinding finished goods with sand-blasting machine, pressure control is in 2.0- when sandblasting
Within the scope of 4.0MPa；
S3, it dodges color sandblasting: being laid with after the completion of sandblasting, carry out sudden strain of a muscle color spray using with the paving same abrasive blast equipment of color and tool
Sand, the material of sand are diamond grain or diamond dust, and technical face is patted in atmospheric pressure injection of the allotment sand in 3.0-6.0MPa；
S4, polishing: it is polished with polissoir by sand finished goods is dodged, polishes pearl material selection hard metal, polish pearl
Big ting model is between 2-6mm, and major ting model polishing pearl must be complete, and when polishing, polishing agent was added and alkaline cleaner is thrown together
It washes；
S5, toning: polishing finished goods is mixed colours, and dispels surface impurity spot, and the unified non-uniform face of technical face
Color, steeps sour time control within 2min, and toning finished goods is carried out deacidification cleaning, first with saleratus deacidification to boil water,
Secondly by product spray hot steam cleaning, finished product manufacture immediately is finished.
Preferably, sand paper model, first with the polishing of 60 mesh sand paper, is then beaten with 80 mesh sand paper by thick meticulous in the step S1
Mill is finally polished with 120 mesh sand paper, turns semi-finished product mill to the moist no concave-convex trace in surface.
Preferably, the material of sand uses ball-shaped pearl sand in the step S2, the ball-shaped pearl using sand glass pearl and
White fused alumina pearl, and the thickness model of sand is included between 180-320 mesh.
Preferably, the sand-blasting machine in the step S2 uses ceramics or metal using dry spray or water spraying machine type, nozzle material,
Nozzle inside diameter size is included between 3.0-6.0mm.
Preferably, the sand-blasting machine in the step S4 is selected in cylinder type, submerged type, magnet type and vibration type polishing machine
One kind, the hard metal use one of magnetic bead, wolfram steel pearl and hard ceramic pearl or a variety of.
Preferably, the polishing time of frosted texture product is 30-60min, the throwing of smooth texture product in the step S4
It is 90-120min between light time, the polishing time of mirror surface texture product is 150-180min.
Compared with prior art, the beneficial effects of the present invention are: the present invention utilizes the thin of metal surface multi-layer multi-angle
Micro- plane of refraction texture shows mirror surface and dodges the Visual Interleave sense in sand face, and technical face tactile is smooth, visually has and dodges sand effect,
There is flash-point reflected light under ordinary light irradiation, flash-point reflected light is more strong under strong light, and surface is seemingly covered with hyaline smooth glass
Mirror surface texture, speciality it is wear-resisting it is not easy to scratch, bear dirty it is not easy to change, not only can be to avoid economic loss caused by abrasion, Er Qieke
To keep beautiful persistence, when solving people's wearing jewellery, in long-term scratch, the quality of gold and silver can slowly subtract
It is few, and then economic loss is caused to owner, and the jewellery after scratching cannot keep beautiful persistent problem.
