Abstract
The invention discloses a precious metal snowflake pattern manufacturing method. The method comprises the following steps of heating precious metal at high temperature for multiple times, and rolling so as to manufacture the precious metal into the required specification, and then carrying out acid pickling and electrolysis on the precious metal, thereby forming the precious metal with snowflake patterns. Crystal lattices of the precious metal can be cracked and recombined for multiple times by the method, and the recombination of the crystal lattices is relatively regular, so that the sizes of the crystal lattices are basically consistent, thereby improving the display effect of the snowflake patterns.
Description
Technical field
The present invention relates to a kind of snowflake line manufacture method, particularly a kind of snowflake line manufacture method of precious metal.
Background technology
The precious metal materials such as gold and silver are usually used in making jewelry, but simple proof gold silver jewellery has aobvious vulgar unavoidably, so usually all can carry out special processing treatment, wherein, manufacturing snowflake line at gold and silver material surface is a kind of comparatively conventional method; And existing snowflake pattern processing method all takes the mode once heated to heat usually, in heat-processed, the lattice of precious metal can carry out restructuring of breaking, but owing to there is various uncontrollability in heat-processed, so the lattice size after restructuring can produce inconsistent, and the inconsistent of lattice size will have a strong impact on the display effect of snowflake line.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of precious metal snowflake line manufacture method, the method can solve the problem that existing technique easily causes lattice fragmentation.
For solving the problem, the technical solution adopted in the present invention is as follows:
A kind of precious metal snowflake line manufacture method, comprises the following steps:
Step 1, carries out melt to precious metal, to make bullion;
Step 2, is baked to 800 DEG C to 850 DEG C, then carries out spreading to bullion by bullion;
Step 3, repeating step 2 pairs of bullions carry out spreading, until bullion is rolled into required specification;
Step 4, carries out impact briquetting to bullion;
Step 5, carries out the baking processing of 800 DEG C to 870 DEG C to the bullion after impact briquetting, baking terminates to carry out cooling process to bullion afterwards;
Step 6, puts into the sulfuric acid water after boiling and carries out pickling by cooled bullion, pickling terminates to clean bullion afterwards;
Step 7, puts into the nitric acid aqueous solution after boiling carry out pickling by the bullion after cleaning, and pickling terminates to clean bullion afterwards;
Step 8, electrolysis treatment is carried out on bullion surface after cleaning;
Step 9, carries out clean to the bullion after electrolysis.
Preferably, in step 2, at every turn must not more than 0.3mm to the spreading thickness of bullion.
Preferably, in step 2, it is 10 to 20 minutes to the baking time of bullion.
Preferably, in steps of 5, it is 10 to 20 minutes to the baking time of bullion.
Preferably, in steps of 5, baking terminates to carry out naturally cooling process to bullion afterwards.
Preferably, in step 6, cooled bullion is put into the sulfuric acid water after boiling and carry out pickling 5 to 15 seconds, and the ratio of sulfuric acid in described sulfuric acid water and water is 1:1.
Preferably, in step 7, the bullion after cleaning is put into the nitric acid aqueous solution after boiling and carried out pickling 5 to 10 seconds, and the ratio of nitric acid in described nitric acid aqueous solution and water is 4:1.
Preferably, in step 8, electrolysis use bath temperature not higher than 25 DEG C, and the time of electrolysis be 5 to 10 minutes, the voltage of electrolysis is 0.5V to 2V.
Preferably, in step 9, the bullion after electrolysis is put into sanitising agent, and adopt ultrasonic wave to clean, the bullion after ultrasonic cleaning cleans with clear water again.
Compared to existing technology, beneficial effect of the present invention is:
1, by repeating implementation step 2 and step 3, the lattice of precious metal can repeatedly be broken restructuring, and lattice is comparatively regular to the restructuring in 850 DEG C at 800 DEG C, makes the size tendency of lattice unanimously, thus improves the display effect of snowflake line; And excessive pressure and too much spreading number of times can make lattice to recombinate, so in a preferred approach, more than 0.3mm, when can ensure that pressure is not excessive, restructuring must not be realized with less spreading number of times to lattice to the spreading thickness of bullion at every turn;
2, in step 6 and 7, carry out pickling, the impurity of precious metal surface can be removed, make the easier electrolysis in the surface of precious metal, improve electrolysis effectiveness with this; Especially, carry out pickling because step 6 and 7 employs two kinds of acid solutions respectively, can avoid single acid solution cannot the situation of wash section impurity, substantially increase the deimpurity ability that disappears;
3, in acid cleaning process, the acidity of acid solution is too low, then cannot dissolved impurity, if acidity is too high, then may corrode precious metal, so the present invention discloses the proportioning of two kinds of acid solutions in a preferred approach, the sulfuric acid namely in sulfuric acid water and the ratio of water are 1:1, nitric acid in nitric acid aqueous solution and the ratio of water are 4:1, use the acid solution of these two kinds of proportionings can removal of contamination to greatest extent;
4, in the process of electrolysis, if temperature, overtension, then electrolysis face of causing is rendered as milky sky crystal face, if voltage is too small, then cannot present crystal plane, so the control of temperature, voltage is particularly important to the formation of snowflake line; Therefore the present invention gives preferred temperature, voltage range values in a preferred approach, i.e. the bath temperature of electrolysis use is not higher than 25 DEG C, and the voltage of electrolysis is 0.5V to 2V, under this electrolytic environments, just can ensure that snowflake line is better formed;
5, the snowflake line manufactured by the present invention is not easy to occur oxidation, even if also without the need to needing strip as existing jewel just like that and again electroplating after oxidation, because the present invention not only forms snowflake line at precious metal surface, precious metal integer in fact after spreading has formed snowflake crystal lattice state all, the snowflake line estimating surface is oxidized or after wearing down, only need suitable process just can reduce, as silver-colored class only need soak wash silver-colored water about one minute just can at its surface renderings snowflake line, and golden class only needs electrolysis again just can.
