Abstract
The invention discloses a formula and a production process method for silver (gold)-filled black copper. The formula and the production process method are characterized by providing a manufacturing method by which artistic effects for better representing metallic coating are achieved and a coating layer cannot fall and fade and even fade at the moment when rubbed off carelessly but can naturally recover primary colors a certain period of time later so as to obtain a satisfactory metal-coated copper works of art. The method consists of a black copper sheet manufacturing process and a silver (gold) filling process. A black copper sheet preferably comprises the following manufacturing materials by weight: 100 grams of red copper, 1.5 grams of gold, 4.5 grams of pure silver, 9 grams of zinc, 2.6 grams of purified earth and 5.2 grams of industrial salt. In the silver (gold) filling process, acidic sweat exerts main effects on a kneading process.
Description
Technical field
The present invention relates to the traditional black copper of China and walk the making of silver process product, specifically is that black copper is walked silver (gold) prescription process for making.
Background technology
Decolouring out of shape and pattern dullness very easily appear in general copper handicraft surface coating layer, lack desirable visual sense, and obscission often occurs according to the conventional method coating material.The invention provides and a kind ofly overcome above-mentioned shortcoming and the artistic effect of exhibit metallic plating and coating layer phenomenon can not occur coming off and fading if careless the wiping falls to fading at that time but can recover the manufacture method of primary colors to obtain the copper art work of gratifying metal deposition by nature after a period of time preferably.
Summary of the invention
The present invention is achieved in that
1, black copper sheet is made:
1.1, adopt smelting furnace (the general smelting used stove) that the red copper of raw material 100 units is heated to fusing point (the red copper fusing point is 1083 ℃) state.
1.2, under the red copper melting state, put into the liquid that can obtain gold (the gold fusing point is 1063.18 ℃) at this moment red copper and gold of 1.5 units.
1.3, remain under the condition of red copper fusing point this state of zinc that red copper and gold liquid are fully merged the fine silver of putting into 4.5 units after 2-3 minute simultaneously and 9 units in temperature and keep after 3-5 minute the purification soil and the 5.2 unit industrial salts (main component natrium nitrosum, chemical formula NaNO2) of 2.6 units are added the purification effect of playing simultaneously.
1.4, continue to keep that all dirt will swim in the alloy liquid surface in 6-10 minute this process of red copper melting temperature, with Impurity removal.
1.5, play pot, pour above-mentioned metallic solution into the strip oil groove, be shaped.
1.7, the alloy material that obtains is naturally cooled to normal temperature (make needed 25 minutes to have difference to 30 minutes according to how many required times of material in 100 gram red copper ratios, reach normal temperature and get final product).
1.8, plate-making, setting-out, blanking, this alloy is forged, rolls the black copper sheet that draw needed shape with (adopting large, medium and small hammer according to size) hammer with pliers (adopting large, medium and small pliers according to size) on hammering block, black copper sheet thickness requirement is 0.5cm.
1.9, the pattern paster, on a paper in the office, described by hand needed pattern line kind or literal lines should be smooth accurately, it is attached on the black copper sheet.
1.10, carve flower, adopt various types of chisels (traditional handicraft chisel such as fried dough twist are carved and comprised various models) press pattern on the paster and carve and carve half following (being below the 0.25cm) of the degree of depth standard crow copper sheet thickness 0.5cm at quarter.
2, walk silver (gold) technology
2.1, fill out silver bits (gold bits), be filled on the black copper sheet engraving tool pattern path with silver bits (gold bits), by heat treatment silver (gold) line and black copper sheet are fused into one with " walking " Man Weidu and are configured as complete pattern.
2.1.1, will walk full silver (gold) powder be heated to fusing point (silver point be 960 ℃, the gold fusing point be 1083 ℃).
2.1.2, reach after the molten state and lower the temperature by water (general domestic water get final product) immediately, cooling rate should be finished in 30 seconds.
2.2, the forming processes of black copper sheet: the black copper sheet welding assembly that will make makes it become complete implements on the copper spare region of interest that has has designed and produced.
2.2, the works of forming are carried out manual grinding, polishing, main is that the silver (gold) that the chief commander crosses shoe polishes with the file, polishing process can adopt manual or mechanical planning machine.
2.4, rub up at last, (it must be acid requiring the palm sweat) with palm sealed while sealing firmly wipe temperature remain on do not stop between 35 ℃ to 45 ℃ to rub up 20-25 minute after in the hand perspiration chemical substance (mainly being acidic materials) produce chemical reaction and reach silver (gold) and the perfect combination of embryo.
2.5, product deposited naturally was advisable in 3-5 days, rubbing up frequency every day is 2-3 time, works are promptly finished.
Points for attention:
1, the black copper sheet fusing point (1083 ℃) of finished product and silver, golden fusing point (silver point be 960 ℃, gold be 1063.18 ℃) close, therefore the requirement for temperature is quite accurate in the process of walking silver (gold).The traditional fabrication method is heated with kerosene lamp and copper blowpipe, and present available blower fan and bellows welding gun are in conjunction with coming temperature is controlled.
2, the production process that rubs up necessarily requires the palm sweat to carry out manual operations for acid people.
Claims (3)
1. black copper is walked silver (gold) prescription process for making, it is characterized in that it is the handicraft of being made by raw material that following ratio is arranged and method:
(1), black copper sheet manufacture craft is formed: make: heat, mix, purify, rise pot, shaping, plate-making, setting-out, blanking, pattern paster, carve and spend.
(2), walk silver (gold) technology: fill out silver and consider forming processes, the polishing of (gold bits), heating, cooling, black copper sheet to be worth doing, polish, rub up.
2. require described black copper sheet preparation method to it is characterized in that the proportioning ratio preferable range of each material according to (1) in the right 1:
The purification soil of the zinc of the fine silver of the gold of the red copper of 100 units, 1.5 units, 4.5 units, 9 units, 2.6 units, 5.2 unit industrial salts.
3. require the described effect that silver (gold) technology is to rub up acidic sweat in the operation of walking according to (2) in the right 1.
