Abstract
The invention relates to a surface treatment method for enabling black copper works to have ugyen effect. The technical aim to be realized by the method is that the black copper works have more realistic ugyen luster and stronger wrapped slurry. The method comprises the following steps of: putting the black copper work on a turntable, uniformly heating the surface by a manner of flaming, and when the temperature of the surface achieves 300-280 DEG C, brushing K2S liquor according to the use quantity of 0.3-0.5 ml/cm<2>; secondarily heating by the manner of flaming after waiting for at least 8 hours, and when the temperature of the surface achieves 150-140 DEG C, brushing Fe(NO3)2 liquor according to the use quantity of 0.3-0.5 ml/cm<2>; heating by the manner of flaming for at least six times, and when the temperature of the surface achieves 150-140 DEG C, alternately brushing K2S liquor and Fe(NO3)2 liquor; and wiping the work with a piece of flannelette until the surface is in glossy black.
Description
Technical field
The present invention relates to metal finishing, specifically a kind ofly make black copper works there is the surface treatment method of coal effect.
Background technology
Coal surface is pitch-black shinny, and bag slurry moistens, and shows fully luxurious steadyly, can be rated as the king of precious metal.In order to make black copper there is the metal brilliance of coal, in prior art, also there is some trial.As Chinese patent literature CN102233778A discloses a kind of " black copper is walked silver (gold) formula process for making ".It is made and walks silver (gold) technique twice program by black copper sheet and forms.The material mixture ratio preferable range that crow copper sheet is made is: the fine silver of the red copper of 100 units, the gold of 1.5 units, 4.5 units, the zinc of 9 units, the purification soil of 2.6 units, 5.2 unit industrial salts.Walking and integrating operation in silver (gold) operation is mainly to be worked by acidic sweat.But it is reported the product that the method obtains, coal brilliance is untrue, bag slurry easily peels off, and wear resistance erosion resistance is also not high.
Summary of the invention
The technical issues that need to address of the present invention are, make black copper works have coal brilliance more true to nature, and bag slurry is more firm.
Of the present inventionly make black copper works there is the surface treatment method of coal effect, as follows:
1) smelt black copper: be weight %, phosphorus 0.0006～0.0008, nickel 0.00015～0.00025, iron 0.0007～0.0009, lead 0.0007～0.0009, tin 0.0008～0.0010, silicon 0.00035～0.00045, zinc 0.0005～0.0015, all the other are copper;
2) by design requirements casting works;
3) work surface processing: sandblast, polishing, is polished to roughness not higher than Ra0.1;
4) coal processing:
The K that a, preparation concentration are 5%
2s solution, the Fe (NO that concentration is 1%
3)
2solution, coal gas and flame gun;
B, works are placed on rotating disk, and the heating of surface uniform flame, reaches 300～280 DEG C, by 0.3～0.5ml/cm to surface
2consumption is brushed K
2s solution; After at least waiting for 8 hours, the 2nd flame heating again, reaches 150～140 DEG C, by 0.3～0.5ml/cm to surface
2consumption is brushed Fe (NO
3)
2solution; 6 flame heating at least again, all cause surface and reach 150～140 DEG C, and alternately brush K later
2s solution and Fe (NO
3)
2solution;
C, flannelette wiping work surface are to glossy black.
Preferred flame heating total degree is 8～10 times.
Compared with prior art, simply effective by the inventive method, handled product, its surperficial coal brilliance is more true to nature, and bag slurry is more firm.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1.According to the following steps:
1) smelt black copper: make in % by weight, phosphorus 0.0007, nickel 0.0002, iron 0.0008, lead 0.0009, tin 0.0009, silicon 0.0004, zinc 0.001, all the other are copper.
2) by one, the design requirements side of casting inkstone.
3) sandblast is carried out in inkstone surface, grinding process, being finally polished to roughness is Ra0.08.
4) coal processing
The K that a, preparation concentration are 5%
2s solution, the Fe (NO that concentration is 1%
3)
2solution, coal gas and flame gun (Shanghai Spraying Machinery Plant's production).
B, inkstone are placed on rotating disk, and the heating of surface uniform flame, reaches 300～280 DEG C, by 0.33ml/cm to surface
2consumption is brushed K
2s solution; The now very fast blackening in copper inkstone surface.Then wait for 8 hours to promote coating in conjunction with stable.The 2nd flame is heated to surface and reaches 150～140 DEG C again, by 0.33ml/cm
2consumption is brushed Fe (NO
3)
2solution, makes pitch-black intensification.The 3rd flame heating, reaches 150～140 DEG C, then presses 0.33ml/cm to surface
2consumption is brushed K
2s solution makes pitch black layer form bag slurry.The heating of the 4th flame, reaches 150～140 DEG C, then presses 0.33ml/cm to surface
2consumption is brushed K
2s solution is brushed Fe (NO
3)
2solution, makes pitch black bag slurry shinny by gesture.Repeatedly 6 times so again, inkstone table twister feels more perfect.
C, flannelette wiping inkstone surface.Work surface is pitch-black shinny, and bag slurry moistens, and equals to coal, several looking genuine.
Wearability test: 200 order silicon carbide, 9 kilograms of pressure/cm
2air pump, 1 meter of distance is far away, sprays that not reveal copper true qualities 10 seconds be qualified.Product of the present invention sprayed for 15 seconds and does not reveal copper true qualities, and wear resistance is relatively good.
