How to do brushed imitation red copper process 5

Brushed imitation red copper.

Process] is a kind of coating process on the surface of metal materials, a kind of imitation copper surface copper drawing process with good imitation copper effect, strong copper metal texture, long gloss and color retention time and easy large-scale production.

1. Conventional chemical pretreatment of the surface of the metal material makes the metal surface clean and smooth;

2. Electrostatic spraying.

Transparent red outdoor powder coating with pigments.

or pure transparent outdoor powder coatings;

3. Thermal transfer paper with dark gray and blue straight lines of imitation copper background color is used for thermal transfer printing to obtain the imitation copper drawing effect; Wherein, the thermal transfer paper of dark gray-blue or black straight grain of imitation copper background color, the filamentous straight-grained straight stripe of printing hue dark gray-blue or black on it, and the imitation copper color of its background color is light purple-red, purple-red or light yellow.

Generally, die drawing and electroplating drawing are used, and electroplating drawing is more universal.

Wire drawing process] In the machining surface treatment project, wire drawing is a method that uses the reciprocating motion of the brushed cloth strip and rubs back and forth on the surface of the workpiece to improve the surface finish of the workpiece, and the texture of the surface is linear. It can improve the surface quality and mask minor scratches on the surface.

Drawing imitation red copper process] is a kind of coating process on the surface of metal materials, a kind of imitation copper effect is good, copper metal texture is strong, the gloss and color retention time is long, and the metal surface imitation wire drawing process is easy to produce on a large scale.

1. Conventional chemical pretreatment of the surface of the metal material makes the metal surface clean and smooth;

2. Electrostatic spraying of transparent red outdoor powder coating containing pigment or pure transparent outdoor powder coating;

3. Thermal transfer paper with dark gray and blue straight lines of imitation copper background color is used for thermal transfer printing to obtain the imitation copper drawing effect; Wherein, the thermal transfer paper of dark gray-blue or black straight grain of imitation copper background color, the filamentous straight-grained straight stripe of printing hue dark gray-blue or black on it, and the imitation copper color of its background color is light purple-red, purple-red or light yellow.

What's going on with copper wire drawing? Copper wire drawing is very simple, it refers to the plastic processing method of applying tension to the copper wire to pass through the die hole to obtain the same size and shape as the die hole.

What are the characteristics of copper wire drawing process?

1. Drawing can obtain products with accurate size, smooth surface and complex cross-sectional shape.

2. The production length of the drawn products can be very long, the diameter can be very small, and the section is completely consistent throughout the length.

3. Drawing can improve the mechanical properties of the product.

4. The disadvantages of drawing are: the processing rate of each pass is small, the number of drawing passes is more, and the energy consumption is large.

How to choose copper material before copper wire drawing?

1. The defects of copper rods are often in the continuous casting process and rolling process, which include: residues, copper oxidation inclusions, hot cracking, cracks, and the formation of oxidized particles on the surface of copper rods. Most of the intermetallic inclusions are brittle, which causes cracks to occur during the wire drawing process.

2. The surface defects caused by wire drawing often appear on the surface of bare conductors in the form of drawing die scratches, mechanical damage, arc chisels or splinters. This is usually caused by a misalignment of the moving line in the drawing machine or by the excessive pressing force of the copper refining in the drawing membrane furnace mouth.

3. The elements that can be soluble in the copper matrix mainly include AL, FE, NI, SN, ZN, AG, CD, P and so on. When the content of these elements is very small, it forms a solid solution with copper, which has little effect on the processing properties and plasticity of copper, but reduces the conductivity of copper. It is important to note that these elements form a solid solution with copper, which is relatively hard compared to the copper matrix.

When the casting condition is not good, it is possible to form impurity aggregates, which affects the cold working performance of copper.

4. In this group of elements, P has the most special role and has duality. It is soluble in copper, which significantly reduces the electrical conductivity of copper, but can deoxidize, prevent cold working cracking, and improve the mechanical properties of copper.

5. The impurity elements that are almost insoluble in the copper matrix are mainly O, S, etc., which form compound impurities with copper, which have a great impact on the conductivity of the copper matrix, but the brittle compounds formed will significantly reduce the plasticity of copper. If this compound agglomerate is formed, the effect on the drawing performance of the copper rod cannot be ignored. As a result, copper conductivity and processability can be improved.

However, if the copper matrix is pure, this effect will be smaller. In addition, when the oxygen content is high, if the copper wire anneals in a reducing atmosphere, it will cause "hydrogen embrittlement".

6. The impurity elements that are rarely dissolved in the copper matrix mainly include Bi, Pb, etc. They form soluble eutectic with copper, which will reduce the processing properties of copper. Bi eutectic also exhibits "cold brittleness", which is easy to cause cracking during cold working.

The imitation bronze drawing process adopts the following technical scheme: The imitation copper drawing process, which is characterized by the following steps: 1) conventional chemical pretreatment of the metal surface to make the metal surface clean and smooth;

2. Electrostatic spraying of transparent red outdoor powder coating containing pigment or pure transparent outdoor powder coating;

3) Thermal transfer paper with dark gray-blue or black straight grain imitation copper background color for thermal transfer printing to obtain imitation bronze drawing effect; Wherein, the thermal transfer paper of described imitation copper base color dark gray-blue or black straight grain, the filamentous straight texture straight stripe of printing color dark gray-blue or black on it, and the imitation copper color of its background color is light purple-red, purple-red or light yellow.
