Dyeing, it is necessary to control the dye temperature, pH, dye concentration and staining time, these factors affect the staining quality.
Aluminum, stained after washing, drying can be carried out following screen , Swooper Flag Polesdry, closed, dry, protective film, stamping text and graphics, high-light cutting process, Teardrop Flags Wholesale made of high light three-dimensional embossed aluminum signs.
8. Screen plating plaque. The plaque is a product of many signs factory production. Plaque-based metal material, it requires solemnly, obviously, highly decorated. Traditional metal plaque, especially in the brass to corrosion words, note the black lacquer square plaque is the most common. Swooper Flag Poles With the changing of people's aesthetic point of view, the gradual development of commodity economy, the quality of the plaque also has a new and different requirements. Swooper Flag Poles As the sign industry into a screen technology, not only to promote the development of screen technology, but also provide the technical means to develop new products to the sign industry. Advertising Flags For Businesses The new screen legal system plating plaque signage product of the combination of electroplating, screen process. Its basic approach is expressly graphics to screen method, copper, covered with ink to protect non-graphical parts of the trees silver parts of the graphics system electroplating of copper, nickel, chromium, and then mechanical plastic to protect the processing.
The ① process. This process involves the treatment and painting of the electroplating, silk screen, copper plates and metal processing technology, so the more content, the general process is as follows: Teardrop Flags For Sale
Copper materials → prepress processing → → review the production of printed version of the check → → → → dry plating pre-treatment → electroless nickel layer → Cleaning → chrome plating layer → dry cleaning → retreat in addition to printed material → Plastic welding frame → spray varnish check factory
② Main technical rules. Personalized Advertising Flags
a. Screen . Selection of more than 150 mesh nylon or polyester. By direct photographic plate method, the number of coating diazo light-sensitive glue more is better so that when the to get a thick protective ink film. Proofing light engage 1000W metal halide lamps, lamp distance
and b. Pre-plated. Plating pre-treatment fluid formulation and process conditions are as follows
Of H2SO4 160ml / l;
Of H2O2 140ml / l;
CH3CH2OH 120ml / l;
CH3COOH 30ml / l.
, Room temperature;
0.5 to 1 minutes.
Weak corrosion activation solution:
Of H2SO4 10% solution
(c) Electroplated nickel. Electroless nickel formulation and process conditions are as follows
Addition of NiSO4
Saccharin 0.8 ~
BE additives 0.6ml / l;
Dodecyl copper sulfate 0.05 to
of pH 4;
Temperature of 50 to
Mixing the cathode mobile;
Time 30 to 40 minutes.
(d) Chrome plating layer. Chrome plating formulations and process conditions are as follows:
Of CrO3 Additive
Of H2SO4 2.7 to
Cr 2 ~ 5/gl.
Temperature of 50 to
e. Plastic welding frame.
Can be up and down folding, welding block about making the shape as shown in Figure 4-17.
Can hem, upper and lower welding block, as shown in Figure 4-18 shapes.

Surrounded by folding or surrounded by welding block, as shown in Figure 4-19 shapes.
f. Spray varnish to protect the paint. The plaque surface is metal, paint graphics, so, according to supply and capacity, spray cover a variety of clear lacquer can. Transparency, Light, combined with a solid paint better.
9. Imitation metal etching, screen . Imitation of the of metal etching products, visually metal etching effect.
To obtain these results, the substrate surface should have a mirror sheen. With transparent inks printed embossing ink coated on the substrate, the formation of the rough surface of the ground glass, with the combination of a strong contrast between the rough surface to make the appear before the concave-shaped, and its mirror on the of the convex effect. Contrast, the stronger the better imitation of etching. Concave-convex effect is proportional to the thickness of the ink coated. The ink containing the solid ingredients, if you use low-net destination plates, the effect will be even better.
