Stainless steel wire printing mesh attention points

There are many methods for processing on the surface of stainless steel, which can be roughly divided into two types, one is to treat the stainless steel printing mesh by surface treatment, and the artistic processing of forming the pattern by using the gloss contrast; the other is to impart color in the composition of the pattern. Art processing. Typical examples in which the screen printing method is used are etching processing and ink color processing.

The etching process is to screen the acid-resistant protective film on the surface of the stainless steel, and then etch it with a ferrous chloride solution to form an artistic pattern. The spray color method is to spray the color particles after screen printing to form a pear-like surface to form an artistic pattern.

In recent years, in order to adapt to the diversification of stainless steel use and higher and higher artistic requirements, the development of color-colored "color art" processing method has become the mainstream in this field. Among the methods of imparting color to stainless steel, a method of performing firing using screen printing of a color ink and a chemical coloring method are included.

The chemical coloring art processing method of stainless steel products is: stainless steel products → silk screen → oxidation coloring → alkali treatment → finished product.

The process of etching the art of stainless steel products is: stainless steel products → silk screen → etching → alkali treatment → oxidation coloring → finished product.

The chemical coloring method of stainless steel, instead of using pigments and dyes, is to immerse the stainless steel in a heated concentrated chromium sulfate solution for chemical coloration, which is characterized by good food resistance. The ink used in this processing method requires a very strong acid resistance, and generally uses a UV-curable ink having a special property compatible with the treatment process.

Screen printing of light reflector: A light reflector is a screen printing material that is irradiated with light in the direction of the light source under the illumination of a headlight or other light of a car without being affected by the angle of illumination or the weather. Reflected by the hollow glass particles having a diameter of about 40 μm, the other cores have a reflective layer. Its film-like support has an adhesive layer and a release layer on its surface. Generally, a reflective layer is provided on the acryl resin plate, and the reflective layer is formed by adding a certain amount of hollow glass particles with a resin having high transparency and printing by screen printing. When printing, carefully select the mesh number, the hole width (opening) and the type of hollow glass particles, and the hollow glass particles are regularly arranged. This type of printing is used for various signs and commercials, etc., so that it can be confirmed in darker places. In addition, printing for road signs, airway signs, life-saving appliances, security helmets, etc. can also be considered.

Transfer of anodized aluminum with screen printing: gorgeous and beautiful, brightly colored aluminum is stamped on the stamping machine and displayed on the substrate. Its beautiful color has won wide appreciation. However, sometimes the bronzing machine will encounter products that are not suitable for mechanical bronzing, and the customer stubbornly does not use screen printing gold. In the dilemma, the unique screen printing transfer of aluminum is showing its superiority. The hot stamping machine is mainly based on temperature and pressure, while the screen transfer of electrochemical aluminum relies on the role of adhesive. The reason why the adhesive can transfer the anodized aluminum is because the outermost layer of the electrochemical aluminum is composed of a rubber layer.

In the electro-aluminum transfer operation, the printed image is first made into a screen version, and the graphic on the plate is required to be clear. Then use a screen plate to print a layer of adhesive on the substrate, then attach the anodized aluminum to it, then use cotton or sponge to gently press on the image, dry it, and tear off the anodized aluminum. Dry, tearing is fast), and the parts with adhesives show clear and bright anodized aluminum graphics.

Adhesive formulations are the key to transfer. The formula should be formulated separately according to the nature of the substrate and the nature of the electrochemical aluminum layer and the adaptability of the screen plate. The viscosity and concentration of the formula should be properly formulated.
