New metal screen printing widely used printing technology with good effect

Date:2013/9/2 20:28:16 Hits:5424

       Metal screen printing range is very wide, can print all kinds of signs, panels, signs and metal forming products, etc.They mostly decorated with direct printing, no much difference in screen printing techniques, just metal products are durable, surface decorative requirements higher, more durable, so before printing surface processing, such as surface coating, electroplating, anode oxidation and mechanical play MAO (brigade grain, drawing), etc.Printing, to ensure that the surface is clean, so be sure to wear gloves when working.If treated on the surface of product such as grease, fingerprints and dust stains, must use solvents such as trichloroethylene, diluents and petrol for.In addition, according to the surface of the metal to choose the appropriate printing ink performance, such as amino paint and epoxy coating on the surface of the lacquer that bake, amino and epoxy resin with thermosetting ink;Nitrocellulose lacquer and other natural drying coating, can use type solvent evaporation or oxidation drying inks, but must be careful with solvent or diluent, in order to prevent the destruction of paint, and after printing cover coating a layer of light oil, in order to improve the luster and protection of the surface;Metal plating surface can also be used thermosetting ink printing, but must pay attention to the electric plating and the difference in thermal expansion coefficient of metal, to control the heating temperature, avoid coating cracking resulted from the difference expansion coefficient;The anodic oxidation of aluminum plate can form a space uniform layer of oxide layer (about 2 ~ 10 microns thick), has a larger surface area, can improve the adhesion of the coating (ink), in addition, there is the performance of the adsorption of dye diffusion type ink or disseminated legal system for dyeing.
      1.Screen printing corrosion plates corrosion plates is a traditional sign, species are used as the instrument panel fill paint panels, sandblasting oxidation number used for vehicle license plate, equipments and various machine tool electrical corrosion baking enamel signs nameplate, of mechanical and electronic products used in industrial environment is poor, copper plating front panels, as instruments, electronic instrument surface decorative porcelain paint signs, oxide and glossy plates, etc.These signs on the graphic in the past are all from liquid photosensitive glue (fibrin glue, bone glue, gelatin, pva glue, etc.) by photochemical method now.The advantages of this method by deformation of the small, but the existing production process more production efficiency is low, many defects such as the intensity of labor and energy consumption.By adopting the method of silk screen printing graphic, several times can improve the production efficiency, save a large amount of auxiliary materials and energy.For readers under the concrete corrosion sign by screen printing technology.

     2.Screen printing aluminum oxidation dyeing brands aluminum oxide plate, the surface smooth, hard wear-resisting durable.

     Aluminum oxide signs, panels after oxidation closed surface has a layer of oxide film, the surface is hard and smooth.With general screen printing ink adhesion is poor, often should pay special attention on this point.To solve this problem, must first solution loss of screen printing ink and operational problems.Using alumina screen printing ink, is the solution of alumina in the printing ink film adhesion, strong degree such as the key to the problem.The ink is different from general ink, it will firmly adhere to the aluminum plate, and also has good light fastness, is an ideal printing ink to printing aluminum anodic oxidation plates.

       3.The characteristics of the printing and color aluminum plates convex concave plates is painted in sunken place, good abrasion resistance, it also has the stereoscopic effect, more used by mechanical plaque and plaque, etc.Traditional method is to use artificial in corrosion of the sunken place painted (or with needles note paint), next reoccupy hand finish, remove residual paint edges.This method not only time-consuming, low efficiency, require the operator to have skilled techniques, and make signs often faces words is not clear, the handwriting deformation, the quality is not stable.Therefore, only to make some small batch, less chromatic number, quality is not high, the design is very simple.

      4.Silk screen embedded sandblasting oxidation coating aluminum label printing embedded sandblasting oxidation paint label process, is a traditional sign making craft.This kind of product appearance is silvery white, high surface hardness, good wear resistance.

       5.Screen printing wood from alumina plates water white alumina plates is recently in our country in a new type of the photon surface sign.This sign a milky appearance, smooth surface smooth, no AoTuGan, wet and heat resistance, salt fog resistance, mildew resistance, but also has the very strong fast, friction resistance, solvent resistance and other properties, applicable to need often wipe machine and the machine work under the condition of the environment is bad.More valuable is silk screen white water signs of alumina production process, high efficiency, less basic no "three wastes", its human, energy (including water, electricity) consumption of no more than a third of the traditional corrosion sign.

       6.The printing aluminum oxide color plates of aluminum surface anodic oxidation plates is one of the signs varieties, which has been widely applied.It has a beautiful, bright, high hardness, good wear resistance, etc.Under the previous process for aluminum materials, mechanical polishing, chemical polishing, oxidation;Indirect silk screen version of the legal system, zinc barium Bai Hou paint alkyd varnish to protect printing;With dye printing ink staining.This process whether or dyed silk version, there are materials, complex process and low printing endurance, poor resolution, the shortcomings of high cost.Under the condition of existing technology, developed a set of working procedure is relatively simple, good quality, high efficiency of the new process is possible.New process with non-toxic type diazo photosensitive glue directly legal screen plate, proved to plate making fast, high resolution, high printing endurance, less material requirements.And protection paint, dyeing, printing can be printed material process combined into one, namely the self-made aqueous dye printing, direct dyeing, successive matching color, without color cylinder.Thus greatly simplifies the whole process and procedure, make the surface oxidation dyeing sign with the new method.
