Ming-color screen printing ink on the signs, painting selection panel of three high-quality epoxy resins and International Group agency's 1300 series and 1000 series two-component metallic inks, because the choice of two ink. In addition to their high adhesive strength, but also has a very high surface hardness and brightness, and can resist a variety of chemical cleaning agents wipe clean the panel, so the two coexist ink can paint on the panel and never separation and loss. But we must use the correct process uses two ink in order to achieve the effect deserve. Features 1,1300 series Screen Printing Ink: 1) Ink in the manufacturing process have been previously added to the catalyst (to retention agent) one-component thermosetting type ink, which is characterized by screen printing after drying standard temperature 150 ℃, and drying time and size of the workpiece material and the layer thickness is related large parts area, thicker, longer drying time is required ≥30 minutes of drying time under normal circumstances; when the set temperature> 150 ℃, then dried corresponding to the time can be shortened, the drying temperature as much as possible not less than 150 ℃, otherwise there will be: a. Not completely dried, as a curing agent to reach a certain temperature curing poor; b. Not completely dried, imprinted poor adhesion, even not strong; c. Not completely dried, the surface brightness difference, do not wear, organic solvent wipe will fade; 2) found that under the right conditions of printing screen printing process, said quality problems after drying that: ● regulate the viscosity of the ink is not, in general, Under special solvent T - 1000 (10: 1 ~ 1.5 preparation); ● storage at high temperatures much higher than the validity of the ink-blocking, for dissolving the poor; ● stored at room temperature within the validity period, the ink is affected by the outside air, which reducing the catalytic performance to curing agent (catalyst), it should add 1% of catalyst 1300H adjustment reuse. 3) Color printing should be noted that each print one color need low temperature (such as 100 ℃ × 10 minutes) and dried, as long as sticky then, after the last one color screen printing should be> 150 ℃ under completely dry; overlapping color printing should also comply with this rules, otherwise every color bake until completely dried, there will be less interlayer adhesion prison. It is worth noting, screen printing color panel painting, paint layer panel screen printed on the front panel should reach below 100% dry solids, or spray paint surface crystallization, affect the color of the ink and baking firmly attached, when screen printing the last one color after drying of the ink at the same time, the panel of the paint to dry completely. 4) If the standard plating for both brand-name protection blotting, and is a permanent network of decorative patterns printed color inks, the PH value of the plating solution should be> 3, for example, nickel plating on non-color screen printing color signs pattern part, decorative gold plating solution, its PH value = 3.8 to 4.6. 2, features a two-component screen printing ink 1000 series: 1) prior to the deployment of two-component ink used is correct or not, the decision to ensure the design property of the ink, and therefore the deployment of the right, in order to ensure the quality of the two-component screen printing ink after requirements, we must pay attention; the correct ratio 2) Seiko 1000 series two-component screen printing ink and hardener common primary agent 7: hardener 3 ratio screen printing after this deployment, cured hardness up to 3H, the frictional resistance to alcohol , alkali resistance and can be wound is also good. Of course, the main agent and hardener ratio requirements of the workpiece can be adjusted based agent 6: hardener 4, screen printing ink after coilability particularly good, but the other two properties, particularly alkali resistance on the bad. 3) the deployment of important ways: First, the main agent of the ink should be stirred after full access, strict proportion to the scale to take the mixed ink main agent and a hardener and stir evenly, then after 10 minutes of curing time before by supporting a special Solvent T-1000 in accordance with the 10% to 20% to be adjusted to a viscosity suitable for screen printing. If the order to deploy the mistake, it will affect the curing properties and ink film unite characteristics. 4) After a two-component ink properly formulated, generally refers to more than at 20 ℃ touch dry in 2 hours, hardened to over 30 hours, with the placement growth over time, the patience, the better, naturally white paint drying on the panel, treated PE, PP label more appropriate for after screen printing of metal parts can also use the 80 ℃ ~ 120 ℃ drying curing. 5) Screen Printing amino painted panel, please note that in order to ensure that the ink and paint adhesion, when drying less impressive prepress network painting panel dryness, to prevent the paint produce crystallized until the color screen printing ink at 120 ℃ Under dryness amino baking while also completely dry solid, which is to ensure a two-component ink can be high and hard, amino baking surface luminosity firmly attached key. More than two inks can also be directly printed on net iron, aluminum, stainless steel plate, so just above process operation, one must possess the characteristics of a color screen printing Ming, signs, paint the panel on the show in front of this network printing process has been successfully used on maritime military products, instrumentation, equipment, and electronic equipment.
