Photosensitive acid secondary oxidation Ink: XR-3700

 Photographic developing acid secondary oxidation has clouded ink XR-3700 in order to reduce the adverse effects of waste electronic products shell on the natural environment, the world require the manufacturer for recycling waste materials for their products. Therefore, its light weight aluminum and aluminum alloy, does not rust, heat quickly, the characteristics of renewable reusable, it will be the best material appliances, mobile phones, computer housing. On aluminum and aluminum alloy shell surface through etching process to produce a secondary coloring needs of a variety of fine patterns, the company specifically for the characteristics of aluminum and aluminum alloy developed a strong ability of acid alkaline chemical solution in high resolution rate sensitive developing ink. Operation process and technical parameters of ink: the ink main agent and curing agent were mixed 83:17, stir for 10-15 minutes, adding a suitable viscosity thinner adjusted (screen 60-100dpa.s roller or spray 10 ± 5dpa.s, within 25 ℃) 48 hours of mixing run. Coating: to use screen printing, roll coating, spray coating, etc., coating shop requires good ventilation, ambient temperature ≤25 ℃, humidity ≤75%, the light is yellow, the coating thickness (after drying) 15-20um . The coating good piece Bays placed and oven or other drying apparatus under predetermined conditions (75 ℃ ± 5 ℃, 15-25min) pre-drying. Good pre-drying ink is adhered to each other, and thus the workpiece can not pack. Exposure and development: exposure gradient control in 7-9 foot cell, NOTE: requires the operating environment for the yellow light before development. After developing the graphical workpiece easily scratched, so the need to separate the workpiece Bays placed or stacked with plastic pads are separated.
