6, drying conditions:
①1R far-infrared tunnel oven: 180 ℃ 10 min for full drying.
② thermostatic oven: 150 ℃ 20 min for full drying.
③ ordinary tunnel + thermostatic oven: first baking tunnel oven 150 ℃ -170 ℃ 5 minutes the surface is dry, the last time the printing baking oven 150 ℃ 20 minutes after completion, to dry completely.
7, pay attention:
① the ink formulation amount of curing agent must be weighed accurately; first curing agent and a diluent uniformly mixed, then add it to the appropriate amount of crude oil, using a small mixer (1000 / h speed), stirring 3-5 minutes, The ink was allowed to stand for 10 minutes, then screen printing. Ink printing environment 25 ℃ ± 1 ℃, humidity of 50-65%.
After ② ink printing is completed, please let stand for 10 minutes before baking, let stand for leveling ink well, to avoid the appearance of pinholes and trachoma.
③ ink in the printing process, every hour of adding a new deployment of good ink, or the appropriate amount of diluent to keep the ink in printing fluency.
6, the ink storage conditions:
① ink at a constant temperature 25 ℃, air humidity of 45-65%, sealed and stored away from direct sunlight. Original sealed shelf life of 12 months.
② curing agent at a constant temperature of 25 ℃ air humidity 45-65%, sealed and stored away from direct sunlight, sealed the original retention period of six months.
VII Note:
① When the ink formulation, when crude oil is not used, please sealed to prevent solvent evaporation, curing agent immediately after taking sealed to avoid moisture absorption curing agent.
② before printing inks, make sure the surface of the substrate table has dust or static electricity, and to ensure that operating in one thousand or 10,000 clean room environment.
When the ultrasonic cleaning ③ white glass, the temperature control 70-80 ℃, final cleaning mist for 3-5 minutes slowly pulled glass shelf, avoid remaining traces of water droplets caused by printing different colors on the glass.
④ washable ink or screen with a 783 clean, such as ink adhered to the skin, please wash with soap and water, eating or feeling uncomfortable consult a physician immediately.
Please use high-pressure water, dry mist, carbon dioxide, foam or dry chemical fire isochronous ⑤ out the fire, other features, refer to "MSDS".
NOTE: Description and data in this technical data within the company are technical engineers by many years of research and believed to be accurate, but it does not mean that when the ink use can get the same effect, because this information is based on technical engineers test environment was developed, So when customers use inks should be workshops and operating conditions, after the actual test print and determine suitability.
