How to solve the rapid drying of CCD screen printing machine ink, let Zhengfei intelligent technology to tell you about it

　　CCD screen printing machine is widely used because of its characteristics of fast speed, high uniformity and precision

　　Do not attempt to use soy-based inks during the printing process, as soy-based is semi-dark (slow) oil, so it is not easy to have a dense appearance when printing dry on paper. The printing environment should be controlled within the 4.0 range with a pH of 5.0. The higher the acidity (the lower the pH), the slower the drying process will be. When printing for large areas of solid ground, use a desiccant containing varnish or overprint clear dimensions.

　　In use; Recommended amount of desiccant in ink. Too much desiccant will plasticize the ink instead of drying it. Adding additional boring agent to the wetting solution can improve the boring function of the ink. Boring agents can be used to increase the amount of 1, such as adding 2 O 3·R to the conveying end of the press, to keep the paper pile low. Large particles of dust are used to separate the printed paper, allowing more oxygen to enter and react with the oil and resin. Ask the supplier to increase the strength of the ink so that it can be printed with a thinner layer of ink that is easier to fix and punch. Because the temperature of the press or paper may be too low to delay the boredom of the ink, the paper should be pretreated before printing.

　　Under normal circumstances, the solution to control the drying speed of the screen printing machine brush ink, to reach an agreement with the ink supplier, to print things, what kind of ink supply is needed. After choosing good ink, pay attention to details to prevent small trouble. The oxidation rate can be increased by adding more oil or alkyd to the catalyst, or by using a fully passivated feedstock.
