There are no perfect people in the world, so most people will always make mistakes or encounter some problems in life or work, but this is not unsolved, just like screen printing machine users, may be in daily use You will encounter the problem of blocking the screen printing screen. Today, I will analyze the reasons for the blocking of the screen printing screen of the screen printing machine. First of all, starting from the screen printing screen of the screen printing machine itself, a good screen printing screen must be rinsed with water and dried before use. In addition, it may also be the problem of the substrate, because the materials of silk screen printing are various, and the substrates of different materials will also cause the phenomenon of board blocking. Users need to consider this factor.
In addition, due to the excessive pressure during printing, the scraper did not scrape the ink cleanly, resulting in the ink remaining on the screen of the screen printing machine and not completely leaking to the substrate. If the intermediate machine is suspended for a period of time, it may cause the ink conjunctiva. Blocking phenomenon. Of course, it may also be caused by temperature. Generally, a stable temperature and humidity should be maintained around the screen printing machine when printing. If the temperature is too high, the ink solvent will evaporate too quickly. If the temperature is too low, it will also cause the ink to have poor fluidity and stick to the screen printing. online version. In the end, it is because of the ink. Generally, if the ink dries too fast, it is easy to cause the phenomenon of blocking, especially when the ink selected by the user is a drying ink, so the user needs to choose the appropriate ink to use, and when using When the ink is solvent, the drying speed can be controlled to ensure that the ink will not dry too fast or dry too slowly, resulting in the phenomenon that the ink adheres to the screen printing screen. If the screen printing machine encounters a blockage problem during use, I think most of these are the reasons, so you can find solutions from it.
