After silk screen printing, if the silk screen needs cleaning, the printing ink should be scraped from the image part of the silk screen to the bottom. Currently, the main methods for cleaning silk screens are manual scrubbing with solvent-based cleaning agents and using professional silk screen cleaning machines. Solvent-based cleaning agents are volatile, have a low flash point, and are flammable and explosive, posing chronic toxicity risks to the body when the high concentration of cleaning agent vapor in the air is inhaled, as well as posing a risk of explosion and fire. Some companies still use dangerous and highly polluting solvents like acetone without paying attention to environmental protection, increasing the risk of poisoning for workers. Water-based cleaning agents, on the other hand, can generally clean various types of silk screen inks, including drying printing ink (UV printing ink), quick-drying printing ink, self-drying printing ink, low-temperature heat-curing printing ink, and high-temperature ink.
Cleaning Silk Screens After Silk Screen Printing
During the printing process, residues such as printing ink, silver paste, and glue may adhere to the walls of the holes in the silk screen. Using a silk screen cleaning machine can prevent inadequate manual cleaning, which may cause residues to dry and solidify in the air, leading to deformation of the silk screen and interference with the demolding effect, thereby reducing the quality of subsequent printing. Silman Tech silk screen cleaning machines use a high-precision filtration system. The silk screen is placed manually into the cleaning chamber, and after adjusting the cleaning and drying time, the start switch is pressed, and the silk screen is automatically cleaned, rinsed, and dried. When the set time is reached, the machine automatically stops running. The door is opened for time reset, facilitating the next workflow. This greatly improves production efficiency. The liquid used for cleaning can be recycled in the machine, significantly reducing liquid consumption and costs, shortening working time, and eliminating the need for workers to come into contact with the liquid, thus avoiding harm to the body.

The application scope and interference of the silk screen cleaning machine DEZ-C742: Suitable for cleaning various types of silk screen printing plates, including silk screens, rubber screens, micro-mesh screens, and wafers. 1. During the printing process, printing ink, silver paste, glue, etc., may remain adhered to the walls of the screen holes. 2. After the printing work is finished, manual cleaning is insufficient to remove the residues in the holes of the screen, causing them to dry and solidify in the air, resulting in deformation of the holes. 3. Poorly cleaned silk screens will interfere with the demolding effect when reused, reducing the quality of subsequent printing.
