The traditional manual cleaning process for screen printing screens involves dipping cloth strips into cleaning solution or anti-white water for scrubbing, typically cleaning one side before proceeding to the other. However, this process poses several challenges and issues:
- Due to the subjective nature of human operation, there is a high risk of damaging the tension of the screen, even leading to screen breakage.
- Residual printing paste in the tiny mesh of the screen image can lead to poor printing results and render the screen completely unusable after the paste solidifies.
- Small local areas in the screen image are prone to causing photoresist peeling, resulting in poor printing results and rendering the screen completely unusable.
- Prolonged exposure and inhalation by operators can lead to occupational diseases, affecting occupational health and safety. Common occupational diseases among screen room workers include leukemia, skin ulcers, delayed reaction times, gastrointestinal ulcers, respiratory diseases, dizziness, sudden bleeding, and limb weakness.
- Environmental pollution occurs due to the exposure-based cleaning method, with chemical agents evaporating into the air. When the concentration of cleaning agents in the washing area reaches a certain level, it can lead to fire, explosion, and other safety accidents. Even a small spark can cause a fire or explosion.
- Generation of a large amount of hazardous waste. Used cloth strips, due to their absorption of ink and chemicals, become hazardous waste that significantly pollutes the environment and cannot be casually discarded. Professional hazardous waste disposal companies need to handle them, incurring high disposal costs.
Many companies have been aware of these issues for many years, especially those that prioritize quality and employee health. They have already purchased professional screen cleaning machines like the DEZ-C730S Screen Cleaning Machine. This machine features full pneumatic control, eliminating the risk of fire and explosion. Its enclosed cleaning process prevents personal injury and environmental pollution. The 360° dual-side equal pressure rotating jet cleaning ensures unclogged mesh and consistent screen condition before and after cleaning, preventing photoresist detachment and improving printing quality.
