The main factors leading to broken gates can generally be summarized as: personnel, machinery and equipment, materials, methods, environment and other issues. Add preventive measures in these areas to improve the sense of responsibility of the operators, strictly implement the operating specifications, control the temperature and cleanliness of the workshop, and properly add some auxiliary equipment. Help solve the problem of broken gates.
However, the above reasons are only macroscopic and need to be gradually improved during the operation. During operation, sudden breaks in the grid often stall production, and at this time, how to deal with emergencies becomes very important. Some netizens have identified several specific problems that have caused the grid to break: First, the silver paste and the screen are not matched. Different types of silver paste are different in viscosity, so there is a matching problem with the screen version. Silver paste If the viscosity is large, the screen thickness of the screen cannot be too thick. Secondly, it is not enough to see if the fine line tangent line edge of the screen is sufficiently smooth.
In response to the above answer, a certain printing process department gave specific emergency measures. They told the printing user that when a broken gate was found, the printing was immediately stopped, and the plastic ink-knife was used to dip the slurry and gently shoveled the screen grid, and then used clean. The dust-free cloth wipes the screens along the fine lines. For the new screen version, the operator can appropriately reduce the printing speed, increase the pressure, and adjust the printing parameters after the printing is smooth. When the slurry is stirred on the drum, the heater is placed to increase the fluidity of the slurry, but the temperature cannot be too high, 30 degrees is appropriate, and the temperature is too high will affect the height of the printing grid line.
Taking into account the ecological environment and economic benefits
The screen has also taken many measures in environmental protection. For example, with the extensive promotion of free processing plates, the prompt release of exempt CTP products. After exposing these plates without treatment, they can be developed without the use of chemical agents and increased power. The screen also provides hybrid screening technology to reduce the amount of ink used during printing. In addition, the environment is a major factor to consider when publishing the God 8000N R&D, so the publication of the God 8800N-S output can save a significant 28% of the power for each plate.
"Every new product development period, the screen will use environmental assessment as a necessary content to consider whether the product design is feasible." Yonezawa Yubo said.
