When cleaning the screen of the polyester printing mesh, many people will ask how to wash. In fact, there are still many ways. But the ultimate goal is to clean the screen. Maishi's professional manufacturer of polyester fiber printing meshs told us that it can be noted that the water is washed with tap water, and the oily water is washed with net water or cyclohexanone. The specific cleaning method is as follows:
If the polyester printing screen is not cleaned immediately. It is necessary to scrape the ink from the image portion of the screen to the bottom of the screen, and use a wet sponge to scrub the screen image portion, and if necessary, use the screen cleaner to clean the image portion to prevent the ink from drying on the screen. Finally, the ink is collected and played back into the ink tank. If some of the non-images of the screen are still left with ink or dirt, this will not affect the printing effect, and all the dirt on the screen will be removed during the screen recycling process.
The method of cleaning according to different application scenarios is also different.
For example, the cleaning method used in the screen cleaning method of the circuit industry will be somewhat different, because the raw materials printed on the circuit will have a small amount of sodium thiosulfate and a small amount of silver complex, and the residual raw materials can be removed by washing with water.
The advantage is that the use of the screen is prolonged, avoiding the color of the film that has been left behind due to special changes and chemical reactions. The commonly used method is to wash by water, but some of the raw materials used in the printing process cannot be removed by using the method of washing. The other materials must be used for cleaning or sprinkling. When the printing is completed, the plate should be cleaned immediately with the corresponding solvent, and no ink should be left to prevent the residual ink from drying up and blocking the net.
Professional screen printing meshs require long-term use, which requires the necessary cleaning methods. Careful and careful can ensure the long life of the screen printing mesh.
