People who have worked in Jinan calendar printing company all know that there will be powder falling in the printing process. What is the phenomenon of falling powder? Falling powder refers to the phenomenon that a large amount of dust generated by the vibration of the machine gathers on the surface of the printed matter during the operation of the printing machine, which makes the printed matter very ugly.
It is easy for dust to adhere at the nozzle of dispersant and the nozzle connecting the nozzle. The whole press has up to eight nozzles. Both sides of the drawer. When the elevator falls, the dust on the track is easy to attach and fall. The more paper piles up, the more easy it is to fall large pieces of dust.
How to solve this problem? The development of cohesionless mechanical powder spraying is not a simple operation, and the complete treatment of powder surface is impossible at that time. At present, there is no best way to deal with powder surface except for cleaning machine.
After cleaning with air gun, Jinan calendar printing company seems to have no dust, but the powder will fall in the printing process, so the cleaned printer idles for 5 minutes at high speed, making the dust fall completely; together, the glass lining can not adhere to the dust. The cleaning times are related to the printing time, once a day; if it works 24 hours a day, twice a day. In addition, PP coating, subsequent treatment, in order to be careful, first cleaning, control the amount of dispersion.
