I didn't notice it during the printing process. It was a headache when I found that powder dusting accidents occurred after printing or after processing.
Reasons for falling powder:
The term "dropping powder" refers to the phenomenon that dust adhering to the printing machine vibrates during the operation of the machine to cause dust agglomeration to fall on the surface of the printed matter.
Where the flying dust is easy to adhere
The spout portion of the spreader and the nozzle around the spout. There are eight outlets for the full press.
Inside and around the electrode of the antistatic device that is placed side by side with the paper discharger.
A part of the small fan of the paper discharger and the surrounding.
The two sides of the lifter of the paper discharger. When the lifter is lowered, the track tends to adhere to the dust, and the more the paper is piled up, the easier it is to drop large pieces of dust.
In short, it is not a simple matter to solve the problem of the residual surface of the printed matter caused by the powder, and it is not easy to develop the powder that is not easy to adhere to the machine. There is no best way to solve the problem of powder drop, except for cleaning machinery.
Cleaning place:
Around the spout;
Anti-static pipe;
Fans and paper dischargers everywhere;
The two sides of the lift.
Use an air gun and brush for cleaning.
After cleaning with an air gun, it seems that there is no dust but it will fall off during printing. Therefore, after cleaning, the printing machine idling for five minutes at high speed, so that the dust completely falls off. At the same time, the glass around the paper discharger can be adhered to dust. . The number of sweeps is related to the amount of print time spread, once a day; if it is continuously operated for 24 hours, twice a day. In addition, in the case of PP coating and subsequent processing, in order to be cautious, cleaning is first performed to control the amount of dispersion.
Avoid the powder, inhibit the flying, use a small amount of powder to solve the back printing, and easy to clean the hydrophilic UP800 is our recommended.
