The larger the negative pressure recovered by the printer, the longer the ink contacts the air, and the faster the solvent evaporates. The negative pressure generating device of the printer mainly recovers the vacuum gear pump separately, and separately recovers the diaphragm pump and the venturi.
The recovery pump of the individual gears in the three recovery modes produces the largest negative pressure, so the design of the separate recovery gear pump is the fastest solvent evaporation. Therefore, the design of a separate diaphragm pump is the most solvent-efficient.
Because the negative pressure of the diaphragm pump is not connected, it has a negative pressure generating frequency, that is, the negative pressure is generated every other time frequency, which greatly shortens the contact time between the ink and the air, so its volatilization is three designs. The smallest of them.
In order to achieve the same effect, the venturi recycling design is adopted.
PrinterIt is also possible to recover the ink by means of intermittent recovery by using the time-cycle closure of the solenoid valve of the recycling printer, which can also save the solvent evaporation of the printer.
The higher the ink temperature of the printer and the ambient temperature, the faster the solvent evaporates.
This reason is easy for consumers to understand. Because of any liquid material, the higher the temperature, the faster the liquid vaporizes. Like we boil water, water slowly begins to vaporize as the temperature rises, and the boiling point is the fastest.
The solvent of the printer is also the same. Its evaporation amount rises sharply with the increase of the ink temperature and the ambient temperature, and the solvent volatilization is proportional to the temperature in the first quadrant, and the solvent volatilization in the printer is Summer will be much bigger than winter.
