Nozzle as an important accessory of the photo machine, in the use of the process sometimes there will be nozzle blockage phenomenon, nozzle blockage will affect the picture quality of the photo machine, so how to prevent nozzle blockage?
So let's first look at a few factors that cause the nozzle to clog up.
Photographic machine nozzle piezoelectric crystal damage factor
Piezoelectric photo machine mainly rely on the physical changes of piezoelectric crystals to control the inkjet process, and a photo machine nozzle service life should be more than one year, roughly can print 20000㎡, if the long time overload operation, internal components tend to wear large and destroyed. Photo Machine piezoelectric crystal fatigue damage phenomenon is the nozzle sometimes inkjet, sometimes can not spray ink, especially in the large amount of inkjet (that is, when spraying dark screen) "blockage" phenomenon is obvious, at this time the best way is to replace a new nozzle
2. Filter blockage factors
Outdoor Photo machine Oily ink is generally made of pigment as raw material, its granularity is large. Nozzle internal filter blockage caused by the nozzle does not ink, the use of a longer time nozzle, especially in the Inkjet machine inkjet task is not full often night shutdown of the factory, ink in the nozzle does not flow for a long time, easy to adsorb in the internal filter or ink wall, so that the ink flow of the cross-sectional area will also cause the nozzle ink phenomenon.
3.ink reason
The compatible inks used by different photo machines are also different, and the materials used in the ink produced by different manufacturers are different. In order to speed up the printing speed of the photo machine and make the ink fast drying, ink manufacturers will often add related desiccant and so on, some manufacturers of ink due to improper control of the amount of desiccant, drying too fast, easy to cause ink in the external blockage, although it can be cleaned, but the time interval for cleaning is more frequent, Once the nozzle is not used for a long time and the nozzle is not protected in time, it may cause permanent damage to the nozzle the next time the painting is sprayed. Therefore, it is your wise move for users to choose high quality original ink.
4、The use of the photo machine environment on the nozzle is also very large, we know that the temperature is different all year round, the environment makes the ink viscosity increase or decrease, the viscosity is too high liquid fluidity is worse, the amount of ink ejected per unit time is insufficient, and the viscosity is too low and easy to lead to the piezoelectric crystal back suction air, air burning problem. Therefore, summer attention to the ink cooling, winter attention to heat preservation is very important. In addition, the working environment of the photo machine power supply voltage, electrostatic protection, human misoperation and other factors will be easy to cause the photo machine nozzle damage, but also pay attention to.
