It has stronger control ability on ink droplets, and the amount of ink ejected by this technology is only 1/3 of the usual amount, and the minimum amount can reach 2pl. Moreover, the shape of ink droplets is more regular, the positioning is more accurate, the printing resolution is improved, and it is easy to realize high-precision printing. In addition, there is no need to heat the micro-piezoelectric ink jet, and the ink will not change chemically due to heating, which reduces the requirements for ink. Due to the continuous stability of temperature, The viscosity and surface tension of the ink can be kept relatively stable during long-term uninterrupted continuous jet printing, so as to ensure the consistency of print quality before and after, and the uniformity of color reproduction of customers' repeat order-. Some people use anti-corrosion technology to make water-soluble inkjet printing tests on hot bubble and ceramic piezoelectric inkjet printers. The average life of hot bubble nozzle is about 8,-1, ml, which needs to be replaced, and the average life of ceramic piezoelectric inkjet nozzle is about 5,-1, ml. From the above data, we can see that there is a great difference in economic benefits between the two inkjet printing methods. < P > Due to the high patented technology, In the micro-piezoelectric ink head, the nozzle and the ink cartridge are separated structures, and one nozzle can support multiple ink cartridges. When replacing ink, only the ink cartridges need to be replaced without replacing the print head. Of course, after the ink head of the piezoelectric inkjet printer is blocked, a lot of ink has to be wasted to clean the ink head. Every time the ink head is replaced, 3% of ink should be wasted for ink head cleaning, and it takes 2 ~ 3 minutes to clean every time the machine is turned on, and some ink should be wasted. When the gas meter requires the user to replace the ink cartridge, there is still 17% ~ 25% ink left.
The inkjet printer of Epson Company is the main one that uses piezoelectric inkjet technology. Many special industrial inkjet printers mostly use ceramic piezoelectric inkjet technology.
