The influence of extreme environment on the nozzle of pure cotton digital direct-injection T-shirt printing machine

The nozzle of the T-shirt printing machine is a sophisticated and delicate equipment, which is more sensitive to environmental changes, and is prone to malfunction in extreme environments, such as extreme cold, extreme heat, humidity, and more electrostatic dust. Environment, the nozzles of T-shirt printers are prone to failure. The temperature in winter will affect the operation of the print head. Winter is the worst season. The print head of the pure cotton digital direct-injection T-shirt printing machine is broken ink, because after the temperature decreases, the ink viscosity will increase as the temperature decreases. The increase in viscosity will make the ink fluidity worse, and the flow resistance of the ink in the ink circuit of the pure cotton T-shirt printer will increase. It is easier to break the ink during the printing process, and the nozzle will be more difficult to clean than the normal temperature. Most users think it is a problem with the nozzle or ink, but there is actually another phenomenon of 'false clogging'. Let me talk about the reasons for this. Influence of temperature After the temperature is reduced, the most common phenomenon is the 'false clogging' of the nozzles, that is, the 'disconnection' of individual nozzles. Because the same ink, the temperature decreases, the viscosity will increase, and the viscosity will be too high. Cotton T-shirt printers When printing at high speed, it is prone to 'disconnection'. The pure cotton digital direct-injection T-shirt printing machine used by many advertising companies will think that the nozzle is blocked, but once it is cleaned, it will be normal immediately. After a short time, it will repeat itself. Customers will think it is an ink quality problem. The second is the absorption and dryness of the ink. The temperature is too low, which is not conducive to the absorption of the ink by the inkjet medium coating, and it is also not conducive to the volatilization of the ink solvent. Cause the phenomenon of 'piling up ink'. The influence of humidity 'Dry' and 'wet' are measured by 'relative humidity'. 'Relative humidity' does not entirely depend on the amount of water in the air in gaseous form ('absolute humidity'), but also depends on temperature , When the 'absolute humidity' does not change, the 'relative humidity' will decrease when the temperature rises. The temperature is low in winter, regardless of whether it is heating or air conditioning, the relative humidity will drop-dry. Drying will cause the ink to easily condense on the nozzle of the pure cotton digital direct-injection T-shirt printing machine, causing the illusion of 'clogging the nozzle'; in addition, the dry environment is more likely to cause the material to warp, especially the PP paper, if you are not careful, it will be rubbed if you are not careful. The print head, in severe cases, will cause damage to the print head and motor of the T-shirt printer. The effect of static electricity and dust. Another result of the decrease in relative humidity is the increase in static electricity and dust. Static electricity is the top culprit that causes electronic products to burn out, because integrated circuits are most afraid of static electricity. Ten years ago, when computers had not 'flyed into the homes of ordinary peopleNowadays, in ordinary indoor environments, especially when air-conditioning and carpets are used, the static electricity in winter is particularly easy to burn the circuit boards and the nozzles of the pure cotton digital direct-injection T-shirt printing machine. Static electricity will also cause the degradation of print quality. Most inkjet media are 'insulated'. If T-shirt printers do not have good anti-static measures or do not have a ground wire, the ink droplets ejected will deviate from the direction due to static electricity, causing ' 'Flying ink' or 'splashing ink' phenomenon, the print quality will be seriously reduced. Dust, including fibers on the inkjet material, is also easy to adhere to the surface of the material, and under the action of static electricity, it further adheres to the surface of the nozzle, causing print quality problems. Dust affects the nozzles. To sum up, due to the weather and some physical phenomena in winter, the chance of damage to the nozzles of the pure cotton digital direct-injection T-shirt printing machine is very high. Therefore, we must take preventive measures and make sure to clean and clean the T-shirt printer. Maintenance, to ensure proper temperature (20-28 degrees) and humidity (40%-70%) in the working area, the service life of the T-shirt printing machine depends on the usual detailed maintenance.
