Electrostatic reaction will inevitably occur in printing operation, which will affect the printing effect. How to solve the electrostatic phenomenon in the process of making Jinan ink-jet photo? Let's share the following points for you, hoping to help you.
一般在秋季和冬季,空气中的湿度随季节的变化很明显下降,甚至一些地区湿度要小于20%,导致严重的静电现象,在印刷前喷墨墨滴的操作灯箱布,方向改变导致粘贴头现象。如果长时间不解决这个问题，打印机的静电电压会达到6 ~ 10V，很可能会对喷头造成损坏。因此在发现静电现象时应及时解决，不能拖延。
Generally in autumn and winter, the humidity in the air decreases obviously with the change of seasons, even the humidity in some areas is less than 20%, which leads to serious electrostatic phenomenon. Before printing, the operation of light box cloth with ink-jet drops, the change of direction leads to the phenomenon of sticking head. If this problem is not solved for a long time, the electrostatic voltage of the printer will reach 6 ~ 10V, which is likely to cause damage to the nozzle. Therefore, the static electricity should be solved in time without delay.
1、必须认真对待接地问题，主要做法:将0.5m2的铜板焊接好4mm2的铜线埋在地下1.5米的潮湿土壤中，并浇上盐水。地线采用整条线，无接头，与机器良好接触。本机周围湿度达到40 ~ 60%相对湿度。这样，PVC灯箱布摩擦产生的静电也会从空气中传播出去，不会影响喷嘴上的墨滴。工业加湿器的标准是每小时消耗不少于4升水。如果你有良好的通风，选择一个每小时消耗6升水的加湿器。另外，有些客户使用喷枪和压缩空气加湿器效果也不错。
1. The grounding problem must be taken seriously. The main method is to weld 0.5m2 copper plate with 4mm2 copper wire and bury it in 1.5m wet soil underground, and pour salt water. The ground wire shall be the whole wire without joint and in good contact with the machine. The humidity around the machine reaches 40 ~ 60% relative humidity. In this way, the static electricity generated by the friction of PVC light box cloth will also spread out from the air, without affecting the ink drop on the nozzle. The standard for industrial humidifiers is to consume no less than 4 liters of water per hour. If you have good ventilation, choose a humidifier that consumes 6 liters of water per hour. In addition, some customers use spray guns and compressed air humidifiers to achieve good results.
2. Selection of light box cloth: the surface roughness of light box cloth directly affects the generation of static electricity. Try to choose the light box cloth with low calcium carbonate content and smooth surface. Try to keep the temperature constant 3. Use electrostatic brush to solve static electricity. Or in the operating room for air exchange, pay attention to the temperature and humidity changes.
4. Using high viscosity ink, the antistatic effect will be better. The principle is that the larger the weight of ink droplets, the smaller the influence of static electricity, but the influence of high viscosity on the piezocrystal of nozzle needs to be explored.
