Throughout the year, the climate is different in each season, so how to maintain the printing machine is not the same in each season. The printing machine is well maintained in order to extend the life of the printing machine and create more high profits. And in summer and autumn is the most easy to produce static electricity season, so how to prevent static electricity digital printing machine?

Static electricity is an electric charge that is at rest or does not flow (flowing charges form an electric current). Static electricity is formed when the charge gathers on an object or surface, and the charge is divided into two kinds of positive charge and negative charge, that is to say, the electrostatic phenomenon is also divided into two kinds of positive static electricity and negative static electricity.

Static electricity is generated in three ways:

1, friction: any two objects of different materials after contact and then separation, can produce static electricity.

2, induction: for conductive materials, because the electrons can flow freely on its surface, such as placing it in an electric field, because the same sex repulsion, opposites attract, the positive and negative electrons will be transferred.

3, conduction: for conductive materials, because electrons can flow freely on its surface, such as contact with charged objects, charge transfer will occur.

Digital direct injection molding machine is a widescreen printing device that relies on computer control image output, its core components are various motherboards, the internal circuit gap is short, the area is small, the sensitivity voltage is generally between 0-200V, it is easy to fail due to static damage.

There are three main methods of controlling static electricity:

1. make the printing material ground;

2. use electrostatic coating or cleaning agent, etc.;

3. Make the air around the material with static electricity ionized.

However, in practical operation, making the material grounding is not realistic, the use of antistatic coatings and cleaning agents inevitably greatly increase the cost; Ionized air also has many inconveniences, in order to do scientific antistatic at the airport:

A. Control the printing speed. Research shows that after the speed is reduced, the electron cloud is in a stable state, the electron will not be released, and the probability of generating static electricity is lowest.

B. Control room temperature and humidity. In general, within the 40%-60% relative humidity range, static electricity on the printing material is easier to be transmitted and removed without affecting the ink droplets on the jet nozzle, ensuring printing accuracy. It is recommended that the office space regularly open windows to breathe, to ensure good ventilation.

C, for the digital direct jet do good grounding work. When burying the ground line, first dig deep into the ground 1.5 deep, if the excavated mud is wet, use 0.6 square copper wire, it is best to tie a piece of iron, use a whole line, no interface, then bury deep, and pour salt water.

D、Do not use high viscosity ink。Although the ink droplet weight is too large can reduce the electrostatic effect，But the viscosity is too general to the direct jet nozzle head crystal brings disadvantage。
