Screen business card printing and membership card making static control

Now wire system cards and membership cards used in the production of printing conductive materials have increased a lot. Some commonly used conductive materials, printing cards and card production system, workers must be very clear on the importance of controlling static electricity. Understanding of electrical knowledge, to master static knowledge, know how to avoid or reduce static electricity, the system cards and membership cards will produce improved quality.

Typically, humidity, grounding, static neutralization, scraper speed / system cards and membership cards produced intermittent time, wire tension and the network distance is effective to reduce or avoid the static factors.

First, the concept of static

From the perspective of atomic science, plastics, paper and other materials are usually neutral. Each atom with the positively charged nucleus surrounded by negatively charged electrons and the clouds. When the two materials, either through pressure or through frictional contact after the separation of electronic materials will be free surface, resulting in static area. Electronic decrease was positively charged surface, whereas with excess electrons were negatively charged surface, these two materials will be charged with the opposite charge to attract the material around to make the electrical properties of and, if the charged material is conductive, then the electrostatic the Netherlands will soon be transferred to the ground through the material, if the material in the system, making cards and membership cards in the live, the electrostatic charge will be transferred to the plant surface. If the material is an insulator, the electrostatic charge in a few hours, weeks or even months and then gradually left out.

Low humidity can easily generate static electricity, because the majority of surface moisture, if there will be a certain conductivity, ambient humidity increases, conductivity increases, thereby reducing the static electricity. Usually in the winter or air-conditioned room, because to reduce humidity, prone to static electricity.

If a factory working environment to reduce static electricity, it is best to install humidity and temperature control equipment, which not only effectively control static electricity, and can reduce or eliminate the system all affect the quality of cards and card production factors.

As the environmental conditions throughout the plant control the same, membership cards will be made to reduce the preparation time before, in the constant humidity and temperature, the system cards and membership cards will be produced to a certain known ink speed of evaporation, this will reduces the system card and membership card production and drying of many uncertain factors.

According to the survey indicated that if the work environment is comfortable, stable, and the employees will get better performance, less operating errors. Some problems caused by static electricity, even though the same kind of material, due to the system card and membership card making machine at different speeds, their performance are not the same, sometimes almost no Reasons to be a problem.

Each paper separately in a minute, and then fold together. Since plastic is a very good insulating material, so it static sensitive.

Problems caused by the static electricity, mainly in the following expression:

● scraper after the departure of agglomeration ink in the Web version, stick together;

● printing material affixed together, and can not be separated;

● printing materials can not laminated together, or almost can not pile up;

● printing material paste in the bottom of the screen version;

● Fully automatic system cards and membership cards can not properly feed making machine;

● operatives electric shocks.

Second, static eliminator

Some static eliminator to make use of metal grounding electrostatic charge neutralization. The two most commonly used conductive metal foil and brush.

Static Eliminator is produced in the air positively charged and two negatively charged ion, when any static electricity through the body from here, the corresponding oppositely charged ions with one and eliminate static electricity.

With the power of the static eliminator bars formed by the power and anti-static, anti-static bar of arbitrary length can be customized to the manufacturer, generally the length and the width of the same material to be processed.

Surface to eliminate static electricity has been very easy to get rid of dust, because dust and static electricity will not re-adsorbed to the surface.

Now whether the market has shaken Ionizer, especially when a transmitter as stained with dust or wet ground accident, while anti-static bar is still working, this device is very effective to eliminate. There is a conductive brush use of the existing electrostatic voltage ionization of air molecules, which normally produce high static voltage of high pressure in a fast-moving surface, such as high-speed movement of the scraper under the pressure of polyester mesh surface will electrostatic voltage.

Another type of static eliminator vessel to eliminate static charge within the specified range.

Third, the system cards and membership cards produced on multi-control methods used in static

Now common, basic control static methods are available as follows:

● to make the material static electricity grounding;

● Use anti-static coating / cleaning agent;

● to make the material with the surrounding static air ionization.

1. So that the material with electrostatic grounding is not practical as it is impossible to make contact with material objects in general and the ground, such as metal cards and membership cards production units, when the printing material and the ground object separated, will generate static electricity. Therefore, this method only if the printing surface humidity of 60% to 70%, with electrical conductivity, make the system cards and membership cards make sense in the context machine ground.

In a clean environment can also use other grounded object, such as conductive floor mat / pulley, conductive mat, on the sole ground sinks.

2. Antistatic coating / cleaning agent is mainly coated with a charge in the graphic area, where electrostatic charge generation is a major problem. Antistatic coatings, hydrocarbon chloride solution, highly volatile, with low metal ion, particle concentration is low, polyethylene, stainless steel, pVC material or plastic coated surface without damage.

Despite the apparent effect of anti-static coating, but not practical, because the paint is expensive, but also in the Photo Department or the device requires repeated coating anti-static coating. Anti-static coating by reducing surface friction, so that charge flows to the surface, while reducing material capacity to generate electrostatic charge. Most anti-static coating is non-corrosive and non-flammable.

3. Ionized air molecules to oxygen molecules in the e-free, resulting in negatively charged electrons, and positively charged oxygen ions. If the material with a positive charge, may be negatively charged electrons in and; the contrary, if materials with a negative charge, it can be positively charged and the oxygen ions.

Ionizing air molecules into a power supply, no power and nuclear and in three ways. And use of radioisotopes in the launch of nuclear particles, ionizing the air molecules. Such particles are mainly shorter wavelength, can easily be absorbed by oxygen molecules α-particles, α particles and oxygen molecules colliding oxygen molecules to separate nuclear and electronic. Radioisotope to launch tens of thousands of α-particles per second, each α-particles in the very short stroke can induce thousands of ions, the positively charged oxygen ions and the electron dense layer of clouds. The advantages of nuclear and in need of additional power from one machine to another machine to use, it is very suitable for the case of flammable solvents used.

Nuclear and electrostatic Horry used in the element polonium, this method has an obvious inconvenience is to make the surface and in the distance and the device 1 ~ 1.5in (inches) between.

Screen system, making cards and membership cards to use a brush, but also in the use of nuclear and electrostatic principles. Hard surface in the brush upload a polonium-chip, will reduce the electrostatic charge, but also dust, hair removal and other particles.

4, screen system tension and speed of cards and card production

Wire tension and the system card and membership card production rate of two variables is often ignored.

Scraper system, making cards and membership cards reduce the speed, the electronic cloud around the nucleus in a relatively stable state, but even the system of cards and membership cards produced slow, scraper pressure is too large, the nucleus around which would be in non-electronic steady state, electrons are separated out under the pressure of the scraper, static electricity, so only when the scraper system, making cards and membership cards slowly while the pressure for the case of scraper, to avoid static electricity generation.

Wire tension is considered a successful system cards and membership cards produced key factors to reduce the network distance and scraper pressure, thus avoiding friction, thereby reducing static electricity.

Screen system, making cards and membership cards industry, affecting the system static card and membership card normal production of the main factors, because the static electricity to make the system work produced cards and membership cards to maneuver, but also creates a fire hazard.

A system of cards and card production plant if temperature, humidity control or not control will not produce static electricity, making the system fully automatic production machine cards and membership cards can not be resumed normal paper, not high speed. For each different plant is difficult to say what kind of equipment is suitable, can effectively reduce static electricity, static elimination equipment sales please contact the company, ask them to look at your plant, check the causes of static electricity, and purchase of equipment to eliminate static electricity .
