The cost spent on buying one set of DISK electrostatic Coating Machine. With some investment, you can cut off huge costs required for paint and the technician while increasing your production and improving product quality. Abiding by human-based spirit, the ultimate goal of manufacturing the DISK Electrostatic Automatic Coating Machine is to efficiently use the energy, improve the quality and protect the environment.

Our equipment of liquid electrostatic coating can significantly improve the coating quality and production while reducing the paints consumption, the waste discharge and the maintenance cost. Because of the highly atomized live paint grains, the film is uniformly and smoothly coated on the workplace which has reduced the orange tissue effect and improved the coating layer quality.

Liquid Electrostatic Spray Coating What is DISK electrostatic coating?

In using the DISK electrostatic coating equipment, the high revolution of

DISK tends to throw the paint away when the paint passes through

the live DISK. In this case, the expelling effect appears between the

paint carrying electrostatic and the live particles as to cause further

atomization of paint and thus, forming much finer thin fog. Due to the

occlusion of electrostatic, the lost paints are sucked back to the

workplace in generating a kind of surrounding electrostatic effect and

the over spraying phenomenon is thus minimized. In this way, the

machine has achieved the purpose of electrostatic coating.

Why DISK electrostatic coating?

The DISK electrostatic coating can significantly improve the spraying

quality and production while reducing the paint consumption, the

waste discharge and the maintenance cost. Because of the highly

atomized live paint grains, the film is uniformly and smoothly coated

on the workplace which has reduced the orange tissue effect and

improved the coating layer quality.

Advantages

Transfer efficiencies range from 85 % to 95 %

Excellent edge coverage is achieved because electrons are attracted more strongly to edges than to flat surfaces

The attractive forces of electrostatics will to some extent draw paint droplets around to the back side of the parts, a phenomenon called wraparound or wrap

As coating thickness builds, it forms an electrically insulating layer. Additional paint droplets are attracted most strongly to areas on the part where grounding is best, that is, the spots where paint is thinnest, result in a more even film thickness

OTSON Technologies Corp was established in 1984.With over 20 year's experience in electrostatic coating equipment and products precision machine in Taiwan. OTSON consistently endeavors to invent and develop the advanced products to meet the newly trends on the surface coating markets.

Surface Technology Overview of Electrostatic Painting and Coating Technologies

The principles of electrostatic charging apply equally to liquid and powder coatings. In electrostatic coating, the fluid is atomized, then negatively charged to the object, thus having a less negative charge than the paint. Increased transfer efficiency is achieved, up to 95%. For instance, it is possible to spray paint a cyclone fence electro statically with fair transfer efficiency. Both sides of the fence can be painted from only one side due to the electrostatic attraction. Atomized paint droplets are charged at the tip of the spray gun by a charged electrode; the electrode runs 30 to 140 kV through the paint at 0 to 225 microamperes. So, it is mean that the electrical force needed to guide paint particles to the work piece is 8,000 to 10,000 volts per inch of air.

The principle of Manual Liquid Electrostatic Spray Gun for Electrostatic Coating

In using the liquid electrostatic spray gun , the high compress air tends to throw the paint away when the paint passes through the special nozzle, the droplets pick up the charge from an electrically charged electrode at the tip of the gun by charged electrode. The charged particles are given their initial momentum from the fluid pressure/air pressure In this case, the expelling effect appears between the paint carrying electrostatic and the live particles as to cause further atomization of paint and thus, forming much finer thin fog. Due to the occlusion of electrostatic, the lost paints are sucked back to the workplace in generating a kind of surrounding electrostatic effect and the over spraying phenomenon is thus minimized. In this way, the machine has achieved the purpose of electrostatic coating.

Transfer Efficiency of different Spray Technologies

The principle of Turbo Rotary Atomizer (DISK) for Electrostatic Coating

Rotary atomization is a variation of electrostatic spraying that uses centrifugal force generated by discs to atomize paint, which drives it from the spray disk. In this case, the expelling effect appears between the paint carrying electrostatic and the live particles as to cause further atomization of paint and thus, forming much finer thin fog. Due to the occlusion of electrostatic, the lost paints are sucked back to the workplace in generating a kind of surrounding electrostatic effect and the over spraying phenomenon is thus minimized. In this way, the atomization of this method is excellent as is the transfer efficiency. This method also can be used with paints of different viscosity. Therefore the machine has achieved the purpose of electrostatic coating.
