What is electrostatic spraying? What is the working principle of electrostatic spraying equipment?
Electrostatic spraying refers to the use of corona discharge principle of atomized paint in the high-voltage DC electric field under the action of negatively charged, and adsorbed in the charge of positively charged substrate surface discharge coating method. Electrostatic spraying equipment from the gun, spray cups and electrostatic spraying high-voltage power supply and other components.
The working principle of electrostatic spraying equipment: in the electrostatic spray gun gun, connected to a negative high voltage electrostatic, when the voltage reaches a high enough, the gun near the region of the air to produce a strong corona discharge, the formation of gas ionization region. When the electrostatic spray gun atomized paint particles in the region, the atomized particles of paint will be negatively charged. The painted workpiece is suspended on a grounded conveyor line, and there is a positive charge on the surface of the workpiece. According to the principle of static electricity, the negatively charged paint atomized particles will move to the work surface of heterogeneity, be adsorbed and deposited on the surface of the workpiece to form a layer of uniform and dense paint film, and the workpiece will be coated.
The difference between friction electrostatic spraying equipment and high-pressure electrostatic spraying equipment
The following engineers from the Strong Mechanical automatic spraying equipment manufacturer will answer your questions:
1, friction electrostatic spraying equipment
The friction electrostatic spraying doesn't need the high-voltage static generator that is used in high-voltage electrostatic spraying, and it doesn't need to set up a high-voltage static plant between the powder spray gun and the workpiece. The key lies in its powder spray gun made of strong electronegative materials, when the two electronegative different materials project friction, weakly electronegative materials will be positively charged, while the strong electronegative materials will be negatively charged. When using weakly electronegative film-forming materials for powder coating, the collision between powder coating particles and the friction between the powder and the gun body made of strongly electronegative materials will make the powder particles take on a positive charge. So in the selection of suitable materials to make the spray gun, the powder in the compressed air to promote the movement in the gun body to produce friction and with a positive charge, in the air flow under the continuous promotion, will fly to the grounded workpiece and be adsorbed on it, this layer of loose coating film after curing will form a uniform continuous and smooth coating film.
2, high-voltage powder electrostatic spraying equipment
In the high-voltage electrostatic spraying powder, and solvent coatings are the same, in the electrostatic spray gun and workpiece between the application of high-voltage electrostatic, the gun and the negative electrostatic field connected to the workpiece connected to the ground. The difference is that the powder coating is in the purification of compressed air under the action of the powder supply through the powder tube into the powder electrostatic spray gun. In the gun head is equipped with a sharp edge of the metal ring or pole needle as the electrode. When the electrodes are connected to high voltage electrostatics, a corona discharge is generated and a dense negative charge is produced in the vicinity of the electrodes. When the powder coating is sprayed from the head of the electrostatic spray gun, it will capture the charge and become negatively charged, and fly to the workpiece and adsorb on its surface under the action of airflow and electric field.

How much does a set of electrostatic spraying equipment cost?
The price of electrostatic spraying equipment is generally in the tens of thousands of dollars to hundreds of thousands of dollars, spraying equipment belongs to the non-standard equipment, this product is not very clear, the specific circumstances of the equipment should be based on the construction of the program to determine the spraying equipment belongs to the non-standard equipment generally need to be tailored to the specific price of the manufacturer to contact.
What is electrostatic spraying?
Atomized paint particles in the DC high-voltage electric field with a negative charge, under the action of the electric field force, the paint particles fly to the positively charged surface of the workpiece, the formation of a film of paint, a process known as electrostatic spraying.
Principle:
Electrostatic paint spraying is to be coated as a positive electrode, the daily situation of grounding; paint atomization device for the negative electrode, connected to the power supply negative high-voltage, so that in the two poles into a high-voltage static field. As the cathode breeding corona discharge, can make the spray paint medium charged, and further atomization. In accordance with the principle of "homogeneous repulsion, heterogeneous attraction", has been charged paint media by the action of the electric field force, the paint on the coated object to form a ring effect, along the power line directed flow to the positively charged coated object appearance, stacked into a layer of average, firmly attached to the film. Electrostatic painting technology can also be used positive corona discharge, but the critical voltage of negative corona discharge is lower than positive corona discharge, and more stable, less likely to produce sparks. In the usual scenario will be coated as a positive grounding.

Composition and structure of powder electrostatic spraying equipment
Powder electrostatic spraying equipment mainly includes: powder spraying room, high-voltage electrostatic generator, electrostatic spraying gun, powder supply, powder recycling device, the workpiece rotating mechanism, etc. 1, Classification: the gun can be divided into handheld powder spraying gun, fixed automatic powder spraying gun, disc spraying gun and so on according to its use; according to the form of charged into internal charged gun. Charged form is divided into internal charged gun and external charged gun; according to the form of its diffusion mechanism can be divided into conflict type gun, rebound type gun, the second into the air gun, centrifugal spinning cup type gun.
2, spraying efficiency: powder spraying gun charged mechanism is to improve the form of spraying efficiency is a very key factor. Generally speaking, the core of the powder spraying equipment is the gun and charging system. As far as the market is concerned, the corona type spray gun accounts for a great proportion, this is because the use of high-voltage corona discharge way of charging the powder has the biggest advantage is that it can spray all kinds of thermosetting powder coatings today, and can get very good results. The advantages are mainly manifested in excellent stability, powder loading rate and powder loading speed.
3, the development of the gun is this: voltage control o current control o total energy control. Total energy control is with the gun distance from the workpiece components, its voltage, current are constantly adjusted to the ideal state, in order to achieve the best coating effect.1) Powder supply system is the powder coating material, from the powder container continuous and uniform transportation to the powder spray gun for spraying.
The powder supply system consists of air compressor, oil-water separator, air dryer, regulating valve, compressed air pipeline, solenoid control valve, powder feeder, powder pipeline and so on.
2) the form of powder supply
In the powder electrostatic spraying powder supply system, the use of more types of powder supply, usually can be divided into: pressure vessel type, screw or turntable mechanical conveyor type, venturi air suction type.
3) powder recovery device
Powder recovery can be divided into wet and dry method.
Wet method is to let the air flow with powder through the liquid container for filtration, to achieve purification, with liquid powder after drying and reuse.
The dry method of powder recovery is to collect the powder particles in the powder gas stream discharged from the powder spraying room. Dry method of powder recovery types are gravity settling type, inertia separation type, cyclone separation type, sintered plate separation type, etc., in the actual production, often using multi-stage recycling device, in order to achieve a better separation effect.
