What is an electrostatic color?
Electrostatic paint should be considered an industrial paint that was first made in the 60s and 70s and used in America and England. Electrostatics are usually used in painting all types of metal surfaces due to better adhesion. One of the important issues about static color is related to its structure. These paints usually have a pre-heat, post-heat, spray torch and infrared structure. In addition, in different methods, its construction is different and finally the implementation process is also slightly different. Liquid and powder electrostatic paint are the most used types of this paint. Finally, many cars today are painted based on electrostatic paint structure.
☑️ Introduction to electrostatic staining methods
In general, there are four universal techniques for electrostatic paint spraying, which we will learn more about below. The first method is known as preheating. Of course, these color methods are used in the world. But we will also talk about them in terms of use in Iran. This article can be a good guide for companies that intend to develop dyeing technologies and fast processes for their products. In addition, these methods are usually used all over the world.
☑️ The pre -heat method of electrostatic paint
In this method, the first piece that we intend to paint. It receives heat and is then prepared for painting with a spray structure. After that, coloring in this way has certain characteristics, some of which include these items. In this method, the adhesion level of the electrostatic paint is extremely high, and the paint shows the best resistance against scratching, engraving, and separation from itself. In addition, scratches and resistance are created only if an electrical or chemical agent is involved. This method is used to paint small parts and usually the complexity of the parts that are painted is extremely high. If a company wants to guarantee the quality of its painting and wants electrostatic paint, pre-heat method is recommended.
☑️ The heat of the heat
The second technique we will examine. It is electrostatic. This method is the most common, the most popular and the most used technique in Iran, in which the whole piece is first painted and then exposed to heat. This way you have an easier overall structure for electrostatic paint bonding. The post-heat method can be applied both manually and mechanically. In addition, in both manual and automatic models, its speed is usually extremely high and there is no delay. Of course, its color is generally of good quality. But you have to remember that the electrostatic paint in the post-heat method can be of poor quality.
☑️ Infrared method
This method is done using a robot or a device called an electrostatic paint gun. Painting in this mode is done in such a way that first the robot does the painting, and then the painted piece or part is placed under the infrared lamp to obtain the necessary hardness. In addition, this method is suitable for parts that are usually larger than the baking ovens. Using the infrared method, any large object can be painted easily and in the shortest possible time. In addition, this method does not require extraordinary facilities and is one of the simplest electrostatic paint techniques. At the same time, in this method, painting is done at a slower speed, and if the parts are to be used in large numbers, they need to be painted first. Naturally, its cost is also high. It should be noted that this method is usually used by less industrial companies. except in sensitive and special cases.
☑️ Torch method
This method, as its name suggests, is in the category of electrostatic paint. It is done using a spray gun. At the same time, it sprays powder and flame towards the used material and is usually ideal for places that have a blind path and a limited path. In addition, diesel and gasoline compressors can be used. Even electrostatic paint can be transferred in this case in a desert without facilities. At this stage, there is no furnace and the paint spraying process usually does not have a good speed. If one layer and one part of the color is separated. Usually, other parts are also separated. It should be noted that in this method there is a need for specialized colors with a short cooking time. This method is usually the best and most ideal technique for pieces that are very large and bulky.
Electrostatic paint thickness
The thickness of electrostatic paint depends on various factors, which include the following:
The type of colors used is very important. So that the colors that have more zinc, create more thickness.
The distance between the electrostatic tool and the part is very significant. So that the shorter the distance, the greater the coverage and thickness of the static paint.
The higher the voltage, the thicker the electrostatic coating.
The higher the speed of applying paint on the surface of the desired piece, obviously, it reduces the thickness of the static paint.
In addition to the mentioned cases, the more unfavorable the environmental conditions are, the more it affects the thickness of the electrostatic paint. High temperature makes the thickness less and high humidity makes the coating thicker.
☑️ Electrostatic paint properties
Generally, electrostatic paint has a high resistance to changes in temperature, humidity, freezing and cold. It can also be used in any space. Of course, provided that it is well implemented. In addition, the electrostatic paint makes the material very beautiful and it can be easily sold as a stainless product. Likewise, color change is not achieved in a long time. Surface washing is possible. Uniform thickness is created throughout the section and excellent coverage can be achieved using it. Finally, inaccessible points can be easily painted using electrostatic paint. Electrostatic paint is anti-scratch and impact-resistant, and a wide range of colors can be used.
☑️ The benefits of electrostatic paint
This method has many advantages, which we will discuss below. The first thing is that no chemical compounds are used in it, and there is no heavy and toxic metals. Meanwhile, organic compounds and solvents There is no organic in it and it is extremely economical if used in large quantities. Its efficiency is considered to be close to 90%.It can be used for different thicknesses of metals. It has an extraordinary uniformity for covering the entire material. After the baking stage, it can be easily used using an electrostatic paint oven. Also, its use is extraordinary. It is easy and does not cause any damage to the respiratory system and human body system. Of course, compared to other coloring methods, electrostatic color can be done only by using a mask, and it can be applied in any area due to its causal movement and distribution. A route used by the contract. These colors are extremely resistant to scratches, frost, rain, etc.
☑️ Difference of powdered and liquid electrostatic paint
Generally, liquid electrostatic paint has an extremely high cost. Training and expertise are needed to implement this method. In addition, the deterioration and dripping of paint is one of the biggest problems that we do not face with electrostatic paint in powder form. In addition, powder colors are easy to use and do not need to be changed. Above, we discussed the benefits of electrostatic paint and read the necessary explanations in this case.
In general, powder colors are the ideal option. But in certain atmospheric conditions, they have less resistance than liquid electrostatic paint material. In addition, when electrostatic paint is used, it may show less resistance to a sharp object than liquid paint. Of course, in general, electrostatic powder paint is one of the best options available in the market and shows great resistance in every way. Therefore, static color is one of the most ideal options for small and large industrial companies that intend to implement various projects.
What is an electrostatic application?
These colors may be used less in construction. They are extremely widely used and ideal in the industry and can optimize the company's production line several times in terms of efficiency. The applications of electrostatic paint can be painting the car body, doors and chassis, coating machine parts and industrial tools, painting wooden parts of sofas, doors and windows, painting circuits and electronic parts, coating plastic parts, etc. Let's mention In general, electrostatic paint is used for painting in the automotive industry, household appliances, electronics industry, wood industry, light and lighting industry, etc.
