Electrostatic Powder Coating

Electrostatic Powder Coating

Electrostatic Powder Paint application is an application that is frequently applied in the manufacturing industry and has a higher durability than wet paint application. These powders, which are electrostatically applied to the target of dry and free flowing powders, form a layer on the material. Then the material is sent to the paint oven and this layer is hardened and forms a shell. This shell is highly resistant to outdoor conditions. Electrostatic powder coating can also be applied to non-metal substrates such as plastic and chipboard.

1. DUST AND FUME RELEASED DURING ELECTROSTATIC POWDER PAINT

In the powder coating process, after the paint adheres to the material, some particles remain in the air. These particles are generally large in volume. These particles, which are released after electrostatic powder paint, must be removed from the environment with an efficient dust collection system. These particles are very harmful to human health. Depending on the chemical used, it may cause respiratory, skin and eye problems. In order to minimize these risks that occur during electrostatic powder paint application, a properly working dust collection system is required. These particles formed during electrostatic powder paint application are of medium to light density, and their particle sizes vary between fine particles and fumes. Some particles may retain water or clump when exposed to moisture.

Dust and smoke released during electrostatic powder paint application are generally corrosive and may have a risk of fire and explosion depending on the material. It may also have water retention or clumping properties depending on the material and the paint chemical used. Bomaksan engineers make specific product selections for your electrostatic powder coating application. EX-PROOF filter units can be manufactured with ATEX certified equipment for applications with explosion risk, and customer-specific studies can be carried out on the measures to be taken against all kinds of fire and explosion risks.

In order to create an efficient and healthy working environment, it is necessary to remove and filter the smoke and dust caused by all these applications from the breathing air of the employees in a healthy and effective way. Factories that do not increase precautions for work accidents and occupational diseases, thanks to the increased awareness and awareness in recent years, both experience a shortage of qualified personnel and face lawsuits with serious consequences in the long term. Firms that take precautions against work accidents and occupational diseases at the highest level have increased productivity thanks to employee satisfaction as well as providing a sustainable production center.

2. WHAT SHOULD BE CONSIDERED WHEN DESIGNING THE SUCTION SYSTEM?

The main points to be considered when designing a ventilation system for the suction of dust and smoke released during electrostatic powder paint application are as follows;

  • Corrosive dust resistant steel channels

Spiral clamped galvanized piping is not suitable for this application because the dust released during electrostatic powder painting is abrasive. Systems made with spiral clamped pipes are starting to cause problems in a short time.

  • Precautions Against Fire Risk

Electrostatic powder paint powder and smoke have a risk of fire, depending on the type of material that is electrostatic powder painted. In cases where this risk occurs, measures should be taken to ensure that the spark can reach the filter, and measures should be taken to minimize the damage in case of a possible fire.

In cases where this risk occurs, measures should be taken to ensure that the spark can reach the filter, and measures should be taken to minimize the damage in case of a possible fire.

  • Precautions Against Explosion Risk

Electrostatic powder paint powder and smoke have the risk of explosion, depending on the type of material that is electrostatic powder painted. In cases where this risk occurs, precautions for sparking to the filter as well as measures to minimize the damage in the event of a possible explosion should be taken.

  • Design for Reducing Electricity Consumption

There can be different electrostatic powder paint applications in each industry. While some companies paint small parts, some companies can paint much larger parts. However, regardless of the application, the system designer must take the dust and smoke extraction from the closest possible point in order to reduce the electricity consumption and the initial investment cost. In addition to being close to the suction point, the fact that the suction area is closed as much as possible will reduce the size of the device in the initial investment and minimize electricity consumption. Bomaksan Engineers will assist you in such system designs.

Use it to determine the filter efficiency and capacity of particles in the range. Minimum MERV 15 filters should be used for the filtration of dust and smoke released during the grinding process.

Filter media (the area where dust and fumes are kept in the dust extraction unit) plays a critical role in the efficient filtering of fumes released during electrostatic powder coating application. In processes where the filter media cannot be selected correctly, undesirable consequences such as frequent clogging of the filters, high electricity consumption, frequent interruptions of the electrostatic powder coating process may occur. Therefore, high quality filter media must be used.

In addition to the filter media, a good Jet-Pulse dust collector should have a highly efficient cleaning system, easy maintenance and universal spare parts. Bomaksan brand filter units are superior to other brands thanks to these superior features.

 

3. CHOOSING THE RIGHT FILTER UNIT

Dust collection systems used for the suction and filtration of dust and fumes during electrostatic powder coating application are very critical for the effective collection and filtration of submicron particles (less than 1 µm). ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) uses the Minimum Efficiency Rating Value (MERV) criterion to determine the filter efficiency and capacity of particles within a certain size range. Minimum MERV 15 filters should be used for the filtration of dust and smoke released during the grinding process. DUST COLLECTOR RENDER
