Questions and Answers

What are the advantages of Plasmatreat's atmospheric pressure plasma equipment, Openair-Plasma® technology, over other surface preparation processes?

The main advantage is the industry's highest plasma injection power, which allows us to clean and activate the object's surface simultaneously and quickly. Besides that, our plasma system is a dry process using an air compressor (air compressor), which not only reduces running costs but also eliminates the need to worry about ozone generation. Another advantage is that it can be easily integrated into existing production lines, is environmentally friendly, and saves space, since it does not require the large-scale ancillary equipment that is needed for vacuum plasma.

 

What is required to operate a plasma system?

Our plasma systems require an AC power supply (100V/230V/400V) and an air compressor. Depending on the work environment, we recommend the use of local exhaust ventilation. We can also install a voltage converter when required for use in Japan.

 

What is the production speed for surface treatment?

The processing speed is determined by the balance of the nozzle travel speed and the distance from the nozzle tip to the object in relation to the adhesive strength required for the material. For example, the maximum speed of PFW10 is 900 m/min, but for profile materials such as EPDM / TPE, the optimal speed is 2 to 30 m/min. However, the speed is affected by the shape and the ratio of the blended components. However, since the reaction varies depending on the shape and the ratio of the blended components, we will first propose the optimum parameters for your needs during a demonstration in our laboratory.

 

Can Openair-Plasma® technology replace conventional (chemical-based) methods?

Yes, it is possible. In fact, atmospheric plasma is not only highly effective for surface activation, surface cleaning, and other surface pretreatments, but it is also suitable for automation because it is a machine-operated process. Our plasma systems are widely used in a variety of fields, regardless of industry, and we offer the best solutions to our customers based on our accumulated know-how and experience.

 

Why is the Openair-Plasma® process so effective for bonding and joining composite materials?

The Openair-Plasma® process is a low-temperature plasma technique that provides the highest plasma density in the industry for pretreatment of composite materials. This allows for rapid processing and surface modification without adversely affecting the material to be processed.

 

Why are Plasmatreat's atmospheric pressure plasma systems so easy to integrate into production lines?

Our Openair-Plasma® systems have very compact nozzles that can be moved freely within the length of the cable. Another major difference is that plasma processing equipment using gases (other than air), such as vacuum chambers and corona discharge/flame treatment, which are required for vacuum plasma, does not require special ancillary equipment such as ozone exclusion equipment, as required by law. Therefore, the design can be prioritized to the customer's usage and existing production line, making it easy to integrate into the production line.

 

What are the running costs incurred?

The surface treatment process with Openair-Plasma® incurs running costs mainly in electricity and compressed air consumables (plasma head, filters, etc.), as well as costs due to equipment maintenance. Details on the voltage of the plasma generator and plasma generator can be found here.

Can Openair-Plasma® process thermally sensitive materials?

The plasma temperature near the injection hole is about 300°C, which is lower than that of most atmospheric plasma systems, The surface of the plasma-treated object is limited to a rise of about 15°C. Depending on the treatment method and material, the plasma temperature may rise by as much as 30°C. Depending on the processing method and material, the temperature may rise as high as 30°C. Plasma treatment is also used in the pre-processing of heat-sensitive DVDs and integrated circuits (ICs).

 

Does plasma treatment produce any harmful emissions?

Ozone emissions in our Openair-Plasma® process are extremely low compared to typical atmospheric pressure plasma systems. Instead, depending on the material, trace amounts of hazardous gases such as nitrogen oxides (NOx), carbon monoxide (CO), and other oxides may be produced by evaporation of materials that have adhered to the surface. This is why we promote the installation of local exhaust ventilation and automatically include inhalation devices in our set of processing stations.

 

Does Openair-Plasma® require special gases?

Openair-Plasma® can be used with any special gases, but without any special reason, it does not require anything other than electricity and oil-free compressed air. If you do not have your own air compressor or other equipment, we can deliver a plasma unit with our low-pressure side-channel compressor. Please feel free to contact us.
