For material surface treatment, traditional chemical methods can leave toxic substances, causing pollution to the material surface and affecting the health of users. In addition, surface treatment methods include gas thermal oxidation, flame treatment, corona treatment, mechanochemical treatment, low-temperature plasma treatment, etc. Compared with other dry processes, plasma technology has simple production equipment, easy operation, and almost no toxic or harmful substances remain on the surface of the treated material. The energy utilization efficiency is high, and the treatment effect is easier to control, making the forming of the material to be processed more accurate and suitable for large-scale continuous industrial applications. Therefore, using low-temperature plasma for material surface modification has gradually become one of the hotspots in the fields of plasma and materials science research.

Dielectric barrier discharge (DBD) is a method of generating low-temperature plasma at atmospheric pressure using a wide range plasma cleaning machine, which has shown broad application prospects in material surface modification due to its convenience, effectiveness, and low operating cost. The wide width plasma cleaning machine can obtain large-area low-temperature plasma at atmospheric pressure, and the device is simple and can be used online. It is particularly suitable for surface activation modification of large-sized plates and films. The following are its common application areas:

Application fields of DBD wide plasma cleaning machine

High molecular polymer

Polymer materials such as polytetrafluoroethylene (PTFE) and polyethylene (PE) are widely used in various fields of the national economy, but most polymer materials have low surface energy, poor surface adhesion, hydrophilicity, and electrical properties, greatly limiting their application range. The application of DBD wide plasma cleaning machine for surface modification of polymers can effectively improve their surface properties and expand their application range.

Fiber material

Many characteristics of textile fibers, such as wetting, dyeing, friction, anti shrinkage, anti fouling, adhesion, anti-static, etc., are related to their surface properties. The DBD wide plasma cleaning machine can achieve various effects on the surface modification of textile fiber materials, such as hydrophilic or hydrophobic finishing, which can improve the dyeing, anti-static, comfort, waterproof, and anti fouling functions of the materials; Changing the adhesion can enhance the strength of the material; Changing friction can improve spinnability, yarn strength, or fabric mechanical properties; Improving dyeing and color rendering performance can enhance the visual effect of fabrics.

Other materials

With the development of DBD application technology, the application scope of DBD in material surface modification is constantly expanding. In addition to polymer and fiber materials, researchers have also made some attempts to treat other types of materials with DBD plasma in recent years, and have achieved good results.

Wood is a natural material and a special polymer material. Using DBD plasma cleaning machine to improve the surface properties of wood can increase its comprehensive utilization rate and expand its application range. Researchers have conducted exploratory research in this area.

The DBD plasma cleaning machine can also be used for surface modification of inorganic metals and non-metallic materials (such as copper, aluminum, glass, etc.). After plasma treatment, the dirt on the surface of inorganic materials can be removed, making the surface clean and activated, increasing surface energy, and making the surface rough, improving surface adhesion and bonding strength.
