Plasma air rod

Plasma wind rods ionize process gases into plasma by applying an electric field. The "active" components of plasma include ions, electrons, atoms, free active groups, excited state nuclides (metastable states), photons, etc. Plasma treatment is the process of utilizing the properties of these active components for physical and chemical reactions such as oxidation, reduction, cracking, cross-linking, and polymerization to alter the surface properties of samples, thereby optimizing material surface properties and achieving cleaning, modification, etching, and other purposes.

The SPA-2600 plasma cleaner is a product that performs surface cleaning, activation, and etching in a normal pressure environment. It is usually paired with a jet straight spray gun head, and is mainly used to handle materials with small areas, high processing trajectory accuracy, and many corners. It is the "nemesis" for problems such as poor adhesion, welding, printing, and easy glue detachment in various industries. Plasma cleaning, as a pre process for surface printing, packaging, bonding, coating, welding, adhesive bonding, and coating of products, is an important link for enterprise product upgrading, capacity expansion, and cost reduction.

Under the excitation of high-voltage power supply, process gases such as compressed air and oxygen are ionized in the atmospheric environment to generate plasma, which directly acts on the surface of the product for cleaning. By using atmospheric plasma treatment, the surface activity of the material is improved and the surface adhesion is enhanced.

　　2、 The structure of plasma wind rod is mainly divided into three components, namely high-voltage excitation power supply, plasma generation device spray gun, and control system

1. High voltage excitation power supply: The generation of plasma requires high voltage excitation, and atmospheric plasma is excited by an intermediate frequency power supply with a frequency of 10-4OKHz. The high voltage is between 4-10KW. The parameters can be adjusted according to the actual situation of the sample to achieve the desired modification effect.

2. Plasma generating device spray gun: Atmospheric plasma generating device spray gun. According to the size of the processing area, plasma spray guns can be divided into two types: jet direct spraying and rotary spraying.

(1) Jet straight spray nozzle:

Optional nozzle: ① Ordinary jet direct spraying ② Flat nozzle jet direct spraying

Optional specifications for ordinary jet direct injection: 2m, 3mm, 5m, 10mm

Flat nozzle jet direct injection optional specifications: 10mm, 15m

(2) Rotating nozzle:

Ordinary nozzle: 20mm, 30mm, 50mm, 70mm

Silencing nozzle: 20mm, 30mm, 50mm, 70m

3. Control system: The function of the control system is to control the operation of the entire atmospheric low-temperature plasma cleaning equipment and protect the overall system.
