Atmospheric Pressure Plasma System

Atmospheric Pressure Plasma System – Advanced Surface Treatment Solution

Overview

The Atmospheric Pressure Plasma (APP) System is a cutting-edge surface modification technology designed for high-efficiency, eco-friendly cleaning, activation, and functionalization of materials in various industrial applications. Unlike traditional vacuum plasma systems, this equipment operates at ambient pressure, eliminating the need for complex vacuum chambers and significantly reducing operational costs while maintaining excellent process consistency.

Ideal for use in electronics manufacturing, automotive, medical devices, packaging, and renewable energy sectors, our APP system leverages dielectric barrier discharge (DBD) o plasma jet technology to generate a stable, non-thermal plasma field that enhances surface wettability, adhesion, printability, and biocompatibility without damaging delicate substrates.

How It Works: Principle of Plasma Generation

Plasma is often referred to as the “fourth state of matter,” formed when gas molecules are ionized by high-energy electrons. In atmospheric pressure plasma systems:

A high-frequency AC or RF power source (typically 10–100 kHz) is applied across electrodes.
Ambient air or inert gases (e.g., Ar, N₂, O₂) are introduced into the treatment zone.
Under electric field acceleration, electrons collide with gas molecules, generating reactive species such as ions, free radicals, UV photons, and excited atoms.
These reactive species interact with the surface of materials, breaking down organic contaminants, oxidizing hydrophobic layers, and creating active functional groups (e.g., –OH, –COOH), thereby improving surface energy and adhesion properties.

This process occurs without heating the substrate, making it ideal for temperature-sensitive materials like polymers, films, and flexible electronics.
