Plasma cleaning machine and flame treatment machine are two common surface treatment equipment, mainly used to improve the adhesion, wettability, and cleanliness of material surfaces. Their working principles, scope of application, and advantages and disadvantages are different. Here is a detailed comparison?

What are the differences in the working principles between plasma cleaning machines and flame processing machines

1. Both plasma and flame surface treatment machines can clean, etch, and functionalize surfaces, and they can be combined with inks, adhesives, coatings, and coatings on plastics, composite materials, glass, and metals. But how are they similar and how are they different?

Atmospheric plasma treatment is a unique surface treatment technique for electronic assembly, nano cleaning, removal of organic pollutants, surface activation/modification, surface etching, hydrophobicity, passivation, hydrophobicity, and biocompatibility of almost all materials (composite materials, plastics, metals, glass, cardboard, textiles, etc.). Plasma is formed by blowing atmospheric air to a high-voltage power supply electrode, sometimes referred to as electrical treatment, where electrical discharge positively charges surrounding ion particles. By direct contact, these particles positively charge the surface treatment area of the object, and inert gases can be introduced into the plasma process to generate variable chemical plasmas.

2. Flame plasma is formed when combustible gases and atmospheric air combine and burn to form a strong blue flame. The surface of an object is polarized because the species in the flame plasma affect the distribution and density of surface electrons. This polarization is achieved through oxidation. Flame plasma is highly effective in high-speed processing of small or large areas, and can generate higher processing levels than air plasma. Due to the fact that they generate more heat than air plasma, they may not be suitable for every application.

What is the difference in the scope of application between plasma cleaning machines and flame processing machines

1. Plasma treatment can not only remove organic residues on the surface of materials, but also bring new chemical functions and significantly improve adhesives. The wettability and surface properties of ink and paint surfaces are also low, and there are many types of materials suitable for efficient plasma cleaning machines: metal, glass, paper, cardboard, especially polymers (polypropylene, polycarbonate, polyethylene, PVC), composite materials, etc

2. Flame treatment machine: mainly used for plastics and rubber, such as packaging materials, automotive parts, plastic films, etc. Suitable for mass production, such as surface treatment before printing, painting, and bonding.

What are the advantages and disadvantages of plasma cleaning machine and flame treatment machine respectively:

Some important advantages and applications of plasma surface cleaning machines are as follows:

1. Plasma processors can clean and decontaminate surfaces;

2. The surface of silicone rubber and other products needs to be bonded and printed, and plasma cleaning and activation treatment are required before processing to enhance adhesion.

Before gluing injection molded parts, plasma activation treatment can be carried out;

Plasma treatment can remove pollutants while providing surface modification to promote adhesion of various coating materials. In addition, plasma surface treatment can promote the flow of thin film coatings without the need for other mechanical or chemical treatments.

Disadvantages of plasma processing machines: high equipment cost, slow processing speed, suitable for small batch or high-precision requirements.

Advantages of flame processing machine: fast processing speed, suitable for large-scale production, and low equipment cost.

Disadvantages: High temperature may damage the surface of the material, poor uniformity, unsuitable for complex shapes, poor environmental friendliness, and combustion may produce exhaust gas.
