Rubber and plastic materials such as dry polypropylene and polytetrafluoroethylene do not have polarity, and some rubber and plastic components are difficult to bond when connected to the surface. Without surface treatment, the printing, bonding, and coating effects of these materials are very poor, and even impossible to carry out. If plastic products are treated with a plasma treatment machine for the surface, under high-speed and high-energy plasma bombardment, an active layer can be formed on the surface of the product, further enhancing the printing, bonding, and coating of rubber and plastic.

As is well known, plasma is usually defined as the fourth state of matter, although everyone knows the first three states of matter: solid, liquid, and gas, plasma is often unclear.

Plasma cleaning machine is considered an environmentally safe process because it does not release any harmful chemicals in large quantities in the environment. It can easily remove organic matter because the plasma cleaning process can decompose the surface pollutants that need to be removed. How does plasma cleaning work? Under normal circumstances, there are three types of plasma cleaning processes, and what are the differences between the argon oxygen plasma cleaning technology of Zhenyi Corporation? The specific details are as follows:

1. Oxygen plasma cleaning: The oxygen plasma cleaning process involves generating plasma from pure oxygen gas. The characteristic of oxygen plasma is that it has a high degree of oxidation, which means that when the plasma is similar to the chemical reactions involved in combustion, it is easy to decompose organic pollutants.

Due to the high oxidizing nature of oxygen plasma, it should not be used when the object to be cleaned is made of sensitive materials such as copper or silver, or generally when the object should not have an oxide layer after the plasma cleaning process.  

2. Hydrogen plasma cleaning: The process of hydrogen plasma cleaning involves generating plasma from pure hydrogen gas. The characteristic of hydrogen plasma is its high reducibility, which is opposite to the effect of oxygen plasma.

Although hydrogen plasma can create a reducing environment, it can still be used to remove organic pollutants.

One important application of hydrogen plasma is the removal of oxides. Due to the promotion of reduction reactions by hydrogen plasma, it is possible to reverse the oxidation reactions that lead to the presence of surface oxides. In oxidized metals, this means that after hydrogen plasma treatment, the metal will return to its pure state, exposing its surface directly to the environment.

3. Argon plasma cleaning is slightly different from oxygen or hydrogen plasma because argon plasma does not undergo chemical reactions with organic pollutants, but only exchanges energy through inelastic collisions.

Compared to carbon, oxygen, or nitrogen (components of organic pollutants), argon is a heavy element. The argon cations present in argon plasma can be accelerated and targeted towards organic pollutants, decomposing them into smaller molecules. These molecules, like other processes, will evaporate and be removed by the process gas flow.

One of the main benefits of plasma cleaning machines is their ability to thoroughly clean complex geometries and fine materials, making them crucial in fields such as semiconductor manufacturing, aerospace, automotive, and medical devices.  

1. For example, in the automotive industry, plasma cleaning technology has a wide range of applications, covering various automotive components from engine parts to interior and exterior, enhancing the adhesion of paint surfaces, ensuring the service life of coatings, and improving the overall quality of surface treatment. Plasma technology can significantly improve surface cleanliness and adhesion, which is crucial for critical components that require high reliability and durability. In addition, the plasma cleaning process is highly efficient and can be easily integrated into automated production lines, increasing output and reducing operating costs.

2. Plasma cleaning ensures high cleanliness required for key processes such as wire bonding, welding, and conformal coating applications, thereby improving the performance and lifespan of electronic devices. This can be precisely controlled and integrated into existing production lines, providing scalable and efficient solutions that can keep up with the rapid development and miniaturization trend of the electronics industry.

3. Plasma cleaning machine technology has become the cornerstone of manufacturing, renowned for its efficiency in cleaning, activating, and etching surfaces at the microscopic level. Plasma processes ensure surface treatment of various materials, including metals, plastics, ceramics, and glass. Surface cleanliness is crucial for manufacturing steps such as bonding, painting, and coating, directly affecting the quality and durability of the final product.

4. Plasma cleaning is a key process in semiconductor manufacturing, used for surface treatment and pollutant removal at the microscopic level.  

Plasma cleaning of optical lens surfaces can effectively remove organic residues, oxides, and other impurities, which is crucial for the reliability and functionality of semiconductor devices. Its compatibility with automated production lines improves the efficiency and yield of semiconductor production.

In summary, the application of plasma cleaning machines has the advantages of simple operation, no harmful substances before and after treatment, good treatment effect, high efficiency, and low operating costs.
