The cleaning method without secondary pollution by plasma treatment machine before printing and spraying. The plasma cleaning machine has the following characteristics after plastic surface treatment: excellent surface cleaning effect, removal of organic pollutants, activation of surface chemical bonds, expansion of material applicability, and improvement of compatibility between different materials,

Before printing or spraying, organic pollutants may remain on the surface of processed materials such as plastics, metals, etc., such as oil stains, grease, release agents, etc. The active particles (such as oxygen radicals) in the plasma undergo chemical reactions with these organic pollutants, decomposing into small molecules such as carbon dioxide and water, which are then pumped out of the reaction chamber through a vacuum pump. This cleaning method can deeply remove organic pollutants, reduce surface organic residues to extremely low levels, and ensure the purity of the printed or sprayed substrate surface. As is well known, plasma processing machines can increase the number of active groups in the pre-treatment of printing and spraying.

In real life, there are many methods to increase active groups, and the following are some commonly used methods:

1. Surface treatment agent: Coating the surface of the equipment with a special surface treatment agent can form a protective film of more active groups on the surface, in order to improve the reactivity and adsorption capacity of the equipment surface.

2. Ion implantation: Using ion implantation technology, ions with active functional groups are injected into the surface of the device, gradually increasing the surface active functional groups.

3. Plasma treatment: Using plasma treatment technology, surface molecules are activated by plasma to have more active groups, improving surface reactivity and adsorption capacity Chemical spraying: Using a special spraying process, a chemical substance with active functional groups is uniformly sprayed on the surface of the equipment, causing it to adhere to the surface and form a coating with more active functional groups. Through the application of the above methods, we can effectively increase the active groups on the surface of the equipment, improve its reaction components and absorption capacity, and achieve better results before cleaning the printing and spraying plasma generator. The following is an analysis of the application characteristics of plasma treatment machines on the surface of rubber and other materials:

1. The physical impact of the plasma cleaning machine can cause these particles to detach from the surface. Meanwhile, plasma can also form charges on the surface of materials, making it easier for dust and other particles to be attracted and removed by static electricity, thereby significantly improving the cleanliness of the material surface. Plasma cleaning technology can remove inorganic particles, remove surface impurities such as dust and metal particles on the material surface, and also affect printing or spraying quality.

2.The interaction between low-temperature plasma and material surface can break the chemical bonds on the material surface, forming new active groups such as hydroxyl and carboxyl groups. These active groups can enhance the chemical reactivity of the material surface, allowing printing inks or spray coatings to better react with the material surface, thereby enhancing adhesion. Plasma cleaning machines can enhance surface activity and wettability.

3. Through low-temperature plasma treatment, the chemical composition and structure of the material surface can be adjusted, thereby changing its surface energy and humidity. For example, for some originally hydrophobic materials such as plastic films, plasma cleaning can make their surfaces hydrophilic, making it easier for printing ink or spray coatings to spread and adhere on the surface, avoiding ink or coating aggregation and shrinkage, and improving the uniformity of printing or spraying.

4. The active groups generated by low-temperature plasma cleaning can undergo chemical reactions with the chemical components in ink or paint, forming chemical bonds. This chemical binding force is much stronger than simple physical adsorption, which can effectively prevent printed patterns or spray coatings from falling off and fading during use, improving product quality and durability. Plasma cleaning machine can quickly improve the adhesion of printing or spraying;

5. Plasma cleaning improves the wettability of the material surface and the adhesion of ink or paint. Therefore, during the printing process, ink can be more accurately transferred to the material surface, making the edges of the pattern clearer and the lines more delicate. This effect is particularly important in high-precision printing fields such as electronic circuit board printing and label printing. Plasma cleaning technology can improve the accuracy and quality of printing or spraying.

6. For the spraying process, the surface of the material treated by the plasma cleaning machine can evenly distribute the coating, avoiding problems such as uneven thickness and hanging. This can significantly improve the appearance quality and performance of the product, suitable for applications such as automotive coatings, furniture coatings, etc. that require high-quality coatings.

7. Plasma cleaning can process various materials, including paper, plastic, metal, glass, ceramics, etc. This enables plasma cleaning to improve surface performance and expand the applicability of printing and spraying techniques when printing or spraying different materials. For example, in some new composite materials, plasma cleaning can be used for smooth printing or spraying to meet diverse product design and production needs.
