Air plasma surface treatment machine to improve the quality of spraying printing or bonding:
In order to make products, including all kinds of plastic products, have better spray, printing or bonding quality, product surface treatment is required. Traditional surface treatment techniques include mechanical polishing, chemical solvents, flame, corona and other different treatment methods. These processes have their own technical advantages and characteristics, but they also have their limitations in technology and application.

CRF plasma surface treatment machine
Atmospheric pressure plasma treatment technology is a new technology for plasma surface treatment. Compared with the traditional treatment technology, the treatment effect, operation safety, treatment cost, application adaptability and environmental protection have been significantly improved.


So let's talk about what plasma is. Solid, liquid and gas are three common aggregation states of matter, the process of substance changing from solid to liquid and then to gas. If we continue to apply energy to the gas, the velocity of molecules in the gas will be further accelerated, forming a new aggregate state of matter, including ions, free electrons, excited state molecules and energetic molecular fragments, known as the fourth state of matter -- "plasma state".


Atmospheric plasma surface treatment machine is in the atmospheric pressure to produce plasma, product surface treatment. With the aid of the plasma spray gun, atmospheric plasma introduces air or other process gases into the spray gun, and at the same time introduces a high frequency and high voltage current to apply energy to the gas. The plasma needed comes out of a nozzle at the front of the gun, and the resulting plasma is electrically neutral, so it can be used not only to treat plastics, but also metals, glass and other materials.


The influence of plasma treatment on the material surface is mainly manifested in three aspects:
1. clean the surface, remove organic and inorganic pollutants.
2. Surface activation improves the surface energy of the material.
3. Eliminate static electricity.


Plasma cleaning surface can not only remove inorganic pollutants such as dust on the surface of materials, but also decompose organic pollutants such as oil on the surface. Surface activation of plastic materials can greatly improve the surface energy by forming new active functional groups on the surface of the materials. It can improve the inert surface below 30mN/m to 72mN/m hydrophilicity


Atmospheric pressure plasma treatment technology is widely used for surface treatment of plastic, metal or glass materials in various adhesive treatment, spraying treatment and printing treatment processes. The resulting clean, highly active surface makes it easier to bond, spray and print, thus improving processing quality, reducing processing costs and improving processing efficiency.
