Plasma cleaning equipment, how to remove solvents and additives from the surface, and gently and safely clean the surface, while plasma cleaning activation equipment provides subsequent adhesion of adhesives and coatings.
Atmospheric plasma cleaning technology helps to selectively process electronic components and can be fully integrated into standard online processes. This not only reduces processing time, but also lowers costs. Plasma cleaning provides efficient, precise, selective, permanent, and environmentally friendly surface activation,
Atmospheric plasma cleaning machine surface treatment equipment, plasma cleaner used for plastic metal surface treatment
Plasma is a state of existence of matter. Usually, matter exists in three states: solid, liquid, and gas, but in some special cases, there may also be a fourth state, such as matter in the ionosphere of the Earth's atmosphere. The following substances exist in a plasma state: high-speed moving electrons; Neutral atoms, molecules, and atomic groups (free radicals) in an activated state; Ionized atoms and molecules; Unreacted molecules, atoms, etc., but the substance remains electrically neutral as a whole. The atmospheric low-temperature plasma processor consists of a plasma generator, gas delivery system, pressure protection system, and plasma nozzle.
The plasma generator generates high voltage and high-frequency energy, which ionizes the air through activation and controlled glow discharge in the nozzle steel pipe, producing low-temperature plasma. The plasma is sprayed onto the surface of the workpiece with the assistance of compressed air. When surfaces come into contact, a series of chemical reactions and physical changes occur to clean the surface and remove hydrocarbon based pollutants.
The surface treated with atmospheric pressure plasma can be used to obtain a very thin high tension coating surface without the need for any other mechanical or chemical treatment to increase adhesion. Through low-temperature plasma surface treatment, various physical and chemical changes occur on the material surface, such as etching and roughening, or the formation of dense cross-linked layers, or the introduction of oxygen-containing polar groups to enhance hydrophilicity, adhesion, dyeing, biocompatibility, and electrical properties.
Under appropriate process conditions, the surface of the material is treated to significantly change its morphology. Multiple oxygen-containing functional groups are introduced to transform the surface from non-polar and difficult to adhere to to, to polar, easy to adhere, and hydrophilic, which is beneficial for bonding, coating, and printing.
Plasma gun is a handheld device that does not require an external gas connection. Simply plug in the power and start cleaning!! Very suitable for small production facilities, research laboratories, universities, or anyone who needs a small handheld plasma solution.
Plasma guns are very suitable for local cleaning and surface modification of large objects before bonding. This simple plasma device is a multifunctional and versatile solution that can be used directly without any settings. Like all of our systems, the plasma gun provides consistent and reproducible results.
According to the substrate being processed, the surface activation generated by the plasma rod usually lasts for about an hour, and the activation time of metals and silicon is longer than that of plastics and rubber.
Low temperature plasma guns include our standard nozzles, including direct injection plasma nozzles and rotary plasma spray guns, which are now widely used for cleaning plastics, rubber, and non-conductive materials. Depending on the product, choose the appropriate nozzle for treatment. Two optional cleaning nozzles are available for near-field nozzle cleaning of metals and conductive materials; Multi gas nozzle, allowing the use of gas or helium as input gas.
There are two types of nozzles for atmospheric plasma cleaning machines: one can directly perform plasma treatment on the conveyor belt. Suitable for online processing, without the need for any vacuum technology for plasma treatment of aluminum, it can generate a very thin oxide layer for local surface treatment (such as bonding grooves) and directly process objects on the conveyor belt. Based on the principle of plasma excitation, the processing traces of plasma are limited (approximately 8-12 millimeters). When dealing with large objects, multiple nozzles or various types of nozzles (such as direct spray+rotary spray combination) must be used, depending on the customer's needs and production capacity.
To some extent, plasma cleaning of easily oxidizable objects is limited, and complex multi joint robot technology is required for responsible 3D products. The permeability of room temperature plasma has certain limitations, and atmospheric pressure plasma cleaning machines are generally only suitable for planar processing. And the processed surface is single-sided, so if both surfaces need to be processed, the process flow will be quite complicated. The object must be accurately positioned on the conveyor belt, and the motion trajectory of the nozzle of the atmospheric pressure plasma cleaning machine with a motion platform can be set, but the object to be processed is required to be fixed on the motion platform.
