Why use low-temperature plasma cleaning equipment? 

In many manufacturing fields, besides relying on third-party agents to remove surface residues, plasma cleaning equipment or plasma processors can meet this requirement. 


Plasma cleaning equipment can be used for a range of materials and surface treatments with complex geometric shapes. Over time, plasma cleaning equipment can effectively clean surfaces without negatively affecting other surface properties. The efficiency of low-temperature plasma cleaning technology has been recognized and used for pre-treatment cleaning of various materials.


Today, let's delve deeper into what plasma is? Firstly, it is a unique processing medium used for surface treatment and modification. Plasma is a plasma, and electric plasma is considered the fourth state of matter.


Ionizing gases are composed of atoms and neutral atoms.


Although the electron temperature in plasma is higher than that of neutral gas, plasma always approaches ambient temperature. Through chemical reactions (air plasma) or physical ablation (argon plasma/argon plasma), low-temperature plasma cleaning has the effect of effectively removing all organic pollutants on the surface.

The low-temperature plasma cleaning system can also treat chemical functional groups, such as carboxyl and hydroxyl groups on the surface. With the increase of wettability, the contact angle of water decreases to enhance the bonding or adhesion with other surfaces. After plasma cleaning treatment, the hydrophilicity of the surface can be improved.


Plasma cleaning equipment can also be used to remove surface microbial contaminants, which makes it extremely beneficial for the research and application of biomaterials.


What is the difference between low-temperature plasma cleaning and traditional cleaning methods?


Firstly, plasma cleaning machines are effective. Plasma cleaning equipment is more efficient in removing surface pollutants, including organic and microbial contaminants. It can thoroughly 

clean residues under the microscope to ensure thorough cleaning. Secondly, it is environmentally friendly: Unlike traditional chemical cleaning, plasma cleaning equipment is environmentally friendly as it eliminates the need for chemical solvents and reduces the impact on the environment and solvent storage and handling.


In addition, cost-effectiveness: Plasma cleaning equipment has lower operating costs and negligible maintenance costs, making it a traditional option. The plasma processing machine will not have a negative impact on the performance of the cleaned surface. Unlike some traditional methods, these methods may be very strict and destructive. In addition, plasma cleaning systems are easy to operate and use, making them a convenient choice for various industries.


Plasma cleaning equipment is widely used in the automotive industry, such as cylinder heads, valves, pistons, crankshafts, and other accessories inside car engines. During the production and processing process, impurities such as oil stains, carbon deposits, and metal shavings can be contaminated. Plasma cleaning machines can decompose and remove impurities through 


physical and chemical reactions with high-energy ion beams, ensuring that the surface of the parts reaches a high level of cleanliness and improving the performance and lifespan of the engine. The low-temperature plasma cleaning machine can effectively remove these pollutants, improve the cooling and heating effects of the air conditioning system, improve the air quality inside the car, and provide a healthier and more comfortable environment for drivers and passengers.


In the welding process of automotive parts, such as the welding of engine cylinder blocks and frames, the surface quality of the welding parts directly affects the welding quality and connection strength. The linear plasma cleaning machine can remove oxides, oil stains, and other impurities in the welding area, making the welding surface cleaner, increasing surface energy, allowing the solder to better bond with the surface of the part, reducing problems such as virtual welding and desoldering, and improving the quality and reliability of the welding joint.


For car body, bumper, wheel hub and other accessories, using a plasma cleaning machine before painting can activate the surface, making it change from non-polar and difficult to stick to a certain polarity, easy to stick and hydrophilic, which helps to evenly adhere the coating, enhance the adhesion between the coating and the accessory surface, prevent coating peeling and flaking, improve the beauty and durability of the coating, and enhance the appearance quality and adhesion of car parts.


In summary, plasma cleaning machines only require the use of process gases such as air, oxygen, and argon for treatment at room temperature. They are environmentally friendly, do not use chemical solvents, and do not cause pollution to products and the environment, meeting the environmental requirements of many modern manufacturing industries.
