Low-temperature plasma surface treatment technology causes changes in the molecular structure of the material surface

Low-temperature plasma surface treatment technology causes changes in the molecular structure of the material surface

Low-temperature plasma surface treatment technology causes changes in the molecular structure of the material surface: Low-temperature plasma surface treatment technology refers to the use of high-energy particles in the plasma to bombard the surface of the material to degrade the surface material and increase the surface roughness. Add other active particles, such as oxygen plasma, to the plasma. A method of surface activation by reaction of surface substances. Plasma treatment technology can be used for the surface treatment of fibers, plastics, rubber and composite materials. Low-temperature plasma surface treatment technology provides a method for micro-modification of environmentally friendly and low-cost materials, and the modification process does not require mechanical processing and chemical reagents. Through the low-voltage plasma surface treatment technology, the surface of the material can be cleaned, activated, and etched, and the surface of plastic, metal or ceramic materials can be modified to improve its bonding ability or give new surface properties. Its potential medical value includes improving the hydrophilicity or hydrophobicity of the material surface, reducing surface friction, and improving the barrier properties of the material surface. Low-temperature plasma surface treatment technology is a technology that only changes a few atomic layers on the surface of a polymer to improve its surface adsorption capacity. The modified polyolefin, silica gel and fluoropolymer materials have good bonding properties. According to this similar principle, using plasma surface treatment technology, while obtaining the surface of the material that needs to be transplanted and polymerized, the physical properties of the material itself will not be lost. Plasma surface treatment has no effect on the physical properties of the material, and the position of the material after plasma treatment is generally indistinguishable visually and physically compared with the position not treated by plasma technology. Low-temperature plasma surface treatment is usually a plasma reaction that causes changes in the molecular structure of the surface or the arrangement of atoms on the surface. Plasma treatment can generate highly reactive groups in a low temperature environment, even in an inactive environment such as oxygen or nitrogen. In this process, the plasma also generates high-energy ultraviolet light, which together with rapidly generated ions and electrons provide the energy required to interrupt polymer bonding and produce surface chemical reactions. In this kind of chemical process, only a few atomic layers on the surface of the material participate, and the bulk properties of the polymer are likely to remain deformed. Choosing appropriate reaction gases and process parameters can promote certain specific reactions, thereby forming special polymer attachments and structures. Reactants are often used to make the plasma react with the substrate to generate volatile attachments. The appendages on the surface of the processed material are removed by the vacuum pump due to desorption, and the surface can be etched without further cleaning or neutralization.

Surface modification of materials by vacuum plasma cleaner can be divided into chemical and physical

Surface modification of materials by vacuum plasma cleaner can be divided into chemical and physical: As a new type of material surface modification method, vacuum plasma cleaner technology has attracted wide attention for its advantages of low energy consumption, low pollution, short processing time, and remarkable effects. What are the surface modification methods of vacuum plasma cleaner materials? It is generally believed that the surface modification of materials by plasma can be divided into chemical modification and physical modification. Chemical method refers to the use of chemical reagents to treat the surface of a material to improve its surface properties, including pickling, alkaline cleaning, peroxide or ozone treatment, etc. Physicochemical treatment refers to the method of treating the surface of a material through physical technology to improve its surface properties, including plasma surface treatment, light radiation treatment, flame treatment, mechanochemical treatment, film treatment, and surface modifier addition. Among the many modification methods, the low-temperature vacuum plasma cleaning machine is a method that has developed rapidly in recent years. Compared with other methods, the plasma cleaning machine has many advantages: First, cleaning is a drying process and does not require wet chemistry. The drying process in the treatment process, waste water treatment and other processes; if compared with other dry processes such as light emission, electron beam, corona, etc., the unique feature of the plasma cleaning machine is that its effect on the material only occurs on its surface. The thickness is in the range of ten to several thousand angstroms, and the effect on the surface of the material is not large. The above is a summary of the materials on the surface modification methods of vacuum plasma cleaner materials compiled by the editor.

Five major differences between commercial and industrial use of vacuum plasma cleaners

Five major differences between commercial and industrial use of vacuum plasma cleaners: Commercial vacuum plasma cleaners are very different from industrial plasma cleaners. So, where are these differences reflected? This article introduces the difference between vacuum plasma cleaners in commercial and industrial applications. 1. Under the same pressure and flow rate, the continuous effective working time of commercial equipment is much shorter than that of industrial equipment. 2. Commercial vacuum pump heads are generally made of copper or aluminum. However, the industrial pump head material must be made of alloy steel to meet the requirements. 3. The high rated working pressure for commercial use is far less than the high rated working pressure for industrial use. 4. Under the same pressure and flow rate, the pump head and the overall volume of a commercial vacuum plasma cleaner are much smaller than those of the industry. 5. Under the same pressure and flow conditions, the life span of commercial plasma cleaning equipment is much shorter than that of industrial plasma cleaning equipment.        The above is a summary of the information about the difference between commercial and industrial use of vacuum plasma cleaners compiled by the editor using time.

What substances are difficult to remove during the cleaning process of the vacuum plasma surface treatment machine

What substances are difficult to remove during the cleaning process of the vacuum plasma surface treatment machine

What substances are difficult to remove during the cleaning process of the vacuum plasma surface treatment machine: The vacuum plasma surface treatment machine, also known as the plasma surface treatment instrument, is a brand-new high-tech, which uses plasma to achieve effects that cannot be achieved by conventional cleaners. Plasma is a state of matter, also called the fourth state. Add enough energy to the gas to make it ionize and become a plasma state. In daily life, we must not only recognize the advantages of vacuum plasma cleaning technology, but also recognize its shortcomings and problems in use. Plasma cleaning also has some limitations in its application, which are mainly manifested in the following aspects: 1. In actual use, it was also found that plasma cannot well remove fingerprints attached to the surface, which is a common contaminant on glass optical components. Plasma cleaning cannot be used to completely remove fingerprints, but it needs to extend the processing time. At this time, it must be considered that this is the adverse effect it will bring to the substrate. Therefore, other cleaning measures must be taken to cooperate with the pretreatment, which makes the cleaning process more complicated. 2. Practice has proved that it cannot be used to remove grease stains. Although a small amount of grease stains on the surface of an object can be cleaned with a plasma method, the effect of removing grease stains is often not good. 3. This method cannot be used to remove the cutting powder on the surface of the object, which is particularly obvious when cleaning the grease on the metal surface. 4. Because the vacuum plasma surface treatment machine cleaning process requires vacuum processing, and is generally online or mass production, when the plasma cleaning device is introduced into the production line, the storage and handover of the workpiece must be considered, especially when the volume of the workpiece is large and This issue should be considered even more when the processing volume is large. In the cleaning process of the vacuum plasma surface treatment machine, the main issues that need to be paid attention to are the above points.

Solutions to 8 major application problems of plasma surface cleaning machine processing technology

Solutions to 8 major application problems of plasma surface cleaning machine processing technology: Regardless of whether it is in the production and research of industries, enterprises, colleges and universities, etc., products need to be cleaned, so how to solve the problem of dirt and impurities? Today, with the progress of the times, plasma surface cleaning machine processing technology has appeared in our lives. This is a brand-new high-tech technology that uses plasma to achieve effects that our conventional cleaning methods cannot achieve. Plasma surface cleaning What are the applications that the machine can solve? The following is an explanation of the processing method. ‘’ 1. The solution to clean the surface: The plasma surface cleaner is used to generate high-energy disordered plasma in the vacuum plasma chamber, and the surface of the product to be cleaned is bombarded by plasma to achieve the purpose of cleaning. 2. The solution to surface activation: Enhance surface energy, hydrophilicity, adhesion and adhesion to objects processed by the washing machine. 3. Treatment method of surface etching: The surface of the material is selectively etched by the reactive gas plasma. The etched material is converted into a gas phase and then discharged by a vacuum pump. After the treatment, the microscopic surface of the material increases and it has good hydrophilicity. 4. Nano coating processing method: After being processed by the plasma surface cleaning machine processing technology, the plasma-guided polymerization reaction forms a nano-coating. Various materials can be made hydrophobic (hydrophobic), hydrophilic (hydrophilic), lipophobic (anti-lipid), and oleophobic (anti-oil) through surface coating. 5. PBC manufacturing solutions: In fact, this is also a plasma etching process, which achieves the purpose of removing surface colloid by PBC by bombarding the surface of the object. The circuit board manufacturer uses the etching system of the plasma cleaner to decontaminate and etch, remove the insulating layer in the drilled hole, and improve the quality of the product. 6. Semiconductor/LED devices: The application of plasma in the semiconductor industry is that various components and connecting wires based on integrated circuits are very fine, so dust, organic matter and other pollution are prone to occur in the process. In order to avoid the problems caused by plasma in the process, Plasma equipment is introduced into the process for pre-treatment. The use of plasma cleaners is to better protect our products and to make good use of electrical equipment to remove organics and impurities on the surface. Pollutants can cause bubbles to form too quickly during the LED epoxy injection molding process, thereby reducing product quality and service life. Therefore, avoiding bubbles during the molding process is also worthy of attention. Using radio frequency plasma cleaning technology, the wafer and the substrate are more closely combined, so that the formation of colloidal bubbles is greatly reduced, and at the same time, the heat dissipation and light extraction rate can be significantly improved. The plasma cleaning machine is used for degreasing and cleaning of metal surfaces. 7. TSP/OLED solution: In terms of TSP: clean the main processes of the touch screen, improve the adhesion/coating force on OCA/OCR, laminate, ACF, AR/AF coating and other processes. Through the use of a variety of atmospheric pressure plasma forms, it can make All kinds of glass and films are discharged uniformly, so that the surface is not damaged and the treatment effect is good. 8. Vacuum plasma spraying solution: Because of the high energy density in the vacuum plasma surface cleaning machine, it can actually convert all powders with a stable molten phase into a dense and firmly adhered spray coating. The quality of the spray coating depends on the spray powder particles hitting. The instantaneous degree of melting on the surface of the workpiece. Vacuum plasma spraying technology has improved the production efficiency of modern coating machines.

Plasma surface treatment machine is used in the surface treatment of plastic fiber and polymer film

Plasma surface treatment machine is used in the surface treatment of plastic fiber and polymer film: Compared with metal materials, polymers have low density, low specific strength and specific modulus, corrosion resistance, simple molding process, low cost, good chemical stability, good thermal stability, good dielectric properties, low friction coefficient, and lubrication. Many advantages such as good performance and good weather resistance have been widely used in packaging, printing, agriculture, light industry, electronics, instrumentation, aerospace, medical equipment, composite materials and other industries. However, its application range and use effect are often limited by surface properties, so it is often necessary to improve or change its surface properties according to the purpose of use, such as the adhesion of materials or parts, the printing of polymer films, and water permeability. Need to use plasma surface treatment machine. In order to adapt to different application requirements, polymer materials generally adopt two methods. One of them is to generate a new surface active layer through various plasma surface treatment machine surface modification technologies, thereby changing the basic characteristics of the surface and interface. Another coating method is to use functional film or surface formation technology to coat the original surface. The purpose of both is to make the material have or have multiple surface properties at the same time. In response to this problem, people have researched and developed a variety of surface treatment technologies. Such as chemical wet method, drying treatment using electron beam or ultraviolet rays, addition treatment using surfactants and metal treatment by vacuum evaporation, etc. The dry treatment process of plasma surface treatment machine can change the surface structure and control the physical properties of the interface as required, and surface coating can also be carried out as required. Plasma surface treatment machine has broad application prospects in surface treatment of plastics, natural fibers, functional polymer membranes, etc.
