What are the unexpected effects of using wide-format plasma equipment? Let's take a look at it together

What are the unexpected effects of using wide-format plasma equipment? Let's take a look at it together

What are the unexpected effects of using wide-format plasma equipment? Let's take a look at it together: The wide-width plasma equipment adopts digital control technology, which has a high degree of automation; the control equipment has high precision and good control of time; the correct cleaning method will not cause damage to the machine and can extend the service life of the machine; and it is in the atmospheric environment Cleaning will not cause secondary pollution to the environment, so what are the advantages of using a wide-format plasma equipment for plasma cleaning? The wide-format plasma equipment will be dried after cleaning, and then the next process can be carried out, which can effectively improve the processing efficiency. Application effect of wide-format plasma equipment: 1. Improve the surface adhesion ability and improve the reliability and durability of surface adhesion. 2. After the atmospheric pressure plasma treatment is used, the surface energy of materials such as various polymer plastics, ceramics, glass or metals have been improved. 3. Through such a treatment process, the surface tension performance of the product is improved, and it is more suitable for processing requirements such as coating and bonding in the industry. 4. The processing surface can be customized according to the customer, and a large area can be processed at one time, making the processing easier. The wide-format plasma equipment technology has the following characteristics: 1. The wide-width plasma equipment can process materials with a width of 1-3 meters, which can meet the surface treatment requirements of most existing industrial materials. 2. High uniformity: The atmospheric pressure plasma is a glow-type plasma screen, which directly acts on the surface of the material. Experiments have shown that the same material can be processed at different positions with high uniformity. This feature is important for the continuous casting, Processes such as coating and printing are of great significance. 3. Low cost: The gas pressure plasma equipment has low energy consumption, and the operating cost is mainly gas. Take the consumption gas argon as an example, its consumption is less than 1/20 of the consumption of corona plasma gas. 4. Safe and convenient to use: Atmospheric plasma, also known as low temperature plasma, does not damage the surface of the material. No vacuum chamber, no arc, no harmful gas suction system, long-term use will not cause harm to the operator's body. 5. The effect is controlled: There are three effect modes for the large-width plasma equipment plasma to choose from. First, the choice of argon/oxygen combination is mainly for non-metallic materials, and has higher requirements for treatment effects. Secondly, choose the combination of argon/nitrogen, mainly for areas where there are unprocessable metals in the product to be processed. In this solution, due to the strong oxidation of oxygen, the problem can be controlled after replacing nitrogen. Thirdly, using only argon gas, the surface modification can also be achieved using only argon gas, but the effect is relatively low. This situation is rather special, and it is a scheme adopted by some industrial users when they need to perform uniform surface modification at the same time.

Plasma surface modification of bast fiber in atmospheric plasma cleaning equipment

Plasma surface modification of bast fiber in atmospheric plasma cleaning equipment

Plasma surface modification of bast fiber in atmospheric plasma cleaning equipment: During the plasma treatment of fibers and polymers by the atmospheric plasma cleaning equipment, the high-energy particles and photons generated by the plasma interact violently with the surface of the substrate, and this interaction usually manifests as a free radical chemical reaction. Generally, four surface effects can be observed, namely, surface cleaning, surface etching, molecular cross-linking near the surface, and changes in surface chemical structure. To a certain extent, each effect may exist, but one of the effects may be more obvious than others, depending on the processing object, the chemical properties of the gas, and the instrument model and the settings of the instrument parameters. Several surface effects, alone or in synergy, will affect the adhesion of the processed object. Plasma treatment of atmospheric plasma cleaning equipment has a very good effect on improving the bonding strength between polymer and fiber and between polymer and polymer. The increase in adhesion after plasma treatment is due to the increase in the wettability of the substrate and the change in the chemical structure of the polymer surface after treatment. The gas generates a plasma medium under the coupling action of electromagnetic force. This plasma medium contains ions, electrons, neutrons, photons, free radicals, metastable excited particles and molecules, and dynamic mixing at room temperature. Plasma treatment can make The surface of fibers and textiles is functionalized without affecting their overall performance. Under the action of electromagnetic field, these plasma particles diffuse into the surface of the fabric substrate in a gradient, resulting in a variety of general surface treatments, including surface activation of active sites due to bond breakage, grafting of chemical structures and functional groups, and material volatilization Removal (etching), surface contaminants or layer dissociation (cleaning), and deposition of conformal coatings, etc. The electron collision and photochemical molecular separation of atmospheric plasma cleaning equipment will generate plasma containing high-density free radicals, which can cause the chemical bonds on the surface of the fiber polymer to break, thereby forming new chemical substances on the surface of the fiber polymer. This will lead to changes in the chemical structure and morphology of the fiber surface. The specific surface area of ​​the fiber will increase significantly. Plasma treatment on the surface of fibers and polymers will lead to the production of new functional groups such as hydroxyl (-OH), aldehyde (-CHO) and carboxyl (-COOH), which affect the moisture absorption of the fabric and facilitate the grafting of molecules deal with. The unique physical and chemical properties and temperature range characteristics of plasma. Make it an effective tool for surface treatment of materials. The low-temperature plasma treatment of atmospheric plasma cleaning equipment can improve the dyeing rate, dye uptake and color yield of linen fabrics. The etching and oxidation of the hemp fiber surface reflects the effect of plasma treatment. For fiber products with low color fastness, low-temperature plasma dyeing can be considered. Satisfactory dyeing results can usually be obtained. Plasma treatment can achieve effects that cannot be achieved by conventional treatment. Plasma can only act on the surface of the substance (the upper layer) instead of the entire material. The high cost of the treatment process can be repaid by high value-added products. The application space of plasma technology is huge. Generally speaking, the development of plasma technology in the industrial revolution is relatively slow, but it can develop steadily.

What role does the low-temperature plasma cleaning machine play in the production and manufacture of power lithium batteries

What role does the low-temperature plasma cleaning machine play in the production and manufacture of power lithium batteries

What role does the low-temperature plasma cleaning machine play in the production and manufacture of power lithium batteries: Power lithium battery is a commonly used lithium battery powered by pneumatic tools. This is a clean and environmentally friendly drive power supply. In today's application scenarios, it is widely used in pure electric vehicles, electric trains, electric vehicles and golf carts. In recent years, with the rise of the new energy vehicle sales market, the safety and reliability of power lithium batteries has become a topic of concern and discussion. The reason is not only that the power lithium battery is a key component of the power drive system software, but also that the power lithium battery production process itself has high reliability and reliability requirements. Taking automobile lithium batteries as an example, what role can low-temperature plasma cleaning machines play in the manufacturing process of power lithium batteries? What assistance can be provided for them? In the production process of automobile power lithium battery, the surface treatment of low-temperature plasma cleaning machine is generally carried out from three levels, that is, to improve the lubrication performance of the ceramic film before coating the positive and negative plates; to clean the connecting piece before lithium electric welding; and Improve the surface adhesion of insulating plates, end plates, PET plastic films and other metal composite materials and their insulating materials before external gluing of their lithium battery components. 1. Low-temperature plasma cleaning machine solves the problem of positive and negative two-stage coating before ceramic membrane plasma cleaning machine: The positive and negative stages of the power lithium battery for automobiles are made according to the positive stage of the ceramic film and the battery cathode material. Compared with cleaning with ethanol and other aqueous solutions, plasma cleaning machine treatment will not damage the material itself, and can remove organic matter on the surface of the raw material, improve the lubricity of the film surface, and improve the uniformity, heat resistance and safety factor of the coating. 2. Plasma cleaning before welding: The lithium tab actually refers to the part between the positive and negative stages of the metal material strip that correctly guides the rechargeable battery. It is a point contact type during battery charging and charging and discharging. Whether the surface of the connecting piece is clean or not has a great hazard to the reliability and performance of the electrical connection. Treatment with a plasma cleaner before electric welding can remove organic matter, particles and other residues on the surface of the weld, make the surface of the weld uneven, and improve the quality of steel lap welding. 3. Low-temperature plasma cleaning machine to process the raw rubber of lithium battery components: The lithium battery assembly process is to connect several rechargeable battery modules in series into a series of parallel circuits to produce a lithium battery pack. In order to maintain the safety of the power supply circuit and the insulation layer, during this process, a rechargeable battery must be attached to the outside to improve the safety factor of the application. Prior to this, please use a plasma cleaning machine to clean the insulating plates, end plates, PET film and other parts. Plasma treatment can thoroughly clean the dirt surface, make the surface matte, and improve the adhesion of super glue or super glue.

Tips for distinguishing between radio frequency plasma cleaner and intermediate frequency plasma cleaner

Tips for distinguishing between radio frequency plasma cleaner and intermediate frequency plasma cleaner: The intermediate frequency plasma cleaner is an intermediate frequency. The 40KHz intermediate frequency power supply uses 16-bit microprocessor as the core, power electronic devices as the power output unit, and adopts new technologies such as digital frequency division, phase lock, waveform instantaneous feedback, SPWM pulse width modulation, IGBT output, etc. , And adopts a modular structure, with strong load adaptability, high efficiency, good stability, good output waveform quality, simple operation, small size, light weight, intelligent control, abnormal protection function, adjustable output frequency, fast output response , Strong overload capacity, fully isolated output, long life, good damage resistance. This kind of power controller is used on intermediate frequency ion equipment. RF plasma cleaners use RF power, that is to say, the difference between our intermediate frequency plasma cleaner and RF plasma cleaner lies in the matching power they use. RadioFrequency, or RF for short. RF is RF current, which is an abbreviation for alternating high-frequency electromagnetic waves. The alternating current is called low-frequency current when it is below 1000 per second, and it is called high-frequency current when it is above 10000. The radio frequency current is this kind of high-frequency current. Therefore, we will easily distinguish between these two types of equipment.
