Application of plasma surface processor in textile processing

Application of plasma surface processor in textile processing

Textile industry is one of the industries with a long history of mankind, and also an important part of the industrial revolution. For a long time, in order to adapt to the changing consumer changes and cope with the increasingly severe environmental pressure, the textile industry has been developing and making progress. Textile plasma surface treatment technology is developing rapidly in China. The early plasma surface treatment technology has been replaced by new atmospheric plasma surface treatment technology. This new technology can improve the performance of a fabric by changing its surface properties. Development Trend of textile Industry: The textile industry provides a large number of jobs, creates a lot of wealth, and also has a huge impact on many industries, including mechanical engineering, polymer materials, chemistry and fuel. Since the 1990s, market drivers have included design and innovative fabrics, as well as increased investment in new technologies by industrialized countries to reverse the long-term decline of their textile and clothing industries. Earlier, the newly industrialised countries of East Asia that had succeeded in entering western markets were beginning to find their places being taken by a new generation of developing countries. In the whole textile industry chain, the competition between enterprises and western countries is increasingly intensified. Most countries with developed garment industry have established r&d centers, which are engaged in extensive improvement research and basic research work. Textile plasma surface treatment: The textile industry has long recognized that the surface performance of fabrics is a critical factor in many processing processes and applications, and the specific requirements for the surface performance of fabrics are often very different from that of base fabrics. The surface properties of the fabric not only determine the dyeing rate and color fastness of the fabric, but also determine the simplicity of the finishing process of the fabric, determine the binding strength between the coating and the base cloth, and play a crucial role in the biocompatibility between the coating and the base cloth. In addition, surface properties play a key role in the disinfection performance and biocompatibility of medical implants requiring liquid chemical treatment. Conventional textile processing technology consumes a large amount of energy and water resources in the processing process, causing serious water pollution, high cost and environmental damage. In the conventional fabric treatment process, the surface treatment of the fabric is carried out at the same time as the base fabric treatment, which will adversely affect the overall performance of the fabric. Therefore, the textile industry urgently needs to choose alternative surface treatment technology to reduce production costs, protect the environment, and produce new products with long life, high quality and good performance. Certain properties of fabrics can be adapted to meet specific needs by changing the function or shape of the fabric surface. By etching the fiber surface, cracks and cracks can be created on the fiber surface. This etching can help enhance the wettability of the fabric, thus achieving more effective dyeing or deep dyeing. Conversely, by reducing the wettability of the fabric can be achieved waterproof effect. The new chemical function of fabric surface can promote the reaction between fabric surface and dyes, thus greatly improving the adhesion between layers. It is a very complicated process to change the surface property of fabric by plasma surface treatment. The reactions initiated by the particles in the plasma usually occur at a depth of 10nm from the surface of the material. The radiation caused by short-wave ultraviolet radiation in the plasma is very deep, within 100nm of the surface. The working gas and other process parameters of plasma can change the interaction and range of action between the two reactions. The outermost layer of the fabric is only a few atoms thick, usually less than 1nm, but it determines how the fabric interacts with other media. The chemical composition of the outermost layer of the fiber surface determines the interlaminar bonding ability of the fabric and the suitability of the fabric for impregnation. The outermost layer of the fiber chemical structure and composition can be modified by plasma. The fabric surface treatment not only needs to choose the appropriate process parameters, but also the original surface performance of the fabric is also important. At present, plasma surface treatment technology has been applied to the surface modification of textiles and the modification of base fabrics, which has successfully improved many kinds of fabrics from traditional fabrics to advanced composite fabrics. The results show that the surface energy of fiber and fabric can

Whether the plasma cleaning machine can remove surface oil stains

Plasma cleaning machine, surface modification, etching activation equipment widely used in plasma surface activation/cleaning; Plasma-treated bonding; Plasma etching/activation; Plasma degumming; Plasma coating (hydrophilic, hydrophobic); Enhanced bonding; Plasma-ashing, surface modification and other occasions, through plasma treatment, can improve the surface of the material wettability, so that a variety of materials can be coated, etching, printing and other operations, enhance the bond strength, while removing organic pollutants, oil or grease. In plasma, the active particles can effectively activate the dirt on the surface of the object to achieve the purpose of cleaning, that is, plasma cleaning. For the plasma cleaning machine, the plasma adsorption on the surface of the cleaning material, the reaction between the cleaning material and the plasma occurs, produce new molecules, so as to further promote the formation of new molecules into gaseous molecules, remove oil and other dirt on the sticky film. Plasma cleaning machine cleaning is different from traditional wet cleaning. Plasma cleaning is dry cleaning, the whole process of cleaning once, no residue. At the same time, it can improve the adhesion of the substrate surface membrane. The cleaning process is easy to control, easy to operate, highly efficient, and the cleaning time and gas (if necessary) can be controlled. According to our experience, to remove metal oil stains, we need to use the active group of plasma to react with oil stains to achieve the purpose of cleaning. We choose vacuum plasma cleaning machine as the test equipment. The method to judge the cleaning of metal oil stains is to drop a drop of distilled water into the metal surface with a pipette, observe and compare the shape and diffusion of water droplets on the metal surface before and after cleaning, and judge the cleaning result of oil stains. This method is fast and simple, and can be clearly judged by naked eyes. It is an effective means to judge the cleaning effect of metal oil stains. Tools/raw materials. 1. Clean the tweezers. 2. Put 50ml distilled water into a beaker. 3.100ul-500ul pipette. 4. Three heavy greasy metals, three light greasy metals, and three clean metals. Vacuum plasma cleaning machine. Methods/steps. Step 1: Use tweezers to remove a heavy, greasy metal and place it on a clean piece of white paper. Step 2: Adjust the pipette to a scale of 100UL, draw distilled water from the beaker, drop a drop of distilled water slowly on the heavy metal, and observe the shape and spread of the water droplets. Step 3: Take out the second heavy greasy metal with tweezers, put it on the appropriate tray, open the cavity door, put the tray and heavy greasy metal into the cavity of the vacuum plasma cleaning machine system (ensure that the placement position is horizontal and the metal is not easy to slide off), and close the cavity door. Step 4: Click the parameter setting of the touch screen to set the cleaning time. Press the start button. After about 30 seconds, the glow will start. Step 5: Wait for the end of cleaning time and pressure relief, open the door, take out the cleaned metal sample with tweezers, and put it on the white paper. Step 6: Use a pipette to slowly drop a drop of distilled water on the heavy greasy metal, and carefully observe the shape and spread of the water droplets. Finally, compared with the test results, the droplet on the metal surface before cleaning is circular, forming a droplet with a contact Angle of about 90 degrees, and the metal is hydrophobic before cleaning. After using the plasma cleaning machine, the pipette drops the water onto the metal surface, the water droplets immediately disperse, the contact Angle is significantly reduced, and the metal surface's spreading ability to water, namely wettability, is significantly improved, indicating that the metal hydrophilicity is improved, and the metal is cleaner after the plasma cleaning.

Plasma cleaning instrument PDMS

Plasma cleaning instrument PDMS

Polydimethylsiloxane, or PDMS for short, is an organosilicon polymer, plasma cleaning device cleaning PDMS is widely used at home and abroad. All organosilicon have a common siloxane unit, which is composed of one siloxane group. Many side groups can bind to silicon atoms, and PDMS of these side groups are CH3 methyl groups. Si-sh3 is the most common polymer, and its content is also high. A short molecule consisting of only two terminal groups (without dimethylsiloxane monomer units) is hexamethyldisiloxane, which is very important as a process gas for hydrophobic plasma coating plasma cleaning apparatus. PDMS is a linear polymer with a very large molecular weight and is liquid. But it binds to each other and thus has elastic properties. PDMS is a nearly inert polymer with high oxidation resistance that can also be used as an electrical insulating material (microelectronics or polymer electrons) in organic electronics, as well as in biological microanalysis. One of the most common applications for PDMS is in the field of microfluidic systems, where specified polydimethylsiloxane (e.g. Sylgard184) is structured upon request, plasmacytreated, and PDMS chips are permanently coated on glass panels, silicon surfaces, or other substrates. Advantages of pretreatment of plasma cleaning instrument for microflow system: Shorten processing time; PDMS is permanently attached to the substrate surface to form a non-permeable channel of the microfluidic element. The substrate surface of PDMS and hydrophilicity, and thereby completely wetting the channel; Form hydrophilic and hydrophobic waters.

Plasma cleaning machine to increase the surface viscosity of materials

Plasma cleaning machine to increase the surface viscosity of materials

Plasma cleaning machine is the key technology of ultra-fine environmental cleaning, surface activation and plasma coating. Plasma cleaning machine can not only clean and remove dirt, but also improve the surface performance of the material itself. For example, to improve the surface wettability, increase ink, coating, coating adhesion, enhance the material's surface energy, hydrophilic. Adhesiveness refers to the stability of the connection or combination between the substrate and the adhesive coating. The separation force is the standard for bonding performance and is directly applied to the separation force value during bonding (peel test, end force test). Plasma cleaning machine can improve the surface adhesion of materials, is a very environmentally friendly treatment method. If the binding force is higher than the adhesion strength of one of the two bonds, the adhesion performance is better. If the separation of attachment is not caused by the dissolution of the compound but by the fracture of the material in a pair of complexes, then the above situation is corresponding. If the coating material (paint, adhesive) completely wet the substrate, it can achieve good adhesion. Wettability can usually be determined by: Check ink; LABS testing; Contact Angle measurement. No matter what kind of substrate or coating, the basic use of plasma cleaning machine must be pretreated, the purpose is to get enough adhesion, because there are always some factors will affect the adhesion. Preprocessing includes at least one or more of the following sets of steps: Cleaning: especially for the removal of hydrocarbons (mold release agent, oil, grease, etc.), the plasma cleaning machine can be used for processing, can completely remove such substances, so as to improve the surface adhesion. Plasma activation: in order to completely bond the coating, the surface of the substrate must be greater than the surface tension of the coating. The surface energy can be increased by plasma activation, and almost every material combination can achieve complete binding. Increase surface area: A rough (clean, active) surface is much better than a smooth (smooth) surface. Through plasma treatment coarsening, surface roughness (increase surface area) can be realized, so as to realize frosting and sandblasting processing. Corrosion: chemical etching, plasma etching, micro-sandblasting. Oxidation removal: By plasma treatment, the oxide layer on the material surface is also removed.

Advantages and disadvantages of atmospheric plasma cleaning machine

Advantages and disadvantages of atmospheric plasma cleaning machine

Compare the advantages and disadvantages of atmospheric plasma cleaning machine, first of all under the contrast of the vacuum plasma cleaning machine, atmospheric plasma cleaning machine is the biggest advantage of the environment does not need low pressure, and can be made into a variety of online design, integrated in the customer's production line. Atmospheric pressure plasma cleaning machine advantages: Plasma activation can be carried out directly on the conveyor belt; Suitable for in-line processing without the use of vacuum technology; For example, a very thin layer of oxidation (passivation) can be produced when the aluminum is processed by plasma cleaning equipment. Local surface treatment may be performed (e.g. bonding slots); Objects can be processed directly on the conveyor belt; Disadvantages of atmospheric atmospheric plasma cleaning machine: Because of the principle of plasma excitation, the traces left by plasma treatment are very limited (about 8-12 mm). When operating with large objects, multiple nozzles or multiple nozzles types (such as a combination of direct and rotary) must be used, depending on customer requirements and production capacity. The plasma cleaning of easily oxidized objects is limited. For 3D products, which require complex multi-joint robot technology, the clearance penetration of plasma at high atmospheric pressure is limited to some extent. Atmospheric plasma scrubber is generally only suitable for planar treatment. In addition, the processing surface is single, if two surfaces are to be processed at the same time, the process is more complex. When processing, the object must be positioned on the conveyor belt very precisely. The nozzle movement trajectory of atmospheric plasma cleaning machine can be set. However, the object to be processed must be fixed on the moving platform, or it can be determined according to the requirements of customers.

Lithium battery plasma cleaning machine processing process

Lithium battery plasma cleaning machine processing process

At present, lithium batteries are mainly used in electronic and digital products, including tablet computers, laptops, mobile phones, digital cameras and other products. Plasma cleaning machine plays a vital role in the manufacture of lithium batteries. With the rapid development of electric vehicles and the gradual rise of energy storage industry, these two fields will also be the focus of lithium battery development in the future. As for the electronic industry, after years of rapid growth, electronic and digital products are expected to show a steady growth trend in the future. With the development of electronic and digital products towards portability, higher requirements have been put forward for battery products, and the battery industry will correspondingly develop towards high energy density, large capacity and light weight. The reliability of the power battery pack is very high, not only to stable discharge, but also to ensure that all the welding line does not fall down, so the welding line welding position is particularly important. Each welding line should be inspected according to national standards, more importantly, in the welding stage to improve the adhesion, so that the welding wire is firm. Cell processing is an important part in the production and assembly process of vehicle power lithium ion batteries. Cell processing includes edge sealing and pole ear leveling. After leveling the polar ear, use a plasma cleaning machine to clean it, which can remove organic matter and small particles and improve the reliability of subsequent laser welding. The vehicle used in the power of lithium batteries is divided into positive and negative, positive and negative from the metal strip leading out of the cell, colloquially said, the battery positive and negative is the contact point when charging and discharging. Whether the contact surface is clean will affect the reliability and durability of the electrical connection. In the production process, the pole ear of lithium battery cell is often uneven, bent or even twisted, which leads to false welding, false welding, short welding and other phenomena during welding. After leveling the electrode ear, impurities such as organics and particles are removed from the electrode ear surface by plasma cleaning machine, so as to make the weld surface roughened, which can ensure good weld effect of the electrode ear. Introduction to the technological process and advantages of the plasma cleaning machine: I. Lithium battery cell core plasma cleaning machine Processing flow: Core feeding → pole ear leveling → plasma cleaning → front side of the core → reverse side of the core → plasma cleaning → core discharging Two, plasma cleaning machine advantages; Plasma cleaning is to excite compressed air or process gas into plasma through high frequency and high pressure, and then conduct physical or chemical reactions with organic matter and small particles to form a clean and slightly roughened surface with no residue after thorough cleaning. The use of plasma cleaning cost is low, almost no waste gas, green environmental protection; Plasma cleaning machine can be installed on the assembly line, and other automatic equipment seamless docking, easy to operate and monitor. Plasma cleaning is a dry cleaning, relying on the active ion in the plasma "activation" to achieve the purpose of removing stains. This method can effectively remove the dirt, dust and other substances on the end face of the battery pole column, prepare for the battery welding, and reduce the bad welding.
