Application status of plasma cleaning machine in industrial cleaning equipment

Application status of plasma cleaning machine in industrial cleaning equipment

At present, there are three main types of industrial cleaning in the world, namely chemical cleaning, physical cleaning and biological cleaning. There are physical cleaning PIG technology cleaning, dry ice cleaning, ultrasonic cleaning, high-pressure water jet cleaning, plasma cleaning and other cleaning types. After years of research and practice, more and more users begin to look for and turn to physical cleaning methods. It can be said that physical cleaning technology is the development direction of world cleaning technology. Plasma cleaning machine is one of the physical cleaning equipment. Its working principle is that the plasma cleaning machine USES gas as the cleaning medium, which effectively avoids the secondary pollution caused by the liquid cleaning medium to the cleaned objects. A vacuum pump is attached to the plasma cleaning machine, and the plasma in the cleaning chamber gently washes the surface of the object to be cleaned when working. The organic pollutants can be thoroughly cleaned in a short time after cleaning, and the pollutants can be removed by the vacuum pump, and the cleaning degree reaches the molecular level. In addition to the super cleaning function, the plasma cleaner can also change the surface properties of some materials according to the needs under certain conditions. The plasma ACTS on the surface of materials, making the chemical bonds of surface molecules recombine and forming new surface properties. For some materials with special purpose, the glow discharge of plasma cleaner not only enhances the adhesion, compatibility and wetting of these materials, but also disinfuses and sterilizes them during the supercleaning process. Plasma cleaner is widely used in the fields of optics, optoelectronics, electronics, material science, life science, polymer science, biomedicine, microfluidics and so on. The application of plasma cleaning machine, originated in the early 20th century, with the rapid development of high-tech industry, its application is more and more widely, has been in many high-tech fields, in the status of the key technologies, plasma cleaning technology has a significant effect on industrial economy and industrial civilization, especially in the semiconductor and photovoltaic industry. Plasma cleaning machine has been used in the manufacture of various electronic components, we can be sure that, without the plasma cleaning machine and its cleaning technology, there would be no today so developed electronics, information and communication industries. In addition, the plasma cleaning machine and cleaning technology and application in the optical industry, machinery and aviation industry, polymer industry, industrial pollution prevention, control and measurement, and it is the key technology of product promotion, such as optical element coating, extend the life of the mold or machining tool abrasion resistance of the layer, the middle layer of composite material, weaving or recessive lens surface treatment, micro sensor smart, advanced mechanical processing technology, artificial joints, bones, or heart valve antifriction depletion are plasma technology progress, to complete the development. Plasma technology is a new field, the field combined with plasma physics, plasma chemistry and solid phase interface chemical reaction, this is a typical high-tech industries, across a variety of fields, including chemical, material and motor, so will be challenging, also full of opportunities, because of the fast development of semiconductor and photoelectric materials in the future have to leave the plasma cleaning. Cleaning machine nearly 20 years of research and development and promotion application, has achieved more successful experience. At present, there are two main reactions between plasma and material surface, one is chemical reaction by free radical, the other is physical reaction by plasma, which will be explained in more detail below. (1) Chemical reaction Commonly used gases in chemical reactions include hydrogen (H2), oxygen (O2), carbon tetrafloride (CF4), etc. These gases react in the plasma to form highly active free radicals, which will further react with the material surface. The reaction mechanism is mainly to use the free radicals in the plasma to do chemical reaction with the material surface. When the pressure is high, it is more favorable for the generation of free radicals. Therefore, if the chemical reaction is to be the main one, it is necessary to control the high pressure to conduct the reaction. (2) Physical reaction Mainly the ions in the plasma is used as a purely physical collision, the material on the surface of the atoms or attached on the surface of the material out, because the ions in the average pressure is lower free radicals is lighter, the accumulation of a lot energy, when the physical impact, the ion energy is higher, the more some impact, so

Application of plasma surface processor in pasting box machine

Application of plasma surface processor in pasting box machine

How to reduce pasting cost? How to solve the box pasting process in the phenomenon of glue? The answer is to use plasma surface processor to treat the paste box. Plasma surface treatment machine for pasting box after processing, the removal of organic pollutants on the surface of the joint and surface cleaning, laminating material surface changes a variety of physical, chemical, or produce etching and rough, or form a dense crosslinking layer, or the introduction of oxygen polar group, so that the hydrophilicity, cohesiveness, dyeing, biocompatibility, and electric property is improved. Under appropriate technological conditions after processing material surface, make the material surface morphology changed dramatically, introduced a variety of oxygen-containing groups, the surface from the nonpolar, difficult viscosity to have certain polarity, viscosity and hydrophilic, to improve the surface energy, the joint surface and no surface damage, not cause film coating or coating the surface of the spalling. The application of plasma surface processor in pasting box process has direct benefits as follows: 1. The product quality is more stable and will not be opened; 2. Reduce the cost of pasting box. If possible, ordinary glue can be used directly, saving more than 40% of the cost. 3. Directly eliminate the impact of paper powder and wool on the environment and equipment; Improve work efficiency. Originally in order to package the printed matter in the circulation process is not rubbed against the flower, in order to improve the waterproof function, or to improve the product class, etc., in the printing packaging process, will do a layer of protection on the surface of the printed matter, some on a layer of varnish, some covered with a layer of film, etc. Glazing process UV glazing relatively more complex, there may be more problems. At present, because of the poor affinity between UV oil and paper, resulting in paste box or paste box often appear when the phenomenon of glue. And after laminating, due to the surface tension of the film and surface can have different values under different conditions, the size is suddenly different, plus different brands of glue show different adhesion, also often appear glue phenomenon, and once the product is handed over to the customer when glue, there will be the possibility of being fined. All of these make each manufacturer more worry, some customers in order to reduce the above situation as far as possible, not hesitate to increase the cost of purchasing imported or domestic high-grade paste box glue, but if the improper storage of chemicals, or other reasons, sometimes there will still be open phenomenon. In the traditional process, in order to effectively deal with the phenomenon of glue opening, each box pasting machine factory is equipped with edge grinding machine in their own each box pasting machine, the mouth part of the UV light paste tongue grinding, temporarily deal with the problem of glue opening. And the film coated products can not be polished with a grinding wheel, then use the method of cutting teeth line, or in the film cover to get out of hand position, and then with high quality glue, but this is not an effective solution. Although polishing the life while pasting the box is an effective solution to the bonding problem, the following problems still exist: 1. Part of the paper wool paper powder that is ground during grinding will pollute the surrounding environment of the machine and increase the wear of the machine and equipment; 2. Since the linear velocity direction of grinding wheel movement is opposite to the direction of product operation, it is bound to affect the operation speed of some products and reduce work efficiency; 3. Although the coating to wear, but only UV coating and a small amount of paper surface coating, for high-grade medicine boxes and cosmetics boxes and other products, the general manufacturers do not dare to use ordinary glue to stick the box, so, paste box cost will not be too low.The situation is better than UV products, but the plastic film to make life on the small box products can not be used, the tooth line will also appear process problems, increase the cost of knife version.

Plasma surface treatment equipment for a variety of industry applications

Plasma surface treatment equipment for a variety of industry applications

Plasma surface processor is widely used in printing and packaging, silicone rubber products, glass precision, wire and cable, digital electronics, automobile manufacturing, medical biology, textile industry, composite materials and new energy, almost all the industrial fields of mechanical equipment. Generally, the particle energy in the low-temperature plasma is about several to a dozen electron volts, which is larger than the bonding energy of polymer materials (several to a dozen electron volts). It can break the chemical bonds of organic macromolecules and form new bonds, but it is far lower than high-energy radioactive rays. It only involves the material surface and does not affect the performance of the matrix. The thermodynamic equilibrium conditions of low temperature plasma, electron has high energy, can fracture of material surface molecular bonds, improve particle chemical reactivity (more than hot plasma), and neutral particles temperature close to room temperature, these advantages for heat-sensitive polymer surface modification provides appropriate conditions. Through low temperature plasma surface treatment, a variety of physical and chemical changes take place on the surface of the material, or etching and rough, or forming a dense crosslinking layer, or introducing polar groups containing oxygen, so that hydrophilicity, adhesion, coldability, biocompatibility and electrical properties can be improved. Plasma-treated paste box material: with OPP, PP, PE coated cardboard; Cardboard with PET coated film; Plasma processor: ★ Board with metal coating; ★ Cardboard with UV coating (UV oil curing itself can not be delaminated); ★ Impregnated cardboard; ★PET, PP transparent plastic sheet, etc.   Plasma equipment in the printing industry: Application of plasma surface processor in printing and packaging industry: using plasma surface processor to treat cementing surface process can improve bonding strength, reduce cost, stable bonding quality, good product consistency, no dust generation, clean environment. It is the solution to improve the product quality of pasting box machine.

Its processing effect has been recognized and recognized by famous printing companies at home and abroad.   Plasma equipment in the digital industry: Plasma surface processors in the digital industry: Plastic as a new material to replace metal, the surface paint is not easy, consumers often bought mobile phones, laptops or digital cameras less than a month after the surface paint or keyboard fade problems. If treated by other chemical methods, the price is high and the pollution is high. While the use of digital dedicated plasma processor processing surface color slightly lighter, the reverse luminosity reduced, touch can feel the surface slightly rough; The adhesion property of spray paint is greatly enhanced. Plasma surface processors are already widely used in nokia, Apple, Konka and other mobile phone cases and keyboards.   Plasma surface processors in the automotive industry: Application of plasma surface processor in automobile industry: at present, it has been widely used in car lights, various rubber seals, interior decoration, brake block, wiper, oil seal, instrument panel, airbag, bumper, antenna, engine seal, GPS, DVD, instrument, sensor. Car door seals: if you want to paint or flocking on its surface, because its material is mostly rubber products, it is not easy to stick. An on-line plasma processor is the ideal solution if chemical cleaning is not only off-line but also polluting the environment. In the treatment of automobile lamps, the cementation is used to meet the leakproof requirements between the mirror and the shell. The surface of the cementation is pretreated with the plasma surface processor, and the result of the cementation is cheap and high quality, which is closely combined with the production line to achieve continuous production. At present, it has passed the treatment of byd, Chrysler, GENERAL Motors, Audi and other vehicles, with remarkable results. To be the first choice of most well-known auto manufacturers or auto parts suppliers in China.   Plasma-bonded cell phone case: In order to make the appearance of mobile phones more sophisticated, mobile phone cases are usually glued together or printed with brand logos or decorative strips. The previous mobile phone shell is composed of ABS, its surface tension is high, generally do not need to deal with. But with the wide use of PC, nylon + fiberglass and other materials, no treatment can no longer increase the surface tension of the substrate to the required value of glue.

Principle of plasma-cleaning machine to remove glue

Principle of plasma-cleaning machine to remove glue

Operation method of plasma adhesive removal: Insert to film quartz boat and parallel airflow direction, into the vacuum chamber between the two electrodes, vacuum to 1.3 Pa, ventilation with suitable amount of oxygen, maintain reaction chamber pressure in 1.3-13 Pa, and high frequency power, produce lavender glow discharge between the electrodes, by adjusting the power, flow and other process parameters, can get different stripping rate, when the film to the net, glow disappeared. Influencing factors of plasma degumming: Frequency selection: The higher the frequency, the easier it is for oxygen to ionize to form plasma. If the frequency is so high that the electron amplitude is shorter than its average free path, the probability of collision with the gas molecule will be reduced and the ionization rate will be reduced. The commonly used frequencies are 13.56MHz and 2.45GHZ. Power influence: For a certain amount of gas, the power is large, the density of active particles in the plasma is also high, and the removal speed is fast. However, when the power increased to a certain value, the reactive ions consumed by the reaction reached saturation, and no matter how high the power, the removal rate did not increase significantly. Due to the large power and high substrate temperature, the power should be adjusted according to the process needs. Selection of vacuum degree: if the vacuum degree is improved properly, the average free path of electron motion can be enlarged, so the energy obtained from electric field is large, which is favorable for ionization. In addition, when the oxygen flow is constant, the higher the vacuum degree is, the greater the relative proportion of oxygen will be, and the higher the concentration of active particles will be. However, if the vacuum degree is too high, the concentration of active particles will decrease. Influence of oxygen flow: high oxygen flow, high density of active particles, and faster degumming rate; However, if the flow rate is too high, the probability of ion recombination will increase, the average free path of electron motion will shorten, and the ionization strength will decrease. If the pressure of the reaction chamber remains unchanged and the flow rate increases, the amount of gas extracted also increases, and the amount of active particles that have not yet participated in the reaction also increases accordingly. Therefore, the effect of the increase of the flow rate on the degumming rate is not obvious.

What is a vacuum plasma? Vacuum plasma is formed by ionization in a gas vacuum chamber. Oxygen and argon plasmas are mostly used to clean, etch or activate material surfaces. Plasma treatment has been around since the early 1970s and is often used to clean organic impurities and contaminants on material surfaces. Plasmas perform well in etched circuit boards and other electronic products. What is plasma processing? Plasma treatment is the use of a controlled vacuum plasma to change the surface of a material to improve adhesion, printing, painting, coating or wettability. The process is carried out in a plasma chamber under vacuum pressure. Plasma treatment is often used in the manufacture of electronic equipment, medical equipment, textiles, plastics, rubber, etc. Almost all dry materials can be treated in a plasma chamber. Plasma treatment can change the surface performance of materials to improve the surface energy, bonding performance, printing or wettability. Plasma treatment can also achieve waterproof properties by covering the product. Almost all materials can be treated with plasma technology. We have developed a full line of products for manufacturing, research and development, and academic applications. All surfaces contain organic contaminants, although they are not normally observed.

How is the plasma cleaning machine surface treatment technology efficient surface cleaning

How is the plasma cleaning machine surface treatment technology efficient surface cleaning

Plasma pretreatment and cleaning creates ideal surface conditions for subsequent coating of plastics, aluminum and even glass. How is the plasma cleaning machine surface treatment technology efficient surface cleaning? As plasma cleaning is a "dry" cleaning process, the material can immediately enter the next processing process after the treatment, therefore, plasma cleaning is a stable and efficient process. Due to the high energy of plasma, the chemical substances or organic pollutants on the surface of the material can be decomposed, and the impurities that may interfere with adhesion can be effectively removed, so that the surface of the material can meet the requirements of the subsequent coating process. The use of plasma cleaning machine plasma technology according to the requirements of the process for surface cleaning, no mechanical damage to the surface, no chemical solvent green environmental protection process, mold release agent, additives, plasticizer or other hydrocarbon composed of surface pollution can be removed. Surface cleaning by plasma cleaning machine removes fine dust particles that are tightly attached to the plastic surface. Through a series of reactions and interactions, the plasma is able to remove these dust particles from the surface of the object. This can significantly reduce the rejection rate for high quality coating operations such as those in the automotive industry. Through a series of physical and chemical actions at the microscopic level, plasma surface cleaning can obtain fine and high-quality surfaces. Advantages of plasma cleaning: 1. Compared with plasma cleaning, water washing is usually just a dilution process. Compared with CO2 cleaning technology, plasma cleaning does not need to consume other materials. 2. Plasma cleaning can deal with the complete surface structure of the material, not just the protruding part of the surface layer. 3. Online integration without extra space; Low operating cost, environmentally friendly pretreatment process. 4. Pretreatment: Plasma surface activation treatment for different applications. Plasma surface treatment technology can be used for surface activation of a variety of materials, including plastics, metals, glass, textiles, etc. Whether coating or bonding is required on the treated surface, effective activation treatment of the material surface is a necessary process step. By measuring the surface with a surface test ink: Before treatment, the surface tension is low, the test ink can not wet the surface, after plasma treatment, the surface tension is increased, the test ink can wet the surface, the activation effect of plasma treatment on the surface. Plasma surface treatment can effectively activate the surface of the material. For plastics, non-polar surface is often difficult to be bonded and coated, and the activation of the surface is to modify the structure of the polymer molecular chains that constitute the plastic, making the surface of the material easy to be processed and treated Advantages of CRFPLASMA activation: The process is fast and reliable; Uniform plasma beam ensures uniform and stable surface treatment, low-cost, environmentally friendly pretreatment process; Pretreatment process without corona effect; The material is treated without contact with high voltage.    Pretreatment: plasma technology and plasma coating technology, a surface coating technology of unlimited application potentials for using plasma technology or plasma coating technology, can satisfy the demands of subsequent process various features can make the surface with the aid of this novel plasma technology, using low cost of material, can produce a new type of high quality materials, high functional. Plasma coating technology is very suitable for selective coating treatment, which greatly expands the application field of this technology. PET film, aluminum foil, textiles, glass, various plastics, metals and precious metals can be used to finish the surface coating treatment. Using this technique, it is also possible to harden the material, for example in tool manufacturing, or to produce plastic products with sticky or self-adhesive surfaces. Sing Fung Intelligent  Manufacturing: plasma cleaning machine plasma processing to ensure reliable coating adhesion. In practical production, the manipulator is often used to control the plasma spray gun for surface treatment of products. Typical applications of plasma pretreatment technologies include automobile and aviation industries, manufacturing of electronic and electrical appliances, daily necessities and packaging industries. Plasma cleaning machine pretreatment can ensure the adhesion of surface coating on metal materials such as aluminum, plastic materials such as PP or EPDM, or other materials. Process: plasma processing technology is used to achieve reliable and durable bonding qua
