1.Comparison of ceramic electrode and metal electrode
Ceramic electrode and metal electrode corona have their own advantages and
disadvantages:
1)Ceramic electrode discharge uniformity was cloudy, the same circumstances, to save energy. Metal electrode discharge is not uniform, commonly known as EDM, in order to achieve material throughout can handle, you need to consume large power.
2)ceramic electrodes and long service life under normal use, no aging. Short life of the metal electrode surface is easy to aging, deformation.
3)Ceramic electrode, high voltage wiring within the electrode core, while the metal electrode pressure directly to the metal electrode, ceramic electrode of the equipment, personal safety factor is much greater than the metal electrode.
4)Ceramic electrode and the metal electrodes require regular cleaning, but just need the surface of the ceramic electrode dirt, dust, wipe the can, the metal electrode to remove surface oxides, the relative trouble.
5)Ceramic electrode price is expensive, and usually come from imports, more than 10 times the price of the metal electrode.
6) Ceramic electrode with a metal roller or ceramic roller, ceramic roller is the best, but the price is very expensive, the average user, with metal roller; metal electrodes with metal roller can be equipped with ceramic rollers and silicone roller (including package rubber roller), ceramic roller is expensive, so the general domestic manufacturers are equipped to package the rubber roller, because they are inexpensive, but the silicone in the case of long-term discharge and ozone erosion will gradually aging, the use of a period of time, you will find some residue points stained in the processing of the material on the back of this package Cots fall rate of qualified products will be greatly reduced.
2.Coated with corona
The principle of the corona by high-frequency high-voltage discharge, air ionization, resulting in low temperature plasma, air plasma on the surface bombardment, resulting in a more complex physical and chemical reaction, improve the surface adhesion (jargon called surface tension , or up by value) to solve the composite open plastic, printing, Lu Bai, deinking and other issues. Many laminating manufacturers to improve the coating quality, used in laminating laminating film, so the cost will be greatly increased, if the traditional ordinary film, will be prone to unglued, open the plastic phenomenon. Ordinary film to go through the corona treatment, adhesive coated, it will greatly improve the quality of the coated. Thus avoid unglued, open the plastic to bring you the loss of. Even if you buy the film manufacturers have corona treatment, the treated film surface tension is not stable over time, the role of light, temperature, air infiltration, the processed film in 5 - 30 days, gradually weakened, restored to the original value. Therefore, when conducting film coated the general-line corona treatment is appropriate, the front of the appliance corona, intermediate coating, the back-end coated.
3.Label printing, digital printing and corona
The principle of the corona by high-frequency high-voltage discharge, air ionization, resulting in low temperature plasma, air plasma on the surface bombardment, resulting in a more complex physical and chemical reaction, improve the treated material (such as BOPP) surface adhesion (Professional term called surface tension or dyne value), to solve the problem of the composite open plastic, printing, Lu Bai, deinking. Label printing, the first pass through the corona treatment, and then printing, label printing quality will be greatly enhanced. So as to avoid the loss of printing Lu Bai, deinking bring you. Even if you buy the film manufacturers have corona treatment, the treated film surface tension is not stable over time, the role of light, temperature, air infiltration, the processed film in 4 - 30 days, gradually weakened, restored to the original value. Therefore, we recommend to generally use during label printing line corona treatment is appropriate, the front of the appliance corona, back-end printing. In addition, currently on the market a growing number of digital printing, but also has the same reasoning.
4.Lights waterproof seals bonded pre-treatment
Automotive headlamp base PP, PC, ABS, and other materials, internal immersed lights in order to prevent the moisture in the air or rain, the headlights of the waterproofing treatment is very important. The usual method is to use waterproof rubber seals, aggregate spray low temperature ion plasma length of approximately 20mm in depth which the lights of the trench, the surface of the base material after treatment to 65dynes/cm above can be very good with The ring bond, without the need for primer. Use of low temperature plasma processing lights have gradually become an important part of the lights on the water treatment process.
5.Plasma processor and automotive manufacturing
Measure an important indicator of the quality of the car is the tightness. Sealing tape has a very important role in the car, it has to fill the gap between the body parts and damping role, not only to prevent outside dust, moisture, water and smoke intrusion, but also blocking noise intrusion or leakage . Sealing tape to install parts of the classification, the main doorframe seal around the windshield seal, side seal, sunroof seal, engine hatch seals, trunk seal, including contact with the owners of the most doorframe seal, on the bus and get off are likely to come into contact with it. The sealing strip in accordance with the different structures, useful single rubber made by the combination of rubber and foam sponge rubber constitute. The rubber material used to seal the tape three of dense rubber, sponge rubber and hard rubber. Hard rubber is quite hard .Seal rubber mostly used anti-aging resistance, low temperature, water gas, chemical resistant, especially resistance to ozone aging of ethylene propylene diene monomer (EPDM), EPDM also has a good workability, and strip , wire braid, velvet, flocking, PU coated, silicone coating compound to ensure the cars with the outside world, waterproof, dust, noise, heat insulation, damping, and decorative role, under normal circumstances EPDM seal life up to 10 years.. The sealing strip is squeezed out forming method processing, the production methods of the past is relatively simple, can be processed by a simple mold. With the increasingly high demand for vehicle sealing, the requirements of the sealing strip. New techniques, new materials are emerging processing technology will become increasingly complex. For example, in recent years, with the thermoplastic elastomer technology continues to evolve and mature, a new type of thermoplastic elastomer material such as TPO and TPV automotive sealing applications are becoming increasingly common. These materials not only has the excellent performance of the elastomer, but also has the excellent characteristics of the plastic, both for the convenience of processing, but also recyclable reuse these materials is gradually replacing the EPDM products. Common door seals by the co-extruded solid core carrier with sponge rubber hose to seal the composition of the sponge in part by the compression of the body door frame to provide the sealing function. But when the speed is high, the external air pressure may be more than a cavernous provide maximum sealing force, causing seal failure. To solve this problem, some companies have designed a new type of seal profiles, magnetic rubber into the corpus cavernosum, in the corpus cavernosum on the magnetic layer coating or by adding the magnetic slug occurrence of magnetic body metal frame , thereby increasing the sealing function of the corpus cavernosum. Automotive sealing the surface tension of the rubber material is very low, velvet, flocking, PU coating, silicone coating process, the material of the coating process difficult attachment, usually manually segmented grinding process to increase the strip surface roughness, and painted the end of plastic grinding process time-consuming, low capacity, can not cope with the extrusion equipment online processing likely to cause secondary pollution, the high cost of qualified low, many problems. Even so, with the increasing requirements, the grinding process has been unable to reach the department standard and European standard automobile manufacturing the product. Using our plasma processor on a variety of automotive sealing surface treatment, after the determination of surface to achieve> 60dynes/cm2, polished or coated with polyester can remove processes, without primer, and according to the extrusion or flocking machine speed to do online processing, increase productivity, reduce costs, no damage to the tape surface, and to meet the environmental requirements of the coated water-soluble glue. The low temperature plasma has been used in the car doorframe seal, door head and said, window guides, window side bars, front and rear windshield and front and rear cover seal, and so the handling of the product.
6. Folder gluer with ion processor
Automatic folder gluer is widely used in packaging industry, played a large role in the production of all kinds of packaging. With the continuous expansion of consumer demand, consumer quality, continuously improve, automatic folder gluer to run faster and faster, there is a growing need that beautiful box, including laminating, UV coating and so on, these new types of packaging boxes have a common characteristic, that is sticky is not strong, easy to open plastic. Start, device manufacturers first thought was to install a grinding machine, automatic folder gluer, the mechanical friction between the wheel and the box bonding at roughening the bond, thus more than some plastic to reach the stick The purpose of prison. Grinding wheel and the shortcomings are obvious, and destroyed the surface of the box. The grinding wheel will produce a large number of scraps of paper droplets, production workers passively confetti droplets inhaled into the lungs, long-term work will get lung cancer. Three scraps of paper filled with grinding wheel face, reducing the friction between the wheel and the box, thus affecting the quality of production (at the beginning can cement behind will stick is not strong). With the birth of the plasma processor, an electronic polished instead of the grinding wheel. Start, device manufacturers first thought was to install a grinding machine, automatic folder gluer, the mechanical friction between the wheel and the box bonding at roughening the bond, thus more than some plastic to reach the stick The purpose of prison.
Grinding wheel and the shortcomings are obvious, and destroyed the surface of the box. The grinding wheel will produce a large number of scraps of paper droplets, production workers passively confetti droplets inhaled into the lungs, long-term work will get lung cancer. Three scraps of paper filled with grinding wheel face, reducing the friction between the wheel and the box, thus affecting the quality of production (at the beginning can cement behind will stick is not strong). With the birth of the plasma processor, an electronic polished instead of the grinding wheel. The plasma processor, which some customers call e-grinding machine, air plasma bombardment box needs bonding at the surface, resulting in a more complex physical and chemical reaction, thus greatly improving the surface adhesion (jargon known as surface tension or dyne value), to ensure the paste box stick was labor, not a plastic.
Plasma treatment, surface treatment on the box depth is small, but very uniform. Second, no scraps of paper droplets appear, are environmentally friendly processing. Third, a certain distance between the ion nozzle from the box, but the low-temperature plasma jet through the nozzle to the Office of the box gluing, very good continuity of production, regardless of the length of time, product quality is consistent.
Our plasma processor, emitted from the low-temperature plasma, shaped like a flame, but will not ignite the box. In addition, user-friendly, our plasma processor also has a safety interlock feature, users may need to stop signal (passive normally open contacts) in series to the device, folder gluer, once the shutdown of plasma processing The opportunity instantly and automatically stop the jet plasma folder gluer boot, it automatically emitting plasma.
Our plasma machine, there is a remote control function (based on user needs), remote alarm function (based on users' needs can lead to passive normally open contact, normally closed node), the parameter memory.
