How Could Vacuum Plasma Treatment Benefit You ?Vacuum Plasma provides innovative surface modification technology and offers effective solutions to adhesion and wetting problems in many industries. Component preparation using plasma treatment is an important step prior to printing, bonding, painting, varnishing and coating processes.Plasma surface modification provides an economical solution for the cleaning and activation of part surfaces before further processing.
How Does Vacuum Plasma Treatment Help To Solve The Problems Of Adhesion ?To obtain good adhesion to low surface energy materials i.e. low or non-polar materials like PP, PE, HDPE etc. we need to modify the surface i.e. increase its polarity. Placing your components in the highly active environment that exists inside a plasma chamber is the ideal method to increase the material's polarity. The free radicals and other particles that exist in the highly active plasma discharge can attach to the material surface resulting in the formation of additional polar groups on the material surface, these have a strong chemical attraction to inks, paint, coatings, adhesives etc. leading to significantly enhanced surface energy and therefore adhesion.
Atmospheric pressure plasma system readily solve surface adhesion problems for a wide variety of products and applications :
Water treatment, non-slip handle, antistatic treatment, coating, anti-bacterial deodorant processing, printing and processing, with a variety of non-woven textile composite acupuncture treatment, as well as non-woven fabrics with a variety of materials (plastic, film, textiles, etc.) bonding, etc.
The effect of the plasma changes by varying the process parameters such as pressure, power, process time, gas flow and composition. Several effects can therefore be achieved in a single process step.
The generation and accumulation of unwanted electrostatic charges, both surface and airborne, poses a serious problem in various industries and laboratories. For instance, static charges can create havoc with sensitive equipment and electronic components.
This Bench Top instrument is designed to neutralize your ESD work-station or ESD protected area with a stream of ionized air. It does what Wrist straps and Conductive mats cannot do - i.e. remove static charges from nonconductive objects and surfaces.
It is able to rapidly neutralise potentially dangerous charges in a localised area. An axial fan gives the desired air flow to neutralise static on specific objects rapidly, as well as control static in the general area in front of the ionizer.
This is a powerful, trouble free and compact solution to static control problems anywhere. The unique high efficiency ionization pulse circuitry provides fast discharge with minimum air flow. A high air flow would lead to operator discomfort and may also disturb small components.
This static eliminator works on the principle of high voltage corona discharge to produce the neutralising ions. It is designed for continuous use and a current limitor circuit ensures operator safety even if the ion emitters are accidentally touched.
The eltech-312 has special circuitry to ensure a balanced ion output. This ensures that no net charge is induced by the ion shower. Balance is maintained irrespective of supply voltage and even if the discharge electrodes are dirty. Balanced output is essential when used in ESD protected areas.
Eltech sheet corona treater is widely used to treat PP, PVC and metallised polyester laminated sheets to increase surface tension and gives better printing and adhesion. Water-based and UV inks printed on plastic films and other substrates create a need for the substrate to be treated prior to printing.
Conventional method of roll to roll treatment is standard practice, but in Offset, Sheet corona treatment is required to increase surface tension or improve the printability. Some substrates are corona-treated when they are manufactured. Many of these substrates require a surface energy boost to match a particular ink or coating. This is done with corona pretreaters on the press just prior to the coating application point.
PVC, PP, LD, Foam, Flex, metallized polyester, PE, OPP and other high-low density plastic materials should particularly be Corona treated to enhance the quality of the final product.
Corona treater on blown film or cast film extrusion lines is essential in order to obtain a perfect surface tension prior to the following converting process. Without pretreatment the extruded substrates will not allow further converting processes due to low surface tension.
Corona treatment is required on Extrusion coating/Lamination plant For better adhesion of thin layer of polyolefin's (Mainly LDPE / PP) on substrates like Paper, Cotton Cloth, Woven fabrics, Jute fabric, Aluminum foil, BOPP film, Polyester film, etc. Paper, Cotton Cloth, Woven fabrics, Jute fabric, Aluminum foil, BOPP film, Polyester film, etc has to be corona treated before coating to achieve better bonding.
Corona treatment system is a very effective way to increase the surface tension of virtually any material. Surface treatment is required for woven fabrics whose normal surface tension is not sufficiently high to permit good wetting , corona treatment increases bonding. Corona treaters increase the surface energy of films, foils, and paper to improve wettability and adhesion of inks, coatings and adhesives. Film extruders use corona treaters to increase a films surface energy at the time of extrusion. This pretreatment process enables the film to be later converted by printers, coaters & laminators.

Surface tension test pen is a fast tool for testing the wetting tension of materials on the surface. At present, the basic materials found in life, the surface generally needs to know the surface energy value before processing, in order to know whether the next process can be produced. For example, plastic parts, steel, glass, ceramics, etc.
The surface of these materials is inert. Before printing, gluing, bonding, compounding, etc., it is necessary to understand the wetting tension of the plastic surface in order to carry out the necessary pretreatment before ensuring the stability of the new product. For example, plastic film is a kind of non-polar material. If it is used as food packaging, it needs compounding, gluing, aluminum plating, printing and other processes.
Generally, the wet tension of the surface of plastic film is less than 36dy/cm. If it is not detected, it will be directly processed. It is very likely that the finished product will have a phenomenon that the adhesive layer is easy to tear, the aluminum foil is not firmly adsorbed, and the ink is easily peeled off after printing. If the surface wetting tension reaches 36 dy/cm or more after treatment, the situation is greatly improved and the quality is guaranteed.
The development and use of new international materials has never been developed. The combination of metal and plastic, plastic and paper, conductive materials and non-conductive materials will involve the magnitude and balance of surface tension values. The surface tension test pen is an indispensable tool for improving product quality, saving costs, investing less, detecting accurately, and reducing losses.
Method for determining the dyne value :Dyne pen draws a line on the surface of the material. After 23 seconds, observe whether shrinkage occurs and condenses into water droplets. If there is a shrinking water bead, change the Dyne pen of the lower level value and draw a straight line until it does not shrink, and there is no waterdrop point to determine the surface tension value of the object.
LABORATORY TYPE CORONA TREATMENT TO TREAT LABELS FOR TESTING PURPOSE IN LABORATORY
Corona treating is a very effective way to increase the surface tension of virtually any material. When properly applied to your substrate, corona treating produces the higher surface dyne levels needed for good adhesion even on the more difficult-to-treat materials like polypropylene and polyethylene.
Other common corona treating applications include nylon, vinyl, PVC, PET, metallized surfaces, foils, paper, paperboard stock, and other materials. For the treatment of sample film prior to adhesion or printing. The film to be tested is placed on the earthed base plate and is then passed over with the manual roller electrode.
The generator power can be set and is displayed. The intensity can also be regulated by varying the movement speed.
The unit is most suitable for quick and simple tests. The compact design of the unit allows it to be taken to a customer and to perform tests on site.
The device comprises a semi-conductor generator with an integrated transformer for high-voltage generation, the hand roll electrode (standard working width 200mm), the earthed ground plate power cable and a hand or foot-operated switch for the activation of the Corona discharge. The output (intensity of the Corona discharge) can be adjusted at a potentiometer and read off a display.
The purpose of corona treatment is to optimise the adhesion properties on polymer-based materials. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings which by nature present significantly high surface energies. To obtain optimum adhesion, it is crucial that the surface energy of the substrate is equal or higher than the surface energy of the material to be applied to the polymer.
Easy InstallationInstallation and start-up are remarkably easy with a plug and play design. Simply roll the system into place, connect to your exhaust, power up the system and converters are ready to treat.

Ionizing air blower or anti static blowers are the most versatile ionizer to control or remove static electricity. This static control blower offers the ability to cover a large area cost effectively. This static control equipment is an excellent choice to reduce static electricity and reduce operator static shocks and production applications needing large area coverage.
Static eliminators are used to eliminate static and dust. Static electricity is a problem, which companies face globally. It primarily affects industries, which handle non conductive materials like plastics, paper, board, laminates and textiles. The electrostatic attraction repulsion cause materials to stick to machinery, or to each other, leading to jams, slow machine speed and poor quality and productivity. Friction, pressure and separation are the major causes of static electricity. When humidity is lower, higher static charges are generated. It becomes more noticeable in the months of winter, in dry laminates, and in air conditioned environments.
Ionizing Air Blower Model- Eltech 310AThe Model eltech 310-A are designed for static control application applications where high volumes of ionized air are required to cover a large area. Producing 255 CFM, the blower can be used singly or several mounted end on end covering a wider area.
Ionizing Air Blower Model- Eltech 310BThe Model eltech 310-B are designed for static control application applications where high volumes of ionized air are required to cover a large area. Producing 255 CFM, the blower can be used singly or several mounted end on end covering a wider area.
Antistatic air gun or Ionizing gun is the ideal technique of removing static, contaminants and dust from three dimensional parts before assembling, packaging, painting or finishing.The ion air nozzel neutralizes the static electricity and cleans at distances up to 2 feet. When ordinary compressed air is used to remove dust and air nozzel for cleaning purpose, its efficiency gets reduced. In case the static charge, which holds the dust to the product is not neutralized, both the the product and the dust will remain statically charged and capable of re-contamination.
How Ionizing Air Gun Works :Ionizing air gun consists of a trigger and an ionisation head engineered into the finger guard. When the trigger is pulled air travels at high speed from the Static Elimiator Gun, picking up the ionised air produced by the ionisation head. The ionised air is blown at high speed towards the object. The ionisation kills the static electricity, allowing the dust to be blown off. The object will be static-free and unable to re-attract dust.
The instrument produces high voltage, low current in a controlled and safe manner. It's compact size and structure is suitable for most industrial environments. The defect free products and quality ensures efficient use and maximum customer satisfaction.
We have designed the Eltech 331 Static eliminator power supply and the different discharge bars for active discharging of disruptive static charges, which develop during the production processes. The discharge bars and the power supply are used primarily in cases where disruptive static charges on fast moving material webs impair production processes and required to be eliminated.

Ozone (O3) is sometimes called "activated oxygen", basically an allotropic form of oxygen consisting of molecules containing three oxygen atoms. It can be act as a most powerful sterilant to destroy bacteria, viruses and odors if generated in controlled conditions. Ozone generators are machines that convert Oxygen (O2) in to Ozone (O3) by the use of high voltage electricity with the help of ozone generators manufactured by Eltech Engineers at state of art unit.
Ozone can be neither store nor transported because of unstable tendency to breakdown quickly as its a basically molecular detention process that must be carried out with ozone generators. Ozone is very powerful and it has very short life span. When it dispersed in a closed room or vicinity, oxidation process starts and then it perform its job and just disappears. Ozone must be generated at site only. Its life cycle comprises of Generation, Oxidation & Return to oxygen. Ozone can effectively neutralize or kills bacteria, fungus & germs by attracting itself to the contaminants breaking down the cell structure through oxidation and reverting back to oxygen. Ozone is used as a sterilant agent for bleaching, cleaning and oxidizing and has faint chlorine like odor. Ozone is not a stand-alone mold removal tool.
