Q: How do you prevent workers from getting static electricity shocks?

Problem A very common problem is when people get static shocks from working close to objects that carry a high electrostatic charge. Problems occur when machine operators come close to highly charged materials eg. film on a roll at a winding or unwinding section. A direct spark can jump from the object to the person which is unpleasant and sometimes dangerous. The person can also become charged by standing close to the charged object. A spark will occur only when the person comes near to a grounded metal surface. Solution How can you stop static shocks? In both cases, the solution is not related to the person. The solution is to prevent a high static charge building upon the object. Static charges should be reduced by fitting anti-static devices at the last stage off the process, where the person gets a shock or becomes charged. In most cases, this will solve the problem. Occasionally the charge generation is so high that the object needs to be discharged at other points throughout the production process. The anti-static equipment in the last stage will then reduce the remaining charge to a safe level.

Q: How do you prevent static buildup disrupting the machining process?

Problem The build-up of static charges on non-conductive objects can create enormous adhesion forces. These forces cause materials to stick together or repel each other at locations in a production process creating disruptions. Examples of adhesion: & #8226The plastic film sticks to the idle roller causing disruption in the web tension and web guidance. & #8226Small punched parts stick together & #8226Sheets on a stack stick causing feeding of multiple sheets & #8226Plastic film wound on a roll sticks to the roll when trying to unwind & #8226Bags do not open because the layers are stuck together Examples of repelling: & #8226Yarns for textile travel alongside at very small spacing. Repelling causes irregular spacing & #8226Small injection moulded parts jump out of the box & #8226Sheets float on a stack & #8226Film on a roll during winding is telescoping Solution Placing anti-static devices at strategic positions in the process will help to reduce the static charge and eliminate the problem. Depending on the process various anti-static devices are available for flat surfaces, 3D objects, low speed and high speed and with additional air support if required.

Q: How to prevent static electricity damaging material

Problem Static charge on a material can build up along the process. Friction between idle rollers and film create a charge. Each new friction accumulates charge. Charges can rapidly become very high. Charges over 100 kV are not uncommon. When a static charge exceeds a certain level, spontaneous discharges and sparks can occur causing damage to the material or electronic equipment in the vicinity. Solution Work backwards in the process from the point where sparks have occurred. Place anti-static ionising bars prior to the idle roller. In most cases, static charges are too high to be eliminated by one stage of anti-static bars. Additional anti-static bars are needed to control the static charge from the beginning to the end of the process.

Q: How to remove static charge from material

Problem Static charge in a material can cause problems when this material is used in its next production phase e.g. tubular film used to make bags or a film on a roll which has to be unwound. Due to static charges on the film, the layers will cling together, this will cause issues when trying to separate the layers of material. Solution Start the neutralisation as early as possible in your process, when the layers are still separate because when a static charge is in between two layers it is almost impossible to neutralise. Throughout the whole production process, anti-static equipment should be fitted to keep static levels as low as possible, so preventing a static charge build-up between the layers.

Q: How to prevent static electricity causing fires

Problem Static charge on a material can build up along the process. Friction between idle rollers and film create a charge. Each new friction accumulates charge, charges can rapidly increase becoming very high. Charges over 100 kV are not uncommon. When a static charge exceeds a certain level, spontaneous discharges and sparks can occur. This may lead to ignition of the fumes, and most likely a fire. Solution In explosion hazardous zones it is very important to keep the static level below 3000 V to prevent spontaneous sparks. Anti-static bars should be placed at various stages in the process to keep the level below 3000 V.

Q: How to prevent static attracting dust

Problem Static charge on a material can build up along the process, friction between idle rollers and film creates a charge. Each new friction accumulates charge, these charges can rapidly increase becoming very high. Charges over 100 kV are not uncommon.

Question 11

How to use CleanION systems to remove static and clean particles

Accepted Answer

Problem

CleanION web cleaning systems have been designed to neutralise static charges and, at the same time, to remove particles, even at higher velocities! Each CleanION system is designed to meet specific production requirements. A variety of vacuum hood configurations and dust collectors are available to ensure maximum cleaning and static neutralisation for each application. For all web widths, there are vacuum hoods for non-contact cleaning or contact (brush) cleaning. Vacuum hood configurations are adapted to their individual need. Three basic principles are used: & #8226High vacuum /low volume full contact cleaning & #8226Medium vacuum/medium volume contact cleaning with air assist & #8226High vacuum/high volume non-contact cleaning with balanced air assist Solution A vacuum hood is constructed with a specially shaped suction slot. Prior to the suction slot, the substrate will be neutralised by an anti-static ionising bar. This removes the adhesion force caused by static electricity and creates an ideal basis for the cleaning. Contact systems use a soft brush to loosen particles from the substrate prior to cleaning. Contact cleaning with air assist and non-contact cleaning systems use an MEB Air Knife to blow against the movement of the substrate to force particles into the suction slot. Non-contact cleaners use a closed-loop blower system for the vacuum and blowing air. The web is guided through the double-sided cleaning heads that provide excellent web guidance. Dust collectors are available for each specific system ensuring maximum cleaning efficiency. All dust collectors are equipped with durable three-phase 400V motors. This process can also be used for sheet cleaning. Please contact eStat Solutions for detailed advice tailored to your specific situation. CleanION cleaning systems are very versatile and can be used for many applications and processes.

Question 12

How to use static to clean the surface of a 3D object

Accepted Answer

Problem

Cleaning of a 3D object can be performed efficiently by using ionised air. Ionised air can be produced by ionising air nozzles, air guns or an air knife using compressed air. For large installations e.g. car parts or a complete car, bodies are it more economical to use blower driven blow-off systems. Depending on the application, manual cleaning with a handgun or automated cleaning can be used. This process can also be used for sheet cleaning. Solution Typhoon blower drove ionising air knife system, please contact for detailed advice tailored to your specific situation.

Question 13

How to use static electricity to detect perforations and count bags

Accepted Answer

Problem

High voltage arcing can be used in a controlled way. A spark from a special electrode to a ground reference can be detected and evaluated. Perforations in plastic webs can be detected and counted. A Perfomaster provides the hardware and software to generate a controlled spark over, detect this and evaluate the spark to produce a pulse signal. The pulse signal is available on the output connector and can be used for counting the detected spark and thus perforations. Solution Counting perforations with a Perfomaster to determine the quantity of bags to go on a roll.

Question 14

How to use static electricity to detect perforations in a moving web

Accepted Answer

Problem

Perforations in a web.Solution Perforations in moving webs can be detected with a special detection bar and a high voltage generator. Perforations will be detected but not localised. A special HD-R or HD-C charging bar is mounted over a roller to create a strong electrical field. A perforation in the film will create a spark through the material and will generate an output signal on the charging generator. Due to the strong electrical field, placement of anti-static ionising bars after the perforation detection is mandatory.

Question 15

How to use static electricity to detect perforations in products

Accepted Answer

Problem

Perforations in products can be detected using high voltage to create a spark through the perforation. A common application is testing the injection point of injection moulded products e.g. yoghurt pots, bottles and containers. Solution A special electrode can be placed under the product. Inside the product, a ground electrode is placed opposite to the injection point. Even very small perforations can be detected that cannot be detected by vacuum or pressure systems.

Question 16

How to use static electricity to detect perforations and determine the position of a material

Accepted Answer

Problem

Perforations in a web material can be used to determine the position of the material in the machine. The perforation can be the 'tear-off perforations' of bags or a deliberate perforation made to determine a position. Perforation detection with the use of high voltage is not dependant on the material surface and can also be used with transparent materials. When a perforation passes between the high voltage electrode and a ground electrode, a spark is generated. This spark will be detected and a pulse signal will be available for use by the machine control system. Solution Detect the perforations with a Perfomaster
