What Causes Static Electricity

Static electricity can be defined in simple terms as the sudden transfer of electricity from one object to another.

Friction
When two surfaces rub together; for example, paper being fed through a photocopier.

Separation
When one surface is removed from the other; for example, removing the protective film from acrylic sheet.

Machine Processing
When a surface undergoes a machine operation such as cutting; for example, computer cutting can agitate a vinyl surface causing it to curl or fold.

Heating
When a surface undergoes heat treatment the temperature of the surface is quickly increased or decreased causing build-up of static charge; for example, mounting a picture onto a foam backed board.

 

The Problems it can Create

Dust attraction
Static charges act rather like a magnet which explains why dust particles are attracted to non-conductive materials such as plastic.

Interference with Production Processes
The presence of static can be problematic for those working with acrylic sheet (such as sign makers) and when mounting photo montages or sealing pvc vinyl graphics.

Shocks to People
Unpleasant "shocks can be felt when handling statically charged materials. A charge may also occur when walking over carpets or getting into a vehicle.

Damage to Electrical Components
Static discharges may also cause component failure in electronic equipment.

Cleaning with a dry cloth tends to aggravate the problem by creating more static charge on the surface. Washing with water alone will initially leave the surface dust free but, without a protective antistatic coating, once the surface is dry the problem of static charge reappears.

 

The Solution

 
Farecla Anti-Static Spray

Antistatic Cleaner is a water based liquid suitable
for use on most surfaces.
Treating the surface with Antistatic Cleaner will delay the
development of static charge for over one month (in normal indoor humidity conditions).

Sign Making

 

Removal of Protective Film
Protective film (or masking) is used to prevent damage to acrylic sheeting
(such as PERSPEX®) during normal handling and transit.

All grades of acrylic sheet have good electrical insulating properties and high surface resistivity, and as such are readily charged during and/or after removal of the protective film.

Treat the acrylic sheet with Farecla's Antistatic Cleaner after the protective film has been removed to clean the surface so eliminating static charge and reducing the attraction of dust for over one month.

Machine Processing
Static build up on acrylic sheetProblems with static charge are also encountered when cutting or
carrying out certain machine operations on acrylic or plastic coated
surfaces where the protective film must be removed prior to machining.
Static discharge builds up as the surface becomes agitated by the
machining process. The plastic "swarf or dust produced is then
attracted to the surface.

Applying Antistatic Cleaner to the surface after machining will clean the surface of plastic
"swarf" , remove static charge and reduce the attraction of dust to the final product.

Cleaning the Final Product
If the sign is to be decorated by spraying or screen printing, use a clean, damp chamois leather to wash the surface down to avoid interference with paint or ink adhesion. Incomplete cleaning and removal of Antistatic Cleaner may affect the adhesion of screen printing inks.

Once the design has adhered to the surface, apply Antistatic Cleaner to the final product to reduce the attraction of dust.

 

Sealing & Mounting

Static charge can also create problems when mounting photo montages or sealing pvc vinyl graphics.

For example, mounting and sealing computer cut vinyl is Applying vinyl graphicsan exacting task.
The cutting process can agitate the vinyl, causing static charge to build up. This increased static level causes the vinyl to curl, making it very difficult to lay the vinyl shape on a surface such as pvc foam sheeting.

Applying Antistatic Cleaner to the vinyl after the cutting process will help to reduce surface resistivity and make it easier to mount the shapes evenly on to the surface prior to sealing.

Passing the surfaces through rollers may also create a static charge and cause the display to move as it is being sealed.

Treating the surface with Antistatic Cleaner before the graphics are laid will help to reduce the surface resistivity and protect against the attraction of dust particles which can become trapped between the two surfaces and spoil the final result.

 

Display Applications

When objects or surfaces form part of a display, dust attraction is a major cause for concern. Static discharge is increased by low relative humidity (dry air conditions) induced by bright lighting, an environment required for eye-catching presentations.

Here are just some of those who can benefit from using Antistatic Cleaner:Display Applications

Exhibition Contractors
Shop Fitters
Photographic and Film Studios
Places of Interest;
      Museums
      Stately Homes
      Art Galleries


Treating the surface to be displayed with Antistatic Cleaner will clean and help to protect showcases, display cabinets, photographic subjects and exhibition stands from dust attraction for over one month.

Reproduction

 

Other uses??????The process of making printing plates (or screens) from film requires a dust free environment to avoid imperfections in the final printed item.

Applying Antistatic Cleaner to the glass surface before contact with the film will remove any dust particles and help protect from future dust attraction, which could create imperfections in the ,printing plate or screen.

 

Other Applications

Antistatic Cleaner is also suitable for use on TV and VDU screens.

Antistatic Cleaner is not suitable for regular use on surfaces in contact with food, or on electrical components.

It is advisable to pre test Anti-Static cleaner on a small test area first.
