Corona Treatment of Polypropylene Sheets for ARM Buildings

ARM Buildings Limited, one of the largest suppliers of pig buildings within the UK, have been operating within the industry for thirty-five years. Their long history of product development has undoubtedly helped to cement their outstanding reputation for being a high quality service provider for both the engineering and building industries.

ARM Buildings contacted Dyne Technology when seeking a solution to gaining strong adhesion to the internal polypropylene panel cladding used to build the high quality pig buildings.

With over 40 years industry experience, UK based Dyne Technology were confident that by working closely with the ARM Buildings team, a solution could be found that would both solve the problems of adhesion and optimise their manufacturing process. Working together with the engineers at Lichfield based Dyne Technology, the ARM Buildings team has implemented a solution to improve the adhesion of the low surface energy polypropylene internal cladding.

“Dyne Technology is the perfect partner for us, they offer excellent UK based support, have a very flexible approach and they were both technically and commercially competitive”. – Andrew Brittain, Operations Director – ARM Buildings

Corona Treating PolypropyleneThe most appropriate Surface Treatment Technology was proven to be the Foam and Board Corona Treating unit, used to modify the surface of the polypropylene internal face panel. Corona Treating significantly increases the polypropylene’s polarity, which significantly contributes to the level of adhesion that can be achieved, prior to bonding onto the stud frame and insulation.

Corona Treatment of Polypropylene sheets

The Dyne Technology team worked closely with the engineers at ARM Buildings to ensure the specification of the Corona Treating unit met their exact requirements. Single and dual sided treatment systems are available with a treatment width of up to 3 metres wide and a board thickness of up to 50mm. In this instance only a single side of the polypropylene panel needed to undergo surface activation which brought ARM Buildings considerable cost savings.Foam and Board Corona Treating

The board and foam Corona Treating unit is mounted on wheels to allow easy relocation within the production facility, giving flexibility to ARM Buildings’ manufacturing process. The unit is equipped with an automatic sliding door which enables easy access to the treating area for cleaning or maintenance.

The unit is also equipped with safety switches and interlocks to ensure safe use, while an ozone extraction and filter system is supplied which eliminates ozone generated during the treatment process ensuring safe use. After delivery, Dyne Technology’s UK based experts installed and commissioned the unit before conducting on-site training for the ARM Buildings production teams.

Corona Treatment of Glass Sheets Prior to Coating Application

A stand-alone Corona Treatment unit is the surface activation method of choice for a major European glass producer when seeking improved bond strength to glass sheets prior to a coating application.

The glass sheets undergoing treatment vary in size from 50mm to 1000m, as a result of this, the customer sought a flexible solution to ensure consistent treatment levels despite the parts varying in size.  Alongside this, a key customer demand was for a treatment system that did not damage the surface of the glass sheets during production.

Repeatable Surface Activation

Corona Treatment Coating ApplicationTo meet these key requirements, the stand- alone Corona Treatment unit is well equipped to ensure consistent treatment of the varying size glass panels which can be processed at a range of treatment speeds from 500mm per minute to 3000mm per minute.  The solution provided utilises a single high frequency wire electrode which is accurately positioned 2mm off the surface to be treated; this accurate positioning ensures no damage to the material’s surface while achieving optimal, consistent treatment levels.

Corona Treating Glass SheetsThe low maintenance, high performance treatment system is available for both single and double sided treatment, providing flexibility to fit your manufacturing process while ensuring optimal treatment levels.

To facilitate ease of installation at the customer site the standalone Corona Treatment unit was bench mounted to also ensure easy integration into the existing manufacturing process.

Corona Treatment Improves Print Adhesion for STERIS Healthcare

Industry:

medical-plastics

Plasma Treating Steris Healthcare

Albert Browne, part of the STERIS Healthcare Corporation who provide sterile processing equipment to the medical industry contacted Dyne Technology when looking to improve the adhesion quality of their printing ink on the sterile indicators that are widely used in hospitals throughout the UK & Ireland.

The sterile indicators are vital to the Sterility Assurance Program, their Process Control Products are in-process control check points to prevent the mix-up of processed and un-processed packs (container, pouch or wrapped tray) and enhance patient and personnel safety.

Repeatable and reliable Narrow Web Corona Treatment

The Dyne Technology engineers conducted an initial on-site assessment to better understand the problem faced by Albert Browne. The sterile indicator tabs underwent a series of tests and it became clear that the surface of the plastic material would achieve a stronger level of adhesion with Plasma Surface Activation. Plasma Surface Activation would allow the printing ink to fully wet the surface and achieve the high level of adhesion required.

Web TreaterWhen choosing Surface Activation method, it was critical for the Dyne Technology engineers to work closely with Albert Browne to ensure most efficient treatment method is selected. From this, High Frequency Corona Treating equipment was chosen as the most effective treatment method for both the part requiring treatment and the manufacturing process utilised. High Frequency Corona Treating equipment was successfully installed by Dyne Technology engineers on the current printing line for surface modification at their manufacturing facilities.

Inside a web treaterThe high frequency narrow web Corona Treating equipment system supplied by Dyne Technology is designed for the pre-treatment of conductive and non-conductive narrow webs and can treat either one or both sides of the web as well as accommodating production speeds of up to 150m per minute.  The compact design and construction enables the equipment to be mounted directly onto the treating station which completely removes the need for trailing high voltage cables.  Running from standard 230Volt, 13Amp socket outlets the corona treating equipment easily fits to new or existing production lines and presses.

 “Dyne Technology has worked very closely with us to provide a cost effective and robust solution. The treatment system installed has improved the print adhesion enormously and therefore the overall quality, reliability and performance of our Process Control Products.” – Jonathan Coleman, Deputy Manufacturing Manager at Albert Browne

Corona Treatment explained…

Question ButtonCorona Surface Activation is achieved by creating a high voltage, high frequency electrical discharge, known as Corona discharge in close proximity to the parts to be treated.  This high energy corona discharge is attracted to the material and modifies the molecular bonds on the surface. These modified bonds are now free to attach to free radicals and other particles that exist in the highly active corona discharge environment. The resulting formation of additional polar groups on the material surface have a strong chemical attraction to inks, paints, coatings, adhesives etc, the increase in surface energy significantly contributes to the bond strength that can be achieved.
