Meech proves a sparkling success with Viracon
Thursday 07. May 2009 - The clarity and quality of glass in some of the worlds most famous modern buildings is being assured thanks to static elimination technology from Meech International.
Viracon, which offers the worlds most complete range of high-performance architectural glass products, has installed intelligent technology from Meechs 900-Series static elimination range on production lines at its site in Statesboro, Georgia, USA, to effectively combat the high levels of static commonly encountered during glass production.
The manufacturing process involves extreme shifts in temperature that create a high static charge, causing airborne debris to be attracted to the glass surface. Once the glass has been contaminated by these fine particles, the application of laminate layers and other substrates between sheets can prove difficult and the clarity of the glass can potentially be compromised. The situation is exacerbated by the plastic or rubber rollers on which the conveyor belts run.
Viracon has supplied glass for some of the most impressive and famous buildings worldwide, including the worlds tallest building, the Taipei 101 Tower and the brand new Chicago Trump Tower. With high profile installations such as these, the company is naturally committed to delivering a product of the highest quality and aesthetic appeal.
Lee Quick, process engineer at Viracon, comments, “Our aim in installing static elimination equipment was twofold; firstly it was important to decrease the levels of waste created due to static attraction in the laminate layer and secondly, Viracon wanted to ensure the safety of employees by eliminating the risk of large static shocks.” Static levels in glass often exceed 125KV. This can result in painful and potentially dangerous discharges.
In the search for a reliable and cost-effective method for maintaining premium quality, Viracon was impressed by Meechs status as industry experts and, having purchased Meech Air Technology equipment previously, knew that the company had a comprehensive understanding of its application requirements. “After extensive research we found that Meech was able to supply the hand held static meters needed to accurately measure static electricity readings of up to 200KV, a common level in glass production,” says Lee Quick. “We were very impressed by the companys consultative approach. Not only did the Meech team demonstrate extensive knowledge of static elimination in all areas, but they made the working relationship comfortable and enjoyable.”
Viracon purchased Meech Pulsed DC Feedback systems that are installed at strategic points above and below the production line. The major advantage of this system is that as each pane of glass moves along the conveyor belt a sensor adjusts the output levels of the ionising bars automatically. In addition the Pulsed DC solution does not involve airflow so there is no risk of contaminants being blown towards the glass. The installation has been so successful that static levels have dropped by as much as 96% to a minimal 2KV – 5KV.
Viracon is delighted by the effect of installing Meechs static eliminators. Lee Quick comments, “Waste levels have been significantly reduced and the laminate interlayer is much easier to apply as the contaminant rate is minimal. We are thrilled with the set up now in place and the money it has saved enables us to deliver the performance solutions we promise our clients on budget, as well as guaranteeing the high quality aesthetics associated with our product.”
