Carbon Infrared Emitters Improve Quality

25.07.2011
Infrared heat helps to heat plastics homogenously

Foils for foodstuffs or heavy duty floor coverings – modern plastic materials need heat during processing. Coatings or adhesives are dried and plastic foils are pre-treated by heat before embossing or lamination. Carbon infrared emitters from Heraeus Noblelight are helping Polyflor from Manchester in the embossing of heavy duty floor coverings and improving quality.

Infrared systems heat large, flat materials rapidly and homogenously, directly before the press or the embossing station. This saves both energy and cost. Heraeus is presenting infrared emitters for plastics treatment on stand 1121 in Hall B1 at the Fakuma exhibition, which takes place in Friedrichshafen from 18th to 22nd October.

Multi-layer plastic foils are used for the hygienic packaging of foodstuffs. To join the layers together, the foils are heated and then joined by means of calenders.

Heavy duty plastic floor products often have a decorative embossing. To achieve a high quality result, after a pre-heating, the surface is then directly heated again shortly before the embossing station. Whether laminating or embossing, the large surface must always be heated homogenously and, hence, it is important that the correct heat source is selected.

Carbon infrared emitters improve the quality of floor coverings
Polyflor, of England, manufactures heavy duty floor coverings for use in schools, hospitals and commercial organizations, throughout the world. In the manufacture of floor coverings in Manchester, a 2m wide PVC (polyvinyl chloride) web is heated by infrared emitters before being embossed with decorative patterns. Short wave infrared emitters had previously been used for this application but they did not heat all colors optimally and geometric integrity was often affected during embossing.

In order to solve the problem, intensive tests were carried out in the Heraeus Application Centre, and as a result, a medium wave carbon infrared system was installed. Short wave infrared radiation penetrates deeply into thick plastic materials, while medium wave carbon infrared emitters can heat the surface better. Tests can demonstrate which radiation is best for specific tasks.

Neil Holden of Polyflor is convinced of the benefits of the infrared system, “The new system has ensured that embossing no longer affects floor covering geometry. We were very impressed with the tests carried out at the Heraeus Application Centre and with the way that the system was installed with minimum interruption to the production process.”

Process Improvement by Exact Matching

Infrared heating technology offers various possibilities to optimize industrial processes:

• High heat transfer capacity
• Contact-free heat transfer
• High efficiency
• Efficient energy transfer by selecting optimum wavelengths
• Spatially focused application of energy by matching the heating to the product shape

• Fast response times to reduce energy consumption

Consequently, infrared heat is always used when heat processes are to be implemented which require particular targets in terms of space, time or quality.

Im Focus: Optical Nanoscope Allows Imaging of Quantum Dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
