Infrared Emitters Allow Heating Processes to be Automated

Application Specialists at the Hannover Fair

Corrosion protection on large metal components, clear varnish on plastic products, coloured décor on stone – different coatings need to be dried on a large number of different products.

Infrared systems help to ensure that the heating steps required for drying are carried out as efficiently as possible.

In the “Surface Technology in Practice” area of the Hannover Fair, which takes place from 4th to 8th April, Heraeus Noblelight will be presenting its infrared emitters on Stand J34 in Hall 6, where visitors will also have the opportunity to meet with application specialists.

Small, irregularly shaped stones or other bulk materials are dried just as reliably as large surface metal parts using infrared heating technology. In both cases it is vital that the heating source is exactly matched to the product and the process. It is often worthwhile to put the complete system on the test bench to increase output and minimise energy consumption.

Metal plates must be heated homogenously over the complete surface to guarantee the quality of the coating. A precisely matched emitter arrangement in combination with a suitable control system brings significant improvements.

Using a suitable guidance system into the system, which ensures the optimum alignment of stones or granules to the radiation, bulk materials can be dried significantly more efficiently.

Drying of Coatings

No coating process is exactly the same as another but with all processes it is important that the lacquers and paints should be dried to high quality and as quickly as possible.

Many coatings set challenges which cannot be met with standard heat sources. The coating system defines the data framework. Water evaporates more slowly than solvents, so that infrared emitters dry water-based lacquers significantly faster because they are optimally matched to the absorption properties of water. Nano coatings to some extent require very high temperatures, which can be reliably delivered by infrared emitters. Powder coatings must be gelled very quickly and it saves time and money if only coating and surface are heated. The products are then ready for further processing much more quickly after the heating stage.

Optimising the System Saves Energy

The drying of lacquers and coatings increasingly needs to be faster but at the same time, drying must produce a top quality product and use the minimum amount of energy. The reduction of energy and material costs is very important to industrial companies in their struggle to maintain or improve competitiveness. Often it is more sensible and cost-effective to optimise an existing system rather than introduce new plant. A newly formed consulting team at Heraeus Noblelight offers support here through individual consultancy, practical planning and the prompt implementation of measures to optimise systems and processes.

Energy Efficiency Through Precise Matching

Infrared heating technology offers several possibilities of optimising energy consumption in industrial heating processes:

• High heat transfer capacity
• Contact-free heat transfer
• High efficiency
• Efficient energy transfer through the use of optimum wavelengths
• Energy usage confined to the working area by matching to the product shape
• Energy used only when required because of fast response times
Infrared heat will always be used whenever heating processes with particular challenges in terms of space, time or quality need to be resolved. Infrared emitters can be precisely matched to product and process and this saves energy and costs.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
