Easy-to-detect plastic parts: Food processing
Foreign materials have no place in food, and yet undesired contamination makes its way into production processes time and time again. JW Winco has established a new line of standard parts made of plastic that are easy to detect -- visually and with metallic sensors -- even in pasty and opaque media. The visually detectable (VD) knobs, cabinet U-handles, hinges, hand levers, and three-lobe knobs are made of solid-colored blue plastic. The metal detectable (MD) standard parts are also made of blue plastic but contain additional additives with iron oxide. These parts can be used in both the food and pharmaceutical industries without reservation. Learn more.

New paint makes tough self-cleaning surfaces
By Hayley Dunning, Imperial College London
A new paint coating that makes robust self-cleaning surfaces has been developed by an international team of researchers.
The coating can be applied to clothes, paper, glass, and steel. When combined with adhesives, it maintains its self-cleaning properties after being wiped, scratched with a knife, and scuffed with sandpaper.
The study involved researchers from University College London (UCL), Imperial College London, and Dalian University of Technology (China), and it was published the first week of March in Science. It shows how the new paint, made from coated titanium dioxide nanoparticles, can give a wide range of materials self-cleaning properties, even during and after immersion in oil and following damage to the surface.
Self-cleaning surfaces work by being extremely repellent to water but often stop working when they are damaged or exposed to oil. The new paint creates a more resilient surface that is resistant to everyday wear and tear, so it could be used for a wide range of real-world applications from clothing to cars, say the researchers.
Co-author Dr Colin Crick, from the Department of Chemistry at Imperial, said: "The surface coating we developed is not only formed with relative ease, but can also be applied to a wide range of materials. The production of robust self-cleaning surfaces is a key step in ensuring that these highly promising materials can be widely used."
Extremely water-repellent surfaces cause water to ball into tight droplets. When these roll about on the surface, they pick up dirt, viruses, and bacteria, cleaning it without any scrubbing. In this way, a rain shower could clean a car instead of making it dirty.
Different coating methods were used to create the water-repellent surfaces, depending on the material. An artist's spray-gun was used to coat glass and steel, dip-coating for cotton wool, and a syringe to apply the paint onto paper.
All the materials became waterproof and self-cleaning as water droplets of different sizes were seen bouncing instead of wetting the surface, removing the dirt applied by the researchers. This was maintained after damage was inflicted on the surfaces.
First author Yao Lu from UCL, said: "Our paint worked extremely well for a variety of surfaces in tough conditions that were designed to simulate the wear and tear of materials in the real world. For example, car paint frequently gets scuffed and scratched, and we wanted to make sure our paint would survive that."
The experiments were filmed to show the behavior of the treated surfaces against controls. Examples include videos of treated cotton-wool being dipped into blue-colored water and emerging pristine white with no trace of contamination, and treated paper remaining dry and clean after being exposed to dirt and water.
Co-author Professor Claire Carmalt at UCL said: "The biggest challenge for the widespread application of self-cleaning surfaces is finding a way to make them tough enough to withstand everyday damage. The surfaces tend to be mechanically weak and so rub off easily, but by pairing our paint with different adhesives, we've shown it is possible to make a robust self-cleaning surface. We used materials that are readily available, so our methods can be scaled-up for industrial applications."
