Solvay develops sustainable Halar ECTFE anti-corrosion coating system

Solvay's new waterborne Halar ECTFE coating system broadens metal corrosion-prevention applications for the chemical processing industry. The coating system is comprised of a high-adhesion primer and topcoat and is easily applied using standard liquid spray equipment. Solvay's Halar ECTFE powder coatings have been used for corrosion prevention for over 40 years for equipment in a range of industries including acids, mining, pulp and paper, pharmaceutical, food and beverage, and semiconductor, among others. The new waterborne Halar ECTFE liquid coating tech expands the range of end-use applications to those that are difficult or impossible to powder coat. This includes complex shapes, uneven surfaces, oversized vessels, pipe interiors, and tanks and containers. Moreover, it provides engineers an alternative protective metal coating option to corrosion-resistant alloys (CRAs).

Lightweight, heavy-duty thermoplastic planks introduced

If you're told to walk the plank these days, you may find yourself walking on plastic. SABIC recently introduced its STADECK heavy-duty panels to the Americas. These high-strength but extremely lightweight panels are used for scaffolding and numerous other applications in the building and construction industries. They are made from glass fiber-reinforced thermoplastic resin and are up to 60 percent lighter than wooden planks, saving not only your back but also the gas or diesel it takes to tote heavier support materials around. They also never rot or corrode.

Plastic torque-limiting wing nuts

JW Winco, a leading supplier of standard industrial machine components, has now made available EN 5320 Plastic Torque Limiting Wing Nuts, which are used when manually applied torque is to be limited. Turn clockwise, and the torque of the wing nut triggers an "over-engagement" when the specified torque is reached. When tightening, this will ensure the maximum permissible torque is not exceeded. Turn counter-clockwise, and the torque needed for loosening will always be transmitted properly. The technopolymer plastic is glass fiber reinforced and temperature resistant up to 176 F (80 C). The wing nuts are available in either a black matte or orange matte finish. An aluminum version (GN 3663) is also available.

Top Tech Tip: Mechanical bellows components are an alternative solution

In today's digital world, mechanical components such as metal bellows serve as an extremely reliable mechanism to gather information. The movement of Servometer® electrodeposited metal bellows under hydraulic or pneumatic pressure (internal and external) can create the information needed for a system w/o electricity. Using bellows technology; temperature, gauge, barometric, and differential pressure can be compensated for. With miniature sizes available, Servometer bellows can be added to instrumentation and manifolds of almost any shape or size.

Researchers find intrinsic 'fingerprints' that could detect tampered steel parts

David Mascarenas, a research and development engineer at Los Alamos National Laboratory, used Barkhausen noise to find unique-looking "fingerprints" in steel that could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.

 

 

 

 

Researchers using magnetic signals have found unique "fingerprints" on steel that could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.

"Magnetic signals provide a wide range of possible national security applications," said David Mascareñas, a research and development engineer at Los Alamos National Laboratory and lead author of the study published recently in the journal Smart Materials and Structures. "It's a promising phenomenon that we hope to leverage to uniquely identify different pieces of artillery."

In the research, funded by the U.S Department of State, researchers applied Barkhausen noise, a magnetic phenomenon, to two types of steel -- conventional steel and an abrasive-resistant type of steel used in mining equipment. A sensor measured electromagnetic signals by repeatedly scanning the different kinds of steel over a period of time. Researchers compared the signals from those two sets of scanned images and found signatures that were instrinsic to each type of steel.

The variations that occur from the production of various kinds of steel are reflected as distinct fingerprints. "They seem to be repeatable," said Mascareñas.

That intrinsic signature could help to discover counterfeit or low-grade steel parts in construction by looking for differences in the electromagnetic signatures. "It could also help solve that big problem in that industry," said Mascareñas.

Future research could involve studying other types of steel and developing a handheld sensor for treaty verification.
