Heraeus Noblelight’s shortwave and carbon emitters are suitable for drying protective coatings as they react within one to three seconds, which ensures that heating is controllable.
A scavenger is a chemical substance that is added to a mixture in order to remove or deactivate impurities and marring by-products. ln many reactions, an excess of starting materials is used to drive a solution phase reaction to completion. The final mixture is composed of the desired product and one or more unwanted side products. This article from Hielscher explains the uses of scavengers, the power of ultrasonic mixing and the benefits of ultrasonic scavenging and discusses batch ...
Hielscher ultrasonic reactors are used in many industries to assist and improve the catalytic extraction processing (CEP) or so-called phase-transfer extraction (PTE). Catalytic extraction involves a heterogenous immiscible phase system, such as liquid-liquid or liquid-solid. Ultrasonic high-shear and cavitational forces improve the dissolving rates of solutes significantly, leading to a faster and more complete extraction.
The sonication of coal slurries contributes to various processes during the energy production from coal. Ultrasound promotes the catalytic hydrogenation during the liquefaction of coal. Furthermore, sonication can improve the surface area and extractability of coal. Undesired chemical side reactions during the de-ashing and desulphurisation can be avoided — accomplishing the process in much less time.
Whenever a power or distribution transformer is isolated from the power system, it is likely that residual magnetism remains in the core due to the phase shift. However, residual magnetism also occurs when performing winding resistance tests. As manufacturers use these measurements in their routine testing, transformers can be regularly influenced by the effect of residual magnetism.
Codes and markings, from best-before and lot dates to EAN or data-matrix barcodes to serial batch numbers and various unique identifiers, are there to ensure traceability and product safety, to protect consumers and to avoid counterfeiting. There are many different print techniques that manufacturers can choose, such as continuous inkjet, thermal transfer or laser coding. All of these techniques have their advantages and challenges.
Ribbed wooden decking is common in many public and domestic gardens. However, it does not provide slip prevention as once the decking has been exposed to the elements, particularly without regular cleaning, the moss and mildew build-up will cause the surface to become extremely slippery. This application note from Heskins addresses the question of how to prevent slippery decking.
The argument over the pros and cons of whether or not to install heated water safety showers has possibly run its course with the ANSI.Z358.1-2009 standard now recommending 15 minutes of tepid water drench time for all emergency showers. In this technical article, Janet Dickinson, operations manager at Showers and Eyebaths Services, looks at what emergency safety showers are available that meet current standards.
According to Showers and Eyebaths Services, it is a good idea during milder conditions to conduct an annual service, inspection and compliance assessment for every on-site safety shower, eyewash station and — just as importantly — supply pipe. Ensuring that your emergency showers and eyebaths are fit for purpose and ready to withstand the winter freeze is essential to avoid further problems that may occur when the temperature drops.
