Rheometer Accessory Range Extended for UV-Curing Cells

Thermo Fisher Scientific Inc., the world leader in serving science, today announced that it has extended its rheometer accessory range to support UV-curing cell requirements. This meets increasing industry demand to replace thermal curing with UV-assisted thermal curing processes to increase productivity and be more environmentally sustainable.

With common oscillatoric shear methods, it is often difficult to monitor UV-induced reactions that may occur in just a few seconds during coating processes, such as in dentistry. Thermo Fisher developed a “Fast-Oscillation-Mode” for its high-end Thermo Scientific HAAKE MARS rheometer to address this challenge. The new “Fast-Oscillation-Method” allows for a higher data acquisition rate of 500 Hz - independent of the oscillation frequency - to meet the specific needs of very fast curing materials.

Customers now can select between four UV-measuring set-ups:
  • The standard version of a UV-measuring cell is mounted onto a temperature control unit (liquid, electrical or Peltier plate) and is suitable for UV-curing materials such as inks at ambient temperature.
  • A UV-cell for thermal-assisted curing processes at higher temperatures available for the HAAKE MARS. It is integrated into the rheometer’s controlled test chamber (CTC) and covers a temperature range from -150°C to 600°C.
  • A customizable UV-cell with freely configurable distances for optical components such as light guides, condensers and glass plates simulates the arrangements of optical components in production processes, such as those used to manufacture contact lenses.
  • The new module for the HAAKE MARS rheometer platform has been developed for measurements on UV-curing materials. As it is being mounted to the measuring head, it can be used with the rheometer’s Rheonaut module that allows for simultaneous measurements of rheological properties and FT-IR spectra to investigate structural changes within the sample.
A commercially available light source can be attached and triggered via the Thermo Scientific HAAKE RheoWin measuring and evaluation software. Applications such as powder coatings, adhesives, sealants, soldering materials and inks or contact lenses are supported with these measuring cells.

Thermo Fisher Scientific, one of the pioneers in rheology, successfully supports a wide range of industries with its comprehensive Thermo Scientific material characterization solutions. Material characterization solutions analyze and measure viscosity, elasticity, processability and temperature-related mechanical changes of plastics, food, cosmetics, pharmaceuticals and coatings, chemical or petrochemical products, plus a wide variety of liquids or solids.

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
