DEVCON® DFENSE BLOK™ REVOLUTIONIZES WEAR & ABRASION PROTECTION

DFense Blok™ wearing compound, from ITW Devcon®, is specially formulated to outperform and outlast traditional epoxy wear and abrasion products — even in the most severe impact and sliding abrasion conditions.

DFense Blok™ is a new, innovative alumina ceramic bead-filled epoxy compound that, when used with DFense Blok™ Surface Wetting Agent, drastically increases drop impact strength over 1” ceramic tile (tested using 85 lb. weight with 0.25 sq. in. striking surface). Abrasion resistance is significantly better than traditional epoxy products (per grit-blast abrasion testing: #14 silicon carbide blasted at 40 psi, 45° angle). DFense Blok™ Surface Wetting Agent is a 2-part thixotropic epoxy gel system that improves the ease of application and cured adhesion properties of DFense Blok™ wearing compound.

DFense Blok™ is ideal for use in repairing, rebuilding and protecting typical wear and abrasion applications such as pipe elbows, scrubbers, ash handling systems, cyclones, fan blades, pump boxes, float cells, screw conveyors and augers, etc. In areas that cannot be welded or where sufficient surface preparation cannot be performed, it is recommended to first apply a coat of DFense Blok™ Surface Wetting Agent. DFense Blok™ can also be used in place of abrasion-resistant metal and ceramic tile.

Available in 30-lb. pails, DFense Blok™ is mixed in a 2:1 ratio and has a working time of 25 minutes at room temperature. A non-sagging compound, it can be easily applied by trowel at thicknesses of ¾” on vertical surfaces and ½” on overhead surfaces. It achieves functional cure in only 4-5 hours, allowing equipment to be returned to service in hours, not days. It has superior wear and abrasion resistance, withstands high-impact conditions and withstands service temperatures up to 300°F.

Using DFense Blok™ Surface Wetting Agent significantly improves the adhesion of DFense Blok™ compared to traditional epoxy products (per ASTM D 1002). Once it has been applied, there is no wait time before applying DFense Blok™ wearing compound. DFense Blok™ Surface Wetting Agent’s orange color ensures complete surface coverage and facilitates visual inspection. A single 1-pound kit provides enough surface coverage for 30 pounds of DFense Blok™.

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

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

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.
