  • Effects of Oversize Particles on the Density of Clean Granular Soils

    Fill material often contains particles too large to be tested in conventional testing equipment. In order to evaluate the compaction, strength, and deformation characteristics of soil containing such oversize particles, a modeling criterion is required which specifies how the soil minus the oversize particles (the soil matrix) should be tested. Questions such as whether or not to replace oversize ...

  • Refractories, plastics, insulation or textiles containing chromium compounds - Case study

    Purpose The original version of this Plant Service Bulletin (PSB-43) was issued in April of 1990 to alert owners and operators of boilers and steam generators that certain materials containing chromium may, under certain operating conditions, produce hexavalent chromium (Cr + 6), a carcinogen. It also suggested remedial action and substitute materials. The initial issue of PSB-43 ...

  • Used Furnaces & Ovens

    Industrial ovens and furnaces are both heated chambers used to process raw materials at higher temperatures than what can be obtained in open-air systems. There is a range of heat treatments possible with both industrial furnaces and ovens, and the main purpose of any heat treatment is to change the mechanical of physical properties of a material. Some examples of materials that benefit from heat ...

  • Influence of Voids on Density Measurements of Granular Materials Using Gamma Radiation Techniques

    The use of gamma radiation equipment for the nondestructive measurement of soil density originated nearly four decades ago. The typical procedure involves a careful calibration of the gamma radiation counts on specimens of known density of the same materials as those whose density are to be measured. This paper presents the results of laboratory gamma-ray density measurements on 100-mm-diameter ...

  • Measuring Geomembrane Tensile Strength – 1” or Dumbbell?

    Abstract: Specifying a tensile strength or % elongation for any given application is necessary to avoid any possible failure in the geomembrane.  There are many factors to consider including: testing equipment, thickness, load cell, type of grips, and sample geometry.  Although ASTM D7176 currently requires a 1” tensile strip, they will be considering a dumbbell-shaped sample as ...

  • Get the Lead Out - Standards Aid in RoHS Compliance

    RoHS, the seminal European sustainability directive, and others like it challenge manufacturers to eliminate hazardous substances in their products. With RoHS compliance deadlines ongoing through at least the next five years, and more to come from other regions and nations, ASTM Committee F40 is helping companies with testing standards and other resources. The recent introduction of the new Apple ...

  • Plastics pellet manufacturer eliminates blend problems with uniquely designed rotary blender

    Having no internal moving elements, blender achieves 100% discharge eliminating process problems. To remain competitive in a widening world economy, manufacturers have to provide quality products at world market competitive prices. This has forced American manufacturers to rethink their approach to manufacturing. Particularly, rethink the cost effectiveness of their ...

  • Beyond Laboratory Research on White Rust and Passivation

    EVAPCO initiated an in-depth study to investigate the formation and control of white rust. This study, which began over three years ago, led to the development of industry-leading research equipment specifically designed to evaluate white rust formation on evaporative heat transfer surfaces. A small-scale closed circuit cooler was designed and built to replicate the dynamic conditions ...

  • Moving difficult-to-handle bulk materials with flexible screw conveyors

    Flexible screw conveyor systems can be engineered to transport bulk materials that tend to pack, cake, smear, break apart or fluidize, and can prevent the separation of blended products. Flexible screw conveyors (Fig. 1) are suitable for most bulk materials, from sub-micron powders to large pellets, both free-flowing and non-free flowing. They are capable of conveying bulk materials at any angle ...

  • Fabrication of polysiloxane-modified polyurethane sponge as low-cost organics/water separation and selective absorption material

    Through sol-gel and dip-coating processes, commercial polyurethane sponge modified by polysiloxane was fabricated under low temperature (60 °C) and atmosphere. The contact angle of the obtained polysiloxane/polyurethane sponge is 145 ± 5°. Hence, the polysiloxane/polyurethane sponge could float on water and selectively absorb organics from the surface of the water, indicating simultaneous ...
