Sweeping compound

Underwriters Laboratories 333 Pfingsten Road Northbrook, Id. 60062 Standards for Safety is ahst of more than 200 standards that provide specifications and requirements for constmetion and performance under test and in actual use of a broad range of electrical apparatus and equipment, including household appHances, fire-extinguishing and fire protection devices and equipment, and many other nongenerady classifiable items, eg, ladders, sweeping compounds, waste cans, and roof jacks for trader coaches. 

Prevent dry, dusty pesticide spills, such as dusts, powders, or granules, from becoming airborne by covering them with a sweeping compound or a plastic covering or by very lightly misting the material with water. Do not mist too much, because water may release the pesticidal action or may cause the pesticide to form clumps and be unusable. 

Use Decolorizing of oils and other liquids, oil-well drilling muds, insecticide carrier, floor-sweeping compounds, cosmetics, rubber filler, carrier for catalysts, filtering medium.

Magnesium chloride is used to make disinfectants, fire extinguishers, paper, and floor sweeping compounds. It is made from the redox reaction of hydrochloric acid with solid magnesium hydroxide. Write a balanced equation for this reaction, which yields aqueous magnesium chloride and liquid water.

A method for estimating the true compound temperature is illustrated in Figure 10.2, which shows the temperature recorded by thermocouple, the stock temperature, J, measured directly by a probe and the stock temperatures estimated from the temperature difference, - 2> of other runs. These - 2 values were added to the t 2-curve of this run to obtain the J-curve. It was assumed that the temperature difference between the curve and the 2-curve increased smoothly with the rise of the stock temperature. This is based on the previously stated interpretation that the temperature difference, - 2> is caused by the heat-sink effect on the thermocouple. Such an effect is expected to increase with rising stock temperature. The fact that the pattern of 2-curves is very reproducible means that the temperature non-uniformity within the compound is not registered by the thermocouple. This is probably due to the time lag of the thermocouple, which averages out the temperature non-uniformity of the very rapidly sweeping compound. 

Over the last few years at the Flexsys laboratories in Akron, OH, data has been collected on both RPA and PICO abrasion as discussed above. In total more than 500 compounds have been tested. RPA loss modulus strain sweeps and PICO abrasion results have been collected and compiled into a database. The diversity of this database is rather broad. Many formulations based on NR,... 

At sufficiently low strain, most polymer materials exhibit a linear viscoelastic response and, once the appropriate strain amplitude has been determined through a preliminary strain sweep test, valid frequency sweep tests can be performed. Filled mbber compounds however hardly exhibit a linear viscoelastic response when submitted to harmonic strains and the current practice consists in testing such materials at the lowest permitted strain for satisfactory reproducibility an approach that obviously provides apparent material properties, at best. From a fundamental point of view, for instance in terms of material sciences, such measurements have a limited meaning because theoretical relationships that relate material structure to properties have so far been established only in the linear viscoelastic domain. Nevertheless, experience proves that apparent test results can be well reproducible and related to a number of other viscoelastic effects, including certain processing phenomena. 

To study NMR spectra of compounds, apparatus is required that consists of three sets of components. These are a radio-frequency transmitter, a homogeneous magnetic field and a radio-frequency receiver. In addition to these, the apparatus includes a unit to sweep the magnetic field over a small range, a mere few parts per million. 

The earliest NMR technique to gain importance in chemistry was that of proton NMR. Spectra could be obtained for compounds containing the nucleus by continuously sweeping the field at constant frequency. This... 

In this chapter, the voltammetric study of local anesthetics (procaine and related compounds) [14—16], antihistamines (doxylamine and related compounds) [17,22], and uncouplers (2,4-dinitrophenol and related compounds) [18] at nitrobenzene (NB]Uwater (W) and 1,2-dichloroethane (DCE)-water (W) interfaces is discussed. Potential step voltammetry (chronoamperometry) or normal pulse voltammetry (NPV) and potential sweep voltammetry or cyclic voltammetry (CV) have been employed. Theoretical equations of the half-wave potential vs. pH diagram are derived and applied to interpret the midpoint potential or half-wave potential vs. pH plots to evaluate physicochemical properties, including the partition coefficients and dissociation constants of the drugs. Voltammetric study of the kinetics of protonation of base (procaine) in aqueous solution is also discussed. Finally, application to structure-activity relationship and mode of action study will be discussed briefly.
