Webbpowder flow. Not surprisingly, scores ofreferences appear in the pharmaceutical literature, attempting to correlate the various measures of powder flow to manufacturing properties. The development of such a variety of test methods was inevitable; powder behavior is multifaceted and thus complicates the effort to characterise powder flow. Webb1 jan. 1982 · Powders—gaseous, liquid and solid. Powders can float like a gas; flow like a liquid; or support a weight in the same way as hard-packed snow. They behave rather like gases when in the form of smoke or dust in the atmosphere; rather like liquids when poured or conveyed during manufacturing processes; and rather like solids when … WebbMany powders need to be added slowly enough that they have time to be wetted and incorporated into the liquid. Some hydrating thickeners, such as cellulosic polymers, need to be added quickly, while the fluid is still low-viscosity and turbulent to aid the addi- tion and dispersion of the powder. rawnsley road cannock
