3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 Surface charge surfacecharge Dispersed in an aqueous solution of particles, fibers and fillers charges combined. 3.2 Zeta potential Zetapotential The degree of interaction between charged particles, the particles can be displayed indirectly, fiber and filler surface charge size. 3.3 Streaming potential streamingpotential Stream of charged particles in the opposite ion shear measured by the potential of being separated or, expressed in mV. Particles with a positive symbol indicates potential Charge (positively charged) or negatively charged (negatively charged). Point of zero charge indicate all charges present in the sample is neutralized. Principle 4 Annular electrode means of the sample container and the gate electrode, under vacuum, the sample is sucked into the inlet tube into the sampling container, the gate electrode Formed at the particle/fiber plug. Applying a variable set pressure to generate a flow of liquid through the oscillating particle/fiber plug. Instead of ions scissors Cut to generate a flow potential electrode measured at, you can get a sample of the Zeta potential (see Figure 1). Figure 1 Schematic measurement ......
