Determination of wet end Zeta Potential
1 Scope
This standard specifies the method for determining the wet end of the paper by Zeta potential flow potential.
This standard applies to the paper in an aqueous solution of fibers, fillers and pigments Zeta potential measurement.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

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).
