General Announcements

 

Migration of the Standards Online Balloting System

 

TAPPI Standards Online Balloting System, Kavi, will soon be migrating to TAPPI Connect. The migration will not affect any ballot that is currently opened, nor any roster, ballot results or any member’s information. All the information from the current balloting system (Kavi) will be automatically transferred to the new Workspace where normal activity will continue once the migration is completed.

The website that will be hosting the balloting system (Workspace) is TAPPI Connect, which means that SSIG members will get access to the balloting system with the TAPPI Connect login and password (this is the same login and password that is used for tappi.org). If you are a SSIG member and you don’t have a TAPPI Connect account yet, you may set up one through this link: https://connect.tappi.org/register.

The migration is set to occur the beginning of next week. The new Workspace will look very similar to the current balloting system, so current SSIG members will not need any additional training. However, a free webinar will be provided, hosted by Reid Baldwin of Higher Logic, on Friday, March 22, 2019 at 1:00 pm Eastern, and will cover log in information and any details that may be different between the two platforms. If you are a SSIG member, you should have received an e-mail with the meeting attendance information. If you have not received a meeting invite, please contact the Standards Department at standards@tappi.org.

The webinar will be recorded, in case anyone is unable to attend. Once the recording is available, it will be posted to TAPPI Connect.

Thank you very much for dedicating your time and knowledge to review TAPPI Standards!

 
People

The working group chair below is currently working on a draft to propose a new Standard:

WGC: Martti Tuomisto

Please find below the current scope of this new proposal:

New standard for measuring coating color viscosity at high shear rate.
Method: Capillary viscometer, shear rate 750 000 1/s

Coating colors are non-Newtonian materials, and therefore their rheology is complicated. The most important rheological factor is viscosity, and in case of coating colors it is strongly dependent on a shear rate. Coating color undergoes variable shear rates during the coating
process, varying from zero to several million 1/s. Therefore, measurements are needed in the whole shear rate area for the realistic simulation of coating processes. Rotational viscometers are suitable tools for screening the rheology of coating colors below the shear rate of 50 000 1/s, but
capillary viscometers, such as ACA AX, is needed for shear rates of 50 000 to 1.5 million 1/s.

There are two major groups of factors, which determine the rheology of coating colors: surface chemistry and hydrodynamics. Surface chemistry determines the rheology of coating colors in the low shear rate area (rotational viscometers). There are both attractive and repulsive forces
between the particles. If attractive forces are too strong, particles tend to flocculate. Viscosity increases and suspension becomes unstable. When the shear rate is high enough, structures break down, and viscosity depends mostly on hydrodynamic factors.

The most important hydrodynamic factors are:
- Solids content (i.e. volume fraction of particles)
- Particles size
- Particle size distribution
- Viscosity of continuous (water) phase
- Shape of the particles

ACA AX-100 is a capillary viscometer, which is specifically designed for measuring the viscosity of coating colors under hydrodynamic conditions, i.e. in the high shear rate area. Extrusion pressure is measured with a pressure transducer, and the displacement of the sample
cylinder is measured with a magnetic position sensor. Flow rate through the capillary is calculated based on the displacement of the sample cylinder and measurement time.

Well known, and generally accepted, equations of pipe flow are used to determine a viscosity
value as a function of shear rate. It is also described in the literature and generally accepted that
the pure hydrodynamic viscosity (ie. surface chemistry is not influencing anymore) can be measured at shear rates above 500 000 1/s. However, so far there has not been a standard method to describe high shear viscosity at such high shear rates. We are setting now a new standard at
the shear rate of 750 000 1/s. The standard is applicable to coating colors, surface treatments, pigment slurries, latex slurries etc…

Roll, blade, curtain and jet coating are presently the most used technologies for paper coating at high speeds. Coating colors are subjected to high stresses in all coaters, and shear forces are clearly above 500 000 1/s. Therefore, the new standard method can be used for simulations of
different coaters to help papermakers optimize blade pressures, coat weights and raw materials in order to avoid or solve runnability problems caused by coating colors.

Proposed New Standards and TIPs

The scope of the proposal for a new Technical Information Paper is shown below, as well as the assigned Subject Category, the date when the Work Item was opened, the title of the new proposal and the name of the Working Group Chair (WGC).

0808 - Physical Properties
7/26/18 TIP 0808-XX Measurement of haptic properties of tissue by an objective measuring device

WGC: Giselher Grüner

This is to request development of a TAPPI TIP that would provide a method to characterize the haptic properties of tissue by simulating the human hand by an objective measuring device.
Fundamentals: The haptic feeling of the human hand based on different tactile cells/sensors in our finger tips, what detect vibrations respectively forces, which will be created by moving the fingers over the sample surface as well as by crumpling the sample.
The different cells are sensitive for different frequencies respectively load, what will be generated from the different structure dimensions and specific texture as well as the resistance against deformation (stiffness).
The haptic impression can be split into three basic parameters: micro-surface variations(what can be described as "surface softness"), macro-surface variations (what correlates to "felt roughness/smoothness"), and in-plane stiffness (what correlates to tensile test results).
Because of the nature of our hands and finger tips with the sensor cells, the individual signals will be conducted via nerves to the brain and combined there to an overall impression of the haptic quality of the sample.
Disadvantages of the hand tests are the subjectivity of the results, as well as the fact, that the hand can only feel a combination of the basic parameters. Because of that specific for samples with small differences it is impossible to distinguish by hand, if the difference is felt because of differences in surface softness, or smoothness, or stiffness.
Method and device: The instrument provide parameters, what correlate very good with the three basically parameters of the haptic: micro-surface variations, macro-surface variations as well as in-plane stiffness.
With the software of the instrument it is possible to calculate "HF" hand feel numbers as combination numbers of the three basic parameters (combined with grammage, thickness and number of plies), based on mathematical models of human panels. However, by using the three single parameters separate, information about the relationship of the different components of processes can be obtained.
The provided basically parameters of the device can be used to optimize the tissue production process, because it can help to identify the reasons for changes in overall quality. Because of that it can be used to perform adjustments on the machine, on chemicals or on the pulp. Furthermore it can be used for R&D, benchmarking tests, incoming control in converting.
