Easier Calibration for Traditional Instruments

From Lab Manager, Nick Riggs

In 2015, Technidyne began offering large format calibration standards for Technidyne Technibrite instruments (TB-1 & Micro TB-1C) to:

  • improve calibration quality - by measuring all 5 points on the same sheet of paper
  • improve ease of use - no more shuffling 2" x 2" tabs
This month, Technidyne is providing another improvement. After extensive testing and verification, we now have only three points for your calibration and verification routines. You obtain the same quality of calibration using our new 3-point calibration tabs and significantly reduce the time you need to spend calibrating and maintaining your instruments.

Once you open your tabs, you'll notice the "F sheet" (felt side, measured sheet) has been reformatted to aid in your 3-point calibration. Instead of 5 measurement positions, you will see that the new measured positions have been circled and labeled 1, 2 & 3, as below:

You will also notice that the traceability form has been updated. The data on the traceability form is now collected and reported automatically, which reduces the potential for human error in producing your calibration supplies. All the information from previous forms is still here, it’s just in a new format. As always, Technidyne is an ISO Level III Authorized Laboratory and calibration supplies for Technibrite™ instruments are still directly traceable to the National Research Council of Canada.

If you have any questions regarding your new calibration standards, please feel free to contact us directly in the Lab, or reach out to your sales and service contacts. Email Nick

Technidyne Brings New Products to Market

In the last two weeks, Technidyne has participated in Conferences in North America and Asia to show new products.

Technidyne participated in PacWest, Whistler, BC, Canada last week. The small, table-top exhibit allowed Technidyne to showcase two new products that have particular importance in that pulp producing area - Color Touch QC and TEST/Plus ISO Brightness.

Color Touch QC
This instrument is specifically designed to meet the needs of long-time Technidyne Technibrite Micro TB-1C users. It provides the basic ISO brightness, color, fluorescence, opacity and whiteness data that those users depend on.

TEST/Plus ISO Brightness
This instrument is specifically designed to meet the needs of customers that only need ISO Brightness data. Pulp producers as well as others can quickly get the brightness data they need quickly.

This week, Technidyne participated in WOW (World of Wipes), Nashville, TN, USA. This exhibit
allowed Technidyne to showcase three products that have particular importance in the world of nonwovens -  Emtec Tissue Softness, Fiber Potential and Charge.

Emtec Tissue Softness Analyzer (TSA)
The TSA gathers all single relevant parameters which have an influence on the tissue softness - smoothness, compressibility, stiffness and “crumpleability“. Additionally it is possible to measure the elasticity and ball burst strength. The correlation of the measuring results to the subjective "hand feel" assessment is excellent.

Emtec FPA touch!
The knowledge of the fiber charge enables a correct and effective dosage of the charged chemical additives. The fiber adsorption of cationic starch, wet strength resin, and many other chemical aids can be easily measured with original samples on-site to optimize the dosage of chemicals in the wet end of the paper manufacturing process.

Emtec CAS touch!
Using standard techniques of titration, the CAS touch! determines cationic/anionic and acid/base demands of aqueous charge systems. Both, Streaming Potential (mV) and pH can be measured simultaneously, making it possible to easily determine isoelectric and flocculation points of a sample and examine the correlation between pH, titrant demand and streaming potential.
Customer’s choice:
The CAS touch! uses integrated high precision titrators, optionally with 1 or 2 titration systems (CAS-I touch!, CAS-II touch!), while also a version for use with external or hand titration is available to the customer (CAS-E touch!).

Interest was so high at WOW that customers were still at the booth as others vendors were tearing down!
Also, this week Technidyne participated in Propack Asia exhibit in Bangkok, Thailand. This exhibit allowed Technidyne to showcase the new TEST/Plus Caliper instrument.

Technidyne's passion for customer satisfaction drives us to be the best in the world at developing economical and creative solutions.

For additional information on any Technidyne, Emtec, Techpap and ACA products, please contact us.

From the Testing Lab: How does moisture affect brightness?

The question was asked by a customer this week, "how does moisture affect brightness?"

In this case the customer is making brightness pads, essentially a rough, wet handsheet. They have measured these for years. Now they are trying to use a wringer and microwave oven to dry the sheet to get a more accurate measurement of dry brightness.

Here are the basic factors at play here:

Moisture (water)
In general, a wet sample will allow more light to transmit through and not be reflected, therefore, the brightness will be lower on a wet sample. The refractive index of water is similar to that of fibers. This is why there is less scattering (reflectance) and more transmittance.
Light on dry sample: reflection, refraction and transmission
Light on wet sample: reflection, refraction and HIGH transmission
A simple test was run using a dry piece of paper. The paper was folded to get an infinite pad and measured on an ISO brightness instrument. The brightness was 82%. The same paper was wetted and measured. The brightness dropped to 60%. This was an extreme example, but it helps illustrate the point....more moisture = lower brightness.

Filler content
Fillers help increase scattering (reflection) and, therefore, increase brightness. If the filler content is very high, there will be fewer pores for water to fill. This will limit the amount of brightness loss due to moisture.

Flatness of the sample
A wet sample is more likely to bulge into the aperture which artificially increases the brightness slightly. Also, drying the sample can result in an uneven surface for measurement which can yield mixed results. Averaging a number of readings is the best approach.

Over drying
Drying a wet sample will increase the brightness. However, if a sample is dried in a microwave, it is very difficult to determine when the sample is dry enough and not over dried. Just like other items in a microwave, the paper sample will likely dry from the inside. Handsheets and pulp pads can often seem fine on the outside, yet be yellow or brown on the inside due to over drying. The fibers on the inside will essentially singe.

The simple answer is that moisture will reduce brightness. The degree of reduced brightness is due in part to the factors described above.

If you have other questions about best practices, lab audits, quality programs, calibration or maintenance, email our Service Manager.

Why Measure Roll Hardness?

Technidyne started selling roll hardness measurement equipment a couple of years ago.  The instrumentation provided much needed improvements over the Schmidt Hammer which was designed for concrete measurement, not paper hardness. Even the Parotester has its limitations. However, our customers were asking for several additional improvements in this technology and measurement area.  The ACA Systems RoQ (roll hardness profiler) provides many advancements.

By taking hardness readings across the roll, uneven, too soft or too hard winding can be detected and the roll can be rejected. This minimizes the risk of complications e.g. during the printing process on paper.

There are several reasons why a ROLL PRODUCER may want to test the roll structure of shipping rolls (or jumbo reels):

  • To determine the cause of specific roll defects such as crepe wrinkles or corrugations
  • As an aid to establishing the winding criteria of a newly installed winder or major rebuild of a winder or reel
  • As a quality control tool to check rolls before they are shipped to an end user

A CONVERTER may want to check shipping rolls received from a roll producer:

  • To determine how specific roll irregularities effect the efficiency of their machine
  • To supply creditable data to enable the roll producer to understand and resolve his concerns.

Rolls that are wound too soft typically may go out of round during transport and storage. If this happens it causes irregularities while unwinding and the only way to compensate for the effects is to slow down the speed of the unwinding machine leading to a loss in production. Rolls that are wound too tightly can lead for example, to bursts within the roll, corrugations on the surface as the web is stretched too tightly, etc.

These variations are very difficult to detect without the aid of a hardness tester, and if they go undetected, serious problems can result. Above all, “it is typically the variation in hardness across a given roll that relates most directly to such converting issues with soft edges being perhaps the biggest contributor.” (TAPPI T 834 om-12 "Determination of containerboard roll hardness")

There are several roll hardness testers available to the Paper Industry. The ACA Systems RoQ uses technology developed specifically for the Paper Industry.  It has the most current technology, user interface and fine resolution.  This device can determine the hardness of large rolls of paper, film and foil. It provides fast, accurate, non-destructive hardness profiles of rolls to assure smooth and efficient printing. As stated above, rolls that are too hard, or too soft, rolls that are unevenly wound, or rolls with different moisture contents can cause difficulties during the printing process.

Improvements in Roll Hardness offered by the RoQ:
  • Rechargeable batteries
  • Integrated touch screen
  • Displays real-time profile data
  • USB data output
  • Barcode reader
  • 1 mm profile resolution
With over 60 roll hardness units already installed in North America by Technidyne, and with many of the new RoQ units on order, Technidyne customers are experiencing the cost savings associated with modern technology.
