Online Natural Coating

Improve your Yankee coating management with new Online Natural Coating measurement and monitoring from Buckman

The wet end of your tissue machine is having an impact on your Yankee coating. All those soluble and colloidal substances that end up precipitating on your dryer are what is referred to as natural coating, and it varies constantly. If your operators could get real time online natural coating (ONC) measurements, they could make proactive coating adjustments that can significantly improve runnability, reduce rejects, improve tissue quality and save blade life. Buckman OnSite® smart technology can now provide real time natural coating levels to you, circumventing the need to spend hours getting each data point via manually testing for it in the lab.

ONC measurement and monitoring gives you all the data you need, when and where you need it.

It’s fast.

Buckman OnSite® ONC capabilities can provide natural coating data points every second, if you wish, which gives you and your Buckman representative the ability to proactively troubleshoot with a considerable amount of baseline data.

It’s comprehensive.

By accurately measuring online natural coating, ONC data helps you to:

  • Identify how changes in fiber quality or type are affecting your Yankee coating.
  • Track the impact of refining on natural coating levels.
  • See, and eventually predict, the impact of any wet end chemical additions like wet strength resins, dry strength resins, CMC and much more.

It’s easy.

Once the baseline control limits are established, proactive alarm warnings will notify the operators or your Buckman representative when coating adjustments may be necessary. The system can send data to either a DCS, a remote computer or smart phone.

It’s accurate.

After Buckman OnSite ONC is calibrated with manual tests, accuracy within a tenth of a milligram per square meter can be achieved, giving you all the accuracy you need to determine proper coating and release feed rates for the Yankee dryer.

It’s automated.

The skid is equipped with an automated flush valve, alarms that can report problems, and an intuitive interface that allows users to easily trigger flushes or reset alarms. When Buckman OnSite ONC detects that the paper machine is down, it will turn itself off but leave water in the line so the pH probe doesn’t dry out. When the machine comes back up, the skid will go through a flush cycle and begin calculating natural coating without human intervention.
