Using DSR has costly implications.
YOUR CHALLENGE:
Using DSR has costly implications.
Although dry strength resins can give strength increases in paper, they do add cost and operator complexity.
DID YOU KNOW?
The negatives associated with DSR are related to the charge mechanism used to generate its strength.
SO WHAT?
As a result, many tissue makers must deal with felt filling, the negative impact on the Yankee coating and increased microbiological issues.
As the wet end charge demand changes due to variable pulp quality, the DSR performance changes, too, and must be adjusted, requiring operator intervention. This increases operator complexity.
Also, DSR bonds are significantly stronger than hydrogen bonds as would be expected. Creating these stronger bonds reduces sheet flexibility and increases stiffness. A sheet at a given tensile using hydrogen bonding will be more flexible than one using a combination of hydrogen bonding and ionic and covalent bonds of dry strength.
THE SOLUTION:
THE SOLUTION:
Eliminate the use of dry strength resin.
Eliminate the use of dry strength resin.
You wouldn’t have the cost, handling, sheet stiffening or operator complexity associated with DSR. You would free up more bonding sites for other functional chemistries and avoid felt filling and charge imbalances.
HERE’S WHAT YOU NEED TO DO TO MAKE IT HAPPEN:
Increase strength, efficiency and potential simultaneously.
