New Approach to Dry Strength
During the past two years, Bercen has been developing a new approach to dry strength. (Patent Pending 2008/0216979A1). Glyoxalated Polyacrylamide (GPAM) is one of the most widely used dry-strength additives. Despite its widespread use, there are several shortcomings among existing products, including poor shelf life, low solids, and very poor control over managing the gel point of the product.
The poor shelf life typically has 30 days before the reaction reaches a gel point where it could be an issue for plugging of the pipes and frequent cleaning of the bulk tanks. The low solids translates into high freight costs. After running multiple pilot studies Bercen has concluded applying the GPAM close to the gel point increases the efficiency of the product significantly.
Bercen has developed a piece of equipment that solves all of the shortcomings of the conventional GPAM and puts increased efficiency and cost saving in the control of the mill. This unique process allows the mill to manufacture GPAM on site allowing the mill to control all of the critical parameters.
The keys are precise temperature control and the use of a unique Bercen glyoxal blend that allows the reaction to occur when it is most effective in developing dry strength. We at Bercen have utilized technology that allows us to dial in the required temperature with the accuracy of plus or minus 1 degree F. This process will allow the mill to reduce the volume of product used by 75%. Bercen is proud to not only provide a more efficient use of an existing chemistry but this approach will have a tremendous effect on reducing the mill’s carbon footprint.
